The counterintuitive science of hunting and wildlife survival
1+ day, 2+ hour ago (520+ words) For most of the past century, wildlife scientists have mainly treated hunting as a threat to be contained. The worry was that pulling animals out of a population makes it shakier, prone to booms, busts, and eventual collapse. A study…...
Scientists found signs that a fault in T'rkiye made its own CO2 during an earthquake
1+ day, 17+ hour ago (876+ words) Carbon dioxide usually shows up in conversations about cars, factories, and volcanoes. These are slow, visible sources, operating on timescales of years or seasons. The science around them is fairly well understood. Geologists have long suspected another source " one that…...
Ancient warming pushed seagrass into colder seas, and the same story may be starting again

Ice cores show that even relatively minor volcanic eruptions can wreak global havoc
1+ week, 1+ day ago (824+ words) When aviation authorities map ash risk across the North Atlantic, Iceland dominates the picture. Oregon doesn't even make the list. A discovery in Greenland ice is changing those calculations. Tiny glass particles trapped in ancient snow have now been matched…...
Coral reefs may be more connected - and more resilient - than scientists thought
1+ week, 2+ day ago (866+ words) A new study found something that sounds almost too good to be true about coral reefs, given everything else we know about their precarious state." When a common branching coral reproduces, its offspring don't settle nearby. They drift on ocean…...
