We think of sharks as solitary creatures. Lurking silently beneath the waves, each single toothy predator operating alone, coming together only temporarily as feasting or mating dictates. We may, however, be totally wrong. According to new research, sharks could be forming large social groups from which smaller numbers break off to forage, and then return

Earthquakes come and go, often leaving a trail of devastation in their wake. What they don’t usually do, thankfully, is turn around immediately and come back for another pass. Except… it looks like they can, in exceedingly rare circumstances. In a new study, scientists have found evidence of an unusual and virtually unprecedented ‘boomerang’ earthquake

NASA’s Perseverance Mars rover launched from Cape Canaveral, Florida, on 30 July, carrying a host of cutting-edge technology including high-definition video equipment and the first interplanetary helicopter. Many of the tools are designed as experimental steps toward human exploration of the red planet. Crucially, Perseverance is equipped with a device called the Mars Oxygen In-Situ Resource Utilization Experiment, or

After a two-month gap, SpaceX has resumed launching batches of dozens of satellites in its gambit to blanket Earth with high-speed internet access. The satellites are a new “VisorSat” variety to make them less shiny to the ground and especially to astronomers’ telescopes. But researchers say the spacecraft’s experimental new feature, while helpful, won’t fully

As if spiderwebs weren’t already icky enough, some spiders have gone and made them poisonous as well, a new study reveals. The unique properties of spiderwebs have long fascinated materials scientists. They’re constructed from one of the toughest known natural materials: lighter, yet five times stronger than steel, and bacteria resistant to boot. Spider silk is also
