Science Friday Folgen

Put on your party hat and wet suit because it is Cephalopod Week, Science Friday’s annual celebration of all things, octopuses, squid, and cuttlefish. To kick things off, we’re bringing you an ode to the octopus arm. You may have heard that octopuses can use their arms to “taste” their surroundings, which they use for finding food. Now, researchers have unlocked a key mechanism in the octopus sensory system. Octopuses use their suckers to detect harmful microbes on the surface of crab shells or even their own eggs.  Host Flora Lichtman talks with molecular biologist Nicholas Bellono about the latest in octopus sensory science. Guest: Dr. Nicholas Bellono is a professor of molecular and cellular biology at Harvard University.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

On August 27, Health Secretary Robert F. Kennedy Jr. and the White House fired CDC director Susan Monarez after only a month on the job. Right after she was ousted, other senior leaders resigned from the agency, including Demetre Daskalakis, an infectious disease physician and former director of the National Center for Immunization and Respiratory Diseases at the CDC.Dr. Daskalakis speaks with Host Flora Lichtman about the state of the agency and what these developments mean for public health.Guest: Dr. Demetre Daskalakis is the former director of the National Center for Immunization and Respiratory Diseases at the CDC.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Earlier this summer, astronomers discovered something strange whizzing past Jupiter: an interstellar object. Scientists named it 3I/ATLAS. It’s only the third interstellar object ever observed, and it’s due to leave the solar system by the end of the year, so the race is on to learn as much as we can about it. Host Flora Lichtman talks with astrochemist Stefanie Milam about what this object could teach us about other solar systems—and ours.And, for the past two years, researchers have been studying samples from the near-Earth asteroid Bennu, trying to tease out details about its origins, and what they tell us about our solar system. Researcher Jessica Barnes describes a new analysis of Bennu samples that found stardust, the residue of ancient exploding stars, older than our solar system.Guests: Dr. Stefanie Milam is an astrochemist at NASA and a project scientist for the James Webb Space Telescope. Dr. Jessica Barnes is an associate professor in the Lunar and Planetary Laboratory at the University of Arizona.Transcripts for each episode are available within 1-3 days at sciencefriday.com.Subscribe to this podcast.
