Tarragon Spice (Bio60_2018)

Adding to my collection of spices, I decided to write a post about Tarragon which is a rather unnoticed, unknown, but distinct spice. My last post focused on using a dry mount for a dried product, however,  tarragon was flat enough to be used with a wet mount to produce rather satisfying results.   Since…

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?

#Bio 60 Ibuprofen Dissolving

Ibuprofen was crumbled onto a glass slide. Water was then added by a dropper, which began to dissolve the medication.

Bayland Sludge Nematode #BIO60

These videos are of organisms found in sludge water taken from the Baylands near Stanford. The water was teeming with life, including this roundworm. At first, we identified it as a polychaete, a type of annelid worm. However, upon further inspection, we have concluded that it is most likely a nematode. Annelids tend to have larger bodies…

Live Ant exploration in class #bio60

Today in class, I was able to view a twitching ant using the foldscope. With the foldscope, I could clearly see the ant’s eyes and watch its legs and muscles twitch. It was a bit difficult getting the ant onto the slide, so I had to crush it a bit in order to secure it…

#BIO60 Post 1: Hand Callus

#BIO60: Anonymous Person’s Callus from their Palm A person that wanted to be kept anonymous was playing with a callus on their palm while in my dorm room. The callus was eventually torn off, and they volunteered to put it on a slide for me. The callus was not recently washed and therefore still had…

Flower Petal #BIO60

These photographs came from a flower petal taken from a fresh flower. The petal had a gradient of colors, which was clear under the foldscope. The more “zoomed out” photos show the individual cells on the petal, which also carry the color pigment evident in the multicolored flower. I had trouble focusing my phone camera…

Cucumber #BIO60

I took a cucumber slice from the dining hall and observed a side peel (with the outer green layer on side) under the foldscope. A network of cells can be seen but they are not very clear under the low-magnification lens. As cucumber is 90% water, many water droplets could be observed too.

Petal of Lavandula stoechas #BIO60

I plucked a flower of Lavandula stoechas from the back patio of my dorm. I observed its petal under the foldscope and I saw layers of spiky structures forming an interconnected web. Even though the cells appear tightly packed at first, higher magnification revealed a considerable empty space in the three-dimensional arrangement.  The strange mesh-like cells are…

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…

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…

Water mite (?) and ciliate in freshwater aquarium

I have a 55 gallon aquarium that houses  one giant ‘red terror’ cichlid, 3 silver dollar fish and a catfish. I stirred up the gravel at the bottom of the tank and collected some of the muck that had settled down there.  Then I imaged a drop in my foldscope. I used a glass slide and…
