[11:45 PM, 8/14/2021] Abhijeet Singh: Summary of Today’s Chatshaala(14th August 2021)
Today, chatshaala started with my(Abhijeet) journey in Cube since I joined i.e from 7th std. So I joined and started working on Mosquito project with my friend collaborators from my school only. We used to catch mosquitoes collaboratively and individually at school and our respective homes. The aim was to predict that in which month the number of mosquitoes will increase (because of which we maybe able to see increase in the number of mosquito born diseases for example malaria etc) in our locality so that we can prevent it from happening by destroying the possible breeding site of mosquitoes which includes water collected in thrown water bottle, coconut shell, pot holes besides roads, gardens and anywhere were water is collected as mosquitoes lay eggs in that.
We also worked on Earthworm, daphnia culturing, and snails.
Till 9th I worked then took break for 3 years for 10th and 12th board exams.
After that we discussed about what Ashwathy has been doing since when she joined that is I guess April 2020. Discussion on trapping was done then ashwathy told that she was mainly trying to find Drosophila Melanogaster from the traps through which she used to catch fruitflies. Discussion on why D.melanogaster is taken as model organism was done and turns out that it genes similar to that of humans and the sleep-wake cycle or activity rythm too Also many nobel prize has been announced with D.melanogaster studies
We can onto the discussion that what’s the difference between Model organism and Model system. At 1st we were confused with the terms but after discussion we came to an understanding that both are one and the same it’s just how an individual keeps it in front of us with respect to the organism he/she is working with.
Again we came to discuss the activity pattern or rythm of fruitflies with the help of Ashwathy’s work. So ashwathy tried to explain it with the help of a setup. So what we get was that Fruitflies are active during day time and very much or almost inactive at the night time as of with humans.
[11:47 PM, 8/14/2021] Abhijeet Singh: The whiteboard image will be shared soon.
[2:02 PM, 8/15/2021] Lydia cUBe Drosphila: Interesting Chatshaala board discussions!
What was the context for discussing imaginal disc?
[2:05 PM, 8/15/2021] Lydia cUBe Drosphila: Interesting!
Looking for more information on this
Biomimetics is a field that is gaining more interest these days.
Are there any current studies that are going on in this area?!
[2:08 PM, 8/15/2021] Lydia cUBe Drosphila: Yes
Do you have cultures that are working well for a month or more?
Would be good to show others as a proof!
[2:12 PM, 8/15/2021] Lydia cUBe Drosphila: Okay
So why not track the history of those flies? We can find out the exact reason for the death of the flies so that it does not repeat again
[2:14 PM, 8/15/2021] Lydia cUBe Drosphila: Great
Have you made a plan for that?
Why not send a detailed plan as to how you will go about ahead?
All the collaborators will also help you
[2:21 PM, 8/15/2021] Lydia cUBe Drosphila: Thank you, Abhijeet, for this summary!
What do you think of Aswathy’s circadian rhythm studies on fruit flies? What were the learnings from yesterday’s discussion? VIDEO SHARED BY BATUL AT 2.49PM
BREAKING NEWS Dense growth of nematodes on raw potato slice B subculture observed using magnifying glass of 10X and phone camera 4X .The set up was started on 6/8/21 nine days ago with 4drops of milk and nematodes from original culture started with soil.Cubehomelab Kolkata 15/8/21Batul
[2:51 PM, 8/15/2021] Abhijeet Singh: Yes @Lydia cUBe Drosphila di.
This is interesting indeed!
Yes like humans now tend to look towards nature for the solutions of modern issues, that nature has been doing for years!
So biomimetics came up with that only I guess.
Just to give you context about how this discussion started at 1st place is that, my mom planted some karela seeds last week June or something. After a week or two I saw that how beautifully they are growing and I posted pictures in the group (Earlier chat, please follow the thread to see it). So @Arunan HBSCE found some paper with how these climbing plants are becoming an inspiration for the development of robots to face the modern issues. I’m going through that paper only actually.
As far as current studies are concerned, I didn’t look for them yet. I did some random searches to find if something has achieved in this feild but I’ve look for it more clearly. I’m going through the paper that sir sent and trying to understand the technique and methodologies they are using to do so…
I’ll keep following up this thing and look for more references! Please keep asking me for follow ups if I left somewhere. @Lydia cUBe Drosphila
[3:03 PM, 8/15/2021] Abhijeet Singh: The work that @Aswathy Suresh CUBE di is doing since last year is incredible. The activity pattern or circadian rythm is very intersting.
The thing that I’m actually amazed of is that she has been culturing the fruitflies which she caught last year. And she told that she has cultured over 40 generation of flies which is absolutely amazing.
This is gr8 @Aswathy Suresh CUBE . Please let me know what are your further plans with it!!
Learning that we got was that it is absolutely okay to get confused with terms which we think we know. As we were discussing about Model Organisms and Model System so getting confused is okay. But the thing we should actually address these things often to be clear in the end.
[3:08 PM, 8/15/2021] Arunan HBSCE: Camera is shaking. Please take better photos. @Batul Pipewala Kolkata
[3:13 PM, 8/15/2021] Arunan HBSCE: @Abhijeet Singh Please keep discussing with others, while you read the paper and say what you understood and where you are not clear.
Let’s do it collaboratively, by making mistakes and progressing together! @Abhijeet Singh @Lydia cUBe Drosphila
[3:18 PM, 8/15/2021] Arunan HBSCE: Yes, getting confused is not only ok, but knowing that recognition of our confusion is the first step towards acquiring clear knowledge What fo you say? @Abhijeet Singh @Aswathy Suresh CUBE @Lydia cUBe Drosphila
Open discussion clarifies and leads to constructing knowledge!
What do you say? @Abhijeet Singh
[3:20 PM, 8/15/2021] Arunan HBSCE: Please post photo updates and further plan of work in your setting up of Single Line Cultures of Tanniam Fruitflies @Sidhy Kerala Drosophila
[3:22 PM, 8/15/2021] Arunan HBSCE: Please share the details of these to establish better collaboration. @Lakshmy PJ CUBE

[10:40 PM, 8/15/2021] Lydia cUBe Drosphila: Great!!
A beautiful context for inspiration to understand more on biomimetics!
I too had karela plant in my house balcony. I don’t have them now… But now I’ll also plant some karela seeds and try to correlate and see if I can find something interesting!
Even I’ll look on this topic more w.r.t. to current studies in this field…we can find something and understand together!
[10:43 PM, 8/15/2021] Lydia cUBe Drosphila: Yes that’s really great!
We need to follow up with @Aswathy Suresh CUBE so that she can do more such works and inspire other collaborators as well! Follow up on other collaborators as well! @Yash Sheregare CUBE too is having an incredible fruit fly culture with him! Looking forward to current updates from all the collaborators!
So, what’s the difference between model organism and model system?
[10:44 PM, 8/15/2021] Lydia cUBe Drosphila: Yes Sir!
That’s what I also said!
I too got interested in this topic! Even I’ll look for papers related to current studies or the studies that have been done in this field!
[10:48 PM, 8/15/2021] Lydia cUBe Drosphila: That’s what we majorly do in CUBE!
Celebration of our goof-ups!
Confusion is sometimes considered a mistake by some. Acknowledging those downfalls, confusions and mistakes helps us in understanding things in a better way! @Aswathy Suresh CUBE @Abhijeet Singh @Yash Sheregare CUBE

[11:11 AM, 8/16/2021] Aditiya Joshi CUBE: Objective: to keep the coconut water for fermenting (toddy) and try to grow the yeast/bacteria/fungi from the fermented coconut water on boiled potato slice.
Setup: two transparent plastic bottles (250ml). These were washed using dilute soap solution to clear the remnants of the contents. Then washed with water 4 times properly to clear all the soap. Dried overnight. Coconut water was collected in a container and then poured in these two bottles. One is kept open and other us capped. Kept by a wall in balcony.
Expectation: the coconut water in open bottle will show bubbles, change in smell and color indicating fermentation after 24 hours. The coconut water in capped bottle too will show these signs of fermentation but lesser compared to open bottle due to less exposure to microbes.

[11:21 AM, 8/16/2021] Shraddha Sonavane CUBE:
[11:28 AM, 8/16/2021] Aditiya Joshi CUBE: What I think or expect is, the coconut water will become more turbid. Color change here was meant by this.
[11:33 AM, 8/16/2021] Aditiya Joshi CUBE: Beautiful @Abhijeet Singh
I remember this term biomimetics once used in a show on discovery chanel.
There, they referred to gecko lizards. These lizards can walk on varying surfaces including smooth glass.
So, the ppl are studing the structure and design of their legs and footpads. By this, they can make some appliances like robots or vehicles which can walk on different surfaces.
Interesting @Abhijeet Singh . Keep discussing.
[11:34 AM, 8/16/2021] Seethalakshmy CUBE: Ok

[11:57 AM, 8/16/2021] Aswathy Suresh CUBE: SUMMARY
CUBE - Chatshaala
15.08.2021
Discussed about smelling sense capacity of 2 different D.melanogaster one from native (brought it from kitchen area) & another from Lab cultured fruit flies more than 70years passed (CsBz melanogaster - one of the lab bred).
Long term objective :
To perform olfactory assay at range of concentrations of IAA (banana essense)
using standard CsBz 2nd instar larvae and Native Drosophila 2nd instar larvae and compare their olfactory sensitivity to comment on evolutionary changes in terms of fruit odor smelling!
Hypothesis :
Native have good smelling senses compare to Lab bred one which are passed more than 70years, 3360 generations covered.
Possibilities :
Native want to find their own food so their antenna receptors always functional . But Lab bred culture flies don’t want find their food because of availability of food, Compare to native CsBz will have less functional.
CsBz flies almost passed 3360 generation in this 70 year. So, there could be possible some mutants will be form inside the culture. Because these flies culturing in closed environment could be chance mutants will serve inside culture. [ Mutation is a big word - here less sensing smell capacity mention about mutants.
How can we check their smelling capacity through experiment! is it possible we can do it in our home ?
Surely we can do it in our home using what are available in our home…
We can replace Lab materials in to home materials to perform this Olfactory experiment
How to calibrates olfactometer working or not through control experiment? How can Calculate mean !? Connected Biostatistics

[12:25 PM, 8/16/2021] Lydia cUBe Drosphila: Nice setup!
What’s your plan with this Aditya?
And on what basis did you select coconut water for yeast/bacterial growth? Any reference or any experience/context behind this
[12:26 PM, 8/16/2021] Lydia cUBe Drosphila: What is your plan with potato slices?
[12:31 PM, 8/16/2021] Lydia cUBe Drosphila: Ohh nice! Can this be connected to the model systems that we all work on? A context to curriculum area of Biomimetics connected to any of the model systems? Just thinking
[12:32 PM, 8/16/2021] Lydia cUBe Drosphila: Thank you @Aswathy Suresh CUBE for the summary!
What’s the plan of all fruit fly collaborators for carrying out the olfactory experiment at home? How is it possible? And most importantly why do we have to do this experiment?
[12:42 PM, 8/16/2021] Arunan HBSCE: Please give a summary of your work when you were in school, especially with reference which months you got to see Aedes mosquitoes, more and in which months less? @Abhijeet Singh

[12:48 PM, 8/16/2021] Arunan HBSCE: post*
[12:50 PM, 8/16/2021] Aswathy Suresh CUBE: Yes, currently i have 2 good subcultures SLBK B19, E15 - 46 days old culture (subculture started date - 02.07.2021) more than passed 1 month have Larvae, Unhatched pupae, also have adult flies as well inside culture.
[12:51 PM, 8/16/2021] Aswathy Suresh CUBE: How can we found what could be the reason that those flies death?
[12:54 PM, 8/16/2021] Arunan HBSCE: In that case, why not repost with this clarification using precise terminology. @Aditiya Joshi CUBE
[12:58 PM, 8/16/2021] Aswathy Suresh CUBE: I didn’t made a any proper plan ma’am, (Because even making more subculture thats also make more difficulty finding more bottles.) So Iam thinking which culture facing major problems… only that culture can make more subculture in order to save the progeny’s of particular single line cultures.
[1:09 PM, 8/16/2021] Aswathy Suresh CUBE: Which mosquito is this? @Hina Mudgal Kanpur CUBE mam
[1:13 PM, 8/16/2021] Aswathy Suresh CUBE: Nice setup @Aditiya Joshi CUBE . What is your expectations?
[1:19 PM, 8/16/2021] Aswathy Suresh CUBE: Is there any special breeding season in Aedes mosquitoes? @Dr. Sarita kumar Delhi CUBE mam
[1:43 PM, 8/16/2021] Dr. Sarita kumar Delhi CUBE: Aedes breeds best at 27 degree Celsius and 80-85% humidity. Rainy season with high humidity, and optimum temperature is best…
[1:49 PM, 8/16/2021] Abhijeet Singh: Yes yes! Ashwathy to me about the culture that @Yash Sheregare CUBE is having.
So like as I mentioned earlier that getting confused with terms os okay and only an open discussion can help us to get through with it!
So what we get to know is that there’s no difference in Model system and model organism. It’s just the matter of terms and how an individual express it to us.
So model system or model organism is a non-human species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the model organism will provide Insight into the workings of other organisms
To elaborate :- if anyone want to study a biological process and in order to do that he/she selects a particular species so that species …
[1:53 PM, 8/16/2021] Abhijeet Singh: Yes yes!
That’s exactly what biomeimetics is all about!
Yes I’ll keep Posting my understanding about it!
Please get the discussion going @Aditiya Joshi CUBE !!
[2:06 PM, 8/16/2021] Arunan HBSCE: Do t you think it is high time you subculture these flies of 46 day old:upside_down_face: culture? @Aswathy Suresh CUBE
[2:26 PM, 8/16/2021] Batul Pipewala Kolkata: I am not making a claim of transferring a single nematode because larvae could be attached to even one nematode picked up from the potato surface.
[2:28 PM, 8/16/2021] Batul Pipewala Kolkata: My objective is to maintain the nematodes isolated from the soil sample.As one potato slice culture begins to die in around 14days I have transferred the nematodes before that stage occurs to fresh potato slices C1and C2
[2:55 PM, 8/16/2021] Seethalakshmy CUBE: Sir,
When vinegar add to the Milk
This is a chemical reaction. In this activity, the milk is heated and then mixed with the white
vinegar or lemon juice, which is an acid. The heat and the acid cause the protein casein in the
milk to denature, or break apart. This is a change on the molecular level. Chemical changes
occur on the molecular level, while physical changes remain the same on the molecular level.
[2:58 PM, 8/16/2021] Seethalakshmy CUBE: Milk contains a protein called casein and it is negatively charged….vinegar contain hydrogen ions which are positively charged. Hence when u mixed these two together the hydrogen ion and the casein protein attract each other and form white plastic like lumps called curd and the process is called curdling.
[3:10 PM, 8/16/2021] Sunita Chahar CUBE: Birds nest fungi in our garden
[3:10 PM, 8/16/2021] Sunita Chahar CUBE: Bhandup Mumbai
[3:11 PM, 8/16/2021] Seethalakshmy CUBE: Wow!! What is this? @Sunita Chahar CUBEma’am
[3:17 PM, 8/16/2021] Seethalakshmy CUBE: The curd is produced due to the presence of reaction between lactic acid bacteria and the milk protein casein. Lactic Acid or milk acid is an organic acid with chemical formula C3H6O3. When milk sugar or lactose undergoes fermentation, the product obtained is lactic acid. It is found in cottage cheese, leban, sour milk, yogurt, and Koumiss.
[3:22 PM, 8/16/2021] Arunan HBSCE: But, we can do that too, meaning, transferring a single nematode for culturing whole generations from that. What about that? @Batul Pipewala Kolkata What precautions?
[3:29 PM, 8/16/2021] Arunan HBSCE: What do you mean by denaturing of Casein protein? @Seethalakshmy CUBE
[3:37 PM, 8/16/2021] Arunan HBSCE: Is there a connection between Lactic acid of curd and Acetic acid of Vinegar in curdling? @Seethalakshmy CUBE
[3:39 PM, 8/16/2021] Seethalakshmy CUBE: Sir,
Denaturation, in biology, process modifying the molecular structure of a protein. Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state. Denatured proteins have a looser, more random structure; most are insoluble. Denaturation can be brought about in various ways—e.g., by heating, by treatment with alkali, acid, urea, or detergents, and by vigorous shaking.
Reference : Denaturation | Definition, Examples, & Facts | Britannica
[3:41 PM, 8/16/2021] Arunan HBSCE: How do you explain in your language for all to understand. @Seethalakshmy CUBE
[3:43 PM, 8/16/2021] Seethalakshmy CUBE: Sir , it means The original structure of protein is changes in to another form it is irreversible.
[3:44 PM, 8/16/2021] Aditiya Joshi CUBE: @Aswathy Suresh CUBE I expect to see fermentation in both the bottles. But more fermentation will be seen in the open bottle than the closed. Or the open bottle will show fermentation sooner than the later.
Then I will be spreading the fermented coconut water from both bottles on the boiled potato slices and try to see if there are colonies of the yeasts/bacteria from fermented coconut water grown on the potato slice.
[3:45 PM, 8/16/2021] Seethalakshmy CUBE: Irreversible means - they can’t reach previous form
[3:46 PM, 8/16/2021] Arunan HBSCE: Good. But, how? @Seethalakshmy CUBE Please give an example?
[3:48 PM, 8/16/2021] Arunan HBSCE: Why not?
[3:51 PM, 8/16/2021] Arunan HBSCE: Why not?@Seethalakshmy CUBE
[3:53 PM, 8/16/2021] Aditiya Joshi CUBE: https://courses.lumenlearning.com/introchem/chapter/denaturation-and-protein-folding/
If the protein is subject to changes in temperature, pH, or exposure to chemicals, the internal interactions between the protein’s amino acids can be altered, which in turn may alter the shape of the protein. Although the amino acid sequence (also known as the protein’s primary structure) does not change, the protein’s shape may change so much that it becomes dysfunctional, in which case the protein is considered denatured.
[3:53 PM, 8/16/2021] Seethalakshmy CUBE: Sir, in chemistry we use many terms like deactive, denatured…
Here deactive means they deactive at a particular time/ particular temperature. If they reach its suitable time they active.
This process is reversible.
But denatured means they loss all capacity to form previous str. Here in the case of casein protein they denatured. By using vinegar. The action of vinegar completely changed it’s structure
[3:54 PM, 8/16/2021] Aditiya Joshi CUBE: Example of egg is given here
[3:55 PM, 8/16/2021] Aditiya Joshi CUBE: Denaturation Protein
[3:57 PM, 8/16/2021] Arunan HBSCE: Please describe in your own words for all to understand @Aditiya Joshi CUBE
Protein denaturation is also a consequence of cell death. Denatured proteins can exhibit a wide range of characteristics, from conformational change and loss of solubility to aggregation due to the exposure of hydrophobic groups. Denatured proteins lose their 3D structure and therefore cannot function. PHOTOS SHARED BY DP AT 4.47PM: Can any of you identify this insect? The body is about 2-3 mm without the front antenna.
[4:48 PM, 8/16/2021] DP HBCSE: It has two long stripes along the body, has a relatively long head or snout.

[4:59 PM, 8/16/2021] Seethalakshmy CUBE: Yes, @Aditiya Joshi CUBE we can take this example for denaturation.
The egg white contains protein ( which known as albumin )it is transparent and liquid.
When we boil/ cooking the egg white turns into opaque and soild.
This is dueto denaturation of protein.
When food is cooked, some of its proteins become denatured. This is why boiled eggs become hard.
The same process is occur when we add vinegar into milk.
I think what I said was clear. If you do not understand something, please ask.and correct me if iam wrong. @Arunan HBSCE sir, @Aditiya Joshi CUBE, @Aswathy Suresh CUBE, @Lydia cUBe Drosphila, @KIRAN CUBE ma’am,@Batul Pipewala Kolkata ma’am, @Man Masih Beck RANCHI CUBE, @Abhijeet Singh and others PHOTO SHARED BY Arunima AT 5.06PM:

where did you find this? @DP HBCSE sir
[5:32 PM, 8/16/2021] DP HBCSE: At my office. I sit in front of a window which has this tree. It was crawling and then hopped off. It didnot have any wings, so I assume it hopped and not flew.
[5:38 PM, 8/16/2021] P. Chitralekha Cube JNU: But denatured means they loss all capacity to form previous st.
Not always true. Check Anfinsen’s experiment which fetched him the 1972 Nobel prize.
[5:42 PM, 8/16/2021] P. Chitralekha Cube JNU: Except that in one temperature is changed and in the other pH. How do these changes denature proteins? Why doesn’t boiling milk denature the proteins in milk?
[5:44 PM, 8/16/2021] Seethalakshmy CUBE: Ma’am can you send reference?

[5:50 PM, 8/16/2021] P. Chitralekha Cube JNU: Anfinsen's dogma - Wikipedia
[6:00 PM, 8/16/2021] Seethalakshmy CUBE: Not all proteins are thought to be affected by temperature. Some proteins are denatured at very small temperatures. A specific temperature is required for each protein to denaturation .
[6:04 PM, 8/16/2021] P. Chitralekha Cube JNU: Why? How does higher temperature denature proteins?
[6:08 PM, 8/16/2021] Seethalakshmy CUBE: The weak forces between charged groups and the weaker forces of mutual attraction of nonpolar groups are disrupted at elevated temperatures, however; as a result, the tertiary structure of the protein is lost. … When denaturing agents are removed from a protein solution, the native protein re-forms in many cases.
[6:13 PM, 8/16/2021] P. Chitralekha Cube JNU: If temperature is lowered after denaturing the protein, will the protein regain its native form?
[6:14 PM, 8/16/2021] Seethalakshmy CUBE: That’s also a confusing factor
[6:18 PM, 8/16/2021] P. Chitralekha Cube JNU: Basic question to be addressed is why do proteins denature? Is there a reversible and an irreversible denaturation?
[6:20 PM, 8/16/2021] Seethalakshmy CUBE: The body strictly regulates pH and temperature to prevent proteins such as enzymes from denaturing.
Some proteins can refold after denaturation while others cannot.
Yes ma’am the reference says some protiens can re - gain it’s previous str.

[10:57 PM, 8/16/2021] Lydia cUBe Drosphila: Good!
Please post pictures and videos of these cultures. Looking forward to it.
[11:03 PM, 8/16/2021] Lydia cUBe Drosphila: You might be having dates of all those cultures bottles.
We’ll track each bottle one by one
For eg. If B is the bottle in which your flies died, then write a post here of the B bottle specifically with date of transfer of flies into B bottle, number of flies transferred, bottle name from which the flies where transferred (suppose A) into B bottle, then dates of when larvae, pupae were seen (if seen) in bottle B.
Similarly, write the history of bottle A as well from which the flies were transferred into B.
[11:10 PM, 8/16/2021] Lydia cUBe Drosphila: Okay…yes that is a problem
How many culture bottles do you have now?
Please give the names of your culture bottles one by one with date of transfer of flies of that bottle + number of flies in that bottle (females, males, gravid)
[11:16 PM, 8/16/2021] Lydia cUBe Drosphila: Yes
I had a doubt❓
Tell me what you think
Can we call a plant that we study a model organism? Or would it be called a model system? Drosophila, Moina, mosquito, snails can be called model organisms, but what about Phyllanthus, Cardamine? What do you think? Will there be a difference in the terms model organism and model system in this case?
[11:23 PM, 8/16/2021] Lydia cUBe Drosphila: Does this happen all the time? If a change in the original structure of a protein occurs, is this change always irreversible?
[11:27 PM, 8/16/2021] Lydia cUBe Drosphila:
What if you keep a potato slice just like that without spreading the fermented coconut water on it? What do you expect? Do you plan to keep a potato slice as a control?

How many larval stages do your ants have @Seethalakshmy CUBE ?
[8:07 AM, 8/17/2021] Lakshmy PJ CUBE: Heteroblasty is the condition in which plants show a certain degree of variation among individual metamers during ontogeny. In some cases, however, there are abrupt and substantial changes in form and function (e. g. in leaf form, leaf size, phyllotaxy, internode length, anthocyanin pigmentation, rooting ability, or wood structure). These plants were called “heteroblastic” by Karl Goebel more than a century ago, but the functional significance of this type of ontogenetic change, the evolutionary trajectories in different plant groups, even their frequency in the plant kingdom are still unresolved issues. We argue that slow progress is partly due to an on-going terminological
confusion and the lack of distinction between other developmental processes such as ontogenetic drift.

[10:48 AM, 8/17/2021] Abhijeet Singh: So,
We actually did a year around mosquito project.
We were 8-10 students from 7-9th grade. We used to catch mosquito at our school together (before and after school hours) and at our homes by clap-trap method.
We used to collect the mosquito in a small container or box and the next day we put all that mosquitoes on a black paper. So that we can distinguish between Aedes and non-aedes ones(as aedes mosquito has white stripes on their legs)
We take the total count and and aedes mosquitoes number in that. We did this whole year with the hypothesis that we will fine more number of aedes in the late monsoon months(August to September end and initial weeks of October maybe)
Basic idea behind our hypothesis was that as after rain the mosquitoes will get more…

[11:32 AM, 8/17/2021] Aswathy Suresh CUBE:
[12:17 PM, 8/17/2021] Abhijeet Singh: Actually that’s great point to look into this more clearly!
I think that if we go definition wise…
In biology ‘system’ is something like a group of things working together to make stuff happen that helps in growth, nutrition and reproduction.
‘organism’ is any living structure, can be plant or fungi or bacteria capable of growth and reproduction.
Drosophila, Moina, mosquito, snails can be called model organisms, but what about Phyllanthus, Cardamine?
I haven’t categorised then into ‘model system and organism’ So if your trying to convey that they are seperate please let me know how and why do you think that!?
Can we call a plant that we study a model organism? Or would it be called a model system?
I think we can call it both . Plants have differe…

[12:45 PM, 8/17/2021] Abhijeet Singh: So why fermented coconut water is important @Aditiya Joshi CUBE .
What ingredients do yeast or bacteria or fungii need to grow?
What is the basic idea behind fermentation!?
[12:49 PM, 8/17/2021] Abhijeet Singh: Yeahhh I was also thinking about it!!
It would be great!
But proper understanding and references in this field is what we require before. Lets tune in Chatshaala for discuss on it!! @Lydia cUBe Drosphila @Aditiya Joshi CUBE @Saida Sayyed
[12:52 PM, 8/17/2021] Abhijeet Singh: With a brush or something it would be easy to pick them up and transfer!! @Batul Pipewala Kolkata
What do you think?
And also what are we studing in nematodes?
Can you give a context about it?
[1:21 PM, 8/17/2021] Aditiya Joshi CUBE: Actually, the traditional toddy is made from palm or coconut. There the juice/sap of palm/coconut flower. That is collected and fermented to give an alcoholic drink toddy.
About fermentation what I think is, the sugars like glucose will be converted to pyruvic acid. This pyruvic acid then will be converted into alcohol.
Yeasts/bacteria will require sugar or a carbon source, nitrogen source some ions like sodium, potassium, chloride, etc.
So, I think, the yeast/bacteria will utilise these nutrients and result in formation of alcohol.
I will try to observe the growth of these yeast/bacteria on a boiled potato slice.

[3:50 PM, 8/17/2021] Aswathy Suresh CUBE: Yes sir, this was one of the culture weak condition observed in last june month. It revived by the help of other collaborators @Arunan HBSCE sir @KIRAN CUBE mam @Batul Pipewala Kolkata mam @Aastha Ahuja Cube. Iam always thankful for that .
[3:52 PM, 8/17/2021] Arunan HBSCE: How do you expect to get eggs in this bottle? @Aswathy Suresh CUBE Please give your reasoning.
[3:58 PM, 8/17/2021] Arunan HBSCE: Are you not worried that there are no larvae, even after 5 days of transferring 14 flies of which 6 were gravid flies into this bottle?@Aswathy Suresh CUBE
Do you see some problem, again? @Aswathy Suresh CUBE Let’s discuss with every one.
[3:58 PM, 8/17/2021] Aswathy Suresh CUBE: Yes, I still keeping C subcultures bottles. but there is no flies, Larvae, Pupae in those bottles. Bottle where completely empty condition.

[4:10 PM, 8/17/2021] Aswathy Suresh CUBE: Imaginal disc is a sac-like epithelial structure found inside the larva of insects that undergo metamorphosis.
[4:10 PM, 8/17/2021] Aswathy Suresh CUBE: Larva turns into a pupa, almost all the larval tissues degenerate and the imaginal discs turn into the external structures of the head, thorax, limbs and genitalia.
[4:13 PM, 8/17/2021] Arunan HBSCE: Why do you think you missed it earlier?
A nice of Goof Up!
Was it because that was not part of the expectation?
What lessons can we learn and pass on to others from this, as vital lesson in Collaboration during establishing
CUBE HomeLabs! @Aswathy Suresh CUBE @Lydia cUBe Drosphila @Saida Sayyed @Aastha Ahuja Cube @KIRAN CUBE and others
[4:16 PM, 8/17/2021] Arunan HBSCE: What is the lesson in Collaboration from this we learn, as CUBE starts with Collaboratively? @Aswathy Suresh CUBE
[4:18 PM, 8/17/2021] Arunan HBSCE: Let’s highlight that lesson, for others to share their Daily Updates! @Aswathy Suresh CUBE
[4:21 PM, 8/17/2021] Arunan HBSCE: What one sees will be different from what collaborators see!
We have examples, every day!
So, please give photo evidence for your positive as well as negative observations & conclusions, for others to verify! @Aswathy Suresh CUBE
[4:23 PM, 8/17/2021] Arunan HBSCE: @Lydia cUBe Drosphila was asking for and it is good to give evidence @Aswathy Suresh CUBE Who knows, we may see some possibilities!
[4:29 PM, 8/17/2021] Arunan HBSCE: Wow! @Batul Pipewala Kolkata
What lessons from this for all Cubists?
Surely, @Aswathy Suresh CUBE and others like you and me could come up with this because Aswathy has been consistently keeping her HomeLab active and posting Reports with photos!
Another feather in Aswathy’s cap!
What lessons we learn from this? @Batul Pipewala Kolkata @Seethalakshmy CUBE and others
[4:30 PM, 8/17/2021] Arunan HBSCE: Let’s find out approximately how many? Is it according to the expectations? @Aswathy Suresh CUBE

And others
None that I can recollect. But are these Koel calls at your place consistent? or random outlier?
No Cuckoo calls heard in my locality at Kokar, Ranchi, Jharkhand.
[6:36 PM, 8/17/2021] Seethalakshmy CUBE: No @DP HBCSE sir, not regularly.
[6:37 PM, 8/17/2021] Seethalakshmy CUBE: Only in my area.
What about other places in Kerala
Ok, have the rains reduced in Kerala and weathered warmed a little? It could be some false alarm for that Koel. In Mumbai and I guess also in Ranchi, rains are still on…
Cuckoo calls heard a day before but when I was about to record it, it stopped😅
Yes, sir, it rained today as well as sunny.
[6:50 PM, 8/17/2021] Seethalakshmy CUBE: Ok, next time try to record the voice
[6:51 PM, 8/17/2021] Seethalakshmy CUBE: Ok! Is it rain there?
[6:55 PM, 8/17/2021] Seethalakshmy CUBE: Is there any connection between the rain and their calling?
yes. it rains daily in the second half of the day.

17th August 2021, 9.30pm to 18th August 2021, 9.30pm @Aswathy Suresh CUBE @Saida Sayyed @Abhijeet Singh @aashi.
Why finding mean is important? What’s the context of discussing mean in case of olfactometer? @Shraddha Sonavane CUBE we all remember your wonderful work that you have done on Phyllanthus recently.
Any follow up or update on your work?.
What does this whiteboard tells us?
What’s the Chai and Why? Session
[11:32 PM, 8/17/2021] Aswathy Suresh CUBE: @Isha Pawle please give your single line cultures of fruit flies in Worli - Mumbai
•How many Single Line Culture you made? When?
•Can you please tell the names of single line culture that you made.
•How did you trapped fruit flies?
Please give your current Home Lab Updates

•What is your further plan?
•Do you still facing any issues while trapping fruit flies?
Please give update from your Home Lab.
[11:46 PM, 8/17/2021] Aswathy Suresh CUBE: Understanding the confusion in understanding how to calculate mean (we should highlight some of such kind of instance in chai and why? session that we take for granted)…Collaboration, Communication, curiousity, context to curriculum and consistency.
[11:51 PM, 8/17/2021] Aswathy Suresh CUBE: Chai & Why
TIFR’s unique outreach initiative since 2009 has been the “Chai and Why?” series, a forum to enable informal discussions of interesting scientific issues outside a traditional academic setting in a Science Café format. http://univ.tifr.res.in/gs2021/Gallery/Images/022-Canteen.JPG
[12:28 AM, 8/18/2021] Seethalakshmy CUBE: I think the larvae not is visible at everytime. I didn’t much have idea about it, how can collect it’s larvae in the formicarium???
Please give some suggestions! @Batul Pipewala Kolkata ma’am, @Man Masih Beck RANCHI CUBE, @Arunan HBSCE sir, @Shrudhiga, @KIRAN CUBE ma’am, @Vishnupriya CUBE, @Aditiya Joshi CUBE, @Sunita Chahar CUBE ma’am and others…
[12:46 AM, 8/18/2021] Seethalakshmy CUBE: The gelatin dessert “Jello” gels due to the presence of a protein. When Jello is heated, its structure is altered so that it is no longer a gel but a liquid. If the denaturing conditions reversed by cooling in the refrigerator, the protein reforms into its original gel structure.
[12:47 AM, 8/18/2021] Seethalakshmy CUBE: Yes ma’am. This is a good idea! But how can collect their larvae in to the formicarium???
As well as how can feed them?
[12:51 AM, 8/18/2021] Seethalakshmy CUBE: Yes sir, that’s iam trying to say some of them are carrying inside the formicarium, as well as they carriying to out side the formicarium.
[12:51 AM, 8/18/2021] Seethalakshmy CUBE: Yes sir!
[12:56 AM, 8/18/2021] Seethalakshmy CUBE: Yes sir! That’s i want to find. Which species of ant these???
I need others help for identifying the Ant species.
Cubists can help me to overcome this problem.
This is a major problem that i faced my Model system.
Here iam stuck!
[12:58 AM, 8/18/2021] Seethalakshmy CUBE: Yes sir! Do all ants have same type of life cycle??
Please help me to find out Crazy Ant’s life cycle. @Batul Pipewala Kolkata ma’am, @KIRAN CUBE ma’am, @Man Masih Beck RANCHI CUBE, @Arunan HBSCE sir, @Aswathy Suresh CUBE, @Sunita Chahar CUBE ma’am, @Aditiya Joshi CUBE,@Lakshmy PJ CUBE…

What is imaginal disk??
Can you explain it??? @Aswathy Suresh CUBE, @Saida Sayyed, @Abhijeet Singh, @KIRAN CUBE ma’am and others
[1:04 AM, 8/18/2021] Seethalakshmy CUBE: My confusion is how can protien get refold??

After 24 hrs of fermentation. Left side bottle is open bottle. Right side bottle is closed bottle. Marked blue(left bottle/open) we can see a whitish layer formed. Marked Red(right bottle/closed) a thin whitish layer formed. Date:17/8/2021. Aditya Joshi. Kala Talav, Kalyan west
Small bubbles are seen in open bottle. Smells different from original coconut water. Somewhat smells like near bakery or smelly bread. 17/8/2021. Aditya Joshi. Kala Talav, Kalyan west. 24 hrs of fermentation
[11:07 AM, 8/18/2021] Seethalakshmy CUBE: So what is your interpretation?
[11:07 AM, 8/18/2021] Seethalakshmy CUBE: @Aditiya Joshi CUBE
Whitish layer in closed bottle after 48 hrs of fermentation. Aditya Joshi. Kala Talav Kalyan west. 18/8/2021
Only the open bottle shows bubbles?
Why the bubbles forms?
Bottle was swirled or shaken and then was tilted. The bus was dipped and then it was spread on potato slices. I used both hands. But to take picture, bottle was placed on ground n tilted.
18/8/2021. The fermented coconut water was spread on the boiled potato slices. Method: boiled potato slices were taken in a container with lid. A ear bud was used to take the fermented coconut water from the bottles. One bud for open bottle and one for closed bottle. The bud was dipped/soaked in the fermented coconut water. This bud was then spreaded on potato in S shape. Marked red are inoculated slices with open bottle coconut water. Marked blue are slices with closed bottle coconut water. Marked green are the non inoculated potato slices. Expectation: No colonies seen on non inoculated potato slices. Colonies should appear on inoculated slices. Date: 18/8/2021. Aditya Joshi. Kala Talav, Kalyan west.
[12:07 PM, 8/18/2021] Aditiya Joshi CUBE: I think these are the signs of fermentation
[12:08 PM, 8/18/2021] Aditiya Joshi CUBE: No. Some small bubbles were also in closed bottle.
Maybe these are of carbon dioxide released during fermentatiom
[12:08 PM, 8/18/2021] Aditiya Joshi CUBE: Fermentation*
Slices are kept in closed plastic box
See the point is that @Seethalakshmy CUBE that we are constantly trying explain the stuff that we are doing, in very basic and simpler terms and with examples and photos and references if possible.
Because people like me may not know what are clubed antenna . So it’ll get a hard way for me to get interested in your ants!!
What’s special about crazy ants!?
[1:30 PM, 8/18/2021] Abhijeet Singh: Great!!
I can see the legs of the ants are very shiny or whitish kind of. Is it because of the flash!?
[1:48 PM, 8/18/2021] Abhijeet Singh: We catch mosquitoes by clap trap method by making a hollow
in between both the hands, so that the mosquito is killed (but not smashed). We catch
only those mosquitoes that come to bite us in our house.
So this photo is from the presentation that we made for Cube National meet 2017 I guess(I’ll share that presentation shortly). We can see the white stripes easily on the Aedes mosquito with a black background. @Lydia cUBe Drosphila @Hina Mudgal Kanpur CUBE @KIRAN CUBE @Saida Sayyed @Aswathy Suresh CUBE VIDEO SHARED BY SEETHALAKSHMI AT 1.59AM

Update on Ant Model system…
They store sugars here.
Location : Pazhuvil.

Data collector : Seethalakshmi. C. R.
18th August 2021, 9.30pm to 19th August 2021, 9.30pm
Renamed the Cultures
In July 2020 , I had made 5 single line cultures. They were named as SLTT-A , SLTT-B, SLTT-C , SLTT-D and SLTT-E . After losing all these cultures , again started 2 new single line cultures in February 2021. To distinguish these cultures from 2020 cultures , named them as SLTT21-A and SLTT21- B. These two cultures lost in April 2021.
On 16 August 2021 , started 3 new single line cultures. And named them same as that of 2020 cultures. This will make confusions and affect the data of almost six months long single line cultures of 2020 which were also identified as of Drosophilidae family. I didn’t think this while naming. I thought that 2020 cultures are not existing and now I am starting the cultures after a gap of three and a half months.
In today’s chatshaala ,Arunan Sir asked me about this and made me understand the importance of nomenclature in research projects . Also I realised how valuable my old works and findings even when the cultures are not existing.
So , renamed all the single cultures of 2021 as a continuation of 2020 single line cultures. New names are :
SLTT - F ( SLTT21 - A) February
SLTT - G ( SLTT21 - B) February
SLTT - H 16 th August
SLTT - I 16 th August
SLTT - J 16 th August
@Arunan HBSCE Sir , @Lakshmy PJ CUBE , @KIRAN CUBE Ma’am , @Aswathy Suresh CUBE @Abhijeet Singh helped me in renaming and understanding the importance of nomenclature in projects. Thank you everyone.
Renamed the single line cultures of 16 th August 2021 as SLTT-H , SLTT-I , SLTT- J.

517 th day of CUBE ChatShaala: 18th August 2021.
19 CUBists from 19 Centres had joined the webinar.
Single Line Culture updates @Sidhy from from Thanniam - Thrissur Kerala, Restarted fruit flies works on 16-08-2021 made new single line cultures.
There is an issue while naming the cultures.Because last year July 2020 also started 5 cultures named SLTT A, B, C, D & E. But unfortunately she lost those all culture after 6 months later due to some other reasons (Goof ups)
Then February 2021 again restarted 2 single line cultures named SLTT 21A, SLTT 21B that’s also lost after 2month later.
August 2021, made 3 new single line cultures started with one mother flies naming again same that she added in pervious single line culture bottles.
Why Naming Is Important!?
Importance of Nomenclature.
Whatever work we are doing or done in at particular model systems that all works were recorded in here or somewhere. So all details are valuable even names also important factors that will help to identify.
Aashi from Haryana were joined yesterday chatshaala.
She want to addressing about how to study microbes from various corner of home. Eg : microbes on fridge handle.
Is there any effects of sunlight in microbes.?
Difference between sunlight and some other lights, how will effects microbes!
Why only sunlight get effects microbes?
Culture microbes at homes!
How can we culture microbes at homes.
What type of media will help to grow microbes?
Why can’t use POTATO slice for to isolate microbes.
@Aditiya Joshi CUBE Experiment isolating microbes from using coconut water.
Experiment details giving below
“18/8/2021. The fermented coconut water was spread on the boiled potato slices. Method: boiled potato slices were taken in a container with lid. A ear bud was used to take the fermented coconut water from the bottles. One bud for open bottle and one for closed bottle. The bud was dipped/soaked in the fermented coconut water. This bud was then spreaded on potato in S shape. Marked red are inoculated slices with open bottle coconut water. Marked blue are slices with closed bottle coconut water. Marked green are the non inoculated potato slices. Expectation: No colonies seen on non inoculated potato slices. Colonies should appear on inoculated slices. Date: 18/8/2021. Aditya Joshi.

17.08.2021 - Eggs ~30 , No Larvae, No Pupae
18.08.2021 - Eggs ~80 , 45 more larvae (Different stage) mostof them observed below the media side, 10 Pupae.
[11:55 AM, 8/19/2021] Aswathy Suresh CUBE: Expecting eggs inside the A22 culture. Because I transferred only one fly that reminded in A21 culture. Look like it is gravid one that’s why Iam expecting some eggs will laying that one fly inside in A22 culture.
[11:58 AM, 8/19/2021] Aswathy Suresh CUBE: Yes sir, I missed larvae inside E16 culture bottles. Because I am not much expected any larvae has remained after 1 month old bottles.
[11:59 AM, 8/19/2021] Aswathy Suresh CUBE: Collaboration through helping find out things that we can’t able see it but others can.
[11:59 AM, 8/19/2021] Arunan HBSCE: What is your expectations now, from tomorrow onward, in this bottle? That will help you to understand what is good or bad about your your culture conditions of Single Line E flies which were in very good shape so far.
Don’t you think so? @Aswathy Suresh CUBE
What are your comments @Yash Sheregare CUBE @Lydia cUBe Drosphila @Aastha Ahuja Cube @Batul Pipewala Kolkata and others
[12:01 PM, 8/19/2021] Arunan HBSCE: Why what is the basis for that? Is a culture of one month is too old? @Aswathy Suresh CUBE
What evidence we gave for that?
[12:04 PM, 8/19/2021] Arunan HBSCE: What is the best time (after how many days) to transfer flies for subculture from old bottles to fresh culture bottles? @Aswathy Suresh CUBE @Yash Sheregare CUBE @Aastha Ahuja Cube
[12:06 PM, 8/19/2021] Arunan HBSCE: if flies are thriving in
such bottles, don’t they mate and lay eggs and the eggs hatch to larvae? What makes you think that there can it be larvae?@Aswathy Suresh CUBE @Yash Sheregare CUBE
Is this not a nice Goof- up to celebrate so thate every one realizes that goof ups are common when we do research.
And such realization very important for progress in science! @Aswathy Suresh CUBE @Lydia cUBe Drosphila @Yash Sheregare CUBE @KIRAN CUBE

What about other plants?
Are they fruiting?
[12:51 PM, 8/19/2021] Aswathy Suresh CUBE: Not much old culture bottle is that.it Is just passed one month. Most of my observation after around one months bottles have less number of larvae. That’s why I mentioned I like that.
[12:51 PM, 8/19/2021] Aswathy Suresh CUBE: 20-25 is the Best time for to transfer flies in to new culture media bottles.
20-25 Days in normal situation (Good number of Larvae, Pupae, Adult flies).
But is there any emergency situation time come, don’t wait for that much time. immediately need to transfer those flies in new media bottle in order to save those flies.

Please comment on how do we stand to our claim that the ants we have are Black Crazy Ants too! @Seethalakshmy CUBE
Wow great @Shraddha Sonavane CUBE Does these fruits burst out?
Please keep it in closed container. Otherwise they will burst out and disperse seeds.
Yes I think that they look similar from the once you sent before!
I think 3 seeds in single capsule
Is that root hairs @Shraddha Sonavane CUBE
[1:26 PM, 8/19/2021] Lakshmy PJ CUBE: Which means they are fungus? @Shraddha Sonavane CUBE

Yes, kept it in closed container
[1:27 PM, 8/19/2021] Shraddha Sonavane CUBE: No @Lakshmy PJ CUBE .
There are on stem
Is it because of any Pest attack @Aditiya Joshi CUBE
[1:28 PM, 8/19/2021] Shraddha Sonavane CUBE: & on branches
[1:29 PM, 8/19/2021] Shraddha Sonavane CUBE: I don’t have any idea. I have to check
[1:31 PM, 8/19/2021] Shraddha Sonavane CUBE: Mam, is it because of white shiny threads like appearance?
Actually no insect or pest are seen on plant. Its producing new branches n sprouting new leaves… Flowers too… But no fruiting yet…
Can it be a mealybug infestation? @Shraddha Sonavane CUBE @Lakshmy PJ CUBE @Aditiya Joshi CUBE
I too had observed similar white structures on the Phyllanthus plant that I had brought from my building compound. And the leaves too had wilted out…that resulted in drying up of the whole plant.
Wooooooo A22 Bottle
That’s amazing this is your 23rd Bottle of A series. @Aswathy Suresh CUBE you have been doing a wonderful efforts.
But why this bottle is not fulfilling your expectations?
Wooow you got good number of Pupae but why flies are drying.
10 dead flies in 6 days
But there is no mealy bug attack on my Phyllanthus plants yet.
Nice photo with a nice background.
Is this an invasive species or local Cardamine of Mumbai?
What species of Cardamine this could be? @Shraddha Sonavane CUBE @Arunima SN Nattika Cardamine @Lakshmy PJ CUBE @Batul Pipewala Kolkata and other Cardamine collaborators.
How do we indentify the species of Cardamine?
I think we should check… it can be a possibility of fungi … because fungi can grown on dry & decay matter too.
What you think @Aditiya Joshi CUBE @Lakshmy PJ CUBE @Drishtant Cube Moina
Another Cardamine from another place of India.
Is this the munnar variety? Or plant brought from local plant nursery?
Which species of Cardamine this could be?
Wooowww another Cardamine but from which place of India? @Lakshmy PJ CUBE did you find them in your surroundings or you got these Cardamine from plant nursery?
What is the expectation? When do you expect to observe floral buds in these Cardamine plants?
If this is the case, then did @Aditiya Joshi CUBE observe the white structures on dried up plants or green, healthy Phyllanthus plants?
In how many days after the seed germination does this compound leaf has arises? What do you mean by transformation? Was this leave simple before?
Dried stems… dead plants @Drishtant Cube Moina
So, let’s rule out either of the possibilities that we have thought of; Fungi or mealybugs?
What do Fungi normally need to grow/sustain? The same question goes for mealybugs.
Any more inputs to add to the protagonists?
Absolutely sir!

@Lakshmy PJ CUBE @Shraddha Sonavane CUBE @Aditiya Joshi CUBE mentioned about Journey about when did started doing work in CUBE.
Cardamine Leaves stage study
Research Q : Floral dip method in Cardamine flowering bud.
Which leaves stage cardamine flowering bud will form in order to study floral dip method.
4-6 stages of leaves were showing flowering. Total 45 to 50 days taken for to get first floral bud in cardamine plants.
Gene Expression in Cardamine plants.
KNOX Genes : Compound leaves formation because of KNOX genes expression.
Simple leaves change in to compound leaves.
One of other Gene expression example is Moina. Body color change in White to Red. This condition called Hypoxia Condition. Happen in low oxygen levels (Unfavorable conditions)
What are the exact process of gene expression in cells ?
Before that we need to know what is Gene? Where can gene present inside nucleus!.
Tryingto find out this kind of fundamental questions answers through communication.!
Yesterday Discussion Based Reference Given in CHATBOX.
Analysis of circadian leaf movement rhythms in Arabidopsis thaliana Arabidopsis thaliana is the model organism for the study of the higher plant circadian clock. The physiological change in position of young leaves and cotyledons in Arabidopsis seedlings reveals an overt circadian rhythm. Analysis of circadian leaf movement rhythms in Arabidopsis thaliana - PubMed.
Although Arabidopsis lacks the pulvinus, it displays rhythms in cell elongation and, thus, in growth rate. For example, there is a circadian rhythm in the elongation rate of the abaxial and adaxial cells of the petiole that confers an oscillation in position of cotyledons and leaves (Engelmann and Johnsson, (1998)).circadian rhythm Arabidopsis - Google Search
Class I KNOTTED1-like homeobox (KNOX) proteins also promote leaflet initiation in C. hirsuta, and here we provide evidence that this action of KNOX proteins is contingent on the ability to organize auxin maxima via the PINFORMED1 (PIN1) auxin efflux transporter
Summary of CUBE Chatshaala (19/8/21)
We started discussion on Chai & Why session.
✓What is Chai & Why?
✓ Introduction of Chai & Why.
✓How to introduce all model systems.
So we started discussion on C.elegans & Phyllanthus.
In C.elegans model organism - we discussed how to connect Round worm in stomach with Nobel prize winning work & with Isolating of C.elegans on potato slices.
In Phyllanthus model organism - we discussed about how to connect Nobel prize winning work in fruit flies with Continuous light & dark experiment in Phyllanthus. also leaf angle titration connect with acid base titration.
Also highlighted on Phyllanthus niruri controversy.
[2:15 AM, 8/20/2021] Shraddha Sonavane CUBE: Today’s discussion was on 4 different plants -
1.Mimosa
2. Phyllanthus
3.Cardamine
4.Mango mapping
In Phyllanthus we discussed about @Lakshmy PJ CUBE’s story of Phyllanthus-
Initially @Lakshmy PJ CUBE was working on Mimosa plants for Circadian rhythm study.she also done seed germination study in Mimosa plant.
Then she working on Phyllanthus for Circadian rhythm study, Identification of Phyllanthus species,leaf angle titration.
Collaborators- @P. Chitralekha Cube JNU mam @Nidhi@Anushka Datta @ Anulekha @Shraddha
Then we discussed on my (Shraddha) story of Phyllanthus. I found some plants in plants pot at home.
I got interested because of Circadian rhythm study was in my MSc syllabus & because of observations done by @Harshad sir,in CUBE HBCSE.
[2:15 AM, 8/20/2021] Shraddha Sonavane CUBE: Great observations done by Susanta Tanti Sir & their students while returning to Assam from Mumbai by train.
They were observed how many Mango trees was flowering & then they mapped it.
Then we discussed on Cardamine plant-
• Lifecycle of Psyche butterflies on Cardamine plant were observed in G6 lab HBCSE.
• how many days required to get first flower buds?
• after how many Compound leaves first flower buds arose?
• why Cardamine having compound leaves & Arabidopsis having simple leaves?
Which genes responsible for leaf diversity in both?
•how do gene expressed?so we compare Cardamine- plant model organism with Moina
While understanding gene expression questions was arise-
1.what is a gene?
2.where it’s located inside the cell?
3.how gene expressed?
4.why Chromosomes are important in cell?
5.what is Chromosomes & Chromatin? @Seethalakshmy CUBE @Aswathy Suresh CUBE @Aditiya Joshi CUBE @Lakshmy PJ CUBE @Aastha Ahuja Cube @Mandar
It’s a caradamine? @Lakshmy PJ CUBE @Drishtant Cube Moina @Arunan HBSCE sir @Aditiya Joshi CUBE and others
How to identify caradamine ?
I think its oxalis… M not sure. But I thik its oxalis… This also grows as a weed in lawn, backyards, pots, gardens… @Janhvi Deshmukh
Yes I see in my area near the tulsi @Aditiya Joshi CUBE
Oxalis oxalis
Ohh @P. Chitralekha Cube JNU mam thanks mam
[10:13 AM, 8/20/2021] Arunan HBSCE: What is the question? @Shraddha Sonavane CUBE

Control set up please, to compare @Aditiya Joshi CUBE
Hope, you had set up Control. @Aditiya Joshi CUBE
Colonies appear after 48 hours of spreading fermented coconut water from closed bottle… Various colonies can be seen… Marked blue are similar colonies we have seen got by @Arunan HBSCE . We can also see multiple small circular cream color colonies. Some white colonies. And some mucoid or slimy colonies. 20/8/2021. Kala talav, Kalyan west. @KIRAN CUBE @Arunan HBSCE @Seethalakshmy CUBE @Aswathy Suresh CUBE @Lakshmy PJ CUBE @Batul Pipewala Kolkata @Saida Sayyed
Control slices got colonies too!!! They were not inoculated with the fermented coconut water. But growth can be seen… 20/8/2021. Kala Talav, Kalyan west.
[11:36 AM, 8/20/2021] Aditiya Joshi CUBE: The setup has turned smelly… The smell similar to spoilt bread/pav.
[11:37 AM, 8/20/2021] Aditiya Joshi CUBE: There were some fruitflies on the box. A small fly must have manages to go inside… As I opened the box, it flew away…
Observation of slices after 24 hours of inoculation with fermented coconut water from open bottle. We can see some growth or colonies seen. 19/8/2021. Kala Talav, Kalyan west.

[12:58 PM, 8/20/2021] Aditiya Joshi CUBE: No ma’am. It was not aur tight. A fly managed to enter it…
[12:59 PM, 8/20/2021] Aditiya Joshi CUBE: I kept control slices on open too… But within an hour, they were gone… I think some crows or rats might have taken away or eaten up
[1:27 PM, 8/20/2021] Aditiya Joshi CUBE: Possible goof ups n sources of errors…
The box and slices were kept open all the time while spreading the fermented coconut water. Spreading wad done very near or next to bottles kept.
No test slices were kept on open.
Control slices kept open were lost.
Flies were sitting at mouth and inside of open bottle. Also they were sitting on box, lid and one also managed to enter inside.
5.Though I have washed hands, knife, lid n box, there can be some microbes from these n air n by flies that might have settled on control slices.
I also opened it after 24hrs for clicking photos.
No sir, currently I don’t have any data!
I think we can start catching mosquito in our locality!
In collaboration with @Hina Mudgal Kanpur CUBE Ma’am @Seethalakshmy CUBE and others!
Hi All looking for collaboration on nematode study in the home lab, can you set up some raw potato slices with 4dtops of milk and soil to isolate nematodes and let them multiply on the potato.please reply you can ask questions if any
Okay ma’am I’d love to collaborate what is your plan
[1:41 PM, 8/20/2021] Ishita Assam: Plan of work
collect soil sample
potato slices to serve as medium
control and sample
4 drop of milk at the center to attract the nematodes
[1:42 PM, 8/20/2021] Ishita Assam: Ma’am when can I see the nematodes in the potato slice
What about water to keep set up moist?
From where will you collect soil sample?
Yes ma’am the soil sample will be damp and also I’d have to keep the potato slice moistened using a tissue paper at the bottom
After 24 to 48hrs of set up you should be able to see a small microbial pool on the potato slice and at the edges of this some worm like organisms 1 to 2mm in size moving
[1:44 PM, 8/20/2021] Ishita Assam: I’d have to collect from an area where there’s a lot of trees and where leaves fall and rot
[1:44 PM, 8/20/2021] Ishita Assam: Should I also cover it in case sone other insect lays in it?
Since C elegans has not been found in rotting leaves but has been found in rotting fruits or vegetables soil from such a place is advisable
Rotting fruits and vegetables, where can I get such soil then ma’am
[1:46 PM, 8/20/2021] Batul Pipewala Kolkata: Yes but not airtight otherwise a lot of fungus grows.Insect larvae are inevitable but nothing to worry they do not harm the nematodes as I have seen in my set ups
[1:48 PM, 8/20/2021] Batul Pipewala Kolkata: From under any Fruiting tree like jamun for example
Okay ma’am
Other nematodes will definitely be present in soil from other places@@Ishita Assam
[1:49 PM, 8/20/2021] Ishita Assam: I’ll update when I start this
[1:50 PM, 8/20/2021] Ishita Assam: Okay ma’am I will try and collect such but if I don’t I would continue with normal soil from garden and all
Why not we do a search for to see any colony morphology resemblance? @Aditiya Joshi CUBE
I’ll try too
Why not? “Ideally”, won’t we expect a sample of microbes from the atmosphere or knife used for slicing potato etc.? @Aditiya Joshi CUBE what is your plan?
Can’t it be the young ones! Any reference? @Batul Pipewala Kolkata
Was the photo taken intentionally not to have light on the full slices?@Aditiya Joshi CUBE
Yes sir. From knife, air, my hands
Control seems to show clear colonies. Any interpretation?
No sir. The shadow is of walls of box. N in flash light colonies were not seen much. It was shining. But yes, its opportunity for me to learn how to take better pictures n focus.
[2:01 PM, 8/20/2021] Arunan HBSCE: Let’s start! Don’t you think this rainy season may have resulted in a surge in mosquito breeding places and mosquitoes? @Abhijeet Singh
[2:03 PM, 8/20/2021] Arunan HBSCE: What is your guess? @Ishita Assam instead of we waiting for instructions! @Ishita Assam
[2:05 PM, 8/20/2021] Arunan HBSCE: Can’t we challenge this? @Ishita Assam
[2:05 PM, 8/20/2021] Arunan HBSCE: What if you do not cover it? @Ishita Assam
[2:07 PM, 8/20/2021] Arunan HBSCE: How about designing an experiment to challenge this? @Ishita Assam
[2:09 PM, 8/20/2021] Arunan HBSCE: Only trees? Why not under fruiting Phyllanthus plants and several others? @Ishita Assam @Batul Pipewala Kolkata
Any clear references?
I can collect soil samples from non fruiting area and an area where fruits fall and rot but then the thing is I won’t be sure if I’ll get C.elegans or not
Why not post the full Design now itself, after stating the objective?@Ishita Assam
Sir last time I got larvae in my potato slice
Could not follow y you wont be sure if it is C elegans?Is it because you need a microscope to see their features@@Ishita Assam ?
[2:13 PM, 8/20/2021] Arunan HBSCE: Why not do both, with a clear design starting from now? @Ishita Assam @Batul Pipewala Kolkata
[2:13 PM, 8/20/2021] Arunan HBSCE: Design, please @Aditiya Joshi CUBE
Yes sir I can design an experiment
[2:16 PM, 8/20/2021] Arunan HBSCE: Please post those evidences @Ishita Assam Please give a summary and state where you got stuck?
How are you going troubleshoot, this time? @Ishita Assam
[2:17 PM, 8/20/2021] Arunan HBSCE: Let’s start! @Ishita Assam
Yes sir
What could be your research question in soil Nematodes? @Ishita Assam

519 th day of CUBE ChatShaala: 20th August 2021.
Note: Cubist(s) who had joined today but their name isn’t included in the list, kindly replied to this message[12:26 AM, 8/21/2021] Shraddha Sonavane CUBE: Cardamine- Psyche butterflies interaction
Cardamine is new host plant for Psyche butterflies.
While working on Cardamine model organism in January 2020, initially I was observed one Caterpillar on Cardamine plant:seedling: in 2nd right side patch of Cardamine forest in front of HBCSE main building.
I was curious about caterpillar so I was collected caterpillar with same Cardamine plant on which caterpillar found.
I kept same plant in container having some water so all roots dipped inside Water.
Then,This container & some more Cardamine plants were added in another container. both containers were kept in glass tank.
One Open side of glass tank was tightly covered with net & rubber band.
After 4-5 days I observed Caterpillar was turned into green pupa.In between 4-5 days, I observed that Caterpillar was eaten most of leaves & fecal matter was there.
After 5-6 days, new adult white butterfly with prominent black spot on upper wing was emerged.
Because of their appearance I could easily found that their name - Oriental Psyche (Leptosia nina nina)
[12:27 AM, 8/21/2021] Shraddha Sonavane CUBE: Because of more observations I could found one Egg & 6 more Caterpillars on Cardamine plants
The Egg was cylindrical shape & white in colour on terminal leaflet in upright standing manner.
Again Similar set up were made to study life cycle of newly found Caterpillars.
In these set up I could observed 2 different pupa colour- 1 green colour &
2. Yellowish brown/Creamish colour.
But when adult butterflies emerged, I could observe
2 different eyes👀 colour- 1.Brown colour
2.green colour
Summary of 519th day of Cube Chatshaala*
We started the discussion with what I(Abhijeet) have plan for the Chai and Why? Programme.
So I’ve worked on Model Organisms like Mosquito, Earthworm, and Snails when I was active in cube in my secondary school (7th to 9th std)
So today we discussed about Earthworm.
How can we culture and maintain Earthworms in our Homelab?
So culturing earthworms at home would be very easy! We don’t need high-tech laboratory stuff. We just need a plastic cup, paper, earthworm and waste cloth
Take cup and pinch holes at bottom with the help of a pin.
Make pieces of paper, and fill 1/3rd of the cup.
Make that paper inside cup moist with water
Put earthworm inside cup.
Cover the cup with cloth and rubber band.
keep the cup(s) inside a tray with newspaper wetted with enough water .What’s special in Earthworms?
Humans have Spinal cord which helps in making co-ordination between different body parts in each activity that we do throughout. If due to some reason the spinal cord is injured we get paralyzed and the co-ordination is lost.
Earthworms have Ventral Nerve Cord(VNC) with same function as Spinal cord in humans i.e maintaining coordination in body. But if VNC of earthworms get injured it gets regenerated
So can we study how this regeneration happens in earthworms but not in humans!!!
RAPID ESCAPE RESPONSE TEST (RER) was designed to see how in how much time this regeneration of VNC occurs and also for selecting earthworms with good co-ordination in their body.
How is RER test performed!?
Make salt solution of a particular concentration.
put some 2-5 ml of that in test-tube(experiment)
3)take another test-tube fill with 2-5ml of water(control)
add one earthworm at a time in both and watch their response within the 2 min time
note the observation.
Remove the earthworm from soln and wash is very nicely and keep the back in culture
Expectations:-
The earthworm should immediately response towards the salt solution and escape from it.
Inference:-
As the salt solution is harmful for earthworms they should escape from it showing excellent co-ordination. And earthworm in water(control) would not show any response towards water.
Earthworm which showed the coordination and came out of salt solution can be selected for studying.
After RER test we can use the earthworm that passed the test for studying the time it takes for them to regenerate their VNC.
On the ventral part we give a lesion(enough that we can say that VNC is lesioned).
After giving the lesion perform the RER test to confirm that earthworm’s body co-ordination is lost.
Expectations:- The earthworm should not be able to escape the salt solution.
Continue doing RER test with 2 days interval till the VNC is regenerated and the co-ordination is gained again.
@Aswathy Suresh CUBE can you please comment on how can we perform RER in our homelabs! @Aditiya Joshi CUBE @Seethalakshmy CUBE please comment on the nutrition that can be derived by earthworm by eating paper in cup cultures!!!When I (Shraddha) & @KIRAN CUBE mam did search on Leptosia nina - Wikipedia & https://www.ifoundbutterflies.org/sp/811/Leptosia-nina/early-stages
for host plants of Psyche butterflies, we found that Cleome,Capparis are host plants but not Cardamine plants
21st August 2021, 9.30pm to 22nd August 2021, 9.30pm
But I got complete life cycle of Psyche butterflies on Cardamine plants.
So we did survey in whole HBCSE campus for Cleome or Capparis & for Cardamine plants
& we get only 3 Cleome plants in whole Campus (at besides G6 lab, near BARC Compound ), whereas we observed huge Cardamine forest (more than 1000 plants) in whole Campus. (Mostly at sorrounding to main HBCSE building)
So it was like ecological survey of 3 different plants in HBCSE campus.
So, Questions came in mind-
✓Cleome & Capparis are belongs to Cleomaceae & Capparaceae family resp.
✓Cardamine belongs to Brassicaceae/ Cruciferae family.
1.why female Psyche butterflies laid egg on Cardamine plants?
✓we get an answer that all 3 families are different but they having common origin meaning they are belonging to same Order - Brassicales
The characteristics of Brassicales order is they are rich source of secondary metabolites i.e.glucosinolates
Hence in all 3 plant families members, Glucosinolates is present.
because of more number of Cardamine plants compare to Cleome/Capparis plants in a Campus so for survive female Psyche butterflies choose Cardamine plants for egg laying.
All observations done in HBCSE campus.

The size of leaves of Cleome and Capparis can also be one of the factor Shraddha
Plant kept in LED for one month and shifted to normal conditions,shows delayed opening of leaves
Plant s under normal conditions
[8:40 AM, 8/21/2021] Shraddha Sonavane CUBE: Thank you @Ankit Yadav Xms Work Shop Cube Patkar College
Yes. Glucosinolates help in identification of host plants & as you said it also help in protection of next generations.
It means female butterflies not only select food for next generations but also protect themselves from microbial infections and other predators attacks.
Glucosinolates are slightly bitter in taste so, many organism not prefer glucosinolates containg food.
this is winning situation:partying_face: for Psyche butterflies.
Because less competition for food and When Caterpillar eat these glucosinolates containg food it might chances that in their guts some amount of glucosinolates present so probably less chance of predators attacks.
[8:45 AM, 8/21/2021] Shraddha Sonavane CUBE: Sorry mam I didn’t get.
But You mean size of leaves of Cleome & Capparis is larger than Cardamine is it? @Sunita Chahar CUBE mam
[8:53 AM, 8/21/2021] Shraddha Sonavane CUBE: Congratulations @Sunita Chahar CUBE mam
plant are still surviving in stress conditions for more than one month.
[8:53 AM, 8/21/2021] Shraddha Sonavane CUBE: How many minutes/hours of delayed?
What’s leaves opening time in Control plants and in shifted plant?
I could see some white cottony structure on branches. What are they?
Is it mealy bug attack or something else?
[9:17 AM, 8/21/2021] Abhijeet Singh: Okay, this was new for me!!!
Does butterfly actually select the plant to lay eggs? @Shraddha Sonavane CUBE @KIRAN CUBE

There is one major difference between Starch and Cellulose.
For starch, glucose repeat units are located in the same direction, and each successive glucose unit is rotated 180 degrees in cellulose.
Cellulose is thicker than sugar, which is water-insoluble. On the other hand, the Starch is less weak than cellulose and can be dissolved in warm water.

Let’s all learn together. @Seethalakshmy CUBE
Cellulose is a linear polymer and starch is consist of linear and branches. These arrangement do effect the properties.
The reason is due to the different types of bonding between cellulose and starch. Cellulose has beta-1,4 bonds that are not digested by our enzymes (which can digest alfa-1,4 and alfa-1,6 bonds that are present in starch and glycogen). However, some bacteria from the gastrointestinal tract of human and other animal species can use cellulose as an energy source since they are able to break the beta 1,4 bonds. Actually, that is one of the concepts of fiber (carbohydrates that are not digested by the enzymes produced by the animal, being fermented by bacteria).
The arrangement of the glucose units in starch also differs between amylose (linear structure with alfa-1,4 bonds) and amylopectin (branched structure with alfa-1,6 bonds), explaining the differences in glucose absorption between ingredients with different proportions of these two polymers.

Okay
Any update on this now?
Nice!
How do you make sure that there are still new flies emerging in this bottle?
What are your plans with these cultures?
[3:27 PM, 8/21/2021] Lydia cUBe Drosphila: This is not that old bottle. How long does a culture bottle survive on average?
And what could be the reason for the death of so many flies? What do you think?
[3:31 PM, 8/21/2021] Lydia cUBe Drosphila: Yes understood
Why not explain using some examples? Some relevant examples of proteins…a protein that can reverse back to the original structure and another protein that is irreversible…a comparison kind of.
By this, we’ll always remember such examples.
[3:33 PM, 8/21/2021] Lydia cUBe Drosphila: How does a non-clubbed antenna look?
Can you please send some pictures of the ants with these characteristics that you think are morphological features.
Within 5 days, 10 flies dead!
Were those flies too old when you transferred?
[3:36 PM, 8/21/2021] Lydia cUBe Drosphila: What’s the difference between these 2 kinds of ants?
[3:39 PM, 8/21/2021] Lydia cUBe Drosphila: Are those white stripes on aedes mosquitoes legs quite visible?
[3:44 PM, 8/21/2021] Lydia cUBe Drosphila: True!
Got it
I got some doubts from some of my friends… I wasn’t able to convince them completely w.r.t. organism and system…so thought of asking.
Thank you!
[3:44 PM, 8/21/2021] Lydia cUBe Drosphila: Yes exactly!
We’ll get a context to get to know more on these curriculum topics!
[3:52 PM, 8/21/2021] Lydia cUBe Drosphila: Egg yolk too contains proteins right?
So same is the case for both egg whites and egg yolk…right?
[3:55 PM, 8/21/2021] Lydia cUBe Drosphila: Would the presence of fats interfere with the protein denaturation process?
[3:59 PM, 8/21/2021] Lydia cUBe Drosphila: Yes Sir!
True!
A healthy culture bottle will give us all the stages of a fruit fly! We do expect to see eggs, larvae, pupae and adult flies!
More interested to see the larva, as an indicator that fertilized eggs hatch to larvae.
Please post larvae of SLBK A22.

Summary of 520th day of Cube Chatshaala
Discussion started with @batul Ma’am’s nematodes culturing and identification.
Currently batul Ma’am culturing nematodes on potato slices. With that she is trying to identify C.elegans from her nematodes if there’s any in her culture!
Identification:-
So for identification of C.elegans she is using a photo of C.elegans from a research paper(The Pharynx of Caenorhabditis elegans Albertson 1975) and compare the morphological characteristics with the nematodes that she has cultured in her homelab!
Identification so far:-
So far she is able to compare the Anterior part(i.e. pharynx).
After that discussion went on about the speculation and casual observation that we make in our experiments and our interpretation of that! With reference to Aswathy saw Nematodes after 15days in her drosophila TRSV media which has vinegar and Batul Ma’am is not able to culture nematodes with RSV media with has Vinegar.
A very important point that came after discussion is that:-
Speculation, Casual observation is always welcomed!! but it is to be verified with evidence and experimental design with enough replicates and control
This leads us to the very fundamental idea of CUBE and ofcourse of science is:- CONSTRUCTION AND NOT INSTRUCTION
This knowledge construction can be through 2 types of collaborators:- 1)Involved in Discussion 2)Working on same model organism
Moving forward with Discussion on Circadian Rhythm and understanding it properly. A circadian rhythm or circadian cycle, is a natural, biological process that regulates and repeats roughly every 24 hours. … The term circadian comes from the Latin circa, meaning “around” (or “approximately”), and diēm, meaning “day”.(example:- opening and closing patter of leafs in phyllanthus)
Also Circannual Rhythm. The term circannual is Latin, circa meaning approximately and annual relating to one year.(example mango flowering)
Moving forward with discussing the CIRCADIAN RHYTHM with respect to stomatal opening and closing in plant’s leafs and photosynthesis process(with context to secondary school biology curriculum) .
AND
CIRCANNUAL RHYTHM with respect to mango Flowering and Fruiting pattern throughout India.
3days after inoculation of fermented water. Slices in red marked outline are inoculated with fermented coconut water from closed bottle. White cottony colonies, Greenish n blackish colonies are seen. Also, circular whitish colonies can be seen too. Also few small thread like colonies too. Marked blue are slices inoculated with fermented coconut water from open bottle. Thread like colonies are seen. Also blackish n white cottony growth are seen… Thread like colonies are seen on control slices. The color of these thread like colonies is seen to be changed. 21/8/2021. Kala Talav, Kalyan west.
There is a nasty smell… Strong smell similar to that of spoilt bread… There were some small flies too
[7:28 AM, 8/22/2021] Abhijeet Singh: How this chemoreceptors help them! @Shraddha Sonavane CUBE
Please elaborate!
[7:39 AM, 8/22/2021] Abhijeet Singh: I think sir! Because we have seen earthworm surving on paper for a complete year!
Humans cannot digest Cellulose and that us why I think we cook our vegetables and then eat!
But earthworm can digest it and survive it.
So cellulose can be the source of nutrition for earthworms to survive!
[7:39 AM, 8/22/2021] Abhijeet Singh: What do you think @Aswathy Suresh CUBE @Aditiya Joshi CUBE @Ishita Assam and others!!?
[7:44 AM, 8/22/2021] Abhijeet Singh: Yes Yes! That’s is very interesting thing sir! I would like to tell this to everyone that, in cube lab, we had a one year old cup culture. Same tissue paper was given to earthworms to feed on. The the tissue paper in the cup was eaten and again eaten and again since one year! So we can literally see that the paper had become very similar to what soil looks like!
I’ll look for photographs from collaborators if I can get I’ll post it in the group!

Picture is not much clear, But we can able to see the mouth hook part of this larvae is not much fully developed. 2 black sports kind thing can see at anterior portion. Spiracles is not present at the tip of body. that’s why I concluded this is first instar larvae of fruit flies
[11:32 AM, 8/22/2021] Aswathy Suresh CUBE: Yesterday discussed about Mango flowering in different parts of country based on Latitude & Longitude. Is there any significants chances we can able to see in mango flowering from lower to higher latitude (N) regions.

One more thing…after inoculating these potato slices, where did you keep them? And for how long?
[1:43 PM, 8/22/2021] Lydia cUBe Drosphila: In what all is cellulose present other than paper?

So why not send us your plan in detail.
Tell us, larvae from which culture bottle you are preferring…details of that culture bottle.
Send us your detailed plan for the olfactory assay and of the culture bottles that you’re going to use.
[1:49 PM, 8/22/2021] Lydia cUBe Drosphila: So what’s the story of the B20 bottle? From where did you transfer the flies into B20?
~20 days old flies are not that old, right @Aswathy Suresh CUBE?
Also, what’s the lifespan of a fruit fly? How long can a fruit fly live?
[1:52 PM, 8/22/2021] Lydia cUBe Drosphila: Nice!
Please send pictures of the 3 stages of fruit fly larvae, where we can clearly distinguish between the stages. It will be helpful for you as well as for others.
Also, what are the main features or characteristics that you look for in a larva to identify its stage?
Look for the tiny external head, three thoracic segments, eight abdominal segments, and a telson
extending beyond the anus. These segments are delineated by ventral rows of tiny hooks, denticle
belts, which prevent the larva from slipping backward as it moves forward with waves of extension
and contraction. You should also see a number of sensory bristles in the first instar larva distributed
over the cuticle.
[2:43 PM, 8/22/2021] Shraddha Sonavane CUBE: Sir, I only remembered about @Arunima’s work.she had observed Psyche butterflies larvae in her home lab during lockdown. But I don’t know exactly what was work done by Drishya.

Published: 15 November 2011 https://doi.org/10.1038/ncomms1548
Female butterflies lay eggs on their host only when they detect specific chemicals through their foreleg chemosensilla while drumming on the leaf surface. Here we show that the butterfly, Papilio xuthus, uses a gustatory receptor specific for synephrine to select its host in oviposition behaviour. @Shraddha Sonavane CUBE Please coordinate with @Arunima SN Nattika Cardamine to tell us more about Cardamine- Psyche butterfly interaction. @Shraddha Sonavane CUBE
ALERT:- From last year’s data collected by Cubists, we are having a Hypothesis that Mango Flowering start from south Kerala and
Hence, collecting data of what mango trees does now onward is very useful to test the Hypothesis of Cubists.
All cubist are hereby requested to look around for MANGO FLOWERING in their locality and send pictures Of mango tree with NAME OF DATA COLLECTOR, NAME OF LOCALITY LAB, DATE, TIME, LONGITUDE AND LATITUDE, and MINIMUM AND MAXIMUM TEMPERATURE.
Crucial time for Mango Mapping!!
Looking forward for collaboration from all cubists across India!
Comparing with diagrams too there are two bulb like structures in my nematode instead of swollen pharynx please see the whole video

[11:38 PM, 8/22/2021] Aswathy Suresh CUBE: Hypothesis is that lower latitude going upper latitude region there is kind of difference can able see in mango flowering. Based on last year observation came from Thiruvananthapuram - Kerala, 8.5241° N part mango started flowering on september last week onwards. Thrissur - Kerela 10.5276° N started mango flowering observed on October last weeks onwards. Going to upper part like Mumbai 19.0760° N - November/December , Kolkata 22.5726° N its taking December/January (If iam wrong please correct it). This is a kind of pattern is repeating or not in every year (Circannual Rhythm) this is we are addressing questions. We need to check this throughout collecting data from different parts of country.
[11:50 PM, 8/22/2021] Aswathy Suresh CUBE: Kanyakumari is 8.0883° N, 77.5385° E.
Trivandrum is 8.5241° N, 76.9366° E
Kanyakumari & Trivandrum are 8N away from equator (0N). But there is not much drastic change can’t able to see between these of them 8.0N - 8.5N.
Prediction : Kanakumari mango flowering expecting in first week of September onwards. In Trivandrum - mango flowering expecting in last week of September.
Nice picture We can able to see some Fruit flies present inside the Guava fruit.
Yes sir! We can search for wet places. Earthworms mostly found in nutrient black soil.
Awesome .
Why fruit flies are attracted towards cloth ? Because of smell of yeast ? What are they doing on clothes ?
[12:05 AM, 8/23/2021] Seethalakshmy CUBE: Yes sir! For culturing them cellulose as well as water is enough
[12:07 AM, 8/23/2021] Seethalakshmy CUBE: Sry sir! I didn’t get the question
[12:09 AM, 8/23/2021] Seethalakshmy CUBE: common name: crazy ant
scientific name: Paratrechina longicornis (Latreille) (Insecta: Hymenoptera: Formicidae)
https://entnemdept.ufl.edu/creatures/urban/ants/crazy_ant.htm
The crazy ant is so morphologically distinctive that it is one of the few Paratrechina that is not consistently misidentified in collections (Trager 1984). The crazy ant worker is relatively small (2.3-3 mm). The head, thorax, petiole, and gaster are dark brown to blackish (Creighton, 1950); the body often has faint bluish iridescence. The body has long, coarse, scattered, suberect to erect, grayish or whitish setae (hair-like projections).
And also their rapid movement as well as white bands
Yes we needs more improvement for identifying the genus and species level.
As well as we needs to study it’s morphology

[12:36 AM, 8/23/2021] Aswathy Suresh CUBE: Life Span of Drosophila 70 Days - 90 Days.
[12:37 AM, 8/23/2021] Aswathy Suresh CUBE: A typical, healthy and well-maintained outbred Drosophila population will have a median lifespan of approximately 70 days and maximum of approximately 90 days at 25 °C. At a more detailed level of physiological decline, numerous markers of ageing-related loss of function can be observed.

[12:05 PM, 8/23/2021] Abhijeet Singh: Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and rayon.
Cellulose for industrial use is mainly obtained from wood pulp and cotton.
Some animals, particularly ruminants and termites, can digest cellulose with the help of symbiotic micro-organisms that live in their guts, such as Trichonympha. In human nutrition, cellulose is a non-digestible constituent of insoluble dietary fiber, acting as a hydrophilic bulking agent for feces and potentially aiding in defecation.

Sir I’m expecting flowering to start by September.
I’ll keep getting updates and I’ll add the observation in the given link!!
This is my expecting from one gravid fly that transferred from A21 to A22 after 9th day.
One gravid fly lay 50 eggs per day (Referance says) . In this calculation we will get 450 eggs on 9th day. Also get ~50-60 progeny’s get in 9th days.
But usual observation eggs are present inside cultures ~20-40 is maximum can able see but it fertilized or have not no idea because Larvae present in culture very less.[3:07 PM, 8/23/2021] Aswathy Suresh CUBE: Yes @Yash Sheregare CUBE, Eggs Can able to see inside the culture ~20-40, But larvae are very less present culture. Only 3 larvae I can able to see inside culture.

Mushrooms also have a similar structure. Do their heads also have spores? Or am I completely off?
[8:59 AM, 8/24/2021] Arunan HBSCE: Can we get a longer shot where this set up is placed? @Batul Pipewala Kolkata
[9:07 AM, 8/24/2021] Arunan HBSCE: " This nematode is particularly abundant in microbe-rich environments, especially rotting plant matter such as decomposing fruits and stems. In this environment, it is part of a complex interaction network, which is particularly shaped by a species-rich microbial community. These microbes can be food, part of a beneficial gut microbiome, parasites and pathogens, and possibly competitors. C. elegans is additionally confronted with predators; it interacts with vector organisms that facilitate dispersal to new habitats, and also with competitors for similar food environments"

[11:50 PM, 8/25/2021] Lydia cUBe Drosphila: That’s true
You have a mixed culture of young and old flies
Do you think you can plan something to find out how long fruit flies can live/their lifespan? What say?
Do you think knowing the lifespan of fruit flies is important?
[11:54 PM, 8/25/2021] Lydia cUBe Drosphila: Okay!
B19 indicates that this is the 19th culture bottle of single line B…right?
So you had B1, B2 and so on and now till B21…right? B1 started with 1 gravid fly…
And then their progenies are being transferred into the further culture bottles…right?
Just correct if I’m wrong anywhere
What happened to the initial culture bottles of single line B? Do you have any or do you only have the cultures B19, B20 and B21?

Understood!
What is your objective with these mosquitoes?
(I’m sorry if I missed out on this too in the previous messages…not able to keep a track of all the messages these days)
Interesting!
A twist in the conversation! Which microorganisms live in the guts of ruminants? Maybe an example can help!
Also, can these microorganisms be used as cellulose digesters for some bio-based aspects or experiments ?
What do you think? Even I don’t know about this…I was just wondering about this while reading your message
Do we consume any food that has cellulose in it?
Green beans were highest in cellulose and hemicellulose
We do consume some of these foods often. What do you think? How do we digest or consume these foods even though we don’t have the ability to do so? Won’t this be a problem ?
What do you think could be a reason for the death of fruit flies @Yash Sheregare CUBE? Even @Aswathy Suresh CUBE is facing the same issue.
[12:19 AM, 8/26/2021] Lydia cUBe Drosphila: These are working well @Yash Sheregare CUBE
SLPbB2 and SLPbC2 cultures
Then why is SLPbA2 having an issue?
[12:23 AM, 8/26/2021] Lydia cUBe Drosphila: This is good news! @Aswathy Suresh CUBE
Hoping to see and get more updates on this new A22 culture bottle
[12:25 AM, 8/26/2021] Lydia cUBe Drosphila: I think cardamine is a host plant for one butterfly species, right @Shraddha Sonavane CUBE?
That way we can connect I guess.
[12:27 AM, 8/26/2021] Lydia cUBe Drosphila: Yes
Life cycle of different model organisms can be connected…this comes under the curriculum topic, developmental biology
Yes @Lydia cUBe Drosphila, We can connect through butterfly Cardamine interactions.
Because Cardamine is host plants of Psyche butterflies.

What is your further plan? @Yash Sheregare CUBE Please post a few good photos to show your HomeLab set up with Location and Date @Yash Sheregare CUBE
Ants release pheromones through which they communicate to fellow ants. That’s why ants move in a line…after one another.
During our childhood, we
used to disturb their sequence by moving fingers arround them. Ants used to disperse around and then again form a line.
Later on found out that we were dispersing the pheromones…disturbing their moving pattern…
It’s a very interesting phenomenon…
[9:56 AM, 8/26/2021] Arunan HBSCE: How about keeping a slide like this to show the extent of collaboration and a glimpse of concept map that all cubists work together, from across the country, to all at the end of Chai& Why? session, today?

We need to design a plan in order to find the life span of fruit flies - culture bottles ma’am.Here’s the short video of my fruit fly home lab.
From Worli, Mumbai.[10:42 AM, 8/26/2021] Aswathy Suresh CUBE: Definitely it’s important. Because Current situation facing major issue is flies dying in culture without any reason.we need to find out the answer. Before that we have to know how many days flies will alive (Life span)
[10:57 AM, 8/26/2021] Aswathy Suresh CUBE: Yes, B Line started on 26th May 2020 during the pandemic started time. started B line culture with 1 mother fly, trapped using tomato bait. Culture named SLBK B. Starting from there after several subculture passed B1,B2,B3,B4…B19, B20, B21 (subcultures) . Every months transferring all progeny’s from old media bottle to new media bottle in order to maintain that line culture. Last made subculture is SLBK B21 , Currently I have SLBK B18, B19, B20, B21 subculture bottles. But only B21 bottles have Larvae, Pupae, Adult Flies. Old bottles were taken for making new subcultures…cleaned and reused for making further subcultures (Because of unavailability of bottles).
[11:02 AM, 8/26/2021] Aswathy Suresh CUBE: I don’t have B subculture bottle which I started on 26/05/2020.That bottle were remained after 1 and half month. After that I taken that bottle and cleaned reused for making further subcultures.
Currently I have only B21 (Date of bottle : 12.08.2021) which have flies,larvae, pupae.
[11:03 AM, 8/26/2021] Aswathy Suresh CUBE: B Line

Hello I am Binita. In June 2017 two months after returning back from HBCSE, I started first Kitchen lab. Undergraduate research is not yet popular in Jharkhand, so except @Dr. G C Baskey Cube Ranchi and @Shalini CUBE Rachi people were skeptical about undergraduate research. I wanted to check the hypothesis so I convinced my parents and family members. A space was needed for other people to discuss and perform science, we did several experiments in this space. 10 months after the lab started we got a space in college. If you ever thing that you are not able to do science because of some problem, then I am sure the problem in your head. Also I strongly believe that places and surrounding should not decide how fit we are for doing what we want to do. I got a chance to work in CCMB for master’s thesis in Dr. Rakesh Mishra’s lab. Currently I am taking a reading break, applying for PhD and running a VIRTUAL KITCHEN LAB. The idea is to gather people to share their journey in science. I hope you all will enjoy watching these videos. https://www.youtube.com/channel/UCXwh1LampcQbILWhqNmrynw There are some amazing videos that are coming up soon. https://www.youtube.com/channel/UCXwh1LampcQbILWhqNmrynw

How will Aditya isolate and characterize Yeast from fermented Coconut water?
Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized.[1][2][3] They are estimated to constitute 1% of all described fungal species.[4]
Yeasts are unicellular organisms that evolved from multicellular ancestors,[5] Yeast - Wikipedia
Saccharomyces cerevisiae which is also known by its common name brewer yeast or baker yeast.

Environmental and Genetic Determinants of Colony Morphology in Yeast Environmental and Genetic Determinants of Colony Morphology in Yeast
Baker’s yeast forms smooth round colonies when grown in favorable conditions. When starved for one or more nutrients, yeast can alter its growth pattern to produce complex structures consisting of numerous interacting cells. One mode of growth, the colony morphology response, produces visually striking, lacy colony architectures.

Nematode populations
We isolated 38 new strains of C. elegans and 25 new strains of C. briggsae from single wild hermaphrodites in Kenya and South Africa in March–April 2006. Despite extensive sampling from 36 sites, Caenorhabditis nematodes were only found in four locations: (1) compost from a private garden (Johannesburg, South Africa); (2) compost from a plant nursery (Ceres, South Africa); (3) compost from a mushroom farm (Limuru, Kenya) and (4) leaf litter in a public park (Nairobi, Kenya). Strain name designations for C. elegans are ED3040–ED3077, and for C. briggsae are ED3078–ED3102. The sampling sites and strain designations are described in Table 1. Various other nematode species were also found in these sites, including many strains of Oscheius tipulae, which have also been characterized (Baïlle et al., 2008).

[11:02 AM, 8/28/2021] Arunan HBSCE: “As a model organism, the nematode Caenorhabditis elegans has provided an outstanding system for elucidating fundamental problems in biology. However, the attitude regarding the natural history and ecology of Caenorhabditis has long been ‘hakuna matata’, to use the Swahili phrase meaning ‘no worries’. To achieve a robust understanding of the evolutionary context in which C. elegans’ developmental and genetic patterns emerged, it is necessary to characterize representative natural populations on a worldwide scale and to conduct comparative analyses of Caenorhabditis species.” https://www.nature.com/articles/6801079#:~:text=As%20a%20model,of%20Caenorhabditis%20species.

[12:13 PM, 8/28/2021] Batul Pipewala Kolkata: Article by Marie Ann Felix
[12:35 PM, 8/28/2021] Batul Pipewala Kolkata: Outstanding questions about the natural history of C. elegans.
What is the pattern of C. elegans migration at different geographical distances? What are the relevant vectors? Are humans now major vectors over large scales?
Over a small scale, ongoing local population surveys will provide insights into migration patterns. Over large scales, selective sweeps estimated to date from 100–200 years ago have spread to different continents: their migration and selection might thus relate to human activity (e.g., via human travelling and the trafficking of goods, and via selection, perhaps by chemical compounds) (Andersen et al., 2012).
What is C. elegans geographical center of origin? Are there species that are very closely related to C. elegans (see phylogeny in Box 2)?
Increased sampling in poorly sampled and isolated geographical regions might provide access to divergent populations that did not undergo the recent selective sweeps and so inform us of C. elegans’ older history and habitats.
What does C. elegans eat?
C. elegans likely feeds mostly on bacteria, but we do not know which bacteria. The sterols it requires might come from yeast or from the rotting plant substrate itself.
What is the generation time and the number of generations per year in the wild?
The latter is surely far less than in the laboratory (ca. 150), but is it by one or two orders of magnitude?
What are the relevant dauer entry and exit cues?
Whether associated organisms have an influence on dauer formation has not been investigated.
Where does C. elegans spend its winter? What are the source populations?
In temperate regions, C. elegans is most often sampled in autumn, when it is found at high density. We ignore how and where this organism survives winter, for example, whether it becomes associated with a carrier organism.

29th August 2021 CUBE Chatshaala - White Boards .
@Rechel Turkey Cube Ranchi Moina Please add your summary about your design of experiment, How to study Life span of moina.
Please give the location first before giving Longitude & Latitude @Abhijeet Singh
In yesterday’s chatshala, we started discussing with the microscopic picture which was shared by @Navneel from Kolkata. We were trying to identify that organisms which was looking very similar to Moina and daphnia.
We also discussed classification of fruit fly and moina/daphnia so that we can differentiate between them on the basis of morphological characteristics.
@Batul Pipewala Kolkata told the story of identification of moina in CUBE by @kajal.
in Ranchi we were culturing Moina since August 2019 and lost Moina in July 2021. Which was the same well studied Moina macrocopa JSK1 which was brought by Sweta and Manjuel after August, 2019 CUBE national meet from CUBE, HBCSE, MUMBAI.
Discussed about the standard protocol for moina culture , we culture Moina in container containing 250ml dechlorinated water (DC water)and feed them 1 drop of milk everyday . We feed milk drops, so that milk bacteria will grow and moinas will feed on them.
@Soumyadip from Kolkata also told that he was also having crustaceans something like daphnia /Moina when he was culturing Azola .
Then we discussed about the life cycle and life span of Moina . So in order to check the life span we tried to set up an experimental design.
according to the hypothetical experimental design to check life span of Moina, 1st we need to identify the adult gravid Moina that can give birth to baby moinas.
Then we can isolate them in a container with 250ml DC water and feed them 1drop milk everyday day.
When the mother Moina will give birth we will get day1 moina . Then mother Moina will be separated out and we can observe day 1 moina for further observation.
When these moinas will become adult and gravid and produce baby Moina we will keep separating out new baby Moinas and we will keep observing them until they die.

Hello everyone, thank you for including me in the discussion. I am Navaneel Sarangi, from St. Xavier’s College Kolkata. Project details : Experimental observations of Pondwater sample from Saltlake, Kolkata -
Objectives : Immediate Objective : To establish microscopic biodiversity of single Pondwater samples from Saltlake, Kolkata. (I have not decided whether to focus on a particular phylum)
Short term Objective : To analyse methods of enrichment of pondwater samples, as well as isolation of organisms of interest followed by culturing of the same.
Long term Objective : To establish taxonomic microbial biodiversity of pondwater samples (multiple) from Salt Lake Kolkata. Database setup with nomenclature annotation of samples visualized. Establishment of protocols for enrichment of pond water samples for microscopic analysis. Establishment of protocols for isolation of organisms of interest followed by culturing of the same.
Apart from this, I am an aspiring astrobiologist, and involved in different research activities through my position of VIsiting Scholar at Blue Marble Space Institute of Science. However, any and all aspects of science interest me, especially those we can perform without the complications of an institutional laboratory.
Micro biology and Space great combination:ok_hand:
What is the actual size of this waterflea? @Navaneel
Hello Navaneel,
Really appreciate the detailed note of your immediate, short term and long term objectives regarding the culture and maintenance of aquatic microorganisms.
I have some questions regarding the same:
What do you mean by establishing microscopic biodiversity? I mean isn’t it already established in the natural source? (Salt lake) do you mean culturing?
What do we mean by analysis methods of enrichment of samples? A more simple elaborate sentence will be better for someone like me to understand the motive.
Is Salt Lake, kolkata a source of freshwater body? Why is the name salt lake ?

Please give a summary of your Single Line Cultures as BREAKING NEWS @Aswathy Suresh CUBE @Yash Sheregare CUBE @Isha Pawle @Sidhy Kerala Drosophila and others.
How many are doing good?
A better sentence would be to analsyse the microscopic biodiversity, and classify the same according to taxonomical heirarchy. Thank you for pointing it out.
Pond samples are a real-word reflection of microbial communities. These ecosystems have unqiue interactions, which control the population of each niche present. What factors help in incresing the general population of microbes in the medium ? What factors influecne particular niches ?
Eg : If we observe a community of Paramecium in our sample, can we selectively enrichen the paramecium community ?
SaltLake is a Municipality division in Kolkata, easily demarcated from the rest of the city. It used to be a part of the East Kolkata Wetlands, which still supports a brackish ecosystem. It was filled up in the 1950s to build one of the first planned cities of India. You can find more information here : http://www.ekwma.in/ek/wp-content/uploads/2015/09/NewsletterVolume1.pdf

What is the source of water?Is it the municipal taps?
Yes. But I dont think it is unified with he central distribution system of saltlake
I have a question. The modified microbial culture media using coconut water, what were te constituents and standardisation of the same?

What do want to show us through this picture!?
Amazing capture @Seethalakshmy CUBE !
I think during Chai and Why? We lost the account of your identification studies.
Were are we in the identification of your ants!
Also @Gaurangi Dhuri has some similar interests as what your long term objective suggests! Please collaborate!
Chai and Why … presentations were amazing and impactful. How students have made home labs and doing research during pandemic…was so inspirational. Congratulations to everyone for the efforts and passion in science.
[11:04 PM, 8/30/2021] Seethalakshmy CUBE: Our plan is,
find immobilized ant from our culture( or catch an ant and kept in refrigerator ). Looking their body parts by using phone microscopy. @Anjani Kumar Kashyap CUBE
[11:08 PM, 8/30/2021] Seethalakshmy CUBE: Ok @Abhijeet Singh!
my objective is To culture the Cardamine in my homelab.
Actually this is not a good culture.
Because the cardamine shows less growth as well as some plants are died.
I want to overcome this.
[11:10 PM, 8/30/2021] Seethalakshmy CUBE: Thank you!@Abhijeet Singh
Yes! you are right! We want to restart this.
[11:13 PM, 8/30/2021] Seethalakshmy CUBE: Sure! Let’s discuss collaboratively!
Yes @Gaurangi Dhuri
Please ask questions as well as tell us your ideas!
Have you noticed any specific morphological feature? Which order it belongs to?
They are coming under order Hymenoptera @Dr. Sarita kumar Delhi CUBE ma’am
Any specific character of Hymenopteran? Have you ever observed wings in ants like present in other Hymenopterans such as bees, wasps…
hello navaneel.I appreciate the work in your home lab:tada: Keep it up!!
I am interested to know about the
Microbial diversity you are finding out.
3.Why only salt lake as a source of marine ecosystem ?
What is your expected results.
3.Also I would like to know the detailed observation you got from daphnia photo
4.What is nomenclature annotation that you mentioned
@Navaneel@Batul Pipewala Kolkata @Saida Sayyed @Arunan HBSCE and others
What do you mean by immobilized ant? What benefit does that give over any non immobilized ant?
Yess…
[8:43 AM, 8/31/2021] Seethalakshmy CUBE: Yes @Dr. Sarita kumar Delhi CUBE ma’am
Hymenoptera have 2 pairs of wings (fore wings and hind wings) the fore wing is long compared to hind wing and membranous

Expt documentation : Study of microbes in tap water from saltlake kolkata.
[9:40 AM, 8/31/2021] +9128389: Tap water is a common source of drinking water. In this expt, I have used coconut water (5ml ) with an ear bud full of tap water inoculum, kept in the blue lid urine collection cup. I will check for microbial growth 24 hours later. The vessel has been sealed with parafilm to prevent contamination. The urine cup seal was broken 10 mins prior to start of experiment.
To check for direct microbial growth, I envisioned potato surface based microbial growth. Here in the picture, we have a control potato slice with no inoculum on the right. The plate has been sealed with parafilm.
On the left we have the experiment potato plate. The inoculum has been streaked with an ear bud in a z pattern of continuous streaking.
[9:42 AM, 8/31/2021] +91 8389: In the absense of an autoclave, all the instruments were sterilised with home made 70% ethanol and flamed with a gas lighter. Heat sensitive material such as plastic was thoroughly cleaned with ethyl alcohol. To prevent airborne contamination, the exposure of experiment surface to air was minimised as much as possible.
Coconut water broth was collected 20 mins prior to the experiment.

[11:11 AM, 8/31/2021] +91 28389: ok sir
[11:11 AM, 8/31/2021] +91 28389: Yes sir we are
[11:12 AM, 8/31/2021] +91 28389: Not streaking with coconut water. I am using coconute water as a broth to culture any microbe in the tap water. If the quantity of microbes is less, then we may not get any colonies on the potato, but the coconut water may enrichen the same
[11:15 AM, 8/31/2021] +91 28389: For short term growth like 24 hours, my previous laboratory experience has been that there is no drop in optimum growth of culture for aerobic microbes. But as you mentioned, I may do a comparative study of sealing them and not sealing them to see if there are any changes.
[11:22 AM, 8/31/2021] Arunan HBSCE: Please be careful because you are possibly enriching microbes from elsewhere:face_with_monocle:, like from tap water using nutrient rich coconut water. @Navaneel
What are your EXPECTATIONS?
Please explain your DESIGN fully to be aware of possible consequences.
[11:25 AM, 8/31/2021] Arunan HBSCE: Don’t you expect any pathogenic bacteria being enriched in this process?
Let’s write down the full Design clearly and discuss the consequences. @Navaneel
Do you see a difference between that of @Aditiya Joshi CUBE and of your Design of HomeGrown Microbes? @Navaneel
Design of the experiment :
an earbud soaked in tap water is immersed into 5ml of Coconut water. The experiment is being carried out in a safe enclosed environment, adjacent to a doctor’s chamber.
Expectations : There should be no microbes present in the tap water submerged culture as it is chlorianted by the Municipality. Likewise, the surface culture on potato should not yeild any bacterial isolates.
Alternate Hypothesis : If there is presence of colonies of microbes on submerged or surface culture, there is contamination of microbes in the tap water being used for drinking resources.
Since most of us use this water in one way or the other without additional filtering, and there have been no untoward incident so far, I expect the microbes been enrichened are not pathogenic.
Opening and closing of leafs pattern observed in Chini Gulab or Sun Rose . Botanical name:- Portulaca grandiflora My mother brought this plant from nearby nursery two weeks before. I observed the leafs showing some closing and opening kind of pattern. So to look into it I took a photo yesterday in the evening and a photo this morning. I can clearly see that the plant’s leafs are opening and closing. Compare the two photos. What do you see @Lakshmy PJ CUBE @Arunima SN Nattika Cardamine @Aswathy Suresh CUBE @Arunan HBSCE @Batul Pipewala Kolkata @Aditiya Joshi CUBE . Can we also developed Chini gulab as a model for sleep wake studies in Phyllanthus??? Please post your comment and help me do this! Looking forward…!Yes sir. In case Aditya’s experiment design, the microbes being enrichened are directly derived from the fermented coconut broth. Since the coconut broth is usually consumed in some manner or the other, the organisms are not pathogenic.
In my case, I am not using the coconut broth itself as the isolate, but as a medium for enrichment.
How does Doctors’ chamber help?
The doctor’s chamber provides a sterile environment to work in and has air flow systems isolated from any living area. All air inlets are fitted with HEPA filters. I myself use a lab coat, sterile nitrile gloces and mask while processing any sample. I make sure to sterilsie all and any surface with 70% ethanol before and after the experiment.
[11:31 AM, 8/31/2021] Arunan HBSCE: Why do you doubt? @Abhijeet Singh
Time in AM & PM is essential for getting clear idea.
Please give essential details
[11:34 AM, 8/31/2021] Arunan HBSCE: Do you expect to get collaborators, if your initial requirements are this stringent? Can’t we do microbial research without such demanding requirements? @Navaneel
[11:35 AM, 8/31/2021] +9128389: yes sir, that is some additional precaution. Tap water shouldnt have any pathogenic microflora, and rhizobial cultures can also be processed without any of the above requirements. In fact i used to do the same, but due to the worry of my parents (who are doctors) I had to move to the same area
[11:35 AM, 8/31/2021] +91 28389: However, the requirement of gloves and ethanol or any sanitiser must be there
Why do you need coconut water to enrich them will not boiled potato itself provide nutrients to the microbes?
They are two seperated mediums mam. One is a submerged culture medium (Coconut water) and the other is a surface culture medium. Often, especially in the laboratory, we first perform a submerged culture to increase the concentration of microbial cells before following through with a surface culture.
Let’s move forward step by step. @Navaneel
What is your research question?
Let’s clarify and proceed.
Research Question : Are there any microbes coming with the municipality tap water
Details:-
Time of pic on left side :- 8.35 AM
Time of pic on right side:- 5.40PM
This is a boiled potato slice showing growth of bacteria from just air after 24hrs@@Navaneel@Aditiya Joshi CUBE
yes that is why i had to seal the potato in. Otherwise there would have been air borne contamination
Correction @Navaneel On this boiled potato slice I had transferred nematodes with two drops of tap water.Nematodes also have bacteria attached to their bodies and tap water bacteria are also present besides air.
[11:58 AM, 8/31/2021] Batul Pipewala Kolkata: Sorry there is a mistake ,Correction given above
[12:02 PM, 8/31/2021] Batul Pipewala Kolkata: For airborne contamination you can put a control slice exposed to air. What do you think @Aditiya Joshi CUBE @Navaneel is the importance of controls in an experiment
[12:02 PM, 8/31/2021] Arunan HBSCE: Please post your Control simultaneously. @Batul Pipewala Kolkata
What were the Controls?
Are they not crucial?@Batul Pipewala Kolkata @Navaneel
Let’s go ste by step.
[12:03 PM, 8/31/2021] Arunan HBSCE: Let’s pay more attention to Design of experiment based on what is our Hypothesis that we are testing. @Batul Pipewala Kolkata @Navaneel
Let’s state the Hypothesis.
Yes, my control is on the side of the expt potato. It has every single exposure except to tap water. Any bacterial growth on that potato would be independt of tap water
[12:03 PM, 8/31/2021] Batul Pipewala Kolkata: Yes Sir controls will give a clear pic by comparison with the test
[12:04 PM, 8/31/2021] Batul Pipewala Kolkata: Can you show in the pic label the control
Just one potato slice or in at least duplicate?
Let’s have a full DESIGN, stated clearly. @Navaneel@Batul Pipewala Kolkata @Aditiya Joshi CUBE
Atleast 3 potato slices as test replicates would be needed besides the controls @Navaneel
yes it is labelled mam. I am sendin the experiemnt design none the less
Data Collector: Chitra Achari Trying to recieve more photos from Kovilpatti.
Also clarify which test slices for submerged and surface culture?
30th August 2021 - CUBE Chatshaala Discussion - White Boards
Discussed about model systems : Fruit Fly, Mosquito, Ants (Insects).
30th August 2021 : Discussion white board Where can we find Fruit Flies?
How Fruit flies Look Like? Is it easy to distinguish from other insects?
What are the characteristics features that very well visible in fruit flies? Which part of the body well visible like… Wings, Eyes, Abdomen…? What is the actual size of this small flies? What are similarities & Dissimilarities between Fruit flies and Mosquitoes?
Fruit Flies and Mosquitoes, both of them are belonging to;
Kingdom : Animalia
Phylum : Arthropoda (Because both of them have joined appendages)
Class : Insecta (Body divided in to 3 parts Head, Thorax abdomen. Have 3 pair of legs & 1 pair of antenna, also have compound eyes.)
Order : Diptera
Both have 2 wing (one pair of wing)
Coming in to Family level Fruit Files are belonging to Drosophildae, Mosquitoes are belonging in to Culicidae.
One interesting point added by @Navaneel that insects have fore wing & hind wings. Only Fore wing is Expressed. Hind wing converted in to halteres in the case of Dipterans.
Flies are insects of the order Diptera, the name being derived from the Greek δι- di- “two”, and πτερόν pteron “wing”. Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Fly - Wikipedia
Are there examples of insects having just halters…?
It is generally accepted that the halteres evolved from…
So if it is easy enough for you to keep an ant in the refrigerator and immobilize it have you obtained any immobilized ants yet?
Wow! Even before September?
Please get what percentage of Mango trees at this lower Latitude are flowering before September? @Abhijeet Singh @Aswathy Suresh CUBE intresting mam …

Yes sir!
I trying to receive more data from this place and state! Crucial time in mapping these observations!
Quarantine Mode
Trapped three fruit flies in two bottles.
Seems to be of different types of fruit flies.
Can we standardise the angle at which we are taking the photos? Then maybe it can be analysed better. Angle as in the lateral view, or the ventral view.
Wow… Great what is your further plan @KIRAN CUBE ?
Plan is to start the single line Cultures of these fruit flies and identify them.
After getting 1st progeny of these fruit flies I will be transferring in medium.
Expecting to see eggs tomorrow (1st September 2021)

Great! @KIRAN CUBE maam the second bottle on right shows an interesting fly trapped…
Almost looks like the bottom fly has black eyes
Are they fruit flies?

I am guessing the cotton plug wasn’t tight enough and that invited a Different fly inside the Single line culture - a culture that was started with just 1 pregnat fruit fly that gives a pure culture @Gaurangi Dhuri
The brownish and some what blackish patches are the empty pupal cases
Objective - To Culture and Map and find Drosophila melanogaster in our Locality and Entire India through Collaboration by CUBists @Batul Pipewala Kolkata mam and @Aditiya Joshi CUBE I had a question. Are you using normal potato or boiled potato for the substrate?
For nematodes I am using raw potato @Aditiya Joshi CUBE is using boiled potato as a substrate for microbiological work

Caught some mosquitoes at home(Ulwe-Navi mumbai)
Objective:- Continuing Prediction and prevention of mosquito born diseases(dengue, chickungunya) Project.
History of Mosquito project:-
I started mosquito project when I was in 7th grade(2015-16) with my school friends(Adarsha Vidyalaya, Tilak Nagar, Mumbai) and collaborators from Deonar public school(Govandi, Mumbai). Including @gaurangi. We together used to catch mosquitoes at school and individually at our homes. After we catch the mosquitoes we place them on a black background and look for mosquitoes with white stripes(easily visible on black background). The mosquito with white stripes are Aedes mosquito and they are responsible for spreading diseases like Aedes and Chickungunya. So we mainly look for these mosquito. Did this for around one year or two and found out that Aedes mosquitoes are found highest in August.
So now let’s see if we get any Aedes mosquitoes from starting of September in Ulwe, Navi-Mumbai.
Today (31st Aug 2021) I got 10 mosquitoes.
No Aedes mosquitoes.
Looking forward for collaboration. Aug 2021) I got 10 mosquitoes.
No Aedes mosquitoes.
Looking forward for collaboration and comments from @Gaurangi Dhuri @Hina Mudgal Kanpur CUBE @Aswathy Suresh CUBE @KIRAN CUBE @Arunan HBSCE @Batul Pipewala Kolkata
Aedes is not a disease… it’s a type of mosquito * @Hina Mudgal Kanpur CUBE what’s the update on your mosquito studies!? Please share the updates on your work!
Yeah… I would love to collaborate with you… and restart our old project @Abhijeet Singh @Gaurangi Dhuri
[11:12 PM, 8/31/2021] Abhijeet Singh: Sorry for that! It was a mistake!
[11:12 PM, 8/31/2021] Abhijeet Singh: Looking forward…!
No problem… I shall also restart with mosquito then…
Let’s plan accordingly! What should be our immediate objective @Gaurangi Dhuri !
Also short term and long term?
Let’s built it up based on our past experience. Help me recall too!!
That time we had two hypotheses… of the most no. Of mosquitoes all over the year… and avt aedes mosquitoes when found most…

Any another features ? @Gaurangi Dhuri
Please highlight the mistake @Abhijeet Singh Let’s celebrate the Goof-ups, big and small. Let’s have Confessions of Scientists!
There are other characteristics like… the sitting position and all… but for these characteristics to be used for identification… we need to keep observing the mosquitoes when they are alive … But we can easily see the white stripes with our naked eyes when we kill the mosquito
[9:16 AM, 9/1/2021] +928389: In continuation to this
[9:19 AM, 9/1/2021] +928389: Breaking new from Navaneel’s home lab on the analysis of tap water samples.
Before breaking the seal, this is the 24 hour observation of te experimental potato substrate streaked with tap water sample. There are no apparent contamination, or growth of bacterial colony isolates on the surface of the potato sample.
This is the 24 hour observation of the control sample. It correlates that there was no contamination of the sample there are no apparent growth of bacterial colony isolates on the surface of the potato.
This is 24 hour observation of submerged culture of tap water in coconut water. Due to the natural milkiness of coconut water, it is difficult to say if there is any bacterial growth. However, I made a mistake of not keeping a control in this case which makes differentiating difficult. This needs to be noted I exp design.[9:29 AM, 9/1/2021] +91 98308 28389: Possible Avenue of reason for no growth of colonies on expt potato ;
There is no bacterial contamination in tap water
The contamination is an obligate aerobe, an since I sealed the petri dish, it couldnt grow optimally. Due to this, I have to envision some control to remove this conclusion.
The contamination in water sample is a slow grower and does not culture in 24 hours
The contamination does not find adequate growth medium in potato based substrate.
5 @Aditiya Joshi CUBE used boiled potatoes, which degrades some complex material. I used raw potato. This may have lead to difficulty in the bacterial growth.
[9:31 AM, 9/1/2021] +91
28389: Next step of experiment: to debug all of the above problems, so that only 1 is the reasonable answer. I am hopeful of collaboration in that aspect.
To debug problem 5, I will use tap water and culture it on boiled potatoes and seal it.
To debug problem 3, I am going to leave my present potato samples for 24 hours more.
To debug this step, I am going to use tap water to culture on both raw and boiled potato but without sealing off the petri dish
[9:32 AM, 9/1/2021] +91 928389: In case of number 4, I do not have an answer yet
[9:32 AM, 9/1/2021] +928389: Due to the good up in the submerged culture, I am going to redo the step once more with fresh medium and control.

Breaking news… I got 10 mosquitoes in just around 5-10 mins in the bathroom… at 10am when I was taking a bath… But yesterday night when I checked in the bathroom, I was unable to find a single mosquito…But I made a goof-up that… Many of the mosquito body parts got damaged … I think that happened as I caught the mosquitoes with wet hand and kept them when on a damp place due to which while picking them … many parts of mosquitoes break apart.
Please post some photos @Gaurangi Dhuri @Janhvi Deshmukh
Better lighting will help.@Navaneel
Yes sir, I also think that😅.
I think the problem is not lighting but focus of my camera. I’ll try to clear image next time!
What do you think @Gaurangi Dhuri @Aswathy Suresh CUBE ?
I think it’s not just focus of camera… but the background light from the top have affected the photo … due to which we are unable to see the mosquitoes clearly as in the white stripes
Yes sir I got your point!
So as we are looking for Aedes mosquito which has white stripes on its legs we need to have a clear photo to show the evidence to everyone that yes none of them is Aedes.
I think the minimum quality of an image should be that the should be clear in the sense of what are we trying to show through it!
So as we want yo show that none of the mosquito are Aedes(white striped once) the Focusing and all of the camera should done as per that!
Please correct me if I’m wrong @Arunan HBSCE and others!
Don’t you see some whitish patches?
How about giving essential information like Objective, Date, Location of HomeLab, Name of Data collector with every photo for readers to get the Context. @Navaneel
I think this image would help us to understand that how Aedes mosquito looks like! So we can clearly see the white stripes on the legs and body of the mosquito . By which we identify that yes it’s a Aedes mosquito. @Janhvi Deshmukh @Gaurangi Dhuri
Please give essential information like Objective, Date, Location of HomeLab, Name of Data collector with every photo for readers to get the Context. @Navaneel
Reference :- Wikipedia
Yeahh … this can surely help us to know… how exactly the aedes mosquitoes look like
What is your Hypothesis? @Navaneel Please state the Hypothesis.
These are some of my aedes mosquitoes … this is an old photo … In this the white stripes are visible… If u check closely
Any explanation why the potato slice is already bot looking intact? @Navaneel
What should be the ideal design to test your Hypothesis? @Navaneel
Sir the boiled potato is inherently very unstable sir . That lead to problems in generating proper slices.
I am writing the entire expt in words, so that is is easier to read and in one place. I will send it in by today.
Please describe in full, short sentences @Navaneel so that a newcomer too can follow it.
The four mosquitoes which are at the bottom we can clearly see white stripes… and even in the top one… but in this picture also… due to some light issues… all the mosquitoes are not clearly visible to check white stripes
How about posting better photos showing lighting, focus and contrast.
How to improve the photography? @Gaurangi Dhuri
Yes sir … we need to sort out with the photography … so that we can clearly check whether the white stripes are present from photos
Yes sir!!!
So actually in earlier post I did a typing mistake that:-
Aedes mosquito are responsible for spreading diseases like ’ Aedes ’ and Chickungunya.
So the the words Aedes that I have strikedthrough was a mistake and it was conveying that Aedes is a kind of Disease.
Correction:-
Aedes mosquito are responsible for spreading diseases like Dengue, Chickungunya.
[10:31 AM, 9/1/2021] Arunan HBSCE: Which parts of mosquitoes are important for achieving your Objective?
Please always start with Objective and also give Location of CUBE HomeLab, Date, Name of Data Collector with each photo @Gaurangi Dhuri
[10:32 AM, 9/1/2021] Arunan HBSCE: What is your comment on the bathroom mosquito catch by @Gaurangi Dhuri ? @Abhijeet Singh
I think … I saw many mosquitoes in the bathroom today… because in the night they maybe coming out in other rooms for food and in morning they maybe coming to their original position… maybe they are breeding in bathroom itself…
[10:35 AM, 9/1/2021] Arunan HBSCE: So what is your plan to trouble-shoot this issue of taking photos? @Abhijeet Singh
Please comment on photos of @Navaneel
Let’s improve the quality of data while posting.
Let’s have a discussion to resolve this urgently and publish a Blog on it in Stem Games.
[10:37 AM, 9/1/2021] Arunan HBSCE: What is our Long term Objective by collecting Mosquito data? @Gaurangi Dhuri @Abhijeet Singh @Hina Mudgal Kanpur CUBE Are they all fruitfly larvae?
[10:40 AM, 9/1/2021] +91 87289: Okk … so our basic objective to catch mosquitoes is to find in which month in the whole year are we getting more mosquitoes and in which month are we getting more aedes mosquitoes… so to identify aedes mosquitoes… we need to find whether the legs and stomach of mosquitoes are having white stripes… If there are white stripes present in the legs then it’s an aedes mosquito… so to identify this… we need to take care that … the legs are not damaged
[10:43 AM, 9/1/2021] +9187289: Our long term objective is to find the most amount of mosquitoes in which seasons… and most no. Of mosquitoes in which season… so accordingly we can take more precautions in particular season… and even inform others
[10:43 AM, 9/1/2021] +91 87289: Am I right @Abhijeet Singh @Hina Mudgal Kanpur CUBE … ??
What are the white spots in the pic are they not bacterial colonies @Navaneel
[10:47 AM, 9/1/2021] +9128389: Mam i think they are instrinsic to the potato
[10:47 AM, 9/1/2021] +91 8389: those are starchy exudates which I was observing. Quite distinct from bacterial mucilaginous colonies.
[10:48 AM, 9/1/2021] +9128389: But I can be wrong in identification, I will break isolate tomorrow to allow for debuggin the long term growth problems28389: for plating in general
Are u talking About this white spots @Navaneel … ??Did you see them before plating? Any pic evidence?
[10:48 AM, 9/1/2021] Batul Pipewala Kolkata: Yed
[10:49 AM, 9/1/2021] Batul Pipewala Kolkata: Yes
ah no. those are water vapour marks
[10:49 AM, 9/1/2021] +91 87289: Yaa that’s what I thought
[10:49 AM, 9/1/2021] +91 87289: Hence asked
I will click a better picture
Okk
Ok
[10:50 AM, 9/1/2021] +91 28389: This was the start of the experiment
[10:50 AM, 9/1/2021] +9128389: I should have clicked a closer picture
What was your expectations in each case @Navaneel !?
I think with the objective, expectations are also an important aspect!!
[11:37 AM, 9/1/2021] +91 28389: .
[11:37 AM, 9/1/2021] +91 28389: @Abhijeet Singh
[11:45 AM, 9/1/2021] Abhijeet Singh: I think you mean to say ‘goof up’.
So as you are going to redo the submerged culture, what will do do with the submerged culture you have currently!?
I think we should also follow up that! Let’s see what happens!!
That’s would be great @Navaneel !! Please send us updates!
Also when you redo the submerged experiment let’s think of what are you going to name it! Because the labels of the new one should not let us forget the one which you have currently let’s together follow it up! @Navaneel@Aditiya Joshi CUBE @Arunan HBSCE @Aswathy Suresh CUBE
[11:51 AM, 9/1/2021] Abhijeet Singh: I think the legs are very important for differentiating between Aedes and non-aedes mosquitoes. So while trapping lets make sure that we don’t hit that hard that it’s legs gets broken from its body!
What do you think @Gaurangi Dhuri !?
Yess… I also wrote the same thing… that legs plays an important role in indentification
The photos which she sent needs to have a better resolution!
And gaurangi and I discussed about catching mosquitoes in bathroom. So actually at my place (ulwe) mosquitoes come in evening by 5.45 pm or something like that.
At day time we can see that. When we do cleaning and all in the morning they are found behind the table or underneath the bed. As in the dark places!
And better lighting and better focus too.
Please start clicking and posting better evidences. @Navaneel
yes sir
Now I’m not able to make it in a statement but let’s try to construct it through what we understand.
So what I think our long term object should be is that we should be to able to predict the diseases that may occur in a month or months particularly as per the data we collect through mosquitoes Trapping and identification of mosquitoes trapped
I don’t know if the idea is transferred but let’s discuss!! @Gaurangi Dhuri @Arunan HBSCE @Hina Mudgal Kanpur CUBE
What do you mean by submerged experiment?!@Abhijeet Singh @Navaneel
What is the objective?
What is the research question?
Yes, what is your expectation based on your stated Hypothesis? @Navaneel
Design of the experiment :
an earbud soaked in tap water is immersed into 5ml of Coconut water. The experiment is being carried out in a safe enclosed environment, adjacent to a doctor’s chamber.
Expectations : There should be no microbes present in the tap water submerged culture as it is chlorianted by the Municipality. Likewise, the surface culture on potato should not yeild any bacterial isolates.
Alternate Hypothesis : If there is presence of colonies of microbes on submerged or surface culture, there is contamination of microbes in the tap water being used for drinking resources.
Since most of us use this water in one way or the other without additional filtering, and there have been no untoward incident so far, I expect the microbes been enrichened are not pathogenic.
How about looking around for possible breeding places too? @Gaurangi Dhuri @Abhijeet Singh @Navaneel
Can Pagalapos be sites for mosquito breeding? @Abhijeet Singh @Gaurangi Dhuri Can’t we restart Pagalapos as model for many research studies? @Saida Sayyed @KIRAN CUBE @Shivam CUBE NEMATODE
Submerged culture : The bacterial growth happens in liquid media (Coconut Water)
Surface Culture : The bacteria growth happens on the surface of a solid medium (potato)
What is meant by resolution? @Abhijeet Singh @Navaneel@Gaurangi Dhuri @Aastha Ahuja Cube @Ishita Assam
[12:07 PM, 9/1/2021] +987289: Yess… we can predict the disease caused by mosquitoes especially dengue and chickenguniya as its caused by aedes mosquitoes… in which season or which particular month… and if we get collaboraters then we can find whether the location affects the causing of disease in particular seasons or months … @Abhijeet Singh right?
[12:08 PM, 9/1/2021] +917289: Yess… It can be great work… if we connect pagalapos and mosquitoes studies…
So what @Navaneel and I mean from ‘Submerged experiment’ is that
In one of the cases navaneel is using Coconut water as a source for growing microbes(if present) in tap water.
So @Navaneel used an ear bud and dipped in tap water and kept that in a container with coconut water. So that ear bud containing tap water sample is ‘submerged’ in coconut water.
I think I’m getting it correct @Navaneel . Please correct me if I’m wrong anywhere!
If I could please know what are pagalapos ?
You mean you want to predict Mosquito borne diseases in the area through this? Please clarify.
What is the incidence of Mosquito borne diseases in your locality, as per Department of Health?
[12:09 PM, 9/1/2021] +91 28389: yes
[12:09 PM, 9/1/2021] +91 28389: absolutely
[12:11 PM, 9/1/2021] Arunan HBSCE: Fresh coconut water? Because there will be possible differences in the microbe profile of fresh coconut water vs that was kept for sometime. Don’t you think so? What is your explanation on this? @Navaneel@Abhijeet Singh @Gaurangi Dhuri @Aditiya Joshi CUBE
[12:13 PM, 9/1/2021] Arunan HBSCE: Is the last sentence dealing with your Hypothesis? Can you state the Hypothesis more clearly as in Science, so that it can be verified or falsified? @Navaneel
[12:15 PM, 9/1/2021] +91 28389: Yes sir. Using fresh coconut water. But I want to do the exp with the remnant water as well, however I have not designed the exp yet.
[12:15 PM, 9/1/2021] +91 28389: yes sir
Please describe step by step procedure, how you prepare this set up of submerged culture? @Navaneel
Objective : Study of microbial contamination in Tap Water in Saltlake, Kolkata
Hypothesis : Due to proper Chlorination of water by the Municipality, I hypothesis that there are no microbes to be cultured from the Municipal water source.
Can’t we do this study of incidence of Mosquito borne diseases, across the country? @Gaurangi Dhuri @Abhijeet Singh @NavaneelStep 1 : Clean the coconut surface. Spray 70% alcohol to clean the cocnut outer shell. Ensure hands are washed to prevent contamination
Step 2 : Use a sterilised Rock / Sickle to break the coconut. Collect water with minimum contamination with cocnut fibres in Sterile collected
Step 3: use boiled muslin cloth (for sterilisation) to seperate fibres from the coconut water.
Step 4: (Variations from this step) → Take 5ml aliqout from cocnut water source.
Step 5 : Collect 10 ml tap water in sterilised collected and soak sterilised ear bud in tap water.
Step 6 : Dip Ear bud into 5ml coconut water aliquot in sterile collected.
Step 7: (Variations) → Close cap and seal with parafilm to prevent airborn contaminations.
Step 8 : Make 5ml cocnut water control in sample collecter. Exact steps as listed above are followed except dipping ear bud into the medium. The cap is closed and parafilmed.
Variations for parafilm : Dissolvable glue. Vaseline. Wax.
Variation in steps → Parafilm should not be used if the culture is aerobic. It may generate anaerobic conditions in brothHow will u proceed with experiment?
Is there any specific reason behind dipping the bud in tap water n then putting it in coconut water @Navaneel
[12:34 PM, 9/1/2021] +91 28389: Tap water is the inoculum.
[12:34 PM, 9/1/2021] +91 8389: Coconut water itself doesnt have any microbe in it for fermentation
[12:34 PM, 9/1/2021] +91 28389: it myst be exposed to air or inoculum
Okay… But how dipping the bud will be needed. Can we simply add a drop of tap water or 1ml of tap water as such directly in coconut water
i think the bud provides an additional substratum, in case the microbes are very les sin number. it is strictly not needed, but we used to do it in our lab when there was really less concentration of a culture. And also the bud provides a mesh to capture the microbes form the tap water, instead of the entire water entering into the media and diluting it, along with chlorine ions.
[2:24 PM, 9/1/2021] +91 88988 87289: Yess we can… we have to contact with BMC offices and collect the data of different wards and stated all over the country… and then we can compare it with our studies … and check whether our observations are going right or there is something which is missing… what do u think @Abhijeet Singh @Hina Mudgal Kanpur CUBE @Arunan HBSCE ??
[2:28 PM, 9/1/2021] +91 88988 87289: Pagalapos are basically the holes that are present on the lid of the gutters… in the rainy season this holes will have water and other times it can be dry… these holes may have different organisms… there are even possibilities that pagalapos are the breeding site for mosquitoes @Navaneel …
Am I right @Abhijeet Singh @Arunan HBSCE @Hina Mudgal Kanpur CUBE … if I am wrong … pls correct me…
Please post some photos of Pagalapos sites from your locality @Gaurangi Dhuri @Abhijeet Singh
Breaking news. …pupae stop developing… I trapped flies on 8.30 pm on 29/07/2021 …after that I seen some larve on 1/08/2021 … it’s a open Bait setup in which I used tomato and cucumber as a bait…after that I seen some big larve on 4/08/2021 it’s a housefly larve …in that setup I seen two types of larve some are 3 mm in size and some are 5 mm in size I seen some pupue on 05/07/2021 some are in 3 mm size some are 5 mm in size after that I waiting for new flies some housefly emerge and one fruitfly emerged on 08/08/2021 but there so many pupae you can seen here they stopped developing I couldn’t seen from 15 days when I seen today I found to that pupae are not developing …. And why ? Location: Wardha data collector: janhvi deshmukh. Time :5.07 pm janhvi deshmukh homelab bajaj College of science wardha Maharashtra
This is fascinating
Something that maybe cubists can think of testing in their fly cross breeding of strains from different parts of the country, to see if they aren’t compatible due to sattelite DNA

[9:29 AM, 9/2/2021] +91 28389: Experiment 3 : bacterial culture of submerged culture specimen of tap water from saltlake kolkata
Continuation of images from 1/09/21.
In Exp 2, we had taken a ear bud full of tap water and inoculated coconut water medium. We had allowed incubation for 24 hours. Following the, we had streaked the sample on potatoes from expt 3 (as stated above). The potatoes are meant to act as a solid substrate for microbial growth. The potatoes were boiled, and the petri dishes were not sealed, but covered to allow aerobic respiration.
A control with no streaking was maintained as well
Pic A : Objective - to study bacterial contamination in tap water of saltlake kolkata. Date : 2/09/21 picture by : Navaneel Sarangi Location : Saltlake Kolkata.
In this picture we can observe a white mucilaginous coating growing on te surface of the potato. This picture is taken for reference before breaking sterility
contamination in tap water from saltlake, Kolkata. Date : 2/09/21 picture taken by : Navaneel Sarangi location : saltlake kolkata
In this picture we an seen clear mucilaginous covering and growth on the surface of the potato. I comparison this was the picture yesterday
We can trace vaguely the path of microbial growth along the potato. This also verifies that the bacterial growth was from the coconut water preferentially.
Pic c : This is an image of control. Objective : to study bacterial contamination of tap water in saltlake Kolkata date: 2/09/21 location : saltlake Kolkata picture by : navaneel Sarangi
We can observe no mucilginous growth. However there is certain red splotches. This I am not able to explain.

Very amused to see the potato is not sliced with a sharp knife with edges ‘eaten up’ @Navaneel Can’t we be more keen to *get a smooth slice like the smooth surface of the culture medium, in the petri dish? @Navaneel
yes sir I am trying that. With the boiled potato, it becomes highly unstable to get a perfect cut. Maybe a half boiled potato will be better stable to get a more smooth cut
Please give dates and after how many days etc., so that readers will find to follow you easily and join you as collaborators. @Navaneel
yes sir I mentioned here. I am sorry, I should have mentioned that the potatoes were streaked 24 hours earlier
Is this inoculated with coconut water?

[10:33 AM, 9/2/2021] Arunan HBSCE: Do we have any Controls? Don’t you think appropriate Controls are important for each experiment?
How will we redesign the experiment to convince all of our result? @Navaneel
What exactly is meant by ‘submerged’?
Please clarify @Navaneel
[10:38 AM, 9/2/2021] +91 98308 28389: As mentioned yesterday sir by @Abhijeet Singh and me, culture is a the growth of microbes in a favoured environment. There are various kinds of culture method, one of which is submerged culture. in this case the microbe is given a liquid medium of growth, so that the colony of microbe is submerged for growth inside the liquid.
[10:39 AM, 9/2/2021] +91 98308 28389: Sir I made 1 control, to compare between tap water exposed potato and no top water exposed potato. Ideally, we shoudl also have controls for boiled and raw potato, aerobic and anaerobic cultures as well.
[10:46 AM, 9/2/2021] Arunan HBSCE: How can we get potato slices reasonably similar to the petridish culture medium, instead of looking uneven and shattered?
How is boiled potato a simulation of petridish medium in conventional lab? This has been an important comparison while preparing alternate HomeLab medium for Fruitflies too.
So, let’s justify why slices of boiled potato can be simulation of lab medium for culturing microbes? @Navaneel@Abhijeet Singh @Aditiya Joshi CUBE and others
[10:48 AM, 9/2/2021] Arunan HBSCE: Please describe the method of preparing boiled potatoes from the beginning. @Navaneel for all to follow.
Please post short clippings of each stage of preparing the potato slice. @Navaneel
Hi @Navaneel, interesting experiment. I had a few questions about experiment design:
What is your control, can you explain?
How much sample have you added to your potatoes?
Can we do something to ensure that the growth is not from the coconut water itself?
[10:50 AM, 9/2/2021] Arunan HBSCE: Please photos of the whole sequence starting from freshly prepared potato slice till the latest observation with essential description and your conclusion, so far. @Navaneel
[10:55 AM, 9/2/2021] Arunan HBSCE: Are you having a liquid culture imitating nutrient broth culture?
Or you are using Potato to try simulating Nutrient Agar medium?
Please clarify before using complicated terms like submerged culture.
In case you have some reasons to use the term submerged culture please describe so that all can follow you and join you as collaborators. @Navaneel@Abhijeet Singh
[10:56 AM, 9/2/2021] Arunan HBSCE: Too much information in one sentence! Please clarify. @Navaneel
Yes sir, we are trying to develop a liquid culture to come as close as possible to Nutrient Broth. Potato is trying to simulate Nutrient Agar Medium sir.
For this, @Aditiya Joshi CUBE and I are trying to come up with a more standardised medium for bacterial growth using coconut water and some gelling agent like Rava.
Please finalize your solid medium simulation using boiled potato slices since you faced with several problems in your attempt.
Let’s resolve that first, since colony characteristics serves as important beginning and solid medium like boiled potato slices should help us, to start with.
What do you think needs to improved based on your initial attempt? @Navaneel
Let’s resolve this, first.
What is your comment? @Navaneel @Aditiya Joshi CUBE please add on
Standardisation in potato medium :
How are we going to sterilise the medium ? Is boiling the entire potato enough ?
How can we create a plane surface with a soft boiled potato ?
Due to the inherent yellow colour of the potato, the colonies formed are often not visible. Is there any method to solve this issue ?
We usually overturn a petridish when colonies are growing to prevent condensed water varpour from falling on the medium. Since the potato is not fixed, the plate cannot be overturned.
Please describe step by step, how did you do it last? @Navaneel
And what improvement you would like to make this time, based on what you

Process of making Potato-based Simulant of Solid Substrate (Prospective Nutrient Agar)
Step 1 : Wash Potatoes with soap and water to remove dust and contaminants. Soak in soap water to lyse most bacterial cells for 10 mins. (Not standardised : arbitary time taken - Need test for this)
Step 2 : Boild uncut potatoes (Standardisation required to extent of boiling. Essential for proper cut later on in experiment)
Step 3 : 70% ethanol wash of Potato for final sterilisation of cooled boiled potatoes
Step 4: Use sterile scalpel to careful make regular thin cuts with no potato peel in the medium.
Boiled Potato Slices replace to Nutrient Agar, at CUBE Sophia HomeLab, South Mumbai, Before transferring microbes from fermented coconut water, July 20, 2021 From CUBE Archives mcarunan
Modifications :
Need hard boiled potatoes. This will require modifications in the boiling steps.
Will need to pay closer attention to cutting the slices
Alternative :
Smash soft boiled potatoes and mash them till they are a hard bolus. Use this to fill into the petridish and make a flat surface wth a scalpel. Use dechlorinated or boiled and cooled water to adjust hardness of the potato medium.
Photos of each step with essential description, please @Navaneel
Also, i was wodnering about something. The most easily available pure cultures in the market which can be cultured comes from Yakult bottles. Since standardisation of the medium will require a stable replicating organism, and coconut water is still a natural uncontrolled process, we can use acified yakuly milk as a source of Lactobacillus casei Shirota strain.
Please restrict your description to what exactly, you had attempted the first time, with photos as evidence. @Navaneel
yes sir. I will send the photoes of the first time.

Does this colony tell us anything based on colony characteristics and the source being fermented coconut water? @Navaneel Let’s look for some reference.
Let’s collaboratively move forward, by constructing knowledge, together.
Sir I was asking how you made the potatoes. Are they boiled, and how were the kept. Were the microbes from the broth which is growing there, or microbes fro air which later inoculated into the streaked coconut water
Are you finding the results interesting?
Or, does it look terrible?
Any interpretation from your side? @Navaneel
How about close up of other bottles, while searching for Nematode looking worms? @Aswathy Suresh CUBE

Microworms present in SLBK A21 culture bottle. Date of observation 03.09.2021 : 12:45am. Further plan is to transfer this microworms from this culture to separate culture media bottle in order to identify them.
How can we transfer microworm from the media bottle @Aswathy Suresh CUBE
In yesterday’s Chatshaala we discussed the role of genes of circadian rhythm and their function discovered by scientists for which 2017Nobel prize was won.
The gene called period or per gene is controlled by negative feedback meaning when per gene switches on and forms per protein it will itself switch off the gene and prevent more per protein from being formed.During the day time per is degraded by the sunlight and hence cannot switch off its production and will continue to be made. @Aswathy Suresh CUBE @Abhijeet Singh @Lakshmy PJ CUBE @Saida Sayyed @KIRAN CUBE and others
Objective:- prediction and prevention of mosquito born diseases. Yesterday i.e. 2/09/21 I got 6 mosquitoes. None of them are Aedes. Noted the observation in log book. Here is the photo of mosquitoes. Location:- Ulwe, Navi-Mumbai. Cube locality lab Ulwe. @Gaurangi Dhuri please post your updates on mosquito studies! @Aswathy Suresh CUBE @Batul Pipewala Kolkata @Seema@Shraddha Sonavane CUBE @Hina Mudgal Kanpur CUBE please post your updates like how are you planning for starting mosquitoes project in collaboration with us! If you have started please post your updates too!
Let’s have the data from different part of the country!
Equinox is approaching!
We can use brush - wet paint brush will help for to transfer worms in a new media.
Please add your comments on the photo @Sunita Chahar CUBE Ma’am!
Did you got more mosquitoes with time!?
What the situation of mosquitoes in your locality!?
Iam planing to take this flies for further experiments.
In SLBK E16, E14 subculture bottle I found some microworms started to growing. But I couldn’t able find out in E15 bottle.
Yes, E16 - 44 days old culture. E15 - 60 days old culture. E14 - 93 days old culture. These are quite old cultures.
Which species is this? Any guess? At what time of the day did you click this pic? Can you give details plz…
In A22 bottle currently have only 1 fly, ~14 pupae , ~3 larvae. So I am waiting for to get more progeny’s from this bottle. After to make more subculture at same time for to save A line.
Can you think of any reason of not finding worms in E15 bottle…
Expectations
transferred one fly, if it is proper gravid fly expecting 50 eggs per day.
So, 23rd Day expecting ~500 eggs, ~100 Larvae, ~300 Pupae, ~70 Flies.
[11:24 AM, 9/3/2021] Abhijeet Singh: So washing with water is not enough?
Soap water, ethnol and all are necessary?
I think if we just wash the potatoes with enough water so that the dirt goes will be enough.
As far as the germs and microbes in that dirt is concerned, I think they will eventually die when you are boiling the potatoes?
What is your interpretation on this @Navaneel@Aditiya Joshi CUBE
Also what is your interpretation on ‘Homelabs’ @Navaneel ?
If I don’t have ethnol then I won’t be able to do it? Or anyone!?
[11:28 AM, 9/3/2021] Abhijeet Singh: I think we need go through some references for that.
Aedes mosquitoes lays eggs in clean water and I think in this would be clean enough for them to lay eggs. Not Sure!
National Vector Borne Disease Control Programme (NVBDCP), Telangana, Dr. S. Prabhavathi said that while Aedes Aegypti genus mosquitoes breed in clean water, Anopheles and Culex genus mosquitoes breed in dirty water. However, the official said, Anopheles Stephensi which carries malaria-causing parasite in urban localities, breeds in waters stored in containers
Because ma’am, this microworms are really small, I can only able to see when they curling in bottle side. Even if they are present in media,we can’t find out them.
E15 bottle is quite old culture and bottle wall is almost covered with empty pupal shells, dead flies etc . I checked them using proper light. But I couldn’t able to find out them in bottle wall area. May be they are present inside the media I guess.
How do we explain this?
So many pupae and no new flies?@Yash Sheregare CUBE @Aswathy Suresh CUBE @Lydia cUBe Drosphila @Saida Sayyed @KIRAN CUBE @Aastha Ahuja Cube
[11:29 AM, 9/3/2021] Dr. Sarita kumar Delhi CUBE: Yes…it’s a known fact…
[11:30 AM, 9/3/2021] Dr. Sarita kumar Delhi CUBE: E14 is older than E15… @Navaneel please post your 2nd day observations with objective!
What did you expected and what did you get!?
Please Post your inference based on your expectations and observations in short with each setup!
Looking forward…!
Very interesting @Aswathy Suresh CUBE
When were you expecting fresh flies after observing so many pupae? @Aswathy Suresh CUBE
When did you start observing this bunch of pupae in SLBK A22? @Aswathy Suresh CUBE @Yash Sheregare CUBE
Are you happy?@Aswathy Suresh CUBE
Please describe, why.
Yes sir, I got one new progeny’s in between but That was died after some days .
Currently,~14 Pupae present inside culture bottle all are newly formed pupae. So I expecting next generation flies tomorrow & day after tomorrow.
Are you happy with this culture SLBK B and why?@Aswathy Suresh CUBE
What is your immediate plan of work? @Aswathy Suresh CUBE
Amazing capture! @Aswathy Suresh CUBE did you capture this through phone microscopy or normal phone camera adjustments!?
E15 - 60 days still have flies, Larvae, Pupae. E14 - 93 days old culture have no flies, no larvae, no pupae.
E14 bottle is much easy to check microworms because that bottle quite look empty.
Interesting! @Batul Pipewala Kolkata What exactly is negative feedback in gene expression and what is its implication?
Let’s explain this separately as a topic for all Cubists to grapple. @Batul Pipewala Kolkata
Another point is
surely, there must be some references you are banking on. Please post with an introduction how to read that reference article and which part is relevant in that reference article.@Batu@Batul Pipewala Kolkata
Observed a Mimosa plant with beautiful flowers in my locality Mahad, Raigad; today morning at 7:30 a.m. Started the day with seeing its response to touch!
Expecting next generation flies on 04/09/2021 or 05/09/2021.
PREDICTION AND PREVENTION OF MOSQUITO BORNE DISEASES

[11:48 AM, 9/3/2021] Arunan HBSCE: How do we improve the photo quality to make sure the features we are looking for is clear? @Abhijeet Singh @Gaurangi Dhuri @KIRAN CUBE @Raj Yashwantrao Patil CUBE @Ishita Assam @Aastha Ahuja Cube
[11:49 AM, 9/3/2021] Arunan HBSCE: What is special about Equinox? @Abhijeet Singh And what is it?
Recently, around 01.09.2021 observed ~8 pupae in A22 bottle.
Before that I got 2 pupae 24.08.2021 & 1 new fly on 27.08.2021.
Please post appropriate videos for all to review and not miss it.
We had earlier experience that SOMETHING WE MAY MISS, BUT OTHERS POINT THIS OUT TO US @Aswathy Suresh CUBE
Yes, Now I don’t have much worry about A line culture. Because, at lest got some larvae & pupae inside A22 subculture bottle. So, I am expecting some new flies will emerges today or day after tomorrow as well.
[11:55 AM, 9/3/2021] Arunan HBSCE: When did you first notice the pupae so that you can expect when exactly, flies can emerge @Aswathy Suresh CUBE
[11:57 AM, 9/3/2021] Arunan HBSCE: Please post close up pictures of these precious SLBKA Pupae @Aswathy Suresh CUBE
Please describe how they look, according to you and when you expect them to give rise FRESH FLIES.
We must have some Expectation based on the day you started seeing LARVAE TURNING TO PUPAE😇 @Aswathy Suresh CUBE
Taken this video using normal phone camera, first focused area, then adjusted and zoomed at particular part & taken video.
So, basically you are not able to locate flies in E15, though it may have…right?
Actually ma’am , E15 culture still going culture… Mess up with lots of pupae (Hatched & Unhatched Pupae Shell) & dead flies. This case I couldn’t able to locate microworms inside culture.
[12:38 PM, 9/3/2021] Batul Pipewala Kolkata: Yes please post your observations on interesting work you are doing @Navaneel
[12:41 PM, 9/3/2021] Batul Pipewala Kolkata: Reference:https://www.nobelprize.org/prizes/medicine/2017/press-release/ @Abhijeet Singh can you take a close up photo of one mosquito each and place them to be able to see their back so markings on thorax can be seen

Breaking News
SLPbA3
Highlight - On 7th day from transferring 3 fruit flies, there are no larvae seen today.
Alert - There are some black fungi like structures Growing in this media
I am suspecting that While transferring fruit flies from SLPbA2 culture, there could be possibility of transfer of unwanted fungi that was seen near the cotton plug
Media date* - 26/08/2021
Transfer date - 27/08/2021
No of flies transferred on 27/08/2021 - 3
Observation - No Larvae or pupae seen still on 7th day
Short term Objective - 1) Culturing Single species Native fruit flies
2) Identify and culture Drosophila melanogaster species from my Locality
Immediate plan to save SLPbA3
This is what I think can be done
Transferring the 3 fruit flies to a new medium TRS-V media bottle - (I have additional one TRS-V media bottle that was made on 26/08/2021)
Observing if the fruit flies lay eggs in the new media as they haven’t yet in SLPbA3

[1:43 PM, 9/3/2021] Yash Sheregare CUBE: Yes I have followed the exact protocol followed by Other collaborators for making TRS-V Medium
The presence of Fungi can be explained as 1) in previous culture that is SLPbA2 ( - there was this black fungi seen in the culture and also near cotton plug
2) So while fruit flies were transferred, I am suspecting that the fungi was also transmitted along with fruit flies
3) Another Goof up I think is that the SLPbA2 (previous culture) had lose cotton plug so probably that can also be a reason for fungi like contaminants to enter inside the Media. @Arunan HBSCE sir @Isha Pawle @Aswathy Suresh CUBE @Man Masih Beck RANCHI CUBE @Sidhy Kerala Drosophila
Does that mean that the antagonistic property of vinegar is for a period of time and not throughout the maintenance of an culture bottle?
Since it seems @Yash Sheregare CUBE suspects that fungi were stuck to cotton plug and may have developed later when anti fungal agents lost their effects. @Aswathy Suresh CUBE @Yash Sheregare CUBE

Single line culture bottles of fruit flies. TRSV medium prepared on 15/08/2021. Transferred gravid fly on 16/08/2021.
There is fungal growth only in SLTT - J bottle. Lost that culture. Fungal growth was observed from 14 th day. In the same bottle , the number of pupae and new generation flies emerged is less. Only five new generation flies formed. One fly got stuck in the medium on the same day it emerged. Other two young flies and mother fly died on 16 th day (There had fungal growth in the medium). Two flies were remaining on 02/09/2021.Not gravid flies. Before transferring them to medium bottle , I tried to transfer them to an empty bottle to remove(complete removal not possible) the fungal particles stick to their body. Because , the flies were walking through the fungi. While transferring , one fly escaped. Remaining one was a small fly. I think it was male. Even though the new medium was ready , I didn’t transfer the fly into the medium. That fly also died. So, lost the SLTT-J culture.

I found something interesting in my courtyard. Today on 3rd of September 2021.
That place is completely filled with weeds ( green colour) maybe a weed called Japanese stiltgrass.( not sure. If wrong pls do correct me)
But I came to notice one among them was different. It had a white and green colour combination on its leaf and was so beautiful and unique from others .
Why did that particular one have a colour variation . It has got 3 branches and all the 3 coming from the root are having green and white colour combination
Why there’s a change on its colour ? .
