PubSci Playback is a podcast based on Brookhaven National Laboratory’s live science and café series, PubSci. Since 2014, PubSci has been offering the public a chance to see a more casual side of the groundbreaking science happening every day at Brookhaven Lab, one of the 17 U.S. Department of Energy national labs. The series hops around Long Island, NY, bringing Brookhaven scientists and their collaborators at other research institutions together with an audience—typically in a pub or restaurant setting—for informal discussions about Brookhaven’s research.
