Aug. 26, 2024 — Fighting cancer effectively often involves stopping cancer cells from multiplying, which requires understanding proteins that the cells rely on to survive. Protein profiling plays a critical role in this process by helping researchers identify proteins -- and their specific parts -- that future drugs should target. But when used on their own, past approaches haven't been detailed enough to ...

Aug. 26, 2024 — Who hasn't sat in a medical office, listening to computer keys clacking while their provider rapidly types up notes, wondering what they are spending so much time writing about?

Aug. 23, 2024 — A link between outgroup threats and ingroup cohesion has been considered since the time of Darwin to be an adaptation for group-based competition. During the years since, studies of all sorts -- from chimpanzees to cichlid fish to mongooses -- have found evidence supporting this view, but a crucial question has remained unanswered: what about species without strong inter-group ...

Aug. 22, 2024 — Mono Lake is a beautiful but harsh environment, its salty and arsenic-laced water home to brine shrimp, alkali flies and little else. Scientists recently discovered an unsuspected resident, however, a microscopic creature -- a choanoflagelatte -- that forms colonies that harbor their own unique bacterial microbiomes. The creature, part of the sister group to all animals, could shed light on the ...
