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…
