Mosquito Menace
Guess what besides fat raindrops, rain clouds in Mumbai bring? Those tiny terrors, mosquitoes. Result: nights spent tossing and turning, and swatting the insects. But the next morning you wake up with those tell tale red marks on your arms, pause to think if you took a bath or not the previous night. That’s right. Human sweat turns mosquitoes on more than anything else. Research carried out by scientists in The Netherlands say that mosquitoes are actually quite finicky about whom they sting and never ever nibble at random....
Everything is made of something
How do you make tea? Simple, put a teaspoon of tea into a boiling cup of water. Strain the water, pour some milk and sugar to taste and the tea is ready! Interestingly, everything that we prepare has a recipe and is made up of simpler ingredients. For example, what is sugar made of? It is made of sugar molecules, which in turn, are made up of atoms. The atom is the building block of all substances....
All Human History is Just 10 Seconds Old!
Look at the dial of a clock. Imagine that the 12 hours showing on the dial are equal to earth’s history of four-and-a-half billion years. Now, this is how the earth’s evolution happened… We know very little about what happened in the first three hours of the earth’s existence. The first signs of life appeared in the form of bacteria when the earth was four hours old. Then came the first vertebrates (animals with skeletons). They were born when the earth was 10 hours and 35 minutes old....
Deception and Mimicry Among Animals to Fool Enemies!
All living beings have enemies. And they all have developed interesting ways to keep them at bay. Some animals hide, others run, or just fly away when faced with danger. These are their defence mechanisms. Some animals can hide without moving. They have the unique ability to change their colour to merge with the surroundings. They become invisible to the predator. This method of defence is called “camouflage”. Some rabbits change colour with the change of season....
Birds Which Eat Their Feathers
We all know that birds use their feathers to line their nests. But have you ever heard of a bird eating its own feathers? It is a bird which lives in water and is called the great crested grebe. It eats its own feathers and feeds them to her young ones too. And, it always prefers soft feathers, which it sheds throughout the year. Scientists believe that its feather-eating habit is linked to the process with which it throws waste....
A New Camel Specie Discovered
Have you ever sat on a camel? Well, if you have, then you know how scary it is when the camel rises on its long wobbly legs. The rocking motion of a camel is a bit like a ship being tossed around in heaving seas. Small wonder then that the camel is often called the ship of the desert. Actually, the name owes its origins to the fact that camels were brought from the desert, to serve as beasts of burden in other countries....
Great White Sharks Heading for Extinction
If you want a beach crowded with surfers and swimmers and other sun worshippers to empty out within a minute, cup your hands by the side of your mouth and shout loudly, ‘SHARK’ and wait for this miracle to happen. Because the very word conjures up images from Steven Spielberg’s movie ‘Jaws’. An image of a gaping mouth with rows of razor-sharp teeth and a greyish white shark thrashing around in murky water, grappling with its catch....
Antlers: A Deer Story
Trees shed leaves in autumn and snakes shed their skin once a year. In the same way, deer shed their antlers every year. Yes, those huge branches on antlers grow fresh every year. At any given point of time, a deer’s antlers will not be more than a year old. It is always the male deer which has antlers, except in the case of the caribou and the reindeer whose females also have antlers. It takes about two to three months for the antlers to grow to their full size....
Save rivers, lakes from worshippers
Before every Ganesh Chaturthi, people from across India, especially Maharashtra, Andhra Pradesh, West Bengal and Orissa, get busy with preparations for celebrations. But, as the momentum of activity increases, officials of the Central Pollution Control Board (CPCB) start feeling queasy in their stomachs. For, though festivals like Ganesh Puja and Durga Puja are a time for fun, it is also the time when rivers and lakes around the country are abused. Unlike in the past when the idols of gods and goddesses were made of ordinary colours and plain clay that dissolve in water easily, without causing widespread pollution, now they are made of plaster of Paris, distemper, plastic paint, dyes, metallic powders, adhesives, varnish, fluorescent powders and oil paints, which can have an adverse effect on the eyes, skin and respiratory system....
The Whale Hunt is On
Japan has sent out a fleet of ships on a two-month mission. Officials say that the expedition has a harmless aim: it is merely a survey to collect data on the Bryde, Sperm and Minke whales’ habitats, diet and migration patterns. The Whale Hunt is On [Illustration by Shiju George] But the environmentalists are up in arms against them. What has shocked them is the Japanese intent to catch and kill 160 whales....
