The Lasting Impacts of COVID-19
It's been four years since COVID-19 struck, transforming our modern world in ways we'd never seen before — and we're still processing the aftershocks. The pandemic exposed fault lines lurking beneath the surface of our everyday lives — friendships and bonds that weren't as strong as we thought; political rifts that turned into chasms; shifts in our fundamental beliefs of who we should trust, and what rules we should follow. It showed us how fragile we are — as human beings, and as a global community.Now, we find ourselves trying to pick up the pieces — to understand what happened, and what we can do better next time. On this episode, we explore the major changes caused by the pandemic, what we can learn from them, and how we can move forward. We hear stories about one man's dogged search for a treatment for his long COVID, how the pandemic both hurt and revived the field of public health, and how to repair relationships that became frayed or broken by the pressures of the pandemic.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

The New Mental Health Landscape
Know the signs of depression. Recognize symptoms of anxiety. Pay attention to your friend's changing moods. There's been a push to raise mental health awareness for decades, and now, the topic is everywhere. It's leading the charts on social media sites, and everybody from celebrities to politicians to sports superstars are talking about it more openly. At the same time, it seems like our overall mental health is declining, as more and more people report having mental health issues. On this episode, we explore how the field of mental health is changing and adapting. We'll find out what traditionally trained therapists make of mental health advice on social media, why some experts argue that too much awareness can backfire, and why mental illness can be so tricky to diagnose.

Atomic Angst and the Teenage Spy
In 1944, a brilliant, young Harvard physics student named Ted Hall was recruited to work on the super-secret mission that had already assembled the country's top scientists: the Manhattan Project. Soon, Hall was on his way to Los Alamos, where he worked on the implosion mechanism for the nuclear bomb. As the project started to succeed, Hall became increasingly concerned that it would spell disaster for the world, especially if the U.S. were the only country to have nuclear capacity. So, at the age of 18, Hall decided that he needed to do something, and he became a spy for the Soviets. Hall may have been an incredible physicist, but he was not the stealthiest of spies. Still, he was never officially caught or charged. On this episode, investigative journalist Dave Lindorff details why Ted chose this path and how he managed to evade intelligence agencies. Lindorff's new book is called, "Spy for No Country: The Story of Ted Hall, the Teenage Atomic Spy Who May Have Saved the World." We'll also hear about the state of America's nuclear arsenal today and find out why some experts argue it needs a big upgrade.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

All the Rage
You can feel it coming on — your face flushes hot, maybe your fists clench, your heartbeat speeds up and blood pressure rises. It's rage — and it can go from zero to red-hot in a matter of seconds. Best-case scenario, it disappears just as fast. Worst-case scenario — it completely takes over. It's normal to feel angry when you or somebody else has been wronged, mistreated, or hurt. But even justified rage can become destructive, like a wrecking ball ruining careers and relationships. So, how do we handle these fiery emotions when they erupt? On this episode — how to deal with anger and rage. We learn about healthy ways of expressing our ire; the rise of "rage rooms" and what psychologists have to say about them; and what causes toddlers to throw such terrible tantrums.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Setting the Medical Record Straight
Medical records are an important part of health care. They create a history of past issues, test results, and medications. They paint a picture of somebody's general health. Patients now have more access than ever before to their records, and these changes have come with some growing pains — like receiving test results straight from the lab, before their doctor can review them, or discovering mistakes. On this episode, we crack open those medical records to get a better sense of how they can help and hinder care. We'll hear about how physicians struggle to access different parts of the record to create a cohesive picture of a patient's health. We dig into issues around law enforcement accessing these records, and why they're so valuable to hackers.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Inside Facebook: A Conversation with Jeff Horwitz
After covering the 2016 U.S. presidential election, reporter Jeff Horwitz knew that "something really weird was going on," that social media sites, especially Facebook, had played a role in shaping the election. But how — exactly? In his new book, "Broken Code: Inside Facebook and the Fight to Expose Its Harmful Secrets," Horwitz details his chase to crack open this notoriously secretive black box that is Facebook. Host Maiken Scott talks to Horwitz about the powerful algorithms that favored engagement above all else, that not just amplified specific content, but started to shape everything from what we see, to what we post, to how politicians design their campaigns. Horwitz covers technology for The Wall Street Journal and was one of the reporters on the award-winning series "The Facebook Files."Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

When Healing Happens But We Don't Know Why
More than a third of Americans use complementary and alternative medicine, ranging from acupuncture to herbalism, Ayurveda to homeopathy. But despite its growing popularity, complementary and alternative medicine remains, for the most part, outside the Western medical mainstream — regarded by some as fringe, and by others as straight-up quackery. Despite that, many researchers and supporters have been trying to gain a deeper understanding of medical practices from around the world, and to incorporate them into our health care system. And that's led to more questions: Which practices work, and for what conditions? How do they work? And how do we measure and standardize treatments when they're removed from their cultural contexts? On this episode, we step outside the boundaries of Western medicine to explore those questions. We hear stories about a mysterious Vodou treatment, the struggle to bring acupuncture into the medical mainstream, and answers to Western skeptics.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
