Let’s explore more of the life in an ‘organic’ pond, continuing with the same water sample that we investigated for the last post. I now noticed a larva, about 5 mm long, swimming in the water. It was moving very fast, but I patiently followed it with a dropper and was finally able to pick…

Foldscoping on the streets of Addis Ababa
Sipping from boiling pots of coffee on cobbled meandering streets, with a coffee shop every step along – is not a description of some old block in Paris but the heart of Addis. Addis Ababa – the capital city of Ethiopia, the land that actually discovered Coffee and shared it with the world. A country…

Life in an ‘Organic pond’ – Part 1
After my experience and learning with the Dal Lake water sample, I have been constantly on the lookout for water ecosystems. Recently, I visited my sister’s home at the ‘Organo Eco-Habitat’ in Hyderabad, where there is an artificial pond. I collected water from a corner of the pond, in which I found an insect wing…
ON A VENTURE THROUGH NATURE
IN THE MIDDLE OF THE FOREST Students exploring the Empty Honey Hive which fallen on the ground explored the 200-year-old Baobab tree with a circumference of 14 m, planted by the French. The tree is an African species grown in Madagascar, Australia and Arabia collecting samples for foldscope photographing and viewing the honey comb explored...
ECOSYSTEM OF A POND

Granite pebble stone from Merced river in Yosemite
By using the magnet tapped to the camera of my phone to connect only the lens module of the foldscope, I enabled a way to image the surface of the pebbles. Interestingly, I have seen some very fragile while structure. By breaking the pebbles, we can see an incredible difference outside/inside in terms of color…
Tiny Creatures under Foldscope, that has bloomed my Mind.
While working on these algal culture what i have observed that, there were lots of algal diversity in mats and wall scrapped sample, and these different habitat include different algal diversity ranging from coccus to filamentous forms.
Moldy growth on bread explored by Botany students of GGDSD college, Chandigarh @ workshop
After the demonstration session on usage of foldscope, the students set to use foldscope on there own. One of the students procured sample of stale bread from mess and studied under foldscope.

Mysteries of Dal Lake, Kashmir – Part 2
After seeing the diverse flora in Part I, here I share the findings on the microbes in the water from Dal Lake. We thought we could find a dense composition of organisms if the water could be centrifuged. Sayantan, a graduate student in biology at TIFR Hyd helped me with this. We put 50 ml…
Mysteries of Dal Lake, Kashmir – Part 1
It all started when my friend got a water sample from Dal Lake, Srinagar. The ecosystem of Dal is ecologically rich with 117 recorded species of hydrophytes and phytoplankton. Here are some views of this beautiful Lake: wonder what we can find inside it, under the Foldscope! In my first observation, I saw many microbes…

Green Algae
Closterium cells are crescent-shaped or elongate and lack spines. Some are quite straight and needle-like, while others are much broader with curved ends. The ends of the cell are usually tapered and may be pointed or rounded. Each semicell has a single axial, ridged chloroplast with at least one pyrenoid Place: SINGERBAND VILLAGE DIST. CACHAR…
Blue Green Algae
Anabaena is a genus of filamentous cyanobacteria that exist as plankton. They are known for nitrogen-fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern. They are one of four genera of cyanobacteria that produce neurotoxins, which are harmful to local wildlife, as well as farm animals and pets. Production…
Blue Green Algae
Scytonema is a genus of photosynthetic cyanobacteria that contains over 100 species. It grows in filaments that form dark mats. Many species are aquatic and are either free-floating or grow attached to a submerged substrate, while others species grow on terrestrial rocks, wood, soil, or plants. Scytonema is a nitrogen fixer, and can provide fixed…

loeothece Valve slightly sigmoid, linear-lanceolate, with subacute ends, 55-85 µm long, 8.5-12.5 µm wide. Raphe sternum with single curvature, raphe angle +4 to +8°, practically median throughout. Central raphe fissures oppositely deflected dimorphic crooks, difficult to see in LM. Terminal areas very small triangles in semilateral position. A small apical microforamina segment is present at…
Green Algae
Coelastrum Thalli forming 4, 8, 16, 32 or 64 (-128) celled coenobia to ca. 100 &m diameter, organized as spherical, pyramidal or cuboid, free-floating colonies. Cells more-or-less densely alligned but usually with empty spaces between wall interstices. Cells globose, ovoid, or pyramidal 2-30 &m in maximum dimension. Cells joined at edges by specialized wall plaques…

Oscillatoria is a genus of filamentous cyanobacterium which is named after the oscillation in its movement. Filaments in the colonies can slide back and forth against each other until the whole mass is reoriented to its light source. It is commonly found in watering-troughs waters, and is mainly blue-green or brown-green. Oscillatoria is an organism…
Fresh Water Diatom
Gomphonema Colonial cells that form on branched muscilage stalks that are attached to a subtrate. In girdle view the cells are wedge shaped with an enlarged head at the opposite end of the stalk. Cells have one large plastid that lye mostly on one side of the girdle, but do extend partially onto the other…
