Simple rules guide how proteins assemble and evolve, study finds

Researchers at Ben-Gurion University of the Negev have identified simple rules that explain how complex protein structures assemble correctly and remain functional over time, despite having many theoretically possible configurations. ...

Video shows that sunbirds suck, while hummingbirds don't

Two unrelated groups of nectar eaters, hummingbirds and sunbirds, have evolved different techniques to slurp the sweet liquid from flowers. The tongue suctioning employed by sunbirds is unique among vertebrates, according ...
