What if you you could scoop up a jar of seawater and use it to figure out what species were in that part of the ocean? Today we’re able to do that with a new scientific technique analyzing environmental DNA, or eDNA for short. In this episode, we talk to Ryan Kelly, an ecologist and lawyer at the forefront of eDNA research, about the technique itself, how it’s changing what we can learn about the ocean, and how that might impact policy.
John Holdren was President Obama’s senior advisor on science and technology for eight years. In this conversation with producer Mike Osborne, Holdren discusses Obama’s passion for science and its role in all aspects of American life. He also tells us what it’s like to testify in front of Congress, which he calls “piñata day” (it sounds fun…until you realize he’s the piñata). Mike and John end by discussing the future of science and environmental policy under the Trump administration.
