• Controversy In Yellowstone

  Thirty years ago, park rangers reintroduced grey wolves into Yellowstone National Park. They wanted to restore the ecosystem and get the elk population, which had decimated the plant community, in check. And it worked – or so the popular narrative suggests. But is it really so simple? Today on the show, we explore how the Yellowstone ecosystem has changed since wolves returned and whether those changes can really be pinned solely on wolves. Plus, how the narrative of the Yellowstone wolf legacy could affect wolf reintroduction elsewhere. (encore)Curious about other science controversies?

• What Are AI Data Centers Doing To Your Electric Bill?

  Electricity bills are on track to rise an average of 8 percent nationwide by 2030 according to a June analysis from Carnegie Mellon University and North Carolina State University. The culprits? Data centers and cryptocurrency mining. Bills could rise as much as 25 percent in places like Virginia. Science writer Dan Charles explains why electric utilities are adding the cost of data center buildings to their customers’ bills while the data companies pay nothing upfront. Read the full June analysis here.To listen to more on the environmental impact of data centers, check out our two-part reported series:- Why the true water footprint of AI is so elusive- How tech companies could shrink AI's climate footprintInterested in how technology affects everyday life?

• Who Should Track Their Blood Sugar?

  Prediabetes is common in the U.S. — around 1 in 3 people have it. And many people may not know they have it. But last year, the FDA approved the first over-the-counter continuous glucose monitor. Since then, more people without diabetes have started checking their blood glucose levels. Diabetologist and University of California, San Francisco professor of medicine Dr. Sarah Kim shares the science behind blood glucose with host Emily Kwong. Check out more of NPR’s coverage about continuous glucose monitors.Interested in more science of the human body?
