6 doctors swallowed Lego heads for science. Here's what came out

As an emergency physician at Western Health, in Melbourne, Australia, Dr. Andy Tagg says he meets a lot of anxious parents whose children have swallowed Lego pieces. Much like Andy so many years ago, the vast majority of kids simply pass the object through their stool within a day or so. But Andy and five other pediatricians wondered, is there a way to give parents extra reassurance ... through science?

Time is so much weirder than it seems

Time is a concept so central to our daily lives. Yet, the closer scientists look at it, the more it seems to fall apart. Time ticks by differently at sea level than it does on a mountaintop. The universe's expansion slows time's passage. "And some scientists think time might not even be 'real' — or at least not fundamental," says NPR science correspondent Geoff Brumfiel. Geoff joined Short Wave Scientist in Residence Regina G. Barber to bend our brains with his learnings about the true nature of time. Along the way, we visit the atomic clocks at the National Institute of Standards and Technology, consider distant exploding stars and parse the remains of subatomic collisions.

Humans want to make everything better — but sometimes different is just as good

Are humans ever satisfied? Two social psychologists, Ethan Ludwin-Peery and Adam Mastroianni, fell down a research rabbit hole accidentally answering a version of this very question. After conducting several studies, the pair found that when asked how things could be different, people tend to give one kind of answer, regardless of how the question is asked or how good life felt when they were asked. Short Wave's Scientist in Residence Regina G. Barber digs into the research—and how it might reveal a fundamental law of psychology about human satisfaction.

Redlining's Ripple Effects Go Beyond Humans

When Dr. Chloé Schmidt was a PhD student in Winnepeg, Canada, she was studying wildlife in urban areas. She and her advisor Dr. Colin Garroway came across a 2020 paper that posed a hypothesis: If the echos of systemic racism affect the human residents of neighborhoods and cities, then it should affect the wildlife as well. Short Wave Scientist in Residence Regina G. Barber talks to Chloé and Colin about their findings of how redlining and biodiversity are intertwined.

What do astronauts do all day? We talked to one 250 miles above Earth to find out

Speaking to Short Wave from about 250 miles above the Earth, Josh Cassada outlined his typical day at work: "Today, I actually started out by taking my own blood," he said. The astronauts aboard the International Space Station are themselves research subjects, as well as conductors of all sorts of science experiments: Gardening in microgravity, trapping frigid atoms, examining neutron stars. Then, there's the joy of walks into the yawning void of space. Speaking from orbit, Cassada told fellow physicist and Short Wave Scientist in Residence Regina G. Barber about research aboard the station, what it takes to keep the ISS going and which countries' astronauts make the best food.

A Step Closer To Nuclear Fusion Energy

On Dec. 5 at 1 o'clock in the morning local time, researchers at the Lawrence Livermore National Laboratory in California used lasers to zap a tiny pellet of hydrogen fuel. The lasers hit their target with 2.05 megajoules of energy, and the pellet released roughly 3.15 megajoules. It's a major milestone, and one that the field of fusion science has struggled to reach for more than half a century: producing a fusion reaction that generates more energy than it consumes. While progress, the technology is still a ways off from its promise to produce energy without creating greenhouse gases. Today on the show, Regina G. Barber brings us two NPR stories that explain what this experiment showed and what else needs to happen to make fusion a practical energy source.

DART: The Impacts Of Slamming A Spacecraft Into An Asteroid

If an asteroid were hurling through space, making a beeline straight to Earth, how would humans prevent it from doing what it did to the dinosaurs? Would we bomb it? Would we shoot lasers at it like a scene from Hollywood's latest sci-fi flick? Well, the folks at NASA have designed and tested a theory.

What Makes Hawaii's Erupting Volcanoes Special

Just after Thanksgiving, for the first time in almost 40 years, Hawaii's Mauna Loa volcano erupted. It's one of several ongoing eruptions – including Kilauea, also on Hawaii, and Indonesia's Mount Semeru. At just over half the size of the big island of Hawaii, Mauna Loa is the world's biggest active volcano.

In the hunt for a male contraceptive, scientists look to stop sperm in their tracks

For decades birth control research focused on women. Now there's a new push to develop gels, pills or other products that could keep men from getting their partners pregnant.

Corey Gray Is Picking Up Cosmic Vibrations

A pivotal week in Corey Gray's life began with a powwow in Alberta and culminated with a piece of history: the first-ever detection of gravitational waves from the collision of two neutron stars. Corey was on the graveyard shift at LIGO, the Laser Interferometer Gravitational Observatory in Hanford, Washington, when the historic signal came. Corey tells Short Wave Scientist in Residence Regina G. Barber about the discovery, the "Gravitational Wave Grass Dance Special" that preceded it, and how he got his Blackfoot name.

New Discoveries In Underwater Plant Sex

Plants living underwater can't count on pollinating insects to get it on. The prevailing theory has been that pollen moves underwater simply by floating around in water currents. But a team of researchers co-led by Dr. Vivianne Solís-Weiss, have discovered a helper organism pitching in to pollinate seagrasses: marine worms. In today's episode, Vivianne tells Short Wave Scientist in Residence Regina G. Barber how she happened to catch these worms, called polychaetes, in the act of pollinating seagrass flowers underwater, and how the discovery is shedding new light on evolution in the oceans.
