A Crucial Climate Mystery Hides Just Beneath Your Feet
This storyoriginally appeared on Gristand is part of theClimate Deskcollaboration. What Jonathan Sanderman really wanted was some old dirt. He called everyone he could think of who might know where he could get some. He emailed colleagues and read through old studies looking for clues, but he kept coming up empty. Sanderman was looking for old dirt because it would let him test a plan to save the world. Learn about your ad choices: dovetail.prx.org/ad-choices

How Hard Does Thor Hit Hulk in That Ragnarok Trailer? Let’s Do the Physics!
I can’t imagine a blockbuster movie about superheroes without some cool physics. After all, these aren’t dramas, but action movies with jumping and flying and punching. Of course, the point of the jumping and flying and punching is to advance the story, not provide a physics lesson. But nothing says they can’t do both. The firsttrailer for Thor: Ragnarokprovides a great chance to do this. Learn about your ad choices: dovetail.prx.org/ad-choices

To Save Florida’s Famous Oranges, Scientists Race to Weaponize a Virus
On a plate, a single banana seems whimsical—yellow and sweet, contained in its own easy-to-open peel. It is a charming breakfast luxury as silly as it is delicious and ever-present. Yet when you eat a banana the flavor on your tongue has complex roots, equal parts sweetness and tragedy. In 1950, most bananas were exported from Central America. Guatemala in particular was a key piece of a vast empire of banana plantations run by the American-owned United Fruit Company. Learn about your ad choices: dovetail.prx.org/ad-choices

The ‘Most Dangerous’ Volcano Can Be a Tricky Thing to Pin Down
I know you've all seen lists like this before: what is the "world's most dangerous volcano"? Most of the time, that discuss devolves quickly into something about "supervolcanoes", which is very exciting and all because they can generate massive eruptions. However, they are far from being the "most dangerous" volcano. Learn about your ad choices: dovetail.prx.org/ad-choices

Pricey Technology Is Keeping People Alive Who Don’t Want to Live
Some people just want to die. Not because they are trapped by depression, anxiety, public embarrassment, or financial ruin. No, these poor few have terminal illnesses. Faced with six months to live, and the knowledge that the majorityof those 180 days will be bad ones,theyseek a doctor’s prescription for an early death. Soon, terminal patients in California will have that option. Learn about your ad choices: dovetail.prx.org/ad-choices

Why You Should Put Your Supercomputer in Wyoming
Travel just few miles west of bustling Cheyenne, Wyoming, a you’ll find yourself in big-sky country. Tall-grass plains line the highway, snow-packed peaks pierce the sky, and round-edged granite formations jut out of the ground. But in this bucolic scene sits an alien building: a blocky, almost pre-fab structure with a white rotunda, speckled with dozens of windows that look out onto the grounds. Inside, it’s home to two supercomputers that focus on the vast landscape above. Learn about your ad choices: dovetail.prx.org/ad-choices

Coastal Inundation Reveals the Upside of Climate Change
In Miami Beach, they call it “sunny-day flooding.” You’ll be hanging out downtown under clear blue skies—only to see, whoa, the streets slowly filling with water. Miami Beach, Florida, is a coastal city built on porous limestone, so as climate change melts polar ice into the oceans, water is literally pushed up out of the ground. “It’s an eerie, scary, unnerving feeling, like something out of a sci-fi movie,” says Philip Levine, mayor of the city of 90,000.

You Could Soon Print Out Simple Electronics With Your Deskjet
Computers used to require entire buildings to operate. Now they fit in our pockets. Similarly, factory-size electronics manufacturing is approaching a contraction. Want proof? Look at that $50 printer on your desk and imagine, instead of using it to spit out a hard copy of that thank-you note, that you used it to print some digital memory. Not enough memory to power a laptop. Think smaller, like smart tags to inventory all the crap in your workshop. Learn about your ad choices: dovetail.prx.org/ad-choices

Elon Musk Isn’t the Only One Trying to Computerize Your Brain
Elon Musk wants to merge the computer with the human brain, build a “neural lace,” create a “direct cortical interface,” whatever that might look like. In recent months, the founder of Tesla, SpaceX, and OpenAI has repeatedly hinted at these ambitions, and then, earlier this week, The Wall Street Journal reported that Musk has now launched a company called Neuralink that aims to implant tiny electrodes in the brain “that may one day upload and download thoughts.

Want to Play Scrabble Like a Pro? Here’s Your Memory Trick
Bennett Schwartz is one of the nation’s leading memory experts, and when I visited him in his office at Florida International University, he was standing at his desk. A soft sunlight crowded the room. Large windows framed the palm tree-lined quad outside. Dressed in a short-sleeved shirt and slacks, Schwartz appeared to be quietly talking to himself, with hushed, mumbled words, and for a long moment, it seemed as if he was some sort of monk, living in another, more esoteric world.

The Fanged Fish That Drugs Its Enemies With Opioids
Not unlike the ant-decapitating fly and the satanic leaf-tailed gecko, the fang blenny’s name does not disappoint. This tiny fish wields two massive teeth that it uses to gouge chunks out of much larger fish and, in a bind, scrap its way out of the grasp of a predator. And one particular group of fang blenny even injects venom, just like a snake, to give its attackers that extra what-for. That’s all very, very bizarre behavior for a fish—behavior that today gets even more bizarre. Learn about your ad choices: dovetail.prx.org/ad-choices

A Russian Volcano Just Erupted for the First Time in Centuries
This weekend saw a new eruption from Kambalny in southern Kamchatka. Now, the Kamchatka Peninsula is a very volcanically active area, with multiple eruptions going on simultaneously much of the time. There are certain volcanoes that are in almost-constant unrest, like Shiveluch, Kliuchevskoi, and Karymsky. However, Kambalny is not one of the usual suspects for activity. This changed when a dark grey ash plume was spotted by Earth-observing satellites on March 25. Learn about your ad choices: dovetail.prx.org/ad-choices

In Science, You Can’t Always Get What You Want
I teach an introductory physics course to elementary education majors, but my lessons aren't really about physics. At first glance, it might seem that they are, but it's a trick. The course examinesthe nature of science. That's what makes it so awesome. When I talk about the nature of science, I don't mean the list of steps outlined on thatposter in your fourth grade classroom-that's not howscience works.

What’s the Point of Going to Space if You Don’t Make Booze?
Last week, Anheuser-Busch announced a plan to sponsor research aboard the International Space Station to learn how to someday serve beer to astronauts on Mars. This is a dumb plan—not because beer is bad, or because astronauts responsible for settling the red planet won’t deserve a brewski at the end of a sol. It’s just, why beer? Distilled spirits—liquor—has always been a better fuel for exploration, or at least for explorers. Learn about your ad choices: dovetail.prx.org/ad-choices

Meet the Woman Who Can See With Her Ears
The last thing twenty-one-year-old Pat Fletcher saw before the explosion was the chemical-filled steel tank beside her suddenly ballooning outward. With alarm she realized the plastic hose in her hand had grown unusually hot. Then the world flashed blindingly bright and turned a brilliant blue, the color of the flames engulfing her body. When she awoke, Pat thought she might be dreaming. The world around her was featureless and dark, as though she were lost in a gray, smoky fog.

Somebody Just Buy the ISS Already
Two hundred and twenty miles above Earth flies the International Space Station, a $70 billion1 engineering marvel that no onehas any idea what to do with. Short term, sure: astronauts, science, zero-gravity viral videos. Longer term, spending $3 billion to $4 billion annually to keep the ISS running conflicts with NASA’s other ambitions, like visiting Mars. Congress holds NASA’s purse strings, so ultimately the decision lies with that august body. Learn about your ad choices: dovetail.prx.org/ad-choices

The Billionaire on a Mission to Save the Planet From Trump
Tom Steyer isn't your average California tree hugger. The former hedge fund manager—number 1,121 on Forbes' wealthiest people list, with $1.61 billion—was once best known for turning $15million into $30billion in about two decades. But then he went hiking. Steyer and environmental activist and author Bill McKibben spent a day trudging through the Adirondacks. Learn about your ad choices: dovetail.prx.org/ad-choices

Catnip Ain’t the Only Plant That’ll Send Your Kitty to Blissville
The feline approaches its prey. Slowly at first, then crescendoing to a pounce that lands near, but not on the unmoving target. The cat bats an investigatory paw, then claws its target and yanks it faceward. But the cat does not bare its fangs; it does not bite. It closes its eyes and rubs the prey—a sock flecked with bits of dried herb—across its whiskers, then falls to the ground, its body humming with purrs that oscillate into soft meows.

Got a Sock Stuck in Your Vacuum? It’s Time for Some Physics
Imagine yourself running the vacuum cleaner over the carpet when all of sudden—a sock. Boom. It’s stuck in the hose, the whine of the vacuum getting higher andhigher, louder andlouder. It sounds like overload is imminent, like the motor is working way too hard. But is it? To know, let’s look at some cool physics principles. Vacuum cleaners don’t actually suck. They blow. No, really. They use a fan that blows air out of a hole. Learn about your ad choices: dovetail.prx.org/ad-choices

Artificial Intelligence Is Learning to Predict and Prevent Suicide
For years, Facebook has been investing in artificial intelligence fields like machine learning and deep neural nets to build its core business—selling you things better than anyone else in the world. But earlier this month, the company began turning some of those AI tools to a more noble goal: stopping people from taking their own lives. Admittedly, this isn’t entirely altruistic. Having people broadcast their suicides from Facebook Live isn’t good for the brand. Learn about your ad choices: dovetail.prx.org/ad-choices

Trump’s Budget Would Break American Science, Today and Tomorrow
You can go ahead and assume President Trump’s proposed federal budget will never be the actual federal budget. Members of Congress from every political persuasion will find a lot to hate about it, and they’re the ones who have to approve it—assuming they can sort out the arcane, procrustean rules for getting any budget passed in Washington.

The Feds Are Spending Millions to Help You Survive Nuclear War
Last week, as tens of thousands of US and South Korean soldiers gathered at a base in Iwakuni, Japan for an annual joint military exercise, North Korea fired four ballistic missiles from Pyongyang into the sea off Japan’s northwest coast. In a world where the US is headed by a Twigger-happy political neophyte and the risk of a Cold War reboot looms larger with each Wikileaks disclosure, this demonstration wasn’t just an empty display of dictatorial propaganda.

The Beauty of Mathematics: It Can Never Lie to You
A few years back, a prospective doctoral student sought out Sylvia Serfaty with some existential questions about the apparent uselessness of pure math. Serfaty, then newly decorated with the prestigious Henri Poincaré Prize, won him over simply by being honest and nice. “She was very warm and understanding and human,” said Thomas Leblé, now an instructor at the Courant Institute of Mathematical Sciences at New York University.

Italy’s Etna Volcano Throws Lava Bombs in Its First Big Eruption of 2017
After one of the most quiet years in decades, Etna has decided to make 2017 a little more exciting. Early this week, the volcano had a moderate strombolian eruption, what the folks who monitor Etna call a “paroxysm,” that produced a lava fountain over the summit of the volcano. Strombolian eruptions(named after nearby Stromboli)are caused by gas-rich magma reaching the surface and erupting explosively. Learn about your ad choices: dovetail.prx.org/ad-choices

California Needs Atmospheric Rivers. But Like, Not This Many
California likes whiplash weather. The state’s greenery, rivers, and dams are used to dry summer and wet winters. But recently—as the land has gone from parched and on fire to a complete deluge—things have gotten out of hand. From the strained Oroville dam to the flooding in San Jose last weekend, all this water, water everywhere has a single meteorological source: atmospheric rivers.

Inside the Extreme Machine That Mimics Bombs and Black Holes
It's 5:15 a.m. and dark when I drive over Raton Pass, the 7,835-foot-high saddle right at the boundary between Colorado and New Mexico. Animal crossing signs whiz by my window: first a clip-art bear, then an elk, then a deer. "Watch out" is an apt way to enter the state, particularly on this trip: New Mexico is the birthplace of the nuclear bomb and the site of its first test. That initial blast occurred southeast of Socorro, under the auspices of Los Alamos National Lab-led Manhattan Project. Learn about your ad choices: dovetail.prx.org/ad-choices

7 Earth-Like Worlds Orbit a Star So Cool, You Didn’t Know It Existed
Forty light years away, a small, orange star called Trappist-1 sits unnoticed in the sky. You can’t see it with your bare eyes—it burns colder than the brightly shining stars that fill the night sky, the ones that have inspired millions of people to imagine life beyond Earth. But most stars in the galaxy are neither big nor bright. And it’s those abundant, dim dwarfs that might actually be the best place to look for worlds capable of supporting life.

Forget Weather Apps: Measure the Wind Yourself With an Old Electric Motor
One of the best ways to measure wind speed is to usean anemometer. You could go out and buy one, but I find it much more fun to build my own. There areseveral types of anemometer tochoose from, but I am going to build one that uses electromagnetic induction. Normally, we think of electric potential as something you can get from a battery. But you also can get it from induction. It turns out that changing magnetic field also creates an electric potential. Learn about your ad choices: dovetail.prx.org/ad-choices
