"Predating even Toy Story, ReBoot was the first 3D animated television show," writes longtime Slashdot reader sandbagger, sharing a new report from Global News. "The master tapes have been located in storage but the hardware needed to play the 1990s-era media has yet to be located." From the report: Produced in Vancouver by Mainframe Entertainment, it aired on YTV between 1994 and 2001, and decades later still has a committed fan base. Among those super fans are Jacob Weldon and Raquel Lin, a B.C. duo now crafting a documentary about the creation of the show and its impact in the film and TV world. Weldon said he wants to see ReBoot recognized for its place in the evolution of computer animation -- recognition he said it rarely gets.

When ReBoot was finally cancelled -- cut short in its fourth and final season -- its protagonists were left in peril and the show ended on a cliffhanger. It's another factor that Lin and Weldon say has helped immortalize the show and has helped fans hoping for a revival that might finally explain the characters' fate. Earlier this month, the documentary also got a potential major boost. Mainframe allowed Lin and Weldon to come to the studio to look for the show's original master tapes, recordings some believed might have been permanently lost. They struck gold. "They had boxes upon boxes upon boxes, hundreds of tapes," Lin said. "It's original resolution, original frame rate, uncompressed. If we could get a deck to play these, they would look beautiful," Weldon said.

Finding that deck, however, is the pair's next major challenge. The recordings are on a rare digital tape format called D1, a technology that Weldon said was cutting edge and rare when Mainframe was using it. It's even harder to find today, and even Mainframe doesn't have the equipment to play the tapes back. Weldon and Lin have since put out a call on social media for a working Bosch BTS D1 deck that would allow them to play the tapes, and incorporate them into their documentary. "I can't tell you how many people have called us, DM'd us, emailed us -- people from all over the world," Lin said. While the pair still haven't secured the deck, they're aiming to release their documentary by next summer. They're hoping it will help renew interest in the show, introduce it to new generations and perhaps see it get new life on a streaming platform.

Melbourne-based developer xssfox has championed a unique "diagonal mode" for monitors by utilizing Linux's xrandr (x resize and rotate) tool, finding a 22-degree tilt to the left to be the ideal angle for software development on her 32:9 aspect ratio monitor. As Tom's Hardware notes, Linux is the "only OS to support a diagonal monitor mode, which you can customize to any tilt of your liking." It begs the question, could 2024 be the year of the Linux diagonal desktop? From the report: Xssfox devised a consistent method to appraise various screen rotations, working through the staid old landscape and portrait modes, before deploying xrandr to test rotations like the slightly skewed 1 degree and an indecisive 45 degrees. These produced mixed results of questionable benefits, so the search for the Goldilocks solution continued. It turns out that a 22-degree tilt to the left was the sweet spot for xssfox. This rotation delivered the best working screen space on what looks like a 32:9 aspect ratio monitor from Dell. "So this here, I think, is the best monitor orientation for software development," the developer commented. "It provides the longest line lengths and no longer need to worry about that pesky 80-column limit."

If you have a monitor with the same aspect ratio, the 22-degree angle might work well for you, too. However, people with other non-conventional monitor rotation needs can use xssfox's javascript calculator to generate the xrandr command for given inputs. People who own the almost perfectly square LG DualUp 28MQ780 might be tempted to try 'diamond mode,' for example. We note that Windows users with AMD and Nvidia drivers are currently shackled to applying screen rotations using 90-degree steps. MacOS users apparently face the same restrictions.

An anonymous reader quotes a report from The Register: Bruce Perens, one of the founders of the Open Source movement, is ready for what comes next: the Post-Open Source movement. "I've written papers about it, and I've tried to put together a prototype license," Perens explains in an interview with The Register. "Obviously, I need help from a lawyer. And then the next step is to go for grant money." Perens says there are several pressing problems that the open source community needs to address. "First of all, our licenses aren't working anymore," he said. "We've had enough time that businesses have found all of the loopholes and thus we need to do something new. The GPL is not acting the way the GPL should have done when one-third of all paid-for Linux systems are sold with a GPL circumvention. That's RHEL." RHEL stands for Red Hat Enterprise Linux, which in June, under IBM's ownership, stopped making its source code available as required under the GPL. Perens recently returned from a trip to China, where he was the keynote speaker at the Bench 2023 conference. In anticipation of his conversation with El Reg, he wrote up some thoughts on his visit and on the state of the open source software community. One of the matters that came to mind was Red Hat.

"They aren't really Red Hat any longer, they're IBM," Perens writes in the note he shared with The Register. "And of course they stopped distributing CentOS, and for a long time they've done something that I feel violates the GPL, and my defamation case was about another company doing the exact same thing: They tell you that if you are a RHEL customer, you can't disclose the GPL source for security patches that RHEL makes, because they won't allow you to be a customer any longer. IBM employees assert that they are still feeding patches to the upstream open source project, but of course they aren't required to do so. This has gone on for a long time, and only the fact that Red Hat made a public distribution of CentOS (essentially an unbranded version of RHEL) made it tolerable. Now IBM isn't doing that any longer. So I feel that IBM has gotten everything it wants from the open source developer community now, and we've received something of a middle finger from them. Obviously CentOS was important to companies as well, and they are running for the wings in adopting Rocky Linux. I could wish they went to a Debian derivative, but OK. But we have a number of straws on the Open Source camel's back. Will one break it?"

Another straw burdening the Open Source camel, Perens writes, "is that Open Source has completely failed to serve the common person. For the most part, if they use us at all they do so through a proprietary software company's systems, like Apple iOS or Google Android, both of which use Open Source for infrastructure but the apps are mostly proprietary. The common person doesn't know about Open Source, they don't know about the freedoms we promote which are increasingly in their interest. Indeed, Open Source is used today to surveil and even oppress them." Free Software, Perens explains, is now 50 years old and the first announcement of Open Source occurred 30 years ago. "Isn't it time for us to take a look at what we've been doing, and see if we can do better? Well, yes, but we need to preserve Open Source at the same time. Open Source will continue to exist and provide the same rules and paradigm, and the thing that comes after Open Source should be called something else and should never try to pass itself off as Open Source. So far, I call it Post-Open." Post-Open, as he describes it, is a bit more involved than Open Source. It would define the corporate relationship with developers to ensure companies paid a fair amount for the benefits they receive. It would remain free for individuals and non-profit, and would entail just one license. He imagines a simple yearly compliance process that gets companies all the rights they need to use Post-Open software. And they'd fund developers who would be encouraged to write software that's usable by the common person, as opposed to technical experts.

Pointing to popular applications from Apple, Google, and Microsoft, Perens says: "A lot of the software is oriented toward the customer being the product -- they're certainly surveilled a great deal, and in some cases are actually abused. So it's a good time for open source to actually do stuff for normal people." The reason that doesn't often happen today, says Perens, is that open source developers tend to write code for themselves and those who are similarly adept with technology. The way to avoid that, he argues, is to pay developers, so they have support to take the time to make user-friendly applications. Companies, he suggests, would foot the bill, which could be apportioned to contributing developers using the sort of software that instruments GitHub and shows who contributes what to which products. Merico, he says, is a company that provides such software. Perens acknowledges that a lot of stumbling blocks need to be overcome, like finding an acceptable entity to handle the measurements and distribution of funds. What's more, the financial arrangements have to appeal to enough developers. "And all of this has to be transparent and adjustable enough that it doesn't fork 100 different ways," he muses. "So, you know, that's one of my big questions. Can this really happen?" Perens believes that the General Public License (GPL) is insufficient for today's needs and advocates for enforceable contract terms. He also criticizes non-Open Source licenses, particularly the Commons Clause, for misrepresenting and abusing the open-source brand.

As for AI, Perens views it as inherently plagiaristic and raises ethical concerns about compensating original content creators. He also weighs in on U.S.-China relations, calling for a more civil and cooperative approach to sharing technology.

More than two decades after J.K. Rowling introduced the world to a universe of magical creatures, forbidden forests and a teenage wizard, Harry Potter is finding renewed relevance in a very different body of literature: AI research. From a report: A growing number of researchers are using the best-selling Harry Potter books to experiment with generative artificial intelligence technology, citing the series' enduring influence in popular culture and the wide range of language data and complex wordplay within its pages. Reviewing a list of studies and academic papers referencing Harry Potter offers a snapshot into cutting-edge AI research -- and some of the thorniest questions facing the technology.

In perhaps the most notable recent example, Harry, Hermione and Ron star in a paper titled "Who's Harry Potter?" that sheds light on a new technique helping large language models to selectively forget information. It's a high-stakes task for the industry: Large language models, which power AI chatbots, are built on vast amounts of online data, including copyrighted material and other problematic content. That has led to lawsuits and public scrutiny for some AI companies. The paper's authors, Microsoft researchers Mark Russinovich and Ronen Eldan, said they've demonstrated that AI models can be altered or edited to remove any knowledge of the existence of the Harry Potter books, including characters and plots, without sacrificing the AI system's overall decision-making and analytical abilities.

The duo said they chose the books because of their universal familiarity. "We believed that it would be easier for people in the research community to evaluate the model resulting from our technique and confirm for themselves that the content has indeed been 'unlearned,'" said Russinovich, chief technology officer of Microsoft Azure. "Almost anyone can come up with prompts for the model that would probe whether or not it 'knows' the books. Even people who haven't read the books would be aware of plot elements and characters."

Abstract of a paper published on the American Psychological Association: People are frequently invited to join others for fun social activities. They may be invited to lunch, to attend a sporting event, to watch the season finale of a television show, and so forth. Invitees -- those who are on the receiving ends of invitations -- sometimes accept invitations from inviters -- those who extend invitations -- but other times, invitees decline. Unfortunately, saying no can be hard, leading invitees to accept invitations when they would rather not. The present work sheds light on one factor that makes it so hard to decline invitations.

We demonstrate that invitees overestimate the negative ramifications that arise in the eyes of inviters following an invitation decline. Invitees have exaggerated concerns about how much the decline will anger the inviter, signal that the invitee does not care about the inviter, make the inviter unlikely to offer another invitation in the future, and so forth. We also demonstrate that this asymmetry emerges in part because invitees exaggerate the degree to which inviters focus on the decline itself, as opposed to the thoughts ran through the invitee's head before deciding. Indeed, across multiple studies, we find support for this process through mediation and moderation, while simultaneously finding evidence against multiple alternative accounts. We conclude with a discussion of the contributions and limitations of this research, along with directions for future work.

Beeper Mini, which offers iPhone messaging on Android phones, has grown fast and its duel with Apple has gotten the attention of antitrust regulators. The New York Times: Apple was caught by surprise when Beeper Mini gave Android devices access to its modern, iPhone-only service. Less than a week after Beeper Mini's launch, Apple blocked the app by changing its iMessage system. It said the app created a security and privacy risk. Apple's reaction set off a game of Whac-a-Mole, with Beeper Mini finding alternative ways to operate and Apple finding new ways to block the app in response. The duel has raised questions in Washington about whether Apple has used its market dominance over iMessage to block competition and force consumers to spend more on iPhones than lower-priced alternatives.

The Justice Department has taken interest in the case. Beeper Mini met with the department's antitrust lawyers on Dec. 12, two people familiar with the meeting said. Eric Migicovsky, a co-founder of the app's parent company, Beeper, declined to comment on the meeting, but the department is in the middle of a four-year-old investigation into Apple's anticompetitive behavior. The Federal Trade Commission said in a blog post on Thursday that it would scrutinize "dominant" players that "use privacy and security as a justification to disallow interoperability" between services. The post did not name any companies.

The giants of the consulting world face an unusual quandary this year: many of them are in the process of dismissing hundreds of staffers even after they hired thousands of college graduates to deal with new demand. Now, one of the biggest of them all is looking to AI to change that. From a report: Deloitte is using AI to evaluate existing staffers' skills and map out plans that would shift employees away from quieter parts of the business and into roles that are more in demand. It's part of a broader bet by the professional services firm that the technology will allow it to moderate hiring growth over time.

The moves come after Deloitte added 130,000 staffers this year. But in the midst of those hirings, though, the firm warned thousands of staffers in the US and UK that their jobs were at risk of becoming redundant after the company was forced to restructure certain areas of the business in response to a slowdown in demand. "It is obviously a great objective to be able to avoid large swings of hirings and layoffs," said Stevan Rolls, global chief talent officer at Deloitte. "You could always be more efficient and effective about finding the right people."

Scientists have pinpointed the cause of nausea and vomiting in pregnancy, "finding that the severity of illness is influenced by how much of a hormone called GDF15 the growing fetus makes," reports Science Magazine. The findings have been published in the journal Nature. From the report: GDF15 is present in the blood of nonpregnant people and is known to be associated with nausea; it's also been tested as a weight loss aid because of its tendency to suppress appetite. Levels of the hormone rise sharply in early pregnancy and increase throughout gestation. Pregnant people with higher GDF15 concentrations have been documented as having a higher risk of vomiting and nausea. Some researchers suggest the hormone-caused aversion to some smells and tastes might encourage an expectant parent to avoid foods potentially dangerous to the fetus.

To find out more about GDF15 changes during pregnancy, University of Cambridge physician-scientist Stephen O'Rahilly and colleagues studied half a dozen pregnant people who were known from previous genetic screening to produce a slightly different version of the GDF15 protein from their fetuses. Researchers could take advantage of that difference to trace whether GDF15 in the parent's blood originated in the parental or fetal genome: Almost all of it came from the fetus, O'Rahilly says. The team also took a closer look at the link between GDF15 levels and pregnancy sickness. Consistent with previous research, questionnaires from more than 300 participants showed that people who reported vomiting and nausea had significantly higher levels of circulating GDF15 on average than people without these symptoms. The researchers also found elevated levels of GDF15 in an analysis of more than 50 women hospitalized with hyperemesis gravidarum.

Still, hormone levels alone couldn't explain the difference in sickness severity. "There was a big overlap" in GDF15 levels between the groups, O'Rahilly says. He and co-author Marlena Fejzo, a researcher at the University of Southern California, suspected that people's sensitivity to GDF15 might also play a role. (Fejzo began to study the condition after her own pregnancy loss following hyperemesis gravidarum.) To test the idea, the researchers studied 10 nonpregnant people with a rare genetic variant known to carry a heightened risk of hyperemesis gravidarum. These people had reduced GDF15 levels in their blood, hinting that naturally low levels of the hormone might predispose someone to sickness during pregnancy. The researchers found the opposite when they asked 20 pregnant people with beta thalassemia, a blood disorder associated with high GDF15 levels, about their pregnancy symptoms: Just 5% of this group reported nausea or vomiting. O'Rahilly's lab found a similar pattern in animal experiments.

An anonymous reader quotes a report from MIT Technology Review: In a paper published in Nature today, the researchers say it is the first time a large language model has been used to discover a solution to a long-standing scientific puzzle -- producing verifiable and valuable new information that did not previously exist. "It's not in the training data -- it wasn't even known," says coauthor Pushmeet Kohli, vice president of research at Google DeepMind. Large language models have a reputation for making things up, not for providing new facts. Google DeepMind's new tool, called FunSearch, could change that. It shows that they can indeed make discoveries -- if they are coaxed just so, and if you throw out the majority of what they come up with.

FunSearch (so called because it searches for mathematical functions, not because it's fun) continues a streak of discoveries in fundamental math and computer science that DeepMind has made using AI. First Alpha Tensor found a way to speed up a calculation at the heart of many different kinds of code, beating a 50-year record. Then AlphaDev found ways to make key algorithms used trillions of times a day run faster. Yet those tools did not use large language models. Built on top of DeepMind's game-playing AI AlphaZero, both solved math problems by treating them as if they were puzzles in Go or chess. The trouble is that they are stuck in their lanes, says Bernardino Romera-Paredes, a researcher at the company who worked on both AlphaTensor and FunSearch: "AlphaTensor is great at matrix multiplication, but basically nothing else." FunSearch takes a different tack. It combines a large language model called Codey, a version of Google's PaLM 2 that isfine-tuned on computer code, with other systems that reject incorrect or nonsensical answers and plug good ones back in.

The researchers started by sketching out the problem they wanted to solve in Python, a popular programming language. But they left out the lines in the program that would specify how to solve it. That is where FunSearch comes in. It gets Codey to fill in the blanks -- in effect, to suggest code that will solve the problem. A second algorithm then checks and scores what Codey comes up with. The best suggestions -- even if not yet correct -- are saved and given back to Codey, which tries to complete the program again. After a couple of million suggestions and a few dozen repetitions of the overall process -- which took a few days -- FunSearch was able to come up with code that produced a correct and previously unknown solution to the cap set problem, which involves finding the largest size of a certain type of set. Imagine plotting dots on graph paper. [...] To test its versatility, the researchers used FunSearch to approach another hard problem in math: the bin packing problem, which involves trying to pack items into as few bins as possible. This is important for a range of applications in computer science, from data center management to e-commerce. FunSearch came up with a way to solve it that's faster than human-devised ones.

sciencehabit shares a report from Science Magazine: Grunge music: a source of validation for a generation of disaffected youth. And a surprising source of scientific inspiration for Earl Bellinger of the Max Planck Institute for Astrophysics. While listening to Soundgarden's 1994 hit Black Hole Sun 2 years ago, he contemplated a curious question: Might itty-bitty black holes from the dawn of time be lurking in the hearts of giant stars? A new study by Bellinger and colleagues suggests the idea is not so far-fetched. Astronomers could detect these trapped black holes by the vibrations they cause on the star's surface. And if there's enough of them out there, they could function as the mysterious dark matter that holds the universe together.

The researchers found that the black holes would sink to the star's core where hydrogen atoms undergo fusion to produce heat and light. At first, very little would happen. Even a dense stellar core is mostly empty space. The most microscopic of the black holes would have a hard time finding matter to consume and its growth would be extremely slow, Bellinger says. "It could take longer than the lifetime of the universe to eat the star." But larger ones, roughly as massive as the asteroid Ceres or the dwarf planet Pluto, would get bigger on timescales of only a few hundred million years. Material would spiral onto the black hole, forming a disk that would heat up through friction and emit radiation. Once the black hole was about as massive as Earth, it would produce significant amounts of radiation, shining brightly and churning up the star's core like pot of boiling water. "It will become a black hole -- powered object rather than fusion-powered object," says study co-author Matt Caplan, a theoretical physicist at Illinois State University. He and his colleagues have dubbed these entities "Hawking stars."

The European Space Agency's Gaia satellite has spotted about 500 such anomalously cool giant stars, known as red stragglers, Bellinger says. To figure out whether these might actually be hiding a black hole, he says, astronomers could tune in to the particular frequencies at which the stars vibrate. Because a Hawking star would churn throughout its interior, rather than just in the topmost layers like an ordinary red giant, it would be expected to thrum with a particular combination of frequencies. Such waves can be detected in the way the star's light pulses and throbs. Bellinger is applying for funding to study the known red stragglers and see whether any display the characteristic vibrations of a black hole. The study has been published in The Astrophysical Journal.

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."

More than half a century ago, Digital Equipment Corporation released the first of their 16-bit PDP-11 minicomputers, continuing the PDP-11 line until 1997.

This week long-time Slashdot reader Shayde writes: I've been working on a 1986 PDP/11 that I basically got as a "barn find" from an estate sale a year ago. The project has absolutely had it's ups and downs, as the knowledgebase for these machines is aging quickly. I'm hoping to restore my own expertise with this build, but it's been challenging finding parts, technical details, and just plain information.

I leaned pretty heavily on the folks at the Vintage Computing Federation, as well as connections I've made in the industry — and made some great progress... Check it out if you're keen on retrocomputing and old minicomputers and DEC gear.
The entire saga is chronicled in three videos titled "Barn Find PDP 11/73 — Will it boot" — part 1, part 2, and this week's latest video. "What started as a curiosity has turned into an almost 10-month-long project," it concludes, creeping up hopefully on the possibility of an awe-struck glimpse at the PDP-11's boot sequence (over two minutes long)

"So cool," responded Jeremiah Cornelius (Slashdot reader #137) in a comment on the submitted Slashdot story. "I have huge affection for these beasts. I cut my teeth in High School on a DEC PDP11/70 and AT&T SysV, and a little RSTS/E in 1979-82. We switched systems by loading different cakelid platters into the washing-machine drives, and toggling the magenta keys.

"This fall, a small number of senior leaders approached the board of OpenAI with concerns about chief executive Sam Altman," the Washington Post reported late Friday: Altman — a revered mentor, and avatar of the AI revolution — had been psychologically abusive, the employees alleged, creating pockets of chaos and delays at the artificial-intelligence start-up, according to two people familiar with the board's thinking who spoke on the condition of anonymity to discuss sensitive internal matters. The company leaders, a group that included key figures and people who manage large teams, mentioned Altman's allegedly pitting employees against each other in unhealthy ways, the people said.

Although the board members didn't use the language of abuse to describe Altman's behavior, these complaints echoed some of their interactions with Altman over the years, and they had already been debating the board's ability to hold the CEO accountable. Several board members thought Altman had lied to them, for example, as part of a campaign to remove board member Helen Toner after she published a paper criticizing OpenAI, the people said.

The new complaints triggered a review of Altman's conduct during which the board weighed the devotion Altman had cultivated among factions of the company against the risk that OpenAI could lose key leaders who found interacting with him highly toxic. They also considered reports from several employees who said they feared retaliation from Altman: One told the board that Altman was hostile after the employee shared critical feedback with the CEO and that he undermined the employee on that person's team, the people said...

The complaints about Altman's alleged behavior, which have not previously been reported, were a major factor in the board's abrupt decision to fire Altman on Nov. 17, according to the people. Initially cast as a clash over the safe development of artificial intelligence, Altman's firing was at least partially motivated by the sense that his behavior would make it impossible for the board to oversee the CEO.
Bloomberg reported Friday: The board had heard from some senior executives at OpenAI who had issues with Altman, said one person familiar with directors' thinking. But employees approached board members warily because they were scared of potential repercussions of Altman finding out they had spoken out against him, the person said.
Two other interesting details from the Post's article:

• While over 95% of the company's employees signed an open letter after Altman's firing demanding his return, "On social media, in news reports and on the anonymous app Blind, which requires members to sign up with a work email address to post, people identified as current OpenAI employees also described facing intense peer pressure to sign the mass-resignation letter."

• The Post also spotted "a cryptic post" on X Wednesday from OpenAI co-founder and chief scientist Ilya Sutskever about lessons learned over the past month: "One such lesson is that the phrase 'the beatings will continue until morale improves' applies more often than it has any right to,'" (The Post adds that "The tweet was quickly deleted.")

The Post also reported in November that "Before OpenAI, Altman was asked to leave by his mentor at the prominent start-up incubator Y Combinator, part of a pattern of clashes that some attribute to his self-serving approach."

WindBourne shares a report: Global carbon emissions from fossil fuels reached record levels again in 2023, as experts warned that the projected rate of warming had not improved over the past two years. The world is on track to have burned more coal, oil and gas in 2023 than it did in 2022, according to a report by the Global Carbon Project, pumping 1.1% more planet-heating carbon dioxide into the atmosphere at a time when emissions must plummet to stop extreme weather from growing more violent.

The finding comes as world leaders meet in Dubai for the fraught Cop28 climate summit. In a separate report published on Tuesday, Climate Action Tracker (CAT) raised its projections slightly for future warming above the estimates it made at a conference in Glasgow two years ago. As carbon clogs the atmosphere, trapping sunlight and baking the planet, the climate is growing more hostile to human life. The growth in CO2 emissions had slowed substantially over the past decade, the Global Carbon Project found, but the amount emitted each year had continued to rise. It projected that total CO2 emissions in 2023 would reach a record high of 40.9 gigatons. If the world continued to emit CO2 at that rate, the international team of more than 120 scientists found, it would burn through the remaining carbon budget for a half-chance of keeping global heating to 1.5C (2.7F) above pre-industrial temperatures in just seven years. In 15 years, the scientists estimated, the budget for 1.7C would be gone too.

U.S. antitrust regulators told a federal appeals court Wednesday that a federal judge got it wrong when she allowed Microsoft's $69 billion purchase of Activision to close. Reuters reports: Speaking for the Federal Trade Commission, lawyer Imad Abyad argued that the lower-court judge held the agency to too high a standard, effectively requiring it to prove that the deal was anticompetitive. He told a three-judge appeals court panel in California that the FTC had only to show that Microsoft had the ability and incentive to withhold Activision's games from rival game platforms to prove the agency's case. He said the FTC "showed that in the past that's what Microsoft did," referring to allegations that Microsoft made some Zenimax games exclusive after buying that company.

Speaking for Microsoft, lawyer Rakesh Kilaru called the FTC case "weak" and said that the agency had asked the lower-court judge for too much leeway. "It is also clear that the standard can't be as low as the FTC is suggesting," he said. "It can't be kind of a mere scintilla of evidence." He argued that the agency failed to show that Microsoft had an incentive to withhold "Call of Duty" from rival gaming platforms. The judges actively questioned both attorneys, with Judge Daniel Collins pressing the FTC's attorney on how concessions that Microsoft gave British antitrust enforcers affect the U.S. market. He also appeared to take issue with Abyad's assertions that more analysis of the deal was necessary, especially since Microsoft had struck agreements with rivals recently, including one with Sony this past summer. "This was not a rush job on the part of the FTC," he said.

Two antitrust scholars who listened to the arguments said the FTC faced a tough slog to prevail. A finding of "clear error" by a lower court judge is "really stark," said Alden Abbott, a former FTC general counsel, comparing it to the idea that a court ignored key evidence from a witness. Abbott said the appeals court noted that the trial judge had considered "a huge amount of record evidence."

Twitch, the popular video streaming service, plans to shut down its business in South Korea on February 27 after finding that operating in one of the world's largest esports markets is "prohibitively expensive." From a report: Twitch CEO Dan Clancy said the firm undertook a "significant effort" to reduce the network costs to operate in Korea, but ultimately the fees to operate in the East Asian nation was still 10 times more expensive than in most other countries. The ceasing of operations in Korea is a "unique situation," he wrote in a blog post.

South Korea's expensive internet fees have led to legal fights -- streaming giant Netflix unsuccessfully sued a local broadband supplier last year to avoid paying usage charges, but Seoul's court ruled that Netflix must contribute to the network costs enabling its half-billion-dollar Korean business. Twitch attempted to lower its network costs by experimenting with a peer-to-peer model and then downgrading the streaming quality to 720p video resolution, Clancy said. While these efforts helped the firm lower its network costs, it wasn't enough.

An anonymous reader writes: People spend one-third of their lives asleep. What if employees could work during that time ... in their dreams? Prophetic, a venture-backed startup founded earlier this year, wants to help workers do just that. Using a headpiece the company calls the "Halo," Prophetic says consumers can induce a lucid dream state, which occurs when the person having a dream is aware they are sleeping. The goal is to give people control over their dreams, so they can use that time productively. A CEO could practice for an upcoming board meeting, an athlete could run through plays, a web designer could create new templates -- "the limiting factor is your imagination," founder and CEO Eric Wollberg told Fortune.

Consumer devices claiming to induce lucid dream states aren't new. Headbands, eye masks, and boxes with electrodes that stick to the forehead all populate the market. Even some supplements claim to do the trick. But there's still an appetite for new technologies, since the potential for creativity and problem-solving is so great and since many on the market don't work to the extent they promise, a dreaming expert told Fortune. The potential of lucid dreaming is less about conquering specific problems and more about finding new, creative ways to approach topics that a sleeper couldn't previously fathom. For example, a mathematician might not reach a specific, numerical answer to a math problem while asleep, but the lucid dream allows them to explore new strategies to tackle the equation while awake. Halos will cost around $1,500 to $2,000 each.

Traumatic memories had their own neural mechanism, brain scans showed, which may help explain their vivid and intrusive nature. From a report: At the root of post-traumatic stress disorder, or PTSD, is a memory that cannot be controlled. It may intrude on everyday activity, thrusting a person into the middle of a horrifying event, or surface as night terrors or flashbacks. Decades of treatment of military veterans and sexual assault survivors have left little doubt that traumatic memories function differently from other memories. A group of researchers at Yale University and the Icahn School of Medicine at Mount Sinai set out to find empirical evidence of those differences.

The team conducted brain scans of 28 people with PTSD while they listened to recorded narrations of their own memories. Some of the recorded memories were neutral, some were simply "sad," and some were traumatic. The brain scans found clear differences, the researchers reported in a paper published on Thursday in the journal Nature Neuroscience. The people listening to the sad memories, which often involved the death of a family member, showed consistently high engagement of the hippocampus, part of the brain that organizes and contextualizes memories. When the same people listened to their traumatic memories -- of sexual assaults, fires, school shootings and terrorist attacks -- the hippocampus was not involved.

[...] Indeed, the authors conclude in the paper, "traumatic memories are not experienced as memories as such," but as "fragments of prior events, subjugating the present moment." The traumatic memories appeared to engage a different area of the brain -- the posterior cingulate cortex, or P.C.C., which is usually involved in internally directed thought, like introspection or daydreaming. The more severe the person's PTSD symptoms were, the more activity appeared in the P.C.C. What is striking about this finding is that the P.C.C. is not known as a memory region, but one that is engaged with "processing of internal experience," Dr. Schiller said.

Astronomers have discovered six planets orbiting a bright star in perfect resonance. The star system, 100 light-years from Earth, was described on Wednesday in a paper published in the journal Nature. From a report: The discovery of the system could give astronomers a unique opportunity to trace the evolution of these worlds to when they first formed, and potentially offer insights into how our solar system got to be the way it is today. "It's like looking at a fossil," said Rafael Luque, an astronomer at the University of Chicago who led the study. "The orbits of the planets today are the same as they were a billion years ago."

Researchers think that when planets first form, their orbits around a star are in sync. That is, the time it takes for one planet to waltz around its host star might be the same amount of time it takes for a second planet to circle exactly twice, or exactly three times. Systems that line up like this are known as orbital resonances. But, despite the theory, finding resonances in the Milky Way is rare. Only 1 percent of planetary systems still preserve this symmetry.

Most of the time, planetary orbits get knocked out of sync by an event that upsets the gravitational balance of the system. That could be a close encounter with another star, the formation of a massive planet like Jupiter, or a giant impact from space on one planet that causes a ripple effect in other orbits. When this happens, Dr. Luque said, planetary orbits become too chaotic to mathematically describe, and knowledge of their evolution is indecipherable. Astronomers are lucky to find even one pair of exoplanets in resonance. But in the newly discovered star system, there are a whopping five pairs, because all six planets have orbits that are in sync with one another. Dr. Luque described it as "the 1 percent of the 1 percent."

Google Drive users are reporting files mysteriously disappearing from the service, with some posters on the company's support forums claiming six or more months of work have unceremoniously vanished. From a report: The issue has been rumbling for a few days, with one user logging into Google Drive and finding things as they were in May 2023. According to the poster, almost everything saved since then has gone, and attempts at recovery failed. Others chimed in with similar experiences, and one claimed that six months of business data had gone AWOL. There is little information regarding what has happened; some users reported that synchronization had simply stopped working, so the cloud storage was out of date.

Others could get some of their information back by fiddling with cached files, although the limited advice on offer for the affected was to leave things well alone until engineers come up with a solution. A message purporting to be from Google support also advised not to make changes to the root/data folder while engineers investigate the issue. Some users speculated that it might be related to accounts being spontaneously dropped. We've asked Google for its thoughts and will update should the search giant respond.
