For the dozen years between 1974 and 1986, he rained down terror across the state of California. He went by many names: the East Side Rapist, the Visalia Ransacker, the Original Night Stalker, the Golden State Killer. And on Wednesday, law enforcement officials announced they think they finally have his real name: Joseph James DeAngelo. Police arrested the 72-year-old Tuesday; he’s accused of comm...

For the first time since launching the Curiosity rover in 2011, NASA is sending a spacecraft to the surface of Mars. Exciting! Surface missions are sexy missions: Everyone loves roving robots and panoramic imagery of other worlds. But the agency's latest interplanetary emissary won't be doing any traveling (it's a lander, not a rover). And while it might snap some pictures of dreamy Martian vistas...

When I ask Bradley Worthington to tell me about that one time people in the southwest thought his trucking company, McCollister's, was moving a UFO across the country, he laughs. There’s not a “that one time.” “It happens frequently,” he says, “especially with oversized things.” And McCollister's hauls a lot of oversized things. Learn more about your ad choices.

The year 2004 was a simpler time to be an infectious disease doctor in the US. Zika and chikungunya hadn’t yet emerged. Mystery RNA viruses weren’t spreading by tick bite around America’s heartland, killing farmers and ranchers. Certainly no one was on the lookout for a meat allergy caused by a tick with a white splotch on its back the shape of Texas. But that was then. Learn more about your ad ch...

On a breezy evening this past weekend, I sat out on my patio, lit a sizable joint, and took little drags from it til the burn line singed my fingertips. When I stood up I was stoned, and I knew it; I rarely smoke pot, so when I do I really feel it. But how high was I, really? I reached for my phone, logged into an app called Druid, and took a five minute test. When I finished it gave me my results...

“Siri, where is the nearest Starbucks?” “Alexa, order me an Uber.” “Suki, let’s get Mr. Jones a two-week run of clarithromycin and schedule him back here for a follow-up in two weeks.” Doesn’t sound that crazy, does it? For years, voice assistants have been changing the way people shop, get around, and manage their home entertainment systems. Now they’re starting to show up someplace even a little...

This storyoriginally appeared on Undarkand is part of theClimate Deskcollaboration. On March 23, 1971, the Soviet Union set off three Hiroshima-scale nuclear blasts deep underground in a remote region some 1,000 miles east of Moscow, ripping a massive crater in the earth. The goal was to demonstrate that nuclear explosions could be used to dig a canal connecting two rivers, altering their directio...

The tsunami-driven seawater that engulfed Japan’s Fukushima Daiichi nuclear plant has long since receded. But plant officials are still struggling to cope with another dangerous flood: the enormous amounts of radioactive water the crippled facility generates each day. More than 1 million tons of radiation-laced water is already being kept on-site in an ever-expanding forest of hundreds of hulking...

It's hard not to like BattleBots. It is essentially a modern technology-based sporting event in which teams build remote controlled robot-like things that fight in an arena. Two robots enter, one robot leaves—and on May 11, the eighth season of the showdown begins. Of course, there are many engineering aspects of these bots—but underlying every bit of technological terror is some very fundamental...

The main act of Kang-Kuen Ni’s experiment could fit on the tip of a needle—and it happens in a fraction of a second. The Harvard chemist takes two individual atoms, a sodium and a cesium, each about 10,000 times smaller than a bacterium. Then, very carefully, she brings them together to become a single molecule: sodium cesium. It’s an unlikely pairing. Learn more about your ad choices. Visit podca...

In 2011, biologists Jennifer Doudna and Emmanuelle Charpentier published a landmark paper introducing the world to Crispr. The arcane family of bacterial proteins had a talent for precisely snipping DNA, and one of them—Cas9—has since inspired a billion-dollar boom in biotech investment. Clinical trials using Cas9 clippers to fix genetic defects are just beginning, so it will be years before Crisp...

Benefits of robots: 1. They never get tired. 2. They can lift very heavy things. 3. They can walk through (controlled) conflagrations on college campuses. At least, that is, the robots in and around roboticist Jessy Grizzle’s lab at the University of Michigan. Specifically, Grizzle is working with a remote-controlled biped called Cassie, a research platform that roboticists are using to master bip...

This storyoriginally appeared on CityLaband is part of theClimate Deskcollaboration. Over the years, John Zimmer, the co-founder and president of Lyft, has often pointed to a class he took as an undergraduate as the source of his ideas about environmental sustainability—and by extension, Lyft’s goals to create greener transportation options. The class at Cornell University was called “Green Cities...

Kay Dickersin knew she was leaping to the front lines of scholarly publication when she joined The Online Journal of Current Clinical Trials. Scientific print-publishing was—and still is—slow and cumbersome, and reading its results sometimes required researchers to go to the library. But as associate editor at this electronic peer-reviewed journal—one of the very first, launched in the summer of 1...

Self-driving cars have it rough. They have to detect the world around them in fine detail, learn to recognize signals, and avoid running over pets. But hey, at least they’ll spend most of their time dealing with other robot cars, not people. Now, a delivery robot, on the other hand, it roams sidewalks. That means interacting with people—lots of people—and dogs and trash and pigeons. Unlike a road,...

And then the lights went out. Again. The loss of electrical power in Puerto Rico and the US Virgin Islands after Hurricane Maria churned across the islands in September 2017 was already the second-biggest blackout in the history of power on Earth—3.4 billion lost customer-hours. But in recent weeks, various agencies were touting their success in restoring Puerto Rico’s flattened grid. Learn more a...

In December 1861, as a California drought was wearing into its fifth year, farmers on the West Coast were all asking for one thing for Christmas: rain. And boy did they get it. For 43 days rain and snow fell across the state, causing rivers to surge their banks, turning the 300-mile long, 20-mile-wide Central Valley into an ice-cold inland sea. LA got 66 inches. So deep were Sacramento’s floodwate...

You know two-factor authentication tokens, the ephemeral, six-digit numbers you use as a second layer of security when logging into, say, your email? Those constantly updating, randomly generated numbers are one of the easiest ways to protect your accounts from being hacked. But for some time now, I've harbored a pet conspiracy theory about those codes: Maybe they aren't as random as we're led to...

Yesterday morning a tall, lanky 16-year-old boy in a red polo shirt stood at a podium in front of a roomful of doctors, scientists, and regulators and told them about how a drug they were considering for approval had changed his life. “I had seizures for 10 years,” he said. “My parents tell me there were times I had seizures 100 times a day.” Now, he said, he has been seizure free for nearly two a...

Almost exactly a year ago, 23andMe earned the right to tell people what diseases might be lurking in their DNA. Since then, the consumer genetic testing company has turned tubes of spit into health reports for thousands of its customers. You can learn how your genes might predispose you to eight diseases with a well-known genetic component—things like Parkinson’s, Alzheimer’s, and most recently, b...

The only thing I know about the Freeze is that no one can beat the Freeze (except with a generous head start). And he's awesome. In case you haven't seen, the Freeze is this guy in a turquoise spandex suit that challenges mere mortals to a race in the outfield of the Atlanta Braves SunTrust Park between innings. Overall, this seems like a great physics problem. Learn more about your ad choices. Vi...

Employees arriving at the Peninsula’s newest, shiniest corporate campus will find it equipped with all the creature comforts now expected in Silicon Valley. There are gaming consoles with stadium-level seating; a tricked-out gym where trainers both real and virtual will kick your butt into shape; well-sod grounds where you can walk off your local, vegan, carb-free lunch or work wirelessly in the w...

And just like that, humanity draws one step closer to the singularity, the moment when the machines grow so advanced that humans become obsolete: A robot has learned to autonomously assemble an Ikea chair without throwing anything or cursing the family dog.

In a bright warehouse in the heart of Northern California’s cannabis country, a metal gate slowly peels up. “Also Sprach Zarathustra”—the iconic music from 2001: A Space Odyssey—blares as the room behind is revealed. A mob of marijuana farmers and local politicians and activists and venture capitalists shuffle through into the Willy Wonka factory of weed. Learn more about your ad choices. Visit po...

If humans ever leave this solar system, they probably won't do it aimlessly. More likely they'll set a course for some distant waypoint, perhaps another solar system, to visit, study, or maybe even settle. And when they do, there's a good chance the destination they choose will have been discovered by NASA's new planet-hunting spacecraft. Called the Transiting Exoplanet Survey Satellite, the instr...
