Experience with Foldscope

It was wonderful to directly observe the microscopic organisms live using foldscope coupled with cellphone camera. It was my first experience at ICGEB. I thank DBT organizers for giving me the opportunity to work with Foldscope.

Down feather with a polarizing filter

I took these pictures with my foldscope and used polarizers to do so.  The one with a pinkish background had both polarizing filters and a compensator device between them.

We have hair, they have things bizarre…

Animals aren’t unique when it comes to having things growing on their skin. Plants have an even bizarre set of things growing on their skin too, some of which secrete chemicals that are secondary metabolites. Foldscoping these reveal things about what ‘hair’ they have! Some of the explorations as follows : 1. Cucurbita maxima :…

Assessment of bull semen by Foldscope

I am an animal reproduction scientist and interested in improving fertility of dairy animals in India. Insemination by poor quality semen is one of the reason of repeatbreeding problem in cows in India. Foldscope will be a handy tool for pre-insemination quality evaluation of each dose of semen being used in the field for Artificial…

Karuvaipillai Pollen

Karuvaipillai (Murraya koenigii) is flowering now! Here is some pollen from the flowers: Here is the same pollen after a couple of hours in glycerol: (The black lines in the background are the 1mm grid — would be good to have a more detailed grid to allow for generating a scale bar….)

Fun time with fibres and other things

From the clothes we wear to the paper on which we write, these things are made of fibres. Fibres of polysaccharides. Just how amazing these look under a foldscope…   Paper may look smooth and uniform as viewed from the naked eye, but microscopically a different story is seen.     Cotton fibres seen through…

ASSETT and Foldscope: A marriage made in microcosmos heaven

The past 6 weeks or so I have been tinkering with Tetrahymenas thanks to the wonderful ASSETT program run by Cornell University. ASSETT or Advancing Secondary Science Education through Tetrahymena is an NIH funded program that provides modular science education material for schools, using Tetrahymena as a model system.  Each module is well designed keeping the…

Hematologia

He estado estudiando la morfología y las patologías de los eritrocitos en Medicina Veterinaria. Pero he tenido dificultades en cuanto al enfoque por lo que es una célula muy pequeña, mas sin embargo hare lo posible dar a conocer mis resultados.

Mosquito Claw

Like many other users a mosquito was annoying me, I killed her and viewed her anatomy under my foldscope.  After tweeting the focusing I finally managed to get a clear picture of her leg, wing, and most interestingly her foot pad. As you can see in the image mosquitoes have claws.  How cool is that?…

Captured rat skin section by Foldscope

I was really very anxious to see my histology slides after attending the Foldscope workshop organised in ICGEB by DBT on 16/04/2018. I am happy as I could focus the section with Foldscope and mobile, which I couldn’t do in the workshop. pressing the sample stage folds in mobile phone view, section get nicely focused….

Red hair? or parts of reproduction?

So, this time I am in a village area surrounded but trees, insects etc. I wandered arundel searching for a good thing to discover the wonders of. I found a fallen flower with a interesting looking stigma.so, I whipped out my foldscope. (Sorry, can’t focus better) BTW my stained blood pt 2 is due in…

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…

தஞ்சாவூரான் பூண்டு அல்லது ரயில் பூண்டின் மகரந்தம்!

  தமிழ்நாடு அறிவியல் இயக்கத்தின் மடிப்பு நுண்ணோக்கி பயிற்சியும்….  எங்கள் பள்ளி மாணவர்களின் ரயில் பூண்டின்(தஞ்சாவூரான் பூண்டு)  மகரந்தத்தூள் அறியும் முயற்சியும்…. கடந்த 8.4.2018 ஞாயிறன்று தமிழ்நாடு அறிவியல் இயக்கத்தின் மடிப்பு நுண்ணோக்கி பயிற்சி  மன்னார்குடியில் நடைபெற்றது. இப்பயிற்சியை மதுரையைச் சேர்ந்த மொ.பாண்டியராஜன் அவர்கள் மிகுந்த ஆர்வத்துடன் வழங்கினார். இப்பயிற்சியும், பயிற்சியின்போது வழங்கப்பட்ட ஒரு மடிப்பு நுண்ணோக்கியும் மிகவும் பயனுள்ளதாக இருந்தது. இந்தப் பயிற்சியின் தகவல்களை மாணவர்களிடம் கூறி அவர்களுக்கு மடிப்பு நுண்ணோக்கியை கையாளும் விதம் பற்றிக்…

First time using a foldscope: Amazing!!

Foldscope Discoveries Here in Squamish, BC at Coast Mountain Academy, we found charcoal from the fire pit. When we put a sample in our foldscope, we thought it looked very beautiful. Despite nothing moving around, it was a great first discovery. We look forward to using the Foldscope more to discover new things and change…

Life in a pedestal pond

Life in a pedestal pond Hyderabad was once a city of beautiful lakes and ponds and to some it still seems so. Our place-names record long-lost water — Gachibowli (well), Nallakunta (pond), Patancheru (lake), Chaderghat (riverside), and many more. As we continue to lose our water sources to urban sprawls we experience the seamy side…

Preparing slides for demonstrations

For fundraising and showing off Foldscopes I find it a great idea to have pre-prepared slides ready to go on the run! Here are a few examples I have put together. If you are looking to fundraise, there is no better way, than to put a foldscope in the HANDS of donors with ready to…
