source: Phys.org In the eROSITA all-sky survey, scientists at the Max Planck Institute for Extraterrestrial Physics (MPE) have found an interesting repeating event. In an otherwise quiescent galaxy, an X-ray flare repeats every 220 days, indicating that a star orbiting the central black hole “feeds” the gravity monster on subsequent orbits. Such events could be effective tools to explore the accretion process and the gravity field around supermassive black holes in other galaxies.

source: Phys.org In the 1950s, the geneticist J.B.S. Haldane attributed the maintenance or persistence of the mutation responsible for anomalies in red blood cells commonly observed in Africa to the protection these anomalies provided against malaria, an endemic infection that claims millions of lives. This theory suggested that pathogens are among the strongest selective pressures faced by humans. Several population genetics studies subsequently confirmed the theory. Read Full Article Here

source: Phys.org Dogs walked every day by their owners are less aggressive. Dogs owned by women bark less at strangers. Heavier dogs tend to be less disobedient than lighter pets. Pugs, Bulldogs, Shih Tzus and other short-snouted breeds may be more badly behaved than medium- and long-snouted dogs, such as Golden Retrievers or the caramel-colored mixed-breed dogs popular in Brazil.

source: Phys.org Enzymes have the potential to transform the chemical industry by providing green alternatives to a slew of processes. These proteins act as biological catalysts, and with the help of molecular engineering, they can make naturally occurring reactions shift into turbo mode. Tailor-made enzymes could, for example, lead to nonpolluting drug manufacture; they could also safely break down pollutants, sewage and agricultural waste, and then turn them into biofuel or animal feed.
