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. …

Sample pictures

I’m using an older model of the Foldscope microscope, and I have been testing the microscope out on a variety of samples.  The attached pictures are: [1] Blood; [2 – 3] Fruit fly; and [4] Salt. Dino

Comparing the starch powder granules and potato

They are amazed when seeing the  granules in  starch (potato). they had a doubt that what we can see in the potato also. They saw the two different granules in starch powder and also in fresh potato.

crystals of potassium dichromate

iam very  curiosity to do this slide because when iam working with chemicals i thought why cant we see the structure of chemicals .then with the help of foldsope i observed the structure of potassium dicromate.  

Water Lilly plant stem ts

I will collect the water lilly plant than i was selected one healthy stem than cut the stem thin section cuttings .After that kept in to safranine solution for stain purposes at 5 mints after stain taken slide stripes place it than observe the under fold scope . I saw holes and small holes sponge…

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

Coffee

When I spilled coffee over the water sample.

BIO 60 saliva sample

Small sample of saliva from yours truly 6 hours after eating anything. Looks to me that is some bacteria there or some microbial life.

BIO 60 post 1 Plant water layer

I’ve been growing a plant with it’s water supply in a cup sitting by the plant holder. I replace the water about once a week, and at the seven day mark a clearly more viscous grime layer surfaces. I sampled the water from the top layer and examined it under the foldscope. There were a surprising…

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…

Comparing outdoors vs table lamp based illumination 

Here I compare outdoors afternoon light as illumination with a regular table lamp illumination; to give foldscope users a perspective on how to select light. Also; I tried an informal narration mode in the video itself. I will do more of these live narration videos to both improve my craft of telling a story on…

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…

Gliding Cyanobacteria – duck pond 

Continuing on samples from the duck pond; here is a video of a gliding Cyanobacteria (possibly oscillatoria). Many fascinating things to see here; speciallyvthe slpw gliding motility which has often been a puzzle in science to uncover. What’s more fascinating is that this gliding trajectory is chiral – and the long filamentous cells are also…

Unknown giant ciliate with colored “vacuole” bodies 

In the same location as last week (Duck pond swamps); Scott, Guillermina and TA’s from Bio60 uncovered a treasure trove of microcorganisms. Here I will list what I have images so far; in a serial fashion.  First up is this beautiful giant ciliate. Over several hours of imaging; it had slowed down its swimming speed…

First attempt at photographing with Foldscope

So here’s my first attempt at photographing pollen from a Snapdragon. What I saw viewing directly through the Foldscope was different from what I could get through the camera lens. It was pretty tricky to get it in focus and I was balancing a lightsource as well since we don’t have the light module attachment…

Traveling kinks – imaging bacteria under a foldscope 

A million surprises are hidden right under our nose (or foot); all we often need to do is just look. And follow our nose (I mean intuition) and answers fall out of the sky. This is an optimists view of science. Let’s make good and careful observations..  At the same swamp (Duck pond swamp, Palo…

Di cot stem section cutining

                                           I am taken vadeliya plant stem(Asteraceae family plant) than cut the thin section cuttings put in to safranine for stain purpose few mints than taken placed to on slide observed the foldscope it’s very…

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…
