While on a sampling trip in California’s Lassen Volcanic National Park, researchers stopped to sample a rather boring stream on their hike to Boiling Springs Lake. But when they incubated that water sample back in the lab, they discovered an amoeba that could still move and divide at 145 F, a new record for a eukaryotic cell. Microbiologist Angela Oliverio joins Host Flora Lichtman to describe the “fire amoeba,” Incendiamoeba cascadensis.Plus, planetary scientist Johanna Teske takes us to exoplanet TOI-561b, a far-off “wet lava ball” which was recently observed by the James Webb Space Telescope. Researchers believe that the planet has the strongest evidence yet of an atmosphere on a rocky planet outside our solar system.Guests:Dr. Angela Oliverio is an assistant professor in the department of biology at Syracuse University. Dr. Johanna Teske is a staff scientist at Carnegie Science Earth and Planets Laboratory in Washington, D.C.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
