A Spider Heart and a Fish Egg(?)

I am up in Grass Valley, CA visiting an aunt and uncle that live on 7 acres here. On their property is a beautiful fish pond, and the day I arrived I was told that the fish were spawning. I sampled the water from the shallows where they are spawning, and believe I found an egg…

Onion Cells

I was fortunate enough to be accepted as an initial Beta tester for the Foldscope project.  I have two daughters who love science and I had been contemplating buying them a microscope when I first heard about the project.  I can’t describe how how excited I was to receive our Foldscope package in the mail. …

Hi Manu, these are my first tests with foldscope. I teach art and photography and plan to use foldscope with my students in Finland. Ana Carolina gave me a foldscope when I visited Brasil last year. Congratulations for your work, very inspiring!! Andréa

Hacking A Lower Powered Foldscope

Recently, I decided to undertake a search for micrometeorites (you can read more about them here). Since a good portion of micrometeorites are ferrous, you can use a magnet to search for them. However, not all samples of ferrous particles are potential micrometeorites, so you  will have to examine them. I already have a handheld…

Swimming in the Forgotten Mushroom Goo

Here is my first Foldscope video I filmed on April 12th, 2017! I am getting used to focusing, holding the Foldscope/phone, and optimizing lighting, all at the same time! (Using “Frontiers”  Foldscope, indoor natural light, iPhone 4S) I certainly wasn’t expecting those organisms swimming in this goo. (4/19/2017 update: They are nematodes. Thank you, Laks…

Canterbury bells

The Canterbury Bells also known as bellflowers are absolutely beautiful. They come in shades of blues, purples, white, and pink. I first took a look at the sepal of the flower and noticed something very interesting. The sepal looked like it had hair on it. Just as Flies have protecting hair on its legs it…

Tetrahymena Ciliates

Hello everyone, A few days ago,in college, we were taught how to prepare a hay infusion broth.Our teachers have used pond water sample as an inoculum here.We were told to observe the organisms under our compound microscopes and obviously that was for a limited time which didn’t suffice my curiosity. I wanted to play around…

Roly Poly Leg

We all know this bug, whether as a roly poly, pill bug, wood louse, or Armadillidium vulgare. It’s a terrestrial member of the crustacean family that feeds on decaying plant matter, but it’s most famous for rolling up into a tight ball. Pill bugs have seven pairs of legs, each apparently covered with tiny, fine hairs! I…

Ode to Spring

Note: Post and videos best viewed while listening to Spring by Antonio Vivaldi (https://www.youtube.com/watch?v=mFWQgxXM_b8). Spring has sprung and brought with it a bouquet of color. I plucked an innocuous white blossom and pink peach blossom from two trees, then viewed the petals under the Foldscope. I discovered that Spring’s most vivid and lush landscapes may in fact lie in the…

Foldscope Use Tips & Tricks

Hello Explorers! I had the privilege of meeting Manu Prakash today, who graciously helped me use my Foldscope. He shared with me some tips and tricks which I hope all of you will find useful as well! I will update this post as I learn more. Thank you to Manu for sharing this information with…

Copepod from a Plankton Drag

I found a marine copepod with my foldscope!  This little guy was collected from seawater from Monterey, California. On March 2nd, 2017, my Marine Ecological Systems class out of California State University, Monterey Bay,  took a field trip to perform a plankton tow. We arrived at the Monterey Breakwater at 3:30pm, a sunny and warm…

Freshwater algae?

I recently examined a water sample from the reservoir at Pinnacles National Park in California. I saw some cool  cells–I think they are filamentous algae? I am intrigued by the alternation of clear and green (chlorophyll containing) regions. This post is part of Stanford BIO60  

Worm captured in foldscope

I went for a walk in Big Canyon park in San Carlos, CA with my dog  after several days of rain. I picked up a piece of rotting wood and brought it home to check out w/ the foldscope. There was a layer of mud adhering to the bottom of the wood, and I saw…

Insect wing

Help me identify these ciliates and flagellates

Without much ado, here are 5 unicellular eukaryotes that were growing in my lichen suspensions. These emerged after almost 4 weeks. I took these videos at the beginning of the year,  and only now found time to collate them. Could you help me identify these? BTW, even after 4 months, I have nematodes and rotifers thriving…

A quick post to share some observations

Dear foldscope community: This is going to be a short post  due to such a busy time I am having. Just wanted to share with you a bit of the  hidden beauty  foldscope is allowing many of us to unveal. Isn't this a gorgeous adventure! A few days ago I was trying to image epidermal...

Nothing is sharp even if paper cuts your hand

Recently i got a paper cut in my finger while i was writing my assignment. I asked myself how is this even possible DROP ASSIGNMENT TAKES THE PAPER OPENS BOX TAKE THE FOLDSCOPE MINDBLOWN. Though it was cut highly presise by machines in the industry , its not.  I was even able to see the…

Lingzhi Mushroom and Leaf

  The first black and white images, which seem more like images of the moon, are actually low-power images of the surface of a Lingzhi mushroom bud. I look forward to capturing them in higher power next time and for following the Lingzhi mushroom throughout its maturation process. The second set of green images are…

A Lousy day and permanent slides

A few months ago, a young micronaut, Aditi, had a lice infestation on her hair and before subjecting her to the lice treatment we got a couple of the critters and foldscoped them.  Without much ado here are the  collated videos. One of the things I have been wanting to do is to make some permanent…

Further adventures at lake Lagunita

With rains pouring upon us (which is a good thing for California); we decided to meet at Lake Lagunita for a quick Foldscope session. I had never seen lake Laguinta filled before (remember my past post about finding spider eggs in lake Laguinta here: https://microcosmos.foldscope.com/?p=7652)  Today morning was a different story. We gathered at the…

Copepods at Lake Lagunita on a Rainy Day

Today Manu Prakash showed us where to look for interesting microbial action.  He also shared  some tips on using the foldscope.  This sample was collected from Lake Lagunita and the movie was taken by Manu. Enjoy! #Bio60  

Observing Pollen of different flowers

We at our Pratham Science Exploratory observed pollen of different flowers also found that the number of pollen vary in different flowers. Some flowers have a lot and others have a few.

Exploring Stomata- Pratham Science Program

There are variety of leaves around us. I tried exploring Stomata in leaves of different plants, one each day. This was a wonderful experience knowing and observing plants around our center.        

Queen Ant wings

  A few days back ,I saw ants near the door and an insect with wings that  i belive  the Queen ant (motionless). Then I saw that the wings were different there were colourless patches in some area . First time in my life I wilfully plucked a wing ,gave me chills though it was…
