My Robot Robbi
Have you ever seen a robot? No? Meet my robot friend and philosopher, Robbi. To be precise, its name is Robbi-999XHA. You may wonder what is Robbi-999XHA. Just as cars, washing machines or xerox machines are of different models with different names, does this strange name also indicate something similar? Yes, you’re absolutely right! It is a particular domestic model of a robot. 999 stands for the year of its make — 1999, X stands for deluxe model, and HA is for home appliance....
Why Do we Get Tired?
Sumit was a tireless bundle of energy. He was always up to some mischief or the other. As he grew, to his mother’s relief he became a more relaxed child, and over the years his energy level seems to have come down considerably. However, now he feels tired and fatigued. At times he wonders why he gets so tired so soon when there is so much that he wants to do? What is it in our body that causes fatigue?...
Who's the Brainiest animal of Them All?
The next time someone calls you an ape or a bird brain, ask her to think again. Brain scans of animals have revealed similar patterns of electrical activity in human and animal brains, so obviously humans aren’t the only smart ones around. Who’s the Brainiest of Them All? The brainiest animals are chimpanzees, which share 99 per cent of the human deoxyribonucleic acid or DNA as it is known. (DNA is a chain of molecules within the nucleus of a cell that have all the genetic information influencing the characteristics we inherit from our parents....

As a child my day began with a LARGE glass of milk and five almonds with their skin pealed, that my mother used to put in a bowl of water the previous night. While the milk was for health and energy, the almonds were for increasing the memory. I don’t know how much they helped, but I still offer them to my children in the hope that they do. After all, memory is a precious thing....
My Ambition
My Ambition [Illustration by Shinod A.P.] Rishika Das Roy, who is from Kolkata, seems to be very determined about what she wants to become when she grows up. Sometimes I wonder what I would like to be when I grow up. I think of a different ambition every year. Since I turned eight, I would wonder what I really wanted to be. Would I be a teacher, a singer, a journalist or no, an astronaut....
Do Aphasics Make Great Lie Detectors?
Believe it or not but it is true. There are people who lose the ability to understand or use words due to brain damage. But they become extremely good at something else. They become experts at spotting liars. By the changing expressions of people’s faces and the tone of their voice they can make out lies from truth. The condition in which people lose their power to understand or words due to brain damage is called aphasia....
Birds Sing in their Sleep
Just like humans, birds too rely on sound to communicate. However, they do not have a ‘language’ in the true sense of the word and instead emit a variety of squawks and chirps to convey different emotions. Often, birds recognise their mates (or young) by sound rather than sight. Hungry fledglings use begging calls to let their mothers know it is feeding time. Alarm calls, flight calls for flight coordination, and warning calls are other sounds emitted frequently by the adults....
