| Mice show innate ability to vocalize: Deaf or not, courting male mice make same sounds Posted: 26 Mar 2013 04:41 PM PDT While humans and birds must learn to vocalize, a neurophysiologist has found that deaf male mice will vocalize to females the same way as hearing mice. The finding points the way to a more finely focused, genetic tool for teasing out the mysteries of speech and its disorders. |
| Researchers discover how model organism Tetrahymena plays roulette with seven sexes Posted: 26 Mar 2013 04:41 PM PDT It's been more than fifty years since scientists discovered that the single-celled organism Tetrahymena thermophila has seven sexes. But in all that time, they've never known how each cell's sex, or "mating type," is determined; now they do. |
| Saliva testing predicts aggression in boys Posted: 26 Mar 2013 01:21 PM PDT A new study indicates that a simple saliva test could be an effective tool in predicting violent behavior. |
| Trees used to create recyclable, efficient solar cell Posted: 26 Mar 2013 08:19 AM PDT Researchers have developed efficient solar cells using natural substrates derived from plants such as trees. Just as importantly, by fabricating them on cellulose nanocrystal (CNC) substrates, the solar cells can be quickly recycled in water at the end of their lifecycle. |
| Posted: 26 Mar 2013 07:16 AM PDT Humans don't "own" their own genes, the cellular chemicals that define who they are and what diseases they might be at risk for. Through more than 40,000 patents on DNA molecules, companies have essentially claimed the entire human genome for profit, report two researchers who analyzed the patents on human DNA. Their study raises an alarm about the loss of individual "genomic liberty." |
| Uncovering Africa's oldest known penguins Posted: 26 Mar 2013 07:16 AM PDT Africa isn't the kind of place you might expect to find penguins. But one species lives in Africa today, and new fossils confirm that as many as four penguin species coexisted on the continent in the past. Exactly why African penguin diversity plummeted is still a mystery, but changing sea levels may be to blame. The fossils represent the oldest evidence of penguins in Africa, predating previously described fossils by 5 to 7 million years. |
| Scientists form new nerve cells -- directly in the brain Posted: 26 Mar 2013 07:08 AM PDT The field of cell therapy, which aims to form new cells in the body in order to cure disease, has taken another important step in the development towards new treatments. A new report shows that it is possible to re-program other cells to become nerve cells, directly in the brain. |
| 'Metascreen' forms ultra-thin invisibility cloak Posted: 25 Mar 2013 05:25 PM PDT Up until now, the invisibility cloaks put forward by scientists have been fairly bulky contraptions -- an obvious flaw for those interested in Harry Potter-style applications. |
