Marine Conservation & Education

Hi Everyone, I just received my Foldscopes in the Philippines. I will be working with educators and other non-profits to bring Foldscopes to kids here. My focus is on fishing communities so I am grateful for all of the ideas I find in the Microcosmos for marine-related subjects and low/no-cost projects. I look forward to…

Exploring the sea at the dining table Episode 2

Hi Foldscopers, My marine biodiversity exploration at home continues! This is fish scale of Sebastiscus marmoratus, commonly called Marbled rockfish.         In Japanese, it’s called Kasago かさご, but I learned that in the local dialect it’s also called Arakabu あらかぶ. So many names!   This is what the fish looked like on…

What is this critter in the neighborhood urban creek?

Hello Foldscopers! It is cold outside where I am, but if it is a nice sunny day, I like to go for a walk and explore the creeks in my neighborhood. I love creeks. There is something about following the movement of water that calms me down. But if you live in an urban area…

Recrystallization And A Question

Hello Everyone, This time I’ve tried making a time lapse of NaCl getting recrystallized. I have used dark field here to make the crystals look more prominent. Here are the steps I followed: 1. Prepare a saturated solution of NaCl I.e adding NaCl to water till it stops dissolving. 2. Put a drop of this…

Interesting creature in the neighborhood stream

Sampled moss from a neighborhood stream in Dublin, CA, and found this interesting fellow. No idea what it could be but it looks like it holds to something with its back while it opens its mouth wide and eats (at least that is my interpretation of what is going on). Any idea on what creature…

Some pond creatures, large and small

I collected some water from an artificial pond in the campus. Despite finding itself in the middle of an urban area, in springtime you can hear frogs calling all around. Now it’s winter and the pond is silent, full of rotting leaves fallen from the trees surrounding it. I went there looking for a pond…

Oak wood

This sample is a cross section through wood from a type of oak (Quercus pubescens). The video first shows  “late wood”, which is formed towards the end of the tree’s yearly growth phase, then you can see the growth ring boundary, which is followed by an area with large holes. These large holes are pores…

Tutorial: Surface imaging using Foldscope – ice formation

I want to start the year with new year spirit. Ice crystals. It’s -26C here; yes – you read it right. Most people are enjoying the fact that it’s colder in Montreal than Antarctica. Something we should be worried about; but that’s for another day. Basic foldscope can be used for surface imaging on translucent…

Plant puzzle

Can you find out which cells come from which plant? Which plant is not like the others and why?

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…

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.

Foldcope picnic at Spreckels Lake, San Francisco

I had a belated birthday afternoon picnic with my dear friends Dina and Summer at Golden Gate Park in San Francisco. It was such a lovely day outside, so we decided to go for a nice stroll around Spreckels Lake, which…  …offers the beauty of Monterey Cypress trees, which create a beautiful silhouette against the…

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…

Line drawn using a ball point pen

Ball of a ball point pen sometimes leaves some gap in the centre because of which single line appears as two lines under the Foldscope. The gap is so small that it is not visible when we write on paper.
