Crucial peatlands carbon-sink vulnerable to rising sea levels, research shows

Rising sea-levels linked to global warming could pose a significant threat to the effectiveness of the world's peatland areas as carbon sinks, a new study has shown.

The pioneering new study, carried out by Geographers at the University of Exeter, examined the impact that salt found in sea water has on how successfully peatland ecosystems accumulate carbon from the atmosphere.

Fog, blizzards, gusts of wind - poor weather can often make the operation of rescue helicopters a highly risky business, and sometimes even impossible. A new helmet-mounted display, developed by researchers at the Technical University of Munich (TUM), may in the future be able to help pilots detect hazards at an early stage, even when their visibility is severely impaired: the information required to do this is created in an on-board computer and imported into digital eye glasses. A new study has shown that this augmented reality improves the performance of pilots.

Bottom Line: Women with a history of severe cervical intraepithelial neoplasia, a precancerous condition of the cervix that arises from infection with the human papillomavirus (HPV), had a long-term increased risk of developing anal, vulvar, and vaginal cancer.

Journal in Which the Study was Published: Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Author: Susanne Krüger Kjær, a professor of gynecological cancer epidemiology at The Danish Cancer Society Research Center and Department of Gynecology at the Juliane Marie Centre, Rigshospitalet, Copenhagen University Hospital, Denmark.

Climate has influenced the distribution patterns of Adélie penguins across Antarctica for millions of years.

The geologic record shows that as glaciers expanded and covered Adélie breeding habitats with ice, penguin colonies were abandoned. When the glaciers melted during warming periods, this warming positively affected the Adélie penguins, allowing them to return to their rocky breeding grounds.

But now, University of Delaware scientists and colleagues report that this beneficial warming may have reached its tipping point.

WASHINGTON -- Contrary to the opinions of some courts, it is easier to determine the truthfulness of a woman wearing a headscarf or even a veil that leaves only her eyes exposed than a woman wearing no head covering at all, according to research published by the American Psychological Association.

"The presence of a veil may compel observers to pay attention to more 'diagnostic' cues, such as listening for verbal indicators of deception," said Amy-May Leach, PhD, of the University of Ontario Institute of Technology. The study was published in the APA journal Law and Human Behavior.

Tropical Cyclone 02A made its way west across the Arabian Sea and NASA's Aqua satellite passed over the storm when it was just off the coast of Oman. Infrared data showed the storm was beginning to elongate from wind shear.

Infrared data taken from NASA's Aqua satellite on June 27, 2016 at 2159 UTC (5:59 p.m. EDT) showed cold cloud top temperatures in strong storms just off the coast of Oman. The Atmospheric Infrared Sounder or AIRS instrument flies aboard Aqua. AIRS data was made into a false-colored infrared image at NASA's Jet Propulsion Laboratory in Pasadena, California.

Forget mousetraps -- today's scientists will get the cheese if they manage to build a better battery.

An international team led by Texas A&M University chemist Sarbajit Banerjee is one step closer, thanks to new research published today (June 28) in the journal Nature Communications that has the potential to create more efficient batteries by shedding light on the cause of one of their biggest problems -- a "traffic jam" of ions that slows down their charging and discharging process.

ITHACA, N.Y. - The enzyme sirtuin 6, or SIRT6, serves many key biological functions in regulating genome stability, DNA repair, metabolism and longevity, but how its multiple enzyme activities relate to its various functions is poorly understood.

A team of Cornell University researchers, led by Hening Lin, professor of chemistry and chemical biology, has devised a method for isolating one specific enzyme activity to determine its contribution and lead to better overall understanding of SIRT6.

Their work, "Identifying the functional contribution of the defatty-acylase activity of SIRT6," was published June 20 in Nature Chemical Biology. Xiaoyu Zhang, graduate student in chemistry and chemical biology and a member of the Lin Group, was lead author.

CHAPEL HILL - Across North Carolina, the risk of death from the most common form of acute leukemia in adults was significantly higher in three regions, researchers from the University of North Carolina Lineberger Comprehensive Cancer Center found.

In a retrospective study published in the journal Cancer, researchers report that adults treated with chemotherapy in the hospital for acute myeloid leukemia, or AML, between 2003 to 2009 had a statistically significant higher risk of death if they lived in northeastern North Carolina from Wilson to Roanoke Rapids, in a region around Greenville, and a region around Wake County, including Durham County. Those differences remained even after researchers controlled for other factors that might help drive the increases.

BOSTON (June 28, 2016)--Researchers at Tufts University School of Dental Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts, led by Jonathan Garlick, have established for the first time that skin cells from diabetic foot ulcers can be reprogrammed to acquire properties of embryonic-like cells. These induced pluripotent stem cells might someday be used to treat chronic wounds. The study is published online in advance of print in Cellular Reprogramming.

A second study from the research team published in Wound Repair and Regeneration found that a protein called fibronectin is linked to a break-down in the wound-healing process in cells from diabetic foot ulcers.
