The Controversial Link Between Epic Storms and a Warming Arctic

It’s that time of the year again, when massive winter storms lash the eastern United States and your uncle posts on Facebook about how it proves climate change is a hoax. After all, why would you still need a good coat on a warming planet? The fallacy is, of course, that weather is not the same as climate—though the two are intertwined in sometimes surprising ways.

Please Stop Building Houses Exactly Where Wildfires Start

Built well, a city should provide a bulwark against disaster. Fundamentally, all cities are fortresses. Or at least they should be. If a city is a fortress, where’s the wall? The edges of North American cities today aren’t edge-like at all. Most of them, especially in the West, ooze outward in a gradient, urban to suburban to exurban to rural to wild.

The Physics of the Speeder Chase in Solo: A Star Wars Story

I make it my job to hunt through all the best trailers and find some cool physics thing to explore. In this case, it's the trailer for Solo: A Star Wars Story—the Han Solo-led movie, scheduled to come out in May, that takes place some time before Episode IV: A New Hope. Right at the beginning, we see Han driving some type of speeder in a chase scene, taking a super-sharp turn with another speeder in pursuit. Learn about your ad choices: dovetail.prx.org/ad-choices

Can Machine Learning Find Medical Meaning in a Mess of Genes?

“We don’t have much ground truth in biology.” According to Barbara Engelhardt, a computer scientist at Princeton University, that’s just one of the many challenges that researchers face when trying to prime traditional machine-learning methods to analyze genomic data.

The Transformer of Autonomous Farmbots Can Do 100 Jobs on Its Own

The first fully autonomous ground vehicles hitting the market aren’t cars or delivery trucks—they’re ­robo­-farmhands. The Dot Power Platform is a prime example of an explosion in advanced agricultural technology, which Goldman Sachs predicts will raise crop yields 70 percent by 2050. But Dot isn’t just a tractor that can drive without a human for backup. Learn about your ad choices: dovetail.prx.org/ad-choices

No Refrigeration Necessary: New Tech for Everlasting Shelf-Life

There’s hope for a tastier, healthier, more robust tomorrow: high-tech new food preservation methods that fend off the bad stuff (bacteria, spoilage) while protecting the good (flavor, texture, nutrients). Scientists are experimenting with everything from microwave sterilization to blasts of plasma to ensure food stays appetizing longer—even without refrigeration.

Can Humans Survive on Water Vapor Alone?

The world is full of water, flushing down our toilets and flowing from our taps. And yet where I live, in the American Southwest, and quite possibly where you live, the kind of water people need to survive is getting harder to come by. Across the region, temperatures are rising and droughts are getting more severe, and in the coming decades the West will struggle to supply the water its residents and businesses demand.

Apparently We Can Let the Stock Market Fight Climate Change

Fixing the effects of climate change on Earth isn’t complicated. When you get down to it, all we humans need to save the world is ingenuity, grit, cooperation, and $53 trillion. Where is humanity supposed to come up with that kind of cash at this time of night? The International Energy Agency says Earth needs those trillions invested in energy supply and efficiency by 2035 to keep global warming below 2 degrees C.

Sea Level Rise in the SF Bay Area Just Got a Lot More Dire

If you move to the San Francisco Bay Area, prepare to pay some of the most exorbitant home prices on the planet. Also, prepare for the fact that someday, your new home could be under water—and not just financially. Sea level rise threatens to wipe out swaths of the Bay's densely populated coastlines, and a new study out today in Science Advances paints an even more dire scenario: The coastal land is also sinking, making a rising sea that much more precarious.

The CDC Can't Fund Gun Research. What if that Changed?

America doesn't have good data on guns. Blame the Dickey amendment. First introduced in 1996, the legislation didn't ban gun investigations explicitly (it forbade the use of federal dollars in the advocacy or promotion of gun control), but Congress that year also cut the budget for the Centers for Disease Control and Prevention by the exact amount it had previously devoted to firearm research. It's had a chilling effect on the field ever since. Learn about your ad choices: dovetail.prx.org/ad-choices

Researchers Used This Genealogy Site to Build a 13 Million-Person Family Tree

In the last 20 years, genealogy websites have attracted more than 15 million customers by promising insights into your past. Maybe you’ll uncover a secret infidelity or be reunited with a long-lost cousin, like when Larry met Bernie on Finding Your Roots. It’s deeply personal, affecting stuff. But when your family tree contains thousands, millions, even tens of millions of people, it’s no longer a personal history. It’s human history.

The Secret to a High Tech Concierge Medical Office? Data

By design, the downtown San Francisco storefront offices of Forward feel more like a spa or a ritzy skin care boutique than a doctors’ office. But the latter thing is true. Despite the sun shining through floor-to-ceiling windows onto pastel walls, blond-wood surfaces and no check-in desk in sight (attractive, casually dressed receptionists with iPads offer you a water), Forward is a concierge medical service.

Spoof, Jam, Destroy: Why We Need a Backup for GPS

Earth got a warning shot on January 25, 2016. On that day, Air Force engineers were scheduled to kill off a GPS satellite named SVN-23—the oldest in the navigation constellation. SVN-23 should have just gone to rest in peace. But when engineers took it offline, its disappearance triggered, according to the National Institute of Standards and Technology, a software bug that left the timing of some of the remaining GPS satellites—15 of them—off by 13.7 microseconds.

How Flight Simulation Tech Can Help Turn Robots Into Surgeons

The robotic platform heaves, as if breathing. Atop it stretches a piece of white gauze with a blue line painted down the middle. Along this line another robot snips with little surgical scissors, waiting for the platform to come to a brief rest before making a cut. And another snip, and rest. And another, and rest, on down the line. This could be you one day. Not that you’ll turn into a robot—you may go under the knife of a machine working as a surgical assistant.

You Can Find the Gravitational Constant with String and a Mountain

There are quite a few fundamental constants. These are things like the speed of light (c) the charge on an electron (e), and the Planck constant (h). These constants are determined with some type of interesting experiment. The first values of these constants were often difficult to find—the speed of light, for example, was calculated by tracking the moons of Jupiter. Of course, now we have much better methods to get a very precise value for the speed of light. Learn about your ad choices: dovetail.prx.org/ad-choices

How to Build a Space Communication System Out of Lasers

In October 2013, a moon-orbiting NASA spacecraft aimed a laser beam at Earth, 239,000 miles away. Within seconds, the intended recipient—an observatory in southern California—locked onto the beam of infrared light, invisible to the naked eye. Encoded inside the light was a high-definition video of NASA administrator Charles Bolden delivering a short speech. Bolden had, of course, recorded the video on Earth.

Why It's So Hard to Dose Weed

Cannabis is a notoriously finicky drug. Take the right amount and you get relaxation or euphoria, but take too much and it’s a long ride of paranoia.

Inside Robert Bigelow's Decades-Long Obsession With UFOs

In 1994, a Mormon family bought a 480-acre plot in in Utah’s Uintah Basin, thinking they’d get back to the land. But this particular land was weird. It came with too-large-thrice-over wolves that refused to die by bullet, cattle with their reproductive organs sucked clean out, and a multitude of UFOs, as they told the Deseret News in 1996. It was driving them bonkers. Robert Bigelow saw their story. Learn about your ad choices: dovetail.prx.org/ad-choices

The Ongoing Battle Between Quantum and Classical Computers

A popular misconception is that the potential—and the limits—of quantum computing must come from hardware. In the digital age, we’ve gotten used to marking advances in clock speed and memory. Likewise, the 50-qubit quantum machines now coming online from the likes of Intel and IBM have inspired predictions that we are nearing “quantum supremacy”—a nebulous frontier where quantum computers begin to do things beyond the ability of classical machines.

Winter Olympics 2018: The Physics of Blazing Fast Bobsled Runs

I don't know very much about bobsleds—but I know quite a bit about physics. Here is my very brief summary of the bobsled event in the winter Olympics. Some humans get in a sled. The sled goes down an incline that is covered in ice. The humans need to do two things: push really fast to get the thing going and turn to travel through the course. But from a physics perspective, it's a block sliding down an incline. Just like in your introductory physics course. Learn about your ad choices: dovetail.prx.org/ad-choices

I’m relatively certain they weren’t talking about snow, but let’s pretend they were anyway: Global warming threatens to wreak havoc on snowpack. The American west in particular already has a snowpack problem, which means less water for drinking and powering hydroelectric plants. Unfortunately you can’t just force snow to fall out of the air.

LED Flashlights Are Bright—But Just How Bright, Exactly?

It seems like I have been slightly obsessed with flashlights for quite some time. Perhaps it started when the Maglite lights became popular in the '80s.

How Ice Skaters Turn Physics Into Astonishing Spins

Many people don't know too much about angular momentum—and that's fine. But what about figure skaters? Whether they understand the concept of angular momentum doesn't matter but they use it in one of the all time classic skating moves. You've seen it before. The skater starts off in a standing position and spins about the vertical axis. After a few rotations, the skater pulls both arm in closer to the body and spins faster. In physics, we call this conservation of angular momentum. Learn about your ad choices: dovetail.prx.org/ad-choices
