  Black bears are moving into the neighborhood. How do we coexist?

  Sep 14, 202618 min

  Living with black bears is complicated. They’re huge, hungry, and they really don’t care about your hostas. After a long period of being overhunted, black bears are on the rebound. And as they begin returning to parts of their native ranges, they’re finding humans there, too. Reporter Cassandra Stephenson joins Flora to talk about how these interactions are playing out in southeastern states. Then, carnivore ecologist Nyeema Harris joins to discuss best practices for coexistence. Guests: Cassandra Stephenson covers issues impacting rural West Tennessee as a Report for America corps member at The Tennessee Lookout. She’s based in Nashville. Dr. Nyeema Harris is an associate professor of wildlife and land conservation at Yale University in New Haven, Connecticut. Transcript will be available after the show airs on sciencefriday.com.

  Is a shorter course of antibiotics OK? + Genetic risk of fibromyalgia

  Sep 12, 202618 min

  You’ve probably been warned that if you don’t finish that course of antibiotics, you could wind up battling antibiotic-resistant bacteria. But a growing body of research suggests that the opposite might be true. What does this mean for you and your next sinus infection? Flora talks with antimicrobial resistance expert Amy Mathers to find out. Plus, the driver of fibromyalgia, a condition that can cause debilitating chronic pain and brain fog, has been something of a mystery. Patients’ imaging and blood work often turn up normal, and many have felt dismissed by doctors. A recent large-scale study identified a group of genes associated with the disease, a breakthrough that may help doctors understand people’s risk of developing the condition and reveal something about the nature of this mysterious illness. Flora talks with Nasa Sinnott-Armstrong, one of the study’s lead authors. Guests: Dr. Amy Mathers is medical director of antimicrobial stewardship and an associate professor of medicine and pathology at the University of Virginia School of Medicine. Dr. Nasa Sinnott-Armstrong is an assistant professor of computational biology and public health at Fred Hutch Cancer Center in Washington state.

  Where are we with understanding the health effects of cannabis?

  Sep 11, 202618 min

  When states began legalizing recreational cannabis a couple decades ago, 25 million Americans said they used the drug. That number nearly tripled to 70 million by 2023. There are a lot of open questions about how it affects us. Why do some people find more pain relief from THC than traditional painkillers? Is it really better for sleep? What are the effects of long-term use? Host Flora Lichtman is joined by two scientists taking on these kinds of questions: Experimental psychologist Ryan Vandrey, who’s studied the health effects of cannabis for 26 years, and neuropsychologist Natasha Wade, who studies the effects of substance abuse on adolescent brains. She recently analyzed data from 11,000 teens to understand how cannabis affects development. Guests: Dr. Ryan Vandrey is an experimental psychologist and professor at the Johns Hopkins University Behavioral Pharmacology Research Unit and helps lead the Johns Hopkins Cannabis Science Lab. Dr. Natasha Wade is an associate professor in the Department of Psychiatry at UC San Diego and licensed clinical neuropsychologist.

  Did scientists just find a dark matter particle? Maybe

  Sep 10, 202613 min

  There’s a flashy new find in the hunt for dark matter—the stuff that makes up 85% of all matter in the universe, but we have no clue what it is. A mile under Lead, South Dakota, is a giant cauldron filled with 7 tons of liquid xenon, encased in water and surrounded by super-sensitive photodetectors. Known as the LZ detector, its job is to look for flashes of light that come from particles bumping into xenon atoms. And during its observations, the researchers saw a very weird flash—a bump that doesn’t look like it came from any particle we know of. Flora talks with physicist Richard Gaitskell about the hunt for a dark matter particle and why he’s excited about this weird little finding.  Guest: Dr. Richard Jeremy Gaitskell is a physicist at Brown University and a leading scientist in the search for particle dark matter. He is a co-founder of the Large Underground Xenon experiment. Transcript will be available after the show airs on sciencefriday.com. Subscribe to this podcast.

  Why physics and philosophy need each other

  Sep 9, 202618 min

  Once upon a time, much of what we call “science” was performed by people called “natural philosophers,” delving into mysteries of nature, physics, chemistry, and more. Physicist and author Carlo Rovelli argues that there’s still a great need for philosophy, and that the two fields can and should learn from each other in investigating reality.   Rovelli joins Host Ira Flatow to talk about big ideas in physics , and his new book, “On The Equality of All Things: Lessons on Physics and Philosophy.” Read an excerpt from “On The Equality of All Things.” Guest: Dr. Carlo Rovelli is an Italian theoretical physicist and the author of “On The Equality of Things.” Transcripts for each episode are available within 1-3 days at sciencefriday.com.
