Modern beer yeast emerged from mix of European grape wine, Asian rice wine yeast — ScienceDaily

For thousands of years brewers made beer using specialized strains of the budding yeast Saccharomyces cerevisiae. The historical origins of brewer’s yeast are not well understood, however, as brewing predates the discovery of microbes. A new study publishing March 5 in the open-access journal PLOS Biology, led by Justin Fay at the University of Rochester,…

First experimental evaluation of pharmaceutical industry-led access program — ScienceDaily

Study of Novartis Access program in Kenya demonstrates it is possible to evaluate major pharmaceutical companies’ access programs using robust, ‘gold standard’ methods. A new study led by Boston University School of Public Health (BUSPH) researchers is the first to use a randomized trial design to generate rigorous evidence on the impact of a pharmaceutical…

Tungsten blend resists fractures, could be valuable for magnetic fusion facilities — ScienceDaily

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…

Soda, sugar-sweetened beverages linked to more severe symptoms for people with multiple sclerosis — ScienceDaily

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…

More immediate concerns beat heart health in the priorities and behaviors of young women — ScienceDaily

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…

Gaining a little weight after quitting tobacco is offset by the benefits for people with diabetes — ScienceDaily

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…
