The US space agency Nasa has unveiled a model of a space telescope that scientists say will be able to see to the farthest reaches of the universe. The James Webb Space Telescope (JWST) is intended to replace the ageing Hubble telescope.read more | digg story

Astronomers have discovered a planet outside our solar system that’s so similar to Earth it might sustain life. Its temperature runs between 32 and 104F. It’s 14 times closer to its star (a red dwarf) than we are to the Sun, but the star, Gliese 581, is smaller and dimmer. The star is 20.5 light [...]
A pocket-sized device that runs on two AA batteries and copies DNA as accurately as expensive lab equipment has been developed by researchers in the US. The device has no moving parts and costs just $10 to make. It runs polymerase chain reactions (PCRs), to generate billions of identical copies of a DNA strand, in [...]
Electromagnetic “wormhole” results from turning invisible sphere inside out. Viewed straight on, light simply zips down the tube. But from the side, light would appear to come out of nowhere, as though sent on a detour to another dimension and back.read more | digg story
University of Wisconsin-Madison researchers have invented a machine that makes you sleep with the PUSH OF A BUTTON, then gives you the equivalent of eight hours of sleep in just two or three hours. The machine uses a technique called transcranial magnetic stimulation (TMS) to induce the slow brain waves associated with the deepest phases [...]
At the CTIA Wireless 2007 show, TI is providing public demonstrations of its digital light processing (DLP) “pico” projector, a tiny movie projector that can fit inside a cell phone.read more | digg story
In 2004, scientists unearthed a 400-pound fossilized top — or crown — of a tree. The following summer, the same team discovered fragments of a 28-foot trunk. Piecing together stump, trunk and crown now reveals what the full tree looked like for the first time.read more | digg story
Yes, the title is melodramatic, but researchers say newly found enzymes can remove A and B antigens from blood, converting it to type O, which can be transfused to anyone safely. This could be a major breakthrough in the blood supply!read more | digg story
