An international research team led by microbiologists Marc Mussmann and Alexander Loy at the University of Vienna has uncovered a completely new type of microbial metabolism. The newly identified microorganisms, known as MISO bacteria, are able to “breathe” iron minerals by oxidizing toxic sulfide. The scientists discovered that the reaction between hydrogen sulfide — a…

Scientists have devised a new method for mapping the spottiness of distant stars by using observations from NASA missions of orbiting planets crossing their stars’ faces. The model builds on a technique researchers have used for decades to study star spots. By improving astronomers’ understanding of spotty stars, the new model — called StarryStarryProcess —…

Researchers test a chest compression machine on a dummy in an aeroplane CNES Microgravity makes it tricky to do simple tasks like eating, using the toilet and showering, so it is no wonder that performing CPR on someone whose heart stops beating in space is an extremely demanding procedure. But a mechanical device could do…
