That's Impossible - Eternal Life

So once again, we have a documentary about longevity. It is produced by History Channel and one of the commentators is the editor of Scientific American so I guess it gives it a bit more credibility which it certainly needs because of many SF-like topics in it. Some of the things they talk about are really eye opening, especially the nano-technology which is already being used in the laboratory experiments. All in all, very informative and recommended.

Living Forever: The Longevity Revolution

Immortality. Life Extension. The Fountain of Youth. Real science or simply wishful thinking? Is it hope or is it hype? Scientists from around the world are racing to answer one of humanity's chief questions: can we turn back the human clock?

A decent documentary about the current researches in prolonging life expectancy. Several very interesting and promising methods are introduced along with the already popular caloric-restriction diet of which I am really no fan.
Enjoy.

Can we make a star on Earth? - BBC Horizon

Brian Cox from Manchester University discuses the possibility of making a star here on earth, a process known as nuclear fusion. Creating fusion on Earth was done a lot of times, in the explosion of a hydrogen bomb, however it is an uncontrolled process , therefore extremely destructive, controlled fusion is a different story all together. If successful, a controlled nuclear fusion would solve most of our energy problems as it provides massive quantities of energy from an extremely cheap and abundant fuel, hydrogen.

This documentary gives us a brief history of the web, from it's beginning to present day, including all the major events such as the over-inflated dot-com downfall. It also features the interviews with the key players of the internet revolution. Worth a watch.
