Swamp lights and bat sight

Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.

In this episode, researchers explore two spooky mysteries: the source of will-o'-the-wisps and how bats integrate vision with echolocation.

In this episode, we cover: •[00:00 ] Introduction •[00:58 ] Richard Zare's background and expertise. •[01:26 ] Richard, have you ever seen will-o'-the-wisps in the wild? •[01:31 ] What did we already know about will-o'-the-wisps before your study? •[02:42 ] How could water droplets ignite methane? •[03:24 ] Tell us about the methods of your study. How did you explore this phenomenon? •[04:17 ] What are the broader implications of your findings, beyond just will-o'-the-wisps? •[05:20 ] What are the caveats or the limitations of the study? •[05:40 ] Laura Stidsholt's background and expertise. •[06:06 ] Laura, what can you tell us about the species you studied? •[06:25 ] What instruments did you attach to the bats? •[07:03 ] How did the bats' echolocation behavior compare in dark versus lit environments? •[08:14 ] What do the results suggest about the benefits of integrating information from multiple senses while hunting prey? •[08:58 ] What do the results imply about the potential impact of artificial light on bats? •[09:43 ] Final thoughts and conclusion.
