This mystery begins in 1952, in the Nevada desert, when a self-taught geologist came across the skeleton of a massive creature that looked like a cross between a whale and a crocodile. It turned out to be just the beginning. Ichthyosaurs were bus-sized marine reptiles that lived during the age of dinosaurs, when this area of Nevada was underwater. Yet paleontologists found few other animals here, which raised the questions: Why were there so many adult ichthyosaurs, and almost nothing else? What could have killed them all? Paleontologist Neil Kelley says that recently, there has been a major break in the case—some new evidence, and a hypothesis that finally seems to fit. Neil talked with Short Wave co-host Aaron Scott about his theory of the case, and why it matters to our understanding of the past.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Folge vom 20.01.2023New Tech Targets Epilepsy With Lasers, RobotsAbout three million people in the United States have epilepsy, including about a million who can't rely on medication to control their seizures. For years, those patients had very limited options. But now, in 2023, advancements in diagnosing and treating epilepsy are showing great promise for many patients, even those who had been told there was nothing that could be done. Using precise lasers, microelectronic arrays and robot surgeons, doctors and researchers have begun to think differently about epilepsy and its treatment. Today on Short Wave, host Aaron Scott talks with NPR science correspondent Jon Hamilton about these advances in treating epilepsy. He explains why folks should ask their doctors about surgery — even if it wasn't an option for them a few years ago.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Folge vom 19.01.2023What Cities Should Learn From California's FloodingWinter storms have flooded parts of California, broken levees and forced thousands to evacuate. Climate change is altering the historic weather patterns that infrastructure like reservoirs and waterways were built to accommodate. Urban planners and engineers are rethinking underlying assumptions baked into buildings and water systems in order to adapt to the changing climate. Today, NPR climate correspondent Lauren Sommer walks us through three innovations happening around the country to help cities adapt to shifting and intensifying weather patterns.Heard of other cool engineering innovations?

Folge vom 18.01.2023Time Is So Much Weirder Than It SeemsTime is a concept so central to our daily lives. Yet, the closer scientists look at it, the more it seems to fall apart. Time ticks by differently at sea level than it does on a mountaintop. The universe's expansion slows time's passage. "And some scientists think time might not even be 'real' — or at least not fundamental," says NPR science correspondent Geoff Brumfiel. Geoff joined Short Wave Scientist in Residence Regina G. Barber to bend our brains with his learnings about the true nature of time. Along the way, we visit the atomic clocks at the National Institute of Standards and Technology, consider distant exploding stars and parse the remains of subatomic collisions.
