In this episode:00:45 Laser-guided lightningScientists have shown that a specially designed laser can divert the course of lightning strikes in a real-world setting. The team fired the laser into the sky above a communications tower high in the Swiss Alps and altered the course of four strikes. In future they hope that this kind of system could be used to protect large infrastructure, such as airports.Research article: Houard et al.News: This rapid-fire laser diverts lightning strikes09:36 Research HighlightsThe crabs that lean on bacteria to detoxify sulfur from hydrothermal vents, and how a persons’ nasal microbes might exacerbate their hay fever.Research Highlight: Crabs endure a hellish setting — with help from friendsResearch Highlight: Plagued by hay fever?
