Slices of plants

After our first ‘Atoms to Amoeba’ workshop four of our neighbouring TSWREIS (social welfare residential) schools took back two foldscopes each. Too few, yet so far several hundred students, most from remote rural parts of Telangana, have got their own “wow” moments on these foldscopes. It happened because our teacher participants went beyond conducting foldscope…

First Experiments with Foldscope

Today was my first attempt at using the foldscope to visualize scale structures, and overall I would consider it a success! Because most of my recent experiments have been focusing on Vanessa cardui, the painted lady butterfly, that was the species I began with. Putting together the foldscope I found the design quite clever and…

Help me identify these protozoa!

Hello Everyone, I have found these 2 ciliates in the seawater sample from Prabhadevi beach.Please help me identify these 🙂 I have also tried fitting the high mag lens of the old foldscope to the new one and here are a few videos I captured! It was pretty tough focusing with the high mag lens…

Measuring the Foldscope Universe-1: Using the kit scale

In any scientific endeavor, measurements are a central aspect, and so I was delighted when I saw slide scales in the new foldscope kit. This meant that I could calibrate my phone camera with the slide scales. The smallest division on SLIDE A2 is 0.5 mm. Under the foldcsope at no digital zoom, that is…

When a copepod smiles back at you..

A few friends and I have been going back and forth to San Francisco Bay; in the hope of starting larger scale sampling of the bay right here. After a few disappointing starts where we seemed to just get sand and silt (churned by the large ships bringing things into the port); we are now…

Unboxing at midnight

Dark was the night and the date slipped over to the next. The wind howled as the critters froze under the million eyes of the crisp “Thanksgiving sky”.  But we were undeterred and bravely sneaked to the box, while the others slept in fear of the dark. Assembling the foldscope was a breeze, in spite…

Onion cells

One of the first things I attempted to view was a piece of onion skin. The fold in the skin here actually gives some depth to the image. Natural light through a window seemed to work best as well, especially if not directly facing the window. I will have to try cheek cells next. Will…

Dust or Bugs?

We noticed some white particles on our Saintpaulias, or African violets, and wondered what it could be — a perfect job for the Foldscope! Unfortunately…at least from the perspective of the plant we have grown from just a single leaf…it seems that there are tiny organisms colonizing the leaves of the violet. It looks like…

Developing snail embryos

Got some snail eggs from my shrimp aquarium under my foldscope. They’re likely white ramshorn snail eggs, but I also have malaysian trumpet snails so that is a possible ID. Just received my foldscope from kickstarter today, really loving it so far.

Pooping larva (video)

Does anyone know what this is?  A fruit fly larva? Defecatory defense mechanism?

Inculcating Research Culture Right From Schools

As a part of TIFR, Hyderabad’s efforts to facilitate better science education in the local schools, it now interacts closely with four of the Telangana Social Welfare Residential Schools, all within 10 km from the institute. On regular close interactions with the teachers and students alike from the schools, we realized that schools are fast…

Foldscopes at the Cape Town Science Centre (South Africa)

Last week I had an amazing opportunity to introduce learners from a  local school to Foldcsopes as part of a mini science forum organised by the Department of Science and Technology at the Cape Town Science Centre. I was one of the academics at the University of Cape Town’s exhibition table. Everyone, from the school…

Mystery of the moth scales!

Happy Diwali Everyone, Moths are pretty rare here in Mumbai. This little guy flew in my window a few days a ago and landed directly on my arm. I have wanted to observe butterfly or moth scales since a very long time and I didn’t want this guy to flee before I could observe it’s…

Tiny bug with a giant ovipositor

I am in Delhi for Diwali, and walking around just trying to observe this city I used to call home many years ago. If you have not been here lately; this is what outside my house looked like on an average day. And in this hustle and bustle (and honking); we forget to notice the…

Planaria, Greenbush, Kansas

img_3184 This wild-caught planaria (37° 30′ 36″ N; 94° 59′ 36″ W), likely of the genus Dugesia, was found living on the underside of water foliage. Notice the marked eye-like photoreceptors used by these animals to sense a broad range of light wavelengths.

A leaf i picked up on the way

Terrestrial Algae?

     I am not quite sure what this is. It seems as if it is related to Spirogyra, or maybe something else. The specimen was found growing luxuriantly on dried up soil as a bunch of filaments…  The image obtained is of a single filament, and light source obliquely illuminating it.

Micro Fairy at UCMerced ponds

I had fantastic day working with students , undergrads, local high school students – teaching and testing foldscope. We had around 60 participants with lots of high school students from local areas. I am personally inspired to meet the students; and really excited to see what they share and post with the community. Happy to…

Foldscope Activities 9/22/17

In a very informative & exciting presentation, I learned to assemble and efficiently use a Foldscope with the help and expertise of Dr. Prakash. I can’t wait to share this with my fellow classmates! 

The view of stomata of a lower epidermis plant

We desperately searched some plant and viewed them to find a stomata at our practical class with our class teacher but could find any at the beginning.But then at last after hours of searching we finally  found this and we were all very amazed, and find it incredible to see such thing.This is all possible…

ciliates, polychaetes and my experience with the workshops :)

    hello everyone, During the workshop at IIT Mumbai I’d collected a sample of riccia from the walls and I found a variety of protozoans and nematodes in it along with polychaetes and flatworms as well! Everytime I foldscope a natural sample I’m just amazed by the fact that there really is a whole…

The way I wish I had been taught.

Dear Foldscope community: In many occasions, since I have been using my foldscope microscope, I have had the opportunity to watch fresh water oligochaeta worms. They are very abundant in debris enriched waters and quite “huge” to be easily observed in detail.  When I was a University student, I don´t remember seeing them “in vivo”,-of…

Mosquito Larvae?

A fellow teacher called me to her room today to ask for assistance. She wanted me to identify something swimming in her fish tank. She set up a small (1-2 gallon) fish tank in her room and prepared it for fish, but before she could add fish something appeared. They look like mosquito larvae to…

Mosquito

I was enjoying the weather outside today, and so were skinny mosquitoes that kept trying to feast on my blood. I managed to stop one and place it on a slide. Update- Based on a helpful comment, I went back to the slide and took more pictures. The mosquito isn’t fresh anymore, but perhaps the…

A diversity of protozoa…

Hello foldscopers!!! It’s so good to be back & this time with a really different approach & the new foldscope model! The IIT B workshop was so wonderful that the eagerness to view & post something new had increased in me. So here’s a small sample that I had scraped from the walls of a boundary…

Moss

Hello, I took a piece of Moss and observed t under my foldscope. This is my first foldscope upload and am looking forward for more and better results
