The uncertain future of North America’s ash trees, and organizing robot swarms
Podcast: Science Magazine PodcastPublished On: Thu Jan 07 2021
Description: Freelance journalist Gabriel Popkin and host Sarah Crespi discuss what will happen to ash trees in the United States as federal regulators announce dropping quarantine measures meant to control the emerald ash borer—a devastating pest that has killed tens of millions of trees since 2002. Instead of quarantines, the government will use tiny wasps known to kill the invasive beetles in hopes of saving the ash. Sarah also talks with Pavel Chvykov, a postdoctoral researcher at the Massachusetts Institute of Technology, about the principles for organizing active matter—things like ant bridges, bird flocks, or little swarms of robots.
