    Sitting all day is terrible for us. Moving a little can help
    Keeping your butt in a seat for hours a day increases the risk of heart attacks, diabetes, psychiatric conditions, and more. But in our tech-filled world, many of us lead sedentary lives, whether because of school, work, or leisure. Researchers set up an experiment to see how much movement would make a difference for people who spend their days at a desk—and 23,000 people signed up. Joining Flora to tell us what they found is tech journalist Manoush Zomorodi, author of “Body Electric: The Hidden Health Costs of the Digital Age and New Science to Reclaim Your Well-Being.” Read an excerpt of “Body Electric.” Guest:  Manoush Zomorodi is host of NPR’s TED Radio Hour and author of “Body Electric: The Hidden Health Costs of the Digital Age and New Science to Reclaim Your Well-Being.” Other episodes you may enjoy: 8.5 Hours Of Daily Sitting Linked To Higher BMI And Cholesterol How Is Screen Time Affecting My Kid?

    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.  In August 2025, the 80th anniversary of the bombings of Hiroshima and Nagasaki, he spoke 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.

    What do people eat? Plant and animal DNA in sewage provide clues
    Imagine you wanted to get a general idea of what people are eating in a given community. You could look at grocery store sales, or do surveys, but neither can capture a complete picture.  Microbiome researcher Lawrence David and his lab look to another source of data: genetic material in sewage water. It turns out that detectable DNA signatures of individual plant and animal species remain behind even after they’ve been eaten, digested, excreted, and flushed down the toilet. He joins Host Flora Lichtman to describe his “Edible Atlas” project, the backend limitations of sewage analysis, and where the research might go.  Guest:  Dr. Lawrence David is an associate professor of molecular genetics and microbiology in the Center for Genomics and Computational Biology. He runs the Edible Atlas project at Duke University.

    3D images of galaxies will rock you (ft. Queen)
    "Is this the real life? Is this just fantasy? Caught in a landslide, no escape from reality. Open your eyes, look up to the skies and see." There’s something about space that captures the imagination of scientists and artists alike. Just ask astrophysicist Derek Ward-Thompson and astronomer Brian May (yes, THAT Brian May, guitarist of Queen). In their book "Islands in Infinity: Galaxies 3-D," they turn flat images of the galaxies to three dimensional spacescapes that leap off the page. In March, Host Flora Lichtman spoke with Ward-Thompson and May about the enchanting nature of space and the collision of art and astronomy. And yes, they get into the music. Guests:  Dr. Brian May is an astronomer and the guitarist of Queen. Dr. Derek Ward-Thompson is an astrophysicist at the University of Lancashire in England.
