| Ants 'screen' for beneficial bacteria to assist them Posted: 22 Aug 2012 07:25 PM PDT Having healthy gut bacteria could have as much to do with a strategy that insurance companies use to uncover risk as with eating the right foods - according to researchers.  |
| Transparent, thin and tough: Why don't insect wings break? Posted: 22 Aug 2012 03:12 PM PDT Researchers have shown that the wings of insects are not as fragile as they might look. The characteristic network of veins found in the wings of grasshoppers helps to capture cracks, similar to watertight compartments in a ship.  |
| Roots of human self-awareness: New study points to a complex, diffuse patchwork of brain pathways Posted: 22 Aug 2012 03:12 PM PDT A research team has upended current thinking about areas in the human brain responsible for self-awareness. Using a rare patient with damage to areas considered vital to be self-aware, the team learned the patient was not only self-aware, but capable of introspection and self-insight. The researchers propose that self-awareness is a product of a diffuse patchwork of pathways in the brain rather than confined to specific areas.  |
| Intense prep for law school admission test alters brain structure Posted: 22 Aug 2012 09:52 AM PDT Intense prep courses for the Law School Admission Test are popular for good reason: They can improve scores significantly. Now neuroscientists have revealed the underlying impact of such preparation: The brain's neural connections change measurably, suggesting a bolstering of physical interconnections among reasoning areas of the brain. Diffusion tensor imaging scans of students before and after an intense three-month prep course showed increased connections between verbal and spatial reasoning areas of the brain.  |
| Ancient fossils reveal how the mollusc got its teeth Posted: 22 Aug 2012 09:52 AM PDT The radula sounds like something from a horror movie -- a conveyor belt lined with hundreds of rows of interlocking teeth. In fact, radulas are found in the mouths of most molluscs, from the giant squid to the garden snail. Now, a "prototype" radula found in 500-million-year-old fossils shows that the earliest radula was not a flesh-rasping terror, but a tool for humbly scooping food from the muddy sea floor.  |
| Good news for banana lovers: Help may be on the way to slow that rapid over-ripening Posted: 22 Aug 2012 07:08 AM PDT A solution finally may be at hand for the number one consumer gripe about bananas: their tendency to ripen, soften and rot into an unappetizing mush, seemingly in the blink of an eye. Scientists have described efforts to develop a spray-on coating that would delay the ripening of bananas.  |
| Are the eyes the key to a new test for Alzheimer's disease? Posted: 22 Aug 2012 06:17 AM PDT A simple eye tracking test could hold the key to earlier Alzheimer's diagnosis, according to new research.  |
| Male mice exposed to chronic social stress have anxious female offspring Posted: 22 Aug 2012 06:16 AM PDT A study in mice suggests that a woman's risk of anxiety and dysfunctional social behavior may depend on the experiences of her parents, particularly fathers, when they were young.  |
