| Intelligent onboard transportation systems to prevent car crashes? Posted: 14 Jun 2011 05:39 PM PDT Since 2000, there have been 110 million car accidents in the United States, more than 443,000 of which have been fatal -- an average of 110 fatalities per day. These statistics make traffic accidents one of the leading causes of death in this country, as well as worldwide. More progress must be made to achieve the long-term goal of "intelligent transportation": cars that can "see" and communicate with other vehicles on the road, making them able to prevent crashes virtually 100 percent of the time.  |

| Out of reach? Rural elders have highest rates of obesity, diabetes, heart disease Posted: 14 Jun 2011 12:45 PM PDT Despite living in the countryside where open space is plentiful and there is often significant agricultural production, California's more than half a million rural elders are far more likely to be overweight or obese, physically inactive and food insecure than their suburban counterparts, according to a new study. All three conditions are risk factors for heart disease, diabetes and repeated falls -- conditions also more prevalent among rural elders.  |
| Posted: 14 Jun 2011 10:19 AM PDT Scientists have long known that fear and highly emotional experiences lead to incredibly strong memories. A new study describes one way by which emotions can affect memory: The brain's emotional center, the amygdala, induces the hippocampus, a relay hub for memory, to generate new neurons. In a fearful situation, these newborn neurons are activated by the amygdala, providing a "blank slate" to strongly imprint the new fearful memory.  |
| Stress may lead to better bird parenting Posted: 14 Jun 2011 10:19 AM PDT Birds with high levels of stress hormones have the highest mating success and offer better parental care to their brood, according to new biology research.  |
| Surprising connection between two types of perception Posted: 14 Jun 2011 08:56 AM PDT The brain is constantly changing as it perceives the outside world, processing and learning about everything it encounters.  |
| Why hair turns gray: Communication between hair follicles and melanocyte stem cells key to mystery Posted: 14 Jun 2011 08:50 AM PDT A new study has shown that, for the first time, Wnt signaling, already known to control many biological processes, between hair follicles and melanocyte stem cells can dictate hair pigmentation.  |
| College students sleep longer but drink more and get lower grades when classes start later Posted: 14 Jun 2011 07:11 AM PDT Later class start times were associated with a delayed sleep schedule, which led to poorer sleep, more daytime sleepiness, and a lower grade-point average. Students with later class start times also consumed more alcohol and reported more binge drinking. Students who were "night owls" with a natural preference to stay up later were more likely than "morning types" to have a delayed sleep schedule and to consume more alcohol. The study involved 253 college students.  |
| What gamers want: Researchers develop tool to predict player behavior Posted: 14 Jun 2011 07:05 AM PDT Researchers have developed a new method that can accurately predict the behavior of players in online role-playing games. The tool could be used by the game industry to develop new game content, or to help steer players to the parts of a game they will enjoy most.  |
