Science, Spoken

A year ago, while on a tourist visit to Latvia, Sharon Bard was awoken at 4 am by a buzzing alert from her phone. It was an email from a friend who’d been checking on her home in Santa Rosa, California. Given the alarming news, the email's phrasing was rather gentle: A fire had broken out in the area, officials had ordered evacuations, and Bard’s country house at the end of a road might be affecte...

“The Falcon has landed.” As SpaceX declared victory on its live webcast, cheers erupted on a southern California hilltop, where a group of watchers had gathered to witness the company’s latest rocket launch (and landing). SpaceX had just achieved another first: touching down a rocket on California soil. Until now, the company’s West Coast landings had all taken place on the deck of the company’s d...

When Kim Schrier campaigns in central Washington farm towns, she talks about protecting health care, reforming immigration laws, and the harmful effects of new White House tariffs on the region’s hay, cherry, and apple growers. But she says she also brings up climate change and what it means for local businesses. “Our farmers have a lot of evidence that the climate is changing,” says Schrier, the...

I can imagine the meeting: A dozen engineers are gathered around a conference table to discuss automobile safety. How can we protect people during a car crash? We have already added seat belts and crumple zones to cars. Is there anything else we can include? One attendee reluctantly raises their hand with a suggestion: "How about we add an explosive in the steering wheel?" Brilliant. That's exactl...

The bees, as you've probably heard, are dying, in massive numbers. Termed Colony Collapse Disorder, the die-off counts among its causes a parasite aptly named Varroa destructor. A flat, button-shaped, eight-legged critter no more than 2 millimeters long, Varroa mites invade honeybee hives around the world in droves, latch onto their inhabitants, and feed on their tissues, transmitting devastating...

The temperature in Waco, Texas was approaching 83 degrees last Thursday when Mia Mattioli arrived in search of Naegleria fowleri, a brain-eating, warm-water-loving amoeba that kills almost every person it infects. An environmental engineer at the Centers for Disease Control and Prevention, Mattioli spent the day at BSR Surf Resort, a local water park, filling fifty-liter jugs with samples from the...

Two weeks ago, Hurricane Florence slammed into the Carolinas, unleashing six months of rain in a matter of hours. In inland Cumberland County, the Cape Fear River rose 40 inches, inundating Fayetteville with the worst flooding the city has seen since 1945. But as the waters receded and citizens returned to their ruined homes, a new plague was just beginning to descend. Learn more about your ad cho...

The laser is a tool of many talents, as the Nobel committee well knows. On Tuesday morning in Stockholm, its members announced the year’s physics prize and rattled off a short list of the technologies it has made possible: barcodes, eye surgery, cancer treatment, welding, cutting materials more precisely than a scalpel. They failed to acknowledge the whimsy it has brought cat owners, although one...

Robots are the most powerful blank slate humans have ever created. Want a helpful robot? No problem. Want a mean one? Sure, if that’s what you’re into. A robot is a mirror held up not just to its creator, but to our whole species: What we make of the machine reflects what we are. That also means we have the very real opportunity to screw up robots by infusing them with exaggerated, overly simplifi...

David Hughes leans back in his office in a standard-issue professorship chair as Penn State students in a plaza behind him shuffle toward classes. Between us on his desk—on either side of a paper cup of black coffee—are two trays of dead ants stuck through with pins. Some cling to leaves, others curl up around sticks, frozen in their tiny death postures like the now-fossilized humans who couldn’t...

Jake Misch’s family has been growing corn in the sandy soils of northwestern Indiana for four generations. Like other farmers in the area, the Misches spray their fields with a nitrogen-rich fertilizer once in the spring when the seeds are planted, and once later in the year, when the corn is going through its growth spurt.

This story originally appeared on Reveal and is part of the Climate Desk collaboration. William Whitt suffered violent diarrhea for days. But once he began vomiting blood, he knew it was time to rush to the hospital. His body swelled up so much that his wife thought he looked like the Michelin Man, and on the inside, his intestines were inflamed and bleeding. For four days last spring, doctors str...

There was a time many years ago when cars guzzled gas like beer, teenagers raced them on Friday nights, and Detroit automakers boasted about their vehicles' ever-increasing horsepower and speed. Since then, cars have become safer, cleaner and more efficient, mostly as a result of tougher standards from Washington. Learn more about your ad choices. Visit podcastchoices.com/adchoices

In 2003, San Francisco set the lofty objective of getting to zero waste by 2020. By that timeline, the city should soon be performing a ceremonial burial for the last pair of broken headphones and closing down its moldering landfills. But with the deadline approaching, the city has sent that goal itself to the garbage heap. Earlier this month, as part of the Global Climate Action Summit, Mayor Lon...

On Thursday, Darpa gathered roboticists in the Louisville Mega Cavern, in Kentucky, and gave them a mission: Design robots to navigate a grueling subterranean course of tunnels and caves, some of the most unforgiving environments on Earth. They’re calling it the Subterranean Challenge, but you may as well call it the Death to All Robots Challenge. This event, which will begin next year, is a funda...

While Americans still wrangle their overgrown lawns by pushing or riding a lawnmower, many Europeans have handed off that responsibility to robots. These beefy, Roomba-like mowers loop their way around a yard, keeping grass trim and neat. To many of their users, the bots are endearing. Their owners give them names or cover them in decals of ladybugs or bumblebees. But the sentimentality only goes...

In the summer of 2017, Michael Parsons found the urban rat haven of his dreams: A Waste Management transfer station—aka a literal trash heap, aka rat paradise—in Brooklyn, New York. For nearly two years, the behavioral ecologist and visiting scholar at Fordham University had been searching for a place to observe the city-dwelling rodents in their natural habitat. Trouble was, he needed to not only...

The Moon is a pretty barren place. Sure, there are a few buggies, some golf balls, a flag, urine bags, a family photo. But it’s mostly empty. If a company called ispace has its way, though, Earth’s closest space neighbor will soon(ish) be the site of a bustling, industrial city full of workers and tourists. Moon Valley, the dreamers call it. Learn more about your ad choices. Visit podcastchoices.c...

You’ve heard that social media is screwing with your brain. Maybe you even read about it on social media. (So meta; so messed up.) The neurochemical culprit, dopamine, spikes when you like and get liked, share and are shared. You’ve probably also heard scientists compare the affliction to drug or alcohol addiction. That’s fair. The same part of the brain lights up. Scroll, scroll, scroll. It’s a p...

Jellyfish float through the ocean like drones of the sea. Their simple nature makes them a natural muse for robot engineers building devices that can squeeze through tight spaces, check the ocean’s health, and eventually, explore the human body. This week, a team at Florida Atlantic University unveiled a new eight-inch wide robo-jellyfish built to monitor marine life and harsh underwater habitats....

Rejoice! The machines won’t be taking over the world anytime soon, because doing the most basic of tasks still confounds them. I mean, have you thought lately about how hard it is to pick a ripe bell pepper? Fine, me neither. But researchers in Israel and Europe certainly have. They're developing a robot called Sweeper that can autonomously roam a greenhouse, eyeballing peppers to determine if the...

In 2003, scientists at London’s Imperial College hatched a somewhat out-there idea. They wanted to deal with the increasingly pesticide-resistant mosquitoes that were killing half a million people a year by spreading malaria in sub-Saharan Africa. What biologists Austin Burt and Andrea Crisanti proposed was nothing short of hacking the laws of heredity. Learn more about your ad choices. Visit podc...

After the storm comes the flood. Hurricane Florence poured 8 trillion gallons of rain onto North Carolina, and now the landscape between the Cape Fear River and the barrier islands of the Carolinas is a waterworld. Because ecological disasters happen in irony loops, that means long-recognized hazards have now become add-on catastrophes. First the floodwaters found thousands of literal cesspools co...

The transmission electron microscope was designed to break records. Using its beam of electrons, scientists have glimpsed many types of viruses for the first time. They’ve used it to study parts of biological cells like ribosomes and mitochondria. You can see individual atoms with it. But experts have recently unlocked new potential for the machine. “It’s been a very dramatic and sudden shift,” sa...

Last weekend, the Delta II rocket—for 30 years a regular fixture on launchpads in the United States—lifted off for the final time. The vehicle, built by the United Launch Alliance, had long carried the title of the most reliable rocket in service. With a record 153 successful launches out of 155 flights, the 125-foot-tall monolith, with its sporty teal-and-white paint scheme, is now officially a f...
