He writes about the continued onslaught of cuts, firings, and changes to the science system in the United States, and how members of the scientific community can respon...

This week on Big Biology we're sharing an episode from The Naked Scientists Podcast about how humans lost their tails. Humans, chimpanzees, gorillas and orangutans do not have tails. It sets us apart from other primates, but suggests that our shared evolutionary ancestors had them. So why did we lose them, and how? Speaking with Chris Smith, from The Naked Scientists Podcast, NYU Grossman School of Medicine's Itai Yanai explains that the way this study began was literally a pain in the &...
