First Experiments with Foldscope

Today was my first attempt at using the foldscope to visualize scale structures, and overall I would consider it a success! Because most of my recent experiments have been focusing on Vanessa cardui, the painted lady butterfly, that was the species I began with. Putting together the foldscope I found the design quite clever and…

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. …

Foldscope Workshop in the Peruvian Amazon

I recently had the pleasure of teaching a Tropical Entomology course in the Peruvian Amazon over winter break (this was through an organization called Field Projects International https://fieldprojects.org). Thanks to Manu and the Foldscope team, I was able to bring down several Foldscope units for my students. In addition to teaching them about topics ranging from ecology to…

Queen Ant wings

  A few days back ,I saw ants near the door and an insect with wings that  i belive  the Queen ant (motionless). Then I saw that the wings were different there were colourless patches in some area . First time in my life I wilfully plucked a wing ,gave me chills though it was…

Foldscope Findings!

                  Foldscope Findings!                                By Joseph Alejandre and Charlie Ortega          Hi everyone, hope you’ve had a blast looking at things under a microscope! We have too, and we’re excited to share our findings with you! We are 8th graders attending Loyola Academy, which is dedicated to the teachings of biological science.  This led…

Foldscope at Hackaton

  A couple of days ago I attended a Hackaton in Mendoza, Argentina. The main objective of it was to tell everyone what the Foldscope is and its possibilities. A lot of people were interested on the device. After talking a lot, we came up with the idea of an automatical image taking machine. So, we…

Microfluidics: a primer

This post is going up a little before I’d like, in that I’ve made a few steps towards a tool for the Foldscope, but the tool isn’t easy to use or refined yet.  A teacher I work with outside of Denver, Colorado that does an amazing job of letting students really taste whats its like…

Quail Hollow Ranch County Park pond critters

On July 10th I met up with Christian Schwarz and Tony Iwane at Quail Hollow Ranch County Park in Santa Cruz County, CA to do a dry run of what we might find if we did a public event for the community around the microscopic world of the park. The Park itself has some interesting biology…

Brine Shrimp in SF Bay

First time using the WordPress app: On my way back from helping a high school in Menlo Park with SDS-PAGE gel imaging I stopped off at Bedwell Bay Front Park to check out some of the salt ponds. The super salty ponds didn’t have any obvious signs of life but I did find a pond…

Surveying store supplements

Algae based supplements have become relatively common in the American market over the past 10 years and I’ve always been curious to assess 1) Is the organism on the label the same in the container? 2) Is the organism on the label the only organism in the container.  At Wholefoods in Berkeley I purchased the…

Diatoms of Clear Lake, CA

I recently went to my brothers graduation in Chico and on the way home took a little detour to visit Clear Lake, California, hypothesized to be one of the oldest lakes in North America at 480,000 years old according to USGS. The lake is teaming with life and in the summer gets deep green with…

Need help identifying an organism? iNaturalist may help.

I love finding new critters with my Foldscope. I love even more being able to name the new critters I find as a name allows me to search the internet and learn so much more about the organism. As humans we love to name stuff as it informs our imagination as much as it does…

Fungus on a fly

Today while trying to do emails at home with the windows open I had a fly buzzing around and I gave swipe at it which in most cases does nothing but move the fly out of my general space for a few minutes, but today my flailing finger actually made contact with the insect. I…

Using the Foldscope as a Cervical Cancer diagnosis tool

Yesterday we came to Stanford to start working on out on the implementation of the Foldscope as a Cervical Cancer diagnostic tool. Jeel exposed a conference about how to detect Cervical Cancer and we answered questions from the team. He also presented the Eco-Pap. The Eco-Pap allowed the diagnosis of cervical cancer with an environmental performance,…

Polychaete from Lake Merritt

I love Lake Merritt in Oakland and its the reason over 10 years ago that I decided to stay is the decidedly urban environment. It also happens to be ground zero for the study of Marine Invasive species. A high school kid at the time by the name of James Carlton in 1962 was curious…

Protozoan parasitizing a mosquito larva ?

The Sierra Nevada of California right now is blooming. The hills are brushed in the purple, golds and yellows of the California floral palette and beneath the old firs massive bolete mushrooms are pushing up through the duff, nearly asking to find themselves on a dinner plate. Water is abundant and where it has pooled,…

Image Composites – starfish

Some critters I want to look at are just bigger than the lower magnification lens can handle, so taking a tip from Tom Hata’s post https://microcosmos.foldscope.com/?p=10552 I decided to try my hand at stitching together a series of images in GIMP that were taken with the Foldscope. I went after a 3 mm brittle star…

Mosquito larva ?

I just assembled my Foldscope two nights ago and because of work hadn’t had a chance to go in the field and find something, so I decided to look at what might be growing in a bath water recycling system I have on my porch. I was expecting to find the usual suspects that I…

Compounding a foldscope

Here is a problem that might adorn entrance examination tests someday. It originated in a dream that I had a few days ago. I suspect this dream was inspired by the SLR hack of the foldscope. The low power lens of the foldscope can magnify objects ~140 times. The low power of a typical compound…

A simple microfluidic device and time lapse imaging of embryonic stem cells

One thing that is overlooked in our general understanding of cell biology is how dynamic everything is. During school, you are taught that cells are a tiny round blobs full of even tinier factories performing various pre-defined functions. These cells are each of a certain type and shape and combine to form greater structures that…

Arthropod Soil Biodiversity and Foldscope-DSLR Camera Hack

It has been a while since my last post on butterfly wing scales – since then I’ve been thinking up some directions to apply the Foldscope to a more in-depth study on biodiversity in the Amazon rainforest. When I initially played with the Foldscope in the jungle, I had the idea to take one scoop of soil to see what…

Question about High Magnification Lens

I have troubles getting centered image when using the High Magnification Lens. The image is always side-shifted and I don’t know if the problem comes from the lens assembling. On the other hand, with the LML the pictures are centered: All pictures are a fly wing.
