10 billion snow crabs have disappeared off the Alaskan coast. Here’s why
In the eastern Bering Sea, the snow crab population plummeted after a marine heat wave in 2018. The crabs may have starved, a new study finds.

Scientists debunked a long-standing cicada myth by analyzing their guts
The lack of obvious chewing mouthparts may have made casual observers think that adult cicadas don’t need to feed. But that’s not the case.
