Do bacteria collide with each other while swimming?

On a hot day in a busy swimming pool, I am often clumsily found paddling my way bumping into people. So it’s obvious to ask – do bacteria swimming around in water collide with each other. This is not such a simple question after all. Offcourse it should depend on how many bacteria are present…

Foldscoping from Cold Spring Harbor Lab #CshlComp meeting

Sometimes, thinking hard about models and theoretical frameworks for cell biology – our mind can drift to go and see what’s lurking right outside the conference room. I am at Cold Spring Harbor Lab at an incredible computational and modeling meeting; and I could not stop myself to take a walk At night and explore…

Embryonic development of human lice

If you have kids, you probably already know all about lice. Or maybe you think you know all about lice – and you just want to crush it. But wait, just wait a second, pull out your foldscope next time anyone talks about lice and give it a good strong look. And you can crush…

Magic in a bottle

In rushing through life; we often forget to see how strange and wonderful and magical our world actually is. With videos and photo capturing technologies – some of that magic can be shared. But it can not always be experienced the same way when you hold it in your hand. Today is one such example…

A flagellate morphing it’s shape – Distigma proteus

What an incredible flagellate did I stumble upon Today, while wandering through my favorite hiding spot; a swamp. I believe this is Distigma proteus – what’s remarkable is the body shape change which was continuous. If you watch is carefully; a remarkable transformation is happening. I am trying to isolate as many of them and…

Spittle bugs under a foldscope

I took these videos almost 3 years ago, but somehow forgot to post them here. Here are live spittlebugs that make bubbles, lots and lots of bubbles! And here is the same bug; but filmed at 240fps. Those are some fast bubbles being formed. Cheers Manu

Foldscoping at Beach in Ventura, CA

The smiles truly tell a special story. In the conversation, I also proposed a little project to explore whet determines the frequency of gill beating…

Foldscoping snow

What a way to start 2019 – it was snowing all morning; and I tried to foldscope snow. Here is a quick tutorial. It’s beautiful how the snow flakes melt! More soon. Enjoy the video. Now, here is a puzzle. Why does the snow flake melt as soon as we start imaging them. Leave comments…

Symbiosis continued – what’s inside a gut of a termite

We just finished running a foldscope training workshop for Exploratorium staff; allowing them to bring microscopy access to people outside the Exploratorium. I am thrilled we got to play with a termite and finally imaged ciliates living in the gut. Enjoy the video – I will post more videos from field collected samples. If you…

Dinoflagellates-cnidarian symbiosis in an upside down jellyfish – Cassiopea xamachana: Or “how to do science at a poster session and find a real life popeye”

I had the incredible fortune to meet a phenomenal postdoc Dr A. Ohdera at the lab of Dr. Y.Zheng (Carnegie institute, Baltimore) at ASCB (American Society of Cell Biology) 2018 meeting (poster number B786). Amongst thousands of posters – what struck me is that Dr Ohdera – who studies a unique symbiotic relationship between a…

How to geo-tag your Foldscope post using novo-map plugin

All, We have been planning to enable the mapping feature on all foldscope posts for a while – and I finally got around to testing some plugins; so now all of us can mark exact location of where the samples were collected. That’s important, when you discover a new species, new habitat, want to run…

Moment of uncovering root Rhizogenesis at Tamales Bay, Marconi Center beach

I love foldscope moments – since things happen that are hard to predict. This is a collection of Stanford faculty (from Biology, Bioengineering, civil etc.) all hanging out at the beach Foldscoping – and suddenly we uncover a beautiful phenomena. Sorry for the clicking sound on my phone; but enjoy the “aha” moment. Here is…

Micro snails in Puerto Rico

Joy of Foldscoping on a boat

Thibaut (foldscope super user) and I had a chance to spend some time in India; taking foldscope to some extreme locations. I have been meaning to write a detailed post on all our adventures in India – which I will get to soon – but in the mean time, enjoy this pleasing video of a…

Marine bacteria in a night Plankton tow

Ocean is vast and mysterious in so many ways. Sometimes I find it hard to just imagine such a large interconnected ecosystem with all its living abundance. Combine that with its inaccessibility simple by being completely under water. You can take a casual stroll in a rainforest day in and day out – to be…

Foldscope at Morgan State, Historically Black College

I want to quickly introduce the foldscope community to two remarkable individuals I met at Microscopy and Microanalysis 2018 meeting in Baltimore. I was giving a morning talk and accidentally I flipped to see the abstract book a night before. Hidden in that book, I was thrilled to find an abstract from Dr Frank and…

Science at Bar SZ Ranch

I had the privilege of staying two days at a ranch, with our host family at Bar SZ Ranch in San Benito County in California (https://www.barszranch.com). It’s an incredible place to just get lost in the woods, surrounded by farm animals and live a farm life for a few days. What I was delighted to…

Foldscope on Tara

I had an incredible time staying a short time on Tara. What an incredible gift to the scientific community. Wonderful boat filled with wonderful people. Got a chance to train kids and Tara staff on Foldscoping. The boat is off to Mexico and Panama; with an incredible diversity of oceanic life. Thibaut from the lab…

Friends from Latin America, After a month of planning; Team Foldscope is off to Latin America. This has been a long time coming; with partners around the world. It just took us some time to gather together the resources to make a big trip (thanks for all the support). In this first round, we will…

Watching individual bacteria in a 300 year old pond

Sometimes; wonder awaits you in seemingly quiet places. Walking up to a 300 year old pond that is fed by a stream under water is one such quiet place. But a lot is happening in this ecosystem that’s right below the surface. A quick drop of water fro here into my foldscope – and you…

Diversity that boggles our minds – polychaete worms

Photo: “A variety of marine worms”: plate from Das Meer by M.J. Schleiden (1804–1881). In 15 minutes of looking at the same rock I collected on the beach, I found more than 12 different species of polychaete worms. Some of them were swimmers; wriggling in the water column. Some of them had fans, others appendages…

Bryozoa saga continued – part 2

If you saw my previous post; I am stuck looking at billions of sargassum leaves on a beach – and Bryozoa covering almost all of them. See here. So I started poking in the water in hope of catching some fresh macroalgae to show up.. and after some adventures – did get some on my…

A floating partnership – Bryozoa – Akumal, México

As humans, we all value a piece of land to call home. It’s not so different sometimes in the ocean. Many invertebrates would colonize just about any surface you can find in the open waters. And Bryozoa are masters of colonizing just about anything.. even if it’s a floating algae. I am on a peninsula…
