| How tadpoles re-grow their tails: Implications for human healing Posted: 13 Jan 2013 05:11 PM PST Scientists have made a surprising finding after studying how tadpoles re-grow their tails which could have big implications for research into human healing and regeneration.  |
| What did our ancestors look like? Hair and eye color can be determined for ancient human remains Posted: 13 Jan 2013 05:11 PM PST A new method of establishing hair and eye color from modern forensic samples can also be used to identify details from ancient human remains, finds a new study. The HIrisPlex DNA analysis system was able to reconstruct hair and eye color from teeth up to 800 years old, including the Polish General Wladyslaw Sikorski (1881 to 1943) confirming his blue eyes and blond hair.  |
| Foot soldiers of the immune system Posted: 13 Jan 2013 11:49 AM PST Researchers have discovered the molecular blueprint behind the IFIT protein. This key protein enables the human immune system to detect viruses and prevent infection by acting as foot soldiers guarding the body against infection. The findings are a promising step towards developing new drugs for combating a wide range of immune system disorders.  |
| Scientists reassemble the backbone of earliest four-legged animals using synchrotron X-rays Posted: 13 Jan 2013 11:49 AM PST Scientists have been able to reconstruct, for the first time, the intricate three-dimensional structure of the backbone of early tetrapods, the earliest four-legged animals. High-energy X-rays and a new data extraction protocol allowed the researchers to reconstruct the backbones of the 360 million year old fossils in exceptional detail and shed new light on how the first vertebrates moved from water onto land.  |
| Graphene plasmonics beats the drug cheats Posted: 13 Jan 2013 11:49 AM PST Wonder material graphene could help detect the presence of drugs or toxins in the body or dramatically improve airport security, researchers have found.  |
| Genome of diamondback moth provides new clues for sustainable pest management Posted: 13 Jan 2013 11:49 AM PST Chinese scientists have decoded the first genome of diamondback moth, providing new clues for sustainable pest management.  |
| Cancer suppressor gene links metabolism with cellular aging Posted: 13 Jan 2013 11:49 AM PST The tumor suppressor protein p53 is an attractive target for drug developers. But this path has so far proven difficult, as most p53 regulatory proteins operate via protein-protein interactions, which make for poor drug targets, as opposed to ones based on enzymes. Now, researchers have identified a class of p53 target genes and regulatory molecules that represent more promising therapeutic candidates.  |
| Pill-sized device provides rapid, detailed imaging of esophageal lining Posted: 13 Jan 2013 11:49 AM PST Physicians may soon have a new way to screen patients for Barrett's esophagus, a precancerous condition usually caused by chronic exposure to stomach acid. Researchers have developed an imaging system enclosed in a capsule about the size of a multivitamin pill that creates detailed, microscopic images of the esophageal wall.  |
| Gas that triggers ozone destruction revealed Posted: 13 Jan 2013 11:48 AM PST Scientists have made a significant discovery about the cause of the destruction of ozone over oceans.  |
