Study questions 21-day quarantine period for Ebola

Posted: 15 Oct 2014 08:23 AM PDT

One of the tenets for minimizing the risk of spreading Ebola Virus has been a 21-day quarantine period for individuals who might have been exposed to the virus. But a new study suggests that 21 days might not be enough to completely prevent spread of the virus. Experts say there could be up to a 12 percent chance that someone could be infected even after the 21-day quarantine.

Electric vehicle technology packs more punch in smaller package

Using 3-D printing and novel semiconductors, researchers have created a power inverter that could make electric vehicles lighter, more powerful and more efficient.

Nanoparticles can act like liquid on the outside, crystal on the inside

Posted: 12 Oct 2014 10:49 AM PDT

A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal configuration.

Leaky, star-forming galaxies leads to better understand the universe

Focusing on large, star-forming galaxies, researchers were able to measure radiation leaks in an effort to better understand how the universe evolved as the first stars were formed.

Urine of tiny migrating marine animals affects ocean chemistry

Tiny animals migrating from the ocean's surface to the sunlit depths release ammonia, the equivalent of our urine, that plays a significant role in marine chemistry, particularly in low-oxygen zones.

Snakes and snake-like robots show how sidewinders conquer sandy slopes

Posted: 09 Oct 2014 11:14 AM PDT

The amazing ability of sidewinder snakes to quickly climb sandy slopes was once something biologists only vaguely understood and roboticists only dreamed of replicating. By studying the snakes in a unique bed of inclined sand and using a snake-like robot to test ideas spawned by observing the real animals, both biologists and roboticists have now gained long-sought insights.

Multiple neurodevelopmental disorders have a common molecular cause

Posted: 09 Oct 2014 09:55 AM PDT

Neurodevelopmental disorders such as Down syndrome and autism-spectrum disorder can have profound, lifelong effects on learning and memory, but relatively little is known about the molecular pathways affected by these diseases. A study shows that neurodevelopmental disorders caused by distinct genetic mutations produce similar molecular effects in cells, suggesting that a one-size-fits-all therapeutic approach could be effective for conditions ranging from seizures to attention-deficit hyperactivity disorder.

Price gap between more and less healthy foods grows

Posted: 08 Oct 2014 11:11 AM PDT

Novel use of UK national data finds a growing gap between the prices of more and less healthy foods between 2002 and 2012. Healthy foods in 2012 are three times more expensive per calorie than less healthy foods.
