You may forget where you have parked the car, what you did yesterday and the birthday of your best buddy. How many times you were trying to prepare yourself for an exam and you couldn't learn anything? If you're young, they say you're in love or your mind is wandering; with the age they say you've...
The first cephalopods ("head-foot") appeared 500 million years ago. They were shelled, just like their relatives, snails and clams. But later, in Devonian, Carboniferous, Triassic, and Tertiary Epochs, with the evolution of the fish, marine reptiles, and later whales, to survive, the shelled cephalopods had to retrea...
1. Skunks appeared 40 million years ago, evolving from common ancestors with the weasels and polecats (no doubt about the last ones...). They evolved only in the Americas, where they are still found today, from Southern Canada to the southern tip of South America. The oldest skunk fossils are 10 million years old (th...

Scientists have been puzzled by this odd anatomy. Echidna does not even use its penis for urination and it gets it out of t...

The ghost Bat (Macroderma gigas), also named the Australian False Vampire Bat, is endemic to Australia and i...
If you think that human evolution has just stopped, you're wrong. Not only are we still in the middle of a vivid evolution, but in 100,000 years, we will be split into two species: a sexy, intelligent power-detaining elite and an underclass of low intelligence, ugly dwarf humanoids.This is what Dr. Oliver Curry,...
Eventually, amphetamines destroy your teeth. Paradoxically, in such cases, dentists hold the secret of our salvation: and that's lidocaine, a drug usually employed to numb your gums. Lidocaine shuts off insula, a brain nucleus controlling drug addiction, and targeting the insula's activity could one day fre...
There are increasingly more cases in which the inner sexual feelings do not match the external genitalia. And it's not merely about sexual orientation. There are also numerous cases of ambiguous genitalia in humans, about 1: 4500 births. New discoveries are again underlining the fact that men have an XY pair of ...
