Major ocean current is widening as climate warms

A new study found that the Indian Ocean's Agulhas Current is getting wider rather than strengthening. The findings, which have important implications for global climate change, suggest that intensifying winds in the region may be increasing the turbulence of the current, rather than increasing its flow rate.

Leg movement restored in primates using wireless neural interface

An international team of scientists has used a wireless "brain-spinal interface" to bypass spinal cord injuries in a pair of rhesus macaques, restoring intentional walking movement to a temporarily paralyzed leg. The researchers say this is the first time a neural prosthetic has been used to restore walking movement directly to the legs of nonhuman primates.

Major advance in solar cells made from cheap, easy-to-use perovskite

Physicists have boosted the efficiency of material that holds promise as base for next-generation solar cells. Perovskite solar cells are made of a mix of organic molecules and inorganic elements that together capture light and convert it into electricity, just like today's more common silicon-based solar cells. Perovskite photovoltaic devices, however, can be made more easily and cheaply than silicon and on a flexible rather than rigid substrate.

Greenland fossils reveal global ecosystem recovery after mass extinction

A new study shows how higher latitude ecosystems recovered after the World's most cataclysmic extinction event 252 million years ago.

Evolution purged many Neanderthal genes from human genome

Larger populations allowed humans to shed weakly deleterious gene variants that were widespread in Neanderthals, new research indicates.

Twenty percent of children with Celiac disease do not heal on a gluten-free diet

Even after a year on a gluten-free diet, nearly 20 percent of children with celiac disease continue to have intestinal abnormalities (enteropathy) on repeat biopsies, reports a study.

Early study finds antibody that ‘neutralizes’ Zika virus

Researchers have isolated a human monoclonal antibody that in a mouse model "markedly reduced" infection by the Zika virus, report scientists. Zika is believed to cause microcephaly, unusually small heads, and other congenital malformations in children born to infected women.

New coral research exposes genomic underpinnings of adaptation

Scientists have observed for the first time that separate populations of the same species -- in this case, coral -- can diverge in their capacity to regulate genes when adapting to their local environment. The research reveals a new way for populations to adapt that may help predict how they will fare under climate change.

Gut microbes linked to immunotherapy response in melanoma patients

Patients with malignant melanoma - whose disease has spread - are more likely to respond to immunotherapy treatment if they had greater diversity in their gut bacteria, according to new research.
