Do Raccoons Wash their Hands Before they Eat?
We wash vegetables before cooking it. And we wash our hands before we start eating. That is because we have been told that washing would clean our food and that cleanliness is necessary to keep diseases away. But, have you seen cows, dogs or cats wash their food? They don’t. But there is one kind of furry mammals called racoons, which wash their food before eating. And it has been noticed that racoons refuse to eat if they cannot find water around....
The Spectacled Bear
Many of us wear glasses when we have problems with eyesight. But, have you ever heard of bears with glasses? No, not the bears who appear on the Cartoon Network on TV. Real bears.

Why do Some People snore More than Others?
If you ever slept in a room with an uncle or an aunt who snores, you would know how annoying it can be. The person causing all the noise sleeps like a log, while the room partner spends the night tossing and turning; waking up bleary-eyed the next morning. Did you know that snoring is a common ailment all over the world? Believe it or not, but on an average one in every four adults snores, says the website sleepquest....

What's Biting the Flea?
Scratch, scratch scratch goes your pet dog or cat. Behind the ears, on his body. He whips about trying to chew up his tail. What’s eating him? You part the hair and feel around. It’s a flea! Fleas are parasitic insects that suck the blood of birds and mammals. There are over 2,400 flea species worldwide classified under the order Siphonaptera. They are tiny wingless insects like the lice in our hair, either black or reddish brown....
What is Physiotherapy?
If you’ve ever been laid up in bed because of a broken leg, or with an arm in a cast, you’ll know how limp that limb feels when it is finally out of bandages. That’s because the muscles in that particular part of the body have not been used for so long that they’ve ‘forgotten’ how to function. They need to be re-taught their work, and this is where physiotherapy comes in. Physiotherapy is that branch of medicine, which makes use of physical agents or exercises to treat a disease or an injury....
Why do we Get Hiccups?
Hic! You’ve just hiccuped for what seems like the tenth time since you finished your big dinner. Wonder where these funny noises are coming from? The part to blame is your diaphragm, a dome-shaped muscle at the bottom of your chest, and all hiccups start here. The diaphragm almost always works perfectly. It pulls down when you inhale to help pull air into the lungs, and it pushes up when you exhale to help push air out of the lungs....
Does a Sloth Live its Entire Life Upside Down?
Imagine living your entire life upside down. Sounds impossible? Well, it is not impossible for a sloth. The sloth is a mammal which lives in South America. It spends most of its life on trees in an upside down position. Unbelievable, but true. Sloths eat, sleep, make babies and even give birth to their young ones in this position! But, don’t they fall off when they fall asleep, one might wonder. They don’t. A Sloth hanging upside down on the tree That’s because the sloth’s muscles do not relax like ours do when we are sleeping....
What is Ribotyping?
Consider this, in a murder case, the culprit has left no clues. There are no fingerprints or eye witnesses. A perfect crime, you would say. But on close inspection, the crime branch discovers a tiny strand of hair. Back in the forensic laboratories, scientists use this strand of hair to track down the criminal and solve the murder case. But, how can you crack a mystery with a strand of hair, you would exclaim. The technique used by forensic scientists to track down the culprit is called DNA-fingerprinting....
Why do we Yawn?
Do you think that a great big yawn means you are really bored? Well, if you do, then you cannot possibly be further from the truth. Until recently many researchers used to think yawning is essential to increasing the oxygen intake to the lungs. A few on the other hand insisted that yawning is similar to stretching as it increases blood pressure and heart beat rate. While both research findings are correct, new studies show that yawning actually perks you up instead of doing the opposite (as many of us seem to think)....
