Starlink Launches First 'Cellphone Towers In Space' For Use with LTE Phones (arstechnica.com) 38

SpaceX launched a total of 21 satellites on Tuesday night, including "the first six Starlink satellites with Direct to Cell capabilities that enable mobile network operators around the world to provide seamless global access to texting, calling, and browsing wherever you may be on land, lakes, or coastal waters without changing hardware or firmware. The enhanced Starlink satellites have an advanced modem that acts as a cellphone tower in space, eliminating dead zones with network integration similar to a standard roaming partner," the company said. Ars Technica reports: Besides T-Mobile in the US, several carriers in other countries have signed up to use the direct-to-cell satellites. SpaceX said the other carriers are Rogers in Canada, KDDI in Japan, Optus in Australia, One NZ in New Zealand, Salt in Switzerland, and Entel in Chile and Peru. While SpaceX CEO Elon Musk wrote that the satellites will "allow for mobile phone connectivity anywhere on Earth," he also described a significant bandwidth limit. "Note, this only supports ~7Mb per beam and the beams are very big, so while this is a great solution for locations with no cellular connectivity, it is not meaningfully competitive with existing terrestrial cellular networks," Musk wrote.

Starlink's direct-to-cell website says the service will provide text messaging only when it becomes available in 2024, with voice and data service beginning sometime in 2025. Starlink's low Earth orbit satellites will work with standard LTE phones, unlike earlier services that required phones specifically built for satellite use. SpaceX's direct-to-cell satellites will also connect with Internet of Things (IoT) devices in 2025, the company says.

Reckless DMCA Deindexing Pushes NASA's Artemis Towards Black Hole (torrentfreak.com) 83

Andy Maxwell reports via TorrentFreak: As the crew of Artemis 2 prepare to become the first humans to fly to the moon since 1972, the possibilities of space travel are once again igniting imaginations globally. More than 92% of internet users who want to learn more about this historic mission and the program in general are statistically likely to use Google search. Behind the scenes, however, the ability to find relevant content is under attack. Blundering DMCA takedown notices sent by a company calling itself DMCA Piracy Prevention Inc. claim to protect the rights of an OnlyFans/Instagram model working under the name 'Artemis'. Instead, keyword-based systems that fail to discriminate between copyright-infringing content and that referencing the word Artemis in any other context, are flooding towards Google. They contain demands to completely deindex non-infringing, unrelated content, produced by innocent third parties all over the world.

A recent deindexing demand dated December 13, 2022, lists DMCA Piracy Prevention Inc. of Canada as the sender. The name of the content owner is redacted but the notice itself states that the company represents a content creator performing under the name Artemis. The notice demands the removal of 3,617 URLs from Google search. If successful, those URLs would be completely unfindable by more than 92% of the world's population who use that search engine. [...] At least 9 of the first 20 URLs in the notice demand the removal of non-infringing articles and news reports referencing the Artemis space program. None have anything to do with the content the sender claims to protect. [...]

Theories as to who might own and/or operate DMCA Piracy Prevention Inc. aren't hard to find but the company does exist and is registered as a corporate entity in Canada. Registered at the same address is a company with remarkably similar details. BranditScan is a corporate entity operating in exactly the same market offering similar if not identical services. BranditScan has sent DMCA takedown notices to Google under three different notifier accounts.

Earth Was Due for Another Year of Record Warmth. But This Warm? (nytimes.com) 205

Earth is finishing up its warmest year in the past 174 years, and very likely the past 125,000. From a report: Unyielding heat waves broiled Phoenix and Argentina. Wildfires raged across Canada. Flooding in Libya killed thousands. Wintertime ice cover in the dark seas around Antarctica was at unprecedented lows. This year's global temperatures did not just beat prior records. They left them in the dust. From June through November, the mercury spent month after month soaring off the charts. December's temperatures have largely remained above normal: Much of the Northeastern United States is expecting springlike conditions this week.

That is why scientists are already sifting through evidence -- from oceans, volcanic eruptions, even pollution from cargo ships -- to see whether this year might reveal something new about the climate and what we are doing to it. One hypothesis, perhaps the most troubling, is that the planet's warming is accelerating, that the effects of climate change are barreling our way more quickly than before. "What we're looking for, really, is a bunch of corroborating evidence that all points in the same direction," said Chris Smith, a climate scientist at the University of Leeds. "Then we're looking for causality. And that will be really interesting."

'Doctor Who' Christmas Special Streams on Disney+ and the BBC (cnet.com) 65

An anonymous Slashdot reader shared this report from CNET: Marking its 60th year on television, the British time-travel series will close out 2023 with one last anniversary special that arrives on Christmas Day. Ncuti Gatwa's Doctor helms the Tardis in The Church on Ruby Road, which centers on an abandoned baby who grows up looking for answers... Disney Plus will stream Doctor Who: The Church on Ruby Road on Monday, Dec. 25, at 12:55 p.m. ET (9:55 a.m. PT) in all regions except the UK and Ireland, where it will air on the BBC. In case you missed it, viewers can also watch David Tennant starring in the other three anniversary specials: The Star Beast, Wild Blue Yonder and The Giggle. All releases are available on Disney Plus.
But what's interesting is CNET goes on to explain "why a VPN could be a useful tool." Perhaps you're traveling abroad and want to stream Disney Plus while away from home. With a VPN, you're able to virtually change your location on your phone, tablet or laptop to get access to the series from anywhere in the world. There are other good reasons to use a VPN for streaming too. A VPN is the best way to encrypt your traffic and stop your ISP from throttling your speeds...

You can use a VPN to stream content legally as long as VPNs are allowed in your country and you have a valid subscription to the streaming service you're using. The U.S. and Canada are among the countries where VPNs are legal

US Commits To Landing an International Astronaut On the Moon (arstechnica.com) 49

During a meeting of the National Space Council, Vice President Kamala Harris said an international astronaut will land on the Moon during one of NASA's Artemis missions. "Today, in recognition of the essential role that our allies and partners play in the Artemis program, I am proud to announce that alongside American astronauts, we intend to land an international astronaut on the surface of the Moon by the end of the decade," Harris said. Ars Technica reports: Although the National Space Council is useful in aggregating disparate interests across the US government to help form more cohesive space policies, public meetings like the one Wednesday can seem perfunctory. Harris departed the stage soon after her speech, and other government officials read from prepared remarks during the rest of the event. Nevertheless, Harris' announcement highlighted the role the space program plays in elevating the soft power of the United States. It was widely assumed an international astronaut would eventually land on the Moon with NASA. Harris put a deadline on achieving this goal.

NASA has long included astronauts from its international partners on human spaceflight missions, dating back to the ninth flight of the space shuttle in 1983, when West German astronaut Ulf Merbold joined five Americans on a flight to low-Earth orbit. This was seen by US government officials as a way to foster closer relations with like-minded countries. The inclusion of foreign astronauts on US missions also repays partner nations who make financial commitments to US-led space projects with a high-profile flight opportunity for one of their citizens.

Among the international partners contributing to Artemis, it seems most likely a European astronaut would get the first slot for a landing with NASA. ESA funded the development of the service modules used on NASA's Orion spacecraft, which will ferry astronauts from Earth to the Moon and back. These modules provide power and propulsion for Orion. ESA is also developing refueling and communications infrastructure for the Gateway mini-space station to be constructed in orbit around the Moon.

A Japanese astronaut might also have a shot at getting a seat on an Artemis landing. Japan's government has committed to providing the life-support system for the Gateway's international habitation module, along with resupply services to deliver cargo to Gateway. Japan is also interested in building a pressurized rover for astronauts to drive across the lunar surface. In recognition of Japan's contributions, NASA last year committed to flying a Japanese astronaut aboard Gateway. Canada is building a robotic arm for Gateway, but a Canadian astronaut already has a seat on NASA's first crewed Artemis mission, albeit without a trip to the lunar surface.

Canada Lays Out Plan To Phase Out Sales of Gas-Powered Cars, Trucks By 2035 (www.cbc.ca) 405

"EVs mandates are coming to Canada whether you like it or not," writes Slashdot reader Major_Disorder, sharing a report from the Canadian Broadcasting Corporation. "Here is what my Canadian brothers and sisters need to know." From the report: New regulations being published this week by Environment Minister Steven Guilbeault will effectively end sales of new passenger vehicles powered only by gasoline or diesel in 2035. Guilbeault said the Electric Vehicle Availability Standard will encourage automakers to make more battery-powered cars and trucks available in Canada. "There's no mistaking it. We are at a tipping point," he said, noting sizable growth in EV sales in Canada and demand that has previously outstripped the available supply.

Automakers will have the next 12 years to phase out combustion engine cars, trucks and SUVs with a requirement to gradually increase the proportion of electric models they offer for sale each year. The electric-vehicle sales mandate regulations will be published later this week. They are setting up a system in which every automaker will have to show that a minimum percentage of vehicles they offer for sale are fully electric or longer-range plug-in hybrids. It will start with 20 per cent in 2026 and rise slightly to 23 per cent in 2027. After that, the share of EVs will begin to increase much faster, so that by 2028, 34 per cent of all vehicles sold will need to be electric -- 43 per cent by 2029 and 60 per cent by 2030. That number keeps rising until it hits 100 per cent in 2035.

Guilbeault said the government is working to revise the national building code to encourage the spread of charging stations. The updated code would ensure that residential buildings constructed after 2025 have the electrical capacity to accommodate the charging stations. [...] The policy will be regulated under the Canadian Environmental Protection Act and will issue credits to automakers for the EVs they sell. Generally, a fully electric model will generate one credit, with plug-in hybrids getting partial or full credit depending on how far they can go on a single charge. Manufacturers that sell more EVs than they need to meet each year's target can either bank those credits to meet their targets in future years, or sell them to companies that didn't sell enough. They can also cover up to 10 per cent of the credits they need each year by investing in public fast-charging stations. Every $20,000 spent on DC fast chargers that are operating before 2027 can earn the equivalent of one credit. Automakers that come up short for their sales requirements will be able to cover the difference by buying credits from others who exceed their targets, or by investing in charging stations. Automakers can start earning some credits toward their 2026 and 2027 targets over the next two years -- a bid by the government to encourage a faster transition.

Meta's News Ban In Canada Remains As Online News Act Goes Into Effect (bbc.com) 147

An anonymous reader quotes a report from the BBC: A bill that mandates tech giants pay news outlets for their content has come into effect in Canada amid an ongoing dispute with Facebook and Instagram owner Meta over the law. Some have hailed it as a game-changer that sets out a permanent framework that will see a steady drip of funds from wealthy tech companies to Canada's struggling journalism industry. But it has also been met with resistance by Google and Meta -- the only two companies big enough to be encompassed by the law. In response, over the summer, Meta blocked access to news on Facebook and Instagram for Canadians. Google looked set to follow, but after months of talks, the federal government was able to negotiate a deal with the search giant as the company has agreed to pay Canadian news outlets $75 million annually.

No such agreement appears to be on the horizon with Meta, which has called the law "fundamentally flawed." If Meta is refusing to budge, so is the government. "We will continue to push Meta, that makes billions of dollars in profits, even though it is refusing to invest in the journalistic rigor and stability of the media," Prime Minister Justin Trudeau told reporters on Friday.
According to a study by the Media Ecosystem Observatory, the views of Canadian news on Facebook dropped 90% after the company blocked access to news on the platform. Local news outlets have been hit particularly hard.

"The loss of journalism on Meta platforms represents a significant decline in the resiliency of the Canadian media ecosystem," said Taylor Owen, a researcher at McGill and the co-author of the study. He believes it also hurts Meta's brand in the long run, pointing to the fact that the Canada's federal government, as well as that of British Columbia, other municipalities and a handful of large Canadian corporations, have all pulled their advertising off Facebook and Instagram in retaliation.

Could 'Godzilla Minus One' Win an Oscar? (cinemablend.com) 70

ScreenRant reports that on December 4, "Godzilla Minus One" was the #1 movie in the crucial U.S./Canada "domestic" market (which also includes Guam and Puerto Rico). But the next week was even more impressive, reports Forbes, retaining most of its box office figure with "an incredibly strong 90% hold across the three-day Friday-Saturday-Sunday frame, for what appears to be the best second weekend hold for a wide release in 2023." Through the week, Godzilla Minus One topped the North American charts four out of five weekdays on overwhelmingly positive word of mouth. Good buzz grew through the week as more viewers and critics saw and recommend the film... Godzilla Minus One is already the highest grossing Japanese live-action release of all time in the U.S. The film is a final contender for the Academy Award nominations for Best Visual Effects, and is widely expected to be one of the final official nominees.
CinemaBlend believes the movie should be nominated for this year's Best Picture award at the Oscars. With a total of 105 critical reviews (at the time of this writing), Godzilla Minus One has a Tomatometer score of 97%...

Godzilla has literally been a metaphor for the atomic bomb since the very beginning. However, Godzilla Minus One isn't as concerned with that idea. Instead, the story is all about sacrifice as well as the hope we have for future generations. It's a story of coming together and living for today, so that our children can be inspired to want to live for tomorrow. The Takashi Yamazaki-helmed feature doesn't present a story about destruction, but rather one about wanting peace and finding conducive ways to deal with trauma. I know you might not believe me if you haven't seen it yet, but the film is just as deep and "important" as Oppenheimer and, for that, it should be nominated.

They argue the movie manages to be both "a layered film" and "a popcorn flick...

"it's more than JUST a film featuring a giant reptile This one actually has something to say."

Reactions Continue to Viral Video that Led to Calls for College Presidents to Resign 414

After billionaire Bill Ackman demanded three college presidents "resign in disgrace," that post on X — excerpting their testimony before a U.S. Congressional committee — has now been viewed more than 104 million times, provoking a variety of reactions.

Saturday afternoon, one of the three college presidents resigned — University of Pennsylvania president Liz Magill.

Politico reports that the Republican-led Committee now "will be investigating Harvard University, MIT and the University of Pennsylvania after their institutions' leaders failed to sufficiently condemn student protests calling for 'Jewish genocide.'" The BBC reports a wealthy UPenn donor reportedly withdrew a stock grant worth $100 million.

But after watching the entire Congressional hearing, New York Times opinion columnist Michelle Goldberg wrote that she'd seen a "more understandable" context: In the questioning before the now-infamous exchange, you can see the trap [Congresswoman Elise] Stefanik laid. "You understand that the use of the term 'intifada' in the context of the Israeli-Arab conflict is indeed a call for violent armed resistance against the state of Israel, including violence against civilians and the genocide of Jews. Are you aware of that?" she asked Claudine Gay of Harvard. Gay responded that such language was "abhorrent."

Stefanik then badgered her to admit that students chanting about intifada were calling for genocide, and asked angrily whether that was against Harvard's code of conduct. "Will admissions offers be rescinded or any disciplinary action be taken against students or applicants who say, 'From the river to the sea' or 'intifada,' advocating for the murder of Jews?" Gay repeated that such "hateful, reckless, offensive speech is personally abhorrent to me," but said action would be taken only "when speech crosses into conduct." So later in the hearing, when Stefanik again started questioning Gay, Kornbluth and Magill about whether it was permissible for students to call for the genocide of the Jews, she was referring, it seemed clear, to common pro-Palestinian rhetoric and trying to get the university presidents to commit to disciplining those who use it. Doing so would be an egregious violation of free speech. After all, even if you're disgusted by slogans like "From the river to the sea, Palestine will be free," their meaning is contested...

Liberal blogger Josh Marshall argues that "While groups like Hamas certainly use the word [intifada] with a strong eliminationist meaning it is simply not the case that the term consistently or usually or mostly refers to genocide. It's just not. Stefanik's basic equation was and is simply false and the university presidents were maladroit enough to fall into her trap."

The Wall Street Journal published an investigation the day after the hearing. A political science professor at the University of California, Berkeley hired a survey firm to poll 250 students across the U.S. from "a variety of backgrounds" — and the results were surprising: A Latino engineering student from a southern university reported "definitely" supporting "from the river to the sea" because "Palestinians and Israelis should live in two separate countries, side by side." Shown on a map of the region that a Palestinian state would stretch from the Jordan River to the Mediterranean Sea, leaving no room for Israel, he downgraded his enthusiasm for the mantra to "probably not." Of the 80 students who saw the map, 75% similarly changed their view... In all, after learning a handful of basic facts about the Middle East, 67.8% of students went from supporting "from the river to the sea" to rejecting the mantra. These students had never seen a map of the Mideast and knew little about the region's geography, history, or demography.
More about the phrase from the Associated Press: Many Palestinian activists say it's a call for peace and equality after 75 years of Israeli statehood and decades-long, open-ended Israeli military rule over millions of Palestinians. Jews hear a clear demand for Israel's destruction... By 2012, it was clear that Hamas had claimed the slogan in its drive to claim land spanning Israel, the Gaza Strip and the West Bank... The phrase also has roots in the Hamas charter... [Since 1997 the U.S. government has considered Hamas a terrorist organization.]

"A Palestine between the river to the sea leaves not a single inch for Israel," read an open letter signed by 30 Jewish news outlets around the world and released on Wednesday... Last month, Vienna police banned a pro-Palestinian demonstration, citing the fact that the phrase "from the river to the sea" was mentioned in invitations and characterizing it as a call to violence. And in Britain, the Labour party issued a temporary punishment to a member of Parliament, Andy McDonald, for using the phrase during a rally at which he called for a stop to bombardment.

As the controversy rages on, Ackman's X timeline now includes an official response reposted from a college that wasn't called to testify — Stanford University: In the context of the national discourse, Stanford unequivocally condemns calls for the genocide of Jews or any peoples. That statement would clearly violate Stanford's Fundamental Standard, the code of conduct for all students at the university.
Ackman also retweeted this response from OpenAI CEO Sam Altman: for a long time i said that antisemitism, particularly on the american left, was not as bad as people claimed. i'd like to just state that i was totally wrong. i still don't understand it, really. or know what to do about it. but it is so fucked.
Wednesday UPenn's president announced they'd immediately consider a new change in policy," in an X post viewed 38.7 million times: For decades under multiple Penn presidents and consistent with most universities, Penn's policies have been guided by the [U.S.] Constitution and the law. In today's world, where we are seeing signs of hate proliferating across our campus and our world in a way not seen in years, these policies need to be clarified and evaluated. Penn must initiate a serious and careful look at our policies, and provost Jackson and I will immediately convene a process to do so. As president, I'm committed to a safe, secure, and supportive environment so all members of our community can thrive. We can and we will get this right. Thank you.
The next day the university's business school called on Magill to resign. And Saturday afternoon, Magill resigned.

Amazon Says Thieves Swiped Millions by Faking Product Refunds (bloomberg.com) 26

Amazon sued what it called an international ring of thieves who swiped millions of dollars in merchandise from the company through a series of refund scams that included buying products on Amazon and seeking refunds without returning the goods. From a report: An organization called REKK advertised its refund services on social media sites, including Reddit and Discord, and communicated with perpetrators on the messaging app Telegram, Amazon said in a lawsuit filed Thursday in US District Court in the state of Washington.

The lawsuit names REKK and nearly 30 people from the US, Canada, UK, Greece, Lithuania and the Netherlands as defendants in the scheme, which involved hacking into Amazon's internal systems and bribing Amazon employees to approve reimbursements. REKK charged customers, who wanted to get pricey items like MacBook Pro laptops and car tires without paying for them, a commission based on the value of the purchase. "The defendants' scheme tricks Amazon into processing refunds for products that are never returned; instead of returning the products as promised, defendants keep the product and the refund," Amazon said in its lawsuit.

Apple Report Finds Steep Increase in Data Breaches, Ransomware (axios.com) 12

Data breaches and ransomware attacks are getting worse. Some 2.6 billion personal records have been exposed in data breaches over the past two years and that number continues to grow, according to a new report commissioned by Apple. From a report: Apple says the escalating intrusions, combined with increases in ransomware means the tech industry needs to move toward greater use of encryption. According to the report, prepared by MIT professor emeritus Stuart E. Madnick:

1. Data breaches in the US through the first nine months of the year are already 20% higher than for all of 2022.
2. Nearly 70 percent more ransomware attacks were reported through September 2023, than in the first three quarters of 2022.
3. Americans and those in the UK topped the list of those most targeted in ransomware attacks in 2023, followed by Canada and Australia. Those four countries accounted for nearly 70% of reported ransomware attacks.
4. One in four people in the US had their health data exposed in a data breach during the first nine months of 2023.

The Extremely Large Telescope Will Transform Astronomy (economist.com) 35

The Extremely Large Telescope (ELT) under construction in Chile's Atacama Desert will be the world's biggest optical telescope when completed in 2028. With a giant 39.3-meter main mirror and advanced adaptive optics, the ELT will collect far more light and achieve much sharper images than any existing ground-based telescope, revolutionizing the study of exoplanets, black holes, dark matter, and the early universe. Economist adds: But when it comes to detecting the dimmest and most distant objects, there is no substitute for sheer light-gathering size. On that front the ELT looks like being the final word for the foreseeable future. A planned successor, the "Overwhelmingly Large Telescope," would have sported a 100-metre mirror. But it was shelved in the 2000s on grounds of complexity and cost. The Giant Magellan Telescope is currently being built several hundred kilometres south of the elt on land owned by the Carnegie Institution for Science, an American non-profit, and is due to see its first light some time in the 2030s. It will combine seven big mirrors into one giant one with an effective diameter of 25.4 metres. Even so, it will have only around a third the light-gathering capacity of the ELT.

A consortium of scientists from America, Canada, India and Japan, meanwhile, has been trying to build a mega-telescope on Hawaii. The Thirty Meter Telescope would, as its name suggests, be a giant -- though still smaller than the elt. But it is unclear when, or even if, it will be finished. Construction has been halted by arguments about Mauna Kea, the mountain on which it is to be built, which is seen as sacred by some. For the next several decades, it seems, anyone wanting access to the biggest telescope money can buy will have to make their way to northern Chile.

Millions of Coders Are Now Using AI Assistants. How Will That Change Software? (technologyreview.com) 78

AI coding assistants are here to stay -- but just how big a difference they make is still unclear. From a report: Thomas Dohmke, GitHub's CEO: "You've got a lot of tabs open, you're planning a vacation, maybe you're reading the news. At last you copy the text you need and go back to your code, but it's 20 minutes later and you lost the flow." The key idea behind Copilot and other programs like it, sometimes called code assistants, is to put the information that programmers need right next to the code they are writing.

The tool tracks the code and comments (descriptions or notes written in natural language) in the file that a programmer is working on, as well as other files that it links to or that have been edited in the same project, and sends all this text to the large language model behind Copilot as a prompt. (GitHub co-developed Copilot's model, called Codex, with OpenAI. It is a large language model fine-tuned on code.) Copilot then predicts what the programmer is trying to do and suggests code to do it. This round trip between code and Codex happens multiple times a second, the prompt updating as the programmer types. At any moment, the programmer can accept what Copilot suggests by hitting the tab key, or ignore it and carry on typing. The tab button seems to get hit a lot. A study of almost a million Copilot users published by GitHub and the consulting firm Keystone Strategy in June -- a year after the tool's general release -- found that programmers accepted on average around 30% of its suggestions, according to GitHub's user data.

[...] Copilot has changed the basic skills of coding. As with ChatGPT or image makers like Stable Diffusion, the tool's output is often not exactly what's wanted -- but it can be close. "Maybe it's correct, maybe it's not -- but it's a good start," says Arghavan Moradi Dakhel, a researcher at Polytechnique Montreal in Canada who studies the use of machine-learning tools in software development. Programming becomes prompting: rather than coming up with code from scratch, the work involves tweaking half-formed code and nudging a large language model to produce something more on point.

'Wobbly Spacetime' May Help Resolve Contradictory Physics Theories (theguardian.com) 90

Scientists have proposed a framework that they say could unify quantum mechanics and Albert Einstein's theory of general relatively. "Quantum theory and Einstein's theory of general relativity are mathematically incompatible with each other, so it's important to understand how this contradiction is resolved," said Prof Jonathan Oppenheim, a physicist at University College London, who is behind the theory. The Guardian reports: Until now, the prevailing assumption has been that Einstein's theory of gravity must be modified, or "quantized," in order to fit within quantum theory. This is the approach of string theory, which advances the view that spacetime comprises 10, 11 or possibly 26 dimensions. Another leading candidate, advanced by Rovelli and others, is loop quantum gravity, in which spacetime is composed of finite loops woven into an extremely fine fabric. Oppenheim's theory, published in the journal Physical Review X, challenges the consensus by suggesting that spacetime may be classical and not governed by quantum theory at all. This means spacetime, however closely you zoomed in on it, would be smooth and continuous rather than "quantized" into discrete units. However, Oppenheim introduces the idea that spacetime is also inherently wobbly, subject to random fluctuations that create an intrinsic breakdown in predictability.

"The rate at which time flows is changing randomly and fluctuating in time," said Oppenheim, although he clarifies that time would never actually go into reverse. "It's quite mathematical," he added. "Picturing it in your head is quite difficult." This proposed "wobbliness" would result in a breakdown of predictability, which, Oppenheim says, "many physicists don't like." [...]

Ultimately, whether the theory is correct is not an aesthetic preference, but a question of whether it is a faithful representation of reality. A second paper, published simultaneously in Nature Communications and led by Dr Zach Weller-Davies, formerly of UCL and now at Canada's Perimeter Institute, proposes an experiment designed to uncover "wobbles" in spacetime through tiny fluctuations in the weight of an object. For example, the International Bureau of Weights and Measures in France routinely weigh a 1kg mass, which used to be the 1kg standard. If the fluctuations in measurements of this 1kg mass are smaller than a certain threshold, the theory can be ruled out. "We have shown that if spacetime doesn't have a quantum nature, then there must be random fluctuations in the curvature of spacetime which have a particular signature that can be verified experimentally," said Weller-Davies.

US Students' Math Scores Plunge In Global Education Assessment (axios.com) 131

Ivana Saric reports via Axios: U.S. students lag behind their peers in many industrialized countries when it comes to math, according to the results of a global exam released Tuesday. U.S. students saw a 13-point drop in their 2022 Program for International Student Assessment (PISA) math results when compared to the 2018 exam. The 2022 math score was not only lower than it was in 2012 but it was "among the lowest ever measured by PISA in mathematics" for the U.S., per the Organisation for Economic Co-operation and Development (OECD) country note. The 2018 PISA assessment found that U.S. students straggled behind their peers in East Asia and Europe, per the Washington Post.

PISA examines the proficiency of 15-year-olds in reading, mathematics, and science worldwide. The 2022 PISA edition is the first to take place since the pandemic and compares the test results of nearly 700,000 students across 81 OECD member states and partner economies. The exam, coordinated by the OECD, was first administered in 2000 and is conducted every three years. Due to the COVID-19 pandemic, the 2021 test was delayed until 2022.
What about the rest of the world? According to Axios, a total of 31 countries and economies "maintained or improved upon their 2018 math scores, including Switzerland and Japan."

"10 countries and economies -- Canada, Denmark, Finland, Hong Kong, Ireland, Japan, Korea, Latvia, Macao and the U.K. -- saw their students score proficiently in all three domains and had 'high levels of socio-economic fairness,'" the report adds.

Canadian Government Reaches Deal With Google On Online News Act (www.cbc.ca) 50

An anonymous reader quotes a report from the CBC: Google and the federal government have reached an agreement in their dispute over the Online News Act that would see Google continue to share Canadian news online in return for the company making annual payments to news companies in the range of $100 million. Sources told Radio-Canada and CBC News earlier Wednesday that an agreement had been reached. Heritage Minister Pascale St-Onge confirmed the news Wednesday afternoon. "Many doubted that we would be successful, but I was confident we would find a way to address Google's concerns," she told reporters outside the House of Commons.

The federal government and Google agreed on the regulatory framework earlier this week, a government source familiar with the talks told Radio-Canada. The federal government had estimated earlier this year that Google's compensation should amount to about $172 million. Google estimated the value at $100 million. The company said it would not have a mandatory negotiation model imposed on it for talks with Canadian media organizations, preferring to deal with a single point of contact. The new regulations will allow Google to negotiate with a single group that would represent all media, allowing the company to limit its arbitration risk. Google would still be required to negotiate with the media and sign an agreement. The digital giant could also add additional service contributions, which have yet to be specified.

Files Suggest Climate Summit's Leader Is Using Event To Promote Fossil Fuels (nytimes.com) 139

An anonymous reader quotes a report from the New York Times: As the host of global climate talks that begin this week, the United Arab Emirates is expected to play a central role in forging an agreement to move the world more rapidly away from coal, oil and gas. But behind the scenes, the Emirates has sought to use its position as host to pursue a contradictory goal: to lobby on oil and gas deals around the world, according to an internal document made public by a whistle-blower. In one example, the document offers guidance for Emirati climate officials to use meetings with Brazil's environment minister to enlist her help with a local petrochemical deal by the Abu Dhabi National Oil Company, the Emirates' state-run oil and gas company, known as Adnoc. Emirati officials should also inform their Chinese counterparts that Adnoc was "willing to jointly evaluate international LNG opportunities" in Mozambique, Canada and Australia, the document indicates. LNG stands for liquefied natural gas, which is a fossil fuel and a driver of global warming.

These and other details in the nearly 50-page document -- obtained by the Centre for Climate Reportingand the BBC -- have cast a pall over the climate summit, which begins on Thursday. They are indications, experts said, that the U.A.E. is blurring the boundary between its powerful standing as host of the United Nations climate conference, and U.A.E.'s position as one of the world's largest oil and gas exporters. [...] In private, delegates preparing to travel to Dubai expressed concerns that the cloud surrounding the host nation threatened to discredit the talks themselves. The allegations, they said, risked undermining what many have hoped the negotiations will yield: a deal to replace polluting fossil fuels with clean energy such as wind and solar power. But many said they were reluctant to speak out publicly, for fear of jeopardizing their ability to negotiate.

Aftershocks Can Occur Centuries After Original Earthquake, Says Study (theguardian.com) 37

Large earthquakes are always followed by aftershocks -- a series of smaller but still potentially damaging quakes produced as the ground readjusts. But how long does it take for the aftershocks to die out? A new study suggests some areas can experience aftershocks decades or even centuries after the original earthquake. From a report: In earthquake-prone areas it is hard to tell the difference between aftershocks and ordinary background seismicity. But recognising aftershocks is an important part of assessing a region's disaster risk. To understand how long aftershocks can persist, researchers turned to the stable continental interior of North America, where earthquakes are uncommon. Using statistical analysis they assessed the timing and clustering of quakes that followed three large magnitude 6.5 to 8 historical earthquakes: one near south-east Quebec in Canada in 1663; a trio of quakes around the Missouri-Kentucky border from 1811 to 1812; and an earthquake in Charleston in South Carolina in 1886. Their results, published in Journal of Geophysical Research: Solid Earth, suggest that the Quebec quake in 1663 has likely shaken itself out, but to their surprise nearly a third of modern quakes in the Missouri-Kentucky area were most likely to be aftershocks from the 1811-12 event, and about 16% of recent quakes in the Charleston region are probably aftershocks from the 1886 quake.

Third-Party Data Breach Affecting Canadian Government Could Involve Data From 1999 (theregister.com) 4

Connor Jones reports via The Register: The government of Canada has confirmed its data was accessed after two of its third-party service providers were attacked. The third parties both provided relocation services for public sector workers and the government is currently analyzing a "significant volume of data" which could date back to 1999. No formal conclusions have yet been made about the number of workers impacted due to the large-scale task of analyzing the relevant data. However, the servers impacted by the breach held data related to current and former Canadian government staff, members of the Canadian armed forces, and Royal Canadian Mounted Police workers -- aka Mounties.

"At this time, given the significant volume of data being assessed, we cannot yet identify specific individuals impacted; however, preliminary information indicates that breached information could belong to anyone who has used relocation services as early as 1999 and may include any personal and financial information that employees provided to the companies," a government statement read. Those who think they may be affected are advised to update any login details that may be similar to those used to access BGRS or Sirva's systems. Enabling MFA across all accounts that are used for online transactions is also advised, as is the manual monitoring of personal accounts for any potential malicious activity. Work is currently being carried out to identify and address any vulnerabilities that may have led to the incident, according to the statement.

Why Bill Gates Remains Hopeful about Innovative New Climate Solutions (gatesnotes.com) 64

Bill Gates argues that when it comes to climate change, "there are more reasons to be hopeful than many people realize — and it's not just that renewable energy sources like wind and solar are getting cheaper.

"And it's not just because many of the steps already taken to reduce carbon emissions are working: Carbon emissions from fossil fuels will probably peak in 2025." The main thing that makes me optimistic is all the innovation I'm seeing. As someone who has been funding climate solutions for years, I get to learn from ingenious scientists who are working on ideas that will help the world solve climate change. And their work makes me confident that innovation will help the world get on track to meet its climate goals.

Some people are skeptical when a technology person like me says innovation is the answer. And it's true that new tools aren't the only thing we need. But we won't solve the climate problem without them.

There are two reasons for this. First, we need to eliminate emissions from every sector of the economy. Although some behavior change will help, the world can't achieve its zero-emissions goals without inventing new ways of doing things. For example, the production of concrete and steel alone accounts for around 10 percent of the world's annual greenhouse gases, but right now, we don't have practical ways to make either one without releasing carbon dioxide.

The second reason is that, in a world with limited resources, innovations allow us to magnify the impact of our efforts... We couldn't solve the climate problem with existing technology even if we had unlimited resources — and, of course, we don't have unlimited resources. So we need to be as rigorous as possible about doing the most good with the funding that is available. In my view, that boils down to inventing and deploying new ways to cut emissions and to help people survive and thrive in a warming world.

Gates believes we're at "the beginning of a Clean Industrial Revolution" --pointing readers to Breakthrough Energy's recent State of the Transition Report for more details.

But Gates also provides some specific examples of optimism-fuleing breakthroughs"
  • "To reduce emissions, we need to replace the synthetic fertilizers that release nitrous oxide, a greenhouse gas, when broken down by microbes in the soil; Pivot Bio has genetically modified microbes to provide plants with the nitrogen they need without the excess greenhouse gases that synthetic alternatives produce."
  • "Cement and steel are two of the biggest sources of emissions in this category. Boston Metal is well on the way to making steel with electricity (which can be generated without emissions) instead of coal. CarbonCure and Ecocem have developed low-carbon processes for making cement, and Brimstone has a way to do it while actually removing carbon from the air."
  • "Because of inefficient windows and gaps in what's known as the building envelope, as much as 40% of heated or cooled air leaks out of the typical building. If we can drive that number down, buildings will require less heating and cooling — which will substantially lower our emissions. Aeroseal has developed a polymer that can seal ducts and other crevices; more than a quarter of a million buildings in the U.S. and Canada are already using their product. Another company, Luxwall, has developed a window that's many times more efficient than the single-pane windows used in most buildings. And unlike double-paned windows, it's thin enough to replace single-paned glass without having to rebuild the frame."
