A Fatal Virus With Pandemic Potential

Short Wave ·

2023/02/02

The Nipah virus is on the World Health Organization's short list of diseases that have pandemic potential and therefore pose the greatest public health risk. With a fatality rate at about 70%, it is one of the most deadly respiratory diseases health officials have ever seen. But as regular outbreaks began in the early 2000s in Bangladesh, researchers were left scratching their heads. Initially, the cause of the outbreaks was unknown to them. But once they identified the virus, a second, urgent

The Ancient Night Sky And The Earliest Astronomers

Short Wave ·

2023/02/01

Moiya McTier says the night sky has been fueling humans' stories about the universe for a very long time, and informing how they explain the natural world. In fact, Moiya sees astronomy and folklore as two sides of the same coin. "To me, science is any rigorous attempt at understanding and explaining the world around you," she explained to Short Wave's Aaron Scott. "You can see that they knew enough about the world around them to predict eclipses, to predict annual floods in Egypt, for example. I

Can you teach a computer common sense?

2023/01/31

Over the past decade, AI has moved right into our houses - onto our phones and smart speakers - and grown in sophistication. But many AI systems lack something we humans take for granted: common sense. In this episode Emily talks to MacArthur Fellowship-winner Yejin Choi, one of the leading thinkers on natural language processing, about how she's teaching machines to make inferences about the real world.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Gas Stoves: Sorting Fact From Fiction

Short Wave ·

2023/01/30

Gas stoves are found in around 40% of homes in the United States, and they've been getting a lot of attention lately. A recent interview with Richard Trumka, the commissioner of the U.S. Consumer Product Safety Commission (CPSC), quickly became fodder for outrage, viral disinformation and political fundraising after he proposed regulating the appliance. The proposal stems from a growing body of research suggesting gas stoves are unhealthy — especially for those with asthma, chronic obstructive

6 Doctors Swallow Lego Heads ... What Comes Out?

2023/01/26

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? So the doctors devised an experiment.

Our Perception Of Time Shapes The Way We Think About...

Most people are focused on the present: today, tomorrow, maybe next year. Fixing your flat tire is more pressing than figuring out if you should buy an electric car. Living by the beach is a lot more fun than figuring out when your house might be flooded by rising sea levels.That basic human relationship with time makes climate change a tricky problem.Host Emily Kwong talks to climate correspondent Rebecca Hersher about how our obsession with the present can be harnessed to tackle our biggest

Fossil CSI: Cracking The Case Of An Ancient Reptile...

Short Wave ·

2023/01/23

This mystery begins in 1952, in the Nevada desert, when a self-taught geologist came across the skeleton of a massive creature that looked like a cross between a whale and a crocodile. It turned out to be just the beginning. Ichthyosaurs were bus-sized marine reptiles that lived during the age of dinosaurs, when this area of Nevada was underwater. Yet paleontologists found few other animals here, which raised the questions: Why were there so many adult ichthyosaurs, and almost nothing else? What

New Tech Targets Epilepsy With Lasers, Robots

About three million people in the United States have epilepsy, including about a million who can't rely on medication to control their seizures. For years, those patients had very limited options. But now, in 2023, advancements in diagnosing and treating epilepsy are showing great promise for many patients, even those who had been told there was nothing that could be done. Using precise lasers, microelectronic arrays and robot surgeons, doctors and researchers have begun to think differently about

What Cities Should Learn From California's Flooding

2023/01/19

Winter storms have flooded parts of California, broken levees and forced thousands to evacuate. Climate change is altering the historic weather patterns that infrastructure like reservoirs and waterways were built to accommodate. Urban planners and engineers are rethinking underlying assumptions baked into buildings and water systems in order to adapt to the changing climate.

Time Is So Much Weirder Than It Seems

2023/01/18

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.

A Course Correction In Managing Drying Rivers

Historic drought in the west and water diversion for human use are causing stretches of the Colorado and Mississippi rivers to run dry.

Things Could Be Better

2023/01/13

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.

Behold! The Mysterious Ice Worm

Inside the mountaintop glaciers of the Pacific Northwest lives a mysterious, and often, overlooked creature. They're small, black, thread-like worms that wiggle through snow and ice. That's right, ice worms! Little is known about them. But one thing scientists are sure of? They can't really handle freezing temperatures.

How Glaciers Move

There's always a moment of intense isolation when Jessica Mejía gets dropped off on the Greenland ice sheet for a multi-week research stint. "You know you're very much alone," said Jessica, a postdoctoral researcher in glaciology at the University of Buffalo. Glaciers such as those that cover Greenland are melting due to climate change, causing sea levels to rise. That we know. But these glaciers are also moving. What we don't know is just how these two processes – melting and movement – interact

Zircon: The Keeper Of Earth's Time

The mineral zircon is the oldest known piece of Earth existing on the surface today. The oldest bits date back as far as 4.37 billion years — not too far from the age of Earth itself at about 4.5 billion years old. And, unlike other minerals, zircon is hard to get rid of. This resilience enables scientists to use zircon to determine when major geological events on Earth happened.

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.

An Atmospheric River Runs Through It

2023/01/06

From space, it looks almost elegant: a narrow plume cascading off the Pacific Ocean, spilling gently over the California coast. But from the ground, it looks like trouble: flash flooding, landslides and power outages. California is enduring the effects of an atmospheric river, a meteorological phenomenon where converging air systems funnel wet air into a long, riverine flow that dumps large amounts of rain when it makes landfall. "Atmospheric rivers can transport volumes of water many times that of
