Addiction hijacks the brain’s reward circuitry, and current treatments often struggle to break its grip. In this episode, neuroscientist and neurosurgeon Ali Rezai of the WVU Rockefeller Neuroscience Institute explains how an experimental, noninvasive focused-ultrasound treatment aimed at the nucleus accumbens could quiet cravings so that therapy and medication work better. He also describes how wearables and AI might flag people at risk of relapse before it happens.   This podcast was produced for WVU Rockefeller Neuroscience Institute by Scientific American Custom Media, a division separate from the magazine’s board of editors.   Learn more about your ad choices.

In this episode of Science Quickly, Rachel Feltman speaks with environmental historian Edward Melillo about the tiny soybean, which has come to dominate America’s diet. When you think of soy, you may only picture a block of yummy tofu or soy milk, but this crop has quietly made its way into 60 percent of processed foods. In fact, 2026 is on track to become a record soybean harvest for the U.S. And soy doesn’t just show up on our plates: as an oil, it can power trucks, buses and even planes. Tune in to hear how this plant took over the American food system.  Recommended Reading: How Seed Oils Became Controversial—And What the Science Really Says Why corn isn’t entirely to blame for ‘corn sweat’ E-mail us at [email protected] if you have any questions, comments or ideas for stories we should cover!
