Biobanking DNA now could save species from extinction later
Native Great Lakes wildlife is at risk of extinction due in part to climate change and pollution. Before species are lost, their DNA could be “banked” for future regeneration. We talk to UW-Madison genetic professor Francisco Pelegri about the effort he’s leading to do just that.

Global study of bird songs helps explain factors behind diverse sounds
After studying more than 100,000 recordings of birds singing, UW-Madison researchers believe habitat, body size and beak shape influence their calls. Sathya Chandra Sagar joins us to talk about the study he co-authored.
