Doctors and Patients Reel After Trump’s Immigration Ban

Azi Tourkamani is eight months pregnant and working 12-hour shifts at St. Joseph’s Hospital in Syracuse, New York. She’s a resident doctor in internal medicine. Most days she has so many patients she doesn’t have time to stop and eat lunch; she eats as she walks from floor to floor treating patients. Learn about your ad choices: dovetail.prx.org/ad-choices

Spill-Proof Cups Aren’t Magic. They’re Physics!

They call it the Mighty Mug-and the idea is that it isn't easily knocked over. Of course, you can tip just about anything over if you try hard enough. But really, how does this work? Let me be clear: I haven't actually played with a Mighty Mug-so most of this is just physics-based speculation. It seems the key component of this mug is some type of suction cup on the bottom. When you put the cup down, a rubber seal forms with a smooth table surface. Learn about your ad choices: dovetail.prx.org/ad-choices

Ever Had a Really Long Acid Trip? Now Science Knows Why

Few tropes in modern America are as enduring as the LSD Trip Gone Far Too Long. It should all be over after a few hours, right? OK maybe not. Eight? Ten? Probably should have cleared more of my calendar. Even though science has long had an intimate relationship with LSD-chemist Albert Hofmann first synthesized it way back in the '30s-why the drug insists on producing such lengthy hallucinations hasn't been so clear. Until now. Learn about your ad choices: dovetail.prx.org/ad-choices

Trump’s Muslim Ban Isn’t Just Inhumane—It’ll Make America Dumber

Alireza Edraki spends weekends in the lab. It’s what he does. For the past three years, test tubes full of bacteria have been his constant companions. Not this weekend. “I’m so stressed out that I can’t work,” he says. Edraki is a third-year PhD candidate at the University of Massachusetts’ medical school in Worcester. You know Crispr/CAS-9, the gene-editing technology that’s in all the headlines lately? That’s what Edraki works on. Learn about your ad choices: dovetail.prx.org/ad-choices

So You Wanna Get Into Physics. Here Are Three Tips and Tricks

For many, it's the start of a new semester of physics labs. That means there are new students in that introductory course. Of course, no one is really 100 percent ready to start these labs-but that's OK. Here are three big ideas that I find students need to work on to be successful in lab.

First Human-Pig Chimera Is a Step Toward Custom Organs

Every day, 22 people in America die while waiting for an organ transplant. But when scientists can grow replacement livers or kidneys or pancreases inside of animal hosts, medicine’s organ shortage may end. That’s the hope anyway—and this week there’s more reason to hope than ever that it might become reality. The key to producing human organs in other animals is the chimera, a mixture of cells from more than one species growing together as a single animal.

How Being Bored Out of Your Mind Makes You More Creative

“I’m dying of Boredom,” complains the young wife, Yelena, in Chekhov’s 1897 play Uncle Vanya. “I don’t know what to do.” Of course, if Yelena were around today, we know how she’d alleviate her boredom: She’d pull out her smartphone and find something diverting, like BuzzFeed or Twitter or Clash of Clans. If you have a planet’s worth of entertainment in your pocket, it’s easy to stave off ennui. Learn about your ad choices: dovetail.prx.org/ad-choices

Sorry, But Speed Reading Won’t Help You Read More

The late Nora Ephron famously felt badly about her neck, but that's minor compared to how people feel about their reading. We think everyone else reads faster than we do, that we should be able to speed up, and that it would be a huge advantage if we could. You could read as much as a book critic for the New York Times. You could finish Infinite Jest. You could read all of Wikipedia. Learn about your ad choices: dovetail.prx.org/ad-choices

It’s Time to Stand Up for the Climate—and for Civilization

During his campaign for president, Donald Trump promised to end action on climate change and kill the climate treaty adopted in 2015 in Paris. To truly understand why that’s such a big deal—perhaps the biggest deal ever—you need to think about a few things. Yes, you need to think about the oft-repeated but nonetheless true and alarming statistics: 2014 was the hottest year ever recorded till 2015 snatched the crown—till 2016 obliterated the record.

Soft Robot Exosuits Will Give You Springier Steps

Robots are coming to take your jog. Or, at least, your walk. Each spring in your step costs your body calories. Robotic assistants could help ease fatigue for people who earn their living on their feet—or who have been hobbled by disease. But many robotic exoskeletons are so bulky that they actually cause wearers more fatigue. Learn about your ad choices: dovetail.prx.org/ad-choices

Physics Explains How (But Not Why) Humans Can Throw Washing Machines

Why would you throw a washing machine? Who knows. Maybe that machine lost your socks. Maybe you have something against washing machines. You could have any number of reasons. But here it is-a washing machine throwing contest, and even a world record distance for washing machine throws. (4.13 meters, Zydrunas Savickas.)

Why It’s Impossible to Predict When That Giant Antarctic Ice Sheet Will Split

Over the past several months, scientists working in Antarctica have been watching—with a mixture of professional fascination and personal horror—a fissure growing in the continent’s fourth-largest ice shelf. Since last November, the crack has lengthened by some 90 miles. It has 13 miles more before it rends completely, and a chunk of ice the size of Delaware goes bobbing into the Weddell Sea.

Did LeBron James Flop? Here’s What Physics Says

This is one of my jobs. When there is something that happens, I have to do an analysis-the internetneeds me. In this case, it's a hit between Draymond Green and LeBron James. Was it a hit, or did LeBron flop? I'm not the judge, I'm just going to present evidence. Collisions When an object interacts with another object (with zero external forces), this is called a collision. Here are some important physics ideas about collisions.

The Man in the Zebra Suit Knows the Secret of the Stripes

At four in the morning, Tim Caro roused his colleagues. Bleary-eyed and grumbling, they followed him to the edge of the village, where the beasts were hiding. He sat them down in chairs, and after letting their eyes adjust for a minute, he asked them if they saw anything. And if so, would they please point where? Not real beasts.

Don’t You Dare Try to Teach Science Without Building Models

It's the start of a new semester, so I think now is a good time to talk about the nature of science. As a physics faculty member, I teach all sorts of classes. Some of those classes are for chemistry and physics majors and some classes are for non-science majors. Whatever class you teach, though, I think it's important to bring up a discussion of the nature of science. Learn about your ad choices: dovetail.prx.org/ad-choices

To Understand PTSD, Send Scientists to War

It started with a thumb into my eye socket as he tried to gouge out my eye. When he bit into my ear, the adrenaline flooding my veins masked the pain; I would not even realize my ear was gone till after the fight. Twenty years ago, in that dimly lit alley in Kent, Washington, as I walked into a ring of teenage onlookers to face off, my heart was pounding so hard my chest hurt. My vision narrowed—I could only see faces—and I felt sick in my gut. Learn about your ad choices: dovetail.prx.org/ad-choices

NASA’s Newest Robots Will Spy on Mysterious Lil Asteroids

NASA missions come packaged two ways. They’re either deep explorations of the familiar—STEREO’s focus on the sun, the International Space Station’s study of what microgravity does to the human body—or a trip to some crazy place no one has ever seen before. But still, any strange, distant object the agency targets will likely hold some clue about the origins of life. Humans are spacefaring narcissists that way.

The Mystery of Fast Radio Bursts Only Gets More Beautiful From Here

Billions of years ago, an unknown object sent a seriously bright burst of radio waves into space. They traveled across the universe, past galaxies and clouds of gas and who knows what else. And in 2012, the burst arrived at the Arecibo radio telescope when astronomers happened to be watching. They kept searching that same spot in the sky. In 2015, they found 16 additional flashes.

California’s Huge Storm Could Cause Disastrous Melting in the Mountains

California is having a notably wet winter. Since October, a succession of weather systems has greened the Golden State’s valleys, whitened its mountains, and washed its rivers and reservoirs in rippling blue-green. The state is currently between storms. The one that just ended was cold. It dropped snow as low as 2,500 feet in California’s highlands. The successor storm, expected to hit on Saturday, will be warmer—forecasters are calling for snow levels to rise up to 9,000 feet. Learn about your ad choices: dovetail.prx.org/ad-choices

SpaceX’s Year of Fiery Triumphs and Explosive Failure

Maybe 2016 wasn’t your year. Buck up, at least your $60 million dollar rocket bearing a $200 million dollar payload didn’t explode on the launchpad. Or, perhaps your year was great.

The Mysterious Virus That Could Cause Obesity

Randy is 62 years old and stands tall at six foot one. He grew up on a farm in Glasford, Illinois, in the 1950s. Randy was raised with the strong discipline of a farming family. From the time he was five, he would get out of bed at dawn, and before breakfast he’d put on his boots and jeans to milk cows, lift hay, and clean the chicken coops. Day in and out, no matter the weather or how he felt, Randy did his physically demanding chores. Learn about your ad choices: dovetail.prx.org/ad-choices

WIRED’s Guide to Turning Your Kids Into Masterful Makers

This should be an officially labeled time of the year. I suggest we call it Maker Time-it's that time after kids get out of school, but before all of the holiday festivities begin.

How Science Uncovered $80 Million of Fine Art Forgeries

Something was wrong with the Jackson Pollock. For one thing, 3-D images from a stereomicroscope revealed that the signature was traced with a needle—forged. And, working with a hyper-precise Raman microscope, a tool capable of analyzing sample areas as small as a thousandth of a millimeter across, Jamie Martin identified the presence of Red 170, a pigment that wasn’t widely available until decades after Pollock’s death.

Why Do Dogs Love Yoga Mats So Much?

You unfurl your yoga mat at home, ready to stretch out into downward dog and take some deep breaths. Just for a second, you look away to grab your water bottle and block.

Thousands of Invisible Oil Spills Are Destroying The Gulf

Hurricane Ivan would not die. After traveling across the Atlantic Ocean, it stewed for more than a week in the Caribbean, fluctuating between a Category 3 and 5 storm while battering Jamaica, Cuba, and other vulnerable islands. And as it approached the US Gulf Coast, it stirred up a massive mud slide on the sea floor. The mudslide created leaks in 25 undersea oil wells, snarled the pipelines leading from the wells to a nearby oil platform, and brought the platform down on top of all of it.

Why Japan’s 6.9 Quake Wasn’t 2011 All Over Again

Sequels rarely live up to the original. And thank goodness for that. Yesterday, a 6.9 earthquake shook the coast of Japan almost exactly where a 9.1 quake hit nearly 6 years ago. Japan is fortified against quakes and tsunamis. But the 2011 quake was so powerful it generated 30 to 60-foot tsunamis, overtopping the island nation's extensive sea walls and shore protections, killing over 15,000, leaving 228,000 homeless, and causing a meltdown at the Fukushima Daiichi nuclear plant.
