AI Just Learned How to Boost the Brain's Memory
When it comes to black boxes, there is none more black than the human brain. Our gray matter is so complex, scientists lament, that it can’t quite understand itself. But if we can’t grok our own brains, maybe the machines can do it for us. Learn about your ad choices: dovetail.prx.org/ad-choices

The WIRED Guide to Climate Change
The world is busted. For decades, scientists have carefully accumulated data that confirms what we hoped wasn’t true: The greenhouse gas emissions that have steadily spewed from cars and planes and factories, the technologies that powered a massive period of economic growth, came at an enormous cost to the planet’s health. Today, we know that absent any change in our behavior, the average global temperature will rise as much as 4 degrees Celsius by the end of the century.

The Physics of One of the Craziest Big Air Snowboard Tricks Ever
Behold the stomach-clenching spectacle of the quad cork 1800. The dizzying snowboarding trick—first landed by British Olympian Billy Morgan, above—involves catapulting off a ramp into four off-axis flips (called corks) and five full spins. Only four people have ever completed the 1,800-degree stunt. Learn about your ad choices: dovetail.prx.org/ad-choices

Could a Vaccine Protect Football Players From Concussions?
It’s been a turbulent year for the NFL. Ratings plummeted 12 percent in the regular season, even more during the playoffs. It’s hard to know what hurt the league more, its public feuding with the White House over players protesting police brutality during the national anthem or the fact that people don’t watch TV anymore.

SpaceX Gears Up to Finally, Actually Launch the Falcon Heavy
After nearly seven years of varying concepts, redesigns, and delays, SpaceX is poised to launch the Falcon Heavy rocket next week on its maiden flight. Last week, SpaceX performed a hold-down firing of the massive rocket’s 27 engines, creating a towering exhaust plume and jolting the space coast with over 5 million pounds of thrust.

The Squishy Ethics of Sex With Robots
Sarah Jamie Lewis was thinking about an internet-connected cock ring. As a computer scientist, she could understand the nominal use case. It was studded with accelerometers and other sensors. People with penises were supposed to put it on before having penetrative sex and record things like thrust length, speed, overall time of session … the things that sex experts tell people not to worry about but people with penises worry about anyway.

The Shrinking Building in Ant-Man and the Wasp Would Cause Massive Problems
Maybe you are one of those humans that avoids all trailers because they spoil the movie too much. I am not one of those humans. Which is why I immediately watched a trailer that came out this week for the upcoming Marvel movie Ant-Man and the Wasp. Although I was a huge comic book fan growing up, I never really got into Ant-Man. But the first Ant-Man movie was better than expected—and now I'm looking forward to this sequel. If you don't know about Ant-Man, I'll give you a quick overview. Learn about your ad choices: dovetail.prx.org/ad-choices

A Family’s Race to Cure a Daughter’s Genetic Disease
One July afternoon last summer, Matt Wilsey distributed small plastic tubes to 60 people gathered in a Palo Alto, California, hotel. Most of them had traveled thousands of miles to be here; now, each popped the top off a barcoded tube, spat in about half a teaspoon of saliva, and closed the tube. Some massaged their cheeks to produce enough spit to fill the tubes. Learn about your ad choices: dovetail.prx.org/ad-choices

What Good Is Crispr If It Can't Get Where It Needs to Go?
Your DNA is your body’s most closely guarded asset. To reach it, any would-be-invaders have to get under your skin, travel through your bloodstream undetected by immune system sentries, somehow cross a cell membrane, and finally find their way into the nucleus. Most of the time, that’s a really good thing. These biological barriers prevent nasty viruses from turning your cells into disease-making factories.

How Long Beach Is Trying to Cool Down
This storyoriginally appeared on CityLaband is part of theClimate Deskcollaboration. In a coastal city, it’s easy to assume the greatest climate threat comes from the rising ocean. But in Long Beach, California, the biggest danger is not the sea, but the sun. “We have to deal with sea-level rise,” Long Beach Mayor Robert Garcia said. “But it’s not our biggest challenge. The increase in temperature is the real concern right now. Learn about your ad choices: dovetail.prx.org/ad-choices

Can Our Phones Save Us From Our Phones?
Hi. My name is Robbie, and I'm addicted to browser tabs. For years, I deluded myself into thinking they were an efficient way to gather information on a given subject. Or subjects. Sub-subjects, too. You see the problem. Which is why, for the past few months, I've been experimenting with a Chrome extension called xTab. It works by limiting the number of tabs I can have open in a given browser window. Learn about your ad choices: dovetail.prx.org/ad-choices

Meet the Company Trying to Democratize Clinical Trials With AI
A decade ago, Pablo Graiver was working as a VP at Kayak, the online airfare aggregator, when he sat down to dinner with an old friend—a heart surgeon from his home country of Argentina. The talk turned to how tech was doing more to save folks a few bucks on a flight to Rome than to save people’s lives. The biggest problem in healthcare? “Clinical trials,” she said. “They’re a disaster. Learn about your ad choices: dovetail.prx.org/ad-choices

Don’t Call It a Blood Moon. Or Supermoon. Or Blue Moon
On Wednesday, humanity will be treated to a celestial trifecta: A supermoon (meaning it’s relatively close to Earth), but also simultaneously a blood moon (it’ll be orange or red), but also simultaneously a blue moon (the second full moon in one calendar month) will pass in the shadow of Earth, for a total lunar eclipse. It’s going to be righteous. Learn about your ad choices: dovetail.prx.org/ad-choices

Yes, There Is Gravity in Space
This week, I settled down to watch the first episode of The 100. If you haven't seen the show, I'll just point out that it takes place in the near future (though it ran, on the CW, in the near past). For reasons that I won't get into, there is a spacecraft with a bunch of teenagers that is traveling from a space station down to the surface of the Earth. During the reentry process, one kid wants to show that he is the master of space travel and that he's awesome. Learn about your ad choices: dovetail.prx.org/ad-choices

Scientists Hate the NIH’s New Rules for Experimenting on Humans

Why No Gadget Can Prove How Stoned You Are
If you’ve spent time with marijuana—any time at all, really—you know that the high can be rather unpredictable. It depends on the strain, its level of THC and hundreds of other compounds, and the interaction between all these elements. Oh, and how much you ate that day. And how you took the cannabis. And the position of the North Star at the moment of ingestion. OK, maybe not that last one. Learn about your ad choices: dovetail.prx.org/ad-choices

How Much Kinetic Energy Could Black Panther Collect from Bullets?
A new clip from the upcoming movie Black Panther was recently shown during an episode of Ellen. In the scene (which I assume isn't a spoiler, since it was on TV), the Black Panther is in pursuit of (or being pursued by) some people in another car. As the Black Panther rides on top of the car (which is, of course, the most efficient way to travel as a superhero), the bad guys are pelting him with bullets. Honestly, I shouldn't make such judgements—maybe they're not bad, just misunderstood. Learn about your ad choices: dovetail.prx.org/ad-choices

SpaceX Test Fires Its Falcon Heavy Rocket for the First Time
The long-awaited Falcon Heavy rocket roared to life on Wednesday at 12:30 pm Eastern, as SpaceX fired up the 27 Merlin engines that power the triple-booster rocket at Kennedy Space Center. Perched atop what CEO Elon Musk claims will be the most powerful lift vehicle in the world is the billionaire’s Tesla Roadster, which will launch toward a Mars elliptical orbit on the Falcon Heavy’s upcoming maiden flight.

The Science of Why Swearing Physically Reduces Pain
For a very long time, conventional wisdom held that swearing was not a useful response to pain. Many psychologists believed that swearing would actually make pain feel worse, thanks to a cognitive distortion known as catastrophizing. When we catastrophize we leap to the conclusion that the bad thing that is currently happening is the absolute worst thing. Learn about your ad choices: dovetail.prx.org/ad-choices

Why Robots Should Shake the Bejeezus Out of Cherry Trees
I don’t think sci-fi saw this coming. For so long, futuristic books and films have promised us robots like C-3PO that translate alien languages and assist us in hijinks. Or ones like Rosie that clean our houses. Or, on the other end of the spectrum, robots that level our houses and destroy humanity. Looking at you, Arnold. The reality of modern robotics couldn’t be more different. These days, it’s more about developing robots that ... shake the bejeezus out of cherry trees.

The Second Coming of Ultrasound
Before Pierre Curie met the chemist Marie Sklodowska; before they married and she took his name; before he abandoned his physics work and moved into her laboratory on Rue Lhomond where they would discover the radioactive elements polonium and radium, Curie discovered something called piezoelectricity. Some materials, he found—like quartz and certain kinds of salts and ceramics—build up an electric charge when you squeeze them. Sure, it’s no nuclear power.

How Smallsats Could Make a Big Difference for NASA and NOAA
Information from space has historically been the province of the rich and powerful. Big Earth-observing satellites can cost hundreds of millions of dollars to build and launch, and the price of their data scales accordingly. Scrappy scientific upstarts have, for a while, been building smallsats to get orbital data on the cheap. Learn about your ad choices: dovetail.prx.org/ad-choices

How Engineering Earth’s Climate Could Seriously Imperil Life
Travel with me to the year 2100. Despite our best efforts, climate change continues to threaten humanity. Drought, superstorms, flooded coastal cities. Desperate to stop the warming, scientists deploy planes to spray sulfur dioxide in the stratosphere, where it converts into a sulfate aerosol, which reflects sunlight. Thus the planet cools because, yes, chemtrails. Learn about your ad choices: dovetail.prx.org/ad-choices

The Little Rocket That Could Sends Real Satellites to Space
The launch company Rocket Lab has amusing names for its missions. The first, in May, was called “It’s a Test” (it was). When the staff debated what to call the second launch of their diminutive Electron rocket, so sized (and priced) specifically to carry small satellites to space, they said, “Well, we’re still testing, aren’t we?” They were.

Cancer Diagnosis from a Blood Draw? Liquid Biopsies Are Still a Dream
Nick Papadopoulos tracks down tumors for a living. Not with X-rays or CT scans, but with DNA. The oncologist and director of translational genetics at the Johns Hopkins Kimmel Cancer Center has spent decades uncovering the unique sets of mutations that define cancers—the kind of genetic signals that not only drive tumor formation and metastasis, but distinguish one cancer from another.

NASA Just Proved It Can Navigate Space Using Pulsars. Where to Now?
Half a century ago, astronomers observed their first pulsar: a dead, distant, ludicrously dense star that emitted pulses of radiation with remarkable regularity. So consistent was the object's signal that astronomers jokingly nicknamed it LGM-1, short for "little green men." It wasn't long before scientists detected more signals like LGM-1. That decreased the odds that these pulses of radiation were the work of intelligent extraterrestrials. Learn about your ad choices: dovetail.prx.org/ad-choices

Global Warming Predictions May Now Be a Lot Less Uncertain
If one is the loneliest number, two is the most terrifying. Humanity must not pass a rise of 2 degrees Celsius in global temperature from pre-industrial levels, so says the Paris climate agreement. Cross that line and the global effects of climate change start looking less like a grave situation and more like a catastrophe. The frustrating bit about studying climate change is the inherent uncertainty of it all. Learn about your ad choices: dovetail.prx.org/ad-choices

The Physics of the 69-Degree Intersection That Kills Cyclists
Sometimes when I see an awesome analysis on the internet, I just want to make it more awesomer. Really, this should be everyone's goal on the internet—either make stuff or make it more awesome.

Job Alert: How Would You Like to Babysit Robots?
Book a night at LAX’s Residence Inn and you may be fortunate enough to meet an employee named Wally. His gig is relatively pedestrian—bring you room service, navigate around the hotel's clientele in the lobby and halls—but Wally’s life is far more difficult than it seems. If you put a tray out in front of your door, for instance, he can’t get to you. If a cart is blocking the hall, he can’t push it out of the way.

Scientists Discover Clean Water Ice Just Below Mars' Surface
Locked away beneath the surface of Mars are vast quantities of water ice. But the properties of that ice—how pure it is, how deep it goes, what shape it takes—remain a mystery to planetary geologists. Those things matter to mission planners, too: Future visitors to Mars, be they short-term sojourners or long-term settlers, will need to understand the planet's subsurface ice reserves if they want to mine it for drinking, growing crops, or converting into hydrogen for fuel.

How Dark Matter Physicists Score Deals on Liquid Xenon
If you want to build and run a $70 million dark matter detector, you're going to have a hefty shopping list. You'll need to buy hundreds of photomultiplier tubes, set up elaborate electronics, and pay graduate students, for starters. And 20 percent of your cash is going to go to just one thing: xenon gas. You'll need 200 steel bottles of the stuff, purified from the Earth’s atmosphere, at a price that can fluctuate wildly around $100,000 a bottle.

A Robot That Tugs on Pig Organs Could Save Human Babies
The pig looks like any other pig, only it's been wearing a backpack for a week—in the name of science. Just behind its head sits a control box, with a battery and processor, from which runs a cable that enters through the pig’s flank. Once inside, the cable attaches to a very special robot clamped onto the pig's esophagus, the pathway to the stomach. Little by little, the robot lengthens, in turn lengthening the tube. The robot attached to a segment of esophagus.Damian et al. Learn about your ad choices: dovetail.prx.org/ad-choices

Can an Arrow Fired Straight Up Fall Fast Enough to Kill You?
In a recent episode of Mythbusters, Brian and Jon (the new MythBusters) wanted to see what happens when you shoot an arrow straight up into the air. It will obviously come back down—but would it still be moving fast enough to kill you? If you are a MythBuster, the best option is to actually shoot an arrow straight up into the air and measure its velocity on impact. But for normal people, it might be better to just calculate the final arrow speed. Learn about your ad choices: dovetail.prx.org/ad-choices

Scientists Figure Out How to Make Muscles from Scratch
For the past several years, Nenad Bursac has been trying to make muscles from scratch. A biological engineer at Duke, Bursac came close in 2015, when his lab became the first to grow functional human skeletal muscle in culture. "Functional" being the operative word. Like the muscle fibers in, say, your bicep, the tissues could contract and generate forces in response to things like electrical pulses and shots of chemicals.

Scientists Just Solved a Major Piece of the Opioid Puzzle
When it comes to tackling the opioid crisis, public health workers start with the drugs: fentanyl, morphine, heroin. But biochemists have a different focus: Not the opioids, but opioid receptors—the proteins the drugs latch onto within the body. These receptors embed themselves in the walls of cells throughout the brain and peripheral nervous system. Learn about your ad choices: dovetail.prx.org/ad-choices

Salvia Leads Chemists on a Psychedelic Existential Journey
On August 2, synthetic organic chemist Ryan Shenvi stood before 300 people at the Natural Products and Bioactive Compounds conference and told them something he knew was sacrilegious: He’d synthesized salvinorin A, the active ingredient in the wildly intense hallucinogen salvia, and he hadn’t just copied a molecule, as synthetic organic chemists are wont to do.

Let's Do the Physics of the Giant Driving Cities in Mortal Engines
Next December, there'll be a new entrant into the end-of-year, blockbuster science fiction movie category: the Peter Jackson film Mortal Engines. A teaser trailer for it dropped just before the holidays, and there's really only one thing you need to know about it. Driving cities. Driving cities! Now, I know the movie is based on a book series, which probably has a lot of detail about these giant ambulatory dwellings.

How You Could Get an Early Warning for the Next Big Quake
At 2:39 am Thursday morning, millions of Bay Area residents from Sacramento to San Jose were shaken awake by the rolling tremble of a 4.4 magnitude earthquake.

A Clever New Robotic 'Muscle' Seriously Lifts, Bro
Oh, the poor humanoid robots. After decades of development, they're still less sprinty Terminator and more … octogenarian on sedatives.

Why the Bomb Cyclone Hitting the East Coast Is So Unusual
Now, the first thing you should know about a bomb cyclone is it’s just a name—and unlike a sharknado, it’s not a literal one. The very real scientific term describes a storm that suddenly intensifies following a rapid drop in atmospheric pressure. Bombing out, or “bombogenesis,” is when a cyclone’s central pressure drops 24 millibars or more in 24 hours, bringing furious winds that can quickly create blizzard conditions and coastal flooding.

The Physics of Plastic Sheets … and Their Invisible Force Fields?
When you wander around the internet, sometimes you can find some crazy stuff. Check this out: It's an old account of a weird phenomena created by giant plastic sheets at 3M Corporation. In short, these fast-moving, electrically-charged plastic sheets created some type of effect that prevented humans from passing through an invisible wall.
