A new tungsten-based alloy developed at Los Alamos National Laboratory can withstand unprecedented amounts of radiation without damage. Essential for extreme irradiation environments such as the interiors of magnetic fusion reactors, previously explored materials have thus far been hobbled by weakness against fracture, but this new alloy seems to defeat that problem. “This material showed…
For people with multiple sclerosis (MS), drinking around 290 calories per day of soda or other sugar-sweetened beverages, or the equivalent of about two cans of non-diet soda, may be tied to more severe symptoms and a higher level of disability compared to people with MS who seldom consume sugar-sweetened beverages, according to a preliminary…
Although young women strive to be healthy, few perceive themselves as at risk for heart disease and they worry far more about stress and mood disorders than their heart health, according to two preliminary studies presented at the American Heart Association’s Epidemiology and Prevention | Lifestyle and Cardiometabolic Health Scientific Sessions 2019, a premier global…
An international team of researchers from the University of Oxford, the University of Birmingham and Ben-Gurion University of the Negev have found that the way in which people use the internet is closely tied to patterns and rhythms in the natural world. This finding, publishing March 5 in the open-access journal PLOS Biology suggests new…
It’s no secret that our genes are what makes us… us! But genes are often also the basis for debilitating diseases. One of the major clues to understanding any illness is seeing which genes are acting unusually during disease onset. But it’s not often clear if unusual gene activity is unique to the disease at…
Two new studies point to yet more reasons to kick the tobacco habit. In one, researchers found quitting smoking is worth it for people with diabetes despite worries about potential weight gain. In the other, scientists discovered smoking might have a much greater impact on the cognitive function than originally thought. Both studies were presented…
In a recent study, University of Montana researchers explored the ways forest succession and climate variability interacted and influenced fires in Alaska’s boreal forests over the past four centuries — from 1550 to 2015. “We reconstructed fire activity over the last 450 years using lake-sediment records,” said Tyler Hoecker, the study’s lead author. As part…
Scientists are puzzling out how to address the declining numbers of northern spotted owls (NSO) in their Pacific Northwest forest habitat. A new study in the Ecological Society of America’s journal Ecological Applications explores the reasons why spotted owls are losing a foothold in their habitat, forecasts future habitat conditions and species interactions, and suggests…
A second person has experienced sustained remission from HIV-1 after ceasing treatment, reports a paper led by researchers at UCL and Imperial College London. The case report, published in Nature and carried out with partners at the University of Cambridge and the University of Oxford, comes ten years after the first such case, known as…
Faster results. Lower costs. Fewer cells. A new mathematical method developed by researchers at Cincinnati Children’s and New York University may soon make it much easier to conduct more of the complex data analysis needed to drive advances in the exploding field of personalized medicine. Proof-of-principle results for the method are reported this month in…
