A prominent journal has decided to retract a paper by Ranga Dias, a physicist at the University of Rochester in New York who has made controversial claims about discovering room-temperature superconductors -- materials that would not require any cooling to conduct electricity with zero resistance. From a report: The forthcoming retraction, of a paper published by Physical Review Letters (PRL) in 20211, is significant because the Nature news team has learnt that it is the result of an investigation that found apparent data fabrication. PRL's decision follows allegations that Dias plagiarized substantial portions of his PhD thesis and a separate retraction of one of Dias's papers on room-temperature superconductivity by Nature last September.

After receiving an e-mail last year expressing concern about possible data fabrication in Dias's PRL paper -- a study, not about room-temperature superconductivity, but about the electrical properties of manganese disulfide (MnS2) -- the journal commissioned an investigation by four independent referees. Nature's news team has obtained documents about the investigation, including e-mails and three reports of its outcome, from sources who have asked to remain anonymous. "The findings back up the allegations of data fabrication/falsification convincingly," PRL's editors wrote in an e-mail obtained by Nature.

Google and Apple dominate the market for online maps, charging mobile app developers for access to their mapping services. The other mega-cap tech companies are joining together to help create another option. From a report: A group formed by Meta, Microsoft and Amazon Web Services, along with TomTom, is releasing data that could enable companies to build their own maps, without having to rely on Google or Apple. The Overture Maps Foundation, which was established late last year, captured 59 million "points of interest," such as restaurants, landmarks, streets and regional borders. The data has been cleaned and formatted so it can be used for free as the base layer for a new map application.

Meta and Microsoft collected and donated the data to Overture, according to Marc Prioleau, executive director of the OMF. Data on places is often difficult to collect and license, and building map data requires lots of time and staff to gather and clean it, he told CNBC in an interview. "We have some companies that, if they wanted to invest to build the map data, they could," Prioleau said. Rather than spending that kind of money, he said, companies were asking, "Can we just get collaboration around the open base map?" Overture is aiming to establish a baseline for maps data so that companies can use it to build and operate their own maps.

Smartphones should be banned from schools to tackle classroom disruption, improve learning and help protect children from cyberbullying, a UN report has recommended. From a report: Unesco, the UN's education, science and culture agency, said there was evidence that excessive mobile phone use was linked to reduced educational performance and that high levels of screen time had a negative effect on children's emotional stability. It said its call for a smartphone ban sent a clear message that digital technology as a whole, including artificial intelligence, should always be subservient to a "human-centred vision" of education, and never supplant face-to-face interaction with teachers.

Unesco warned policymakers against an unthinking embrace of digital technology, arguing that its positive impact on learning outcomes and economic efficiency could be overstated, and new was not always better. "Not all change constitutes progress. Just because something can be done does not mean it should be done," it concluded. With more learning moving online, especially in universities, it urged policymakers not to neglect the "social dimension" of education where students receive face-to-face teaching. "Those urging increasing individualisation may be missing the point of what education is about," it said.

The tech giant and the Wall Street titan went from "the most successful credit card launch ever" to Goldman trying to exit the partnership. From a report: Apple and Goldman Sachs were in test runs before embarking publicly on one of the biggest-name partnerships ever between tech and finance. Engineers from the Silicon Valley giant and the Wall Street titan were pulling an all-nighter a few months before launch, scrambling to find a solution to a problem that had cropped up: Tim Cook couldn't get approved for an Apple Card.

Apple and Goldman had struck the powerful alliance as they set out to build a revolutionary digital-first credit card with designs on expanding into other consumer finance products. For Goldman, it was a key opportunity to grow the consumer business it had jumped into as it sought to diversify away from the old-school Wall Street revenue model of trading and advising on deals. For Apple, it was a way to bolster its services business, broaden its finance offerings -- which began with Apple Pay -- and, maybe most importantly, prompt people to buy more iPhones.

In October 2019, a couple of months after customers began signing up, Goldman CEO David Solomon described it as "the most successful credit card launch ever." Less than four years later -- and only a handful of months after the two companies extended their contract through the end of the decade -- the Apple-Goldman deal is teetering. Some of the partnership's shortcomings have blemished both companies' world-class reputations, and a falling-out could threaten future collaboration between Wall Street and tech at large. Goldman has been trying to get out of the pact because it won't be profitable enough for the bank in the near term, according to people familiar with the matter, and it has shopped the relationship to credit card issuer American Express.

Amazon's Clubhouse rival, Amp, has struggled to get off the ground, documents shared with TechCrunch show. From the report: As part of the launch in March 2022, Amazon announced a slate of Amp-exclusive shows and programs, including from artists, radio hosts, sportscasters, culture writers and personalities like Nicki Minaj ("Queen Radio"), Tefi Pessoa and Guy Raz, among others. Amp launched on iOS, Amazon Alexa devices and the web in beta, only in the U.S. to start. Amazon was targeted at over 1 million monthly active users by the end of 2022, according to internal documents -- a tenth of Clubhouse's user base at its peak. But Amp never came close to achieving that milestone.

Amp, which had roughly 32,000 monthly active users as of the end of March 2022, was sitting just short of 200,000 monthly active users by late October. (A source tells TechCrunch that the number is hovering around 700,000 today.) From September 2022 to October 2022, monthly first-time iOS app installs declined precipitously from ~76,000 to ~43,000, internal documents show. And Amp encountered roadblocks on the engagement front, despite its lineup of high-profile content. Between September 2022 and October 2022, the number of hours users spent listening to Amp shows dipped 51% from a peak of around 183,000. Even without access to internal data, it's obvious that Amp isn't the most active of the live audio platforms cohort.

Chairwoman Jessica Rosenworcel of the Federal Communications Commission proposes a new broadband standard of 100Mbps downloads and 20Mbps uploads, replacing the 2015's 25Mbps/3Mbps metric. From a report: "In today's world, everyone needs access to affordable, high-speed Internet, no exceptions," Rosenworcel said in the announcement today. "It's time to connect everyone, everywhere. Anything short of 100 percent is just not good enough." Section 706 of the Telecommunications Act requires the FCC to determine whether broadband is being deployed "on a reasonable and timely basis" to all Americans. If the answer is no, the US law says the FCC must "take immediate action to accelerate deployment of such capability by removing barriers to infrastructure investment and by promoting competition in the telecommunications market."

The FCC's previous Section 706 reports analyzed availability and included data on adoption but didn't consider affordability. In her announcement today, Rosenworcel said she "recently shared with her colleagues an updated Notice of Inquiry that would kick off the agency's evaluation of the state of broadband across the country, as required by Section 706 of the Telecommunications Act. Chairwoman Rosenworcel proposes that the Commission consider several crucial characteristics of broadband deployment, including affordability, adoption, availability, and equitable access, when determining whether broadband is being deployed in a reasonable and timely fashion to 'all Americans.'"

The Federal Trade Commission is finalizing its long-awaited antitrust lawsuit against Amazon, POLITICO reported Tuesday, citing people with knowledge of the matter, a move that could ultimately break up parts of the company. From the report: The FTC has been investigating the company on a number of fronts, and the coming case would be one of the most aggressive and high-profile moves in the Biden administration's rocky effort to tame the power of tech giants. The wide-ranging lawsuit is expected as soon as August, and will likely challenge a host of Amazon's business practices, said the people, who were granted anonymity to discuss a confidential matter. If successful, it could lead to a court-ordered restructuring of the $1.3 trillion empire and define the legacy of FTC Chair Lina Khan.

Khan rose to prominence as a Big Tech skeptic with a 2017 academic paper specifically identifying Amazon as a modern monopolist needing to be reined in. Because any case will likely take years to wind through the courts, the final result will rest with her successors. The exact details of the final lawsuit are not known, and changes to the final complaint are expected until the eleventh hour. But personnel throughout the agency, including Khan herself, have homed in on several of Amazon's business practices, said some of the people.

Following two years of testing, The Browser Company's Arc is graduating from its waitlist phase, launching its version 1.0. Arc, the Mac and iOS browser, aims to redefine online interaction by incorporating tools for note-taking, collaboration, webpage personalisation, among others. The Verge adds: We've covered Arc a lot in recent months, both because it's a good browser and because it's a big new idea about how you use the internet. The Browser Company's ultimate plan is to build "the operating system for the internet." Arc isn't just a place to see webpages; it has tools for taking notes, making visual and collaborative easels with others, redesigning webpages to your liking, and more. (Personally, I love Arc's picture-in-picture mode above everything else, especially now that it works with Google Meet calls.) Arc 1.0 doesn't seem to come with any splashy new features. Rather, The Browser Company seems to just feel like it's ready to launch more widely. Arc has been pretty stable for me in recent months, though it does run into some of the same performance issues you'll find with any browser based on the Chromium engine -- you can always open a couple dozen tabs and watch your computer grind to a halt.

An anonymous reader shares a report: In January, artificial intelligence powerhouse OpenAI announced a tool that could save the world -- or at least preserve the sanity of professors and teachers -- by detecting whether a piece of content had been created using generative AI tools like its own ChatGPT. Half a year later, that tool is dead, killed because it couldn't do what it was designed to do.

ChatGPT creator OpenAI quietly unplugged its AI detection tool, AI Classifier, last week because of "its low rate of accuracy," the firm said. The explanation was not in a new announcement, but added in a note added to the blog post that first announced the tool. The link to OpenAI's classifier is no longer available. "We are working to incorporate feedback and are currently researching more effective provenance techniques for text, and have made a commitment to develop and deploy mechanisms that enable users to understand if audio or visual content is AI-generated," OpenAI wrote.

The Gulf Stream system could collapse as soon as 2025, a new study suggests. The shutting down of the vital ocean currents, called the Atlantic Meridional Overturning Circulation (Amoc) by scientists, would bring catastrophic climate impacts. From a report: Amoc was already known to be at its weakest in 1,600 years owing to global heating and researchers spotted warning signs of a tipping point in 2021. The new analysis estimates a timescale for the collapse of between 2025 and 2095, with a central estimate of 2050, if global carbon emissions are not reduced. Evidence from past collapses indicate changes of temperature of 10C in a few decades, although these occurred during ice ages.

Other scientists said the assumptions about how a tipping point would play out and uncertainties in the underlying data are too large for a reliable estimate of the timing of the tipping point. But all said the prospect of an Amoc collapse was extremely concerning and should spur rapid cuts in carbon emissions. Amoc carries warm ocean water northwards towards the pole where it cools and sinks, driving the Atlantic's currents. But an influx of fresh water from the accelerating melting of Greenland's ice cap and other sources is increasingly smothering the currents.

Google Street View's cameras have returned to Germany more than a decade after a privacy backlash in the country pushed it to stop updating images. From a report: Alphabet's update will start with new photos of the streets and landmarks of the country's 20 largest cities and expand from there, the company said in a blog post on Tuesday. Google voluntarily suspended Street View photography in Germany in 2011, after an outcry from privacy advocates and opposition from regulators.

"We've been back on the road with our vehicles in Germany since June and will be posting the latest images as they become available -- adding footage from other regions across the country," Sven Tresp, a program manager for Street View, wrote. Google is posting information about where its cameras are traveling, he said. The Street View rollout across Europe more than a decade ago triggered probes by data protection watchdogs across the European Union. The investigations included a probe by the Hamburg authority, where Google had its main German base. Some led to fines, including a $1.1 million penalty in Italy.

The Council of the EU has adopted new rules intended to make it much easier for EV owners to travel across Europe, while simultaneously helping to reduce the output of harmful greenhouse gases. From a report: The new regulation is set to benefit owners of electric cars and vans in three ways: It reduces range anxiety by expanding the EV charging infrastructure along Europe's main highways, it makes payments "at the pump" easier without requiring an app or subscription, and ensures pricing and availability is clearly communicated to avoid surprises. From 2025 onward, the new regulation requires fast charging stations offering at least 150kW of power to be installed every 60km (37mi) along the EU's Trans-European Transport Network, or (TEN-T) system of highways, the bloc's main transport corridor. The fast charging network along European highways is already pretty robust, I discovered on a recent 3,000km (2,000 mile) roadtrip with a VW ID Buzz. This new law could all but eliminate range anxiety for those sticking to TEN-T roads.

Chainalysis' head of investigations doesn't seem to have a great understanding of whether her company's flagship software even works. From a report: Elizabeth Bisbee, head of investigations at Chainalysis Government Solutions, testified she was "unaware" of scientific evidence for the accuracy of Chainalysis' Reactor software used by law enforcement, an unreleased transcript of a June 23 hearing shared with CoinDesk shows.

The fact that Chainalysis' blockchain demystification tools have become so widespread is a serious threat to the crypto ecosystem. Although industry insiders have raged against Chainalysis since it was founded, often accusing it of violating people's financial privacy, there may be a better argument to make against the company and analysis firms like it: it's within the realm of possibility that these "probabilistic" machines don't work as well as advertised. This is a big deal considering Chainalysis' surveillance tools are used widely across the industry for compliance, and have at times led to unjustified account restrictions and -- even worse -- land unsuspecting individuals on the radar of law enforcement agencies without probable cause.

Google's newest proposed web standard is... DRM? Over the weekend the Internet got wind of this proposal for a "Web Environment Integrity API. " From a report: The explainer is authored by four Googlers, including at least one person on Chrome's "Privacy Sandbox" team, which is responding to the death of tracking cookies by building a user-tracking ad platform right into the browser. The intro to the Web Integrity API starts out: "Users often depend on websites trusting the client environment they run in. This trust may assume that the client environment is honest about certain aspects of itself, keeps user data and intellectual property secure, and is transparent about whether or not a human is using it."

The goal of the project is to learn more about the person on the other side of the web browser, ensuring they aren't a robot and that the browser hasn't been modified or tampered with in any unapproved ways. The intro says this data would be useful to advertisers to better count ad impressions, stop social network bots, enforce intellectual property rights, stop cheating in web games, and help financial transactions be more secure. Perhaps the most telling line of the explainer is that it "takes inspiration from existing native attestation signals such as [Apple's] App Attest and the [Android] Play Integrity API." Play Integrity (formerly called "SafetyNet") is an Android API that lets apps find out if your device has been rooted.

Root access allows you full control over the device that you purchased, and a lot of app developers don't like that. So if you root an Android phone and get flagged by the Android Integrity API, several types of apps will just refuse to run. You'll generally be locked out of banking apps, Google Wallet, online games, Snapchat, and some media apps like Netflix. [...] Google wants the same thing for the web. Google's plan is that, during a webpage transaction, the web server could require you to pass an "environment attestation" test before you get any data. At this point your browser would contact a "third-party" attestation server, and you would need to pass some kind of test. If you passed, you would get a signed "IntegrityToken" that verifies your environment is unmodified and points to the content you wanted unlocked. You bring this back to the web server, and if the server trusts the attestation company, you get the content unlocked and finally get a response with the data you wanted.

The European Union's plan to bolster domestic semiconductor production will become law after ministers completed the final approval on Tuesday. From a report: The EU's Chips Act, which was approved by the European Parliament earlier this month, will take effect once it's published in the bloc's Official Journal. The European Commission first proposed the $47.5 billion Chips Act as part of an ambitious goal of producing 20% of the world's semiconductors by 2030. Numerous companies, including Intel and STMicroelectronics, have already announced new sites in Europe.
