Atom-thick CCD could capture images Posted: 19 Dec 2014 01:06 PM PST An atomically thin material may lead to the thinnest-ever imaging platform. Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for superthin devices.

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.

Europe shows that humans and large predators can share the same landscape Posted: 19 Dec 2014 10:01 AM PST The recovery of large carnivores in Europe is a great success for nature conservation. At one third of mainland Europe, at least one species of large carnivore is present, according to a new article. It is an excellent example that humans and carnivores can share the same landscape, say researchers.

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.

Antibiotic resistance is a gut reaction Posted: 16 Dec 2014 08:30 AM PST Scientists have discovered how certain gut bacteria can protect themselves and others in the gut from antibiotics. The gut is home to hundreds of trillions of bacteria, which have important roles in maintaining our health. But a side effect of taking antibiotics is that these may also kill off some of our beneficial gut bacteria, allowing harmful bacteria to gain a foothold and cause an infection.
