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 a detailed, musculoskeletal model of an echidna forelimb, Harvard scientists are not only shedding light on how the little-studied echidna’s forelimbs work, but also opening a window into understanding how extinct mammals might have used those limbs.

A paper by Harvard researchers wonders whether the interstellar object known as “‘Oumuamua” is a visitor from an alien civilization.

Harvard researchers contribute to the preservation of museum specimens, marking the collections’ importance in a special journal released Nov. 19.

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.

Based on close examination of thousands of fossilized fish teeth, a Harvard researcher found that, while the asteroid impact that killed off the dinosaurs did lead to the extinction of some fish species, it also set the stage for two periods of rapid evolution among marine life.
