Unresistible sweet Madras Thorn!

There is a tree that is liked by many animals, humans and insects. It is the Madras Thorn (Manila Tamarind, Sweet Tamarind, Pithecellobium dulce, 'Kodukkapuli' in Tamil). Goats are attracted by its leaves as they are tasty to them. Parrots, crows and squirrels find its pod as a sweet fruit. Children and adults too eat the pods as snacks. The pods that hang

Insects evolving to the world of fame!

Curious creatures are these ants, bees, wasps and termites. In and near every household of the world we meet one or more of them at any given time. All these come under one Order, Hymenoptera. There are much similarities than some dissimilarities among them. They are mostly social in nature and build colonies for themselves to dwell. Basically, in common (for example, ants) they have Workers, Soldiers, Kings (Drones) and Queens as members in their colonies. The Workers and Soldiers are sterile, wingless and are females; they develop from unfertilized eggs as diploid members. Winged males (kings or drones) are haploid and fertile!

Desiccants protect and preserve!

When there was a disturbance I was able to identify it to be a living thing - it ran away using its legs!

Koel is to sing its song here!

A bird falls down from the roof of the building onto its floor. It does not fly or run away. But simply sits down as if it is brooding with fluffed up feathers. This happened in the Physics Laboratory of my college in the year 1971! This white streaked bird is a chick of the Asian Koel (Cuckoo, Eudynamys scolopaceus, 'Kuil' in Tamil). At first I thought it to be a sick bird of prey. But later on I

Magic Golden bangles of Chemistry!

In my college Chemistry laboratory there are racks and racks of small reagent bottles containing various chemical solutions. As a curious chemistry student then, I used to see the reactions as when a reagent is added to another one or multiple reagents added to a single one in a test tube. It was really adventurous to note the various chemical reactions taking place - change of color, production of colored solution from colorless one, precipitation of solids as a magic from a solution and colored vapors coming out with specific odors! A wonderful reaction to which one of our lecturers

The mute FM Pocket Radio Receiver!

In the year 1970, I tried to tune in a new Pocket radio receiver. But I could not hear any voice or music with it as there was no radio station found in its band. The radio was a present from a German penfriend to my brother - in- law. But how can a receiver produce sound if ...

Spider Pill to cut Medical Bill!

Excitement awaits for doctors whenever something disturbs patient from within his abdomen. If his abdomen is cut open and viewed they could stop the disturbance; but the procedure is both invasive and risky. Now a less invasive and novel way to view the inner wall of intestine has been devised by the Italian Scientists using a small device called 'Spider Pill.'
