Space Age To Surgery EquipmentThough robots were once the stuff of Star Wars and The Jetsons, commercially available systems have made robotic surgeries common in hospitals. Located just feet away from the surgeon, the systems are minimally invasive and offer surgeons better dexterity.
Department of Defense-funded scientists want to take that capability to the next level so surgeries can commence on battlefields with the surgeon's work being done by a robot that's miles........Go to the Media-blog (Added on 8/23/2006 6:48:06 PM)
Seeing the InvisibleBy observing a rare head-on collision of galaxies at 10 million miles per hour, astronomers have made the first direct detection of "dark matter"--the mysterious, invisible stuff that comprises at least one-quarter of the universe.
Researchers have known for 70 years that there is much more mass in galaxies than can be seen. For example, spiral galaxies rotate at speeds that are only possible if the total mass of the galaxy is several times........Go to the New-technology-blog (Added on 8/23/2006 6:00:11 PM)

New Methods for Screening NanoparticlesResearchers at the U.S. Department of Energy's Brookhaven National Laboratory have developed a screening method to examine how newly made nanoparticles - particles with dimensions on the order of billionths of a meter - interact with human cells following exposure for various times and doses. This has led to the visualization of how human cells interact with some specific types of carbon nanoparticles. The method is described in a review........Go to the New-technology-blog (Added on 8/22/2006 5:07:15 AM)
First Direct Evidence For Dark MatterAstronomers have discovered first direct proof that dark matter exists.
University of Arizona astronomers and their colleagues got side-on views of two merging galaxy clusters in observations made with state-of-the-art optical and X-ray telescopes.
"Nature gave us this fantastic opportunity to see hypothesized dark matter separated from ordinary matter in this merging system," said UA astronomer Douglas Clowe, leader of the study.
