Find yourself adrift at sea, surrounded by undrinkable water, and you will parch to death. Find yourself lost in a desert and you will meet the same fate, also surrounded by water, also undrinkable. That’s because, even in the driest of lands, the air is loaded with water molecules—they just won’t do you any good. Devices exist that can pull that water out of the air and convert it into liquid, but they are bulky and use a lot of energy. Learn about your ad choices: dovetail.prx.org/ad-choices...

What happens when you see bad physics in the world? Does it make you angry? Does it make you laugh? Do you have to hold back a tidal wave of "well, actuallys" because of the overwhelming wrongness? Some might feel that way, but I think about it a little differently. In my mind, there are different categories of incorrect physics—and I deal with each one with its own particular strategy.

For 10 years, Andre Igoudala slept terribly. Back in college, the Golden State Warriors forward would play videogames late into the night. Eventually he'd crash, sometimes as late as 4 am, only to wake up a few hours later for practice. Then came class. When he was lucky, he'd squeeze in an afternoon nap. Later that night, it'd be back to videogames—either that or Fresh Prince reruns. Igoudala's brutal sleep habits followed him to the NBA. Learn about your ad choices: dovetail.prx.org/ad-choices...

San Francisco Mayor Ed Lee died in December of 2017; the election to replace him was Tuesday. No one knows who won. Partially that’s because the votes are still trickling in. Mail-in ballots merely had to be postmarked by election day, and as I write the city is reporting 87,000 votes yet to be processed. But that’s not the only roadblock. The other problem is math. See, the San Francisco mayoral election isn’t just another whoever-gets-the-most-votes-wins sort of deal. Learn about your ad choic...

Westworld is a hell of a show, but the sense of dread it elicits is nothing new. Pygmalion sculpted a woman who came to life. Same goes with the Golem, only with mud. The amalgamated Frankenstein jolted awake to get all murderous. Humans creating life in their own image is a cornerstone of the realm of fiction. And until recently, they’ve stayed there. But today, ever-sophisticated robots are graduating from Disneyland-style animatronics into increasingly realistic, intelligent beings. Learn abo...

Today is the first day of the rest of your (storm-tossed, wind-swept, blacked-out, hot, humid) life. Which is to say, June 1 is the official start of the 2018 Atlantic hurricane season. According to most forecasts—at least 26 groups issue them, including the National Oceanic and Atmospheric Administration and Colorado State University—it’s going to be pretty average.

Consider the following physics problem. An object with a mass of 1 kg and a velocity of 1 m/s in the x-direction has a net force of 1 Newton pushing on it (also in the x-direction). What will the velocity of the object be after 1 second? (Yes, I am using simple numbers—because the numbers aren't the point.) Let's solve this simple problem two different ways. For the first method, I will use Newton's Second Law. Learn about your ad choices: dovetail.prx.org/ad-choices...

The bets on liquid biopsy keep getting bigger. Last month, Silicon Valley unicorn Grail Inc. raised a third round of financing to develop its blood-based tests for early cancer detection. That brings its total up to $1.5 billion since 2016, putting it among the top three most heavily funded private biotech companies in the US. While investors might be bullish on the risky venture, many oncologists have been more skeptical about how well Grail’s technique might work. Learn about your ad choices: ...

Bijunath Patla’s experiment sounds like a real bore: Gather 12 of the most accurate clocks around the world, and watch them tick. It’s like a physicist’s version of watching paint dry. Patla’s team, based at the National Institute of Standards and Technology in Boulder, Colorado, began monitoring the clocks on November 11, 1999. And they’ve kept watching for some 4.5 billion seconds—over 14 years. But their patience paid off. Learn about your ad choices: dovetail.prx.org/ad-choices...

The Cray-1 supercomputer, the world’s fastest back in the 1970s, does not look like a supercomputer. It looks like a mod version of that carnival ride The Round Up, the one where you stand, strapped in, as it dizzies you up. It’s surrounded by a padded bench that conceals its power supplies, like a cake donut, if the hole was capable of providing insights about nuclear weapons. After Seymour Cray first built this computer, he gave Los Alamos National Laboratory a six-month free trial. Learn abou...

Over the past two and half centuries, scientists envisioning the origin of planetary systems (including our own) have focused on a specific scene: a spinning disk around a newborn star, sculpting planets out of gas and dust like clay on a potter’s wheel. But as for testing the idea, by actually spotting an exoplanet coalesce from swirling matter? No luck yet. Learn about your ad choices: dovetail.prx.org/ad-choices

Are superheroes real? Maybe. In this recently released video, a firefighter in Latvia catches a man falling past a window. Let me tell you something. I have a fairly reasonable understanding of physics and this catch looks close to being impossible—but it's real. Here is the situation (as far as I can tell). A dude is hanging on a window (actually, the falling human is only rumored to be a male) and then he falls. The firefighters were setting up a proper way to catch him, but it wasn't ready. L...

In the fall of 1987, a young Canadian couple set off from their hometown of Saanich, British Columbia to run a few errands in Seattle. They never made it there; police found their bodies a few days later near Bellingham, Washington. Jay Cook had been beaten and strangled. His girlfriend, Tanya Van Cuylenborg, had been raped and shot in the head. For more than 30 years their families held out hope that police would one day find the killer.

In case you missed it, let me tell you what's going on. This guy has a spaceship near Mars (maybe in orbit) and he is playing around with some modifications to his fusion drive, giving the spaceship super thrust while using very little fuel.

There’s no one way to describe the scent of a beached, rotting whale. See, it really depends on time and space: So long as you’re more than 20 feet away, you don’t smell a thing. But if you’re downwind, the sour stench will just about bowl you over. Its bite sits heavily instead of sharply in your throat. If a zombie wore week-old gym socks, this is what it would smell like. Then consider the time of death. Learn about your ad choices: dovetail.prx.org/ad-choices...

You could be excused, when you first hear Dane Rudy describe his company, for thinking that he wants to use raccoons to send satellites into space. Trash pandas, though, are not the future that Rudy is talking about. He's talking about rockoons—rockets launched from high-altitude balloons. Rockoons trace their trajectory back to the military, like the 1950s Air Force program called Farside. Learn about your ad choices: dovetail.prx.org/ad-choices...

The viral disease Ebola has, as of May 26, killed 25 people in the Democratic Republic of Congo and sickened 31 more. In response, treatment centers have popped up (two of three people who fled one of those centers in the city of Mbandaka have died) and health care workers there are getting a still-experimental vaccine. People who’ve had contact with someone with Ebola, and their contacts, will get the shot, too. Learn about your ad choices: dovetail.prx.org/ad-choices...

Raquel Loreto is a zombie hunter, and a good one. But traipsing through dried leaves in a hot forest in Sanda, at the southern end of Japan, she needed a guide. Just a few months before, she’d been on the internet and come across the work of artist Shigeo Ootak, whose fantastical images depict humans with curious protrusions erupting from their heads. She got in touch, and he invited her to Japan for a hike to find his inspiration. Ootak knew precisely where to look: six feet off the ground. Lea...

The city of Richmond, Calif. juts into the San Francisco Bay like the head of a rhinoceros looking west across the water, toward San Quentin State Prison and the tony towns north of the Golden Gate. It’s a low, industrial town, and 2,900 acres of it is an oil refinery. Chevron is Richmond’s biggest employer, and through taxes contributes about a quarter of the city’s total budget. Chevron is also Richmond’s eternal nemesis. Industrial accidents are an ongoing issue. Learn about your ad choices: ...

If you like science fiction, I can recommend a show for you—The Expanse. It takes place in the not-so-distant future all right here in our own solar system. There are no pew-pew lasers or faster-than-light space travel. When humans are on a spacecraft, they either "float" around or use magnetic boots (except when the spacecraft is accelerating). There are no "inertial dampeners" in The Expanse. Not only that, but it has interesting characters and a compelling plot. I like it. Learn about your ad...

If I told you that flatworms had invaded France, you might say, c'est la vie. A worm is a worm, after all. But then I’d tell you they’re also known as land planarians, and you might think that sounds rather more alien. Then I’d say they’re also called hammerhead flatworms, and you might start getting nervous. Oh, and they grow to a foot long and release secretions from their hammerheads that glue them to their native French prey, the innocent little earthworms. Learn about your ad choices: dovet...

Humans lives their lives trapped in a glass cage of perception. You can only see a limited range of visible light, you can only taste a limited range of tastes, you can only hear a limited range of sounds. Them’s the evolutionary breaks. But machines can kind of leapfrog over the limitations of natural selection. By creating advanced robots, humans have invented a new kind of being, one that can theoretically sense a far greater range of stimuli. Learn about your ad choices: dovetail.prx.org/ad-...

It was stained black, as if someone had ladled tar over its bark. In February, the temperature had dropped below freezing for three hours, killing the limb. The thick leaves had shriveled and fallen away, exposing the green avocados, which then burned in the sun. Learn about your ad choices: dovetail.prx.org/ad-choices...

You like eating, yes? Apples, oranges, berries? For these foods we can thank bees and their extraordinary pollinating powers. Unfortunately, to show our appreciation, humans are killing off bees in staggering numbers—destroying their habitats and poisoning them with pesticides. And at the same time, our population is skyrocketing, which means if we can't get our act together, we have to somehow feed more people with fewer pollinators. Well, living pollinators, that is.

Forget ruby-encrusted swords or diamond-tipped chainsaws. The scanning probe microscope is, quite literally, the sharpest object ever made. Hidden under its bulky silver exterior is a thin metal wire, as fine as a human hair. And at one end, its point tapers to the width of a single atom. Scientists wield the wire not as a weapon, but as an intricate paintbrush—using its needlelike tip to position single atoms on a tiny semiconductor canvas.

The 6-foot-long, 140-pound Chinese giant salamander is a being that defies belief—and seemingly the laws of the physical universe. It’s the largest amphibian on the planet, a gargantuan (though harmless) beast that rests on river-bottoms hoovering up fish. Once it grows big enough, not many critters dare touch it—save for, of course, humans. Particularly the conservationists who are working to save the creature.
