An anonymous reader quotes a report from Phys.Org: A team of researchers led by Osaka University and National Taiwan University created a system of nanoscale silicon resonators that can act as logic gates for light pulses. ... [The scientists] have increased the nonlinearity of silicon 100,000 times by creating a nano-optical resonator, so that all-optical switches can be operated using a continuous low-power laser. They accomplished this by fabricating tiny resonators from blocks of silicon less than 200 nm in size. Laser light with a wavelength of 592 nm can become trapped inside and rapidly heat the blocks, based on the principle of Mie resonance. "A Mie resonance occurs when the size of a nanoparticle matches a multiple of the light wavelength," author Yusuke Nagasaki says.

With a nanoblock in a thermo-optically induced hot state, a second laser pulse at 543 nm can pass with almost no scattering, which is not the case when first laser is off. The block can cool with relaxation times measured in nanoseconds. This large and fast nonlinearity leads to potential applications for GHz all-optical control at the nanoscale. "Silicon is expected to remain the material of choice for optical integrated circuits and optical devices," senior author Junichi Takahara says. The current work allows for optical switches that take up much less space than previous attempts. This advance opens the way for direct on-chip integration as well as super-resolution imaging. The study has been published in the journal Nature Communications.

In an effort to cut road deaths, the Dutch government will be using a new digital system to automatically reduce electric bicycles' power in residential or built-up areas of Amsterdam. The Guardian reports: The digital technology, which has been successfully trialled on a 4km stretch of bike lanes at Schiphol airport, was funded by the Dutch ministry of infrastructure and water management. The not-for-profit Townmaking Institute behind the concept is working with e-bike manufacturers and government authorities with the expectation that the speed-cutting technology and new regulations could be rolled out by 2022.

Sixty-five people died last year while riding e-bikes, which have an integrated electric motor to propel the wheels, up from 57 in 2018. The vast majority were men over the age of 65. The standard e-bike reaches speeds of 12mph (20km/h), but faster models, such as speed pedelecs, can reach 28mph. Discussions over the use of the technology are most advanced with the municipality of Amsterdam, but the provinces of Gelderland and North Holland are also said to have shown an interest.

The technology trialled at Schiphol offers policymakers a range of options. "Say the weather is really bad, there is a headwind of 40km and cyclists are at a standstill, then cutting off the power would be counterintuitive," said [Indranil Bhattacharya, a technology strategist at the Townmaking Institute]. "We built it so you can detect the direction the bike is going, and a policymaker can say: 'We change the regulation. We won't cut your power off because the weather is bad.' The intelligent infrastructure would then tell the bicycle not to cut off the power.â The infrastructure could also inform an e-bike of upcoming obstacles or junctions, by alerting cyclists with a gentle vibration of the handlebars.

Earlier this week, the FCC fined T-Mobile $200 million for its abuse of Sprint's Lifeline program for low-income consumers -- the largest fine to be paid in commission history. Now, the Better Business Bureau's National Advertising (NAD) is telling T-Mobile to tone down its misleading 5G claims about having the "best 5G network." Gizmodo reports: The NAD's investigation of T-Mobile's 5G claims, reported by Android Police, concluded yesterday. While the BBB division found that some of the carrier's post-Sprint merger claims had merit, like T-Mobile's assertion that it will build the nation's largest 5G network due to the merger, it asked the carrier to change the language of some of its other misleading claims. Specifically, the NAD took issue with T-Mobile telling consumers they will get the best 5G network. NAD said that consumers could "reasonably interpret" these claims to mean T-Mobile currently provides the best 5G network and that T-Mobile customers will "imminently" have 5G coverage when that's not currently the case.

"NAD determined that the challenged advertisements did not reasonably convey a present-tense message that the aspirational future benefits from T-Mobile are presently available to consumers," the group said. "NAD recommended that the challenged advertising be modified to avoid conveying such messages."

According to XDA Developers, Google is testing locking the Color Pop feature in the Google Photos app behind a paywall, requiring users to sign up for a Google One subscription to access this feature, and presumably other photo-editing features in the future. From the report: Shortly after we published our teardown of Google Photos 5.18 confirming that a Google One paywall for photo editing features is in the works, a reader in the comments section informed us that the Color Pop feature is locked behind a Google One membership for him. We've attached the two screenshots shared by the user, and we've also added two screenshots showing off the Color Pop feature in action (this was from a Google account that doesn't have a Google One subscription).

The feature essentially keeps the subject in color while turning the background black and white (or vice versa), allowing the subject to "pop." It's a fun feature, and seemingly one Google thinks is advanced enough to convince people to pay for. It's unclear what other premium editing features will be put behind a paywall. However, we recently uncovered strings of code in version 5.18 that suggest Google will introduce preprocessing suggestions and a Skypalette feature, which will include new filters to help users edit the sky. UPDATE: Google has clarified that the Color Pop being reported above is not the same Color Pop feature that's available in Google Photos today. "Right now in Google Photos, Color Pop is only available on photos taken in portrait mode, meaning there is depth information available, which is especially helpful in making the background of an image pop," reports 9to5Google. "The version of Color Pop that will be locked behind Google One will work on photos without depth information. Likely this version attempts to use machine learning to automatically differentiate the foreground from the background."

"More importantly, this means that Google Photos will not be putting an existing feature behind a Google One paywall. Instead, it seems Google intends to create new features to incentivize Google One subscribers."

An anonymous reader quotes a report from VICE: On Thursday night, Facebook announced it had activated "break glass" measures to try to quell the spread of disinformation, which has been supercharged by the lies being spread by President Donald Trump and his allies. The unprecedented move may have been triggered by Facebook's decision hours earlier to shut down a viral group called "Stop the Steal" that had racked up 360,000 in the space of 24 hours. The group was spreading disinformation, advocating for gun violence, and organizing real-world protests. But the impact of Facebook's moves has been negligible.

A VICE News investigation, using the Facebook-owned analytics tool CrowdTangle, found at least three active groups on Facebook using variations of the Stop the Steal name, all of which have tens of thousands of followers and all of which are sharing the same disinformation as the original group. The biggest group identified is called "StoptheSteal" which has almost 70,000 members. The next biggest is called "Stop the Steal 2.0" with 40,000 followers. Finally, a group with an identical name -- "Stop the Steal" -- has 25,800 members. By allowing the original group to grow so quickly, and to such a scale before removing it, Facebook could have inadvertently made the situation even worse, Ciaran O'Connor, an analyst at the Institute for Strategic Dialogue, told VICE News. "The challenge in managing copycat groups is that there is additional potential for voter fraud disinformation and threats of violence among communities who may be motivated for further action given the removal of the original group, particularly around possible mobilization at election centers." "We are continuing to review additional content and activity and will take action accordingly," Facebook spokesman Andy Stone told VICE News.

The federal government has cleared the way for collection agencies to send unlimited texts, emails and even instant messages to debtors on social media platforms. CBS News reports: The Consumer Financial Protection Bureau issued a final rule late last week outlining how collectors can use new communication methods. The federal agency, which is charged with protecting Americans from financial abuse, did not limit the number of messages collectors could send, but it did require that each message come with instructions on how to opt out. The bureau also limited the number of times collectors may call someone to seven calls per week for each debt.

Consumer advocates criticized the rule for not requiring alleged debtors to consent before being contacted by email or text, and for setting a limit on phone contact that could result in a flood of calls for people who owe money to several creditors. Jay Gonsalves, president of Action Collection Agencies in Boston, called the rule a "win-win."

"We're hearing more and more from consumers that they don't want to talk to us on the phone. Nobody does anymore. Everyone communicates with text," said Gonsalves, formerly president of the Association of Credit and Collection Professionals, the collection industry's trade group. While consumers may not appreciate hearing about what they owe, Gonsalves added that keeping a debtor in the dark could hurt them in the long term. The rule will formally take effect one year after it's published in the Federal Register, or near the end of 2021.

An anonymous reader quotes a report from Ars Technica: Time is starting to run out for vehicles powered purely by international combustion engines, and the auto industry knows it. This week Bentley, that bastion of British luxury, became the latest OEM to set a date for that happening -- the year 2030. As the company moves into its second century, it has revealed a new plan called "Beyond 100" that it says will "reinvent every aspect of its business to become an end-to-end carbon neutral organization.

Bentley already introduced a plug-in hybrid EV version of the Bentayga SUV and next year it plans to add another pair of PHEVs to its roster -- presumably the Continental GT coupe and Flying Spur sedan. In 2025, the company plans to introduce a battery electric vehicle; Bentley CEO Adrian Hallmark told Autoweek that "you've got to pick a point in time where battery power density, especially for bigger cars, is the liberator for us. We've always said that the mid-2020s is the time when you can expect to see 120-plus kilowatt-hour batteries coming through the supply chain." 2025 will also be the last year you'll be able to buy a Bentley that doesn't plug in, because in 2026 the brand is dropping everything other than PHEVs and BEVs. In 2030, those PHEVs will be gone, too, leaving just BEVs to wear the winged B badge with pride. Along the way, Bentley is also pledging to reduce its factory's environmental impact and go plastic neutral.

As work continues on Novi, Facebook's digital wallet the company hopes will one day be used to access currencies in the blockchain-based payment system Libra, semblances of a framework have emerged from new research published in AFT '20: Proceedings of the 2nd ACM Conference on Advances in Financial Technologies. From a report: A paper coauthored by scientists at Facebook's Novi division proposes a transaction settlement system called FastPay, which they claim can be used to settle cryptocurrency payments or as infrastructure to support retail payments in fiat currencies. In experiments, the team managed to achieve "intra-continental" confirmation of less than 100 milliseconds and over 80,000 transactions per second with as many as 20 different payment authorities. [...]

FastPay aims to solve this by enabling authorities to jointly maintain account balances and settle prefunded retail payments between accounts. The researchers claim it supports "subsecond" latency confirmation appropriate for physical point-of-sale payments while providing capacity comparable with peak retail card network volumes and real-time gross settlement. [...] In experiments, they claim FastPay supported up to 160,000 transactions per second under a total load of 1.5 million transactions across the 48 cores -- about seven times the peak transaction rate of the Visa payments network -- while running on commodity computers that cost less than $4,000 a month to run.

hackingbear writes: China successfully launched the world's first 6G communication satellite by a Long March-6 carrier rocket that blasted off from the Taiyuan Satellite Launch Center, China Central Television (CCTV) reported. The 6G experimental satellite, named after the University of Electronic Science and Technology of China (UESTC), was jointly developed by Chengdu Guoxing Aerospace Technology, UESTC, and Beijing MinoSpace Technology. It will be used to verify the performance of 6G technology in space as the 6G frequency band will expand from the 5G millimeter wave frequency to the terahertz frequency. The technology is expected to be over 100 times faster than 5G, enabling lossless transmission in space to achieve long-distance communications with a smaller power output.

Facebook plans to put the name of the winner of the US presidential election at the top of Facebook and Instagram once it's been projected by a majority of media outlets, the company says. From a report: The company also will label presidential candidates' posts with a link to its voting information center, according to Facebook spokesperson Tom Reynolds. The company plans to "show the candidate's name in notifications at the top of Facebook and Instagram that say 'A Presidential Winner Has Been Projected -- is the projected winner of the 2020 US Presidential Election,'" Reynolds explained in an email to The Verge. Facebook will rely on "a majority opinion from Reuters as well as independent decision desks at major media outlets, including ABC News, CBS News, Fox News, NBC News, CNN, and The Associated Press to determine when a presidential winner is projected," Reynolds says.

The first detection of a fast radio burst inside the Milky Way leads scientists back to a magnetar, partially solving a long-standing mystery. CNET reports: Sifting through a trove of radio telescope data in 2007, Duncan Lorimer, an astrophysicist at West Virginia University, spotted something unusual. Data obtained six years earlier showed a brief, energetic burst, lasting no more than 5 milliseconds. Others had seen the blip and looked past it, but Lorimer and his team calculated that it was an entirely new phenomenon: a signal emanating from somewhere far outside the Milky Way. The team had no idea what had caused it but they published their results in Science. The mysterious signal became known as a "fast radio burst," or FRB. In the 13 years since Lorimer's discovery, dozens of FRBs have been discovered outside of the Milky Way -- some repeating and others ephemeral, single chirps. Astrophysicists have been able to pinpoint their home galaxies, but they've struggled to identify the cosmic culprit, putting forth all sorts of theories, from exotic physics to alien civilizations.

On Wednesday, a trio of studies in the journal Nature describes the source of the first FRB discovered within the Milky Way, revealing the mechanism behind at least some of the highly energetic radio blasts. The newly described burst, dubbed FRB 200428, was discovered and located after it pinged radio antennas in the US and Canada on April 28, 2020. A hurried hunt followed, with teams of researchers around the globe focused on studying the FRB across the electromagnetic spectrum. It was quickly determined that FRB 200428 is the most energetic radio pulse ever detected in our home galaxy.

In the suite of new papers, astrophysicists outline their detective work and breakthrough observations from a handful of ground- and space-based telescopes. Linking together concordant observations, researchers pin FRB 200428 on one of the most unusual wonders of the cosmos: a magnetar, the hypermagnetic remains of a dead supergiant star. It's the first time astrophysicists have been able to finger a culprit in the intergalactic whodunit -- but this is just the beginning. "There really is a lot more to be learned going forward," says Amanda Weltman, an astrophysicist at the University of Cape Town and author of a Nature news article accompanying the discovery. "This is just the first exciting step."

A Tesla-branded tequila, which is being described as a "small-batch premium 100% de agave tequila anejo made from sustainably sourced highland and lowland agaves," is now being sold on the automaker's website for $250. It comes in a handblown glass bottle shaped in the electric charge symbol. TechCrunch reports: The tequila first popped up in April 2018 when Musk tweeted a photo of himself passed out against a Tesla Model 3 "surrounded by 'Teslaquilla' bottles, the tracks of dried tears still visible on his cheeks." In the photo, Musk is holding a cardboard sign that reads "bankwupt." Later that year, Tesla filed an application with the U.S. Patent and Trademark Office to trademark "Teslaquila."

A series of tweets by one Miami University student that were critical of a proctoring software company have been hidden by Twitter after the company filed a copyright takedown notice. TechCrunch reports: Erik Johnson, a student who works as a security researcher on the side, posted a lengthy tweet thread in early September about Proctorio, an Arizona-based software company that several U.S. schools -- including his own -- use to monitor students who are taking their exams remotely. But six weeks later, Johnson received an email from Twitter saying three of those tweets had been removed from his account in response to a request by Proctorio filed under the Digital Millennium Copyright Act.

Proctorio, based in Scottsdale, Arizona, says its proctoring software is privacy friendly. Students are required to install its Chrome extension before taking a test, which the company says students can remove once they're done. Unlike desktop software, most Chrome extensions can be easily downloaded and their source code viewed and examined. Johnson did this and tweeted his findings. Three of those tweets described under what circumstances Proctorio would "terminate" a student's exam if it detected signs of potential cheating -- such as if a student "switched networks" or if "abnormal clicking" and "eye movements" were detected. The tweets also included a link to snippets of code found in Proctorio's Chrome extension, which Johnson posted to code-sharing site Pastebin. Those three tweets are no longer accessible on Twitter after Proctorio filed its takedown notices. The code shared on Pastebin is also no longer accessible, nor is a copy of the page available from the Internet Archive's Wayback Machine, which said the web address had been "excluded." Proctorio emailed TechCrunch a statement through its crisis communications firm Edelman, claiming Johnson "violated Proctorio's exclusive rights by copying and posting extracts from Proctorio's software code on his Twitter account," and in response, Proctorio filed the DMCA takedown request "to ask that the content be removed and Twitter removed it."

"Mr. Johnson's claim that he has the right to reproduce the code because he was able to download it is simply not true. Regardless of his ability to download the files, they remain protected under the Copyright Act. Also, had Mr. Johnson looked at the files he downloaded, he would have seen the multiple copyright notices in the header of each file that state expressly that the code is owned by Proctorio and that 'unauthorized reproduction, display, modification, or distribution of this software, or any portion of it, may result in severe civil and criminal penalties, and will be prosecuted to the full extent permitted by law.' His reproduction of that code violated Proctorio's rights, which is why Proctorio asked Twitter to remove it," said Edelman's senior vice president Andy Lutzky, on behalf of Proctorio.

Volvo Trucks, Sweden's AB Volvo's main truck brand, will sell a complete range of electric, heavy-duty trucks in Europe starting in 2021, the company said in a statement on Thursday. Reuters reports: Volvo said it was currently running tests of the electric heavy-duty Volvo FH, Volvo FM and Volvo FMX trucks, to be used for regional transport and urban construction operations in Europe. The trucks will have a gross combination weight of up to 44 tons, and, depending on the battery configuration, the range could be up to 300 kilometers, Volvo said. Sales will begin in 2021 and volume production will start in 2022.

Google officially introduced its Android mobile operating system on November 5th, 2007, which just so happens to line up with today, so happy 13th birthday, Android. Ryne Hager from Android Police reports: On November 5th, 2007, the "Open Handset Alliance" was revealed after long speculation that Google would enter the smartphone market, following the purchase of a little startup named "Android." Rumors had swirled surrounding a potential "Gphone," but Google quashed them as it announced that Android would be an open platform for anyone. Companies including Motorola, Qualcomm, HTC, and T-Mobile were all on board to help deliver the hardware and partnerships the nascent platform would require.

Google promised that Android would change the status quo, and it definitely delivered, with it now claiming over 72% of the worldwide smartphone market share, according to some recent estimates (if not more). It's the primary vehicle that has allowed billions of people to get online in emerging markets, and it's the reason our site even exists.

An anonymous reader quotes a report from TorrentFreak: Every week, Netflix sends out thousands of takedown requests, most of which target pirated copies of its movies and TV-shows. Yesterday, however, we spotted a series of copyright infringement notices with a different and rather uncomfortable theme. The streaming giant asked Twitter to remove dozens of tweets that included footage from the French coming-of-age film Cuties. This film hasn't been without controversy and the same can be said about the takedown requests too.

To provide some context, Netflix acquired the global distribution rights for Cuties and started promoting it this summer. This created quite some backlash as many people felt that the young actors had been sexualized after being filmed in all kinds of suggestive poses. We won't go into the various viewpoints on this topic or the lawsuit Netflix faces in Texas over 'lewd visual material.' Opinions from both sides are readily available all over the web, including social media. Netflix didn't cancel Cuties, however, but this week it actively started to pull Cuties clips from Twitter. Not just a handful, but several dozens. Legally the company is allowed to do this of course, as they own the rights. However, it is at least a bit peculiar that the company appears to have targeted only negative tweets. The good news is that the texts of the tweets remain online. We don't know if that is Twitter's decision or if Netflix had a say in it. The takedown requests, which are posted on Lumen, target the full tweet URLs. The flagged tweets, according to TorrentFreak, all condemn Netflix. "The language is quite harsh at times, including terms such as child exploitation, pedophilia, as well as repeated calls to cancel Netflix," it adds.

The company hasn't said why it's suddenly going after Cuties clips on Twitter. "The easy conclusion would be that Netflix is trying to shove these under the carpet," reports TorrentFreak. "However, there are still thousands of similar comments online, so that wouldn't be very effective."

Amazon.com is launching air cargo operations in Europe, the online retailer's first such expansion outside of the U.S. as it looks to bring more freight operations in-house. From a report: Amazon Air will run a 20,000-square-meter regional air hub at Leipzig/Halle airport in Germany, with two branded Boeing Co. 737-800 freighters flown by ASL Airlines, the company said in a statement. The facility will employ 200 people. Operating its own aircraft will let the world's largest e-commerce company offer "more flexible delivery options," Amazon said. The company unveiled the air cargo service in 2016, reducing its reliance on United Parcel Service and FedEx.

GitHub has denied rumors today of getting hacked after a mysterious entity shared what they claimed to be the source code of the GitHub.com and GitHub Enterprise portals. From a report: The "supposed" source code was leaked via a commit to GitHub's DMCA section. The commit was also faked to look like it originated from GitHub CEO Nat Friedman. But in a message posted on YCombinator's Hacker News portal, Friedman denied that it was him and that GitHub got hacked in any way. Friedman said the "leaked source code" didn't cover all of GitHub's code but only the GitHub Enterprise Server product. This is a version of GitHub Enterprise that companies can run on their own on-premise servers in case they need to store source code locally for security reasons but still want to benefit from GitHub Enterprise features. Friedman said this source code had already leaked months before due to its own error when GitHub engineers accidentally "shipped an un-stripped/obfuscated tarball of our GitHub Enterprise Server source code to some customers."

Facebook recently announced that WhatsApp passed the whopping milestone of 100 billion messages sent per day, but not everyone wants those chats to stick around forever. Now, Facebook's wildly popular messaging app with 2 billion users is adding a feature to give people more control on how their words and pictures live within the app. From today, messages -- including photos and videos -- can now be marked to disappear after 7 days. From a report: Disappearing messages are being rolled out globally across Android and iOS starting today, WhatsApp said. While it's starting with a 7 day lifespan, it is already looking at playing around with the time limits. "We will keep an eye on feedback about how people are using it and liking it and see if it needs adjusting in the future," a spokesperson said. "For now we are starting with seven days, because it feels like a nice balance between the utility you need for global text based conversations and the feeling of things not sticking around forever." And just to be clear, the 7-day limit will exist regardless of whether the message gets read or not. (The disappearing message clock starts counting when the message is sent, as it does on other apps like Telegram.)

An anonymous reader quotes a report from TorrentFreak: Documents obtained by TorrentFreak dated September reveal the MPA, acting through legal representatives, attempting to pressure individuals who they believe are important at [anime site Nyaa] and could have the ability to shut the site down. Information suggests that several people in North America, Europe, and Australia have all received similar correspondence. The letters allege massive copyright infringement via the Nyaa site and include a sample of copyrighted works, to which the MPA's members hold the rights, that were allegedly infringed via the platform.

The MPA clearly states that none of its cited members (Disney, Paramount, Universal, Columbia, Warner Bros, and Netflix, in addition to Amazon) have granted their permission for the works to be made available via Nyaa or the BitTorrent network(s) that underpin it. As a result, "significant, irreparable damage" has already been caused to the copyright owners by the site's activities. While emailed threats are still a common anti-piracy strategy, we are informed that at least two of the individuals were personally served with legal documents at their homes. Others were served with similar documents via regular mail. We are currently unable to determine exactly how many people were served in total. At the moment the suggestion is around five but that may not be the full picture. What we do know is that some or all stand accused of being part of the mysterious 'Anime Cartel' supposedly behind Nyaa. "With immediate effect, recipients have been told to take all necessary steps to ensure that Nyaa is completely shut down," the report adds. "The MPA also wants to take control of the site's domain -- Nyaa.si -- a common tactic in other anti-piracy actions. Overall, recipients are warned that they must cease-and-desist any and all of their activities related to the site, including making available the copyrighted works of the MPA's members."

"In addition to receiving settlements, it appears that the MPA also wants information on the Nyaa service and its operations. The MPA also wants the rights to the Nyaa site and any technologies connected to it, wherever the recipient has the ability to transfer those rights. The MPA also demands that those entering into a settlement agreement should never infringe its members' rights again."
