Simulation Shows Bacteria Could Live on Mars

Sunday, December 7th, 2008

The possibility of life on Mars has been debated almost since the invention of the telescope. Annual growth and shrinkage of the martian ice caps and seasonal changes in color were observed by astronomers such as Herschel and Whewell in the 18th and 19th centuries. Late in the 19th century, Schiaparelli ...

Skin-tenna: Antenna That Uses Skin To Transmit Signals

Friday, June 20th, 2008

Researchers at Queen's University Belfast, Northern Ireland, designed a wireless antenna that channels signals along human skin could broadcast signals over your body to connect up medical implants or portable gadgets. The new power-efficient approach could make more of established medical devices like pacemakers or help future implants distributed around ...

Researchers Build Bionic Eye That Could Give You Superhuman Vision

Sunday, June 8th, 2008

Movie characters from the Terminator to the Bionic Woman use bionic eyes to zoom in on far-off scenes, have useful facts pop into their field of view, or create virtual crosshairs. Off the screen, virtual displays have been proposed for more practical purposes -- visual aids to help vision-impaired people, ...

Research: Bacteria Capable Of Generating Electricity

Tuesday, March 4th, 2008

Researchers at the University of Minnesota studying bacteria capable of generating electricity have discovered that riboflavin (commonly known as vitamin B-2) is responsible for much of the energy produced by these organisms. The bacteria, Shewanella, are commonly found in water and soil and are of interest because they can convert simple ...

Out-of-body Experience Recreated

Thursday, August 30th, 2007

Experts have found a way to trigger an out-of-body experience in volunteers. The experiments, described in the Science journal, offer a scientific explanation for a phenomenon experienced by one in 10 people. Two teams used virtual reality goggles to con the brain into thinking the body was located elsewhere. The visual ...
