Microscopy in Kenya.

On 4th February we visited schools we collaborate with to implement science, technology, engineering, arts, and maths (STEAM) programs. One such school is St John Fisher’s Mbui Njeru Secondary School in Embu County. This school has been using Foldscope microscopes to unlock unseen worlds. According to their Biology teacher Ephantus Mutiga Schrodinger, this kind of…

Grape Skin and Cacao Beans

Plasmodium Falciparum Ringstages – How can I see them more clearly?

I stumbled upon Foldscopes and was interested whether they are really able to detect Malaria. Therefore i bought some Foldscopes as well as malaria parasite samples. However I am not sure if the magnification is enough to clearly detect Malaria and even distinguish different strains. The best thing i could do was zooming in on…

Invasive Beauty

I am an undergraduate student at Princeton University, studying ecology. Princeton is a beautiful place, complemented by the range of native and exotic plants planted around the campus. In the fall, these trees and bushes burst into bright reds, oranges, and yellows. With my foldscope, I examined a leaf of a Winged Burning Bush (Euonymus…

A fuzzy, white blanket

There is nothing that compares to a bite of fresh, vibrant fruit on a gentle spring day. Yet even during the chilly months, my sweet tooth never stops. So you could imagine my excitement when my roommate gifted me with an armful of blueberries, raspberries, blackberries, and strawberries.  I stashed them in my fridge only…

Autumn Autopsy

Living in the Mid-Atlantic means living through 4 distinct seasons, every single year. 4 different lives, 4 different climates, and 4 different times, complete with their own characteristics and narratives that shape every year as they pass. I’ve been thinking a lot about the anthropocene, and what life looks like because of human intervention; what…

Leaf Life

I conducted this project as part of Professor Pringle’s EEB321 class at Princeton University. I had never used a fold scope before, and was excited to see clear, interesting images through the lenses. One of my best images was the one shown here, which shows a small leaf that I found on the Princeton University…

A tiny, ancient tree

While walking to lab last week, a stunning sight caught my eye. It was a young gingko tree, covered in bright green-yellow leaves. This tree was interesting to me because I knew that all other tree of this species have dropped their leaves by this point in the season. Their fan-shaped leaves had fluttered silently…

Spotted lanternfly wing

As spotted lanternflies began to ravage the Princeton campus, students were encouraged to stomp them out if found. The student body has responded to this call: a brief stroll through the paved campus walkways reveals the carnage inflicted upon the adult lanterfly population. But few students have taken the time or had the curiosity to…

Effie’s Amazing Discoveries

These are the samples that I found at my house. The first one is grape skin, which is purple in colour. Next, in the middle is fiber from a T-shirt. Lastly, at the right is a type of vegetable.

My Dictyostelium story

It was some 33 years almost to the date. There were three of us, partners in science; Srinivas V., Vinay T, and myself. We had just read this wonderful book on slime molds by William Loomis and we simply had to see this form of life. The Ruia college microbiology department is an unusual one….
