A Photographer Captures Nature In Mind-Boggling Detail
If you’ve flipped through an issue of National Geographic or scrolled through their social media, and caught a stunningly detailed photo of a tiny creature—like one where you can make out the hairs on a honeybee’s eyeballs, or the exact contours of a hummingbird’s forked tongue—you have probably seen the work of Anand Varma. He’s an award-winning science photographer, a National Geographic Explorer, and the founder of WonderLab, a storytelling studio in Berkeley, California.Varma speaks with Host Flora Lichtman and takes us behind the lens to show what it takes to capture iconic images of creatures that are so often overlooked.Guest: Anand Varma is a science photographer, a National Geographic Explorer, and the founder of WonderLab. He’s based in Berkeley, California.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

How Shoddy Science Is Driving A Supplement Boom
Dietary supplements are big business, with one recent estimate showing the industry is worth almost $64 billion in the United States alone. Take a casual scroll through your social media and you’ll find influencers hawking all kinds of supplements. But how effective are they? How are they regulated? And why are these “natural” remedies so appealing to millions of Americans? To size up the science and culture of supplements, Host Flora Lichtman talks with supplement researcher Pieter Cohen, and Colleen Derkatch, author of Why Wellness Sells: Natural Health in a Pharmaceutical Culture. Guests: Dr. Pieter Cohen is an Associate Professor of Medicine at Harvard Medical School and an internist at the Cambridge Health Alliance where he leads the Supplement Research Program. Dr. Colleen Derkatch is the author of Why Wellness Sells: Natural Health in a Pharmaceutical Culture and professor of rhetoric at Toronto Metropolitan University.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Octopuses Use Suckers To ‘Taste’ Harmful Microbes
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.

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.
