Preparing slides for demonstrations

For fundraising and showing off Foldscopes I find it a great idea to have pre-prepared slides ready to go on the run! Here are a few examples I have put together. If you are looking to fundraise, there is no better way, than to put a foldscope in the HANDS of donors with ready to…

Accidental things

I wished to observe a transverse section of the ovary of Hibiscus flower. Took a section with a shaving blade and observed it using the magnifier provided in the kit. I was being told repeatedly by my botany teachers at college that it is impossible to get longitudinal section of ovule of any flower. One…

FROM THE FIELD: Boil that water!

* I was in the field today in Panama collecting butterfly photos for a project we are working on. Its dry season so not much water available in field. This reminded me of some tropical forest survival/safety training we have our staff complete. DONT DRINK THE WATER. This is why! Thanks to my pocket deluxe…

Seagrass & Algae

The waves washed up a lot of seagrass and algae on Bulabog Beach, Boracay, Philippines on a recent stormy day. I collected a few samples to prepare for marine biology classes with Foldscopes. I first examined the specimens for hitchhikers like this juvenile sea urchin and returned them to the sea. There were two seagrasses…

Snail babies (and friends!)

Awhile back I decided to adopt a couple pond snails because my water lily pot had been getting a little messy. They took to the pot immediately, munching away at any dead leaves and cleaning the glass. It seems they may have adapted to the pot a little too well as when I returned to…

permanent marker film

Here are some images of dried permanent marker film written on the mesh pouch provided with the foldscope. It appears that a convenient approximation of the field of view of the foldscope is one square of the mesh!

Trichomes on Flower

This is an image of the lowermost part of a flower where the petals converge. I attached my foldscope to my phone then stuck the end of the flower into the hole for the lens until the object came into focus. I oriented the foldscope towards a source of light since the LED that comes…

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 a Slime Mold-1: Detection, isolation and culturing

Slime molds have fascinated me from childhood. I read about them in a library book and as an undergrad tried to culture them with little success (all I got were tracks of gnats).  The disappointment lasted many decades. A couple of years ago I got a sample of a slime mold from a friends’ porch,…

Lepidoptera wing scale damage from human-handling

An experiment: We used a roadkill specimen found during our field research here in Panama to show the level of damage a light finger touch to a butterfly wing can cause thus affecting survivability by reduced flight capabilities. We lightly touched this small section of upperwing with a finger and here you can see the…

Can we identify e-coli in water?

I am trying to identify presence/absence of e-coli in a nearby pond. Is this possible to do with foldscope? I have the basic 140x-magnification version. Over here is a video of the aquatic sample I took. although there’s a bunch of stuff “moving” around, all the movement is caused by my efforts to focus the…

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…

Friends of Kayany – Foldscope in Syrian refugee camps

Young women at Kayany Foundation's United Nations Women for Peace School in Bar Elias, Lebanon were excited to receive their new Foldscopes last week. We are thrilled and honored to work with “Friends of Kayany” to bring tools of curiosity for educating Syria's most vulnerable kids. If you would like, you can donate directly to…

Carbon dioxide sinks

  Yesterday,  whilst I was strolling in my city , I found some spiderwort species growing vigorously nearby and instantly This is what I saw:  epidermal cells and beautiful stomata amongst them. To my surprise, some (four?) subsidiary cells sorround the two guard cells that  make an stomata, a fact I did not know before…

Exploring the sea…at the dining table

Hi there Foldscopers, Hello from Japan! Manu asked me to explore planktons while I’m in Japan visiting family, and I even made my own plankton net a few weekends ago (more on this another day). But I’m finding that the ocean is not as accessible as I had imagined. Why? It’s because the coastline is…

Foldscoping on a sailboat – adventures in Yvinec

Thrilled to have a chance to #Foldscope with adventurer Guirec Soudée on Yvinec (boat). Momo (chicken) was not on the boat that day; since some repairs were planned – but we all got to share our love for science and the ocean. In the new year, let’s promise to protect this incredible ecosystem we call…

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…

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…

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…

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…

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…
