For centuries, researchers knew that Euglenids, a diversified family of aquatic unicellular organisms, could reshape their bodies in any number of elegant ways but no one knew why they did it. Some researchers think they now know: “Amongst biophysicists, metaboly was thought to be a way to swim in a fluid, where these cells live,” […]

Researchers: “profound yet intuitive: Every species has evolved backup plans”

To study this “interactome,” researchers collecting data on 9 million protein interactions among species: The scientists studied 1,840 species – from bacteria to primates – to understand how evolution built life forms that could survive in the face of natural adversities. What they discovered was profound yet intuitive: Every species has evolved backup plans that […]
