| Acute stress primes brain for better cognitive and mental performance Posted: 16 Apr 2013 05:45 PM PDT Chronic stress is known to cause major health problems, yet acute stress can be good for you. A new study shows why. Stress generates new nerve cells in the brain that, two weeks later, help you learn better. Thus, unlike chronic stress, acute stress primes the brain for improved cognitive and mental performance. |
| Memory, the adolescent brain and lying: The limits of neuroscientific evidence in the law Posted: 16 Apr 2013 03:00 PM PDT Brain scans are increasingly able to reveal whether you believe you remember some person or event in your life. In a new study, researchers used fMRI brain scans to detect whether a person recognized scenes from their own lives, as captured in some 45,000 images by digital cameras. The study is seeking to test the capabilities and limits of brain-based technology for detecting memories, a technique being considered for use in legal settings. |
| Posted: 16 Apr 2013 02:16 PM PDT "Survival of the fittest" originally referred to natural selection in biological systems, but new research shows that this evolutionary theory also applies to technological systems. |
| Love at first sniff: Male moths go by first impressions Posted: 16 Apr 2013 09:17 AM PDT Entomologists now have an explanation for why we see so many hybrid moths in nature. The team closely examined the behavior and the olfactory circuitry of male moths and found an answer in female-produced pheromones. |
| Posted: 16 Apr 2013 08:43 AM PDT A parasitic worm may hold the answer to keeping skin grafts firmly in place over wounds. |
| Powerpot turns heat and water into electricity Posted: 16 Apr 2013 08:41 AM PDT Students have invented a portable cook pot that doubles as a thermoelectric generator, and are now marketing it. |
| Paper-thin skin patch collects vitals: E-health made easier and more comfortable Posted: 16 Apr 2013 07:22 AM PDT The future of health care could be found in a tiny, paper-thin skin patch that collects vital information. The Bio-patch sensor is inexpensive, versatile and, best of all, comfortable to wear. |
| Scientists transform cellulose into starch: Potential food source derived from non-food plants Posted: 16 Apr 2013 05:53 AM PDT A team of researchers has succeeded in transforming cellulose into starch, a process that has the potential to provide a previously untapped nutrient source from plants not traditionally though of as food crops. |
