  • Pi, Anyone? A Celebration Of Math And What’s New
    It’s March 14, or Pi Day, that day of the year where we celebrate the ratio that makes a circle a circle. The Greek letter that represents it is such a part of our culture that it merits our irrational attention.Joining Host Ira Flatow to help slice into our pi’s is Dr. Steven Strogatz, professor of math at Cornell University and co-host of Quanta Magazine’s podcast “The Joy Of Why.” They talk about how pi was “discovered,” the ways it’s figuring into recent science, and how AI is changing the field of mathematics.Transcripts for each segment will be available after the show airs on sciencefriday.com.

  • How Plants Powered Prehistoric Giants Millions Of Years Ago
    When you imagine prehistoric life, it’s likely that the first thing that comes to mind are dinosaurs: long-necked Apatosauruses, flying Pterosaurs, big toothy Tyrannosaurs. But what don’t get as much attention are the prehistoric plants that lived alongside them.Plants, shrubs, and trees played a key part in the food chains of dinosaurs, and many dinosaurs evolved to match the plant life available to them. The Apatosaurus’ long neck, for example, developed to reach leaves high up in prehistoric trees.Joining Host Flora Lichtman to defend the importance of prehistoric plants is Riley Black, author of the new book When the Earth Was Green: Plants, Animals and Evolution’s Greatest Romance. She’s based in Salt Lake City, Utah.Read an excerpt from When the Earth Was Green at sciencefriday.com.Transcripts for each segment will be available after the show airs on sciencefriday.com.

  • How Narwhals Use Their Tusks To Hunt And Play | This Week's ‘Blood Moon’ Lunar Eclipse
    An international team of researchers used drones to study narwhals and learn more about their behavior. And, a total lunar eclipse will be visible across most of North and South America in the early morning hours of March 14.New Footage Shows How Narwhals Use Tusks To Hunt And PlayWe’re taking a polar plunge into the science of sea unicorns, also known as narwhals!Narwhals are mysterious arctic whales with long, twirly tusks protruding from their foreheads, like a creature out of a fairy tale. And it turns out that we don’t know too much about them, partly because they live so far north in the remote Arctic.An international team of researchers used drones to observe narwhals in the wild and learned new things about their behavior, including how they use their tusks to hunt and play.Host Flora Lichtman gets on the horn with Dr. Gregory O’Corry-Crowe, research professor and biologist at Florida Atlantic University, who was an author on the new narwhal study, published last month in Frontiers in Marine Science.How To See The ‘Blood Moon’ Lunar Eclipse This WeekEarly on Friday, March 14 (or super late on Thursday, March 13, depending on your time zone) people across the U.S. will be able to watch a total lunar eclipse, if skies are clear. The partial eclipse will begin at 1:09 a.m. Eastern time on Friday the 14th, with totality lasting from 2:26 to 3:31 a.m. Eastern.Astronomer Dean Regas joins Host Flora Lichtman to tell us what to expect, and share some tips for comfortable lunar eclipse viewing.Transcripts for each segment will be available after the show airs on sciencefriday.com.   Subscribe to this podcast.

  • Where Have All The Butterflies Gone?
    A sweeping new study on one of the most beloved insects, maybe the only truly beloved insect—the butterfly—details its rapid population decline in the United States. The new research, published in the journal Science widens the butterfly net and looks at how more than 500 species have fared over the past 20 years.Researchers found that many populations are taking a nosedive. What’s causing the downswing, and is there anything we can do?Host Flora Lichtman talks with two of the study authors, Dr. Elise Zipkin, Red Cedar distinguished professor of quantitative ecology and director of the ecology, evolution and behavior program at Michigan State University; and Dr. Nick Haddad, professor of integrative biology also at Michigan State University in East Lansing, Michigan.Transcripts for each segment will be available after the show airs on sciencefriday.com.

  • What Does Dismantling USAID Mean For Global Health?
    On the very first day of Donald Trump’s second term, he signed an executive order targeting foreign aid programs, especially the U.S. Agency for International Development (USAID).Comprising less than 0.1% of the federal budget, USAID provides international humanitarian and development aid for poverty eradication, education, disease prevention, and medical programs. The Trump administration has cut off funding for these programs and most of the USAID staff was placed on leave or laid off.Since January, hospitals and clinics in places like Thailand, Syria, and India have shuttered; clinical trials on HIV and maternal health have been canceled; and projects on polio, malaria, and tuberculosis prevention have been stopped.Then, this week, the Supreme Court rejected a bid to keep some aid funds frozen. But what does that mean in practice for USAID’s global health initiatives?Host Flora Lichtman talks about the global health implications of dismantling USAID with Dr. Atul Gawande, surgeon and former head of global health at USAID; and Dr. Salim Abdool Karim, epidemiologist and director of the Centre for the AIDS Programme of Research in South Africa.Transcripts for each segment will be available after the show airs on sciencefriday.com.
