| A new, highly sensitive chemical sensor uses protein nanowires Posted: 13 May 2020 11:34 AM PDT Scientists report that they have developed bioelectronic ammonia gas sensors that are among the most sensitive ever made. It uses electric-charge-conducting protein nanowires derived from the bacterium Geobacter to provide biomaterials for electrical devices. They grow hair-like protein filaments that work as nanoscale ''wires'' to transfer charges for their nourishment and to communicate with other bacteria. |
| Breakthrough study of perplexing stellar pulsations Posted: 13 May 2020 10:55 AM PDT Astronomers have detected elusive pulsation patterns in dozens of young, rapidly rotating stars thanks to data from NASA's Transiting Exoplanet Survey Satellite (TESS). |
| Can't touch this! Video shows blacktip sharks use shallow water to flee huge predators Posted: 13 May 2020 08:14 AM PDT Aerial drone footage provides the first evidence of adult blacktip sharks using shallow waters as a refuge from a huge predator -- the great hammerhead. Before this study, documentation of adult sharks swimming in shallower waters to avoid predation did not exist. Unmanned aerial vehicles enable scientists to unobtrusively observe behaviors in the wild, providing insight into seldom-seen predator-prey interactions. When it comes to sharks, this 'hammerhead' time video proves you 'can't touch this.' |
| Cold War nuke tests changed rainfall Posted: 13 May 2020 08:14 AM PDT Historic records from weather stations show that rainfall patterns in Scotland were affected by charge in the atmosphere released by radiation from nuclear bomb tests carried out in the 1950s and '60s. |
| Posted: 13 May 2020 05:17 AM PDT Earth-based experiments on iron-sulfur alloys thought to comprise the core of Mars reveal details about the planet's seismic properties for the first time. This information will be compared to observations made by Martian space probes in the near future. Whether the results between experiment and observation coincide or not will either confirm existing theories about Mars' composition or call into question the story of its origin. |
| Acute stress may slow down the spread of fears Posted: 12 May 2020 10:45 AM PDT Psychologists find that we are less likely to amplify fears in social exchange if we are stressed. |
| Our ability to focus may falter after eating one meal high in saturated fat Posted: 12 May 2020 10:44 AM PDT Fatty food may feel like a friend during these troubled times, but new research suggests that eating just one meal high in saturated fat can hinder our ability to concentrate -- not great news for people whose diets have gone south while they're working at home during the COVID-19 pandemic. |
