Young children of Jai Ambe Nagar, a slum near Mankhurd which comes under M Ward, know a lot of microorganisms but they had never seen a living microorganism before. Today that got an opportunity to explore the microscopic world with the help of a low cost paper microscope (foldscope) invented by Professor Manu Prakash. They…

Effective del cafe en los latidos de la larva del mosquito

0D0AE68B-F02B-42B8-AD2D-12ED5DA86AAA We did an experiment where we added coffee to a mosquito larvae. ALl of us thought that the heart beat will go up – just like when we drink coffee. Coffee has caffeine that is known to affect heart rate. We were all surprised that the heart rate goes down. So our hypothesis was…

Air particle test slide results

I volunteer teach 5th grade science and would like a protocol for monitoring the quality of air. How would it be done with fold scope? count particles? measure size? range of particle sizes? numbers with respect to time? A link that I can’t find again suggests a simple way of detecting 2-micron to 40-micron particles…

I could not identify the organisms just by looking at the broken parts but nonetheless it was fsdcfascina to see so many beautiful objects…

Foldscopy of a fish juvenile

Seagrass meadows are well recognized for acting as a nursery ground for many commercially important fish species. Nalabana, a bird sanctuary within the Chilika Lagoon supports dense seagrass meadows that act as sheltering ground for many important fish and crab species. A survey on seagrass meadows  was carried out during which some fish juveniles were…

Maple Syrup with Polarizing lenses

As winter approaches, the Maples’ leaves change colors. In a few months, as it begins to warm, the tree produces a sweet sap which is boiled down to Maple syrup, over 100litres of sap are boiled to make 1 litre of the sweet syrup. After sitting out for a few days, it dries. Here is…

Powder analysis of traditionally used medicinal plants with FOLDSCOPE

In this study, powder analysis of three medicinal plants which are used traditionally i.e., Onanthe javanica, Psophocarpus tetragonolobus, Solanum xanthocarpum and Tithonia diversifolia were performed. This will help in identification and characterisation of closely related species and also for prevention of crude drug adulteration. 1. Solanum xanthocarpum   Cork cells and trichome were observed  Multiradiate stellate…

Cuscuta: a parasitic plant

  Went for a morning walk and spotted Cuscuta. It is a parasitic plant which wraps itself around a host plant and survives on food produced by the host. I took a small section of it with a sharp blade and observed it under the Foldscope. Section was good enough to see different parts of…

Trichomes

Trichomes serve a variety of functions, depending on their location. As root hairs (and as leaf hairs in epiphytes), trichomes absorb water and minerals. As leaf hairs, they reflect radiation, lower plant temperature, and reduce water loss. They also provide defense against insects.

Pests on Chrysanthemum leaves

It is flowering season for Chrysanthemums in my garden. Some white powder was spotted on the leaves. Under foldscope some pests could be seen on the undersurface of Leaves. Are these Aphids or mites?
