Summary

Can we inherit trauma from our ancestors? Studies of behavior and biomarkers have suggested the stress of harsh conditions or family separations can be passed down, even beyond one’s children. Journalist Andrew Curry joins host Sarah Crespi to discuss a possible mechanism for this mode of inheritance and mouse studies that suggest possible ways to reverse the effects. Spiky, pulsating ferrofluids are perpetual YouTube stars. The secret to these dark liquid dances is the manipulation of magnetic nanoparticles in the liquid by external magnets. But when those outside forces are removed, the dance ends. Now, researchers writing in Science have created permanently magnetic fluids that respond to other magnets, electricity, and pH by changing shape, moving, and—yes—probably even dancing. Sarah Crespi talks to Thomas Russell of the University of Massachusetts in Amherst about the about the applications of these squishy, responsive magnets. This week’s episode was edited by Podigy.
