"Last week Taiwan Semiconductor Manufacturing Company, the world's largest chipmaker, which supplies chips to Apple, pledged to reach net zero emissions by 2050," reports the Guardian.

"But decarbonizing the industry will be a big challenge." TSMC alone uses almost 5% of all Taiwan's electricity, according to figures from Greenpeace, predicted to rise to 7.2% in 2022, and it used about 63m tons of water in 2019. The company's water use became a controversial topic during Taiwan's drought this year, the country's worst in a half century, which pitted chipmakers against farmers. In the US, a single fab, Intel's 700-acre campus in Ocotillo, Arizona, produced nearly 15,000 tons of waste in the first three months of this year, about 60% of it hazardous. It also consumed 927m gallons of fresh water, enough to fill about 1,400 Olympic swimming pools, and used 561m kilowatt-hours of energy. Chip manufacturing, rather than energy consumption or hardware use, "accounts for most of the carbon output" from electronics devices, the Harvard researcher Udit Gupta and co-authors wrote in a 2020 paper....

[A]mid pressure from investors and electronics makers keen to report greener supply chains to customers, the semiconductor business has been ramping up action on tackling its climate footprint... Greater availability of renewable energy is helping chipmakers reduce their carbon footprint. Intel made a commitment to source 100% of its energy from renewable sources by 2030, as did TSMC, but with a deadline of 2050. Energy consumption accounts for 62% of TSMC's emissions, said a company spokesperson, Nina Kao. The company signed a 20-year deal last year with the Danish energy firm Ørsted, buying all the energy from a 920-megawatt offshore windfarm Ørsted is building in the Taiwan Strait. The deal, which has been described as the world's largest corporate renewables purchase agreement, has benefits for TSMC, said Shashi Barla, renewables analyst at the energy consultancy Wood Mackenzie. As well as guaranteeing a clean electricity supply, it pays a wholesale cost and removes itself from price shocks, "killing two birds with one stone", he said.

TSMC's actions have the potential to influence the rest of the industry, said Clifton Fonstad, professor of electrical engineering and computer science at MIT, "other manufacturers are likely to follow its lead"...

There is also innovation aimed at tackling the worst-polluting materials used in making semiconductors. The chip industry uses different gases during the production process, many of which have a significant climate impact. TSMC said it had implemented scrubbers and other facilities to treat gas emissions. But another route is replacing "dirtier" cleaning gases that clean the delicate tools in semiconductor manufacturing, said Michael Pittroff, a chemical engineer working on semiconductor gases at Solvay Special Chemicals. In industrial tests over the last six years with about a half dozen chipmaker clients, Pittroff said, he and his team had replaced more polluting gases with "cleaner" fluorine, with a lower global warming impact. Other companies target the gases that are used to etch patterns onto and clean the silicon surface of a wafer — the thin piece of material used to make semiconductors. Paris-based industrial gases company Air Liquide, for example, has come up with a line of alternative etching gases with lower global warming impacts...

Some experts believe chipmakers will start to modify their processes to incorporate greener gases, especially if the big players make a move. "If TSMC switches, I am sure the others will," said Fonstad. "If TSMC doesn't, then other manufacturers may switch to show they are better than TSMC."

CNET's Roadshow reports that a safety-oriented version of Boston Dynamics' headless dog-shaped robot "Spot" will begin patrolling a Kia plant in South Korea, "to survey industrial areas remotely and help identify issues before they happen." For example, Spot's new thermal camera and 3D lidar (courtesy of Hyundai's technology chest) can identify personnel near machinery with high temperatures. In this case, our robotic canine friend may be able to pinpoint a fire hazard before a human does. The robot can be controlled remotely by human operators as well, and send potential alarms for hazards and notify plant management of a situation. Hyundai also plans to have the robot accompany night patrols to create a safer environment. With new gadgetry attached to Spot, including the latest artificial intelligence that helps it understand if doors are open or closed, the automaker believes the robot can play a big part in security...

All of Spot's new tasks are part of a pilot program so Hyundai can see if there's value in deploying additional Spot-based, robotic security dogs in other plants.
Hyundai's motor group has released a slick video showing the security robot in action.

It ends with the words "Robotics for Humanity."

An anonymous reader quotes a report from UPI: According to a new study, published Friday in the journal Patterns, information and communications technology, or ICT for short, is responsible for a greater share of greenhouse gas emissions than previously estimated.

When researchers at Lancaster University analyzed earlier attempts to calculate ICT's carbon footprint, they determined scientists had failed to account for the entire life-cycle and supply chain of ICT products and infrastructure.

This would include, for example, the emissions produced by makers of ICT components, or the emissions linked with the disposal of ICT products.

Scientists have previously pegged ICT's share of greenhouse gas emissions at between 1.8% and 2.8%. But the latest findings suggest global computing is more likely responsible for between 2.1% and 3.9% of greenhouse gas emissions.

If the latest estimates are accurate, ICT would have a larger carbon footprint than the aviation industry, which is responsible for 2 percent of greenhouse gas emissions.

Slashdot reader oumuamua writes that two U.S. nuclear plants owned by Exelon "were almost shutdown prematurely...but were saved at the last minute by the Illinois Senate." The Illinois Senate has approved a clean energy deal which includes a subsidy for Exelon to keep the Byron nuclear plant in operation, after the House passed it last week.

The plan gives Exelon $694 million to keep the Byron and Dresden plants operational. Exelon had previously begun drawing down the Byron plant with an anticipated retirement date of Monday, September 13th, and had warned that once the nuclear fuel had been depleted, it could not be refueled after that date.

Exelon said Monday that with the passage of the bill, it was preparing to refuel both plants.
The company had actually intended to close the Byron plant for some time, according to an earlier article: In February of 2019, a filing with the U.S. Securities and Exchange Commission, Exelon said the plant is "showing increased signs of economic distress, which could lead to an early retirement, in a market that does not currently compensate them for their unique contribution to grid resiliency and their ability to produce large amounts of energy without carbon and air pollution." Exelon cited revenue shortfalls in the hundreds of millions of dollars because of declining energy prices and energy rules that allow fossil fuel plants to make cheaper bids at energy auction.
Or, as another article puts it, "Exelon says its Byron and Dresden stations are losing money."

oumuamua adds that "With the urgency of the climate crisis more clear than ever, no nuclear plant should be closed prematurely while coal plants continue operation in the same state. Many celebrated the Senate move, however, others have criticized Exelon's actions. "Exelon first started what we've dubbed the nuclear hostage crisis. It's a pattern where a utility will for whatever reasons threaten closure, which gets the workers very upset, then the local community whose tax base depends on it gets upset, they pressure their legislators, and then the legislators grant bailouts," said Dave Kraft, head of the Nuclear Energy Information Service.

Kraft said rather than continuing to support nuclear energy, Illinois needs to redouble its commitment to wind and solar.

General Motors urged some owners of Chevrolet Bolt electric cars to park and store the vehicles at least 50 feet away from other cars to reduce the risk that a spontaneous fire could spread. Bloomberg reports: The Detroit automaker has recalled all of the roughly 142,000 Bolts sold since 2016 because the battery can catch on fire. GM has taken a $1.8 billion charge so far for the cost of the recall and has been buying cars back from some disgruntled owners. The company expects to recoup much of the cost from battery supplier LG Corp. The new advice is likely to rankle owners who are already limiting their use of the Bolt to avoid overheating the battery and risking a fire. The parking guidance -- recommending a distance of 50 feet from other parked cars -- is especially difficult for owners in urban areas. GM has confirmed 10 fires. The National Highway Traffic Safety Administration said the agency has found 13 fires in Bolts, but the company hasn't confirmed the additional three are part of the current recall issue.

The Bolt normally can go 259 miles on a charge, but that has been limited by GM's guidance to avoid a fire. The automaker told Bolt owners to limit the charge to 90%, plug in more frequently and avoid depleting the battery to below about 70 miles of remaining range. They're also advised to park their vehicles outside immediately after charging and not leave them charging indoors overnight. The company will be telling Bolt owners who are concerned about parking in public places that it recommends keeping 50 feet from other cars in garages and lots, spokesman Dan Flores said.

The International Thermonuclear Experimental Reactor (ITER) currently under construction in Cadarache, southern France, will see cost overruns and delays due to the disruption caused by the COVID-19 pandemic, its top official said on Friday. Euractiv reports: When the ITER project was launched in 2015, the schedule was to have the first plasma by the end of 2025 and full nuclear fusion by 2035, said Bernard Bigot, the director general of ITER. "We were on track until the end of 2019 but unfortunately, as you know, the world has been impacted by COVID-19," Bigot told journalists during an online press conference on Friday (17 September). As a result of the pandemic, factories were stopped and ships that took on average 45 days to deliver components from Korea took 90 days to arrive, he indicated. "While we were progressing on a monthly rate of nearly 0.7% on average during the last five years, last year in 2020 we were only able to achieve 0.35%," he explained. "So clearly, first plasma in 2025 is no longer technically achievable."

The delay means the costs of ITER will also likely go over budget, because of "running costs that cannot be eliminated," Bigot explained, saying he was preparing a full review for the ITER Council in November 2022. That said, Bigot expressed confidence that with the COVID-19 crisis receding, "we will be able to keep to the real target," which is to attain full fusion power by 2035. [...] The goal of the experimental plant is to demonstrate that fusion power can be generated sustainably, and safely, on a commercial scale. "Fusion provides clean, reliable energy without carbon emissions," said a statement from the 35 ITER partners.

Rolls-Royce's "Spirit of Innovation" all-electric airplane completed a 15 minute flight, marking "the beginning of an intensive flight-testing phase in which we will be collecting valuable performance data on the aircraft's electrical power and propulsion system," the company announced. Engadget reports: Rolls Royce said the one-seat airplane has "the most power-dense battery pack every assembled for an aircraft." The aircraft uses (PDF) a 6,000 cell battery pack with a three-motor powertrain that currently delivers 400kW (500-plus horsepower), and Rolls-Royce said the aircraft will eventually achieve speeds of over 300 MPH. The flight comes about a year after the originally scheduled takeoff and about six months after taxi trials. Rolls-Royce is also developing an air taxi with manufacturer Tecnam, with the aim of delivering an "all-electric passenger aircraft for the commuter market," according to the companies. It has previously teamed with Siemens and Airbus on another e-plane concept.

The project was half funded by the Aerospace Technology Institute and UK government, with the aim of eventually creating all-electric passenger planes. "This is not only about breaking a world record; the advanced battery and propulsion technology developed for this program has exciting applications for the Urban Air Mobility market and can help make 'jet zero' a reality," said Rolls-Royce CEO Warren East.

An anonymous reader quotes a report from InterestingEngineering: As global carbon emissions that stem from fossil fuels keep adding to our ever-growing climate change issue, energy companies have turned their focus on renewables to generate fuel. One of those companies is Synhelion from Switzerland. The company harnesses the energy of the heat of the sun and converts the collected carbon dioxide into synthetic fuels, in turn offering a green and sustainable solution. The system is quite genius. Synhelion uses a mirror field filled with heliostats to reflect the radiation of solar power. The radiation is then concentrated in the solar receiver and turned into clean, high-temperature process heat at around 2.732F (1.500C). Next, the produced heat is turned into a CO2 and H2O mixture in a thermochemical reactor. The end product, the syngas, is then turned into gasoline, diesel, or jet fuel with a gas-to-liquid technology process. What makes this sustainable is the fact that the company's thermal energy storage (TES) saves the excess heat after each process which keeps the operation going 24/7.

And how does the solar receiver work? The company says the technology is inspired by nature. To reach ultra-high temperatures, the solar receiver mimics Earth's greenhouse gas effect. The chamber is filled with greenhouse gases that are usually water vapor or water and CO2 mixtures. After solar radiation collected with heliostats enters the chamber, the black surface of the chamber absorbs the heat, thermalizes, and re-radiates it. The greenhouse gas then absorbs the thermal radiation, acting as a heat transfer fluid (HTF), which can, later on, be turned into any type of liquid fuel. And liquid fuels are easy to transport which makes them low-cost compared to their solid counterparts. When there's no sun, the HTF flows through the TES in the opposite direction to recover the previously stored thermal energy. The hot HTF from the storage drives the thermochemical processes in the reactor that keeps the operation working. "The company states that through this technology, it can provide fuels at a cheaper price with a 50 to 100 percent lower carbon footprint compared to fossil fuels," the report adds. "In addition to Synhelion's aligned motives with the Paris Agreement's CO2 reduction targets, it is supported by larger industries looking to cut their emissions -- and eventually achieve net-zero -- by 2030."

Razer has announced an update to its popular Huntsman lineup of mechanical keyboards that reduces input latency to "near-zero," the company claims. The Verge reports: [T]he newly announced Huntsman V2 and Huntsman V2 Tenkeyless (which omits the numpad, volume wheel, and media controls for a more compact board) both have a polling rate of 8,000Hz, meaning they can theoretically detect key presses eight times faster than the original Huntsman keyboards. Combined with the keyboards' optical switches, which use an infrared beam of light to sense when they've been pressed rather than metal contact points, Razer reckons the two new Huntsman keyboards will feel more responsive for gaming, especially when combined with a high-refresh rate monitor. In contrast, standard mechanical switches can suffer from what's known as a "debounce delay," when the keyboard has to take a moment to work out if a key has actually been pressed or not.

Other improvements introduced with the V2 keyboards include new doubleshot PBT keycaps, which have a more durable design with legends that shouldn't wear away over time. The doubleshot design also allows the keyboard's programmable RGB backlighting to shine through the caps. There are seven preset lighting effects built into the keyboard, and you can customize them via Razer's software and save them to the board's firmware. Both keyboards are available with either Razer's clicky or linear optical switches. The linear switches have also seen improvements since the keyboard's first iteration, with the addition of a silicon sound dampener inside, and more lubricant to make them feel smoother to press. Razer also says it's improved the acoustics of the keyboards, with the addition of a new layer of sound dampening foam, and there's now a wrist rest included in the box with both keyboards. The full-size Huntsman V2 features a volume wheel and media controls on its top right, but only the smaller tenkeyless model has a detachable USB-C cable.

The EPA says the Lucid Air electric sedan will do 520 miles on a full charge, which is well over 100 miles more than the Tesla Model S Long Range, which delivers an estimated 405 miles. CNET reports: The 520-mile range estimate is specific to the Air Dream Edition Range with 19-inch wheels. Buyers should know the optional 21-inch wheels drop the range to an estimated 481 miles. Still, that's damned impressive. For those who select the Air Dream Edition Performance, they won't be penalized too much with a lower range. The car still comes in at an EPA-estimated 471 miles with 19-inch wheels and 451 miles with 21-inch wheels. The trade-off is there's 1,111 horsepower on tap with the Performance, compared to only 933 hp for the Range model.

The Dream Edition cars are two limited-edition choices Lucid sold out of a while ago, but don't fret, there are other options. For now, the EPA also got its hands on the Air Grand Touring trim, which returns 516 miles of range after the feds' tests. Even if you missed out on the Dream Edition Range, losing just four miles isn't the worst thing in the world. Opt for the larger 21-inch wheels on this model and the range figure drops to 469 miles. This particular configuration also provides a no-less-substantial 800 hp. If you ask me, there's nothing anyone's compromising on here. Production of the first customer cars is meant to start later this year, with prices for the Dream Editions starting at $169,000.

AMD's CFO Devinder Kumar has commented that AMD stands ready to manufacture Arm chips if needed, noting that the company's customers want to work with AMD on Arm-based solutions. From a report: Kumar's remarks came during last week's Deutsche Bank Technology Conference, building on comments from AMD CEO Lisa Su earlier in the year that underscored the company's willingness to create custom silicon solutions for its customers, be they based on x86 or Arm architectures. Intel also intends to produce Arm and RISC-V chips, too, meaning that the rise of non-x86 architectures will be partially fueled by the stewards of the dominant x86 ecosystem. "But I'll tell you from my standpoint, when you look at compute solutions, whether it's x86 or ARM or even other areas, that is an area for our focus on investment for us," AMD CFO Devinder Kumar responded to a question about the company's view of competing Arm chips. "We know compute really well. Even ARM, as you referenced, we have a very good relationship with ARM. And we understand that our customers want to work with us with that particular product to deliver the solutions. We stand ready to go ahead and do that even though it's not x86, although we believe x86 is a dominant strength in that area."

An anonymous reader quotes a report from Ars Technica: Amazon's Kindle e-readers get new software updates regularly, and they're mostly of the nondescript, invisible "performance improvements and bug fixes" variety. But the most recent operating system update (version 5.13.7) is rolling out now, and it refreshes the device's user interface for the first time since 2016 or so. Amazon says that redesigns for the Home and Library screens, which are mostly untouched in the current Kindle update, will be coming "later this year." The software update that enables the new interface began rolling out in August, but because Kindles only install updates automatically when they're charging and connected to Wi-Fi, it will be a few weeks or months before all supported Kindles will have a chance to grab the update (mine only installed it over this past weekend).

The new update is available on most Kindles released in or after 2015, including the 7th- and 10th-generation Kindle Paperwhite, the 8th-, 9th-, and 10th-generation Kindle Oasis, and the 8th- and 10th-generation standard Kindle. Older "7th-generation" Kindle devices like 2014's Kindle Voyage don't appear to be supported. [...] The new update doesn't fix Amazon's confusing Kindle naming scheme, which groups different devices into "generations" that are numbered based roughly on when they were released, not on what generation of product they actually are; the "10th-generation" Paperwhite is actually only the fourth Paperwhite Amazon has released. But you now can head into the Device Info screen and see which Kindle you're using instead of having to guess.

Researchers have developed a technique for reconstructing whole genomes, including the human genome, on a personal computer. "This technique is about a hundred times faster than current state-of-the-art approaches and uses one-fifth the resources," reports Phys.Org. From the report: The study, published September 14 in the journal Cell Systems, allows for a more compact representation of genome data inspired by the way in which words, rather than letters, offer condensed building blocks for language models. [...] To approach genome assembly more efficiently than current techniques, which involve making pairwise comparisons between all possible pairs of reads, [researchers] turned to language models. Building from the concept of a de Bruijn graph, a simple, efficient data structure used for genome assembly, the researchers developed a minimizer-space de Bruin graph (mdBG), which uses short sequences of nucleotides called minimizers instead of single nucleotides. "Our minimizer-space de Bruijn graphs store only a small fraction of the total nucleotides, while preserving the overall genome structure, enabling them to be orders of magnitude more efficient than classical de Bruijn graphs," says [one of the researchers].

The researchers applied their method to assemble real HiFi data (which has almost perfect single-molecule read accuracy) for Drosophila melanogaster fruit flies, as well as human genome data provided by Pacific Biosciences (PacBio). When they evaluated the resulting genomes, [researchers] found that their mdBG-based software required about 33 times less time and 8 times less random-access memory (RAM) computing hardware than other genome assemblers. Their software performed genome assembly for the HiFi human data 81 times faster with 18 times less memory usage than the Peregrine assembler and 338 times faster with 19 times less memory usage than the hifiasm assembler. Next, [researchers] used their method to construct an index for a collection of 661,406 bacterial genomes, the largest collection of its kind to date. They found that the novel technique could search the entire collection for antimicrobial resistance genes in 13 minutes -- a process that took 7 hours using standard sequence alignment.

Earlier today at Apple's iPhone 13 launch event, Apple introduced the Apple Watch Series 7 with a new, more seamless design with larger 41mm and 45mm cases that include larger, brighter and more durable screens. There's also a variety of new colors to choose from. Engadget reports: The update takes advantage of the bigger displays, with more information and new watch faces like Contour, Modular Duo and World Timer. As for durability? Series 7 is the first Apple Watch with a dust resistance rating (IP6X), making it better-suited to mountain climbing or the beach. The screen itself is more crack-resistant thanks to a thicker new geometry, and you'll still get swim-friendly WR50 (that is, 50-meter) water resistance. You won't confuse this with a rugged watch, but you might not panic quite so much after a fall.

The updates aren't quite so aggressive under the hood. You can anticipate 33 percent faster charging and fall detection during workouts. Most of the updates come through watchOS 8, which now includes detection of cycling workouts, better tracking for e-bikes and help if you fall off. You'll also get a full swipe-based keyboard, support for more workouts (Pilates and Tai Chi) and respiratory rate tracking while you sleep. Apple Watch Series 7 will arrive sometime this fall starting at $399. The Apple Watch SE and Watch Series 3 will hang around at respective prices of $299 and $199, and you can expect refreshed Nike and Hermes variants for the Series 7.

An anonymous reader quotes a report from PCWorld: The latest version of Radeon Software adds an unusual (and welcome) new twist: The ability to automatically overclock your Ryzen processor if you're rocking an all-AMD gaming desktop. Yes, your GPU software can speed up your CPU now, too -- and it can do it all with a single click. [...] The addition of Ryzen auto-overclocking in Radeon Software 21.9.1 continues the theme, and might just allow you to ditch AMD's separate Ryzen Master tool if you're running a Team Red graphics card. They'll need to be newer hardware, though, as the feature currently only supports AMD's latest Ryzen 5000 CPUs and Radeon RX 6000 GPUs.

AMD's blog describes how to use the new tool: "To access this easy-to-use feature, open up Radeon Software using the hotkey 'ALT' + 'R', navigate to the 'Performance' tab found at the top of the window, and select 'Tuning' in the sub tab directly below it. If you have the latest generation of AMD Ryzen and Radeon product installed on your system, a 'Tuning Control' section should appear for your system, allowing you to select 'Auto Overclock' to increase performance on both your processor and graphics card. We also have a new tuning section for CPUs, allowing you to overclock just your CPU. When the feature is selected, the system will ask for a restart and once you are back in Windows, you will be good to go!" "Radeon Software 21.9.1 also adds official Windows 11 support and the ability for Radeon RX 5000-series GPUs to tap into Smart Access Memory," adds PCWorld. "AMD also took the time to tout FidelityFX Super Resolution's rapid uptake. The DLSS rival is now supported in 27 games, with Arkane's awesome-looking Deathloop set to launch this week with native FSR support in place."

"If you're wandering around Singapore anytime soon, take some time to wave hi to your friendly neighborhood snitch bot," writes Gizmodo: Singapore's Home Team Science and Technology Agency (HTX) will be deploying two robots named "Xavier" that the agency says use cameras with a 360-degree field of vision and analytics software to detect "undesirable social behaviors" in real time.

First reported by Business Insider, the robots are designed to detect activities such as public smoking, violation of pandemic restrictions (i.e., groups of more than five people), and illegally selling goods on the street. Other behaviors the agency said the robots can snitch on include the use of motorized vehicles or motorcycles on pedestrian walkways and "improperly parked bicycles." The Xavier robots roll around on a "patrol route pre-configured in advance by public officers," though they can deviate as necessary to avoid slamming into pedestrians or other obstacles. The plan is for the two robots to relay reports of such activity to a central police hub as well as confront violators directly with warning messages, with the first three weeks of deployment starting on Sept. 5 in Toa Payoh Central.
The three weeks are a "trial period," reports ZDNet. But they also note that the program includes "an interactive dashboard where public officers can receive real-time information from and be able to monitor and control multiple robots simultaneously."

One official said in a public statement that "The deployment of ground robots will help to augment our surveillance and enforcement resources."

ZDNet offers some context: Seeing robots being used in Singapore is not uncommon. Last year, Singapore deployed Boston Dynamics' four-legged droids, dubbed Spot, to its parks, garden, and nature reserves to remind people about social distancing. A fleet of Lightstrike robots was then rolled out at one of Singapore's general hospitals in a bid to thoroughly disinfect hospital rooms of pathogens. More recently in May, the Singapore government launched a one-year trial of using autonomous robots to facilitate on-demand food and grocery deliveries.

The New York Times reports: Scientists at the Pacific Northwest National Laboratory and the University of Maryland are working to determine whether three uranium cubes they have in their possession were produced by Germany's failed nuclear program during World War II. The answer could lead to more questions, such as whether the Nazis might have had enough uranium to create a critical reaction. And if the Nazis had been successful in building an atomic bomb, what would that have meant for the war...?

The Nazis produced 1,000 to 1,200 cubes, about half of which were confiscated by the Allied forces, said Jon Schwantes, the project's principal investigator. "The whereabouts of most all of those cubes is unknown today," Schwantes said, adding that "most likely those cubes were folded into our weapons stockpile."
Two history professors speculate in the article that the technology ultimately would not have changed outcome of the war. Kate Brown, who teaches environmental and Cold War history at MIT, argues that without planes that could fly long distances without being spotted, "the only target I can think of would be London." Brown said that while a Nazi bomb would not have had much of an impact on the war, the Nazis set the stage for the Cold War simply by trying to build one. The Soviets, who were then U.S. allies in defeating Germany, were aware that the Americans took this uranium out of the country "right out from under them," she said. "That becomes a real engine for suspicion that sets up the Cold War, almost immediately," Brown said.
The project's principle investigator tells the Times they're planning to use a process called radiochronometry to date the cubes by measuring how much their uranium has decayed.

"We do believe they are from Nazi Germany's nuclear program, but to have scientific evidence of that is really what we're attempting to do."

ABC News reports: Inspired by the New Deal-era Civilian Conservation Corps, President Joe Biden and congressional Democrats are pushing for a modern counterpart: a Civilian Climate Corps that would create hundreds of thousands of jobs building trails, restoring streams and helping prevent catastrophic wildfires. Building on Biden's oft-repeated comment that when he thinks of climate change, he thinks of jobs, the White House says the multibillion-dollar program would address both priorities as young adults find work installing solar panels, planting trees, digging irrigation ditches and boosting outdoor recreation...
Colorado Public Radio reports that there's already a new Colorado Climate Corps, funded by a $1.7 million federal grant, that will place 240 members of America's federally-funded national service program "AmeriCorps" into 55 counties across Colorado "to protect public lands and help low-income communities brace for the climate crisis."

And now supporters of the larger federal program "envision climate corps workers installing solar panels, weatherizing buildings and providing water and other supplies during heat waves and storms," reports the New York Times: A new climate corps would help address the growing threat of wildfires in Idaho, according to Jay Satz, senior director for partnerships and innovation at the Northwest Youth Corps and Idaho Conservation Corps. Mr. Satz said his group doesn't have the funding or the staff to meet that need, which includes thinning out dead trees, replanting new trees and rehabilitating land hit by fires.

The New York Times looks at "a wave of new battery technologies that could lead to novel designs in consumer electronics and help accelerate the electrification of cars and airplanes. They may even help store electricity on the power grid, lending a hand to efforts to reduce dependence on fossil fuels..."

And a longer-life battery from Sila finally made it into a consumer product — the Whoop fitness tracker, which straps around your wrist, but which can also take the form of a "sliver of electronics stitched into the fabric of clothes." Sila's chief executive and co-founder, Gene Berdichevsky, was an early Tesla employee who oversaw battery technology as the company built its first electric car. Introduced in 2008, the Tesla Roadster used a battery based on lithium-ion technology, the same battery technology that powers laptops, smartphones and other consumer devices. The popularity of Tesla, coupled with the rapid growth of the consumer electronics market, sparked a new wave of battery companies.... Congress created ARPA-E, for Advanced Research Projects Agency-Energy, to promote research and development in new energy technologies. The agency nurtured the new battery companies with funding and other support. A decade later, those efforts are beginning to bear fruit...

Sila is not exactly a battery company. It sells a new material — a silicon powder — that can significantly boost the efficiency of batteries, and plans to build them using many of the same factories and other infrastructure that produce lithium-ion batteries... Today, the company produces this silicon powder from its small facility in Alameda [near Oakland, California]. Then it sells the powder to a battery manufacturer — Sila would not identify the other company — which slots the material into its existing process, producing the new battery for the Whoop fitness tracker. "We are just upgrading the factories that are being used today," Mr. Berdichevsky said...

Companies like Sila and QuantumScape already have partnerships with carmakers and expect that their batteries will reach automobiles around the middle of the decade. They hope their technologies significantly reduce the cost of electric cars and extend their driving range... They also hope their batteries lead to new devices and vehicles. Smaller, more efficient batteries could spur the development of "smart glasses" — eyeglasses embedded with tiny computers — by allowing designers to pack a more nimble set of technologies into smaller and lighter frames. The same battery technology could invigorate so-called flying cars, a new type of electric aircraft that could ease commutes across major cities later in the decade.
The Times also notes companies like Enovix and Solid Power have been developing improved batteries "for more than a decade, and some hope to move into mass production around 2025."

And as the batteries progress, the Times got an interesting prediction from Venkat Viswanathan, an associate professor of mechanical engineering and materials science at Carnegie Mellon University who specializes in battery technologies. "All aspects of life will become more electrified."

Facebook announced their long-awaited foray into the smart glasses space Thursday morning, launching the Ray-Ban Stories smart glasses in partnership with eyewear giant EssilorLuxottica. From a report: The svelte frames are some of the most low-profile yet available to consumers and will allow users to snap photos and videos with the two onboard 5 MP cameras, listen to music with in-frame speakers and take phone calls. The glasses need to be connected to an iOS or Android device for full functionality, though users can take and store hundreds of photos or dozens of videos on the glasses before transferring media to their phones via Facebook's new View app. The twin cameras will allow users to add 3D effects to their photos and videos once they upload them to the app.

The lightweight glasses weigh less than 50 grams and come with a leather hardshell charging case. The battery lift is advertised as "all-day" which TechCrunch found to be accurate during our review of the frames. Users will be able to control the glasses with a couple physical buttons including a "capture" button to record media and an on-off switch. A touch pad on the right arm of the glasses will allow users to perform functions like swiping to adjust the volume or answering a phone call. An onboard white LED will glow to indicate to the people around the wearer that a video is being recorded. The glasses will start at $299, with polarized and transition lens options coming in at a higher price point.
