    After CDC Director Is Ousted, More Senior Officials Resign

    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.

  2. Meet 3I/Atlas, An Object From Another Solar System

    Meet 3I/Atlas, An Object From Another Solar System

    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.

    How Common Household Products Pollute Our Indoor Air

    You have probably given some thought to outdoor air pollution, whether it’s wildfire smoke or smog from traffic. You may even check AQI measurements on your phone. But what about the air inside your home? Host Flora Lichtman talks to civil and environmental engineer Nusrat Jung, who studies indoor air pollution, about how we create toxic air without even knowing it, and what we can do to avoid it.  Guest: Dr. Nusrat Jung is a civil and environmental engineer at Purdue University.

    The Shape-Shifting Science Of Sand Dunes

    In some places, sand dunes protect shorelines from the onslaught of ocean waves. In other places, the dunes themselves are on the move, and threaten human structures. Host Flora Lichtman talks with mechanical engineer Nathalie Vriend, who studies the structure of sand dunes, about what makes a heap of sand a dune, and what scientists still hope to learn about sand. Guest: Dr. Nathalie Vriend is an associate professor in mechanical engineering and leader of the Granular Flow Laboratory at the University of Colorado in Boulder.

    Food Science Experts On Perfecting At-Home Ice Cream

    Summer may be winding down, but we’re not quite ready to let go of beach days, backyard cookouts, or ice cream cones. We love ice cream here at SciFri, so we’re pulling a few of our favorite ice cream science stories out of the freezer this week. Back in 2015, ice cream expert Maya Warren sat down with Host Ira Flatow to help us understand a science mystery of “unmeltable” ice cream that made the evening news in Cincinnati. That same summer, Ira spoke to Jeff Potter, author of Cooking for Geeks, and Brian Smith, founder of Ample Hills Creamery, who give us science-backed tips for making smooth, velvety ice cream at home.

  6. An ER Doctor Reflects On Hurricane Katrina, 20 Years Later

    An ER Doctor Reflects On Hurricane Katrina, 20 Years Later

    Twenty years ago, Hurricane Katrina made landfall in Louisiana, and the levees designed to protect New Orleans failed. Huge swaths of the city flooded, and 1,600 people were trapped inside Charity Hospital. Physician Erica Fisher was working in Charity’s emergency room at the time, and she and her colleagues fought for days to keep their patients alive. Host Flora Lichtman speaks with Dr. Fisher, now an emergency medicine physician at University Medical Center in New Orleans, about Hurricane Katrina and the vulnerability of our healthcare systems in the face of disasters. Plus, science writer Maggie Koerth joins Flora to share other science news the week, including the link between heat waves and aging, updated COVID vaccine guidelines, the ancient origins of human mucus, and the possibility that dwarf planet Ceres could once have sustained life. Guest: Dr. Erica Fisher is an emergency medicine physician at University Medical Center in New Orleans, Louisiana. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

  7. An Archaeologist And A Tattoo Artist Decipher Ancient Ink

    An Archaeologist And A Tattoo Artist Decipher Ancient Ink

    Researchers recently used near-infrared photography to get a detailed look at ancient artwork showing scenes of wild animals tangled in a fight. But these weren’t paintings on a cave wall. They were tattoos on the arms of a Siberian woman who lived 2,300 years ago. What can ancient ink tell us about our ancestors?  Sticking and poking their way into this with Host Flora Lichtman are archaeologist Aaron Deter-Wolf and his research collaborator, tattoo artist Danny Riday. Guests: Aaron Deter-Wolf is an archaeologist for the Tennessee Division of Archaeology in Nashville, Tennessee. Danny Riday is a tattoo artist and independent researcher based in Les Eyzies, France.

  8. What Lies Beneath The Outer Layers Of A Star?

    What Lies Beneath The Outer Layers Of A Star?

    You might think of a star as a mass of incandescent gas, a gigantic nuclear furnace where hydrogen is turned into helium at a temperature of millions of degrees. But researchers recently reported that they’d observed some of what lies beneath all that hydrogen and helium, at least inside one unusual supernova. The star, named supernova 2021yfj, had its outer layers stripped away, leaving behind a silicon- and sulfur-rich inner shell. Astrophysicist Steve Schulze joins Host Flora Lichtman to describe what the team spotted in the heart of a dying star. Guest: Dr. Steve Schulze is a research associate at Northwestern University’s Center for Interdisciplinary Exploration and Research in Astrophysics.
