Invisibility Cloak Swirls Closer to Reality
Ever wished you could have Harry Potter's invisibility cloak? Science, not magic, could make that a reality. Researchers at the University of California at Berkeley have created materials that have the potential to bend light and even redirect it around themselves, cloaking any object behind them. They are metamaterials, materials that gain unusual properties via their structures. While all materials found in nature have a positive refractive index, these man-made metamaterials have a negative one.

A Virus-Powered Battery
Engineers at MIT have figured out a way to deal with virus that is better than just killing them: they're putting them to work. The researchers have developed a new technique wherein a key component of a microscopic battery is assembled by viruses, allowing for the cheap and simple construction of very small power sources.

Going Up?
One of the most promising technologies for the aspiring outer-space commuter is the space elevator. The concept, like quite a few others, was pressed into the public imagination by Arthur C. Clarke, who in his 1979 novel The Fountains of Paradise described a incredibly thin, incredibly strong carbon filament with one end anchored on Earth and the other extending up to a satellite in geostationary orbit. Now, a group of Japanese scientists are convinced that they can build a space elevator more quickly and cheaply than has been believed possible. Such a cable could convey cargo into space very cheaply and easily. Carriages would travel up and down the cable under modest power, not the vast expenditures of energy that are currently needed to send anything into orbit.
11.26.2008 at 10:58am - Comment by Richardo CrispusSurely a better way to do it would be to have to have the wire "loop" around the satellite and go down to earth again and, as something comes up, ores etc and spacecraft would go down. As there would be ore etc coming down with the spacecraft that would mean that the energy require to run the elevator minimal. You may think this break the laws of thermodynamics but more stuff would be coming down than going up. This idea has been put forward in some of the "Science of Diskworld" books and "The science of Dr. Who" books. The minimal energy required to run it could come form helium-3 which could be mined on the moon. This isotope of helium would also be very useful in green generation of power
