Lost memories might be able to be restored Posted: 20 Dec 2014 07:41 AM PST New research indicates that lost memories can be restored. The findings offer some hope for patients in the early stages of Alzheimer's disease.

New species found in the deepest trench on Earth Posted: 20 Dec 2014 01:05 AM PST Researchers have returned from the first detailed study of the Mariana Trench aboard Schmidt Ocean Institute's research vessel Falkor. The expedition set many new records, including the deepest rock samples ever collected and the discovery of new fish species at the greatest depths ever recorded.

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.

Reducing emergency surgery cuts health care costs Posted: 19 Dec 2014 01:05 PM PST Researchers have determined the hospital costs and risk of death for emergency surgery and compared it to the same operation when performed in a planned, elective manner for three common surgical procedures: abdominal aortic aneurysm repair, coronary artery bypass graft and colon resection. The research indicates that reducing emergency surgery for three common procedures by 10 percent could cut $1 billion in health care costs over 10 years.

Family criticizing your weight? You might add more pounds Posted: 19 Dec 2014 01:05 PM PST Women whose loved ones are critical of their weight tend to put on even more pounds, says a new study on the way people's comments affect our health. "When we feel bad about our bodies, we often turn to loved ones -- families, friends and romantic partners -- for support and advice. How they respond can have a bigger effect than we might think," said one author.

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.

Yellowstone's thermal springs: Their colors unveiled Posted: 19 Dec 2014 10:01 AM PST Researchers have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone National Park's hot springs and can visually recreate how they appeared years ago, before decades of tourists contaminated the pools with make-a-wish coins and other detritus.
