Science Signaling Podcast

First up on the podcast, Contributing Correspondent Richard Stone joins host Sarah Crespi to talk about the toll of the ongoing conflict in Ukraine and how researchers have been mobilized to help the war effort. In June, Stone visited the basement labs where Ukrainian students modify off-the-shelf drones for war fighting and the facilities where biomedical researchers develop implants and bandages for wounded soldiers.   Next on the show, the isotopic ratios in our teeth and bones record the chemistry of what we eat. When anthropologists recently applied this technique to Neanderthals, they were surprised to find that when it comes to eating meat, our hominin cousins appeared to be on par with lions. Melanie Beasley, assistant professor of anthropology at Purdue University, has an explanation for why Neanderthals chemically look like hypercarnivores: They were just eating a lot of maggots. She talks about how she tested this idea by studying maggots that were fed putrefying human flesh.   Last up on this
