Hair Follicle

I tried to make a simple slide using the plastic reusable punched out slide and a sticky tape from the roll. I plucked my own hair out (ouch!) and placed the hair bulb (root attached and in the middle of the slide), using a piece of the sticky tape to secure the hair. The picture…

My first observation a flea

For my first observation with my new Foldscope I wanted to go back to a Robert Hooke classic, the flea. Last summer my cat got fleas, so I collected some and preserved them in alcohol. I made this perminant slide. This image is full frame, no cropping, taken with an iPhone 6 and the Foldscope…

Spicy Red Pepp (Bio60_2018)

When thinking about microscopy and the world, many often associate microscopy with science and studying living organisms. Bacteria, fungi, viruses, plants; these are all subjects that many would associate with the use of microscopes. This post is on a rather spicy topic (pun-intended) and focuses on the structure of the well-known and beloved crushed red…

Cooked Hoki Fish (Bio60_2018)

In this photo is a prepared wet slide with cooked Hoki Fish from the dining hall here at Stanford. What was fascinating while looking into the Foldscope was that you could see what seemed to be the water coursing through the organism. I could be mistaken but there was movement happening within the fish in…

Banana Peel Scraping (Bio60_2018)

It’s a food that many of us eat every morning, yet most of us probably have not thought about what lies within that characteristic yellow peel at a microscopic level. I collected this specimen by scraping off the inside of a banana peel that was sitting in the top of the trash can in my…

Hair Strand– Bio60_2018

I am about to go get my haircut as it is getting overly long, but when messing around with my Foldscope I decided to pluck a strand and see if I could observe any overt damage. This strand was pulled February 12th, 2018 and was placed on a paper slide with the clear stickers then examined…

Rosemary Flower Petal: Bio60_2018

This is a rosemary flower petal found in the garden just outside my dorm. I picked a flower, removed a petal, and framed it in a foldscope paper slide.

Exploring a Slime Mold-2: Tracks outside and within

Continuing from my previous post, you can imagine that all my free time is spent trying to do as much with the slime mold. By now I am quite certain that this is some kind of Fulgio species (perhaps Fulgio septica). However,one needs to really look for several traits before deciding the species, and so…

The Face of a Spider

Curious about insects under the microscope, I captured a small house spider (light brown in coloration) and placed it on a glass slide with a drop of water. To prevent crushing it, I placed three layers of double sided tape around the specimen before laying down the glass cover. Under the slide, I eventually followed…

Penicillium camemberti: The Rind of Brie

As a cheese lover, I’ve always wondered what comprises the white rind of brie. I used my tweezers to gently remove a spot of the airy white substance and placed it on a simple glass slide (no water). Under inspection, one can see the thin filaments of Penicillium camemberti, a fungus cheesemakers mix with camembert, brie,…

Comparison of Human Hair

My roommate and I have pretty different types of hair: mine is long and straight while hers is short and curly. I was interested in seeing what they looked like up close and if we would be able to see any huge differences using the foldscope. I mounted my hair on one end of the…

Particles in Yogi Lemon Ginger tea water

My sample was taken from the leftover water and dregs from a cup of Yogi Lemon Ginger tea that I had been drinking. To collect the sample, I poured some of the water on the slide and placed a cover slip over it. When looking into the foldscope, I was interested to see the variety…

Creature Eating Dead Spider

I was looking at a dead daddy long legs spider found in a cobweb, and discovered this creature eating it.

Polarized light foldscopy

I finally got myself a polarizing film. By this I can now polarize the light falling on the sample by placing the film between the light source and the sample and further by placing another film between the lens and the eye/camera I can block the same polarized light so that only light whose polarization…

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…

Very active organism from pond water!

It was tough keeping track of this one, but super exciting! This is pond water; lots of cool stuff lives in there. The smell was worth it! Any ideas on what this (or what it runs into at 0:04) is?

What could this be?

I viewed an ant under my Foldscope, and this is what I saw in the abdomen. Does anyone know what this is?

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,…

Mommy’s Milk (human breastmilk)

Hello again, I finally buckled down to take a look at something I’ve wanted to do for a while now.   Can you guess what this is?  Human breastmilk! I used the two-well slide and spread it out to a very thin film of liquid.  All the while my 19 month old toddler was literally…

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…
