Why Swedish scientists gave salmon cocaine

Why Swedish scientists gave salmon cocaine

A recent study [https://doi.org/10.1016/j.cub.2026.03.026] caught our eye: salmon on cocaine. Or really, researchers giving salmon cocaine…for science. See, scientists know human drugs pollute aquatic environments – past studies have shown even anti-anxiety drugs [https://doi.org/10.1126/science.1226850] can change how fish act. But illicit drugs are less studied. And Jack Brand [https://www.slu.se/en/profilepages/b/jack-brand/], an aquatic ecologist at the Swedish University of Agricultural Sciences, wanted to know how illicit drugs like cocaine might change fish behavior, like foraging and mating. To answer that question, Jack and his team gave salmon cocaine.  Interested in more science? Email us your question at shortwave@npr.org [shortwave@npr.org].

Without this pill, lots of people would be dead

25 years ago, the FDA approved a pill that would change the way scientists treat cancer … for good. The pill was called Gleevec; it was designed specifically to treat CML, chronic myeloid leukemia, and it was one of the first targeted cancer therapies available. A quarter century after approval, it’s still being prescribed, as are second, third and fourth-generation drugs that followed in its footsteps. What made it so special – and so effective? Pharmaceutical correspondent Sydney Lupkin [https://www.npr.org/people/825275572/sydney-lupkin] walks us through the history of the drug, and why it’s continued to change lives for decades.

Hantavirus: the risks, the science and what you need to know

On May 2, the World Health Organization got an alarming report: People aboard a ship in the Atlantic Ocean were falling ill. The culprit is now confirmed as hantavirus, a pathogen that some rodents carry that can infect humans in rare, but often deadly, instances. Multiple passengers have died, and more people are showing symptoms. So, we’re talking to Emily Abdoler [https://medschool.umich.edu/profile/5829/emily-abdoler], an infectious disease doctor at the University of Michigan, about the news – how common is hantavirus in humans, what are the consequences of getting it, and how can at-risk people protect themselves from it?  If you found this episode interesting, listen to our episode on Rocky Mountain spotted fever.

How science is taking tripping mainstream

President Trump recently signed an order to speed up the evaluation of psychedelics to treat the brain. That’s coming after decades of strict prohibition on psychedelic drug use dating back to President Nixon. So how did we go from that to a psychedelic renaissance? A look into a key institution in the world of psychedelic research may give us some clues. This episode, NPR’s brain correspondent Jon Hamilton [http://google.com/search?q=jon+hamilton&rlz=1C1GCFQ_enUS1162US1163&oq=jon+hamilton&gs_lcrp=EgZjaHJvbWUqCggAEAAY4wIYgAQyCggAEAAY4wIYgAQyBwgBEC4YgAQyBwgCEAAYgAQyBwgDEAAYgAQyBwgEEAAYgAQyBwgFEAAYgAQyBwgGEAAYgAQyBwgHEAAYgAQyBwgIEAAYgAQyBwgJEAAYgATSAQgxNDIyajBqN6gCALACAA&sourceid=chrome&ie=UTF-8] shares insight from a recent trip.

This medical condition stumped doctors for years

One morning, Kyla Madonna Kenney woke up and her world was turned upside down: The room was spinning, she had a splitting migraine and one side of her body was shaking. Her tremors and migraine lasted for days. And for years afterwards, doctors would ask her: Did anything upset you recently? Are you stressed? Have you talked to a therapist about your anxiety? She underwent surgeries and took medications that were, in hindsight, unnecessary. It wasn’t until seeing Dr. David Perez [https://researchers.mgh.harvard.edu/profile/1926181/David-Perez], a neurologist who is also a psychiatrist, that she finally got the right treatment for her medical condition, functional neurological disorder. Today, we dig into this disorder – what it is, why it’s so unknown despite being a top reason people seek out neurologists and what this condition reveals about the consequences of siloing medicine.
