An upcoming resupply mission will carry tumor samples to the International Space Station for research. Experiments in microgravity have yielded shocking results: Some tumors triple in size in just 10 days—the kind of growth that could take 10 years on Earth. What does that mean for science, and for astronauts? Joining Ira to discuss this new frontier in cancer research are hematologist Catriona Jamieson and aerospace engineer Meenal Datta. Guests: Dr. Catriona Jamieson is a hematologist at the UC San Diego Health Moores Cancer Center in California. Dr. Meenal Datta studies the physics of cancer at the University of Notre Dame’s College of Engineering in Indiana.

Have you noticed that your newer appliances are serenading you? Many new washing machines, dishwashers, dryers, and vacuums have sonic signatures. But why? And who are the composers making music for the machines in your home? Flora talks to sonic branding experts Audrey Arbeeny, who has developed sounds for washing machines; and Joel Beckerman, who has composed for Roomba. Guests: Audrey Arbeeny is the owner and executive producer of Audiobrain. She’s composed for Whirlpool, KitchenAid, the London Olympic Games, and Microsoft’s Xbox 360. Joel Beckerman is a composer and founder of Made Music Studio, and author of “The Sonic Boom: How Sound Transforms the Way We Think, Feel, and Buy.” He’s composed for the NFL, IMAX, and the Roomba vacuum.

Scientists studying climate models say there’s a high chance this will be an El Niño year—and that we could be in for a “super” El Niño. The difference is indicated by sea surface temperatures in part of the Pacific Ocean rising a little—or a lot—above their long-term average. El Niño is one half of what climatologists call the ENSO, the El Niño-Southern Oscillation. The oscillation operates on a roughly 3-7 year cycle, changing the path of the jet stream and shifting weather conditions around the world. An El Niño year, for instance, typically brings wetter weather in the western U.S. but dryer conditions in the Pacific Northwest, and can be a drought buster for regions such as southern California. But shifting ocean currents also have the potential to affect marine ecosystems, leading to algal booms, coral bleaching, and more. Climate scientist Dillon Amaya joins Host Ira Flatow to describe the role of the El Niño in shaping world weather, and what effects a particularly strong El Niño year might have on global ecosystems. Guest: Dr. Dillon Amaya is a research scientist at the NOAA Physical Sciences Laboratory in Boulder, Colorado.

In April, the crew of Artemis II got an unprecedented tour of the far side of the moon, and they brought back a proverbial shoebox full of pictures. Lunar scientist Kelsey Young stayed on Earth, and helped guide the astronauts through their photo shoots from Mission Control. Young talks with Host Flora Lichtman about how the science team chose their shot list, how to lead distant astronauts in their scientific observations, and what researchers are learning from the images and in-the-moment descriptions captured by the Artemis II crew. Guest: Dr. Kelsey Young is the Artemis science flight operations lead for NASA's Science Mission Directorate.

When Kemi Doll was in medical school, she learned that Black women are twice as likely to die from uterine cancer as white women, and also suffer disproportionately from other uterine-related conditions. What wasn’t explained was why. Now a gynecologic oncologist, Doll has made it her mission to change these trends and improve care for Black women. She joins Flora to discuss her new book, “A Terrible Strength: The Hidden Crisis of the Black Womb and Your Survival Guide to Healing.” They explore the way systemic racism and the normalization of Black women’s pain lead to later diagnoses of uterine cancer and poorer health outcomes for a range of gynecologic conditions including fibroids, endometriosis, and heavy periods. And Doll explains the problem with using reproductive health as a synonym for uterine health. Guest: Dr. Kemi Doll is a gynecologic oncologist and professor at the University of Washington Schools of Medicine and Public Health. Other episodes you may enjoy: Endometriosis Is Common.
