After a broken neck left him quadriplegic, Ian Burkhart was told he would never be able to use his hands. Now he can grasp a bottle and pick up a credit card by using a computer plugged directly into his brain. Special software is able to decode his thoughts and convert them into electrical signals in his hand, bypassing the damaged nerves in his spine. Now Ian has regained an amazing degree of control over his hand, each movement stimulated by his own thoughts.

A French photographer has conducted an interesting experiment in Gabon by installing mirrors in several locations in the wilds and observing the way the animals reacted to their own reflections. The result was most amusing, to say the least.

Here's what happens when you pour 1 984°F/1 085°C molten copper on a Big Mac. This demonstration has nothing to do with the fact that McDonald's uses preservatives in its ingredients. This is simply a demonstration of the Leidenfrost effect - a scientific principle explaining the phenomena that occurs when a liquid comes in near contact with a solid that is significantly hotter than its boiling point; the surface of the liquid comes to a nearly immediate boil, and creates a thin layer of protective steam. It's much the same effect as when one drops water onto a hot pan and the droplet is seen to dance across the surface. In this instance, the inherent moisture in the burger protects it for a few moments before the copper (at nearly 2 000 d ...

It's hard to fathom the difficulties our ancestors had to contend with given how our world has advanced with technological sophistication over the past century. We shouldn't, however, underestimate the power of the human-mind, and how everything that was discovered in the past paved the way for the practices used today, especially those used in science.

Of the very first astronomers, the ancient Babylonian were the first to use simple arithmetic to predict the positions of celestial bodies. Evidence reveals that these astronomers, working several centuries B.C.E., also employed sophisticated geometric methods that foreshadow the development of calculus. Historians had thought such techniques did not emerge until more than 1400 years later, ...

The blue-capped cordon-bleu (Uraeginthus cyanocephalus) has a special talent. Not only can it sing, it can shake a leg or two. For its courtship display, it holds a piece of nesting material in its beak, points its head upward, moves up and down, and sings. Both males and females bob and sing like this, and choose their partner. Now, researchers have found that as the bird bobs, it does a quick tap dance where it stomps its feet.
