Joseph Dituri has already broken the world record for the longest time living underwater, and he’s not coming up for air just yet! He’s spending 100 days living in a lagoon, and has made a science experiment of his experience! Join SciFri for an interview—and a glimpse into his underwater home—with "Dr. Deep Sea" and Sarah Spelsberg, MD, medical lead for Project Neptune 100, on how they hope the study of his body and mind can help health researchers back on land understand the effects of compression on the human body. --- Because of the COVID-19 protections still in place, Science Friday is often pre-recorded, so we’re not always able to take your calls. We miss having your voices on our radio program—so we’re inviting our listeners to join us live for select recordings for #ScienceFriday​​ on the radio! The event was recorded on Friday, June 2, 2023. The segment airs on the radio and our podcast on Friday, June 9, 2023. If you'd like to join future live Zoom call-ins to get your questions on the air with us, sign up for updates: https://www.sciencefriday.com/articles/join-live-recording-online/
