Scientists have named a prehistoric crocodile described as "one of the nastiest sea creatures to have ever inhabited the earth" after late Motorhead frontman Lemmy Kilmister. London's Natural History Museum said the fossil of what's now known as Lemmysuchus obtusidens was dug up in England in the early 20th century but was incorrectly categorized with other sea crocodiles found in the area. Researchers recently gave it a new classification and a scientific name of its own. Curator Lorna Steel said "we'd like to think that [Kilmister] would have raised a glass to Lemmysuchus."

Deaths from lightning are way down in U.S.

Lightning — once one of nature's biggest killers — is claiming far fewer lives in the United States, mostly because we've learned to get out of the way. In the 1940s, when there were fewer people, lightning killed more than 300 people annually. So far this year, 13 people have died after being struck, on pace for a record low of 17 deaths. Lightning strikes have not changed — they hit about the same amount as they used to. But fewer of us are outside during bad weather. If we're not huddled indoors, we're often in cars. Vehicles with metal roofs — not convertibles — are safe from lightning, experts say.

91 new volcanoes found under Antarctica

University of Edinburgh researchers announced the discovery of 91 previously unknown volcanoes under west Antarctica. The volcanoes themselves aren't likely to have any major effect, but if the ice sheet above them melts, it could trigger an eruption, researchers said. In a worst-case scenario, we could see a feedback loop of melting ice that destabilizes volcanoes, which erupt and melt more ice, and so on.

Scent of plastic makes fish think it's food

Plastic ending up in the bellies of fish may not be an accident. A new study finds that anchovies were actually attracted to some kinds of plastic, mistaking it for a meal. Researchers tested different odors on wild schools of anchovies that had been caught off California. They soaked different substances in seawater: krill; "biofouled" plastic coated in algae and bacteria (which happens when plastic enters the ocean); and clean plastic. When the fish sensed the krill-flavored water, they bunched up to focus on the potential food source. They didn't react that way to the clean plastic, but they did cluster around the biofouled plastic. So plastic in the ocean could indeed be attractive to fish because of the algae that live on it.
