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

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.

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…

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…

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…

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…

Exploring seawater a drop at a time.

Recently our class did some casual plankton surveying at the Monterey Coast Guard Jetty. We filled several jars from a plankton tow using a 202 micron net, to focus on living zooplankton, which we observed under dissecting scopes back in the lab. As predicted, evidence of spring was in the water as well as the…

Diatoms? at bay lands marsh

This was taken from one of the muddy pools of brackish water at the baylands today. Is the thing in the center a diatom?  Thanks!   #Bio60      

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…

Spiruline

Some students from Morondava public high school visited the spiruline farm of Menabe. We observed and learned more about the spiral freshwater algae called spiruline. 

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…

Surprise/quiz mystery object 

Dear Foldscope community,  Once a while out in the wild; we see something that really blows our mind. It’s even better when it’s at a microscopic scale.  Here is a question for all of you – try to guess what this is. Just for length scale – this is an object that’s 100um or so. …

Insect wing

Insect wing found in pollen samples taken from a nectarivorous bat of the genus Glossophaga Marisol Martínez

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...

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…
