Wired visits Chula Vista, California (population: 275,487) — where since 2018 drones have been dispatched by police "teleoperators" monitoring 911 calls. ("Noise complaints, car accidents, overdoses, domestic disputes...") After nearly 20,000 drone flights, it's become the envy of other police departments, according to Wired's article, as other police departments "look to expand their use of unmanned aerial aircraft." The [Chula Vista] department says that its drones provide officers with critical intelligence about incidents they are responding to ahead of initiating in-person contact — which the CVPD says has reduced unnecessary police contacts, decreased response times, and saved lives. But a WIRED investigation paints a complicated picture of the trade-offs between public safety and privacy. In Chula Vista, drone flight paths trace a map of the city's inequality, with poorer residents experiencing far more exposure to the drones' cameras and rotors than their wealthier counterparts, a WIRED analysis of nearly 10,000 drone flight records from July 2021 to September 2023 found. The drones, often dispatched for serious incidents like reports of armed individuals, are also routinely deployed for minor issues such as shoplifting, vandalism, and loud music. [Drones are sent in response to about 1 in every 14 calls.] Early in the Covid-19 pandemic, the city even used drones to broadcast public service announcements to homeless encampments. Despite the police promoting the benefits of the "Drone as First Responder" program, residents who encounter the technology day-to-day report feeling constantly watched. Some say they are afraid to spend time in their backyards; they fear that the machines are following them down the street, spying on them while they use the public pool or change their clothes. One resident says that he was so worried that the drones were harassing him that he went to the emergency room for severe depression and exhaustion. [A 60-year-old professor told Wired that the sound of drones kept them awake at night.] The police drones, equipped with cameras and zoom lenses powerful enough to capture faces clearly and constantly recording while in flight, have amassed hundreds of hours of video footage of the city's residents. Their flight paths routinely take them over backyards and above public pools, high schools, hospitals, churches, mosques, immigration law firms, and even the city's Planned Parenthood facility. Privacy advocates argue that the extensive footage captured by the drones makes it difficult to distinguish between flights responding to specific incidents and mass surveillance from the sky. Department secrecy around the recordings remains the subject of ongoing litigation... At the time of our analysis, approximately one in 10 drone flights listed on the department's transparency portal lacked a stated purpose and could not be connected to any relevant 911 call.

"Police and search and rescue forces worldwide are increasingly using robots to assist in carrying out their operations," writes Interesting Engineering. "Now, the Dutch police are looking at employing AI-powered autonomous robot dogs in drug lab raids to protect officers from criminal risks, hazardous chemicals, and explosions." New Scientist's Matthew Sparkes (also a long-time Slashdot reader) shares this report: Dutch police are planning to use an autonomous robotic dog in drug lab raids to avoid placing officers at risk from criminals, dangerous chemicals and explosions. If tests in mocked-up scenarios go well, the artificial intelligence-powered robot will be deployed in real raids, say police. Simon Prins at Politie Nederland, the Dutch police force, has been testing and using robots in criminal investigations for more than two decades, but says they are only now growing capable enough to be practical for more... Some context from Interesting Engineering: The police force in the Netherlands carries out such raids at least three to four times a week... Since 2021, the force has already been using a Spot quadruped, fitted with a robotic arm, from Boston Dynamics to carry out drug raids and surveillance. However, the Spot is remotely controlled by a handler... [Significant technological advancements] have prompted the Dutch force to explore fully autonomous operations with Spot. Reportedly, such AI-enabled autonomous robots are expected to inspect drug labs, ensure no criminals are present, map the area, and identify dangerous chemicals... Initial tests by force suggest that Spot could explore and map a mock drug lab measuring 15 meters by 20 meters. It was able to find hazardous chemicals and put them away into a designated storage container. Their article notes that Spot "can do laser scans and visual, thermal, radiation, and acoustic inspections using add-on payloads and onboard cameras." (A video from Boston Dynamics — the company behind Spot — also seems to show the robot dog spraying something on a fire.) The video seems aimed at police departments, touting the robot dog's advantages for "safety and incident response": Enables safer investigation of suspicious packages Detection of hazardous chemicals De-escalation of tense or dangerous situations Get eyes on dangerous situations It also notes the robot "can be operated from a safe distance," suggesting customers "Use Spot(R) to place cameras, radios, and more for tactical reconnaissance."

"The first European Space Agency instrument to land on the Moon has detected the presence of negative ions on the lunar surface produced through interactions with the solar wind," according to a statement from the agency, collecting over three hours of data, "three times more than what the science teams needed for mission success..." The solar wind is a constant flow of radiation and particles from the Sun. Earth's magnetic field acts as a shield. In contrast, the Moon has no magnetic field and a very tenuous atmosphere, called the exosphere. When the solar wind hits the Moon,âthe surface reacts, kicking up secondary particles... While the positively charged particles have been measured from orbit before, measuring negative particles was a challenge. Negative ions are short-lived and cannot make it to orbit. The instrument was dropped off by China's Chang'e-6 lunar lander, and Europe's ground stations are also providing support for that mission. Futurism reports: Within just over 48 hours, China's Chang'e-6 lunar touched down on the far side of the Moon, successfully scooped up samples, and kicked off once again. It was an extraordinary feat, representing the first-ever samples ever collected from the side of the Moon that permanently faces away from us. During its brief visit, the lander also dropped off several scientific payloads on the lunar service, including the European Space Agency's Negative Ions at the Lunar Surface instrument. The lander also unfurled China's red and gold flag for the first time on the far side of the moon, according to the Associated Press. And then... Its ascender lifted off Tuesday morning at 7:38 a.m. Beijing time, with its engine burning for about six minutes as it entered a preset orbit around the moon, the China National Space Administration said. The agency said the spacecraft withstood a high temperature test on the lunar surface, and acquired the samples using both drilling and surface collection before stowing them in a container inside the ascender of the probe as planned. The container will be transferred to a reentry capsule that is due to return to Earth in the deserts of China's Inner Mongolia region about June 25. The samples "could help researchers figure out why the moon's two sides are so starkly different," writes Science News: Spacecraft observations of the farside show very little volcanic activity. Some scientists suspect that this is because the nearside crust is much thinner, which would have allowed more magma to come up from below the surface, says Kerri Donaldson Hanna, a planetary geologist at the University of Central Florida in Orlando. There is evidence that some volcanism occurred in the South Pole-Aitken basin and in Apollo crater, though it appears this activity happened roughly 3.5 billion years ago. It's possible the impact that created both Aiken and Apollo weakened the lunar crust, forming fractures and allowing magma to flow. The samples onboard Chang'e-6 could contain clues as to whether or not this happened. Both Chinese and international researchers will be able to study the material. Donaldson Hanna is looking forward to seeing what insights will be gleaned from Chang'e-6 as well as future landers, such as those in NASA's Commercial Lunar Payload Services program.

America's Justice Department "indicted the creators of an application that helps people spend their bitcoins anonymously," writes Reason.com: They're accused of "conspiracy to commit money laundering." Why "conspiracy to commit" as opposed to just "money laundering"? Because they didn't hold anyone else's money or do anything illegal with it. They provided a privacy tool that may have enabled other people to do illegal things with their bitcoin... What this tool does is offer what's known as a "coinjoin," a method for anonymizing bitcoin transactions by mixing them with other transactions, as the project's founder, Keonne Rodriguez, explained to Reason in 2022: "I think the best analogy for it is like smelting gold," he said. "You take your Bitcoin, you add it into [the conjoin protocol] Whirlpool, and Whirlpool smelts it into new pieces that are not associated to the original piece." Reason argues that providing the tool isn't a crime, just like selling someone a kitchen knife isn't a crime: The government's decision to indict Rodriguez and his partner William Lonergan Hill is also an attack on free speech because all they did was write open-source code and make it widely available. "It is an issue of a chilling effect on free speech," attorney Jerry Brito, who heads up the cryptocurrency nonprofit Coin Center, told Reason after the U.S. Treasury went after the creators of another piece of anonymizing software... The most important thing about bitcoin, and money like it, isn't its price. It's the check it places on the government's ability to devalue, censor, and surviel our money. Creators of open-source tools like Samourai Wallet should be celebrated, not threatened with a quarter-century in a federal prison. Long-time Slashdot reader SonicSpike shared the article...

Last week America's energy secretary cheered the startup of a fourth nuclear reactor at a Georgia power plant, calling it "the largest producer of clean energy, and the largest producer of electricity in the United States" after a third reactor was started up there in December. From the U.S. Energy Department's transcript of the speech: Each year, Units 3 and 4 are going to produce enough clean power to power 1 million homes and businesses, enough energy to power roughly 1 in 4 homes in Georgia. Preventing 10 million metric tons of carbon dioxide pollution annually. That, by the way, is like planting more than 165 million trees every year! And that's not to mention the historic investments that [electric utility] Southern has made on the safety front, to ensure this facility meets — and exceeds — the highest operating standards in the world.... To reach our goal of net zero by 2050, we have to at least triple our current nuclear capacity in this country. That means we've got to add 200 more gigawatts by 2050. Okay, two down, 198 to go! In building [Unit] 4, we've solved our greatest design challenges. We've stood up entire supply chains.... And so it's time to cash in on our investments by building more. More of these facilities. The Department of Energy's Loan Programs Office stands ready to help, with hundreds of billions of dollars in what we call Title 17 loans... Since the President signed the Inflation Reduction Act and the Bipartisan Infrastructure Law, companies across the nation have announced 29 new or expanded nuclear facilities — across 16 states — representing about 1,600 potential new jobs. And the majority of those projects will expand the domestic uranium production and fuel fabrication, strengthening these critical supply chains... Bottom line is, in short, we are determined to build a world-class nuclear industry in the United States, and we're putting our money where our mouth is. America's Energy Secretary told the Washington Post that "Whether it happens through small modular reactors, or AP1000s, or maybe another design out there worthy of consideration, we want to see nuclear built." The Post notes the Energy department gave a $1.5 billion loan to restart a Michigan power plant which was decommissioned in 2022. "It would mark the first time a shuttered U.S. nuclear plant has been reactivated." "But in this country with 54 nuclear plants across 28 states, restarting existing reactors and delaying their closure is a lot less complicated than building new ones." When the final [Georgia] reactor went online at the end of April, the expansion was seven years behind schedule and nearly $20 billion over budget. It ultimately cost more than twice as much as promised, with ratepayers footing much of the bill through surcharges and rate hikes... Administration officials say the country has no choice but to make nuclear power a workable option again. The country is fast running short on electricity, demand for power is surging amid a boom in construction of data centers and manufacturing plants, and a neglected power grid is struggling to accommodate enough new wind and solar power to meet the nation's needs... As the administration frames the narrative of the plant as one of perseverance and innovation that clears a path for restoring U.S. nuclear energy dominance, even some longtime boosters of the industry question whether this country will ever again have a vibrant nuclear energy sector. "It is hard for me to envision state energy regulators signing off on another one of these, given how badly the last ones went," said Matt Bowen, a nuclear scholar at the Center on Global Energy Policy at Columbia University, who was an adviser on nuclear energy issues in the Obama administration. The article notes there are 19 AP1000 reactors (the design used at the Georgia plant) in development around the world. "None of them are being built in the United States."

"Researchers observed a new Linux variant of the TargetCompany ransomware family that targets VMware ESXi environments," reports BleepingComputer: In a report Wednesday, cybersecurity company Trend Micro says that the new Linux variant for TargetCompany ransomware makes sure that it has administrative privileges before continuing the malicious routine... Once on the target system, the payload checks if it runs in a VMware ESXi environment by executing the 'uname' command and looking for 'vmkernel.' Next, a "TargetInfo.txt" file is created and sent to the command and control (C2) server. It contains victim information such as hostname, IP address, OS details, logged-in users and privileges, unique identifiers, and details about the encrypted files and directories. The ransomware will encrypt files that have VM-related extensions (vmdk, vmem, vswp, vmx, vmsn, nvram), appending the ".locked" extension to the resulting files. Finally, a ransom note named "HOW TO DECRYPT.txt" is dropped, containing instructions for the victim on how to pay the ransom and retrieve a valid decryption key. "After all tasks have been completed, the shell script deletes the payload using the 'rm -f x' command so all traces that can be used in post-incident investigations are wiped from impacted machines."

Long-time Slashdot reader theodp writes: "Great news, Louisiana!" tech-backed Code.org exclaimed Wednesday in celebratory LinkedIn, Facebook, and Twitter posts. Louisiana is "officially the 10th state to make computer science a [high school] graduation requirement. Huge thanks to Governor Jeff Landry for signing the bill and to our legislative champions, Rep. Jason Hughes and Sen. Thomas Pressly, for making it happen! This means every Louisiana student gets a chance to learn coding and other tech skills that are super important these days. These skills can help them solve problems, think critically, and open doors to awesome careers!" Representative Hughes, the sponsor of HB264 — which calls for each public high school student to successfully complete a one credit CS course as a requirement for graduation and also permits students to take two units of CS instead of studying a Foreign Language — tweeted back: "HUGE thanks @codeorg for their partnership in this effort every step of the way! Couldn't have done it without [Code.org Senior Director of State Government Affairs] Anthony [Owen] and the Code.org team!" Code.org also on Wednesday announced the release of its 2023 Impact Report, which touted its efforts "to include a requirement for every student to take computer science to receive a high school diploma." Since its 2013 launch, Code.org reports it's spent $219.8 million to push coding into K-12 classrooms, including $19 million on Government Affairs (Achievements: "Policies changed in 50 states. More than $343M in state budgets allocated to computer science."). In Code.org by the Numbers, the nonprofit boasts that 254,683 students started Code.org's AP CS Principles course in the academic year (2025 Goal: 400K), while 21,425 have started Code.org's new Amazon-bankrolled AP CS A course. Estimates peg U.S. public high school enrollment at 15.5M students, annual K-12 public school spending at $16,080 per pupil, and an annual high school student course load at 6-8 credits...

"Rust is the fastest-growing programming language, with its developer community doubling in size over the past two years," writes The New Stack, "yet JavaScript remains the most popular language with 25.2 million active developers, according to the results of a recent survey." The 26th edition of SlashData's Developer Nation survey showed that the Rust community doubled its number of users over the past two years — from two million in the first quarter of 2022 to four million in the first quarter of 2024 — and by 33% in the last 12 months alone. The SlashData report covers the first quarter of 2024. "Rust has developed a passionate community that advocates for it as a memory-safe language which can provide great performance, but cybersecurity concerns may lead to an even greater increase," the report said. "The USA and its international partners have made the case in the last six months for adopting memory-safe languages...." "JavaScript's dominant position is unlikely to change anytime soon, with its developer population increasing by 4M developers over the last 12 months, with a growth rate in line with the global developer population growth," the report said. The strength of the JavaScript community is fueled by the widespread use of the language across all types of development projects, with at least 25% of developers in every project type using it, the report said. "Even in development areas not commonly associated with the language, such as on-device coding for IoT projects, JavaScript still sees considerable adoption," SlashData said. Also, coming in strong, Python has overtaken Java as the second most popular language, driven by the interest in machine learning and AI. The battle between Python and Java shows Python with 18.2 million developers in Q1 2024 compared to Java's 17.7 million. This comes about after Python added more than 2.1 million net new developers to its community over the last 12 months, compared to Java which only increased by 1.2 million developers... Following behind Java there is a six-million-developer gap to the next largest community, which is C++ with 11.4 million developers, closely trailed by C# with 10.2 million and PHP with 9.8 million. Languages with the smallest communities include Objective-C with 2.7 million developers, Ruby with 2.5 million, and Lua with 1.8 million. Meanwhile, the Go language saw its developer population grow by 10% over the last year. It had previously outpaced the global developer population growth, growing by 5Y% over the past two years, from three million in Q1 2022 to 4.7 million in Q1 2024. "TNS analyst Lawrence Hecht has a few different takeaways. He notes that with the exceptions of Rust, Go and JavaScript, the other major programming languages all grew slower than the total developer population, which SlashData says increased 39% over the last two years alone."

A worker at a retail store in an airport has been charged with stealing thousands of dollars in electronics and clothing, reports the Washington Post. But what's more interesting is what led to his arrest... A woman showed up at his home looking for the missing luggage that she'd tracked with her Apple Watch. CNN reports: Paola Garcia told CNN affiliate WPLG in Miami that she usually takes her suitcase onboard, but this time, she was told she had to check it. Garcia waited at least two hours for her pink roller bag, which contained an Apple MacBook, Apple iPad, Apple Watch, jewelry, high-end woman's clothing and toiletries. It never came out on the luggage belt. In her WPLG interview, Garcia said that Spirit Airlines told her that her luggage had been sent to her house. The luggage never came. But Garcia explored another avenue with her own electronic tracker. Garcia, not named in the affidavit, later pinged the electronic items inside the bag to try and locate them, and the ping showed them at an address in Fort Lauderdale, the affidavit said... While at the house, she took video and still pictures, where she saw "several pieces of luggage in the front of the home," none of which were her own, the affidavit said. Garcia told WPLG that she dialed 911. "The first thing I remember the police told me is: 'What are you doing here? This is so dangerous for you to be here.' " When a detective with the Broward County Sheriff's Office searched the address within the airport's employee databases, he found that Bazile reportedly lived at the address. Bazile was listed as working at a Paradies Lagardère Travel Retail store at the airport and was working on the day of the theft, according to the affidavit. So apparently when the airline said the luggage had been sent to her house — they were wrong. In fact when police contacted a store manager, "he provided the detective with internal CCTV footage from the day of the incident," CNN reports, "which allegedly showed Bazile entering the store's storage room with a pink shell roller bag, matching the description of the stolen bag, and rummaging through the luggage, the affidavit said. "He then appeared to take the MacBook and other smaller items out of the luggage and put them in other bags."

"Lansweeper's scans of its customers' networks found an awful lot of Linux boxes facing imminent end of life," reports the Register, "with no direct upgrade path." Belgian corporate network scanner vendor Lansweeper periodically collates some of the statistics collected by its users and publishes the results... This year's report says that while a third of its users' Linux machines run Ubuntu, second place goes to CentOS Linux [with 26.05%]. Back in 2020, Red Hat brought CentOS Linux 8's end of life forward from 2029 to the end of 2021. CentOS Linux 9 was canceled, CentOS Linux 8 is dead and gone, leaving only CentOS Linux 7. As we reported in May, CentOS 7's end of life is very close now — the end of June. After this month, no more updates. Of course, Red Hat will be happy to help you migrate to RHEL. It offers a free tool to switch boxes' package source, but RHEL 7 hits what Red Hat terms "the end of its maintenance support 2 phase" on the same day. RHEL 7 isn't EOL, but you'll need to pay extra for "Extended Lifecycle Support (ELS)" to keep security fixes coming. Lansweeper seems confident this will happen: "Assuming most of the CentOS devices will migrate over to RHEL, we can expect RHEL to comfortably take over first place from Ubuntu soon." RHEL was already on 20% of the machines scanned by Lansweeper (with Rocky Linux at 1.5%). But the Register argues that instead of switching to RHEL, "the freeloaders running CentOS Linux might well migrate to one of the RHELatives instead. CIQ publishes guidance on how to migrate to Rocky Linux, and will help if you buy its CIQ Bridge service. AlmaLinux has more than that with its ELevate tool to perform in-place version upgrades, as we described back in 2022. "Or, of course, you could just reinstall with Debian, and run anything you can't immediately reprovision in a free RHEL container image."

CNN reports that the low-calorie sweetener xylitol used "may be linked to nearly twice the risk of heart attacks, stroke and death in people who consume the highest levels of the sweetener, a new study found..." In 2023, the same researchers found similar results for another low-calorie sweetener called erythritol, which is used as a bulking sugar in stevia, monkfruit and keto reduced-sugar products. Additional lab and animal research presented in both papers revealed erythritol and xylitol may cause blood platelets to clot more readily. Clots can break off and travel to the heart, triggering a heart attack, or to the brain, triggering a stroke. In the new study on xylitol, "differences in platelet behavior were seen even after a person consumed a modest quantity of xylitol in a drink typical of a portion consumed in real life," said Dr. Matthew Tomey, a cardiologist at Mount Sinai Fuster Heart Hospital in New York City, who was not involved in the study... "Through their work, the investigators have shined a light on the safety of sugar substitutes. There is more to learn," Mount Sinai's Tomey said. "In the meantime, it is worth remembering that sugar substitutes are no substitute for a sincere commitment to the several elements of a healthy diet and lifestyle." Tomey added that the experiments "are interesting but alone do not prove that platelet abnormalities are to account for a linkage between xylitol and clinical events." But CNN notes that the researchers began by analyzing over 3,200 blood samples — and then also gave volunteers a typical xylitol-sweetened drink to see how much in increased their glucose levels. "They went up 1,000-fold," senior study author Dr. Stanley Hazen told CNN. His study adds that the World Health Organization warned consumers in 2023 to avoid artificial sweeteners for weight loss and called for additional research on the long-term toxicity of low- and no-calorie sweeteners.

An anonymous reader shared this report from the Washington Post: A YouTuber who posted a Fourth of July video in which passengers on a low-flying helicopter shot fireworks at a speeding Lamborghini is facing a federal charge tied to the stunt. Suk Min Choi, 24, who runs a YouTube channel under the name Alex Choi, was charged Thursday with causing the placement of an explosive or incendiary device on an aircraft, the Justice Department announced. He arranged to have the helicopter fly over the El Mirage Dry Lakebed near Los Angeles in June 2023 for a video titled "Destroying a Lamborghini With Fireworks," according to a complaint filed in the Central District Court of California. The video, released on July 4, shows scenes akin to an action film as Choi laughs while driving the Lamborghini and helicopter-launched fireworks ricochet off the car, enveloping it in sparks... Choi faces up to 10 years in prison if convicted, according to the Justice Department. More details from NBC Los Angeles: Federal authorities said radar data from the day of the video shoot showed that the helicopter left an airport in Pacoima, California, around 1:53 p.m. and turned toward El Mirage Lake, a dry lake in California, where the video was filmed. The helicopter's transponder was then turned off, according to the affidavit. The helicopter reappeared on the radar and flew back to the airport just before 9 p.m., the document says. The pilot initially told an FAA inspector that he did not know anything about the El Mirage video, according to the affidavit. In a follow-up call, he told inspectors that he did not want Choi to know he was speaking with them and said "Choi was doing unsafe activities involving cars and aircraft." In January, the FAA issued an emergency order revoking the pilot's private pilot certification, the affidavit says.

America "is now adding less wind capacity each year" than it was before the passage of a climate-protecting bill in 2022, according to the New York Times. Since then "solar panel installations are indeed soaring to record highs in the U.S., as are batteries that can store energy for later. But wind power has struggled, both on land and in the ocean." Some factors behind the wind industry's recent slowdown may be temporary, such as snarled supply chains. But wind power is also more vulnerable than solar power to many of the biggest logistical hurdles that hinder energy projects today: a lack of transmission lines, a lengthy permitting process and a growing backlash against new projects in many communities... [M]any areas are now crowded with turbines and existing electric grids are clogged, making it difficult to add more projects. Energy companies want to expand the grid's capacity to transport even more wind power to population centers, but getting permits for transmission lines and building them has become a brutal slog that can take more than a decade... Because they can reach the height of skyscrapers, wind turbines are more noticeable than solar farms and often attract more intense opposition from local communities. The wind industry has also been hampered by soaring equipment costs after the pandemic wrecked supply chains and inflation spiked. While those factors initially hurt solar, too, the solar industry has adjusted much faster, with China nearly doubling its manufacturing capacity for panels over the past two years. Wind supply chains, which are dominated by a few manufacturers in China, Europe and the United States, have yet to fully recover. The cost increases have been devastating for offshore wind projects in the Northeast, where developers have canceled more than half the projects they planned to build this decade. Wind isn't languishing only in the United States. While a record 117 gigawatts of new wind capacity came online last year globally, virtually all of that growth was in China. In the rest of the world, developers weren't installing wind turbines any faster than they were in 2020... It's still possible that wind power could rebound. In fact, some experts argue that the recent slowdown is only a temporary artifact of tax policy... [John Hensley, vice president for markets and policy analysis at the American Clean Power Association, a renewable industry trade group] said that U.S. wind manufacturing was beginning to ramp up thanks to new tax incentives, while costs were starting to come down. Last year, orders for new turbines increased by 130%, although many of them won't be delivered until 2025 or later. Some states are now trying to make it easier to build renewable energy: Illinois, Michigan and Minnesota have all passed laws making it harder for local governments to restrict wind and solar. The federal government has issued new rules to accelerate the planning of transmission lines. Demand for wind could also rise as a growing number of states, tech companies and hydrogen producers are trying to secure clean electricity around the clock, rather than just a burst of solar power in the daytime. Many plans for moving America off fossil fuels "envision a large expansion of both solar and wind," the article points out, "because the two sources generate electricity at different hours and can complement each other. A boom in solar power alone, which runs only in daytime, isn't enough."

HP is facing something of a challenge as the number of printed pages has decreased by 20% since the pandemic. "On the office space, clearly, the amount of pages that is being printed is lower than before the pandemic," HP boss Enrique Lores told tech investors at Bernstein's 40th Annual Strategic Decision Conference last week. "And this is really driven by what we call hybrid work. There are less people in the office every day, and this has driven the amount of pages down." The Register reports: "I use pages as a proxy because, depending on what happens with pages, happens eventually with devices. Before the pandemic, our estimates were that we were expecting to see a 20 percent reduction of printing. And actually, we were looking at the numbers ... and this is more or less where we are." In terms of users printing at home, "during the pandemic, we saw a spike of pages printed, and since then, the number of pages has been declining," Lores added. The levels are not unexpected, though, he said. The industrial customer base was "impacted during the last two or three years by a reduction of capital investments," but recovery is showing up, with those customers printing more labels and packaging. Previous research by IDC showed around 450 billion fewer pages were printed in homes and office worldwide in 2020 versus the year before the pandemic, equating to a 19 percent plunge. It merely accelerated the long-term trend. [...]

Carbon dioxide levels in Earth's atmosphere are accumulating "faster than ever" and have reached unprecedented levels, with a peak of 426.9 ppm recorded at NOAA's Mauna Loa Observatory in May 2024, said scientists from NOAA, the Scripps Institution of Oceanography and the University of California San Diego. CBS News reports: "Over the past year, we've experienced the hottest year on record, the hottest ocean temperatures on record, and a seemingly endless string of heat waves, droughts, floods, wildfires and storms," NOAA Administrator Rick Spinrad said in a press release. "Now we are finding that atmospheric CO2 levels are increasing faster than ever." The researchers measured carbon dioxide, or CO2, levels at the Mauna Loa Atmospheric Baseline Observatory. They found that atmospheric levels of the gas hit a seasonal peak of just under 427 parts per million in May -- an increase of 2.9 ppm since May 2023 and the fifth-largest annual growth in 50 years of data recording. It also made official that the past two years saw the largest jump in the May peak -- when CO2 levels are at their highest in the Northern Hemisphere. John Miller, a NOAA carbon cycle scientist, said that the jump likely stems from the continuous rampant burning of fossil fuels as well as El Nino conditions making the planet's ability to absorb CO2 more difficult. The surge of carbon dioxide levels at the measuring station surpassed even the global average set last year, which was a record high of 419.3 ppm -- 50% higher than it was before the Industrial Revolution. However, NOAA noted that their observations were taken at the observatory specifically, and do not "capture the changes of CO2 across the globe," although global measurements have proven consistent without those at Mauna Loa. "Not only is CO2 now at the highest level in millions of years, it is also rising faster than ever," Ralph Keeling, director of Scripps' CO2 program, said in the release. "Each year achieves a higher maximum due to fossil-fuel burning, which releases pollution in the form of carbon dioxide into the atmosphere. Fossil fuel pollution just keeps building up, much like trash in a landfill." "We are living in unprecedented times. ... This string of hottest months will be remembered as comparatively cold," Carlo Buontempo, director of Copernicus, added.

An anonymous reader quotes a report from Science Magazine: Authors of a landmark Alzheimer's disease research paper published in Nature in 2006 have agreed to retract the study in response to allegations of image manipulation. University of Minnesota (UMN) Twin Cities neuroscientist Karen Ashe, the paper's senior author, acknowledged in a post on the journal discussion site PubPeer that the paper contains doctored images. The study has been cited nearly 2500 times, and would be the most cited paper ever to be retracted, according to Retraction Watch data. "Although I had no knowledge of any image manipulations in the published paper until it was brought to my attention two years ago," Ashe wrote on PubPeer, "it is clear that several of the figures in Lesne et al. (2006) have been manipulated ... for which I as the senior and corresponding author take ultimate responsibility." After initially arguing the paper's problems could be addressed with a correction, Ashe said in another post last week that all of the authors had agreed to a retraction -- with the exception of its first author, UMN neuro-scientist Sylvain Lesne, a protege of Ashe's who was the focus of a 2022 investigation by Science. "It's unfortunate that it has taken 2 years to make the decision to retract," says Donna Wilcock, an Indiana University neuroscientist and editor of the journal Alzheimer's & Dementia. "The evidence of manipulation was overwhelming." The 2006 paper suggested an amyloid beta (AB) protein called AB*56 could cause Alzheimer's. AB proteins have long been linked to the disease. The authors reported that AB*56 was present in mice genetically engineered to develop an Alzheimer's-like condition, and that it built up in step with their cognitive decline. The team also reported memory deficits in rats injected with AB*56. For years researchers had tried to improve Alzheimer's outcomes by stripping amyloid proteins from the brain, but the experimental drugs all failed. AB*56 seemed to offer a more specific and promising therapeutic target, and many embraced the finding. Funding for related work rose sharply. But the Science investigation revealed evidence that the Nature paper and numerous others co-authored by Lesne, some listing Ashe as senior author, appeared to use manipulated data. After the story was published, leading scientists who had cited the paper to support their own experiments questioned whether AB*56 could be reliably detected and purified as described by Lesne and Ashe -- or even existed. Some said the problems in that paper and others supported fresh doubts about the dominant hypothesis that amyloid drives Alzheimer's. Others maintained that the hypothesis remains viable. That debate has continued amid the approval of the antiamyloid drug Leqembi, which modestly slows cognitive decline but carries risks of serious or even fatal brain swelling or bleeding.

Michelle Lewis reports via Electrek: The world's largest solar farm, in the desert in northwestern Xinjiang, is now connected to China's grid. The 3.5-gigawatt (GW), 33,000-acre solar farm is outside Urumqi, Xinjiang's capital. The state asset regulator's website cited the Power Construction Corp of China and said it came online on Monday. The solar farm will generate about 6.09 billion kilowatt hours (kWh) of electricity annually. Assuming an EV consumes about 3,000 kWh per year, 6.09 billion kWh could power 2.03 million EVs annually. The world's largest solar farm in Xinjiang is part of China's megabase project, a plan to install 455 GW of wind and solar. The megabase projects are sited in sparsely populated, resource-rich areas and send their generated energy to major urban centers, such as on China's eastern seaboard. China now boasts the three largest solar farms in the world by capacity. The Ningxia Tenggeli and Golmud Wutumeiren solar farms, each with a capacity of 3 MW, are already online.

As reported by Jon Peddie Research, Nvidia now holds 88% of the GPU market after its market share jumped 8% in its most recent quarter. "This jump shaves 7% off of AMD's share, putting it down to 19% total," reports XDA Developers. "And if you're wondering where that extra 1% went, it came from all of Intel's market share, squashing it down to 0%." From the report: Dr. Jon Peddie, president of Jon Peddie Research, mentions how the GPU market hasn't really looked "normal" since the 2007 recession. Ever since then, everything from the crypto boom to COVID has messed with the usual patterns. Usually, the first quarter of a year shows a bit of a dip in GPU sales, but because of AI's influence, it may seem like that previous norm may be forever gone: "Therefore, one would expect Q2'24, a traditional quarter, to also be down. But, all the vendors are predicting a growth quarter, mostly driven by AI training systems in hyperscalers. Whereas AI trainers use a GPU, the demand for them can steal parts from the gaming segment. So, for Q2, we expect to see a flat to low gaming AIB result and another increase in AI trainer GPU shipments. The new normality is no normality."

Bruce66423 shares a report from The Independent: A potential disaster was narrowly avoided when a packed passenger plane took off just seconds before it was about to run out of runway because of a software glitch. The Boeing aircraft, operated by TUI, departed from Bristol Airport for Las Palmas, Gran Canaria on 9 March with 163 passengers on board when it struggled to take off. The 737-800 plane cleared runway nine with just 260 metres (853ft) of tarmac to spare at a height of 10ft. It then flew over the nearby A38 road at a height of just 30 metres (100ft) travelling at the speed of around 150kts (about 173mph). The A38 is a major A-class busy road, connecting South West England with the Midlands and the north. The Air Accidents Investigation Branch (AAIB), part of the Department for Transport, said the incident was the result of insufficient thrust being used during take-off. Pilots manually set the thrust level following a software glitch that Beoing was aware of before take-off. "A Boeing 737-800 completed a takeoff from Runway 09 at Bristol Airport with insufficient thrust to meet regulated performance," the AAIB report said. "The autothrottle (A/T) disengaged when the takeoff mode was selected, at the start of the takeoff roll, and subsequently the thrust manually set by the crew (84.5% N1 ) was less than the required takeoff thrust (92.8% N1 ). Neither pilot then noticed that the thrust was set incorrectly, and it was not picked up through the standard operating procedures (SOPs)."
