Donald Trump's choice to lead the Department of Transportation, Elaine Chao, has worked hard to avoid placing regulatory barriers in the way of self-driving cars. But Chao's boss is a driverless car skeptic, Axios reports.
One Axios source had a conversation with Trump in 2017 where he mentioned owning a Tesla with Autopilot technology. According to the source, Trump "was like, 'Yeah that's cool but I would never get in a self-driving car... I don't trust some computer to drive me around.'"
On another occasion, Trump reportedly said, "Can you imagine, you're sitting in the back seat and all of a sudden this car is zig-zagging around the corner and you can't stop the f---ing thing?"
In a large Apple-sponsored study assessing whether the pulse sensor on older versions of the Apple Watch (Series 1, 2, and 3) can pick up heart rhythm irregularities, researchers found that only 34 percent of participants who received an alert of an irregular pulse on their watch went on to have a confirmed case of atrial fibrillation, a common type of irregular heart rhythm.
The study was led by researchers at Stanford, who presented the results Saturday in New Orleans at the annual meeting of the American College of Cardiology. The results have not been published in a scientific journal and have not been peer-reviewed.
The study, dubbed the Apple Heart Study, began in November 2017, before the release of the Apple Watch Series 4, which includes an electrocardiograph (ECG) feature for monitoring heart activity. Though the study didn’t keep pace with that of wearable device development, it was rather speedy relative to clinical trials. In fact, some cardiologists were impressed simply by the short period of time in which the study was able to recruit such a large number of participants—nearly 420,000—plus follow up with them using telemedicine and get results.
SAN FRANCISCO—In 2017, game designer and writer Chet Faliszek left Valve Software. The departure was notable in part because Faliszek was perhaps second only to company co-founder Gabe Newell in terms of public exposure, but also because Faliszek's work represented a seemingly long-gone era at the game studio: one of irreverent, story-driven games that emphasized co-op (both Left 4 Dead games and Portal 2, among other titles).
Shortly after that departure, Faliszek emerged with news: he would start making games at Bossa Studios, home of goofy titles like Surgeon Simulator and I Am Bread. It seemed like a good fit. Turns out, it wasn't.
After roughly a year working together, Faliszek and the Bossa Studios team "reconvened and decided it wasn't working out," he told Ars Technica. On one hand, Faliszek described the end of that relationship as "the hardest breakup, because I couldn't get mad at them." On the other, when pressed, Faliszek described the game he'd worked on as "a kind of game they're not known for making, and kind of maybe not suited for making."

We're one week out from Apple's services-focused event in Cupertino, and the company just announced a pair of devices we've been expecting for quite some time. Apple debuted a new, $499 10.5-inch iPad Air and a new, $399 7.9-inch iPad mini today. Both have familiar designs but also have the company's new A12 Bionic chip.
The new iPad Air looks like previous models, with thicker bezels on the top and bottom of the advanced Retina display (now with True Tone technology) to house the camera array and the physical Home button. While both new iPads have updated cameras that can better handle low-light situations and immersive AR experiences, they appear to omit FaceID entirely.
Inside the iPad Air is the new A12 Bionic chip with Apple's neural engine, and the company claims it will make the new Air 70 percent faster than previous versions, with twice the graphics power. The updated display now supports the Apple Pencil as well, giving more users the opportunity to draw, sketch, and take notes on an iPad.
For months in south Texas, SpaceX employees have been assembling a test version of the upper stage for its next-generation launch system. This prototype "Starship" is far from space-worthy, but it will allow the company to test the vehicle's ability to "hop" from the spaceport and then land propulsively back on the ground.
On Friday, the company sent a notice to nearby residents saying it planned to conduct testing of the vehicle as soon as the week of March 18, and that it would be closing the main roadway of Highway 4 to non-residents during the tests. This "safety zone perimeter" is part of an agreement with the local county, and has been set up out of an abundance of caution.
On Sunday, company founder Elon Musk confirmed on Twitter that SpaceX was indeed close to beginning tests. Musk said that integration work remained to be done on test vehicle and its Raptor rocket engine, and that the first hops would lift off, but only "barely." Eventually the "Starhopper" test vehicle will have three engines, but for now it appears as though the company will start with just one.

A mariner's astrolabe recovered from the wreck of one of Portuguese explorer Vasco da Gama's ships is now officially the oldest known such artifact, according to a new paper in the International Journal of Nautical Archaeology. The device is even going into the Guinness Book of World Records, along with the ship's bell, now that the age of both artifacts has been independently verified.
A key distinction here is that this is the oldest known mariner's astrolabe. Astrolabes are actually very ancient instruments—possibly dating as far back as the second century BCE—for determining the time and position of the stars in the sky by measuring a celestial body's altitude above the horizon. They were mostly used for astronomical studies, although they also proved useful for navigation on land. Navigating at sea on a pitching deck was a bit more problematic, unless the waters were calm.
The development of a mariner's astrolabe—a simple ring marked in degrees for measuring celestial altitudes—helped solve that problem. It was eventually replaced by the invention of the sextant in the 18th century, which was much more precise for seafaring navigation. Mariner's astrolabes are among the most prized artifacts recovered from shipwrecks; only 108 are currently catalogued worldwide.
There's a scene somewhere in the middle of a new flat Earth documentary that acts as a metaphor for so much that surrounds it. Two of the central figures of Behind the Curve are visiting a spaceflight museum that pays tribute to NASA, an organization that they believe is foisting a tremendous lie on an indoctrinated and incurious public. One of them, Mark Sargent, sits in a re-entry simulator that suggests he should press "Start" to begin. He dutifully bangs away at the highlighted word "Start" on screen, but nothing happens.
He wanders away muttering even more about how NASA's a giant fraud. Meanwhile, the camera shifts back to the display and zeroes in on the giant green "Start" button next to the seat Sargent was in.Into the fringes
It's hard not to think back to two earlier scenes in the movie. In the first, Sargent talks about how he started having suspicions about the globe when he spent weeks watching a flight tracker for flights crossing the southern oceans but couldn't find any. This seemed to fit with his favored model of the Earth's disk, one with the North Pole at the center and the continents spread out like spokes from there. This would place the southern continents much farther apart and make air travel prohibitive—just as the lack of flights suggested.
Here's a poorly kept secret: the internal chatter at a given research and scientific institution is typically more interesting than what emerges on the public record. Published papers and newspaper interviews don't come with the banter, pop-culture references, or sheer wit that pumps through most nerds' veins.
I thought back to all that nerd humor when I reflected on Human Nature, a documentary about gene editing and CRISPR that had its world premiere at South by Southwest 2019. There's a lot of ground to cover on such a topic, and the film, co-produced by Dan Rather, does quite well by identifying existing research and studies, then grounding them with context and equal parts optimism and pessimism. But Human Nature is also the rare science film that isn't afraid to let its smart talking heads be funny, dorky, or just plain sharp.
Meaning: if you already know everything about CRISPR (and if you read Ars Technica, you very well might), Human Nature still has something for you.
AUSTIN, Texas—While sitting in the auditorium waiting to hear Massachusetts Senator Elizabeth Warren talk further about her views on Silicon Valley, an older gentleman leaned over to ask about something that had absolutely nothing to do with politics. "I don't get it," he began. "It's a music festival, but a film festival, too? And you're here for the technology stuff, right? Where do all these politicians fit? How do you describe this conference to someone in 30 seconds?"Ars at SXSW 2019
The answer, of course, is obvious to Ars after our fourth straight year of coverage: you can't. While the three core tenets of South by Southwest remain film, music, and tech, this conference has become the ultimate convergence event—not just of topics, but of people. Where else can you, in a single day, see a cookie vending machine from Milk Bar baking guru Christina Tosi, a massive HBO installation to promote Game of Thrones, experts from Unicode talking about emoji evolution, and then Senator Warren on -isms from capital- to rac- all in the same place? None of that stuff perfectly fits into SXSW's overarching programming tracks, but perhaps that itself is the message. These days, the boundaries between art, business, and innovation blur together more than ever. Put a bunch of movers and shakers in those areas together for a week, and interesting stuff is bound to happen.
Unfortunately, explaining that (even succinctly) takes more than 30 seconds, so we failed this impromptu summarization quiz. But our time in Austin certainly felt like a success overall. Above is just a small sampling of the sights that spanned almost every topic you can find on the pages of Ars Technica. We may have missed Bill Nye crashing New York Congresswoman Alexandria Ocasio-Cortez's Q&A to talk about the environment, but we damn well made sure to snag one of those cookies.
Generally speaking, it’s easy enough to make sense of the last few million years of climate patterns—the world looked much as it does today, so changes in greenhouse gas concentrations or ocean circulation can be related to what we see now. But as you go back farther in time, you can find very different climates and a rearranged map of continents, and those require more creative thinking.
For example, the ice age periods in the recent past are not unique. But most of the last 500 million years have been much warmer—what has caused the climate to slowly drift toward warmer or cooler temperatures over millions of years?Looping
In the grand sweep of Earth history, its climate has remained within a habitable temperature range—thanks in part to the moderating influence of feedback loops within the system. The weathering of silicate minerals in bedrock pulls CO2 out of the atmosphere, for example. In a warming climate, weathering can speed up, removing more greenhouse gas and stabilizing temperatures. Cool the planet and weathering slows, giving greenhouse gases more chance to accumulate.
In January 2018 a group of hackers, now thought to be working for the North Korean state-sponsored group Lazarus, attempted to steal $110 million from the Mexican commercial bank Bancomext. That effort failed. But just a few months later, a smaller yet still elaborate series of attacks allowed hackers to siphon off 300 to 400 million pesos, or roughly $15 to $20 million from Mexican banks. Here's how they did it.
At the RSA security conference in San Francisco last Friday, penetration tester and security advisor Josu Loza, who was an incident responder in the wake of the April attacks, presented findings on how hackers executed the heists both digitally and on the ground around Mexico. The hackers' affiliation remains publicly unknown. Loza emphasizes that while the attacks likely required extensive expertise and planning over months, or even years, they were enabled by sloppy and insecure network architecture within the Mexican financial system, and security oversights in SPEI, Mexico's domestic money transfer platform run by central bank Banco de México, also known as Banxico.Easy pickings
Thanks to security holes in the targeted bank systems, attackers could have accessed internal servers from the public Internet, or launched phishing attacks to compromise executives—or even regular employees—to gain a foothold. Many networks didn't have strong access controls, so hackers could get a lot of mileage out of compromised employee credentials. The networks also weren't well segmented, meaning intruders could use that initial access to penetrate deep into banks's connections to SPEI, and eventually SPEI's transaction servers, or even its underlying code base.
