Wet-mount preparation of red alga from Monterey Bay

I love to I.D. algae in the intertidal, but red algae can be especially cryptic.  Here I am preparing my sample with a glass slide, and a glass slip that I am holding together with some Scotch tape so that I can wiggle it into place within my foldscope. The water in my wet mount…

Hacking A Lower Powered Foldscope

Recently, I decided to undertake a search for micrometeorites (you can read more about them here). Since a good portion of micrometeorites are ferrous, you can use a magnet to search for them. However, not all samples of ferrous particles are potential micrometeorites, so you  will have to examine them. I already have a handheld…

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…

Canterbury bells

The Canterbury Bells also known as bellflowers are absolutely beautiful. They come in shades of blues, purples, white, and pink. I first took a look at the sepal of the flower and noticed something very interesting. The sepal looked like it had hair on it. Just as Flies have protecting hair on its legs it…

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…

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…

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…

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…

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…

Observing Pollen of different flowers

We at our Pratham Science Exploratory observed pollen of different flowers also found that the number of pollen vary in different flowers. Some flowers have a lot and others have a few.

Exploring Stomata- Pratham Science Program

There are variety of leaves around us. I tried exploring Stomata in leaves of different plants, one each day. This was a wonderful experience knowing and observing plants around our center.        

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…

Algae

Received a foldscope today from a friend. Here’s the first photo I took of some algae using the lower res lens.

Exploring the Deep Blue Sea

Sometimes an awesome opportunity presents itself to you. That’s what happened to our class at the Lucile Packard Children’s Hospital School. Dan A., one of the shark divers from the Monterey Bay Aquarium, got connected with one of our teachers (Kathy H.) about bringing an aquarium-like learning experience to our hospital school students. He brought…

Hiking the Tankwa Camino with Foldscope

From 29 Sept to 9 Oct 2016 I took part in a 260km ‘Tankwa Camino’ endurance hike,  which stretches through one of the most desolate regions on earth: South Africa’s Tankwa Karoo. For 10 days our group of 50 hikers covered distances of up to 32kms per day while facing scorching temperatures. My Foldscope was…

Oh, what’s that growing inside my foot. Story of Tunga penetrans 

When you cross through an airport security line; you are often asked if you are carrying any insects or plants. Knowingly, we are not carrying anything back – but what about biodiversity traveling back with you unknowingly. This is the story of Tunga penetrans; one of the smallest fleas that recently hitched a ride in…

Impatiens balsamina

Admiring beauty of these flowers just couldn’t resist studying under foldscope!🙂 Petals: Leaf: L.S. Leaf: T.S. Stem:                                               Section through bud:               Anther:        …

Life Under The Origami Microscope : Our Early Tryst With The Foldscope

We are grateful to Professor Manu Prakash and his Foldscope team at Stanford University for sending us the set of foldscopes. In a short span of time, our SPIE Techno India Student chapter members have assembled the instrument and have started looking at various objects through the Foldscope. We are all having a really enriching…

Foldscoop 1:3. Long-term Lichen suspensions

Laziness is a good thing; sometimes. Previously I had posted on observing tardigrades, ciliates and nematodes (1, 2)  in Lichens. It so happened that due to a hundred obstacles that life so often places, I  forgot to observe the lichens suspended in mineral water for about two weeks. By this point, the water turned dark brown…

Stamen of a Hibiscus

The Macroscopic picture The  pollen on the anthers held up by the filament.   The pollen.

Pistils and pollen

In Bethesda Maryland, along the columns that grace the main atrium of the Howard Hughes Medical Institute headquartes, climbs a green vine decorated by violet flowers.  We took one of the flowers and proceeded to remove the pistil to observe in the  Foldscope.  This is my first, and quite likely not the last observation I…

Foldscope in Ratnagiri- India (Maharashtra)

Hello Everyone, Recently,I’ve been on a trip to my village Ratnagiri and I decided to take the foldscope along. It was awesome.Sadly, I haven’t been able to take pictures of a few observations but I have tried to get many of them.This is going to be a long post so I better type less. Enjoy…

Onion peel and insect parts

Hi everyone, First of all, thank you Manu for creating such a wonderful device. It would be very useful to use foldscope in diagnosing deadly diseases on-the-go. Me and Shree are 2nd year MBBS students at ‘Sri Dharmasthala Manjunatheswara College of Medical sciences and hospital, Karnataka’. We were very excited to receive our foldscope. We…
