Adolescents with severe obesity who had bariatric surgery showed significant improvements in cardiovascular disease risk factors, according to the most recent "Teen Longitudinal Assessment of Bariatric Surgery" (Teen-LABS) study, published online today by Pediatrics. Prior to bariatric surgery, 33 percent of the study participants had three or more defined cardiovascular disease risk factors.

Philadelphia, January 8, 2018 - Dietary self-monitoring is a key component of successful behavioral weight loss interventions and is essential for facilitating other behavior change techniques (eg, setting goals, providing behavioral feedback). Few studies, however, have examined weekly and seasonal patterns of dietary self-monitoring, particularly when using a smartphone application (app).

A powerful antiviral protein may act as a checkpoint for keeping or ending a pregnancy.

When exposed to Zika virus before birth, mouse fetuses with the protein commit cell suicide, while fetuses without it continued to develop. The result, published January 5 in Science Immunology, suggests that the protein, a receptor involved in immune cell signaling, plays a role in spontaneous abortions and other human pregnancy complications.

MISSOULA - University of Montana researchers have made another discovery at the cellular level to help understand the basic processes of all life on our planet - this time within the unusual bacteria that has lived inside cicada insects since dinosaurs roamed Earth.

During the past 70 million years, the bacteria underwent extreme adaptations to live within the insects' bodies, losing between an estimated 95 to 97 percent of their genes and resulting in some of the smallest genomes known to any organisms. In the process, they lost the ability to live anywhere outside of cicadas.

An old drug supercharged by University of Queensland researchers has emerged as a new antibiotic that could destroy some of the world's most dangerous superbugs.

The supercharge technique , led by Dr Mark Blaskovich and Professor Matt Cooper from UQ's Institute for Molecular Bioscience (IMB), potentially could revitalise other antibiotics.

Antibiotic-resistant bacteria - superbugs - cause 700,000 deaths worldwide each year, and a UK government review has predicted this could rise to 10 million by 2050.

Engineers at Rice University's Nanotechnology Enabled Water Treatment (NEWT) Center have found a catalyst that cleans toxic nitrates from drinking water by converting them into air and water.

The research is available online in the American Chemical Society journal ACS Catalysis.

Boulder, Colo., USA: In Oklahoma, reducing the amount of saltwater (highly brackish water produced during oil and gas recovery) pumped into the ground seems to be decreasing the number of small fluid-triggered earthquakes. But a new study shows why it wasn't enough to ease bigger earthquakes. The study, led by Ryan M. Pollyea of Virginia Tech in Blacksburg, Virginia, was published online ahead of print in Geology this week.

Recent advances in brain imaging have enabled scientists to show for the first time that a key protein which causes nerve cell death spreads throughout the brain in Alzheimer's disease - and hence that blocking its spread may prevent the disease from taking hold.

In order to survive in a changing environment, animals and humans must integrate sensory information and their experience to select the most appropriate behavior for a given situation. This process is ultimately constrained by the range of possible motor outputs they can produce.

ATLANTA -January 4, 2018-The cancer death rate dropped 1.7% from 2014 to 2015, continuing a drop that began in 1991 and has reached 26%, resulting in nearly 2.4 million fewer cancer deaths during that time.

The data is reported in Cancer Statistics 2018, the American Cancer Society's comprehensive annual report on cancer incidence, mortality, and survival. It is published in CA: A Cancer Journal for Clinicians and is accompanied by its consumer version: Cancer Facts and Figures 2018.
