Episode Details

For the first time since 1972, humans are venturing beyond Earth orbit as NASA's Artemis II crew makes its way toward the Moon — and the spacecraft was so precisely on course that mission controllers cancelled the first planned trajectory correction burn entirely. Back on Earth, a newly identified brain circuit may finally explain why some pain becomes chronic while other pain fades, a discovery that could transform treatment for hundreds of millions of sufferers worldwide. A massive Scandinavian study of over 100,000 people found that semaglutide — the drug behind Ozempic and Wegovy — may also reduce risks of depression, anxiety, and substance use disorders, raising urgent questions about how the drug interacts with the brain. Physicists at Drexel University were left stunned after discovering that a liquid, when stretched fast enough, doesn't flow or splash — it snaps apart like shattering glass, challenging fundamental assumptions about how matter behaves. The episode also covers shape-shifting semiconductors, a 150-year geological mystery finally solved, mysterious contaminants quietly entering our food supply, and a laser-based Wi-Fi system that hits speeds of over 360 gigabits per second at half the power of conventional wireless technology.
