Take a Good Look, America. This Is What the Reckoning Looks Like
Editor’s note: This is a developing story about California’s Camp Fire and Woolsey Fire. We will update it as more information becomes available. By at least one metric, we humans are dumber than frogs. The fable goes that if you toss a frog in a pot of hot water, it’ll leap right out. Put it in cold water, though, and bring it slowly to a boil, and the frog won’t notice before it’s too late. That turns out to be a myth—frogs are smarter than that.

The Risk That Ebola Will Spread to Uganda Is Now ‘Very High’
Ebola is one of those scourges where the mere mention of its name strikes fear: the virus, which kills about half of those it infects and gets passed on through body fluids, is notoriously hard to contain. Because of its long incubation period, healthy-looking people can spread the deadly disease for weeks before symptoms appear. Learn about your ad choices: dovetail.prx.org/ad-choices

These Wind Patterns Explain Why California's Wildfires Are So Bad
Editor’s note: This is a developing story about California’s Camp Fire, Hill Fire, and Woolsey Fire. We will update it as more information becomes available. In California three major fires—the Camp Fire in the north and Hill Fire and Woolsey Fire in the south—continue to rage on a scale the state has never seen before.

The Terrifying Science Behind California’s Massive Camp Fire
Editor’s note: This is a developing story about California’s Camp Fire, Hill Fire, and Woolsey Fire. We will update it as more information becomes available. At 6:30 Thursday morning, a wildfire of astounding proportions and speed broke out in Northern California. Dubbed the Camp Fire, it covered 11 miles in its first 11 hours of life. A mile an hour might not seem fast in human terms, but it’s an extreme rate of speed as far as fires are concerned. Learn about your ad choices: dovetail.prx.org/ad-choices

Don’t Want to Fall for Fake News? Don’t Be Lazy
On Wednesday night, White House press secretary Sarah Huckabee Sanders shared an altered video of a press briefing with Donald Trump, in which CNN reporter Jim Acosta's hand makes brief contact with the arm of a White House Intern. The clip is of low quality and edited to dramatize the original footage; it's presented out of context, without sound, at slow speed with a close-crop zoom, and contains additional frames that appear to emphasize Acosta's contact with the intern.

A New Robot Tracks Sick Bees Wearing Tiny Coded Backpacks
Science hasn’t been giving us a tremendous amount of good news these days. We’re speeding toward climate catastrophe, for one. We’ve screwed up the environment so badly, it’s hard to even call it an environment anymore. And that’s coming back to bite (or sting) us: Bee populations, which we rely on to pollinate our crops, are plummeting. Learn about your ad choices: dovetail.prx.org/ad-choices

Weed Wins on Election Day. So What Comes Next?
And so a few more dominoes fall. Michigan voted to legalize the recreational use of cannabis, while Utah and Missouri legalized it for medical use, according to projections made late Tuesday night. (A recreational measure in North Dakota failed, though medical cannabis remains legal there.) They join 31 other states that have already gone the medical route, and nine others that have gone fully recreational. Learn about your ad choices: dovetail.prx.org/ad-choices

THC! CBD! Terpenoids! Cannabis Science Is Getting Hairy
Today, cannabis continues its slow march toward nationwide decriminalization with voters deciding whether to allow recreational use in Michigan and North Dakota, and for medical purposes in Utah and Missouri. As states keep chipping away at federal prohibition, more consumers will gain access, sure—but so will more researchers who can more easily study this astonishingly complex and still mysterious plant.

New Satellites Will Use Radio Waves to Spy on Ships and Planes
When a company called HawkEye360 wanted to test its wares, it gave an employee a strange, deceptive task. While the worker stood in Virginia, he held the kind of transceiver that ships carry to broadcast their GPS locations. Usually such a signal would reveal his true position to a radio receiver, but he’d altered the broadcast to spoof his GPS position, making it seem like he was in fact off the coast of Maine.

The Key to a Long Life Has Little to Do With ‘Good Genes’
In 2013, Google cofounder and CEO Larry Page announced the formation of a new Alphabet entity dedicated to solving the pesky puzzle of mortality. Since then, the billion-dollar longevity lab known as Calico—short for California Life Company—has been trying to tease apart the fundamental biology of aging in the hopes of one day defeating death.

The Breakthrough Prizes Have Money, but They Need Diversity Too
The Breakthrough Prizes are unlike anything else in science. Instead of the hum of lab equipment, there’s Orlando Bloom. Instead of donning lab coats, the scientists find themselves marching down a red carpet in their black-tie best. Learn about your ad choices: dovetail.prx.org/ad-choices

Bitcoin Will Burn the Planet Down. The Question: How Fast?
Max Krause was thinking of buying some bitcoin, as one does. But Krause is an engineer—mostly he works on modeling greenhouse gas emissions from landfills—so his first step was to run the numbers. He looked at price, of course, but also how fast the world’s bitcoin miners create new bitcoins and the ledger that accounts for them. And he looked at how much electricity that would seem to require. “I thought, man, this is a lot of energy,” Krause says. Learn about your ad choices: dovetail.prx.org/ad-choices

How Antivax PACs Helped Shape Midterm Ballots
In early 2015, Sen. Ervin Yen, an anaesthesiologist who became Oklahoma’s first Asian American state legislator, introduced a bill to require all schoolchildren to be vaccinated, unless they had a medical reason not to. California had recently debuted similar legislation after an outbreak of measles in Disneyland sickened 147 people and led to the quarantine of more than 500 others.

Quantum Physicists Found a New, Safer Way to Navigate
In 2015, the U.S. Naval Academy decided that its graduates needed to return to the past and learn how to navigate using the stars. Nine years prior, it had dropped celestial navigation from its requirements because GPS was so accurate and simple to use. But recent events had shaken the academy’s faith in GPS. Researchers had taken over a yacht’s navigation system as it steered in the Mediterranean. Learn about your ad choices: dovetail.prx.org/ad-choices

The ISS Has a Supercomputer! Never Mind the Fried Disks
One year ago, Hewlett Packard Enterprise sent an off-the-shelf supercomputer up to the International Space Station, to see if its mass-produced hardware could survive, basically unmodified, in the harsh environment of space. Now NASA and the computer company are declaring the experiment a success—even though nearly half of its hard disks failed after getting fried by solar radiation.

The Sea May Be Absorbing Way More Heat Than We Thought
If you ever meet a climate scientist, give them a hug. Not only is the work important, it involves an absolute mess of variables—emissions, maybe sequestering those emissions, atmospheric patterns, maybe geoengineering that atmosphere. Data is often sparse or non-existent. So give them a hug. The data problem is particularly acute in the oceans. A key part of figuring out how much the planet has warmed, and how drastically we need to cut emissions, is determining how the sea is changing.

Apple's Heart Study Is the Biggest Ever, But With a Catch
Last November, Apple Watch owners began receiving recruitment emails from Apple. The company was looking for owners of its smartwatch to participate in the Apple Heart Study—a Stanford-led investigation into the wearable's ability to sense irregular heart rhythms. Joining was simple: Install an app and wear your watch. Learn about your ad choices: dovetail.prx.org/ad-choices

Calling the Caravan's Migrants "Diseased" Is a Classic Xenophobic Move
It would be extraordinarily difficult—impossibly difficult—for any one of the several thousand asylum-seeking refugees in the so-called migrant caravan now on the border between Guatemala and Mexico to have smallpox. A global vaccination campaign eliminated the disease from the world at large in 1980. Yet that’s what a guest on the Fox Business Network show Lou Dobbs Tonight said earlier this week.

Los Angeles Must Pay Billions to Adapt—or Slip Into the Sea
Los Angeles derives much of its charm from its diversity, both of its people and its amenities—rolling hills here, lovely architecture there, a national forest to the north and legendary beaches to the west. But much of it is in trouble: Sea level rise is coming for Los Angeles County and its 74 miles of coast. According to a new report from the New York Academy of Sciences, it’ll take LA as much as $6.

A New Climate Change Lawsuit Takes Aim at ExxonMobil
This story originally appeared in the Guardian and is part of the Climate Desk collaboration. New York is suing the oil giant ExxonMobil in a lawsuit that claims the company engaged in a “longstanding fraudulent scheme” to downplay the risks posed to its business by climate change regulations.

Does Climate Change Mean You Should Fly Less? Yeah, Maybe
This story originally appeared on Slate and is part of the Climate Desk collaboration. Two weeks ago, the Intergovernmental Panel on Climate Change released a dire report that made crystal clear that we have about a decade to stop catastrophic levels of climate change. The report caught fire for another extremely near deadline: It suggests that if we don’t manage to dramatically shift carbon emissions, we’ll start feeling the brunt of the effects as soon as 2040.

Carbon Capture Is Messy and Fraught—But Might Be Essential
On paper, carbon capture is a simple proposition: Take carbon that we’ve pulled out of the Earth in the form of coal and oil and put into the atmosphere, and pull it out of the atmosphere and put it back in the Earth. It’s like hitting undo on the Industrial Revolution. And scientists can indeed yank CO2 out of thin air, except that the process is expensive, not very efficient, and morally complicated.

The Science of the Sniff: Why Dogs Are Great Disease Detectors
In November 2016, a team of scientists from the Medical Research Council in Gambia visited primary schools armed with hundreds of beige-colored nylon socks. Handing them out to children there aged five to 14, the researchers instructed them to wear the socks overnight, only taking them off if they were washing their feet for prayer.

How Trick-or-Treaters Can Stay Visible on a Dark and Spooooky Night
When I think of Halloween, I think of kids outside in the dark. Traditionally, this is the way it works. First, darkness makes everything just a little bit spookier and more Halloween-like. Second, the end of October used to be after the end of Daylight Savings Time such that it would get dark earlier. Of course this year, Daylight Savings Time doesn't end until November 4. However, let's assume it's dark. Kids running around in the dark on streets with cars can lead to bad things. Learn about your ad choices: dovetail.prx.org/ad-choices

Water, Flour, Syrup, Dye: Mastering the Elements of Fake Blood
The internet is oozing (dripping? spurting?) with recipes for fake blood, but to get the exact color and consistency your Halloween costume calls for—be it bright and wet or dark and crusty—your best bet is to brew your own bloody concoction. To do it, it helps to know the properties of blood that you're approximating and the non-biohazardous ingredients you can use to imitate them.

Ginkgo Bioworks Is Turning Human Cells Into On-Demand Factories
From the windows of Ginkgo Bioworks’ Boston offices you can peer down into a grimy vestige of the city’s past. Across the street, workers in yellow-slicker overalls scrub, scrape, and repair the decks of worn-out warships and ocean tankers parked in a drydock. During World War II, 50,000 people worked the docks and the eight-story waterside warehouse that Ginkgo now calls home. Learn about your ad choices: dovetail.prx.org/ad-choices

An Ebola Outbreak in a War Zone Is About as Bad as It Gets
In July, a 65-year-old woman running a high fever checked into a hospital in the province of North Kivu, along the Democratic Republic of Congo’s border with Uganda. She was later discharged and returned home to her remote town, only to die a few days later. By the time health officials checked in on the case, seven members of her immediate family had also died the violent, bloody deaths that can usually only mean one thing: Ebola. Normally, this wouldn’t be reason to panic. Learn about your ad choices: dovetail.prx.org/ad-choices

These Wasp-Like Drones Lift Heavy Loads With Their Bellies
You might know wasps for their ability to brainwash cockroaches or inflict one of the most painful stings on Earth—one so powerful that the actual scientific advice to victims is to just lie down and scream until it passes. Lesser-known is the wasp’s superlative ability to carry loads that are unexpectedly heavy given the creature’s size. Small drones, or “micro air vehicles,” are only able to lift the equivalent of their own weight. Learn about your ad choices: dovetail.prx.org/ad-choices

Fusty Ol' Scientific Texts Get a Gorgeous, Pricey Makeover
Alexander von Humboldt began his working life as a mine inspector for the Prussian government. But in his late twenties, he left his government gig and set off to explore Venezuela, Cuba, Mexico, Colombia, and Peru with botanist Aime Bonpland. He did an astounding amount of work during his travels, in pursuit of his hypothesis that “all forces of nature are interlaced and interwoven”—and that, maybe, he could figure out how.

3 Smart Things About Animal-Inspired Robotics
1. When turkeys strut, their leg muscles work as shock absorbers to boost energy efficiency. That gam action inspired a prosthetic exoskeleton for humans: The lightweight contraption is outfitted with a spring and clutch that take the impact off the user’s calf muscle. In experiments, a person wearing the braces while walking expended 10 percent less energy. 2. Though it has a brain, the lamprey—an eel-like beast—doesn’t need it to wiggle about the deep.

Science Isn't About 'the Truth'—It's About Building Models
You might think you can just leave the science stuff to scientists—but you can't. We live in a world that is surrounded by science and we use toys that depend on science (like that fancy smartphone in your hand). Other issues, like climate change and vaccinations, can have a significant impact on any one of us. You don't have to be science nerd, but you have to at least know the important parts of science.

Scientists Help Robots 'Evolve.' Weirdness Ensues
Evolution is a trip. On the one hand, it’s a seemingly simple mechanism—those best fitted to their environment have more babies, while less fit individuals don’t reproduce as much, and their genes filter out of the system. But on the other hand (or paw or claw or talon), it has given rise to an astounding array of organisms. Some animals fly with feathered wings, others with membranes stretched between fingers. Some run on two legs, others four. Learn about your ad choices: dovetail.prx.org/ad-choices

DNA Tests Could Help Docs Detect Infectious Diseases Faster
Early last spring, as flu season hit its peak, a woman checked into a Houston hospital with all the familiar symptoms: fever, headache, a grating cough. A chest x-ray revealed an infection engulfing her lungs. Doctors hooked her up to an antibiotic drip, collected blood to be processed and cultured in the hospital’s lab, and shipped one of the tubes overnight to a small, stealthy startup in Redwood City, California, called Karius.

Funky Materials Give the Mantis Shrimp Its Powerful Punch
Imagine for a second that you’re a crab, and a fellow crustacean called a mantis shrimp has decided to make you its lunch. The truth is, it’s not worth struggling. The mantis shrimp uses muscles to cock back two hammer-like appendages under its face, storing energy in a saddle-like divot in the limbs. Learn about your ad choices: dovetail.prx.org/ad-choices

An App Built for Hurricane Harvey Is Now Saving Lives in Florida
Last Wednesday, Hurricane Michael slammed into the Florida Panhandle at 155 miles per hour, flattening neighborhoods, turning subdivisions into rubble, and plunging the coast into darkness. On Friday, Trevor Lewis packed up two trucks with crowbars, chainsaws, sledgehammers, ropes, walkie talkies, and five other guys from Cocoa Beach, where he lives on the east side of the state. As night fell they began the drive up into the worst of the wreckage. Learn about your ad choices: dovetail.prx.org/ad-choices

Life-Saving Deliveries Will Get Drones Flying the Skies
Delivery drones are real and they’re operating on a national level, but they’re not dropping off impulse purchases, and some of the most important applications are not in the United States. Zipline, a Bay Area startup, inked a deal with the government of Rwanda in 2016 and now uses small, autonomous planes to deliver medical supplies, and in particular blood, to rural communities across the African country.

Big Data and the End of Painful, Invasive Medical Procedures
You heard it here first, folks; Stephen Quake is coming for the colonoscopy. The scientist has made a career of replacing invasive, painful, and dangerous procedures with simple, cheap tests that can be performed almost anywhere. Just this year, a blood panel he developed to detect genetic birth defects has been taken by more than three million women, replacing the need for amniocentesis and giant, uterus-puncturing needles.

So Much Genetic Testing. So Few People to Explain It to You
When Dan Riconda graduated with a master’s degree in genetic counseling from Sarah Lawrence College in 1988, the Human Genome Project was in its very first year, DNA evidence was just beginning to enter the courts, and genetic health tests weren’t yet on the market. He found one of the few jobs doing fetal diagnostics for rare diseases, which often meant helping young families through the worst time in their lives. What a difference 20 years makes.

Here's What Astronauts See When a Rocket Aborts Mid-Flight
Nick Hague spent 20 years dreaming of getting into space, first as an Air Force test pilot, then as a NASA astronaut since 2013. He got his big chance to blast into orbit last Friday aboard a Soyuz spacecraft launching from Russia’s Baikonur Cosmodrome in Kazakhstan. Hague and Russian cosmonaut Aleksey Ovchinin were expecting a routine six-hour flight to the International Space Station, but two minutes after liftoff, something went wrong.

Silicon Valley’s Tech Elite Zoom in on Crispr
Three hundred and sixty four days ago, Jiwoo Lee’s friends helped her celebrate her 18th birthday by baking her a Rice Crispr cake. They bedecked the gooey, cereal-based treat with blue and red frosted double helixes in honor of her favorite high school hobby—gene editing. Lee, who won top awards at the 2016 Intel International Science and Engineering Fair, is one of the youngest champions of the “Crisprize everything!” brigade.

You’re Expecting Too Much Out of Boston Dynamics’ Robots
At the WIRED25 festival in San Francisco Sunday evening, Boston Dynamics’ SpotMini robot got onstage and did what no other quadruped robot has done before: It danced the running man like it was born to. It was a bit more, well, robotic than a human, but it illustrated just how far Spot has come: Twenty-five years into both WIRED’s and Boston Dynamics’ lives, robots have finally grown sophisticated enough to dance through our world. And a lot more than that, of course. Learn about your ad choices: dovetail.prx.org/ad-choices

Boston Dynamics Is Prepping Its Robot Dog to Get a Job
Late last night Boston Dynamics dropped a new video of its robot dog, SpotMini, in action. It walks up some stairs (no big deal—it’s done that before) and then through some corridors, periodically extending its camera-equipped arm to survey bits of a construction site. Then it walks backwards down some stairs and through a doorway and then … Fade to black. Learn about your ad choices: dovetail.prx.org/ad-choices

Genome Hackers Show No One’s DNA Is Anonymous Anymore
In 2013, a young computational biologist named Yaniv Erlich shocked the research world by showing it was possible to unmask the identities of people listed in anonymous genetic databases using only an Internet connection. Policymakers responded by restricting access to pools of anonymized biomedical genetic data. An NIH official said at the time, “The chances of this happening for most people are small, but they’re not zero. Learn about your ad choices: dovetail.prx.org/ad-choices

The Quest to Make California’s Weed the Champagne of Cannabis
What’s in a name? For champagne, it’s the expectation of excellence and at the very least, bubbles. It’s even protected by law: To call a liquid champagne, you have to grow it in a certain part of France under certain rules of planting, pressing and even packaging. All the fuss means champagne makers can charge a premium for their product. The same may soon be true for Northern California’s legendary weed.

How Hurricane Michael Got Super Big, Super Fast
Michael introduced itself to North America with 155-mile-per-hour gusts of wind and a barometric pressure of 919 millibars, the third-strongest hurricane to ever make continental US landfall. It was a monster, and it stayed a monster as it rolled through Georgia and then on toward the Carolinas. And monsters are made, not born. Learn about your ad choices: dovetail.prx.org/ad-choices

A Long Goodbye to Baxter, a Gentle Giant Among Robots
For a serious research robot, Baxter is a charmer. It’s sports-car red, with two big and deliberate arms. Its face is a flat screen that telegraphs “feelings” like embarrassment (rosy cheeks, upturned eyebrows). If you’re so inclined, you can sit in front of it and make it read your mind to fix its mistakes. Or you can point to objects for it to pick up.

Physicists Condemn Sexism Through ‘Particles for Justice’
This week, of all weeks, should have been triumphant for women in physics. For her work on lasers, Canadian physicist Donna Strickland became the first female Nobel Laureate for the field after 55 years. She finally joined a short list consisting of just two other women, Marie Curie and Maria Goeppert-Mayer. But Seyda Ipek barely had time to celebrate. The University of California, Irvine physicist was preoccupied: a dumpster fire had just erupted in a neighboring corner of physics culture. Learn about your ad choices: dovetail.prx.org/ad-choices

Bionic Limbs 'Learn' to Open a Beer
Andrew Rubin sits with a Surface tablet, watching a white skeletal hand open and close on its screen. Rubin’s right hand was amputated a year ago, but he follows these motions with a special device fitted to his upper arm. Electrodes on his arm connect to a box that records the patterns of nerve signals firing, allowing Rubin to train a prosthetic limb to act like a real hand. “When I think of closing a hand, it’s going to contract certain muscles in my forearm,” he says.
