  • The Science Of Replacing Body Parts, From Hair To Hearts
    It seems like every week, there’s a new headline about some kind of sci-fi-esque organ transplant. Think eyeballs, 3D-printed kidneys, pig hearts.In her new book, Replaceable You: Adventures in Human Anatomy, science writer Mary Roach chronicles the effort to fabricate human body parts—and where that effort sometimes breaks down. Host Flora Lichtman speaks with Roach about everything from hair transplants to 3D-printed hearts, and why our anatomy is so hard to replicate in the first place.Guest: Mary Roach is a science writer and the author of Replaceable You: Adventures in Human Anatomy.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

  • It’s Not Just You—Bad Food Habits Are Hard To Shake
    Remember “The Biggest Loser”—the show where people tried to lose as much weight as quickly as possible for a big cash prize? The premise of the show was that weight loss was about willpower: With enough discipline, anyone can have the body they want.The show’s approach was problematic, but how does its attitude toward weight loss match our current understanding of health and metabolism? The authors of the book Food Intelligence, nutrition scientist Kevin Hall, who studied “Biggest Loser” contestants at the NIH; and science writer Julia Belluz, join Host Flora Lichtman and answer listener questions about nutrition, diet fads, and metabolism.Read an excerpt of Food Intelligence: The Science of How Food Both Nourishes and Harms Us.Guests:Julia Belluz is a science journalist based in Paris.Dr. Kevin Hall is a nutrition scientist and former NIH researcher based in Kensington, Maryland.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

  • 100 Years Later, Quantum Science Is Still Weird
    In July 1925, physicist Werner Heisenberg wrote a letter to Wolfgang Pauli sharing his new ideas about what would eventually become known as quantum theory. A hundred years later, that theory has been expanded into a field of science that explains aspects of chemical behavior, has become the basis of a new type of computing, and more. But it’s still really weird, and often counterintuitive. Physicist Chad Orzel joins Host Ira Flatow to celebrate 100 years of quantum science, and separate quantum fact from science fiction.Guest: Dr. Chad Orzel is the R. Gordon Gould Associate Professor of Physics and Astronomy, and chair of the department, at Union College in Schenectady, New York.Transcripts for each episode are available within 1-3 days at sciencefriday.com.  Subscribe to this podcast.

  • An Off-The-Grid Nobel Win, And Antibiotics In Ancient Microbes
    This year’s Nobel Prize in Physiology or Medicine went to three people whose combined discoveries outlined the role of the peripheral immune system—how the immune system knows to attack just foreign invaders and not its own tissues and organs. But when the phone rang for Shimone Sakaguchi, Mary E. Brunkow, and Fred Ramsdell, only two of them picked up.Host Ira Flatow talks with Nobel Prize winner Fred Ramsdell, co-founder and scientific advisor at Sonoma Biotherapeutics.Plus, Ira talks with bioengineering professor César de la Fuente, who looks for solutions to the antibiotic resistance crisis in unexpected places. Now, he’s used AI to help identify promising antibiotic candidates lurking in ancient archaea, small organisms that can survive some of the most extreme conditions in the world.Guests:Dr. Fred Ramsdell is the co-founder and scientific advisor at Sonoma Biotherapeutics.Dr. César de la Fuente is an associate professor of bioengineering at the University of Pennsylvania.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

  • World Space Week And Promising Climate Tech Companies
    It’s World Space Week, and we’re fueling up the rocket for a tour of some missions and projects that could provide insights into major space mysteries. Astrophysicist Hakeem Oluseyi joins Host Flora Lichtman to celebrate the wonders of space science, from the recently launched IMAP, which will study the solar environment, to the new Vera Rubin Observatory, and big physics projects like LIGO. Plus, the latest in climate tech: MIT Technology Review has published its annual list of climate tech companies that show great promise in work ranging from producing sodium ion batteries to recycling rare earth magnets. Host Ira Flatow talks with climate reporter Casey Crownhart about trends in climate tech and what companies she’s excited about.Guests: Dr. Hakeem Oluseyi is an astrophysicist and author of the upcoming book, Why Do We Exist? The Nine Realms of the Universe That Make You Possible, and host of the video podcast “Particles of Thought.”Casey Crownhart is a senior climate reporter for MIT Technology Review based in New York City.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
