'Why the World Needs Lazier Robots' (msn.com) 16

"Robots and AI models share one crucial characteristic," writes the Washington Post. "Whether to move around, conduct conversations or solve problems, they function by constantly taking in and computing increasingly vast quantities of data. It's a brute-force approach to automation. Processing all that data makes them such energy guzzlers that their planet-warming pollution could outweigh any benefits they offer."

But then the article visits the robot soccer team of René van de Molengraft (chair of robotics at Eindhoven University of Technology in the Netherlands). "One solution, Molengraft thinks, might lie in 'lazy robotics,' a cheeky term to describe machines doing less and taking shortcuts..." There may be ceilings for laziness: limits to how much superfluous energy use can be stripped away before robots stop functioning as they should. Still, Molengraft said, "The truth is: Robots are still doing a lot of things that they shouldn't be doing." To waste less energy, robots need to do less of everything: move less, and think less, and sense less. They need to focus only on what's important at any particular moment. Which, after all, is what humans do, even if we don't always realize it....

Lazy robotics is already percolating out of university labs and into the R&D wings of corporations.... On the outskirts of Eindhoven, engineers at health technology firm Philips have encoded lazy robotics into two porcelain-white machines. These robots, named FlexArm and Biplane, move around an operating theater with smooth hums, taking X-ray images to help surgeons install cardiac stents or work on the brain with greater precision.... The robots use proximity sensors, which use far less energy. Lazy robotics can also cut down on the number of X-rays during a procedure. Frequently, surgeons take multiple X-rays to make their work as precise as possible. But with the robots' help, they can track the exact coordinates on a patient's body they are operating on in real time...

The theories behind lazy robotics make robots smart in a more practical way: by coding in an awareness of what they don't need to know. It may be a while before these solutions are deployed at scale out in the world, but their potential applications are already evident... Molengraft sees an extension of lazy robotics into the realm of generative AI, in which machines don't learn how to move but learn how to learn by processing veritable oceans of data... It's wiser to build versions that contain only the necessary information. A language model used by software engineers, for instance, shouldn't need to run through its training data about world history, sporting records or children's literature. "Not every AI model has to be able to tell us about the first Harry Potter book," Molengraft said.

The less data an AI model crunches, the less energy it uses — a vital efficiency fillip given that ChatGPT now uses 500,000 kilowatt-hours of energy a day, responding to 200 million queries. A U.S. household would need more than 17,000 days on average to rack up the same electricity bill... Molengraft sees this work as indispensable if the forthcoming age of machines is to be a cleaner time as well.

Constellation Inks $1 Billion Deal To Supply US Government With Nuclear Power (reuters.com) 59

An anonymous reader quotes a report from Reuters: Constellation Energy has been awarded a record $1 billion in contracts to supply nuclear power to the U.S. government over the next decade, the company said on Thursday. Constellation, the country's largest operator of nuclear power plants, will deliver electricity to more than 13 federal agencies as part of the agreements with the U.S. General Services Administration. The deal is the biggest energy purchase in the history of the GSA, which constructs and manages federal buildings, and is among the first major climate-focused energy agreement by the U.S. government to include electricity generated from existing nuclear reactors.

The GSA estimated that the contracts, set to begin on April 25, will comprise over 10 million megawatt-hours over 10 years and provide electricity equivalent to powering more than 1 million homes annually. The procurement will deliver electricity to 80 federal facilities located throughout the PJM Interconnection, a regional transmission operator with service covering more than 65 million people. The U.S. Department of Transportation, the Federal Reserve Board of Governors and the Army Corps of Engineers are some of the facilities that will receive the power. [...] Constellation said the deal will enable it to extend the licenses of existing nuclear plants and invest in new equipment and technology that will increase output by about 135 megawatts.
"The investments we make as a result of this contract will keep these plants operating reliably for decades to come and put new, clean nuclear energy on the grid while making the best use of taxpayer dollars," Constellation CEO Joe Dominguez said in a release.

Samsung Is the Next Company To Try To Popularize 3D Displays (Again) (arstechnica.com) 82

Samsung is set to debut its new Odyssey 3D monitor at CES 2025, reviving the glasses-free 3D experience that manufacturers pushed on consumers over a decade ago. While details remain limited, the monitor reportedly utilizes a lenticular lens, stereo cameras, and AI to convert 2D content into lifelike 3D visuals, with a focus on appealing to gamers for broader adoption. Ars Technica reports: According to the South Korean company's announcement, the monitor's use of a lenticular lens that is "attached to the front of the panel and its front stereo camera" means that you don't have to wear glasses to access the monitor's "customizable 3D experience." Lenticular lenses direct different images to each eye to make images look three-dimensional. This is a notable advancement from the first 3D monitor that Samsung released in 2009. That display used Nvidia software and Nvidia shutter glasses to allow users to toggle between a 2D view and a 3D view through a few button presses and supported content.

Another advancement is the Odyssey 3D's claimed ability to use artificial intelligence "to analyze and convert 2D video into 3D." We've recently seen similar technology from brands like Acer, which announced portable monitors in 2022 and then announced laptops that could convert 2D content into stereoscopic 3D in 2023. Those displays also relied on AI, as well as a specialized optical lens and a pair of eye-tracking cameras, to create the effect. But unlike Acer's portable monitors, Samsung claims that its monitor can make 2D content look like 3D even if that content doesn't officially support 3D. [...] Interestingly, Samsung's announcement today only mentioned the release of a 27-inch, 4K resolution 3D monitor, despite Samsung teasing a 37-inch version in August. It's possible that the larger version didn't work as well and/or that demand for the larger size would be too small, considering the high price and limited demand implications of a glasses-free 3D monitor aimed at gamers.

California Grid Ran On 100% Renewables For a Record 98 Days (electrek.co) 72

An anonymous reader quotes a report from Electrek: A new study published in the journal Renewable Energy (PDF) uses data from the state of California to demonstrate that no blackouts occurred when wind-water-solar electricity supply exceeded 100% of demand on the state's main grid for a record 98 of 116 days from late winter to early summer 2024 for an average (maximum) of 4.84 (10.1) hours per day. Compared to the same period in 2023, solar output in California is up 31%, wind power is up 8%, and batteries are up a staggering 105%. Batteries supplied up to 12% of nighttime demand by storing and redistributing excess solar energy.

And here's the kicker: California's high electricity prices aren't because of wind, water, and solar energy. (That issue is primarily caused (PDF) by utilities recovering the cost of wildfire mitigation, transmission and distribution investments, and net energy metering.) In fact, researchers from Stanford, Lawrence Berkeley National Laboratory, and the University of California, Berkeley found that states with higher shares of renewable energy tend to see lower electricity prices. The takeaway -- and the data backs it up -- is that a large grid dominated by wind, water, and solar is not only feasible, it's also reliable.

China To Build Thorium Molten-Salt Reactor In 2025 (ieee.org) 109

In 2025, China plans to start building a demonstration thorium-based molten-salt reactor in the Gobi Desert. IEEE Spectrum reports: The 10-megawatt reactor project, managed by the Chinese Academy of Sciences' Shanghai Institute of Applied Physics (SINAP), is scheduled to be operational by 2030, according to an environmental-impact report released by the Academy in October. The project follows a 2-MW experimental version completed in 2021 and operated since then. China's efforts put it at the forefront of both thorium-based fuel breeding and molten-salt reactors. Several companies elsewhere in the world are developing plans for this kind of fuel or reactor, but none has yet operated one. Prior to China's pilot project, the last operating molten-salt reactor was Oak Ridge National Laboratory's Molten Salt Reactor Experiment, which ran on uranium. It shut down in 1969.

Thorium-232, found in igneous rocks and heavy mineral sands, is more abundant on Earth than the commonly used isotope in nuclear fuel, uranium-235. But this weakly radioactive metal isn't directly fissile -- it can't undergo fission, the splitting of atomic nuclei that produces energy. So it must first be transformed into fissile uranium-233. That's technically feasible, but whether it's economical and practical is less clear. The attraction of thorium is that it can help achieve energy self-sufficiency by reducing dependence on uranium, particularly for countries such as India with enormous thorium reserves. But China may source it in a different way: The element is a waste product of China's huge rare earth mining industry. Harnessing it would provide a practically inexhaustible supply of fuel. Already, China's Gansu province has maritime and aerospace applications in mind for this future energy supply, according to the state-run Xinhua News Agency.

Scant technical details of China's reactor exist, and SINAP didn't respond to IEEE Spectrum's requests for information. The Chinese Academy of Sciences' environmental-impact report states that the molten-salt reactor core will be 3 meters in height and 2.8 meters in diameter. It will operate at 700 C and have a thermal output of 60 MW, along with 10 MW of electricity. [...] But many challenges come along with thorium use. A big one is dealing with the risk of proliferation. When thorium is transformed into uranium-233, it becomes directly usable in nuclear weapons. "It's of a quality comparable to separated plutonium and is thus very dangerous," says Edwin Lyman, director of nuclear power safety at the Union of Concerned Scientists in Washington, D.C. If the fuel is circulating in and out of the reactor core during operation, this movement introduces routes for the theft of uranium-233, he says.

In a First, Surgical Robots Learned Tasks By Watching Videos (msn.com) 36

Speaking of robots, Johns Hopkins University and Stanford University researchers say they trained robots to perform surgical tasks autonomously using video learning, marking a breakthrough in robotic surgery capabilities.

The robots successfully manipulated needles, tied knots, and sutured wounds independently, demonstrating ability to correct errors like dropped needles without human input. Testing has advanced to full surgeries on animal cadavers.

Researchers aim to address a projected U.S. surgeon shortage of 10,000-20,000 by 2036. The technology builds on decades of robot-assisted surgery, which recorded 876,000 procedures in 2020.

Nvidia Bets on Robotics To Drive Future Growth 13

An anonymous reader shares a report: Nvidia is betting on robotics as its next big driver of growth, as the world's most valuable semiconductor company faces increasing competition in its core AI chipmaking business. The US tech group, best known for the infrastructure that has underpinned the AI boom, is set to launch its latest generation of compact computers for humanoid robots [non-paywalled link] -- dubbed Jetson Thor -- in the first half of 2025.

Nvidia is positioning itself to be the leading platform for what the tech group believes is an imminent robotics revolution. The company sells a "full stack" solution, from the layers of software for training AI-powered robots to the chips that go into them. [...] Talla said a shift in the robotics market is being driven by two technological breakthroughs: the explosion of generative AI models and the ability to train robots on these foundational models using simulated environments. The latter has been a particularly significant development as it helps solve what roboticists call the "Sim-to-Real gap," ensuring robots trained in virtual environments can operate effectively in the real world, he said.

Russia Bans Crypto Mining in Multiple Regions, Citing Energy Concerns (engadget.com) 89

The Russian government has banned crypto mining in ten regions for a period of six years, according to reporting by the state-owned news agency Tass. Engadget adds: Russia has cited the industry's high power consumption rates as the primary reason behind the ban. Crypto is particularly power-hungry, as mining operations already account for nearly 2.5 percent of US energy use.

This ban takes effect on January 1 and lasts until March 15, 2031. The country's Council of Ministers has also stated that additional bans may be required in other regions during periods of peak energy demand. It could also go the other way. The ban could be temporarily lifted or altered in certain regions if a government commission examines changes in energy demand and deems it necessary.

South Korea Mulls Creating 'KSMC' Contract Chipmaker To Compete With TSMC (tomshardware.com) 11

An anonymous reader quotes a report from Tom's Hardware: Although Samsung Foundry is a major chip contract manufacturer, the South Korean government mulls creating a government-funded contract chipmaker tentatively called Korea Semiconductor Manufacturing Company, KSMC, reports The Korea Biz Wire. Industry experts and academics have proposed the initiative.

The Semiconductor Industry Association's Ahn Ki-hyun called for a long-term government investment. Experts project that an investment of KRW 20 trillion ($13.9 billion) in KSMC could result in economic gains of KRW 300 trillion ($208.7 billion) by 2045. However, the big question is whether $13.9 billion is enough to establish a chipmaker. Another concern about publicly funded corporations like KSMC is whether they could develop advanced manufacturing technologies and land enough orders from clients to be profitable. It turns out that in addition to semiconductor makers, Korea needs more fabless software developers.

The proposal was introduced during a seminar hosted by the National Academy of Engineering of Korea (NAEK). The plan aims to address structural weaknesses in the industry, such as an over-reliance on Samsung's advanced nodes under 10nm amid the lack of mature process technologies. Smaller system semiconductor firms struggle to thrive as Korea lacks manufacturing diversity, as seen in Taiwan, where companies like UMC and PSMC that focus on mature and specialty nodes complement TSMC's advanced process technologies.

One Third of Adults Can't Delete Device Data 50

The UK's Information Commissioner's Office (ICO) warns that while most adults recognize the importance of wiping personal data from old devices, nearly 30% don't know how, and a significant number of young people either don't care or find it too cumbersome. The Register reports: Clearing personal data off an old device is an important step before ditching it or handing it on to another user. However, almost three in ten (29 percent) of adults don't know how to remove the information, according to a survey of 2,170 members of the UK public. Seventy-one percent agreed that wiping a device was important, but almost a quarter (24 percent) reckoned it was too arduous. This means that the drawer of dusty devices is set to swell -- three-quarters of respondents reported hanging on to at least one old device, and a fifth did so because they were worried about their personal information. [...]

More than one in five (21 percent) of young people in the survey didn't think it was important to wipe personal data, while 23 percent said they didn't care about what might happen to that data. Fourteen percent of people aged 18-34 said they wouldn't bother wiping their devices at all, compared to just 4 percent of people over 55. On the plus side, the majority (84 percent) of respondents said they would ensure data was erased before disposing of a device. Alternatively, some might not worry about it and stick it in that special drawer alongside all the cables that might be needed one day. The survey also found that more than a quarter (27 percent) of UK adults were planning to treat themselves to a new device over the festive season [...].

OpenAI Has Discussed Making a Humanoid Robot, Report Says (theinformation.com) 28

An anonymous reader shares a report: Over the past year, OpenAI has dropped not-so-subtle hints about its revived interest in robotics: investing in startups developing hardware and software for robots such as Figure and Physical Intelligence and rebooting its internal robotics software team, which it had disbanded four years ago.

Now, OpenAI could be taking that interest to the next level. The company has recently considered developing a humanoid robot, according to two people with direct knowledge of the discussions. As a refresher, humanoid robots typically have two arms and two legs, distinguishing them from typical robots in a warehouse or factory that might have a single arm repeatedly performing the same task on an assembly line. Developers of humanoid robots think it will be easier for them to handle tasks in the physical world -- which is tailored to humans -- than it would be to change our physical environments to suit new robots.

New Physics Sim Trains Robots 430,000 Times Faster Than Reality (arstechnica.com) 26

An anonymous reader quotes a report from Ars Technica: On Thursday, a large group of university and private industry researchers unveiled Genesis, a new open source computer simulation system that lets robots practice tasks in simulated reality 430,000 times faster than in the real world. Researchers also plan to introduce an AI agent to generate 3D physics simulations from text prompts. The accelerated simulation means a neural network for piloting robots can spend the virtual equivalent of decades learning to pick up objects, walk, or manipulate tools during just hours of real computer time.

"One hour of compute time gives a robot 10 years of training experience. That's how Neo was able to learn martial arts in a blink of an eye in the Matrix Dojo," wrote Genesis paper co-author Jim Fan on X, who says he played a "minor part" in the research. Fan has previously worked on several robotics simulation projects for Nvidia. [...] The team also announced they are working on the ability to generate what it calls "4D dynamic worlds" -- perhaps using "4D" because they can simulate a 3D world in motion over time. The system will reportedly use vision-language models (VLMs) to generate complete virtual environments from text descriptions (similar to "prompts" in other AI models), utilizing Genesis's own simulation infrastructure APIs to create the worlds.

US Targets China With Probe Into Semiconductor Industry (thehill.com) 15

The Biden administration has launched a Section 301 investigation into China's semiconductor industry, citing concerns over non-market practices, supply chain dependencies, and national security risks. The Hill reports: In a fact sheet, the White House said China "routinely engages in non-market policies and practices, as well as industrial targeting, of the semiconductor industry" that harms competition and creates "dangerous supply chain dependencies."

The Biden administration said the Office of the United States Trade Representative would launch a Section 301 investigation to examine China's targeting of semiconductor chips for dominance, an effort to see whether the practices are unfairly hurting U.S. trade and take potential action. The investigation will broadly probe Chinese nonmarket practices and policies related to semiconductors and look at how the products are incorporated into industries for defense, auto, aerospace, medical, telecommunications and power. It will also examine production of silicon carbide substrates or other wafers used as inputs for semiconductors.
The probe launches four weeks before President-elect Donald Trump takes office. "The effort could offer Trump a ready avenue to begin imposing some of the hefty 60% tariffs he has threatened on Chinese imports," notes Reuters.

"Departing President Joe Biden has already imposed a 50% U.S. tariff on Chinese semiconductors that starts on Jan. 1. His administration also has tightened export curbs on advanced artificial intelligence and memory chips and chipmaking equipment."

Xerox To Buy Printer Maker Lexmark From Chinese Owners in $1.5 Billion Deal (xerox.com) 30

Xerox has agreed to acquire printer maker Lexmark for $1.5 billion, bringing the Kentucky-based company back under U.S. ownership after seven years of Chinese control.

The deal, announced Monday, will be financed through cash and debt, creating a vertically integrated printing equipment manufacturer and service provider. Lexmark, formed from IBM in 1991, was previously acquired by Chinese investors including Ninestar for $2.54 billion in 2016. The merger comes as Xerox faces declining equipment sales and a 50% year-to-date stock drop, with its market value at just over $1 billion.

France Adds First New Nuclear Reactor to Its Grid Since 1999 (yahoo.com) 94

Saturday France connected a new nuclear reactor to its grid "for the first time in a quarter century..." reports Bloomberg, "adding low-carbon electricity supply at a time when a sputtering economy has made demand sluggish." The Flamanville-3 reactor — the first such addition since Civaux 2 was connected in 1999 — will join EDF's fleet of 56 reactors in France, which generate more than two-thirds of the country's electricity and are the backbone of western Europe's power system. When fully ramped up, the new unit will provide a stable source of supply, which can be particularly useful during peak hours in the winter. Increased nuclear output will also curb the use of gas-fired power stations.

France is set for record power exports in 2024 as local demand remains subdued and it keeps adding renewable capacity. Better generation from EDF's nuclear fleet is also helping keep a lid on wholesale prices, partly reversing bill increases caused by Europe's energy crisis. The Flamanville-3 reactor in the country's northwest adds 1.6 gigawatts of output, raising France overall atomic capacity to about 63 gigawatts...

Since construction started in 2007, its budget — excluding finance costs — has quadrupled to an estimated €13.2 billion ($13.9 billion). The yearslong saga has created lasting doubts about the French nuclear industry's ability to build reactors on time and on schedule — a crucial issue as it prepares to build at least six large plants in the country. EDF's ongoing work on two similar reactors in the UK has also suffered repeated delays and cost overruns, complicating the British government's effort to raise funds for the construction of another pair of EPRs.

Energy Prices Drop Below Zero In UK Thanks To Record Wind-Generated Electricity (ecowatch.com) 135

Long-time Slashdot AmiMoJo quotes this report from EcoWatch: Record wind-generated electricity across Northern Ireland and Scotland Tuesday night pushed Britain's power prices below zero.

Wind output peaked at a record high 22.4 gigawatts (GW), breaking the previous high set [last] Sunday evening, the national system operator said, as Bloomberg reported. The record output provided more than 68 percent of the country's power.

From 5:30 to 6:30 a.m. on Wednesday, the half-hourly price fell to 6.57 pounds per megawatt-hour, according to data from European power exchange Epex Spot.

"Setting another clean electricity generation record just four days after the previous high shows the pivotal role wind is playing in keeping the country powered up during the festive season," said Dan McGrail, chief executive of RenewableUK, as . "This is also demonstrated by today's official figures which reveal that renewables have generated more than half our electricity for four quarters in a row."

The article adds that energy prices with negative numbers "have been recorded for 131 hours in the UK this year, an increase of 45 hours over 2023...

"Wind power was the largest source of energy in the UK from January to September of 2024."

Scientists Build a Nuclear-Diamond Battery That Could Power Devices for Thousands of Years (livescience.com) 89

The world's first nuclear-powered battery — a diamond with an embedded radioactive isotope — could power small devices for thousands of years, according to scientists at the UK's University of Bristol.

Long-time Slashdot reader fahrbot-bot shared this report from LiveScience: The diamond battery harvests fast-moving electrons excited by radiation, similar to how solar power uses photovoltaic cells to convert photons into electricity, the scientists said.

Scientists from the same university first demonstrated a prototype diamond battery — which used nickel-63 as the radioactive source — in 2017. In the new project, the team developed a battery made of carbon-14 radioactive isotopes embedded in manufactured diamonds. The researchers chose carbon-14 as the source material because it emits short-range radiation, which is quickly absorbed by any solid material — meaning there are no concerns about harm from the radiation. Although carbon-14 would be dangerous to ingest or touch with bare hands, the diamond that holds it prevents any short-range radiation from escaping. "Diamond is the hardest substance known to man; there is literally nothing we could use that could offer more protection," Neil Fox, a professor of materials for energy at the University of Bristol, said in the statement...

A single nuclear-diamond battery containing 0.04 ounce (1 gram) of carbon-14 could deliver 15 joules of electricity per day. For comparison, a standard alkaline AA battery, which weighs about 0.7 ounces (20 grams), has an energy-storage rating of 700 joules per gram. It delivers more power than the nuclear-diamond battery would in the short term, but it would be exhausted within 24 hours. By contrast, the half-life of carbon-14 is 5,730 years, which means the battery would take that long to be depleted to 50% power....

[A] spacecraft powered by a carbon-14 diamond battery would reach Alpha Centauri — our nearest stellar neighbor, which is about 4.4 light-years from Earth — long before its power were significantly depleted.

The battery has no moving parts, according to the article. It "requires no maintenance, nor does it have any carbon emissions."

Luigi Mangione's Ghost Gun Was Only Partially 3D-Printed (rollingstone.com) 199

"More than a decade after the advent of the 3D-printed gun as an icon of libertarianism and a gun control nightmare, police say one of those homemade plastic weapons has now been found in the hands of perhaps the world's most high-profile alleged killer," Wired wrote this month: For the community of DIY gunsmiths who have spent years honing those printable firearm models, in fact, the handgun police claim Luigi Mangione used to fatally shoot UnitedHealthcare CEO Brian Thompson is as recognizable as the now-famous alleged shooter himself — and shows just how practical and lethal those weapons have become. In the 24 hours since police released a photo of what they say is Mangione's gun following the 26-year-old's arrest Monday, the online community devoted to 3D-printed firearms has been quick to identify the suspected murder weapon as a particular model of printable "ghost gun" — a homemade weapon with no serial number, created by assembling a mix of commercial and DIY parts. The gun appears to be a Chairmanwon V1, a tweak of a popular partially 3D-printed Glock-style design known as the FMDA 19.2 — an acronym that stands for the libertarian slogan "Free Men Don't Ask."

The FMDA 19.2, released in 2021, is a relatively old model by 3D-printed-gun standards, says one gunsmith who goes by the first name John and the online handle Mr. Snow Makes... Despite its simple description by law enforcement and others as a "3D-printed pistol," the FMDA 19.2 is only partially 3D printed. That makes it fundamentally different from fully 3D-printed guns like the "Liberator," the original one-shot, 3D-printed pistol Wilson debuted in 2013. Instead, firearms built from designs like the FMDA 19.2 are assembled from a combination of commercially produced parts like barrels, slides, and magazines — sometimes sold in kits — and a homemade frame. Because that frame, often referred to as a "lower receiver" or "lower," is the regulated body of the gun, 3D-printing that piece or otherwise creating it at home allows DIY gunmakers to skirt gun-control laws and build ghost guns with no serial number, obtained with no background check or waiting period.

Chairmanwon "instantly recognized the gun seized from the suspect..." reported USA Today. As a photo circulated online the fake New Jersey driver's license and 3D-printed gun police found on Luigi Mangione, he spotted the tell-tale stippling pattern on the firearm's grip. "It's mine lol," the man, known as "Chairmanwon" quipped on X Dec. 9. Then he quickly deleted the post...

No federal laws ban 3D-printed or privately made firearms. But as police agencies have increasingly recovered untraceable homemade guns at crime scenes, some state legislatures have passed stricter rules... If authorities can prove Mangione downloaded and printed his firearm in Pennsylvania or New York, he could face additional gun charges. Fifteen states now require serial numbers on homemade parts or ban 3D printing them. Some even ban the distribution of 3D printing instructions.

President Biden and the Bureau of Alcohol, Tobacco, Firearms and Explosives added regulations in 2022 that say the ghost gun parts kits themselves qualify as "firearms" that should be regulated by the Gun Control Act. ["Commercial manufacturers of the kits will have to be licensed and must add serial numbers on the kits' frame or receiver," USA Today reported earlier. ] Gunmakers challenged those rules at the Supreme Court. In October, the court heard oral arguments, but justices signaled they were leaning toward upholding the rules.

Rolling Stone tries to assess the results: In recent years, crimes involving ghost guns seem to have abated across much of the United States. Ghost gun recoveries by police in New York City, Los Angeles, Philadelphia, Baltimore, and other major cities dropped by as much as 25 percent between 2022 and 2023, and the most prolific maker of the kits used to build the untraceable weapons closed its doors this year. The likely cause is a federal rule change requiring the kits to be serialized — a stipulation that forces sellers to conduct background checks on their customers.
Monday Luigi Mangione will appear in court for arraignment on state murder charges, reports USA Today: Mangione had been expected to face arraignment on the state charges Thursday, but the proceedings were postponed after federal authorities announced they were also bringing charges, and he was whisked to a federal courthouse instead in a move that appeared to shock Mangione's defense team... Federal authorities unsealed a criminal complaint against Mangione that included four separate charges: murder using a firearm, two counts of interstate stalking and a firearms count. The death penalty was abolished in New York state, but the federal charges could bring a death sentence if Mangione is convicted. The charge of murder using a firearm carries a maximum possible sentence of death or life in prison. The other federal charges have maximum sentences of life in prison, and the firearms charge has a mandatory minimum sentence of 30 years.

Startup Set To Brick $800 Kids Robot Is Trying To Open Source It First (arstechnica.com) 35

Last week, startup Embodied announced it was closing down, and its product, an $800 robot for kids ages 5 to 10, would soon be bricked. Now, in a blog post published on Friday, CEO Paolo Pirjanian shared that Embodied's technical team is working on a way to open-source the robot, ensuring it can continue operating indefinitely. Ars Technica reports: The notice says that after releasing OpenMoxie, Embodied plans to release "all necessary code and documentation" for developers and users. Pirjanian said that an over-the-air (OTA) update is now available for download that will allow previously purchased Moxies to support OpenMoxie. The executive noted that Embodied is still "seeking long-term answers" but claimed that the update is a "vital first step" to "keep the door open" for the robot's continued functionality.

At this time, OpenMoxie isn't available and doesn't have a release date. Embodied's wording also seems careful to leave an opening for OpenMoxie to not actually release; although, the company seems optimistic. However, there's also a risk of users failing to update their robots in time and properly. Embodied noted that it won't be able to support users who have trouble with the update or with OpenMoxie post-release. Updating the robot includes connecting to Wi-Fi and leaving it on for at least an hour. "It is extremely important that you update your Moxie with this OTA as soon as possible because once the cloud servers stop working you will not be able to update your robot," the document reads. Embodied hasn't said when exactly its cloud servers still stop working.
