Mosquitoes make a different sound from other flies their size because they beat their wings twice as fast as other insects their size. With such a high frequency, you knew something weird had to be going on.
This week we learn a lot about Neanderthals from the DNA in the crap in their teeth. There’s some neat stuff here.

This week it’s a great story about “ant-loving” (i.e. ant parasitizing) beetles that hide among army ants by looking and acting and smelling like one of them. This has evolved independently multiple times, even though the rove beetles are a very old group with lots of time diverge.
