| Scientists develop biological computer to encrypt and decipher images Posted: 07 Feb 2012 05:28 PM PST Scientists have developed a "biological computer" made entirely from biomolecules that is capable of deciphering images encrypted on DNA chips.  |
| Discovery uses 'fracture putty' to repair broken bone in days Posted: 07 Feb 2012 04:34 PM PST Broken bones in humans and animals are painful and often take months to heal. New research shows promise to shorten healing time significantly and revolutionize the course of fracture treatment.  |
| Ancient seagrass holds secrets of the oldest living organism on Earth Posted: 07 Feb 2012 12:25 PM PST It's big, it's old and it lives under the sea -- and now an international research collaboration has confirmed that an ancient seagrass holds the secrets of the oldest living organism on Earth. Ancient giant Posidonia oceanica reproduces asexually, generating clones of itself. A single organism -- which has been found to span up to 15 kilometers in width and reach more than 6,000 metric tonnes in mass -- may well be more than 100,000 years old.  |
| Mars Express radar yields strong evidence of ocean that once covered part of Red Planet Posted: 07 Feb 2012 12:18 PM PST ESA's Mars Express has returned strong evidence for an ocean once covering part of Mars. Using radar, it has detected sediments reminiscent of an ocean floor within the boundaries of previously identified, ancient shorelines on Mars.  |
| Entire genome of extinct human decoded from fossil Posted: 07 Feb 2012 10:36 AM PST Scientists have completed the genome sequence of a Denisovan, a representative of an Asian group of extinct humans related to Neanderthals.  |
| Why bad immunity genes survive: Study implicates arms race between genes and germs Posted: 07 Feb 2012 09:18 AM PST Biologists have found new evidence for why mice, people and other vertebrate animals carry thousands of varieties of genes to make immune-system proteins named MHCs -- even though some of those genes make us sick.  |
| Neanderthal demise due to many influences, including cultural changes Posted: 07 Feb 2012 07:01 AM PST Although many anthropologists believe that modern humans ancestors "wiped out" Neanderthals, it's more likely that Neanderthals were integrated into the human gene pool thousands of years ago during the Upper Pleistocene era as cultural and climatic forces brought the two groups together.  |
| Exercise triggers stem cells in muscle Posted: 06 Feb 2012 11:39 AM PST Researchers have determined that an adult stem cell present in muscle is responsive to exercise, a discovery that may provide a link between exercise and muscle health. The findings could lead to new therapeutic techniques using these cells to rehabilitate injured muscle and prevent or restore muscle loss with age.  |
| Sharp images from the living mouse brain Posted: 06 Feb 2012 09:24 AM PST Scientists have for the first time made finest details of nerve cells in the brain of a living mouse visible.  |
| Materials for first optical fibers with high-speed electronic function are developed Posted: 05 Feb 2012 01:37 PM PST For the first time, researchers have developed crystalline materials that allow an optical fiber to have integrated, high-speed electronic functions. The potential applications of such optical fibers include improved telecommunications and other hybrid optical and electronic technologies, improved laser technology, and more-accurate remote-sensing devices.  |
| Researchers rewrite textbook on location of brain's speech processing center Posted: 30 Jan 2012 02:19 PM PST Scientists have long believed that human speech is processed towards the back of the brain's cerebral cortex, behind auditory cortex where all sounds are received -- a place famously known as Wernicke's area. But, now, research that analyzed more than 100 imaging studies concludes that Wernicke's area is in the wrong location. The site newly identified is miles away in terms of brain architecture and function.  |
