By examining the teeth of Neanderthal infants, a team of researchers was able to glean insight into nursing and weaning behavior as well as winter and summer cycles. The study even found evidence that the Neanderthals had been exposed to lead — the earliest such exposure ever recorded in any human ancestor.

Using an innovative robotic platform to observe bees’ behavior, Harvard researchers showed that, following exposure to a commonly used class of pesticides, bees spent less time nursing larvae and were less social than other bees.
