PHILADELPHIA, Aug. 21, 2016 -- Although rechargeable batteries in smartphones, cars and tablets can be charged again and again, they don't last forever. Old batteries often wind up in landfills or incinerators, potentially harming the environment. And valuable materials remain locked inside. Now, a team of researchers is turning to naturally occurring fungi to drive an environmentally friendly recycling process to extract cobalt and lithium from tons of waste batteries.

The researchers will present their work today at the 252nd National Meeting & Exposition of the American Chemical Society (ACS). ACS, the world's largest scientific society, is holding the meeting here through Thursday. It features more than 9,000 presentations on a wide range of science topics.

PHILADELPHIA, Aug. 21, 2016 -- Most people start racking up scars from an early age with scraped knees and elbows. While many of these fade over time, more severe types such as keloids and scars from burns are largely untreatable. These types of scars are associated with permanent functional loss and, in severe cases, carry the stigma of disfigurement. Now scientists are developing new compounds that could stop scars from forming in the first place.

America had an illegal alien problem long before the terrorist attacks of September 11, 2001, but with the border to Mexico so porous, homeland security quickly focused on heightening surveillance - and this racialized Latino immigrants, according to a sociology paper which used media accounts and government reports, often drawn on anecdotes, to make their case.

In history, 941 A.D. was unspectacular. Small local politics happened, a temple was built, Kievian Rus and the Byzantine Empire had another outbreak of hostilities - but in modern times, it has an interesting distinction. It was the year Europe's oldest living inhabitant was born.

SEATTLE -- Youth cyberbullying is dramatically more likely to occur between current or former friends and dating partners than between students who were never friends or in a romantic relationship, suggests a new study that will be presented at the 111th Annual Meeting of the American Sociological Association (ASA).

"A common concern regarding cyberbullying is that strangers can attack someone, but here we see evidence that there are significant risks associated with close connections," said Diane Felmlee, the lead author of the study and a professor of sociology at The Pennsylvania State University. "The large magnitude of the effects of close relationships on the likelihood of cyberbullying, even after controlling for many other factors, was particularly surprising."

SEATTLE -- Death and mourning were largely considered private matters in the 20th century, with the public remembrances common in previous eras replaced by intimate gatherings behind closed doors in funeral parlors and family homes.

But social media is redefining how people grieve, and Twitter in particular -- with its ephemeral mix of rapid-fire broadcast and personal expression -- is widening the conversation around death and mourning, two University of Washington (UW) sociologists say.

G proteins are molecular switches on the insides of cell membranes. They convey important signals to the inner workings of the cells. The associated receptors are targeted by all kinds of medications. Scientists are now shedding light on precisely how the individual amino acids of the G protein move during the switching process. The discovered mechanism signposts new approaches to the design of new active agents.

The majority of smokers who successfully switch to vaping say they have fewer respiratory infections, according to a study led by Queen Mary University of London (QMUL).

The on-line survey of 941 respondents assessed subjective changes in respiratory symptoms in smokers who switched to vaping for at least two months. The results, published in the Journal of Addiction Research & Therapy, show that 66 per cent of respondents reported an improvement in respiratory symptoms, 29 per cent reported no change and 5 per cent reported worsening.

Brivaracetam (trade name: Briviact) has been approved since January 2016 as add-on therapy for adults and adolescents from 16 years of age with epileptic seizures. The German Institute for Quality and Efficiency in Health Care (IQWiG) had already examined the drug in an early benefit assessment published in May. For several reasons, the indirect comparisons presented by the drug manufacturer were unsuitable to assess an added benefit in comparison with the appropriate comparator therapy. Among other things, the manufacturer had not analysed all relevant outcomes. In the commenting procedure, the manufacturer presented a further indirect comparison.

Nivolumab has been approved since April 2016 as a checkpoint inhibitor for the treatment of adults with locally advanced or metastatic nonsquamous non-small-cell lung cancer (NSCLC) who have already undergone chemotherapy. In an early benefit assessment, the German Institute for Quality and Efficiency in Health Care (IQWiG) has now examined whether in these patients this monoclonal antibody offers advantages over the appropriate comparator therapy.

According to the findings, there is an indication of a major added benefit of nivolumab over docetaxel. An added benefit over the appropriate comparator therapy (best supportive care) is not proven in patients for whom treatment with docetaxel or similar drugs is not indicated.
