Podcast: Bringing back tomato flavor genes, linking pollution and dementia, and when giant otters roamed Earth

This week, we chat about 50-kilogram otters that once stalked southern China, using baseball stats to show how jet lag puts players off their game, and a growing link between pollution and dementia, with Online News Editor David Grimm. Also in this week’s show: our very first monthly book segment. In the inaugural segment, Jen Golbeck interviews Helen Pilcher about her new book Bring Back the King: The New Science of De-extinction. Plus Denise Tieman joins Alexa Billow to discuss the genes behind tomato flavor, or lack thereof.   Listen to previous podcasts.    [Image: Dutodom; Music: Jeffrey Cook]
