We zoom in towards the crowded central region, in the constellation of Sagittarius (The Archer). By shifting to an infrared red view we see through the dusty clouds in this direction and get a close up view of the objects orbiting the supermassive black hole that lies at the centre of the Milky Way. The final views show the motion of a newly-discovered gas cloud that is falling rapidly towards

From selective breeding to genetic modification, our understanding of biology is now merging with the principles of engineering to bring us synthetic biology.

This railway goes up and down a mountain in England, but it does not have a motor. Instead, each car has a 700 gallon tank of water, and the two cars are connected by a cable. At the top, the car that will be going down fills up its tank. As it falls, it pulls the other car up. At the bottom, it empties its tank so the other car can pull it up.

A "CNC mill" is a computer-controlled machine that can cut materials into new shapes. Lots of manufacturers use them to create parts, and "real" CNC machines cost as much as a car. This video shows a very simple, very inexpensive CNC machine so that, at a basic level, you can see how one works.

A "Smart car" is one of the smallest cars on the road today. When you buy one it has a small engine and can't really go that fast. The Ferrari is one of the fastest cars on the road today.So how can a Smart car beat a Ferrari? As you can see in the following video, looks can be deceiving. Because the Smart is so small and light, if you give it a powerful engine and totally modify the frame to

If you read the video description, it looks like this: "This is a solid-state Tesla coil. The primary runs at its resonant frequency in the 41 KHz range, and is modulated from the control unit in order to generate the tones you hear.So just to explain a little further, yes, it is the actual high voltage sparks that are making the noise. Every cycle of the music is a burst of sparks at 41 KHz,

Bridge collapses are very rare, so when this one happened in Minneapolis it shocked the nation. A big part of bridge design today is to build in lots of redundancy (extra strength) to prevent this kind of thing from happening. It is still unclear what caused this bridge to collapse:
