Snake-like Robot Could Assist SurgeonsDrawing on advances in robotics and computer technology, Johns Hopkins University researchers are designing new high-tech medical tools to equip the operating room of the future. These systems and instruments could someday help doctors treat patients more safely and effectively and allow them to perform surgical tasks that are nearly impossible today.
The tools include a snakelike robot that could enable surgeons, operating in the narrow........Go to the New-technology-blog (Added on 12/20/2006 7:19:06 PM)
2.2 Million Years Old Ape-man SkeletonLiverpool researchers worked in collaboration with colleagues at the University of Leeds to analyse the skeleton, which was found in 1997 in Sterkfontein cave in South Africa. Known as 'Little Foot', it was known to be between two million and four million years old, but the team has now dated it precisely to 2.2 million years old.
These new findings reveal that the ape-like creature - part of the Australophithecus africanus family - may not........Go to the Media-blog (Added on 12/18/2006 9:42:48 PM)
Top 10 Myths About EvolutionThough the United States is the world leader in science and technology, a number of of its citizens display a shocking ignorance regarding basic scientific facts. Recent surveys have revealed that only about half of Americans realize that humans have never lived side by side with dinosaurs, and about the same number reject the idea that humans developed from earlier species of animals.

Stem Cells Help to Renew ThemselvesStem cells are not fixed as to their potential development (pluripotent). Thus, stem cells from embryos may one day be able to help to manage or cure many different diseases. Initially, however, scientists want to keep large numbers of pluripotent cells in the laboratory which then differentiate into specialised cells. This is the only way they will acquire a sufficient quantity of specialised cells which might be used for therapeutic purposes.........Go to the Science-blog (Added on 12/15/2006 5:01:53 AM)
Making Dark Matter VisibleAs light travels to us from distant objects its path is bent slightly by the gravitational effects of the things it passes. This effect was first observed in 1919 for the light of distant stars passing close to the surface of the Sun, proving Einstein's theory of gravity to be a better description of reality than Newton's. The bending causes a detectable distortion of the images of distant galaxies analogous to the distortion of a distant scene........Go to the Astronomy-blog (Added on 12/15/2006 4:55:58 AM)
Feet, rather than fistsFeet, rather than fists, are the most dangerous bodily weapon available, reveals research on violent assaults, reported in the journal Injury Prevention.
