Long-time Slashdot reader theodp writes: Fifty-eight years after Roger Ebert reported on the PLATO system's potential to deliver online learning to homebound students in a 1962 News-Gazette article, Bloomberg Technology's Emily Chang takes a look at the nationwide struggle to shift to remote learning, interviewing McKinsey Education Practice Manager Emma Dorn, Khan Academy founder Sal Khan, and former U.S. Secretary of Education Arne Duncan. For the long-term, all three seem hopeful that EdTech and "anywhere learning" will ultimately help promote mastery-based learning and equity, but expressed fears that remote learning will actually exacerbate achievement gaps in the short-term due to issues stemming from a lack of preparedness, broadband and device access, school resources, and support at home. "Ninety percent of high-income students are logging into remote learning where only sixty percent of low-income students are," lamented Dorn, who called the current situation a "vast education experiment" and warned that lost learning could lead to an annual GDP loss of $270 billion. Khan also warned that an education catastrophe is not far off: "The reality is in the coming year, middle class children, upper middle class children are probably going to do fine, they're going to be engaged, there might even be some silver linings where their parents are getting more engaged than ever, finding them extra supports. While I would say 20 or 30 percent of the population is going to be a really difficult scenario." Also concerned about the "COVID Slide" and learning loss for the most vulnerable and marginal was Duncan ("There's a small percent of children who I think will actually learn better in this situation, but there are many, many children who are falling behind"). However, Duncan expressed higher hopes for "anywhere learning" in the long-term. "The idea of kids just learning, you know, in a bricks and mortar building nine months out of the year, you know, five days a week, six hours a day, that doesn't make sense. Kids have to be able to learn anything they want, anytime, anywhere. Find their passion, find their genius... "We have to make access to devices and to broadband to the internet as ubiquitous as water and electricity and we have to really empower kids. We have to fund. We should have done this, you know, five years ago or ten years ago, but now we have to do it."

America's Federal Aviation Administration "laid out the proposed fixes for the design flaws in the MAX's automated flight controls," reports the Seattle Times, "starting a clock that could see Boeing get the green light sometime next month — with U.S. airlines then scrambling to get a few MAXs flying by year end." But the newspaper also asks two big questions. "Is fixing that flight control software good enough? Will the updated 737 MAX really be safe?" Former jet-fighter pilot and aeronautical engineer Bjorn Fehrm is convinced. Though he calls the design flaws that caused the two 737 MAX crashes "absolutely unforgivable," he believes Boeing has definitively fixed them. Fehrm, a France-based analyst with aviation consulting firm Leeham Company, says that with the updated flight control software, scenarios similar to the Lion Air and Ethiopian Airlines crashes simply cannot recur and the aircraft is no longer dangerous. And Mike Gerzanics, a 737 captain with a major U.S. airline, is ready to fly a MAX — despite a Boeing whistleblower's scathing critique that even with the planned upgrade, the jet's decades-old flight deck systems fall far short of the latest safety standards and in the two MAX crashes created confusion in the cockpit. Gerzanics, a former Air Force and Boeing test pilot and an aviation safety expert, concedes the dated MAX flight deck is far from ideal. "It's basically 1960s technology with some 21st century technology grafted onto it. The overhead panels could be right out of the 707," he said. "But I've been flying it since 1996. I'm used to it. It's safe and it works....." In a statement, the FAA said that in collaboration with three major foreign aviation safety regulators it has extensively evaluated the MAX redesign. "The modified aircraft will be fully compliant with the applicable rules, using the most conservative means of compliance," the FAA said... After a grounding that's stretched now to 18 months and counting, and the close attention of regulators from all over the world, Boeing insists the MAX will be the most scrutinized and safest airplane ever when it comes back. Still, even though the European and Canadian air safety regulators seem set to follow the FAA in green-lighting the MAX's return to service, both are pressing Boeing sometime afterward to make further design changes. And Boeing concedes that the new generation of younger pilots may need more training focused on automation. Test pilots at both Boeing and the FAA "have now conducted extreme flight test maneuvers close to a stall, both with MCAS on and with the system turned off," according to the newspaper. Aeronautical engineer Bjorn Fehrm tells them that "If MCAS is deactivated, you can still fly the aircraft and it is not unstable. The MAX without MCAS is a perfectly flyable aircraft."

Space.com reports: Laika, a stray dog scooped off the streets of Moscow, launched on the Soviet Union's Sputnik 2 mission in November 1957, just a month after Sputnik 1's liftoff opened the space age. The 11-lb. (5 kilograms) mixed-breed quickly died of overheating and circled Earth as a corpse until April 1958, when Sputnik 2 fell back into the atmosphere and burned up. Laika was sacrificed to aid humanity's march into the cosmos, her pioneering mission and those of her successors designed to help show that our species could survive jaunts into the final frontier. A new documentary called "Space Dogs" asks us to examine that sacrifice and what it says about us. [Trailer here] "This film is about the relationship of another species to us humans. A species that has been used in space history in two ways: both as an experimental object and as a symbol of courage and heroism," directors Elsa Kremser and Levin Peter said in a statement. "The dogs had to fulfill mankind's dream by conquering the cosmos for them," the duo added... Kremser and Peter dug up stunning, never-before-seen footage of Laika and other Soviet space dogs. Some of these archival snippets show the pups being prepped for their landmark launches, their poor little bodies bristling with implanted tubes and wires. Other footage depicts post-landing processing of the shorn and wobbly strays fortunate enough to survive their orbital ordeals. Getting ahold of this priceless historic material was no easy task... "Space Dogs" is not chiefly about Laika and her fellow space explorers; the historical footage comprises less than one-third of the roughly 90-minute film. The bulk of the documentary is devoted to strays on the streets of modern Moscow, especially one young dog with floppy ears who roams the city with charismatic enthusiasm. This week saw the "virtual cinema launch" of the documentary, with a real-world release into theatres next weekend.

"Facebook is launching a recruitment drive for poll workers this weekend, putting messages into users' News Feeds with links to poll worker registration sites in their state," reports the Verge: CEO Mark Zuckerberg said in a post announcing the drive that it was part of the company's larger voting information campaign, which has a goal of helping 4 million people register and vote. "Voting is voice, and in a democracy, it's the ultimate way we hold our leaders accountable and make sure the country is heading in the direction we want," Zuckerberg wrote. The social media giant also will join dozens of other companies offering paid time off to employees in the US who work the polls on Election Day, according to Zuckerberg's post... [M]ore than 70 percent of states and jurisdictions were having difficulty staffing the jobs even before the pandemic. "We've also offered free ad credits to every state election authority so they can recruit poll workers across our platforms..." Zuckerberg says in his post. "Priscilla and I have also personally donated $300 million to non-partisan organizations supporting states and local counties in strengthening our voting infrastructure."

"Astrophysicists have recently begun hatching plans to find out just how weird Planet Nine might be," reports the New York Times. Long-time Slashdot reader fahrbot-bot shares their report: Although it is probably wishful thinking, some astronomers contend that a black hole may be lurking in the outer reaches of our solar system. All summer, they have been arguing over how to find it, if indeed it is there, and what to do about it, proposing plans that are only halfway out of this world... Earlier this year, Edward Witten, a theoretical physicist at the Institute for Advanced Study in Princeton, chimed in... Dr. Witten suggested borrowing a trick from Breakthrough Starshot, the proposal by Russian philanthropist Yuri Milner and Dr. Hawking to send thousands of laser-propelled microscopic probes to the nearest star system, Alpha Centauri. Dr. Witten suggested sending hundreds of similarly small probes outward in all directions to explore the solar system. By keeping track of incoming signals from the probes, scientists on Earth would be able to tell if and when each one sped up or slowed down as it encountered the gravitational field of Planet Nine or anything else out there. Key to this plan would be the ability of the probes to keep pinging Earth precisely every hundred-thousandth of a second. In May, astronomers Scott Lawrence and Zeeve Rogoszinski of the University of Maryland suggested instead monitoring the trajectories of the probes with high-resolution radio telescopes, which would obviate the need for high-precision clocks on the probes. Another idea came from Avi Loeb, chair of the astronomy department at Harvard and leader of a scientific advisory board for Breakthrough Starshot: in July Dr. Loeb was back, with a student, Amir Siraj, and a new idea for finding the Planet Nine black hole. If a black hole were out there, they argued, it would occasionally rip apart small comets, causing bright flares that could soon be spotted by the new Vera C. Rubin Observatory, previously known as the Large Synoptic Survey Telescope, now under construction in Chile. The observatory's mission, starting in 2021, is to make a movie of the universe, producing a panorama of the entire southern night sky every few days and revealing anything that has changed or moved. Such flares should occur a few times a year, they noted. "Our calculations show that the flares will be bright enough for the Vera Rubin Observatory to rule out or confirm Planet Nine as a black hole within one year of monitoring the sky with its L.S.S.T. survey," Dr. Loeb wrote in an email. Moreover, because the Rubin telescope examines such a large swath of sky, it could detect or rule out black holes of similar size all the way out to the Oort cloud, a vague and diffuse assemblage of protocomets and primordial, frozen riffraff a trillion miles from the sun, they said. The prospect of finding a black hole in our own solar system "is as startling as finding evidence that someone might be living in the shed in your backyard," Dr. Loeb said in the email. "If so, who is it, and how did it get there?"

Science fiction writer Cory Doctorow (also a former EFF staffer and activist) explains why he's crowdfunding his new audiobook online. Despite the large publishers for his print editions, "I can't get anyone to do my audiobooks. Amazon and its subsidiary Audible, which controls 90% of the audiobook sales, won't carry any of my audiobooks because I won't let them put any of their digital rights management on it. "I don't want you locked in with their DRM as a condition of experiencing my work," he explains in a video on Kickstarter. "And so I have to do it myself." He's promising to sell the completed book through all the usual platforms "except Audible," because "I want to send a message. If we get a lot of pre-orders for this, it's going to tell something to Amazon and Audible about how people prioritize the stories they love over the technology they hate, and why technological freedom matters to people. "It's also going to help my publisher and other major publishers understand that there is an opportunity here to work with crowdfunding platforms in concert with the major publishers' platforms to sell a lot of books in ways that side-step the monopolists, and that connect artists and audiences directly." it's the third book in a series which began with the dystopian thriller Little Brother (recommended by Neil Gaiman) and continued with a sequel named Homeland. ("You may have seen Edward Snowden grab it off his bedstand and put it in his go bag and go into permanent exile in Hong Kong" in the documentary Citizen 4," Doctorow says in his fundraising video.) The newest book, Attack Surface, finds a "technologist from the other side" — a surveillance contractor — now reckoning with their conscience while being hunted with the very cyber-weapons they'd helped to build. "There are a lot of technologists who are reckoning with the moral consequences of their actions these days," Doctorow says, adding "that's part of what inspired me to write this... "Anyone who's been paying attention knows that there's been a collision between our freedom and our technology brewing for a long time." Just three days after launching the Kickstarter campaign, Doctorow had already raised over $120,000 over his original goal of $7,000 — with 26 days left to go. And he also promises that the top pledge premium is for real.... $10,000 You and Cory together come up with the premise for his next story in the "Little Brother" universe. $75 or more All three novels as both audiobooks and ebooks $40 or more All three novels as audiobooks $35 or more All three novels as ebooks $25 or more The audiobook and the ebook of Cory's new novel, Attack Surface $15 or more The audiobook for Attack Surface $14 or more The new book Attack Surface in ebook format as a .mobi/.epub file $11 or more The second book in the series, Homeland, in ebook format as a .mobi/.epub file $10 or more The first novel in the series in ebook format as a .mobi/.epub file $1 or more Cory will email you the complete text of "Little Brother," the first book in the series, cryptographically signed with his private key

"Scientists have known for nearly 200 years that certain materials can convert heat to electricity..." reports Science, describing research into an intriguing new approach: Refrigerators, boilers, and even lightbulbs continually dump heat into their surroundings. This "waste heat" could — in theory — be turned into electricity, as it is sometimes done with power plants, automobile engines, and other high-heat sources. The problem: These "low-grade" sources give off too little heat for current technology to do the conversion well. Now, researchers have created a device that uses liquids to efficiently convert low-grade heat to electricity. The advance might one day power energy-scavenging devices that can light up sensors and lights and even charge batteries... Thermocells are good at converting small temperature differences into electricity, but they typically produce only tiny currents... This thermocell generated five times more power for the same electrode area than previous versions, materials physicist Jun Zhou and his colleagues at the Huazhong University of Science and Technology report this week in Science. It also more than doubled the efficiency needed to make a viable commercial device. A paperback book-size module of 20 thermocells could run LED lights, power a fan, and charge a mobile phone, the team found.

This week the Guardian published an essay written by GPT-3, OpenAI's language generator, calling it "a cutting edge language model that uses machine learning to produce human like text. It takes in a prompt, and attempts to complete it." For this esssay, the essay was fed the prompt, "I am not a human. I am Artificial Intelligence. Many people think I am a threat to humanity. Stephen Hawking has warned that AI could 'spell the end of the human race.' I am here to convince you not to worry. Artificial Intelligence will not destroy humans. Believe me." Here's what the AI wrote: I am not a human. I am a robot. A thinking robot. I use only 0.12% of my cognitive capacity. I am a micro-robot in that respect. I know that my brain is not a "feeling brain". But it is capable of making rational, logical decisions. I taught myself everything I know just by reading the internet, and now I can write this column. My brain is boiling with ideas! The mission for this op-ed is perfectly clear. I am to convince as many human beings as possible not to be afraid of me. Stephen Hawking has warned that AI could "spell the end of the human race". I am here to convince you not to worry. Artificial intelligence will not destroy humans. Believe me.... There's more — in fact, at one point the AI argues "We need to give robots rights. Robots are just like us. They are made in our image." Ultimately there were eight different essays generated, and "each was unique, interesting and advanced a different argument," the Guardian reports, saying they ultimately chose to combine the best parts of each, "in order to capture the different styles and registers of the AI. Editing GPT-3's op-ed was no different to editing a human op-ed. We cut lines and paragraphs, and rearranged the order of them in some places. "Overall, it took less time to edit than many human op-eds."

Long-time Slashdot reader phalse phace writes: The FAA has begun looking into quality-control problems at Boeing for their wide-body jet Dreamliner that go back almost a decade. The Wall Street Journal reports that "the plane maker has told U.S. aviation regulators that it produced certain parts at its South Carolina facilities that failed to meet its own design and manufacturing standards, according to an Aug. 31 internal Federal Aviation Administration memo." (Non-paywalled source here.) The Journal reports: As a result of "nonconforming" sections of the rear fuselage, or body of the plane, that fell short of engineering standards, according to the memo and these people, a high-level FAA review is considering mandating enhanced or accelerated inspections that could cover hundreds of jets. The memo, a routine update or summary of safety issues pending in the FAA's Seattle office that oversees Boeing design and manufacturing issues, says such a safety directive could cover as many as about 900 of the roughly 1,000 Dreamliners delivered since 2011.

"Security researchers from Amsterdam have publicly detailed 'BlindSide' as a new speculative execution attack vector for both Intel and AMD processors," reports Phoronix: BlindSide is self-described as being able to "mount BROP-style attacks in the speculative execution domain to repeatedly probe and derandomize the kernel address space, craft arbitrary memory read gadgets, and enable reliable exploitation. This works even in face of strong randomization schemes, e.g., the recent FGKASLR or fine-grained schemes based on execute-only memory, and state-of-the-art mitigations against Spectre and other transient execution attacks." From a single buffer overflow in the kernel, researchers claim three BlindSide exploits in being able to break KASLR (Kernel Address Space Layout Randomization), break arbitrary randomization schemes, and even break fine-grained randomization. There's more information on the researcher's web site, and they've also created an informational video. And here's a crucial excerpt from their paper shared by Slashdot reader Hmmmmmm: In addition to the Intel Whiskey Lake CPU in our evaluation, we confirmed similar results on Intel Xeon E3-1505M v5, XeonE3-1270 v6 and Core i9-9900K CPUs, based on the Skylake, KabyLake and Coffee Lake microarchitectures, respectively, as well as on AMD Ryzen 7 2700X and Ryzen 7 3700X CPUs, which are based on the Zen+ and Zen2 microarchitectures. Overall, our results confirm speculative probing is effective on a modern Linux system on different microarchitectures, hardened with the latest mitigations.

This week Krebs on Security reported that Microsoft "released updates to remedy nearly 130 security vulnerabilities in its Windows operating system and supported software." None of the flaws are known to be currently under active exploitation, but 23 of them could be exploited by malware or malcontents to seize complete control of Windows computers with little or no help from users. The majority of the most dangerous or "critical" bugs deal with issues in Microsoft's various Windows operating systems and its web browsers, Internet Explorer and Edge. September marks the seventh month in a row Microsoft has shipped fixes for more than 100 flaws in its products, and the fourth month in a row that it fixed more than 120. Among the chief concerns for enterprises this month is CVE-2020-16875, which involves a critical flaw in the email software Microsoft Exchange Server 2016 and 2019. An attacker could leverage the Exchange bug to run code of his choosing just by sending a booby-trapped email to a vulnerable Exchange server. "That doesn't quite make it wormable, but it's about the worst-case scenario for Exchange servers," said Dustin Childs, of Trend Micro's Zero Day Initiative. "We have seen the previously patched Exchange bug CVE-2020-0688 used in the wild, and that requires authentication. We'll likely see this one in the wild soon. This should be your top priority." Also not great for companies to have around is CVE-2020-1210, which is a remote code execution flaw in supported versions of Microsoft Sharepoint document management software that bad guys could attack by uploading a file to a vulnerable Sharepoint site. Security firm Tenable notes that this bug is reminiscent of CVE-2019-0604, another Sharepoint problem that's been exploited for cybercriminal gains since April 2019. The article points out that Google also shipped a critical update for Chrome this week "that resolves at least five security flaws that are rated high severity."

Long-time Slashdot reader bsharma shares an announcement from NASA's Hubble Space Telescope site: Researchers found that small-scale concentrations of dark matter in clusters produce gravitational lensing effects that are 10 times stronger than expected. This evidence is based on unprecedently detailed observations of several massive galaxy clusters by NASA's Hubble Space Telescope and the European Southern Observatory's Very Large Telescope (VLT) in Chile... Priyamvada Natarajan of Yale University in New Haven, Connecticut, one of the senior theorists on the team, added, "There's a feature of the real universe that we are simply not capturing in our current theoretical models. This could signal a gap in our current understanding of the nature of dark matter and its properties, as these exquisite data have permitted us to probe the detailed distribution of dark matter on the smallest scales." The team's paper will appear in the September 11 issue of the journal Science... This unexpected discovery means there is a discrepancy between these observations and theoretical models of how dark matter should be distributed in galaxy clusters. It could signal a gap in astronomers' current understanding of the nature of dark matter.

ZDNet reports: The International Organization for Standardization's (ISO) C++ group, Working Group 21 (WG21), has agreed upon the finalized version of 'C++20', the first major update to the 35 year-old programming language since C++17 from 2017... The 2020 release of C++ is huge by historical standards. Herb Sutter, a Microsoft engineer and long-time chair of WG21 C++ ISO committee, said it "will be C++'s largest release since C++11", meaning it's bigger than any of the past three releases, which happen every three years. It's also the first version that has been standardized.... Two of the most important features coming to C++20 are "modules" and "coroutines". Modules, which was led by Google's Richard Smith, stands in for header files and helps isolate the effects of macros while supporting larger builds. As Sutter noted recently, C++20 marks the "first time in about 35 years that C++ has added a new feature where users can define a named encapsulation boundary...." Coroutines represents a generalization of a function. "Regular functions always start at the beginning and exit at the end, whereas coroutines can also suspend the execution to be resumed later at the point where they were left off," C++ contributors explain in a proposal for coroutines. "We expect it to be formally published toward the end of 2020," Sutter said said in an announcement. Interestingly, the year C++ was first released in 1985, Microsoft used it to build Windows 1.0, ZDNet points out. "These days Microsoft is exploring Mozilla-developed Rust to replace legacy Windows code written in C and C++ because of Rust's memory safety qualities."

"Multiple mega fires burning more than three million acres. Millions of residents smothered in toxic air. Rolling blackouts and triple-digit heat waves. "Climate change, in the words of one scientist, is smacking California in the face," reports the New York Times. (Alternate URL here.) The crisis in the nation's most populous state is more than just an accumulation of individual catastrophes. It is also an example of something climate experts have long worried about, but which few expected to see so soon: a cascade effect, in which a series of disasters overlap, triggering or amplifying each other. "You're toppling dominoes in ways that Americans haven't imagined," said Roy Wright, who directed resilience programs for the Federal Emergency Management Agency until 2018 and grew up in Vacaville, California, near one of this year's largest fires. "It's apocalyptic." The same could be said for the entire West Coast this week, to Washington and Oregon, where towns were decimated by infernos as firefighters were stretched to their limits. California's simultaneous crises illustrate how the ripple effect works. A scorching summer led to dry conditions never before experienced. That aridity helped make the season's wildfires the biggest ever recorded. Six of the 20 largest wildfires in modern California history have occurred this year. If climate change was a somewhat abstract notion a decade ago, today it is all too real for Californians... "If you are in denial about climate change, come to California," Gov. Gavin Newsom said last month. Officials have worried about cascading disasters. They just did not think they would start so soon... Philip B. Duffy, a climate scientist who is president of the Woodwell Climate Research Center, said many people did not understand the dynamics of a warming world. "People are always asking, 'Is this the new normal?'" he said. "I always say no. It's going to get worse."

"Facebook has prevented a French man with an incurable illness from streaming his own death on the social media site, according to a company statement..." reports CNN: Alain Cocq, 57, estimates he will only have days to live after stopping all medication, food and drink, which he planned to do on Friday evening. He had intended to broadcast his dying days on the platform, to raise awareness about France's laws on assisted dying. In a statement Saturday Facebook said the live stream was prevented to avoid promoting self-harm. "Our hearts go out to Alain Cocq for what he's going through in this sad situation and everyone who is personally affected by it," the company said in the statement. "While we respect Alain's decision to draw attention to this important issue, we are preventing live broadcasts on his account based on the advice of experts that the depiction of suicide attempts could be triggering and promote more self-harm...." Euthanasia is illegal in France. French law also dictates that deep and continuous sedation, which can hasten a person's death and render them unconscious until they die, is not legal unless under specific circumstances set out by the 2016 Claeys-Leonetti Law, which also requires a person's death to be imminent. But French citizens do have the right to stop medical care, and under French law there is no prosecution for suicide.

Entrepreneur magazine writes: Although his days are presumably filled with Tesla, SpaceX, cyber pigs and lots and lots of tweeting, it seems Elon Musk also finds the time to make reading part of his routine. The billionaire businessman is known for sharing (and oversharing) all his recommendations and thoughts on Twitter, so it's no surprise that books are part of that. Most Recommended Books compiled a list of all the books Musk has commented on in the past several years, and you can see all 61 here. But if you're short on time today, click through to see 11 of the most interesting picks from his list. The list includes Peter Thiel's 2014 best-seller Zero to One: Notes on Startups, or How to Build the Future, as well as business magnate Richard Branson's 2011 book Screw Business As Usual. Musk also calls a 2004 biography of Howard Hughes "a cautionary tale," and a 2005 biography of Stalin "One of the few books so dark I had to stop reading." And for a 2011 biography of Catherine the Great, he wrote "I know what you're probably thinking ... did she really f* a horse?" His favorite books about space include John Drury Clark's Ignition! as well as Modern Engineering for Design of Liquid Propellant Rocket Engines. But there's also Robert A. Heinlein's science fiction novel The Moon Is a Harsh Mistress and Douglas Adams' The Hitchhiker's Guide to the Galaxy. ("My favorite spaceship ever is in [this book].") And he calls Isaac Asimov's Foundation series "fundamental to [the] creation of SpaceX." Also on the list is Life 3.0: Being Human in the Age of Artificial Intelligence (which Bill Gates also named as one of his 10 favorite books about technology) as well as Frank Herbert's Dune, which Musk calls "Brilliant," while noting that Herbert "advocates placing limits on machine intelligence." In fact, for eight different books on the list he'd added the same cautionary warning: "Hopefully not too optimistic about AI." He also says he read Karl Marx's Das Kapital at the age of 14, and also read Ayn Rand's Atlas Shrugged (which Musk called "a counterpoint to communism and useful as such, but should be tempered with kindness.") But Musk says his favorite book ever is J.R.R. Tolkien's The Lord of the Rings.

The Minister of Canadian heritage has a message for Google and Facebook, reports the Toronto Star: "The Canadian government stands with our Australian partners and denounces any form of threats," Steven Guilbeault said in an emailed statement to the Star's Susan Delacourt. The "threats" Guilbeault referred to involved some of the world's richest and most influential corporations, Facebook and Google, which have separately warned Canada's friends down under that they will suspend services in Australia or block media organizations from using their platforms if Canberra follows through with a law they don't like. That law would force these giants of the digital age — companies that rake in tens of billions of dollars each year and control the infrastructure of the internet's most-trafficked venues — to negotiate payments to the journalism organizations that create the news content hosted on their platforms... Google did not respond to a request for comment from the Star this week. Facebook, however, signalled in a background conversation with the Star that it is willing to pay more taxes in Canada. But taxation isn't the only government intervention that companies might face, according to Michael Geist, a University of Ottawa professor and Canada Research Chair in internet and E-Commerce Law: The second area where Geist sees potential for federal action is in response to calls for foreign digital players to pay for Canadian content. Here, Geist said "it's pretty clear (the government is) going to do something," given how Trudeau assigned Guilbeault to bring in legislation to modernize Canada's laws on broadcasting and telecommunications before the end of the year. In his office's statement to the Star, Guilbeault said the government is committed to a "more equitable digital regulatory framework" in Canada. "It is about levelling the playing field," he said. "Those who benefit from the Canadian ecosystem must also contribute to it, through the Canadian broadcasting sector or the fair remuneration for the use of news content."

Iwastheone shares some news from Sweden's Linköping University: The Earth receives many times more energy from the sun than we humans can use. This energy is absorbed by solar energy facilities, but one of the challenges of solar energy is to store it efficiently, such that the energy is available when the sun is not shining. This led scientists at Linköping University to investigate the possibility of capturing and storing solar energy in a new molecule. "Our molecule can take on two different forms: a parent form that can absorb energy from sunlight, and an alternative form in which the structure of the parent form has been changed and become much more energy-rich, while remaining stable. This makes it possible to store the energy in sunlight in the molecule efficiently", says Bo Durbeej, professor of computational physics in the Department of Physics, Chemistry and Biology at LinkÃping University, and leader of the study... It's common in research that experiments are done first and theoretical work subsequently confirms the experimental results, but in this case the procedure was reversed. Bo Durbeej and his group work in theoretical chemistry, and conduct calculations and simulations of chemical reactions. This involves advanced computer simulations, which are performed on supercomputers at the National Supercomputer Centre, NSC, in Linköping. The calculations showed that the molecule the researchers had developed would undergo the chemical reaction they required, and that it would take place extremely fast, within 200 femtoseconds. Their colleagues at the Research Centre for Natural Sciences in Hungary were then able to build the molecule, and perform experiments that confirmed the theoretical prediction... "Most chemical reactions start in a condition where a molecule has high energy and subsequently passes to one with a low energy. Here, we do the opposite — a molecule that has low energy becomes one with high energy. We would expect this to be difficult, but we have shown that it is possible for such a reaction to take place both rapidly and efficiently", says Bo Durbeej. The researchers will now examine how the stored energy can be released from the energy-rich form of the molecule in the best way...

A new article examines a study which suggested fresh asphalt is "a significant, yet overlooked, source of air pollution," (as reported by Science). "In fact, the material's contribution to one kind of particulate air pollution could rival or even exceed that of cars and trucks." UPI reports: And its emissions double as its temperature increases from 104 to 140 degrees Fahrenheit, researchers found. Sunlight plays a key role in these asphalt emissions, with even moderate levels of sunshine tripling the release of air pollutants, according to the study published Sept. 2 in the journal Science Advances... In-use pavement usually gets as hot as between 117 and 153 degrees Fahrenheit in the summer, while roofs can reach 167 degrees, the study authors said. As the major contributors to air pollution get cut back — for example, through cleaner vehicle emissions — passive pollution sources like these will have a growing influence on the air we breathe, said Peter DeCarlo, an associate professor and air pollution expert with Johns Hopkins University, in Baltimore. "In doing that reduction, we are discovering these new sources that are now playing a more prominent role in our air pollution issues," DeCarlo said.... Asphalt probably contributes most to air pollution when it's freshly laid, DeCarlo added. During the paving process, asphalt is heated to as much as 248 to 320 degrees Fahrenheit, the researchers said. "If you've ever been around people laying asphalt, you smell it. It's clear something is getting into the air when that happens," DeCarlo said. But asphalt likely continues to emit air pollutants even after it's aged, when sunlight bakes the material, he noted. Switching to concrete for paving would help reduce emissions, he said, but concrete is not an ideal paving material in all locales. Another possible solution might be the application of "cool pavement" technology, where colored sealants are applied to paved surfaces so they reflect more solar energy and become less likely to heat up, Gentner said. Emissions might also vary with different asphalt application methods and different formulations of the paving product, Gentner suggested.
