Using what I presume to be the world's smallest MRI machine scientists have figured out which part of a Japanese honey bee's brain is used to cook predatory wasps to death. Yep, when a certain sort of wasp invades a hive of this sort of bee, they form a "bee ball" around it, cooking it until it keels over. This is the only sort of honeybee that's known to do this, so naturally they're going to be killing a whole bunch of wasps trying to figure out what makes it tick. I hate wasps, so I'm OK with this!
