| That giant tarantula is terrifying, but I'll touch it: Expressing your emotions can reduce fear Posted: 04 Sep 2012 04:20 PM PDT Can simply describing your feelings at stressful times make you less afraid and less anxious? A new psychology study suggests that labeling your emotions at the precise moment you are confronting what you fear can indeed have that effect.  |
| 'Benign' malaria key driver of human evolution in Asia-Pacific Posted: 04 Sep 2012 02:09 PM PDT The malaria species rampant in the Asia-Pacific region has been a significant driver of evolution of the human genome, a new study has shown. An international team of researchers has shown that Plasmodium vivax malaria, the most prevalent malaria species in the Asia-Pacific, is a significant cause of genetic evolution that provides protection against malaria.  |
| Watching quantum mechanics in action: Researchers create world record laser pulse Posted: 04 Sep 2012 12:01 PM PDT A research team has created the world's shortest laser pulse and in the process may have given scientists a new tool to watch quantum mechanics in action -- something that has been hidden from view until now.  |
| Posted: 04 Sep 2012 09:11 AM PDT Spinach power has just gotten a big boost. Researchers have combined the photosynthetic protein that converts light into electrochemical energy in spinach with silicon, the material used in solar cells, in a fashion that produces substantially more electrical current than has been reported by previous "biohybrid" solar cells.  |
| For the rooster, size matters: How size of hen's comb is linked to ability to lay more eggs Posted: 04 Sep 2012 07:00 AM PDT A lone rooster sees a lot of all the hens in the flock, but the hen with the largest comb gets a bigger dose of sperm -- and thus more chicks. Researchers in Sweden have now shown how the size of a hen's comb is bound up with the ability to lay more eggs.  |
| Little evidence of health benefits from organic foods, study finds Posted: 03 Sep 2012 07:11 PM PDT Researchers have carried out the most comprehensive meta-analysis to date of existing studies comparing organic and conventional foods. They did not find strong evidence that organic foods are more nutritious or carry fewer health risks than conventional alternatives, though consumption of organic foods can reduce the risk of pesticide exposure.  |
| The eyes have it: Men and women do see things differently, study of brain's visual centers finds Posted: 03 Sep 2012 07:10 PM PDT The way that the visual centers of men and women's brains works is different, finds new research. Men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors.  |
| Less ferocious Tasmanian devils could help save species from extinction Posted: 03 Sep 2012 07:10 PM PDT Evolving to become less aggressive could be key to saving the Tasmanian devil -- famed for its ferocity -- from extinction, research suggests. The species is being wiped out by Devil Facial Tumour Disease (DFTD), a fatal infectious cancer spread by biting. The new study found the less often a devil gets bitten, the more likely it is to become infected with the cancer.  |
