  • Do Mitochondria Talk to Each Other? A New Look at the Cell’s Powerhouse

    Do Mitochondria Talk to Each Other? A New Look at the Cell’s Powerhouse
    2025/05/21
    Mitochondria are known as the powerhouse of the cell—but new research suggests they might be far more complex. Columbia University’s Martin Picard joins Scientific American’s Rachel Feltman to explore how these tiny organelles could be communicating and what that might mean for everything from metabolism to mental health.

    How to Make Gold, Flamingo Food Tornado, and Kosmos-482 Lands
    2025/05/19
    Soviet-era spacecraft Kosmos-482 lands, though no one is certain where. Physicists turn lead into gold. Overdose deaths are down, in part thanks to the availability of naloxone. Flamingos make underwater food tornadoes. Chimps use leaves as a multi-tool.

  • Could Freezing Arctic Sea Ice Combat Climate Change?

    Could Freezing Arctic Sea Ice Combat Climate Change?
    2025/05/16
    The year-round sea ice in the Arctic is melting and has shrunk by nearly 40 percent over the past four decades. Geoengineering companies such as Real Ice are betting big on refreezing it. That may sound ridiculous, impractical or risky—but proponents say we have to try. The U.K. government seems to agree, investing millions into experimental approaches such as Real Ice’s. Pulitzer Center Ocean Reporting Fellow Alec Luhn is taking us with him to the Arctic to see what it takes to freeze sea ice in the already freezing cold.

  • How a West Texas Outbreak Threatens Measles Elimination Status

    How a West Texas Outbreak Threatens Measles Elimination Status
    2025/05/14
    Measles was technically “eliminated” in the U.S. in 2000 thanks to high measles, mumps and rubella (MMR) vaccination rates. While prior outbreaks have made headlines, a slew of cases in West Texas is more than just newsworthy—it could cause the U.S. to lose elimination status. Associate health and medicine editor Lauren Young explains what elimination means, why measles cases are rising and how to prevent further transmission.

    Sinking Cities, Waving Cuttlefish and Falling Spacecraft
    2025/05/12
    A 1970s Soviet spacecraft is hurtling down from space—and no one knows where it will land. All 28 of the most populous cities in the U.S. are slowly sinking. Investments and overconsumption make the wealthiest 10 percent of the global population responsible for two thirds of climate-change-related warming.

  • This Podcast Was Recorded Inside a Particle Collider

    This Podcast Was Recorded Inside a Particle Collider
    2025/05/09
    We’re taking a field trip to the U.S.’s only particle collider, the Relativistic Heavy Ion Collider (RHIC), housed at Brookhaven National Laboratory. Staff scientist Alex Jentsch takes listeners through some basic terminology and interconnected technologies that help Brookhaven researchers probe questions about our unseen universe. The RHIC is winding down in preparation for the new Electron-Ion Collider, which could help us discover the secrets of the “glue” that holds visible matter together. Be sure to head over to our YouTube account to see the video version of this podcast, shot on-site at Brookhaven National Laboratory!
