Lost memories might be able to be restored, suggests research into marine snail Posted: 20 Dec 2014 07:41 AM PST New research indicates that lost memories can be restored, according to new research into a type of marine snail called Aplysia. The findings offer some hope for patients in the early stages of Alzheimer's disease.

First direct evidence that a mysterious phase of matter competes with high-temperature superconductivity Posted: 20 Dec 2014 07:41 AM PST Scientists have found the first direct evidence that a mysterious phase of matter known as the "pseudogap" competes with high-temperature superconductivity, robbing it of electrons that otherwise might pair up to carry current through a material with 100 percent efficiency.

Early exposure to antidepressants affects adult anxiety, serotonin transmission Posted: 19 Dec 2014 01:06 PM PST Early developmental exposure to two different antidepressants, Prozac and Lexapro, has been studied by researchers in a mouse model that mimics human third trimester medication exposure. They found that, although these serotonin-selective reuptake inhibiting antidepressants were thought to work the same way, they did not produce the same long-term changes in anxiety behavior in the adult mice. About 15 percent of women in the United States suffer from anxiety disorders and depression during their pregnancies, and many are prescribed antidepressants.

Neuroscientists identify brain mechanisms that predict generosity in children Posted: 19 Dec 2014 07:39 AM PST Developmental neuroscientists have found specific brain markers that predict generosity in children. Those neural markers appear to be linked to both social and moral evaluation processes. Although young children are natural helpers, their perspective on sharing resources tends to be selfish.

NASA's Kepler reborn, makes first exoplanet find of new mission Posted: 18 Dec 2014 04:44 PM PST NASA's planet-hunting Kepler spacecraft makes a comeback with the discovery of the first exoplanet found using its new mission -- K2. The discovery was made when astronomers and engineers devised an ingenious way to repurpose Kepler for the K2 mission and continue its search of the cosmos for other worlds.

'Tipping points' for sea level rise-related flooding determined Posted: 18 Dec 2014 12:45 PM PST By 2050, a majority of US coastal areas are likely to be threatened by 30 or more days of flooding each year due to dramatically accelerating impacts from sea level rise, according to a new study.

New, tighter timeline confirms ancient volcanism aligned with dinosaurs' extinction Posted: 18 Dec 2014 12:45 PM PST A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago played a role in the extinction event that claimed Earth's non-avian dinosaurs, and challenges the dominant theory that a meteorite impact was the sole cause of the extinction.

Ancient, hydrogen-rich waters deep underground around the world: Waters could support isolated life Posted: 17 Dec 2014 11:11 AM PST A team of scientists has mapped the location of hydrogen-rich waters found trapped kilometers beneath Earth's surface in rock fractures in Canada, South Africa and Scandinavia. Common in Precambrian Shield rocks -- the oldest rocks on Earth -- the ancient waters have a chemistry similar to that found near deep sea vents, suggesting these waters can support microbes living in isolation from the surface.

Personality outsmarts intelligence at school: Conscientiousness and openness key to learning Posted: 17 Dec 2014 06:08 AM PST Recent research has found that personality is more important than intelligence when it comes to success in education and this needs to take this into account when guiding students and teachers. Furthermore these personality traits for academic success can be developed.

Catnip Repels Mosquitoes More Effectively Than DEET Posted: 28 Aug 2001 04:56 AM PDT Researchers report that nepetalactone, the essential oil in catnip that gives the plant its characteristic odor, is about ten times more effective at repelling mosquitoes than DEET — the compound used in most commercial insect repellents.
