This month, the Department of Health and Human Services terminated almost $500 million in mRNA vaccine development grants and contracts. While HHS has said that these cuts won't affect mRNA cancer research, some researchers have expressed concern about the impact on their ongoing work. In light of these developments, we’re revisiting a conversation from February.A team at Memorial Sloan Kettering is developing an mRNA vaccine for pancreatic cancer, which is notoriously difficult to treat.

2025/08/20

Fireflies’ magical blinking lights are tiny beacons in the warm dark night. Who can resist catching one? Not scientists.Because their light comes from bodily chemicals, fireflies’ power of illumination has long been used as a tool in medical research. And that has driven scientists to investigate the inner workings of the blinking beetle itself. Researchers have recently discovered that fireflies’ glowing lanterns are only one of the ways they communicate. Host Ira Flatow talks with entomologist

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

2025/08/04

For almost their entire 4.5 billion-year existence, Earth and its moon have been galactic neighbors. And the moon isn’t just Earth’s tiny sidekick—their relationship is more like that of siblings, and they’re even cut from similar cosmic cloth.Without the moon, Earth and its inhabitants wouldn’t be what they are today: The climate would be more extreme, lunar tides wouldn’t have given rise to life on Earth, biological rhythms would be off-beat, and even timekeeping and religion would have evolved

Paleontologists have identified an ancient reptile with a towering crest made not of skin, or scales, or feathers, or antler—but something else entirely. It’s some kind of integumentary outerwear we’ve never seen before. The small creature sporting the curious crest was named Mirasaura grauvogeli, and it lived during the Middle Triassic period, about 247 million years ago, just before dinosaurs evolved. Host Flora Lichtman talks to evolutionary biologist Richard Prum about this dramatic dorsal

It’s shaping up to be one of the worst tick years yet, and concerns about Lyme disease—which is transmitted through the bites of some species—are high. Aside from a short-lived vaccine released in the late 1990s, people have not had the opportunity to get vaccinated against Lyme disease. But if our dogs can get vaccinated, why can’t we?
