Science online, mnemonic rats edition

Blah blah blah, Facebook, blah blah blah.
  • When life gives you parasites ... Ancient ammonoids—forerunners of modern squid and nautiluses, dealt with parasites by encasing them in pearl.
  • Evolutionary baby pictures. Bats' evolution from flightless ancestors, illustrated.
  • Note to my students: no human testing planned yet. Enhancing the levels of a particular enzyme in rats' brains helps them retain memories.
  • Discredited more than a century ago, but you get to use a "cephalometer of Anthelme." Want to make a living reading people's personalities by the bumps on their head? Maybe phrenology is for you.
  • Using foremost legs as antennae, even. Spider mimics ant surprisingly well.
  • Sensory metaphor hijinks. People are more likely to identify an ambiguously-gendered face as female when touching something soft.
  • Glass ceilings are durable. Active discrimination may not be preventing women from advancing in the sciences, but institutional biases sure are.
  • Don't panic. Panic Virus author Seth Mnookin understands the parental worries underlying vaccine denialism, but he still thinks it's a problem.
  • In case you missed it. Jesse Bering thinks homophobia might be adaptive. He's wrong.
And now, after a string of weeks without video in my Friday roundup, I give you a slow loris with a tiny umbrella.
