Ashley Blowis describes in science advances this week,

lunge feeding whales use much less energy

than anyone predicted.

Now we have David Grimm.

He's the online news editor for science.

And he's brought us some fun stories this week. Hi, Dave. Hey, Sarah. The first one that we're going to talk about rang some bells for you. Maybe other people have heard of this. I kind of seen this a lot on social media. Everything is turning into crabs. This is called carcinization. Have you heard of that before? This I not. No, I actually hadn't.
