Of bugs and brains: Striking similarities in brain structures across invertebrates

Posted: 18 Dec 2014 10:19 AM PST

The fundamental structures underlying learning and memory in the brains of invertebrates as different as a fruit fly and an earthworm are remarkably similar, according to neuroscientists. It turns out that the structure and function of brain centers responsible for learning and memory in a wide range of invertebrate species may possibly share the same fundamental characteristics.

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.

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.

550-million-year-old fossils provide new clues about fossil formation

Posted: 18 Dec 2014 09:08 AM PST

A new study is challenging accepted ideas about how ancient soft-bodied organisms become part of the fossil record. Findings suggest that bacteria involved in the decay of those organisms play an active role in how fossils are formed -- often in a matter of just a few tens to hundreds of years. Understanding the relationship between decay and fossilization will inform future study and help researchers interpret fossils in a new way.

Atom-thick CCD could capture images

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.
