Methane is a much more potent greenhouse gas than carbon dioxide, trapping much more heat. Point-source methane emitters are typically small—usually less than 10 meters in diameter—but they emit plumes of highly concentrated methane. So if we want to reduce the amount of methane we’re spouting into the air (which we obviously should, although we’re not), they’d be great potential targets. If only we could identify them.
To map such point emissions, scientists in California flew over the state with an airborne imaging spectrometer, using it to measure methane emissions. They focused on a long list of potential sources: oil and gas production, processing, transmission, storage, and distribution equipment; refineries; dairy-manure management sites; landfills and composting facilities; wastewater-treatment plants; gas-fired power plants; and liquified and compressed natural gas facilities.
Most facilities, especially the dairies and the oil fields, were in the San Joaquin Valley. The researchers ended up measuring emissions from 564 distinct sources at 250 different facilities. These point emitters had not really been examined before, because they often only belch out their methane intermittently or in a somewhat sporadic manner. To catch them in the act, the researchers repeated the flyovers five times between August 2016 and October 2018.
The Pixel 4 arrived on the market as one of the most leaked, most talked about smartphones of 2019. This year, Google seems like it is really trying to find something unique to offer, with new features like the Google-developed "Motion Sense" radar gesture system, face unlock, a 90Hz display, the next-gen Google Assistant, and a new astrophotography mode.
At the prices Google is asking, though, the Pixel 4 is hard to recommend. The company saddled the phone with an ultra-premium price tag, but the Pixel 4 can't compete with ultra-premium phones. The phone falls down on a lot of the basics, like battery life, storage speed, design, and more. The new additions like face unlock and Motion Sense just don't work well. It seems like Google just cut too many corners this year.
The strongest feature of the Pixel line—the camera—hasn't really gotten better, either. The camera sensor is the same as last year, and the big new software feature, astrophotography mode, is also available on older Pixel devices and the much cheaper Pixel 3a.
A fake ad blocker available outside of Google Play is bombarding Android users with ads, many of them vulgar, and to make matters worse, the cleverly hidden adware is hard to uninstall.
As documented by antimalware provider Malwarebytes, Ads Blocker, as the app is called, employs several tricks to surreptitiously and constantly bombard users with ads. The first is to simply ask for usage rights to display over other apps. Next, it makes a connection request to "set up a VPN connection that allows it to monitor network traffic." Finally, it seeks permission to add a widget to the homescreen.
In fact, approving the the VPN connection—a standard requirement for some legitimate ad blockers—allows Ads Blocker to run in the background at all times. Combined with the permission to display over other apps, the app is free to plaster ads in a variety of aggressive and annoying ways. It displays full-page ads across the screen. It delivers ads in the default browser. It includes ads in notifications. And it places ads in the homescreen widget.
Microsoft rose to dominance during the '80s and '90s thanks to the success of its Windows operating system running on Intel’s processors, a cosy relationship nicknamed “Wintel”.
Now Microsoft hopes that another another hardware–software combo will help it recapture that success—and catch rivals Amazon and Google in the race to provide cutting-edge artificial intelligence through the cloud.
Microsoft hopes to extend the popularity of its Azure cloud platform with a new kind of computer chip designed for the age of AI. Starting today, Microsoft is providing Azure customers with access to chips made by the British startup Graphcore.

We're getting a TV adaptation of Sin City, Frank Miller's series of neo-noir comics inspired by crime pulp fiction, Deadline Hollywood reports. Miller just inked a deal with Legendary Television for the project, and apparently a similar agreement is close to completion with Robert Rodriguez, who collaborated with Miller on the film adaptions of the comic series in 2005 and 2014. The agreement comes with a first season guarantee, pending a partnership with one of the major networks or streaming platforms. Given that Miller wants the series to rate a hard "R," streaming seems the most likely option.
Miller cut his teeth in the 1980s on Marvel Comics' Daredevil series and DC Comics' The Dark Knight Returns. A longtime fan of film noir, especially the films of James Cagney and Humphrey Bogart, Miller wanted to bring that same tone to Sin City, an anthology of stories set in the fictional Western town of Basin City (aka Sin City). The series art was noteworthy for its unique aesthetic, drawn almost entirely in black-and-white, with occasional bright splashes of color (red, yellow, blue, or pink) to highlight certain characters. And Miller drew on classic pulp fiction for the writing as well.
Almost every inhabitant of Sin City is corrupt, from the police department to the wealthy Roark family dynasty, with different factions carving out niches in the overall hierarchy. Miller has said he wanted it to be "a world out of balance, where virtue is defined by individuals in difficult situations, not by an overwhelming sense of goodness that was somehow governed by this godlike Comics Code." So we get stories, or "yarns," about one man's brutal rampage to avenge his lover's killer; gang warfares; and the hunt for a disfigured serial killer targeting young women. The yarns aren't necessarily connected, but they all take place in the same fictional world, and various characters recur in different stories.
Welcome to Ars Cardboard, our weekend look at tabletop games! Check out our complete board gaming coverage at cardboard.arstechnica.com.
As a longtime player of cardboard civilization games, I’m always looking for titles that break the mold. From the moment it was revealed, Jamey Stegmaier’s Tapestry looked like it might fit the bill. With its pre-painted buildings, non-historical civilizations, and the hieroglyphic script that runs the perimeter of the board, it seemed to promise a civilization game that wasn’t quite like any other.
And, well, it certainly delivers on that front. Tapestry is indeed unlike most of its civ-game peers.
The first episode of audio-obsessed podcast Reasonably Sound that made me stop and think was an early entry called "Whisper Quiet." As my introduction to Autonomous Sensory Meridian Response (ASMR), and the specific auditory cues related to its reported physical reactions, I felt like someone had taken the top off my head, rummaged around in my brain, and found something overlooked inside that was suddenly useful. And not just in an ASMR sense, though the sample clips of Bob Ross hit all the right notes for that, as did host Mike Rugnetta getting into the spirit of ASMR by whispering the end credits.
Reasonably Sound is a podcast about audio and about the historical and cultural context of particular sounds and sonic experiences. In his episode about ASMR, Rugnetta not only introduces his audiences to what ASMR is, but he also contextualizes the rise of ASMR culture on YouTube within the broader history of communication technology, starting with an AT&T advertising campaign from the 1970s promoting long-distance calls as a medium for emotional intimacy. He also digs into the jargon of ASMR culture, comparing the pleasant "triggers" found in ASMR videos to the more serious triggers of trauma responses.
Research into the causes of ASMR didn't start being published in earnest until 2015, months after the release of "Whisper Quiet," so Rugnetta mentions in a later episode that he's skeptical of the phenomenon’s existence. But, real or imagined, he acknowledges ASMR's memetic status and delights in exploring the cultural context that produced it.
Matter, despite being omnipresent here on Earth, is a bit of a mystery. Most of the matter in the Universe comes in the form of dark matter, which doesn't seem to have significant interactions with light or other matter. Meanwhile, the more familiar form of matter shouldn't be here at all. It should have been created in equal amounts to antimatter, allowing the two to annihilate each other following the Big Bang.
Physicists have found a few ways of breaking the matter/antimatter symmetry, but they aren't sufficient to account for matter's vast predominance. So, there are lots of ideas floating around to handle it, and some of them are even testable. One of the more intriguing categories of solution links the two big problems with matter: tying the prevalence of matter to the existence of a specific dark matter particle.
Now, scientists have made some antimatter in a lab and used that to test one of these ideas. The test came up blank, putting limits on the possible link between dark matter and antimatter's absence.
Ride pick-up app's algorithm offers drivers freedom while trapping them at the same time, experts say.
Drew Stewart got the call at around 2am: They broke the universe again, you should check it out.
So Stewart did something he's done countless times before; he has no idea how many. He turned on Star Wars. But this time was different—literally. The galaxy had changed, like a glitch in the Matrix (if you'll allow a mixed cinematic metaphor). And it wasn't the first time.
As the person behind a Twitter account called Star Wars Visual Comparison, Stewart is a kind of unofficial keeper of apocrypha, of the sometimes subtle, sometimes extraordinary changes wrought by their makers upon three Star Wars movies: A New Hope, The Empire Strikes Back, and The Return of the Jedi. These alterations to the canon are the stuff of many nerd debates, and Stewart has followed them closely. That's why, at 2:50am on the day Disney+ launched with the whole Star Wars catalog in 4K resolution (pretty!), he found himself watching A New Hope yet again. What he found was yet another wrinkle: an all-new, all-different shoot-out between Han Solo and the lizardish bounty hunter Greedo.
Google, and its parent company Alphabet, has its metaphorical fingers in a hundred different lucrative pies. To untold millions of users, though, "to Google" something has become a synonym for "search," the company's original business—a business that is now under investigation as more details about its inner workings come to light.
A coalition of attorneys general investigating Google's practices is expanding its probe to include the company's search business, CNBC reports while citing people familiar with the matter.
Attorneys general for almost every state teamed up in September to launch a joint antitrust probe into Google. The investigation is being led by Texas Attorney General Ken Paxton, who said last month that the probe would first focus on the company's advertising business, which continues to dominate the online advertising sector.
The Supreme Court has agreed to review one of the decade's most significant software copyright decisions: last year's ruling by an appeals court that Google infringed Oracle's copyrights when Google created an independent implementation of the Java programming language.
The 2018 ruling by the Federal Circuit appeals court "will upend the longstanding expectation of software developers that they are free to use existing software interfaces to build new computer programs," Google wrote in its January petition to the Supreme Court.
The stakes are high both for Google and for the larger software industry. Until recently, it was widely assumed that copyright law didn't control the use of application programming interfaces (APIs)—standard function calls that allow third parties to build software compatible with an established platform like Java.
The same team who tied the first "quantum knots" in a superfluid several years ago have now discovered that the knots decay, or "untie" themselves, fairly soon after forming, before turning into a vortex. The researchers also produced the first "movie" of the decay process in action, and they described their work in a recent paper in Physical Review Letters.
A mathematician likely would define a true knot as a kind of pretzel shape, or a knotted circle. A quantum knot is a little bit different. It's composed of particle-like rings or loops that connect to each other exactly once. A quantum knot is topologically stable, akin to a soliton—that is, it's a quantum object that acts like a traveling wave that keeps rolling forward at a constant speed without losing its shape.
Physicists had long thought it should be possible for such knotted structures to form in quantum fields, but it proved challenging to produce them in the laboratory. So there was considerable excitement early in 2016 when researchers at Aalto University in Finland and Amherst College in the US announced they had accomplished the feat in Nature Physics. The knots created by Aalto's Mikko Möttönen and Amherst's David Hall resembled smoke rings.
Apple has removed all 181 vaping-related apps from the iOS App Store, Axios reported on Friday morning. The move follows rising concern about the possible health impacts of vaping.
Some of the banned apps provided news and information about vaping. Some were vaping-themed games. There were also apps that allowed users to adjust the temperature and other settings on their vaping devices.
To avoid breaking functionality for existing customers, Apple is allowing them to continue using vaping apps already on their devices—and to transfer them to new devices. But new users won't be able to download these apps, and new vaping apps can't be published on Apple's store.
Huawei's futuristic foldable smartphone, the Huawei Mate X, is finally a real product. The phone went on sale in China today for the heart-stopping price of $2,421 (16,999 yuan).
Just like that other foldable smartphone on the market, the Galaxy Fold, the Mate X had a very bumpy road on its way to market full of delays and setbacks. The phone was originally scheduled for release in "the middle of the year," but in the midst of the US' Huawei export ban and the Galaxy Fold's initial delay, Huawei opted to delay the Mate X. The new launch target was September, but when September rolled around, the phone was delayed again to today's November 15 launch date.
Trade War! USA v. China
Ten months after his arrest by a swarm of FBI agents, former Trump adviser and self-proclaimed "dirty trickster" Roger Stone was found guilty of all seven felony counts against him, including obstruction of Congress, five counts of false testimony to Congress, and witness tampering. The conviction is the eighth guilty sentence or plea resulting from grand jury indictments spawned by the investigations into Russian election interference by Special Counsel Robert Mueller.
At the center of the case was Stone's quest in the months leading up to the 2016 presidential election to obtain the emails from WikiLeaks stolen by Russian Main Intelligence Directorate (GRU) operatives from the Democratic National Committee and people within Hillary Clinton's presidential campaign organization. Stone frequently bragged about his connections with WikiLeaks' Julian Assange, and Stone communicated with the Trump campaign about WikiLeaks' plans to release those emails “every chance he got,” said lead federal prosecutor Jonathan Kravis.
Stone was found to have concealed the nature of his communications with WikiLeaks and to have lied to Congress about who acted on his behalf in those contacts. And he attempted to dissuade one of those intermediaries, radio personality Randy Credico, from contradicting his false testimony to Congress, making Godfather II references in his messages to Credico—threatening to take away his therapy dog and to order his lawyers to "rip you to shreds." At one point, Stone allegedly even texted Credico, "Prepare to die [expletive]."
Move over, Dark Lord of Mordor. There’s a new blazing peeper in town.
Doctors in Texas came face to face with a dark, spine-tingling eye that looked rimmed by flames—or, as they calmly described it in a recent report in the New England Journal of Medicine: an eye with “circumferential spoke-like iris transillumination defects.”
They met this penetrating gaze during the routine eye exam of a 44-year-old man. The man had come into their Texas ophthalmology clinic simply to establish care as a new patient. He had recently moved into the area.
