The real da Vinci code, and the world’s oldest poison arrows

Science Magazine Podcast

First up on the podcast, scholars are on a quest to find Leonardo da Vinci’s DNA. With no direct descendants, the hunt involves sampling the famous polymath’s papers, paintings, and distant cousins. Contributing Correspondent Richard Stone talks with host Sarah Crespi about what researchers hope to learn from Leonardo’s genes and the new field of “arteomics.” Next on the show, new evidence for poisoned arrows from 60,000 years ago complicates our picture of hunting during the Pleistocene. Sven Isaksson, a professor of archaeological science at Stockholm University, joins the podcast to discuss the discovery of poisonous residues on microliths—the tiny, worked stone points used on arrows and spearheads. These findings could push back the origins of this toxic technology by 50,000 years. This week’s episode was produced with help from Podigy.
