| NASA Mars Orbiter examines dramatic new crater Posted: 06 Feb 2014 01:44 PM PST Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as one seen in a NASA image released Feb. 5, 2014. |
| Autism: Birth hormone may control expression of the syndrome in animals Posted: 06 Feb 2014 11:21 AM PST A new article demonstrates that chloride levels are abnormally elevated from birth in the neurons of mice used in an animal model of autism. Researchers show for the first time that oxytocin, the birth hormone, brings about a decrease in chloride level during birth, which controls the expression of the autistic syndrome. |
| Nutritional supplement improves cognitive performance in older adults, study finds Posted: 06 Feb 2014 10:39 AM PST A neuroscientist and gerontologist team up to investigate the effects of a antioxidant-rich nutritional supplement on the mental performance of older adults without impaired memory. An initial clinical trial indicates that the supplement, including blueberries and green tea extracts, improves cognitive processing speeds. |
| Pacific salmon inherit magnetic sense of direction Posted: 06 Feb 2014 10:36 AM PST A team of scientists last year presented evidence of a correlation between the migration patterns of ocean salmon and Earth's magnetic field, suggesting it may help explain how the fish can navigate across thousands of miles of water to find their river of origin. This week, scientists confirmed the connection between salmon and the magnetic field. |
| Scientists reprogram skin cells into insulin-producing pancreas cells Posted: 06 Feb 2014 10:36 AM PST A cure for type 1 diabetes has long eluded even the top experts. Not because they do not know what must be done -- but because the tools did not exist to do it. But now scientists, harnessing the power of regenerative medicine, have developed a technique in animal models that could replenish the very cells destroyed by the disease. |
| False memories: The hidden side of our good memory Posted: 05 Feb 2014 05:00 AM PST Justice blindly trusts human memory. Every year throughout the world hundreds of thousands of court cases are heard based solely on the testimony of somebody who swears that they are reproducing exactly an event that they witnessed in a (more or less) not too distant past. Nevertheless, various recent studies in cognitive neuroscience indicate both the strengths and weaknesses in this ability of recall of the human brain. |
| We recognize less attractive faces best: How attractiveness interferes with recognition of faces Posted: 04 Feb 2014 07:17 AM PST We tend to remember unattractive faces better than attractive ones, according to new research. Psychologists write that attractive faces without particularly remarkable features leave much less distinctive impressions on our memory. |
| Posted: 03 Feb 2014 10:15 AM PST Using radiocarbon dating, archaeologists can pinpoint the moment when domesticated camels arrived in the southern Levant. Their findings further emphasize the disagreements between Biblical texts and verifiable history, and define a turning point in Israel's engagement with the rest of the world. |
