Last week, astronaut James Lovell died at the age of 97. In April of 1970, he was the commander of the Apollo 13 mission, which launched with three astronauts en route to the moon. While in space, however, the craft encountered a serious problem: an explosion in one of its fuel tanks that severely damaged the craft and disabled its electrical system, prompting the famous phrase, “Houston, we’ve had a problem.” In 1995, on the occasion of the 25th anniversary of the mission, Host Ira Flatow spoke with Lovell about the historic flight and how good luck and ingenuity among the crew and mission controllers on the ground combined to bring the Apollo 13 astronauts safely back to Earth.Guest:James Lovell was a NASA astronaut and commander of the Apollo 13 mission.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

‘Underground Atlas’ Shows How Vulnerable Fungal Networks Are
Fungal networks in the soil are arguably the basis of much of life on Earth, but they’re understudied and underappreciated in the conservation world. Scientists at the Society for the Protection of Underground Networks (SPUN) are trying to fix that. They just unveiled a global map of mycorrhizal fungal networks, which highlights how widespread they are and how little protection they have. Host Flora Lichtman talks with two of the SPUN mapmakers, Adriana Corrales and Michael Van Nuland, about the importance of fungal networks and why they need more protection.Guests: Dr. Adriana Corrales is a forest ecologist and scientist with the Society for the Protection of Underground Networks. She’s based in Bogotá, Colombia.Dr. Michael Van Nuland is an ecologist and scientist with the Society for the Protection of Underground Networks. He’s based in Portland, Oregon.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Lithium May Have A Role In Causing—And Treating—Alzheimer’s
The mechanisms behind Alzheimer’s disease have eluded scientists for decades. But a new breakthrough points to lithium as a possible explanation—not only does it occur naturally in the brain, but a deficiency causes dementia in mice. This research is one of thousands of projects that have lost funding due to President Trump’s cuts to the National Institutes of Health (NIH). Host Ira Flatow speaks with Alzheimer’s researcher Bruce Yankner about this new finding, and then to epidemiologist Katelyn Jetelina and immunologist Elisabeth Marnik about the country’s “quiet engine of science,” the NIH.Guests: Dr. Bruce Yankner is professor of genetics and neurology at Harvard Medical School in Boston, Massachusetts.Dr. Katelyn Jetelina, epidemiologist and author of the Your Local Epidemiologist newsletter. She’s based in San Diego.Dr. Elisabeth Marnik is an immunologist and Director of Science Education & Outreach at the MDI Biological Laboratory in Bar Harbor, Maine.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Are Cold Plunges Actually Good For You?
If social media and certain influential podcast hosts are to be believed, cold plunges can do everything from boosting your immune system to reducing inflammation to acting as an antidote for depression. But what does the science say? Joining Host Flora Lichtman to throw at least a few drops of cold water on this science of plunging is biologist François Haman, who studies human performance and cold exposure.And, with the help of the HBO show “Last Week Tonight,” a minor league baseball team in Pennsylvania rebranded themselves the Erie Moon Mammoths. That comes just a few months after the Utah NHL franchise renamed itself the Utah Mammoth as a nod to that state’s paleontological past. So, why are mammoths back? And do they really have what it takes to be a successful team mascot? Paleontologist Advait Jukar joins Host Flora Lichtman to weigh in.Guests: Dr. François Haman is a biologist at the University of Ottawa who studies how the human body responds to extreme environments.Dr. Advait Jukar is the assistant Curator of Vertebrate Paleontology at the Florida Museum of Natural History.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

A Nagasaki Survivor And Physician Recounts His Life's Work
Dr. Masao Tomonaga was only 2 years old when the United States bombed his home city of Nagasaki. He survived, and grew up to become a physician for other survivors, known as hibakusha. He also studied hematology, and his research on leukemia and myelodysplastic syndromes was foundational for understanding how radiation affects the body. On the 80th anniversary of the bombings of Hiroshima and Nagasaki, he speaks with Host Ira Flatow about his life’s work, how hibakusha lived with the medical consequences of the bombs, and his message to the world.Guest: Dr. Masao Tomonaga is a survivor of the atomic bombing of Nagasaki and director emeritus of the Japanese Red Cross Nagasaki Atomic Bomb Hospital.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
