Managing the Challenges of Motherhood
If you look around for Mother's Day gifts, you'll probably see stuff like bubble baths, spa days, yoga classes — a whole slew of things aimed at promoting "self-care" for tireless (but actually exhausted) moms. But for a lot of overwhelmed mothers, self-care becomes just another box to tick — another item on an endless to-do list that never gets finished. The demands of modern motherhood can be overwhelming: Moms are expected to do it all and do it perfectly — even if that means compromising their own well-being. On this episode, we talk about the challenges of motherhood, and how moms can find the space and time to take care of themselves. We talk with a perinatal psychiatrist about the contradictory demands of motherhood, and why bubble baths aren't the answer; hear about an initiative to help mothers dealing with postpartum depression; and learn about the unexpected ways that motherhood changes the brain.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Neurotech and the Growing Battle for Our Brains
Have you ever wanted to figure out when you're the most focused? Or how your moods change throughout the day? How "fit" your brain is, or whether your insomnia is really as bad as you think? Neurotech devices promise to deliver insights. These are cutting-edge gadgets that pick up on the electrochemical signals inside of our brains, and are connected to algorithms that analyze and interpret that data. Brain technology offers all kinds of exciting possibilities — from treating conditions like epilepsy or depression, to simply maximizing our brain health. But medical ethicists are already raising the alarm about potential dangers — for example, how are employers using this tech to monitor their employees? What happens when their brain metrics don't meet standards? On this episode, we dive into some of these thorny questions with leading scholars and researchers in the field of neurotechnology.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Why Rejection Hurts So Much — And How to Cope
Rejection, or even the thought of it, can strike fear into our hearts, and leave a bad taste in our mouths. It often leads to a mix of sadness, shame, anxiety, and anger — along with nagging questions. What's wrong with me? Why did this person not like me? Why didn't I win this award? Why didn't I get the job? But it doesn't have to be that way, and there's a lot we can learn from not making the cut. On this episode, we explore the experience of rejection — what it feels like, how it functions, and the lessons we can draw from it. We'll hear from a fear and anxiety researcher about the evolutionary roots of anxiety — and why asking someone out on a date can feel like a life-or-death situation. Then we'll explore a common experience among people with ADHD, known as rejection sensitive dysphoria (RSD), and hear how one future physician dealt with the worst rejection of her life.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Why We Love and Hate Exercising —And How to Do it Either Way
We all know that exercise is good for us — for both our bodies and our minds — but motivating yourself to hit the gym, take a run, or even go for a walk sometimes feels like the hardest thing in the world. There are constant rebuttals that arise in our minds: We're too busy. We're too tired. We need a break — we'll start next week. At the same time, we're bombarded by messages from people who are all about fitness — influencers with seemingly perfect bodies and a healthy glow, who convince us that we too can get into shape. It's a habit that many of us try to cultivate — yet often seem to hit a wall. On this episode, we look at the science of fitness, the evolution of cultural messages surrounding exercise, and how we can overcome inertia to start fitting it into our lives. We'll hear about how exercise affects our mood and overall health, different approaches to getting in shape, the real-life struggle of becoming an Instagram fitness influencer, and one couch potato's reluctant journey to getting active.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Taking the Temperature of Climate Science
We hear about the big picture of climate change almost every day — the threats it poses, the effects on our world and lives, the fight to stop it. Across the world, armies of researchers are contributing pieces to that big picture narrative every day. They often travel long distances and brave the elements to collect information, one small data point at a time. How do Antarctic penguins fare when warming temperatures bring changing conditions to a part of the continent? How do we really know what Earth's climate was like in the past, and how it compares to today? What's it like to spend months living on an old oil drilling ship, in search of tiny ancient fossils? On this episode, we go behind the headlines to spend time with scientists on the front lines of climate research. We'll hear how they're collecting data, what they're learning, and what keeps them motivated. We hear about climate change almost every day — the threats it poses, the fight to stop it.

Call Me — Maybe? 50 Years Since the First Cell Phone Call
On April 3, 1973, an engineer named Martin Cooper stood nervously along a busy midtown Manhattan street, about to make a phone call. It was a call that would change life as we know it: The first cell phone call ever. The phone Cooper used that day — a prototype — was a bulky, 2-pound monster that looked a bit like a shoe with an antenna sticking out of the top. In the half-a-century since, this technology has changed more about the way we communicate and connect than Cooper could've ever imagined. On this episode, we mark the 50th anniversary of the first cell call with an exploration of the past, present, and future of mobile communications. We hear about Cooper's work on this world-altering invention, one community's fight against the 5G revolution, and why satellite phones are making a comeback in a big way.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Bringing Physics from Theory to Practice
Science is all about observing the world. But how do you study something you can't see, smell, or hear — like the tiniest particles all around us? How do you test a new energy source when it doesn't really exist yet? These are the challenges that the world of physics often faces. You can come up with theories, using modeling and calculations, and devise some kind of experiment on paper to investigate things. But then you have to translate those ideas into tangible, real-world experiments, which is often incredibly challenging. On this episode, we peek behind the curtain of multimillion-dollar physics experiments that are changing the way we understand our world — and hear about some of the big challenges they face. We dig into the origins of the James Webb Space Telescope, talk with xkcd cartoonist Randall Munroe about some of his more outlandish — and complicated — physics calculations, and hear from accelerator physicist Suzie Sheehy about the physics experiments that changed the world.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Black Health: Finding Solutions to Disparities
Health disparities between Black and white Americans run deep in the U.S. Black people are more likely to suffer from chronic conditions like diabetes, hypertension, heart disease, or asthma, and their life expectancy is shorter than that of their white peers. The causes for these inequities are far-reaching and include bias and systemic racism in health care and medical treatments, lack of access to care, and economic differences. Advocates, researchers, and health systems have been looking for ways to address these issues — chipping away at different aspects of the problem. On this episode, we'll look at several different solutions — and meet the people who are pushing for more equitable health care for all.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

The Therapist in your Pocket
Finding the right therapist — or, sometimes, any therapist — can be a grueling process. Someone with the right expertise, who is still taking new clients, lives in your area, who accepts your insurance, or whose services you can afford. Over the past few years, online therapy platforms like BetterHelp and Talkspace have seen an explosion in popularity. They promise easy access — anytime you need it — and affordability. Major changes are happening in the field of mental health, as more people turn to online services — not just for counseling, but for diagnosis and prescriptions. How good are these platforms really — for clients and for therapists? And what are the larger issues they raise about the field as a whole? On this episode, we look at the rise of online mental health services. We hear stories about working for one of these apps, what clients like or dislike about them, and the unregulated world of online ADHD diagnosis.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Transformative Power of Awe
It's the goosebumps you get at the crescendo of your favorite song; the stupefying wonder that comes with witnessing a birth or a death; the astonishing mystery we feel when gazing at the vast night sky. This is awe — a complex, often overwhelming emotion that can elicit everything from pleasure and connectedness to a crawling sense of uncertainty. Moments of awe can create unforgettable memories — and they can have a lasting impact on our minds and the way we interact with others. One of the leading scientists studying awe is Dacher Keltner, a University of California, Berkeley psychologist, who's dedicated the past 15 years to investigating the origins and effects of this emotion. On this episode, we talk with Keltner about his new book "Awe: The New Science of Everyday Wonder and How it Can Transform Your Life." He discusses his own, very personal experience of awe amid profound grief, the ability of awe to transform our experience of the world, and how we can cultivate awe on a daily basis. We also hear from listeners about their experiences of awe, and listen back to a story about how voyages to space change the way astronauts perceive life, their relationships, and Earth as a whole.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
