The Promise and Future of Psychedelics Research

The Pulse ·

2024/08/16

Interest in using psychedelics for mental health treatments has taken off in recent years — but the field was just dealt a major blow on August 9, when the Food and Drug Administration rejected a bid by Lykos Therapeutics to approve the first-ever MDMA treatment for PTSD. The agency said it needed more research to show that the drug was safe and effective. The decision means that an active research community that has formed over the last few decades will likely continue as it started — more

The Big Chill and the Future of Refrigeration

The Pulse ·

2024/08/09

We've only been able to harness the cold for our benefit for a little over 100 years, but innovations like refrigeration and air conditioning have completely transformed the way we live and eat.A massive cold chain makes it possible to buy salmon from Alaska, grapes from Chile, and cheese from Italy; to have sushi in Kansas and ice cream in the summer. Air conditioning allows us to function and to be comfortable during the hot summer months. But it all comes at a cost, and not just financially

Asking for Help

The Pulse ·

2024/08/02

Asking for help is hard. It can make us feel vulnerable, like we're sharing too much or admitting weakness. It can also stoke fears about our relationships and sense of self-worth — am I being a burden? Will they resent me later? What if they say no?And yet, the ability to ask for help is an important life skill that not only helps us survive, but can make us feel loved, supported and connected.On this episode, we hear stories about what happens when different people ask for help — from the

Sharks — From Fear to Fascination

The Pulse ·

2024/07/26

Before dinosaurs, before trees — even before Saturn had its rings – there were sharks. The fierce predators have been swimming in our oceans for hundreds of millions of years, standing the test of time as they survived all five of Earth's mass extinction events.Now, though, many of them face unprecedented threats, from overfishing to climate change. But there's a movement underway to protect sharks — and to change their public image, which suffered after the classic movie Jaws.On this episode, we

How Money Shapes Medicine

The Pulse ·

2024/07/19

Health care is a billion dollar industry in the U.S. — one of the biggest in the country. The business aspect of medicine is an invisible force in the doctor's office that shapes treatment decisions and care. As patients, financial worries can affect whether we go to the doctor in the first place, make us suspicious of expensive procedures, or even cause us to turn down necessary care. And patients aren't the only ones worrying about money — on the provider side, everyone from doctors to hospitals

Unearthing the Secrets of Volcanoes and Rocks

2024/07/12

It's easy to forget that the earth below us is always changing and shifting — but sometimes, we get a dramatic demonstration of exactly that, like with the recent eruptions of a volcano in Iceland.Volcanoes can devastate and destroy, but they're also an integral part of our planet's history and even evolution. And the same goes for the rocks beneath our feet — they're ancient artifacts, historical records, time capsules filled with clues about Earth's past and its future.On this episode, we read

Degrees of Freedom

2024/07/05

On this rebroadcast of The Pulse: Freedom sounds great as an idea. Who doesn't want to be free to do what they want? But when you take a closer look, freedom becomes more complicated. What does it really mean to be free — and how free can we be? On this encore episode, we'll look at freedom from different perspectives. We'll talk with a neuroscientist who says we evolved to have free will — even though it can sometimes feel like our brains are just following a bunch of preset options. And we'll hear

How Amazon Revolutionized Shopping and Changed the World

The Pulse ·

2024/06/28

Amazon caught the wave of the early internet at a time when very few people even understood what the internet was. Launched in a garage 30 years ago, the company has grown from its humble beginnings to a global powerhouse that has expanded into all kinds of sectors, everything from cloud computing to health care. Founder Jeff Bezos wanted Amazon to become a daily habit for consumers — and for many people, it's become just that. And even if you're not ordering anything today, chances are, you are

Making Faces

2024/06/21

Imagine looking at a crowd of people, and they either all look vaguely familiar, or like complete strangers. It doesn't matter if this is a group of classmates or colleagues, or people you have never met before. That's a daily experience for people who have a condition called face blindness — who can't recognize people based on their faces. Face recognition takes up a lot of real estate in our brains, and for good reason; recognizing people allows us to form relationships, tell friend from foe, and

The DIY Medicine Movement

2024/06/14

DIY culture is all about empowerment — teaching yourself new skills to do things on your own, like retiling your bathroom or fixing a leaky faucet. But what happens when the DIY approach extends to something as complicated and potentially dangerous as medicine?On this episode, we take a look at the growing number of patients who are taking health care into their own hands — experimenting with DIY treatments ranging from brain stimulation to homemade wound ointments.

The Search for Modern Masculinity

Competent. Capable. Strong. Stoic. Provider. Protector. Leader. Patriarch. These are the kinds of words that we've long associated with masculinity and manhood — but in recent decades, ideas of what it means to be a man have undergone drastic changes.As women have gained ground in education and careers, politics and culture, the role of men has shifted. They're no longer automatically assumed to be the main breadwinners, the decision-makers or leaders. And a lot of the "masculine" attributes that

When it comes to science, it's often the flashiest stories that grab headlines — the cancer breakthroughs, the tech innovations, the discoveries of new species or distant stars. But there's also plenty of science that, while it may not make a huge splash, is quietly changing the way we live.On this episode, The Pulse celebrates its 10-year anniversary with a special live show that turns the spotlight on the science changing our everyday lives.

How Art and Science Intersect

2024/05/24

On this rebroadcast of The Pulse - We often think of art and science as existing in different — even opposite — spheres. One revolves around creativity and imagination; the other around observable facts and data — and never the twain shall meet.But really, art and science aren't as far apart as we might think. For centuries, artists have drawn on the natural sciences, and the wonders of the natural world, as inspiration for some of our most celebrated works.On this episode, we explore the hidden

When Being 'Gifted' No Longer Feels Like a Gift

2024/05/17

When psychologist Lewis Terman launched his decades-long study of high-IQ children in 1921, he had a specific goal in mind: to prove that "gifted" people were born leaders, and superior in just about every way. Although his theory didn't pan out, Terman did kick off national interest in identifying and cultivating intellectually gifted children.Just over a century later, experts in science, education, and psychology are grappling with questions about how we define giftedness, who qualifies as

We hear all the time about the joys of motherhood — the incomparable sense of love, the magic of watching your kids discover the world, the pride and fulfillment of seeing them grow. But motherhood can also be a grind. These days, moms are expected not only to care for their kids, but to grow their careers — all while juggling housework, swimming lessons, doctor's appointments, play groups, the family calendar, and more.On this episode, we take a look at the experience of modern motherhood — the

Rediscovering America's War on Bad Posture

In January 1995, the New York Times Magazine published a bombshell story with the headline: "THE GREAT IVY LEAGUE NUDE POSTURE PHOTO SCANDAL." The article revealed that, from the 1940s through the 1960s, elite colleges had taken naked photos of thousands of freshmen, including future luminaries like George Bush, Bob Woodward, Meryl Streep, and Hillary Rodham. For years, the schools had teemed with anxious, tawdry rumors about both the purpose and fate of the photos. Who had them? What were they

Breaking the Silence on Medical Mistakes

The Pulse ·

2024/04/26

When medical mistakes happen, patients and their families often find themselves at a loss trying to figure out exactly what went wrong. Something bad happened. And then, communication drops; there's no real explanation, and no apology. Suddenly, everybody seems on guard. Health care providers can often feel bound by an imposed cone of silence that's designed to protect them and their institution, but makes it impossible to fully face up to their mistake, or have open conversations about preventing

Living Greener — One Decision at a Time

Every day, we hear about countless environmental threats — from air pollution and microplastics, to deforestation and global warming. And a lot of us feel overwhelmed by the scale of these problems, and helpless to enact global big-picture solutions. But small, everyday decisions matter too — and they add up. How you do your laundry, how warm or cool you keep your home, what you eat for lunch, what kinds of products you buy and or how you sort your trash — all of them have the potential to make a
