printsetters clock + cultural bats

Wired has a nice little article on the molecular clock model being used by antiquarians to date prints/books etc. The original paper is here, describing how the properties of copperplate and woodblock degeneration (and the corresponding print quality features) can be used in a clock model to help date manuscrips. Nifty.

Also, via Afarensis (who has a cool picture), Current Biology reports that fring-lipped bats may be using social transmission mechanisms in order to learn a novel foraging behaviour (recognising frog calls as prey cues). Bats = always awesome.
