Renewable energy use and reduced energy use overall have helped carbon emissions remain flat or below average as the global economy continued to grow over the years. But, as new research has found, government policy also appears to play a large role. Slashdot reader AmiMoJo shares a report from Ars Technica: The researchers started by identifying countries that show a "peak and decline" pattern of carbon emissions since the 1990s. They came up with 18, all but one of them in Europe -- the exception is the United States. For comparison, they created two different control groups of 30 countries, neither of which has seen emissions decline. One group saw high GDP growth, while the second saw moderate economic growth; in the past, these would have been associated with corresponding changes in emissions. Within each country, the researchers looked into whether there were government energy policies that could influence the trajectory of emissions. They also examined four items that could drive changes in emissions: total energy use, share of energy provided by fossil fuels, the carbon intensity of the overall energy mix, and efficiency (as measured by energy losses during use). On average, emissions in the decline group dropped by 2.4 percent over the decade between 2005 and 2015.

Half of this drop came from lowering the percentage of fossil fuels used, with renewables making a large contribution; another 35 percent came from a drop in energy use. But the most significant factor varied from country to country. Austria, Finland, and Sweden saw a drop in the share of fossil fuels within their energy mix. In contrast, a drop in total energy use was the biggest factor for France, Ireland, the Netherlands, Spain, and the United Kingdom. The U.S. was an odd one out, with all four possible factors playing significant roles in causing emissions to drop. For the two control groups, however, there was a single dominant factor: total energy use counted for 75 and 80 percent of the change in the low- and high-economic growth groups, respectively. But there was considerably more variability in the low-economic growth group. All of the high-growth group saw increased energy use contribute 60 percent of the growth in emissions or more. In contrast, some of the low-growth group actually saw their energy use drop. So why are some countries so successful at dropping their emissions? Part of it is likely to be economic growth, but the biggest reason may have to do with government policies. "By 2015, the countries in the group that saw declining emissions had an average of 35 policies that promoted renewable energy and another 23 that promoted energy efficiency," reports Ars Technica. "Both of those numbers are significantly higher than the averages for the control groups. And there's evidence that these policies are effective. The number of pro-efficiency policies correlated with the drop in energy use, while the number of renewable policies correlated with the drop in the share of fossil fuels."

FedEx is the latest company to join the delivery robot craze. The company said Wednesday it will test a six-wheeled, autonomous robot called the SameDay Bot in Memphis, Tenn. this summer and plans to expand to more cities. From a report: It's partnering with major brands, including Walmart, Target, Pizza Hut and AutoZone, to understand how delivery robots could help other businesses. FedEx's interest highlights how businesses are increasingly focused on automating deliveries. It also raises concerns about the impact on cities and employment, as robots crowd sidewalks and delivery jobs are automated. FedEx's robot has a top speed of 10 mph and can carry about 100 pounds. A company spokesman said its typical speed would vary depending on the route. The robot relies on sensors typically used on self-driving cars to identify and avoid pedestrians.

Bismillah writes: Researchers have published the results of exploring how vulnerable Thunderbolt is to DMA attacks, and the answer is "very." Be careful what you plug into that USB-C port. Yes, the set of vulnerabilities has a name: "Thunderclap." "Thunderbolt, which is available through USB-C ports on modern laptops, provides low-level direct memory access (DMA) at much higher privilege levels than regular universal serial bus peripherals," reports ITNews, citing a paper published from a team of researchers from the University of Cambridge, Rice University and SRI International. "This opens up laptops, desktops and servers with Thunderbolt input/output ports and PCI-Express connectors to attacks using malicious DMA-enabled peripherals. The main defense against the above attacks is the input-output memory management unit (IOMMU) that allows devices to access only the memory needed for the job to be done. Enabling the IOMMU to protect against DMA attacks comes at a high performance cost however. Most operating systems trade off security for performance gains, and disable the IOMMU by default."

"Apple's macOS uses the IOMMU, but even with the hardware defense enabled, the researchers were able to use a fake network card to read data traffic that is meant to be confined to the machine and never leave it," the report adds. "The network card was also able to run arbitrary programs at system administrator level on macOS and could read display contents from other Macs and keystrokes from a USB keyboard. Apple patched the vulnerability in macOS 10.12.4 that was released in 2016, but the researchers say the more general scope of such attacks remains relevant."

A startup called Veo Robotics is preparing to roll out sensor technology that lets industrial robots work safely side-by-side with humans. "Veo's proprietary technology uses lidar sensors to create real-time maps of factory work spaces, so that robots can slow or stop completely when human workers get too close," Bloomberg reports. From the report: There are more than 2 million industrial robots in operation worldwide, mostly toiling inside metal safety cages. The seclusion is fine for repetitive tasks that can be done entirely by machines, such as arc welding, but the majority of work even in the most automated factories requires involvement of people. Embedding force sensors into industrial limbs is one way to prevent them from plowing through obstacles, but the same technology that makes the arms safe also makes them weak. Most so-called cobots cannot handle weights heavier than 10 kilograms (22 pounds). Computer vision offers a way to get robots into more complex environments, without compromising their strength. Another obstacle is that manufacturers increasingly have to make multiple products on the same assembly line and are constantly retooling their production to accommodate shifting consumer tastes. There are also not enough workers to do the job.

Veo, based in Waltham, Massachusetts, is working closely with the world's biggest robot makers Fanuc Corp., Yaskawa Electric Corp. and Kuka AG. But Veo's first customers are likely to be car companies, manufacturers of durable goods such as household appliances and oil and gas equipment makers, where the shale revolution created demand for more customization. The technology could be used to get machines to present parts to human workers, for loading and unloading fixtures and in palletizing.

technology_dude writes: Google's DeepMind can predict wind patterns one day in advance. "Beginning last year, [Google and DeepMind] fed weather forecasts and existing turbine data into DeepMind's machine learning platform, which churned out wind power predictions 36 hours ahead of actual power generation," Engadget reports. "Google could then make supply commitments to power grids a full day before delivery." According to the report, this makes the energy generated by its wind turbines more valuable (by roughly 20%). Is this a blow to Big Blue who purchased The Weather Channel's Weather.com to showcase Watson, or is it news just because it's Google?

Microsoft CEO Satya Nadella is defending the company's $479 million contract with the Pentagon to supply augmented reality headsets to the U.S. military. "We made a principled decision that we're not going to withhold technology from institutions that we have elected in democracies to protect the freedoms we enjoy," he told CNN Business at Mobile World Congress. "We were very transparent about that decision and we'll continue to have that dialogue [with employees]," he added during the exclusive interview. From the report: Microsoft was awarded the contract to supply "Integrated Visual Augmentation System" prototypes to the U.S. military in November. The company could eventually deliver over 100,000 headsets under the contract. Microsoft's HoloLens augmented reality technology allows users to see the world around them, but with virtual graphics overlaid. The Israeli military, which has taken delivery of some HoloLens headsets, says the technology can be used to help commanders visualize the battlefield and field medics to consult doctors. According to procurement documents, the U.S. military is seeking a single platform that provides its forces with "increased lethality, mobility and situational awareness" in combat. Microsoft employees have recently circulated a letter addressed to Nadella and Brad Smith, the company's president and chief legal officer, arguing that the company should not supply its HoloLens technology to the U.S. military. "It's not about taking arbitrary action by a single company, it's not about 50 people or 100 people or even 100,000 people in a company," he said. "It's really about being a responsible corporate citizen in a democracy."

The SD Association has unveiled microSD Express, a new format that will bring speeds of up to 985 MB/s to the tiny memory cards used in smartphones and other devices. From a report: Like SD Express, it exploits the NVMe 1.3 and PCIe 3.1 interfaces used in PCs to power high-speed SSDs. The tech is incorporated onto the second row of microSD pins, so the cards will work faster in next-gen devices while maintaining backward compatibility with current microSD tech. PCIe 3.1 allows for low power sub-states, so the cards will not only offer much (much) higher transfer speeds, but consume less power than regular microSD cards. It'll also open up features like bus mastering, which lets memory cards communicate with other components without going through the CPU first.

PepsiCo is kicking off a four-year restructuring plan that is expected to cost the company hundreds of millions of dollars in severance pay. "This week, PepsiCo employees in offices including Plano, Texas, and the company's headquarters in Purchase, New York, were alerted that they are being laid off," reports Business Insider, citing two people directly impacted by the layoffs.

The latest job cuts come after CFO Hugh Johnston told CNBC that the company plans to lay off workers in positions that can be automated. CEO Ramon Laguarta said on Friday that PepsiCo is "relentlessly automating and merging the best of our optimized business models with the best new thinking and technologies." From a report: This week, PepsiCo employees in offices including Plano, Texas, and the company's headquarters in Purchase, New York, were alerted that they are being laid off, according to two people who were directly impacted by the layoffs. These two workers were granted anonymity in order to speak frankly without risking professional ramifications. At least some of the workers who were alerted about layoffs will continue to work at PepsiCo until late April as they train their replacements in the coming weeks, the two workers told Business Insider.

By PepsiCo's own estimates, the company's layoffs are expected to be a multimillion-dollar project in 2019. Last Friday, PepsiCo announced in a filing with the Securities and Exchange Commission (SEC) that it is expected to incur $2.5 billion in pretax restructuring costs through 2023, with 70% of charges linked to severance and other employee costs. The company is also planning to close factories, with an additional 15% tied to plant closures and "related actions." Roughly $800 million of the $2.5 billion is expected to impact 2019 results, in addition to the $138 million that was included in 2018 results, the company said in the SEC filing.

Developers and Intel officials have told Axios that Apple is expected to move its Mac line to custom ARM-based chips as soon as next year. "Bloomberg offered a bit more specificity on things in a report on Wednesday, saying that the first ARM-based Macs could come in 2020, with plans to offer developers a way to write a single app that can run across iPhones, iPads and Macs by 2021," reports Axios. "The first hints of the effort came last year when Apple offered a sneak peek at its plan to make it easier for developers to bring iPad apps to the Mac." From the report: If anything, the Bloomberg timeline suggests that Intel might actually have more Mac business in 2020 than some had been expecting. The key question is not the timeline but just how smoothly Apple is able to make the shift. For developers, it will likely mean an awkward period of time supporting new and classic Macs as well as new and old-style Mac apps. The move could give developers a way to reach a bigger market with a single app, although the transition could be bumpy. For Intel, of course, it would mean the loss of a significant customer, albeit probably not a huge hit to its bottom line.

An anonymous reader quotes a report from Quartz: Riders in Switzerland and New Zealand have reported the front wheels of their electric scooters locking suddenly mid-ride, hurling riders to the ground. The malfunction has resulted in dozens of injuries ranging from bruises to broken jaws. Lime pulled all its scooters from Swiss streets in January when reports of the incidents surfaced there. When the city of Auckland, New Zealand voted to suspend the company earlier this week following 155 reported cases of sudden braking, the company acknowledged that a software glitch was causing the chaos. The company claims that fewer than 0.0045% of all rides worldwide have been affected, adding that "any injury is one too many." An initial fix reduced the number of incidents, it said, and a final update underway on all scooters will soon be complete. "Recently we detected a bug in the firmware of our scooter fleet that under rare circumstances could cause sudden excessive braking during use," Lime wrote in a blog post Saturday. "[I]n very rare cases -- usually riding downhill at top speed while hitting a pothole or other obstacle -- excessive brake force on the front wheel can occur, resulting in a scooter stopping unexpectedly."

"A scientist working for the U.S. Navy has filed for a patent on a room-temperature superconductor, representing a potential paradigm shift in energy transmission and computer systems," reports Phys.org: Salvatore Cezar Pais is listed as the inventor on the Navy's patent application made public by the U.S. Patent and Trademark Office on Thursday. The application claims that a room-temperature superconductor can be built using a wire with an insulator core and an aluminum PZT (lead zirconate titanate) coating deposited by vacuum evaporation with a thickness of the London penetration depth and polarized after deposition.

An electromagnetic coil is circumferentially positioned around the coating such that when the coil is activated with a pulsed current, a non-linear vibration is induced, enabling room temperature superconductivity. "This concept enables the transmission of electrical power without any losses and exhibits optimal thermal management (no heat dissipation)," according to the patent document, "which leads to the design and development of novel energy generation and harvesting devices with enormous benefits to civilization."
Long-time Slashdot reader resistant writes: NextBigFuture says the same individual appears to have made other startling claims that arguably stretch the boundaries of belief, such as a "high-frequency gravitational wave generator" that could supposedly drive a spaceship without conventional propellants as well as an "inertial mass reduction device." Prudence would appear to dictate examining these and other claims by Mr. Salvatore Cezar Pais with great caution.

A new adsorbent material "soaks up uranium from seawater, leaving interfering ions behind," reports the ACS's Chemical & Engineering News, in an article shared by webofslime: The world's oceans contain some 4 billion metric tons of dissolved uranium. That's roughly 1,000 times as much as all known terrestrial sources combined, and enough to fuel the global nuclear power industry for centuries. But the oceans are so vast, and uranium's concentration in seawater is so low -- roughly 3 ppb -- that extracting it remains a formidable challenge... Researchers have been looking for ways to extract uranium from seawater for more than 50 years...

Nearly 20 years ago, the Japan Atomic Energy Agency (JAEA) confirmed that amidoxime-functionalized polymers could soak up uranium reliably even under harsh marine conditions. But that type of adsorbent has not been implemented on a large scale because it has a higher affinity for vanadium than uranium. Separating the two ions raises production costs. Alexander S. Ivanov of Oak Ridge National Laboratory, together with colleagues there and at Lawrence Berkeley National Laboratory and other institutions, may have come up with a solution. Using computational methods, the team identified a highly selective triazine chelator known as H2BHT that resembles iron-sequestering compounds found in bacteria and fungi.... H2BHT exhibits little attraction for vanadium but has roughly the same affinity for uranyl ions as amidoxime-based adsorbents do.

An anonymous reader quotes the Guardian: An American 14-year-old has reportedly become the youngest known person in the world to create a successful nuclear reaction. The Open Source Fusor Research Consortium, a hobbyist group, has recognised the achievement by Jackson Oswalt, from Memphis, Tennessee, when he was aged 12 in January 2018....

The enterprising teenager said he transformed an old playroom in his parents' house into a nuclear laboratory with $10,000 (£7,700) worth of equipment that uses 50,000 volts of electricity to heat deuterium gas and fuse the nuclei to release energy. "The start of the process was just learning about what other people had done with their fusion reactors," Jackson told Fox. "After that, I assembled a list of parts I needed. I got those parts off eBay primarily and then oftentimes the parts that I managed to scrounge off of eBay weren't exactly what I needed. So I'd have to modify them to be able to do what I needed to do for my project...."

[S]cientists are likely to remain sceptical until Oswalt's workings are subject to verification from an official organisation and are published in an academic journal. Still, the teenager may now have usurped the previous record holder, Taylor Wilson, who works in nuclear energy research after achieving fusion aged 14.

MojoKid writes: NVIDIA has launched yet another graphics card today based on the company's new Turing GPU. This latest GPU, however, doesn't support NVIDIA's RTX ray-tracing technology or its DLSS (Deep Learning Super Sampling) image quality tech. The new GeForce GTX 1660 Ti does, however, bring with it all of the other GPU architecture improvements NVIDIA Turing offers. The new TU116 GPU on board the GeForce GTX 1660 Ti supports concurrent integer and floating point instructions (rather than serializing integer and FP instructions), and it also has a redesigned cache structure with double the amount of L2 cache versus their predecessors, while its L1 cache has been outfitted with a wider memory bus that ultimately doubles the bandwidth. NVIDIA's TU116 has 1,536 active CUDA cores, which is a decent uptick from the GTX 1060, but less than the current gen RTX 2060. Cards will also come equipped with 6GB of GDDR6 memory at 12 Gbps for 288GB/s of bandwidth. Performance-wise, the new GeForce GTX 1660 Ti is typically slightly faster than a previous gen GeFore GTX 1070, and much faster than a GTX 1060. Cards should be available at retail in the next few days, starting at $279.

An anonymous reader quotes a report from BuzzFeed News: A viral photo showing a camera in a Singapore Airlines in-flight TV display recently caused an uproar online. The image was retweeted hundreds of times, with many people expressing concern about the privacy implications. As it turns out, some seat-back screens in American Airlines' premium economy class have them, too. Sri Ray was aboard an American Airlines Boeing 777-200 flight to Tokyo in September 2018 when he noticed something strange: a camera embedded in the seat back of his entertainment system. The cameras are also visible in this June 2017 review of the airline's premium economy offering by the Points Guy, as well as this YouTube video by Business Traveller magazine.

American Airlines spokesperson Ross Feinstein confirmed to BuzzFeed News that cameras are present on some of the airlines' in-flight entertainment systems, but said "they have never been activated, and American is not considering using them." Feinstein added, "Cameras are a standard feature on many in-flight entertainment systems used by multiple airlines. Manufacturers of those systems have included cameras for possible future uses, such as hand gestures to control in-flight entertainment." After Twitter user Vitaly Kamluk saw a similar lens on Singapore Airlines and tweeted photos of the system last week, the airline responded from its official Twitter account, saying the cameras were "disabled." Still, the airlines could quell passengers' concerns by covering the lenses with a plastic cover, if indeed there is no use for the camera.

Canada is the newest frontier in the fight for the "right to repair" after an Ontario politician introduced a bill on Thursday that would ensure individuals and independent professionals can repair brand-name computers and phones cheaply and easily. From a report: Manufacturers make it incredibly difficult to repair our broken devices ourselves. Instead of taking a smashed phone to a local repair professional for an affordable fix, a complex matrix of trade secrets and government intervention often means consumers have to make a pricey trip to the Genius Bar or buy a new device entirely. This is bad for your wallet, but also bad for the planet.

Ontario Liberal Party MPP Michael Coteau ran into this issue head-first after his daughter dropped his Samsung smartphone. An official repair job from the manufacturer was more expensive than just getting a new phone from his carrier, he told me over the phone. "It's a shame," Coteau said, "because the Samsung S8 was very good for me. Everything was perfect. I would've kept using it. But now I've replaced it." On Thursday, Coteau introduced a private member's bill in provincial parliament that, if passed, would be the first "right to repair" law for electronic devices in North America. More than a dozen US states are currently considering similar bills, but nothing is on the books yet in the US or in Canada.

A group of researchers say that it will be difficult to avoid Spectre bugs in the future unless CPUs are dramatically overhauled. From a report: Google researchers say that software alone is not enough to prevent the exploitation of the Spectre flaws present in a variety of CPUs. The team of researchers -- including Ross McIlroy, Jaroslav Sevcik, Tobias Tebbi, Ben L Titzer and Toon Verwaest -- work on Chrome's V8 JavaScript engine. The researchers presented their findings in a paper distributed through ArXiv and came to the conclusion that all processors that perform speculative execution will always remain susceptible to various side-channel attacks, despite mitigations that may be discovered in future.

An anonymous reader writes: In case you missed the latest drama to take place in the YouTube tech community, Ars Technica reports how Vox Media attempted to copyright strike two reaction videos that mocked The Verge's terrible PC build guide video that could have ruined a $2,000 system for a beginner PC builder. That effort failed when the tech community sounded the alarms; YouTube removed the copyright strikes and Vox Media had to retract their takedown notice.

From the report: "Last week, The Verge got a reminder about the power of the Streisand effect after its lawyers issued copyright takedown requests for two YouTube videos that criticized -- and heavily excerpted -- a video by The Verge. Each takedown came with a copyright 'strike.' It was a big deal for the creators of the videos, because three 'strikes' in a 90-day period are enough to get a YouTuber permanently banned from the platform. T.C. Sottek, the Verge's managing editor, blamed lawyers at the Verge's parent company, Vox Media, for the decision. 'The Verge's editorial structure was involved zero percent in the decision to issue a strike,' Sottek said in a direct message. 'Vox Media's legal team did this independently and informed us of it after the fact.' The move sparked an online backlash. Verge editor Nilay Patel (who, full disclosure, was briefly a colleague of mine at The Verge's sister publication Vox.com), says that when he learned about the decision, he asked that the strike be rescinded, leading to the videos being reinstated. Still, Patel defended the lawyers' legal reasoning, arguing that the videos 'crossed the line' into copyright infringement. It's hard to be sure if this is true since there are very few precedents in this area of the law. But the one legal precedent I was able to find suggests the opposite: that this kind of video is solidly within the bounds of copyright's fair use doctrine."

dryriver writes: A lot of people probably remember the 1990s palmtop computers made by Psion fondly. The clamshell-design palmtops were pocketable, black and white, but had a working stylus and a fantastic tactile foldout QWERTY keyboard that you could type pretty substantial documents on or even write code with. A different company -- Planet Computers -- has now produced a spiritual successor to the old Psion palmtops called the Gemini PDA that is much like an old Psion but with the latest Android smartphone hardware in it and a virtually identical tactile keyboard. It can also dual boot to Linux (Debian, Ubuntu, Sailfish) alongside Android. The technical specs are a MediaTek deca-core processor, 4GB RAM, 64GB storage (plus microSD slot), 4G, 802.11c Wi-Fi, GPS, Bluetooth, eSIM support, and 4,220mAh battery. The screen measures in at 5.99-inches with a 2,160 x 1,080 (403ppi) resolution. The only thing missing seems to be the stylus -- but perhaps that would have complicated manufacturing of this niche-device in its first production run.

From a report: Logitech has announced it is bringing back the "legendary" (the company's word, not mine) MX518 gaming mouse. The announcement says "many consider [it] to be the finest gaming mouse of all time." I am definitely one of those people. Logitech first released the MX518 in 2005, as the successor to the already-pretty-good MX510 gaming mouse released in 2004. The MX518 was around for six years before Logitech tried to replace it with the G400 gaming mouse in 2011. I say "tried" because, well, it just wasn't the same. Logitech has finally admitted as much, after eight years of trying. The company is promising that the reborn MX518 will have the same shape and feel as the original. The materials have been updated, and there's a new "Nightfall" finish but, crucially, it's still an MX518.
