An Itty-Bitty Robot That Lifts Off Like a Sci-Fi Spaceship

Credit where credit is due: Evolution has invented a galaxy of clever adaptations, from fish that swim up sea cucumber butts and eat their gonads, to parasites that mind-control their hosts in wildly complex ways. But it’s never dreamed up ion propulsion, a fantastical new way to power robots by accelerating ions instead of burning fuel or spinning rotors. The technology is in very early development, but it could lead to machines that fly like nothing that’s come before them. Learn about your ad...

How Extreme Heat Overwhelms Your Body and Becomes Deadly

The heat wave that scorched Europe last week felt like a red alert of climate change. Death Valley was cooler than southern France, where temperatures reached a record-breaking 114.6 degrees Fahrenheit. But as the heat broke and returned to relatively temperate 80s, another forewarning emerged. Civilizations need to adapt and protect themselves from extreme heat. More than anyone, the French are aware of just how deadly extreme heat can be. Learn about your ad choices: dovetail.prx.org/ad-choice...

The Debates Will Be About Climate—Disguised as Other Issues

Shhhhh. Don’t tell anyone, but Jay Inslee is going to get a presidential debate focused on climate change. Inslee, the governor of Washington state and one of two dozen candidates vying for the Democratic Party’s nomination for president, has been agitating for such a single-topic debate for months. Other candidates have signed onto the idea, and activists within the party have amplified the message. But Tom Perez, chair of the Democratic National Committee, said nuh-uh.

Desalination Is Booming as Cities Run out of Water

This story originally appeared on Yale Environment 360 and is part of the Climate Desk collaboration. Some 30 miles north of San Diego, along the Pacific Coast, sits the Claude “Bud” Lewis Carlsbad Desalination Plant, the largest effort to turn salt water into fresh water in North America. Each day 100 million gallons of seawater are pushed through semi-permeable membranes to create 50 million gallons of water that is piped to municipal users.

NASA Will Send a Helicopter to Hunt for Life on Saturn's Biggest Moon

On Wednesday, NASA announced it will send a spacecraft to the surface of Titan, Saturn’s largest moon and one of the leading candidates for finding extraterrestrial microbial life in our solar system. The Dragonfly mission will involve a small, drone-like rotorcraft lander that will be able to fly in small hops across Titan’s surface, covering more distance during its two-year mission than any planetary rover in history.

Want Your Kid to Play Pro Soccer? Sign Her Up for Basketball

The Women’s World Cup is in full swing, and today the Americans will face off against France in a battle to advance to the semifinals. This year’s American team is a strong one, both in personality (they are currently engaged in an equal-pay dispute with the US Soccer Federation) and in style—they started the tournament with a 13-0 rout over Thailand.

Senators Try—Again—to Solve the Nuclear Waste Debacle

On Thursday senators tackled the radioactive question of the nation's nuclear waste, this time with a new plan to circumvent the hot-potato politics that doomed Yucca Mountain and other proposals. A combination of new legislation that spreads out the nuclear waste burden and perhaps new technology could offer a new way forward. Everyday, the Department of Energy sends $2.2 million to the nation’s electric utilities to store spent nuclear fuel that has nowhere to go. Learn about your ad choices: ...

The Health Effects of Wildfire Smoke May Last a Lifetime

When smoke from California’s deadliest wildfire blew into downtown Sacramento last November, daylight blurred into dusk and the city’s air became among the world’s most polluted. The Camp Fire has long since been extinguished, but the health effects from the tiny particulate matter in the smoke, which penetrates into the lungs and ultimately into the bloodstream, could linger for years.

What Could Possibly Be Cooler Than RoboBee? RoboBee X-Wing

They used to call it RoboBee—a flying machine half the size of a paperclip that could flap its pair of wings 120 times a second. It was always tethered to a power source, limiting its freedom. Now, though, RoboBee becomes RoboBee X-Wing, as Harvard researchers have added solar cells and an extra pair of wings, freeing the robot to blast off to a galaxy far, far away. Or at least partway across the room, as it can only sustain flight for half a second at the moment, and only indoors. Learn about ...

A New Kind of Space Camp Teaches the Art of Martian Medicine

Ben Easter was delighted with the way his students were performing. He was especially delighted that a husband had just voted to kill his wife. The couple were both enrolled in the Martian Medical Analogue and Research Simulation, a continuing-education course for medical professionals who wanted to learn about health care in space by pretending to practice medicine in pretend space.

Fitted With Sensors, Antarctic Seals Track Water Temperatures

On a rocky island just off the coast of West Antarctica, ecologist Lars Boehme is standing face-to-face with a 1,500-pound elephant seal, eyeing the animal’s bulbous nose and jowls to see if he’s finished shedding his fur. When the seal opens his mouth wide to bellow, Boehme waves his hand in front of his face like he’s just smelled something foul. Learn about your ad choices: dovetail.prx.org/ad-choices

We Need a Data-Rich Picture of What's Killing the Planet

You’ve probably heard about the plague of plastic trash in the oceans. You’ve seen YouTube videos of sea turtles with drinking straws in their noses, or whales with stomachs full of marine litter. But how much plastic is out there? Where is it coming from? We don’t really know, because we haven’t measured it. “There’s a paucity of data,” says Marcus Eriksen, cofounder of the 5 Gyres Institute, a nonprofit focused on ending plastic pollution.

Neptune Is a Windy, Chilly, and Baffling Planet. Let's Go!

It was just after midnight at mission control center at NASA’s Jet Propulsion Laboratory, and Carl Sagan was exuberant. The Voyager 2 spacecraft had just completed its decade-long mission by making its closest pass to Neptune, before continuing on into interstellar space. It was the first—and so far only—spacecraft to visit the mysterious blue ice giant lurking at the edge of the solar system. Learn about your ad choices: dovetail.prx.org/ad-choices...

Lawyers in a Murder Trial Clash Over a DNA Forensics Method

On a large screen inside a packed Snohomish County courtroom, in Washington, a young Canadian couple smiled out at the dimmed room from the relaxed, faded scene of a party. It was the last known picture taken of Tanya Van Cuylenberg and Jay Cook together before they disappeared in November 1987. Their bodies were discovered days after they went missing, more than 60 miles apart. Thirty-one years later, William Talbott II is now standing trial as the first person to be accused of the double murde...

This Robot Fish Powers Itself With Fake Blood

This story begins thousands of feet up in the air with migratory birds, and ends with a robotic fish swimming through the water below. To prepare for their journeys, birds fatten up big time, perhaps doubling their weight, essentially turning themselves into feathered batteries. Over many days and many miles, they burn that energy reserve to power their wings and keep themselves from starving and freezing. Eventually they reach their destinations emaciated.

The Midwest's Farms Face an Intense, Crop-Killing Future

The flooding that devastated the Midwest this spring damaged infrastructure and prevented farmers from getting crops planted on time. Though scientists can’t say if one storm or one wet season is the result of climate change, so far this year’s heavy rains are a perfect illustration of what scientific models of climate change predict for the region. And it’s only going to get more intense. Learn about your ad choices: dovetail.prx.org/ad-choices...

The Physics of Actually Flying Around in an Iron Man Suit

I was fairly impressed with the first episode of Savage Builds, which is now airing on the Discovery Channel. It's basically a show that lets Adam Savage (from MythBusters) do whatever he wants. In this case, he attempts to build an actual real-life Iron Man suit. SPOILER ALERT: He mostly succeeds. This is accomplished by printing out Iron Man armor pieces in titanium and then adding the jet suit from Gravity Industries on top of that. Yes, there is a real-life flying suit.

These Sumptuous Images Give Deep Space Data an Old-World Look

Eleanor Lutz has a running list of scientific topics she wants to find data sets for. It’s not her job exactly. A biologist with wide-ranging curiosity, Lutz moonlights as a data-driven illustrator who transforms public data sets into arrestingly beautiful visual objects. She’s made digital trading cards of animated viruses (who knew HPV could be so mesmerizing), and infographics on plant species that have evolved to withstand forest fires.

A New Fuel for Satellites Is So Safe It Won’t Blow Up Humans

Later this month, a small satellite will hitch a ride on a SpaceX Falcon Heavy rocket for the world’s first demonstration of “green” satellite propellant in space. The satellite is fueled by AFM-315, which the Air Force first developed more than 20 years ago as an alternative to the typical satellite juice of choice, hydrazine.

Remembering Gabriele Grunewald, Who Ran For Herself and Others

The image is hard to look at now without crying: a thick red scar, carved across Gabriele Grunewald’s midriff as she flies around the track. At first it looks like it shouldn’t be there; perhaps it’s just an out-of-place shadow. But soon it becomes obvious what it truly is: a symbol of perseverance and pain.

Blame Utilities for Wildfires. But Blame Everyone Else Too

It’s hard to feel sorry for the California utility PG&E, considering that officials blamed its equipment for starting nearly every major fire in the state in 2017. Last year, it was responsible for igniting the Camp Fire, which killed 85 and destroyed almost 20,000 structures. The problem is typically wind, which jostles electric lines, raining sparks onto parched vegetation below. So just cut the power when it’s particularly hot and dry and windy, right? If only it were so easy. Learn about...

Estimate the Energy of an Utterly Massive Wind Turbine

It's amazing that we can get electrical power just from the wind, but that's exactly what happens with a wind farm. It's a collection of wind turbines in a particular location with abundant wind. And as with many things, bigger is better. The Hornsea Wind Farm, for example, is being built 75 miles off the coast of Yorkshire, England, and upon completion it is expected to be the biggest offshore wind farm in the world.

The Top Secret Cold War Project That Pulled Climate Science From the Ice

In 1961—the year before he became the anchorman for CBS News—Walter Cronkite visited Camp Century, an unusual military compound on the Greenland ice sheet. Carved under the snow and ice, Camp Century had a main street and prefab housing for 250 soldiers and scientists—all powered by a pint-sized nuclear reactor.

New Space Telescopes Could Look Like Giant Beach Balls

If we ever have giant inflatable telescopes in space, you can thank Chris Walker’s mom. Years ago, Walker was making chocolate pudding when he had to interrupt his culinary undertaking to field a phone call from his mother. He took the pudding off the stovetop, covered it with plastic wrap, and placed the pot on the floor by his couch. When the call was finished, he was startled to find an image of a lightbulb from a nearby lamp hovering over the end of the couch. Learn about your ad choices: do...

California’s Vaccination Rate Slips as Medical Exemptions Rise

In the last few years California has gained ground in its fight to protect children from infectious diseases. But new data released this week shows that the state’s vaccination rate declined for the second year in a row. Last fall 94.8 percent of California kindergartners had received all their shots, down from 95.6 in 2016-2017. That drop may look small, but California has about as many kindergartners as Wyoming has people. Learn about your ad choices: dovetail.prx.org/ad-choices...
