Are We On The Brink Of A Nuclear Fusion Breakthrough?

Short Wave ·

2024/03/15

Nuclear fusion could one day change the world by producing energy at lower costs than we generate it now — without greenhouse gas emissions or long-term nuclear waste. If we can get it to work. People have been promising nuclear fusion as a new, clean source of power for decades without much tangible success. But lately, billions of dollars from venture capitalists and tech entrepreneurs have flowed into the field. Science correspondent Geoff Brumfiel shares his reporting on some of the companies

2024/03/13

"Long COVID has affected every part of my life," said Virginia resident Rachel Beale said at a recent Senate hearing. "I wake up every day feeling tired, nauseous and dizzy. I immediately start planning when I can lay down again." Beale is far from alone. Many of her experiences have been echoed by others dealing with long COVID. It's a constellation of debilitating symptoms that range from brain fog and intense physical fatigue to depression and anxiety. But there's new, promising research that

2024/03/11

Coming down from the buzz of the Oscars, we're taking a look at Christopher Nolan's award-winning film 'Oppenheimer.' It chronicles the life and legacy of J. Robert Oppenheimer, the first director of Los Alamos National Laboratory and the so-called "Father of the Atomic Bomb." The movie does not shy away from science — and neither do we. We talked to current scientists at Los Alamos about the past and present science of nuclear weapons like the atomic bomb.Read more about the Manhattan Project.Have

2024/03/08

Neuroscientist Nathan Sawtell has spent a lot of time studying the electric elephantnose fish. These fish send and decipher weak electric signals, which Sawtell hopes will eventually help neuroscientists better understand how the brain filters sensory information about the outside world. As Sawtell has studied these electric critters, he's had a lingering question: why do they always seem to organize themselves in a particular orientation. At first, he couldn't figure out why, but a new study

The Recent Glitch Threatening Voyager 1

2024/03/06

The Voyager 1 space probe is the farthest human-made object in space. It launched in 1977 with a golden record on board that carried assorted sounds of our home planet: greetings in many different languages, dogs barking, and the sound of two people kissing, to name but a few examples. The idea with this record was that someday, Voyager 1 might be our emissary to alien life – an audible time capsule of Earth's beings. Since its launch, it also managed to complete missions to Jupiter and Saturn. In

2024/03/04

Recently, the US Food and Drug Administration approved a first-of-its-kind cancer therapy to treat aggresive forms of skin cancer. It has us thinking of the long history of cancer. One of the first recorded mentions of cancer appears in an ancient Egyptian text from around 3000 B.C. And although we now know much more about how cancer begins — as a series of mutations in someone's DNA — it's a disease people are still grappling with how to cure cancers today.

The sci-fi film Dune: Part Two is out in theaters now. The movie takes place on the harsh desert planet, Arrakis, where water is scarce and giant, killer sandworms lurk just beneath the surface. But what do planetary scientists and biologists think about the science of these worms, Arrakis and our other favorite sci-fi planets? Today on the show, Regina G. Barber talks to biologist (and Star Trek consultant!) Mohamed Noor and planetary scientist Michael Wong about Dune, habitable planets and how to

2024/02/28

According to the United Nations, about ten percent of the world is undernourished. It's a daunting statistic — unless your name is Hannah Ritchie. She's the data scientist behind the new book Not the End of the World: How We Can Be the First Generation to Build a Sustainable Planet. It's a seriously big thought experiment: How do we feed everyone on Earth sustainably? And because it's just as much an economically pressing question as it is a scientific one, Darian Woods of The Indicator from Planet

An Alabama Supreme Court ruling that frozen embryos can be considered "extrauterine children" under state law has major implications for how in vitro fertilization, commonly called IVF, is performed. Since the first successful in vitro fertilization pregnancy and live birth in 1978, nearly half a million babies have been born using IVF in the United States. Reproductive endocrinologist Amanda Adeleye explains the science behind IVF, the barriers to accessing it and her concerns about fertility

In the green tree canopies of forested areas in Myanmar, you might wake up to the sounds of gibbons singing love songs. Gibbons start their day with passionate duets and, though these love songs may sound a little different than the ones in your playlists, they just helped researchers figure out that Myanmar has the largest population of an endangered gibbon species on Earth. They're called skywalker gibbons, and until recently, scientists thought there were fewer than 200 of them – all living in

We are at the height of the Sun's activity in its eleven year cycle, known to astronomers as the solar maximum. This means that over the next several months there's going to be a lot of solar activity. It's got us thinking back to 1859. That's when astronomer Richard Carrington was studying the Sun when he witnessed the most intense geomagnetic storm recorded in history. The storm, triggered by a giant solar flare, sent brilliant auroral displays across the globe causing electrical sparking and

The Life And Death Of A Woolly Mammoth

2024/02/19

Lately, paleoecologist Audrey Rowe has been a bit preoccupied with a girl named Elma. That's because Elma is ... a woolly mammoth. And 14,000 years ago, when Elma was alive, her habitat in interior Alaska was rapidly changing. The Ice Age was coming to a close and human hunters were starting early settlements. Which leads to an intriguing question: Who, or what, killed her? In the search for answers, Audrey traces Elma's life and journey through — get this — a single tusk. Today, she shares her

Every year, billions of animals across the globe embark on journeys. They fly, crawl, walk or slither – often across thousands of miles of land or water – to find better food, more agreeable weather or a place to breed. Think monarch butterflies, penguins, wild Pacific salmon. These species are crucial to the world as we know it. But until this week, there has never been an official assessment of the world's migratory animals. So today on the show, correspondent Nate Rott shares the first-ever

Happy Lunar New Year! According to the Chinese lunisolar calendar, the new year began Saturday. For many, like our host Regina G. Barber, this calendar and its cultural holidays can feel completely detached from the Gregorian calendar. Growing up, she associated the former with the Spring Festival and getting money in red envelopes from relatives, and the other with more American traditions. But the Chinese calendar has a deep, centuries-long shared history with the Gregorian calendar. To learn more

At least, that's what a group of researchers at the Okinawa Institute of Science and Technology Graduate University thinks. The team recently published a study in the journal Experimental Biology suggesting that Amphiphrion ocellaris, or clown anemonefish, may be counting. Specifically, the authors think the fish may be looking at the number of vertical white stripes on each other as well as other anemonefish as a way to identify their own species. Not only that — the researchers think that the fish

If you've ever watched part of a professional football game, you've probably seen a tight spiral pass. Those perfect throws where the football leaves the player's hand and neatly spins as it arcs through the air. But those passes? They seem to defy fundamental physics. And for a long time, scientists couldn't figure out exactly why — until experimental atomic physicist Tim Gay cracked the case just a few years ago. His answer comes after two decades of hobby research and more than a couple late

In 1986 the Chernobyl nuclear power plant exploded, releasing radioactive material into northern Ukraine and Belarus. It was the most serious nuclear accident in history. Over one hundred thousand people were evacuated from the surrounding area. But local gray wolves never left — and their population has grown over the years. It's seven times denser than populations in protected lands elsewhere in Belarus. This fact has led scientists to wonder whether the wolves are genetically either resistant or
