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.Transcripts for each episode are available within 1-3 days at sciencefriday.com.Subscribe to this podcast.

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.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

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.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

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.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
