What comes to mind when you think of the ocean? Maybe a day at the beach — swimming in the waves, snorkeling through coral reefs, fishing, surfing, and sunsets that kiss the blue horizon. But Earth's oceans are more than all of that; they're our planet's defining feature, its largest ecosystem, the original source of all life, and, according to physicist and oceanographer Helen Czerski, the engine that powers our planet. On this episode, we talk with Czerski about her new book, "The Blue Machine: How the Ocean Works," and why she says the ocean is critical not only to our climate system, but to the big and small processes that sustain and shape life on Earth. She also helps us understand the many intricacies of the sea, from the reasons why it's salty to how the Earth's rotation affects its currents. We also hear stories about efforts to restore coral reefs using sound and find out why scientists are looking for climate time capsules at the bottom of the ocean.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Folge vom 24.11.2023How Gene Therapy is Offering Hope — Once AgainFor decades, the idea that you could attack genetic illnesses right at the root — that you could modify people's genes to treat or cure disease — sounded like science fiction. But in recent years, several new gene therapy treatments have been FDA approved, and many others are showing promise in clinical trials. On this episode, we take a look at what's new with gene therapy, what's on the horizon, and the challenges standing in the way. We hear stories about making these treatments more affordable by changing the manufacturing process, what happened when one family tried to enroll their son in a clinical trial under a looming deadline, and one man's DIY approach to curing his own condition. We also chat with a pioneer in the field of gene therapy about sticking with her research during a time when funding dried up and interest in the field had faded.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Folge vom 17.11.2023Changing TastesWhat we make for dinner, grab as a snack, or have for breakfast changes all the time — and there are some major forces at play: consumer tastes and marketing, but also climate change, global supply chains, nutrition science, health concerns, and social media influencers. On this episode, we'll look at what we eat and why.We'll find out how lima beans are getting a makeover, and why seed oils ended up becoming a lightning rod in nutrition debates. We'll also taste a futuristic green with self-proclaimed superpowers, meet one physician who's trying to convince people to eat more organ meats, and another who says to stay away from anything marketed as health food.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Folge vom 15.11.2023Salty, Crunchy, and Addictive: A Physician's Fight Against Ultra-Processed FoodsSugary cereals for breakfast, a protein bar as a snack, a microwave lasagna for lunch, and a frozen pizza for dinner sounds like a teenager's dream diet, but these are the types of foods physician Chris van Tulleken ate for four weeks. During this time, he got 80 percent of his daily calories from ultra-processed foods, to see how it would impact his health and mood. He writes about this experience, and his extensive research on these products in his new book, "Ultra-Processed People: The Science Behind Food That Isn't Food." Host Maiken Scott talks to Van Tulleken about the link to obesity and disease, and why he says we should probably avoid anything that's marketed as a health food.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
