(University of Central Florida) Despite widespread infection, some frog populations are surviving a deadly disease that is the equivalent of mankind's Ebola virus. The reason -- genetic diversity. That's the finding of a new study published this week in the journal Immunogenetics. Anna Savage, an assistant professor of biology at the University of Central Florida, is the lead author of the study.

(University of Minnesota) Scientists from 52 countries will be providing hands-on help in Puerto Rico to restore marine and coastal resources damaged during hurricane Maria in 2017 in connection with the annual meeting of the Association for the Sciences of Limnology and Oceanography February 23 to March 2, 2019. The Puerto Rico and Minnesota Sea Grant programs are working together with Puerto Rico-based members of the meeting committee to offer educational and volunteer opportunities focused on environmental restoration.

(University of Guelph) Researchers found that if a squirrel inherits territory from a male rather than a female, it will have about 1,300 more cones in its midden. This stored energy will keep the squirrel alive an extra 17 days. For females it means she will enough food to breed earlier, resulting in her offspring leaving the nest earlier. This shows how the behavior of a complete stranger can impact the genetic contribution of another.

(Massachusetts Institute of Technology) MIT scientists have devised a reliable way to determine when certain groups of bacteria appeared in the evolutionary record. The technique could be used to identify when significant changes occurred in the evolution of bacteria, and to reveal details about the primitive environments that drove such changes in the first place.

(University at Buffalo) As the Arctic warms, it's predicted to get wetter. But why? A new study looks to history for answers, examining what happened in the region during a period of warming some 8,000 years ago. The research finds evidence that in this ancient time, western Greenland became more humid, a trend often linked to increased precipitation. The study further shows that two different climactic processes may have contributed to this elevated humidity.

(NASA/Goddard Space Flight Center) With each of its 10,000 pulses per second, the laser instrument aboard NASA's ICESat-2 is sending 300 trillion green photons of light to the ground and detecting the few that return: the method it uses to measure Earth's changing ice. By the morning of Oct. 3, ICESat-2 returned its first height measurements across the Antarctic ice sheet.

(Oregon Health & Science University) New research for the first time reveals the three-dimensional structure of a membrane channel that's critical in controlling blood pressure. The findings, published today in the open-access journal eLife, represent the first time the human epithelial sodium channel has been shown so precisely since it was first isolated and described through expression cloning more than two decades ago.

(University of Colorado at Boulder) In the last few years, the Vavilov Ice Cap in the Russian High Arctic has dramatically accelerated, sliding as much as 82 feet a day in 2015, according to a new multi-national, multi-institute study led by CIRES Fellow Mike Willis, an assistant professor of Geology at CU Boulder. That dwarfs the ice's previous average speed of about 2 inches per day and has challenged scientists' assumptions about the stability of the cold ice caps dotting Earth's high latitudes.

(Ruhr-University Bochum) Researchers have developed a new mechanism to protect enzymes from oxygen as biocatalysts in fuel cells. The enzymes, known as hydrogenases, are just as efficient as precious metal catalysts, but unstable when they come into contact with oxygen. They are therefore not yet suitable for technological applications. The new protective mechanism is based on oxygen-consuming enzymes that draw their energy from sugar.
