What kind of Family Life did the Dinosaurs Have?
In Argentina this year, scientists digging on a site made a fantastic discovery, which made them realise that dinosaurs lived as a large family. The site consisted of many nests with each nest containing as many as 15 to 30 eggs. The eggs belonged to a plant-eating dinosaur called Titanosaurs. It is the biggest nesting site of dinosaurs found so far. The word dinosaur is a Greek word meaning giant reptile. Most reptiles lay eggs in nests but they walk away after the young hatch to fend for themselves....
Which Galaxy is Visible to the Eye?
The sun we see everyday is just one of the thousands of stars we see at night. Such a huge collection of stars is called a galaxy. And the stars we see belong to a galaxy called the Milky Way. There are millions of galaxies in the sky, most of whom are hidden from our view. However, there are some galaxies which can be seen with the naked eye. The most famous and the brightest of these is the M31 or the Andromeda galaxy....
Why is Hair Today, Gone Tomorrow?
Here’s a quiz question: what is curly or straight and needs to be combed, brushed, plaited or twisted? It is gelled, shampooed, dyed, coloured black, blonde, white, red, brown and needs to be cut once in a while. A hint – the answer is above your head – it’s your hair! Each time you pass by a mirror, the one thing that strikes you is the hair on your head. Hair is something that grows by itself without any help....
Who Sold the Eiffel Tower Twice?
There have been conmen and cheats, cardsharps, and crooks but when it comes to deception and trickery few could match the style of international conman Victor Lustig. Victor Lustig was the king of conmen with forty-five known aliases and nearly fifty arrests in the United States alone. He was born in 1890 in Czechoslovakia. Though brilliant as a child, he turned to a life of crime, excelling in gambling, card games and scams. Lustig became a riverside gambler plying the various cruise boats that invariably consisted of the rich and famous....
Why do Some People Stutter?
Rahul is a lonely child. He is laughed at because whenever he speaks, he stutters. He goes “my name is Ra-Ra-Rahul.” His mother and grandmother thought it was because he had a short tongue. Other people said it was because, as a baby, Rahul’s hair was cut before he spoke his first word. Finally, Rahul’s mother took him to the doctor. She was told that it had nothing to do with these myths. Rather, Rahul had a speech disorder called dysphemia....
Are Fish Dumb?
There was a time when people thought that fish were dumb creatures. Until they invented machines which could detect sounds under water. And guess what these machines heard? A string of grunts, clicks, thumps and other kinds of sounds. It was the fish doing a lot of underwater talking! It seems that they have a lot to talk about, for each sound has a different meaning. There is a kind of fish called the croaker. They actually croak like a frog!...
Who was the US President for a Day?
Quick all you quizzards and prospective Who Wants to be a Millionaire candidates: Who was the eleventh, twelfth, and thirteenth Presidents of the United States? James Polk, Zachary Taylor, Millard Fillmore . .? Yeah, but what about David Atchison? Wasn’t he sworn in after Polk? So shouldn’t Atchison be the 12th president and not Zachary Taylor? Yes. It’s true. There was a gap of a day between Polk stepping down and Taylor taking over. And Atchison stepped in as President – just for one day!...
What is Leukaemia?
Some 15 years back when I was still in school, our class teacher, Mrs. Khurana, would remain absent from school and class almost every other day. We kids were very happy without realising and neither did we bother to find out the reason for her absence. It was only later that our principal informed us that Mrs. Khurana’s only son was suffering from leukaemia (wrongly called blood cancer). I remember later that Mrs. Khurana took her son to abroad where he underwent a bone marrow transplant....
Why Do Knuckles Pop?
Have you ever laced your fingers together and bent your fingers back? If you pressed hard on any bent finger, you would have heard a popping sound? Finger joints produce that loud c-r-a-c-king sound. The sound comes when bubbles in the fluid around the joint burst! Our entire body is made of a skeleton of 206 bones. Bones help in giving shape and support to the body and help us move about. Our bones are not too long otherwise we would not be able to bend or grasp things....
Do Some Animals Farm?
We all live the way we do in villages and cities because a long, long time ago, the early humans gave up hunting for farming. They domesticated plant species by cultivation, ploughed the land and harvested the grain. That was the beginning of civilisation as we understand it. But, do you know that certain ant species were actually farming fungus years before humans learnt how to farm? For many millions of years, ants belonging to the attines group were farming and cultivating fungi in their anthill nests....
