The Creepy-Cute Robot that Picks Peppers With its Face

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 they’re mature enough before sawing them off the plant and placing the produce in a basket.

Here's the Plan to End Malaria With Crispr-Edited Mosquitoes

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 about your ad choices: dovetail.prx.org/ad-choices

First It Was a Hurricane. Then Pig Poop. Now It’s Coal Ash

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 containing the waste of 6 million hogs, and on Friday the waters reached a pool of toxic coal ash. Lea...

New Microscope Shows the Quantum World in Crazy Detail

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,” says physicist David Muller of Cornell University.

The Rocket That Gave Us GPS and the Mars Rovers Retires

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 figure of the past.

The Science Behind Home Disaster Preparedness Kits Is a Disaster

Helicopters got to Wilmington, North Carolina after a day of isolation; Hurricane Florence made landfall there, and the city, with one foot in the Atlantic and the other in the Cape Fear River, soon became an island. Its main roads underwater, Wilmington went without help until boats and choppers reached it with medical supplies, water, and food. But it only took a day. According to the federal government, that’s actually pretty fast. Since the terrorist attacks of Sept. Learn about your ad choi...

Want a Robot to Really Get a Grip? Make It Like Baymax

The octopus is unique among animals in that it can essentially turn itself into liquid, Terminator style. Get yourself a 600-pound octopus and leave it unsupervised and the thing will squeeze itself into a quarter-sized tube and melt its way to freedom. And its manipulation superpowers are legendary—cram it into a jar and it’ll unscrew its way out. So it goes when you’ve got no bones. And loosey-goosey octopuses can teach us a thing or two about robots. Learn about your ad choices: dovetail.prx....

Why Animal Extinction Is Crippling Computer Science

Dodos. Western black rhinoceros. Tasmanian tigers. Bennett's seaweed. The list of extinct animal and plant species goes on and on. It's a tragedy that's only getting worse, we're told, but honestly, I never cared that much. Recently, though, I've found myself sympathizing with those fighting against species extinction. The reason? I'm a computer scientist interested in algorithms. Learn about your ad choices: dovetail.prx.org/ad-choices

SpaceX Will Send Yusaku Maezawa (and Artists!) to the Moon

“I choose to go to the moon.” Those were among the first words uttered on stage Monday night by Yusaku Maezawa, the mysterious passenger whose existence SpaceX CEO Elon Musk had teased on Twitter last week. Maezawa, a Japanese retail entrepreneur and art collector, stood before a small crowd at SpaceX headquarters and announced that he had also secured tickets for several companions on this week-long journey into space: a half-dozen artists that he will later select and invite along.

Astronomers Have Found the Universe's Missing Matter

Astronomers have finally found the last of the missing universe. It’s been hiding since the mid-1990s, when researchers decided to inventory all the “ordinary” matter in the cosmos—stars and planets and gas, anything made out of atomic parts. (This isn’t “dark matter,” which remains a wholly separate enigma.) They had a pretty good idea of how much should be out there, based on theoretical studies of how matter was created during the Big Bang. Learn about your ad choices: dovetail.prx.org/ad-cho...

At the Edge of the World, Facing the End of the World

Writing about climate change is an exercise in managed insanity. The human mind isn’t equipped to parse a crisis—the greatest in the history of our species—of such complexity and urgency and darkness. With record-breaking superstorms ravaging coastlines at a regular clip, it’s hard to feel good about the impact that Homo sapiens has had on our leafy, temperate, Goldilocks planet.

An Equator Full of Hurricanes Shows a Preview of End Times

The map looks terrifyingly unfamiliar. Not because of the outlines of the continents; those are comforting in their hooks, tails, splotches, and whorls. It’s the storms. Across the globe’s tropics right now, seven superstorms are swirling over oceans. Hurricane Florence is butting into the Carolinas on North America’s southeastern coast. Tropical storms Helene, Isaac, and Joyce are hovering over the Atlantic like jets stacked on approach to Charlotte. Learn about your ad choices: dovetail.prx.or...

Emissions Have Already Peaked in 27 Cities—And Keep Falling

Nothing against the countryside, which is lovely, but cities are where things happen. They are magnets for trade, and they're where cultures meet. They're also where more than half the world’s population lives, a number that will only continue to grow. Cities are also now serving as a unique testbed for responses to climate change—bolstering public transportation, erecting more efficient buildings, deploying renewable energy.

A New Robotic Fly Dips and Dives Like the Real Thing

Respect where respect is due: we humans may be mighty, but there’s still a foe that regularly dodges our best efforts to kill it: the fruit fly. Over millennia of evolution, fruit flies have adapted to burn their pursuers with enviable agility. Now researchers have built a robotic doppelganger that can twist and bank with astonishing speed. With two pairs of wings beating 17 times a second, it has a wingspan of over a foot and weighs just an ounce. Learn about your ad choices: dovetail.prx.org/a...

You Can Drink Champagne in Space—Yes, Really

Space travel used to be something that only people with the right stuff could experience. But advances in commercial space tourism is changing all of that. Virgin Galactic is registering passengers online. SpaceX announced it would send two lucky passengers around the moon in the next year or two. But space travel is still likely going to cater to a select few, in this case, people with the right amount of money. Virgin Galactic is currently pricing initial flights at $250,000.

Yes, You Can Boil Water at Room Temperature. Here's How

Sometimes it's right on the box of rice mix—the high altitude version of cooking instructions. Usually this means that your rice will have to cook a little bit longer if you are in Denver or at the top of Mount Everest. Of course that's just a joke. No one cooks rice at the top of Everest. But why are the instructions even different? Why does it matter where you cook? The answer has to do with boiling water. Go ask some people on the street about the boiling temperature of water.

Wisconsin's Floods Are Catastrophic—and Only Getting Worse

An entire summer’s worth of rain has fallen across a broad swath of the Midwest in recent days. The resulting record floods have wrecked homes and altered the paths of rivers, in one case destroying a waterfall in Minnesota. The worst-affected region, southwest Wisconsin, has received more than 20 inches of rain in 15 days– more than it usually gets in six months. Learn about your ad choices: dovetail.prx.org/ad-choices

Every night, an hour before bed, I stash my phone inside a drawer in my living room. Most days I retrieve it the following morning, when I'm heading out the door. It's a simple habit, but one that has helped me reclaim some focus from my smartphone—my personal fix for a growing problem that user experience researchers at Google recently called an "attention crisis."

New Space Robots Will Fix Satellites, or Maybe Destroy Them

People in the satellite industry are fond of automobile analogies. Like this one: Imagine that you buy a car and need it to run for 15 years, but you can’t change the oil or replace the alternator, let alone refuel it. That, they say, is the state of satellites. Once they’ve slipped the surly bonds of Earth, satellites pretty much just have to work, from the time they unfurl from their rocket fairing to the day they shut down for good.

This One-Armed Robot Is Super Manipulative (in a Good Way)

Give a man a fish, the old saying goes, and you feed him for a day—teach a man to fish, and you feed him for a lifetime. Same goes for robots, with the exception that robots feed exclusively on electricity. The problem is figuring out the best way to teach them. Typically, robots get fairly detailed coded instructions on how to manipulate a particular object. Learn about your ad choices: dovetail.prx.org/ad-choices

23andMe Cuts Off the DNA App Ecosystem It Created

Amy Mitchell started getting sick in 2012. Dizzy spells and fatigue became a part of her daily life, followed by numbness in her limbs and painful muscle spasms. After half a dozen doctors over two years couldn’t tell her what was wrong, she sent away for a 23andMe kit. At the time, the consumer DNA-testing company was only giving ancestry reports—the Federal Drug Administration had recently shut down 23andMe’s health information ambitions.

Startups Flock to Turn Young Blood Into an Elixir of Youth

In the early 2000s, a handful of young scientists at Stanford turned the university’s Palo Alto campus into the mouse-stitching-together capital of the world. Reviving a centuries-old procedure known as parabiosis, they connected the circulatory systems of dozens of pairs of rodents, young sutured to old, so that they’d pump one another’s blood back and forth.

This Hyper-Real Robot Will Cry and Bleed on Med Students

Hal the robot boy is convulsing. His head shakes back and forth so rapidly, it looks like he’s vibrating. His eyelids droop over his blue eyes and his mouth is ajar. He makes no sound, other than the faint whirs of his motors. Hal was built to suffer. He is a medical training robot, the sort of invention that emerges when one of the most stressful jobs on Earth tumbles into the uncanny valley. No longer must nurses train on lifeless mannequins. Hal can shed tears, bleed, and urinate. Learn about...

Why Scientists Are Using Frog Eggs to Power Tiny Electronics

Luigi Catacuzzeno lines up a long, thin needle against a frog egg. Peering at it through a microscope, he turns the knob of a machine to nudge the needle a fraction of a micron forward. Then he deftly punctures the membrane of the soft little egg to wire it to a small capacitor, an electrical component similar to a battery. This unusual arrangement is Catacuzzeno’s attempt to harvest energy from biological cells to power tiny electronics. Learn about your ad choices: dovetail.prx.org/ad-choices...

America’s Spaceport Boom Is Outpacing the Need to Go to Space

“The first mile is free,” Colorado’s governor, John Hickenlooper, says into a microphone. He’s smiling from a stage in Denver’s air and space museum, backed by a giant American flag that hangs near the bay doors of this repurposed military hangar. His audience has gathered to celebrate the FAA’s recent approval of a new Colorado spaceport, located a mile above sea level. They laugh at Hickenlooper's statement: They love this catchphrase.

Crispr Halted Muscular Dystrophy in Dogs. Someday, It Might Cure Humans

About ten years ago, British veterinarians discovered an unlucky family of King Charles Spaniels whose male pups sometimes came down with a mysterious set of maladies before their first birthday. They grew clumsy and weak, and they often choked on their own tongues. To blame was a mutation on their X chromosomes, in a gene that codes for a shock-absorbing muscle protein called dystrophin.
