At Tesla's Battery Day Event today, the company unveiled plans to develop a "tabless" battery cell that will make their EV batteries five times more energy dense, six times more powerful, and enable a 16 percent range increase for the company's vehicles. These new "tabless" cells, which Tesla is calling 4860 cells, are "close to working" at the pilot plant level, Musk said. The Verge reports: The company will produce its new batteries in-house, which Tesla CEO Elon Musk predicts will help dramatically reduce costs and allow the company to sell electric vehicles for the same price as gasoline-powered ones. The battery is expected to lower Tesla's cost per kilowatt-hour, the unit of energy most commonly used to measure the capacity of the battery packs in modern electric vehicles. Many experts believe that lowering these costs would allow Tesla to dramatically lower the price of its cars, thereby making them far more accessible. Musk's announcement that Tesla will begin manufacturing its own batteries should help with the shortages the company has experienced in the past with Panasonic and its other suppliers.

With that said, Tesla won't stop purchasing those batteries anytime soon. "In the run-up to Battery Day, Musk tweeted that the company would continue to use batteries supplied by Panasonic, China's CATL, LG Chem, and others," notes The Verge. "Not only that, but Tesla would buy more batteries from its suppliers than normal."

An anonymous reader quotes a report from CBC.ca: Royal Dutch Shell is looking to slash up to 40 percent off the cost of producing oil and gas in a major drive to save cash so it can overhaul its business and focus more on renewable energy and power markets, sources told Reuters. Shell's new cost-cutting review, known internally as Project Reshape and expected to be completed this year, will affect its three main divisions and any savings will come on top of a $4 billion US target set in the wake of the COVID-19 crisis. Shell now wants to focus its oil and gas production on a few key hubs, including the Gulf of Mexico, Nigeria and the North Sea, the sources said. The company's integrated gas division, which runs Shell's liquefied natural gas (LNG) operations as well as some gas production, is also looking at deep cuts, the sources said. For downstream, the review is focusing on cutting costs from Shell's network of 45,000 service stations -- the world's biggest which is seen as one its "most high-value activities" and is expected to play a pivotal role in the transition, two more sources involved with the review told Reuters.

The review, which company sources say is the largest in Shell's modern history, is expected to be completed by the end of 2020 when Shell wants to announce a major restructuring. It will hold an investor day in February 2021. Teams in Shell's three main divisions are also studying how to reshape the business by cutting thousands of jobs and removing management layers both to save money and create a nimbler company as it prepares to restructure, the sources said. Besides cutting costs at its downstream retail business, Shell is pressing ahead with plans to reduce the number of its oil refineries to 10 from 17 last year. It has already agreed to sell three. The review of refining operations also includes finding ways to sharply increase the production of low-carbon fuels such as biofuels, chemicals and lubricants. That could be done by using low-carbon raw materials such as cooking oil, one source said. "We had a great model but is it right for the future? There will be differences, this is not just about structure but culture and about the type of company we want to be," said a senior Shell source, who declined to be named.

Samsung has unveiled its next high-performance NVMe 2280-sized M.2 drive, the 980 Pro. So far, it comes in three capacities shipping this month: 250GB for $89.99, 500GB for $149.99, and 1TB for $229.99. A 2TB model will arrive later this year, but Samsung didn't share a price. From a report: The standout feature of this drive is its compatibility with M.2 slots over the PCIe 4.0 interface. If you have a compatible motherboard, Samsung says the 980 Pro can go on a tear with sequential read / write speeds of up to 7,000MB/s and 5,000MB/s, respectively. It claims that this is two times faster performance than PCIe 3.0 SSDs and nearly 13 times faster than the more affordable but slower SATA SSDs. Of course, to get the best speeds out of this Samsung M.2 drive, you'll need a compatible motherboard with a PCIe 4.0 M.2 slot. Adoption of the tech is starting to ramp up, including mainstream computing products like AMD's third-generation Ryzen CPUs, its Radeon RX 5700 and 5700XT GPUs, and more recently, Nvidia's RTX 3080 graphics card. Sony and Microsoft are also using the technology for their custom SSD technologies in the PS5 and Xbox Series S / X consoles.

Airbus has announced plans for the world's first zero-emission commercial aircraft models that run on hydrogen and could take to the skies by 2035. The Guardian reports: The European aersospace company revealed three different aircraft concepts that would be put through their paces to find the most efficient way to travel long distances by plane without producing the greenhouse gas emissions responsible for global heating. UK holidaymakers and business travellers could fly from London to the Canary Islands, Athens or eastern Europe without producing carbon emissions, should the plans become a commercial reality.

All three of the aircraft concepts rely on hydrogen as a fuel because the only emissions produced when it is burned is water vapor, making it a clean fuel option for heavy vehicles such as planes, trains and trucks. The first of the Airbus concepts could carry between 120 and 200 passengers more than 2,000 nautical miles by using a turbofan design that includes a modified gas-turbine engine running on hydrogen, rather than jet fuel, which could be stored in tanks located behind the plane's rear pressure bulkhead. The second concept, a turboprop design, would also use a modified gas engine but could carry up to 100 passengers for 1,000 nautical miles on short-haul trips.

The aviation giant's plans also include a plane with an "exceptionally wide" body that blends into the plane's wings to open up multiple options for hydrogen storage and the cabin layout. This plane could carry as many passengers as the turbofan design and travel as far too. [...] Airbus said hydrogen planes would also require airports to install hydrogen transport and refueling infrastructure, and government support to upgrade aircraft fleets to allow airlines to retire their older, less environmentally friendly aircraft sooner than planned.

As chip makers have reached the limits of atomic-scale circuitry and the physics of electrons, Moore's law has slowed, and some say it's over. But a different law, potentially no less consequential for computing's next half century, has arisen. WSJ: I call it Huang's Law, after Nvidia chief executive and co-founder Jensen Huang. It describes how the silicon chips that power artificial intelligence more than double in performance every two years. While the increase can be attributed to both hardware and software, its steady progress makes it a unique enabler of everything from autonomous cars, trucks and ships to the face, voice and object recognition in our personal gadgets. Between November 2012 and this May, performance of Nvidia's chips increased 317 times for an important class of AI calculations, says Bill Dally, chief scientist and senior vice president of research at Nvidia. On average, in other words, the performance of these chips more than doubled every year, a rate of progress that makes Moore's Law pale in comparison.

Nvidia's specialty has long been graphics processing units, or GPUs, which operate efficiently when there are many independent tasks to be done simultaneously. Central processing units, or CPUs, like the kind that Intel specializes in, are on the other hand much less efficient but better at executing a single, serial task very quickly. You can't chop up every computing process so that it can be efficiently handled by a GPU, but for the ones you can -- including many AI applications -- you can perform it many times as fast while expending the same power. Intel was a primary driver of Moore's Law, but it was hardly the only one. Perpetuating it required tens of thousands of engineers and billions of dollars in investment across hundreds of companies around the globe. Similarly, Nvidia isn't alone in driving Huang's Law -- and in fact its own type of AI processing might, in some applications, be losing its appeal. That's probably a major reason it has moved to acquire chip architect Arm Holdings this month, another company key to ongoing improvement in the speed of AI, for $40 billion.

Daimler, which has worked on hydrogen technology for decades, is developing a fuel-cell semi with range of up to 600 miles per fueling and next-generation battery trucks amid intensifying competition to curb diesel and carbon exhaust from heavy-duty vehicles. Forbes reports: The German auto giant's truck unit showed off the Mercedes-Benz GenH2, a concept truck designed for long haul runs that will be tested by customers in 2023, at an event in Berlin Tuesday outlining steps it's taking to meet the goals of the Paris Climate Agreement. Volume production of GenH2s starts in the second half of the 2020s. The company also debuted its Mercedes-Benz eActros LongHaul, a battery-powered truck for short- and medium-range routes goes about 300 miles (500 kilometers) between charges. eActros production starts in 2024.

Both trucks share Daimler's new ePowetrain modular platform to help hold costs down. They'll be available initially in Europe, though versions for North America and Japan will arrive around the same time, the company said. [...] A unique twist with Daimler's GenH2 truck is that the system relies on liquid hydrogen, rather than highly compressed hydrogen gas, the current standard. The benefit is that liquid hydrogen is more energy dense and uses tanks that are much lighter than those required for gaseous fuel, Daimler said. "This gives the trucks a larger cargo space and higher payload weight," while also improving range, it said. The combination of hydrogen and battery vehicles "enables us to offer our customers the best vehicle options, depending on the application," Daimler Chairman Martin Daum said at the event. "Battery power will be rather used for lower cargo weights and for shorter distances. Fuel-cell power will tend to be the preferred option for heavier loads and longer distances."

MojoKid writes: NVIDIA CEO Jensen Huang officially unveiled the GeForce RTX 30 series based on the company's new Ampere architecture a couple of weeks back. According to Huang, the GeForce RTX 30 series represents the greatest generational leap in the company's history and he claimed the GeForce RTX 3080 would offer double the performance of its predecessor. The embargo for GeForce RTX 3080 reviews just lifted and it seems NVIDIA was intent on making good on its claims. The GeForce RTX 3080 is the fastest GPU released to date, across the board, regardless of the game, application, or benchmarks used. Throughout testing, the GeForce RTX 3080 often put up scores more than doubling the performance of AMD's current flagship Radeon RX 5700 XT. The RTX 3080 even skunked the NVIDIA Titan RTX and GeForce RTX 2080 Ti by relatively large margins, even though it will retail for almost half the price of a 2080 Ti (at least currently). The bottom line is, NVIDIA's got an absolutely stellar-performing GPU on its hands, and the GeForce RTX 3080 isn't even the best Ampere has to offer, with the RTX 3090 waiting in the wings. GeForce RTX 3080 cards will be available from NVIDIA and third-party board partners on 9/17 for an entry-level MSRP of $699.

According to Apple Insider, Apple is researching an Apple Watch band that could contain controllable protrusions to present tactile information on the surface. From the report: Apple has famously always researched providing accessibility features in its devices, whether or not it's profitable. However, so far there has been a limit to what the Apple Watch can do -- and its bands could have no accessibility features at all. "Tactile output for wearable device," is a newly granted US patent which aims to change that. Alongside the various things Siri can say aloud since the Apple Watch Series 3, there could now be Apple-designed bands that display Braille information.

While Apple wants its patent to cover any kind of electronic device possible, most of its descriptions and all of its drawings refer to the Apple Watch and to what Apple refers to as actuators. These are components that respond to a processor and cause other elements to move or rearrange. "[For example, a] wearable item comprises a flexible strap and actuators within the flexible strap," says the patent. "The actuators are configured to dynamically form protrusions along the flexible strap. The protrusions present tactilely-perceptible information." These protrusions are similar to the raised dots in Braille, but Apple says they needn't be confined to that one system. Rather than following the established patterns of whole words in Braille, the same protrusions could be configured to "also or instead be dynamically and/or selectively actuated to form [the] shapes of alphanumeric characters."

Apple today introduced a redesigned iPad Air that looks more like an iPad Pro, as well as an updated 8th-generation, entry-level iPad. MacRumors reports on the new iPad Air: Apple today introduced a redesigned iPad Air with slimmer bezels, paving the way for an all-screen design similar to recent iPad Pro models. In addition, the new iPad Air is the first Apple device with Touch ID built into the power button. The new iPad Air is powered by the new 5nm-based, six-core A14 Bionic chip for up to 40 percent faster performance and up to 30 percent faster graphics than the previous-generation iPad Air.

The device features a fully laminated 10.9-inch Liquid Retina display with True Tone, P3 wide color support, and an anti-reflective coating. Following in the footsteps of the iPad Pro, the new iPad Air features a USB-C port instead of a Lightning connector. The device also features the same 12-megapixel rear camera used in the iPad Pro for higher-resolution photos and 4K video recording. The new iPad Air will be available starting in October on Apple.com and the Apple Store app in 30 countries and regions. Wi-Fi models will start at $599, while cellular models will start at $729, with 64GB and 256GB storage capacities available. There will be five colors to choose from, including silver, space gray, rose gold, green, and sky blue. 9to5Mac reports on the 8th-generation iPad: Apple today announced the 8th-generation iPad, featuring an A12 chip compared to the previous-generation's A10 processor. The design of the new entry-level iPad is largely the same as its predecessor. The jump from A10 to A12 means Apple's cheapest iPad will feature the Neural Engine for the first time. Apple says the A12 chip offers more than twice the performance of the top selling Windows laptop, 6x faster than the top-selling Android tablet and 6x faster than the best-selling Chromebook. The 8th-generation iPad keeps the same price as the 7th-gen: that's $329 for general sale and $299 for education.

Apple on Tuesday announced it would no longer be including USB power adapters with Apple Watch devices as part of an effort to reduce its environmental impact. From a report: Removing the power adapter means new Apple Watch customers won't have access to the device that plugs into the wall, but they should still receive Apple's custom Apple Watch cable that recharges the device wirelessly. According to Bloomberg's Mark Gurman, this move won't be restricted to Apple Watch devices; it will also include upcoming iPhones.

An anonymous reader shares a report: Seems everything charges a monthly fee, these days. It also seems that every Apple event brings another way to fork over $10 a month to the company. This time out, it was the addition of Fitness+, which brings metric-focused video workouts to an Apple TV near you. To keep things simple (and to keep you subscribing), the company is offering up a trio of new Apple One bundles. It's not quite mix and match yet, but there are three pricing tiers. Individual offers Apple Music, TV+, Arcade and iCloud for $15 a month. The Family version will get you those four services for $20 a month. For the hardcore, there's the $30 a month Premier tier, which bundles iCloud, Music, TV+, Arcade, News+ and Fitness+.

On Tuesday, Apple will hold its annual September event called "Time Flies." Unlike in previous years, the company is not expected to announce new iPhones as they have reportedly been delayed "a few weeks" due to the pandemic. Macworld reports on what we can expect to see announced instead: Apple's invitation was light on details, as always, but it's hard to look at its "Time Flies" tagline and think that this won't mean showing off new models of the Apple Watch. Presumably that means a Series 6, but rumors have also circulated around an additional lower cost model to replace the aging Series 3. [...] While the iPad Pro received a minor update this past spring, the midrange iPad Air has remained unchanged since March 2019. Eighteen months is about the refresh cycle for iPads these days, so a revamped Air seems like a pretty good bet for this week's event. [...] There also remains the question of the iPad mini, last updated at the same time as the Air. It could very well see a similar update to stay in step with the Air, but given that Apple has often let the smaller tablet lie unchanged for years at a time -- which it seems to do with many products with the "mini" moniker -- it's hardly a sure thing.

With new hardware naturally comes new software. The release of a new Apple Watch will certainly require watchOS 7, which in turn will need iOS 14. Likewise, new iPads are unlikely to ship without iPadOS 14. That gibes with a recent Bloomberg report that iOS 14 would be released in mid-September, following the usual schedule for Apple's mobile operating system updates. And given our brave new world where Apple events are not subject to the typical restrictions of time and scheduling, that might be all we have to look forward to this time around. That said, there are plenty of other things that Apple could talk about at this event, assuming they're ready to go -- everything from over-the-head AirPods to Apple silicon-powered Macs.

An anonymous reader quotes a report from VentureBeat, written by Emil Protalinski: Founded in 1992, Boston Dynamics is arguably the best-known robot company around, in part because its demonstration videos tend to go viral. Now it is attempting to transform from an R&D company to a robotics business, with an eye on profitability for the first time. When we interviewed Boston Dynamics founder and former CEO Marc Raibert in November 2019, we discussed the company's customers, potential applications, AI, simulation, and those viral videos. But it turns out Raibert was transitioning out of the CEO role at the time -- current CEO Robert Playter told us in an interview this month that he took the helm in November. We sat down to discuss Playter's first year as CEO; profitability; Spot, Pick, Handle, and Atlas; and the company's broader roadmap, including which robots are next.
[...]
In June, Boston Dynamics started selling its quadruped robot Spot in the U.S. for $74,500. Last week, the company expanded Spot sales to Canada, the EU, and the U.K. at the same price point. Playter says Boston Dynamics has sold or leased about 250 robots to date and business is accelerating. [...] Compared to big manufacturing robotic companies, 250 robots is not a lot. But Playter points out it's a big achievement "for a novel robot like Spot." Other robotic startups would love to get that sort of market validation. "We're penetrating, we're establishing a market, and people are starting to see value. We're adapting Spot to be a solution for some of the industries we're targeting," Playter said.

Spot's success means the company is beating its own internal targets. "We are meeting -- actually exceeding -- some of our sales goals for Spot," Playter said. "We had ambitious goals this year, but we met our Q1 goal. We're meeting our Q2 goal. We have ambitious Q3 and Q4 goals. I think we're probably going to meet or exceed them this year. To become profitable, these products do have to become successful. They have to scale. But right now, I think we're beating plan." The company now has a roadmap to profitability. "I think we'll be profitable in about two and a half years," Playter said. "2023-2024 is when I'm projecting that we are cash positive." To hit that milestone, Boston Dynamics is simultaneously developing robots for logistics (think production, packaging, inventory, transportation, and warehousing)...

In late 2016, Nikola Motor Company founder Trevor Milton unveiled a prototype of the Nikola One truck, claiming it "fully functions and works, which is really incredible." A couple years later, in January 2018, the company showed the Nikola One truck moving rapidly along a two-lane desert highway. But last week, the short-selling investment firm Hindenburg Research published a bombshell report, accusing Nikola Motors of massive fraud, having no proprietary technology and vastly overstating the capabilities of their prototypes to investors.

Incredibly, "Hindenburg reported that the truck in the 'Nikola One in motion' video wasn't moving under its own power," reports Ars Technica. "Rather, Nikola had towed the truck to the top of a shallow hill and let it roll down. The company allegedly tilted the camera to make it look like the truck was traveling under its own power on a level roadway." From the report: On Monday morning, Nikola sent out a lengthy press release titled "Nikola Sets the Record Straight on False and Misleading Short Seller Report." While the statement nitpicks a number of claims in the Hindenburg report, it tacitly concedes Hindenburg's main claim about the Nikola One. Nikola now admits that the Nikola One prototype wasn't functional in December 2016 and still wasn't functional when the company released the "in motion" video 13 months later. Nikola claims that the gearbox, batteries, inverters, power steering, and some other components of the truck were functional at the time of the December 2016 show. But Nikola doesn't claim that the truck had a working hydrogen fuel cell or motors to drive the wheels -- the two key components Hindenburg stated were missing from the truck in December 2016.

And Nikola now admits that it never got the truck to fully function. "As Nikola pivoted to the next generation of trucks, it ultimately decided not to invest additional resources into completing the process to make the Nikola One drive on its own propulsion," Nikola wrote in its Monday statement. Instead, Nikola pivoted to working on its next vehicle, the Nikola Two. So what about that video of the Nikola One driving across the desert? "Nikola never stated its truck was driving under its own propulsion in the video," Nikola wrote. "Nikola described this third-party video on the Company's social media as 'In Motion.' It was never described as 'under its own propulsion' or 'powertrain driven.' Nikola investors who invested during this period, in which the Company was privately held, knew the technical capability of the Nikola One at the time of their investment."

An anonymous reader quotes a report from TechCrunch: Arm Holdings, the U.K. semiconductor company, made history for the second time today, becoming the country's biggest tech exit when Nvidia announced over the weekend that it would buy it from SoftBank for $40 billion in an all-stock deal. (Arm's first appearance in the record books? When SoftBank announced in 2016 that it would acquire the company for $32 billion.) But before you can say advanced reduced instruction set computing machine, the deal has hit a minor hitch. One of Arm's co-founders has started a campaign to get the U.K. to interfere in the deal, or else call it off and opt for a public listing backed by the government.

Hermann Hauser, who started the company in 1990 along with a host of others as a spin-out of Acorn Computers, has penned an open letter to the U.K.'s Prime Minister Boris Johnson in which he says that he is "extremely concerned" about the deal and how it will impact jobs in the country, Arm's business model and the future of the country's economic sovereignty independent of the U.S. and U.S. interests. Hauser has also created a site to gather public support -- savearm.co.uk -- and to that end has also started to collect signatures from business figures and others. He's calling on the government to intervene, or to at least create legally binding provisions, tied to passing the deal to guarantee jobs, create a way to enforce Nvidia not getting preferential treatment over other licensees and secure an exemption from CFIUS regulation "so that U.K. companies are guaranteed unfettered access to our own microprocessor technology." "This puts Britain in the invidious position that the decision about who ARM is allowed to sell to will be made in the White House and not in Downing Street," he writes. "Sovereignty used to be mainly a geographic issue, but now economic sovereignty is equally important. Surrendering UK's most powerful trade weapon to the US is making Britain a US vassal state."

Meanwhile, Nvidia CEO and co-founder Jensen Huang said: "This will drive innovation for customers of both companies," adding that Nvidia "will maintain Arm's open licensing model and customer neutrality... We love Arm's business model. In fact, we intend to expand Arm's licensing portfolio with access to Nvidia's technology. Both our ecosystems will be enriched by this combination." Hauser responded by saying: "Do not believe any statements which are not legally binding."

The coronavirus pandemic has the potential to permanently replace some humans with machines, according to a new study on Monday from the Federal Reserve Bank of Philadelphia. From a report: Layoffs have been higher among workers in industries that can be automated, which increases the risk those jobs will become permanently obsolete, according to the study by economists Lei Ding and Julieth Saenz Molina. At the same time, the spread of Covid-19 has accelerated automation in industries that have been hit hard by the virus or that don't permit remote work. The longer the recession lasts, the deeper the impact of automation will be. "In case the COVID-19 crisis evolves into a prolonged economic crisis, many job losses in automatable occupations could become permanent in the post-pandemic economy, similar to what happened during the recovery from the Great Recession," Ding and Saenz Molina wrote. Industries that were already facing a high risk of automation lost 4.2 more jobs per 100 than jobs in sector facing fewer threats by technology, the study shows, which analyzes data through August.

Two years ago, Microsoft sank a data centre off the coast of Orkney in a wild experiment. That data centre has now been retrieved from the ocean floor, and Microsoft researchers are assessing how it has performed, and what they can learn from it about energy efficiency. From a report: Their first conclusion is that the cylinder packed with servers had a lower failure rate than a conventional data centre. When the container was hauled off the seabed around half a mile offshore after being placed there in May 2018, just eight out of the 855 servers on board had failed. That compares very well with a conventional data centre. "Our failure rate in the water is one-eighth of what we see on land," says Ben Cutler, who has led what Microsoft calls Project Natick. The team is speculating that the greater reliability may be connected to the fact that there were no humans on board, and that nitrogen rather than oxygen was pumped into the capsule.

The Sacramento Bee published a video showing dozens of oil tankers anchored off California's coast as the current demand for oil plummets. But looking toward the future, they've also published along with it a special warning from the director of the nonprofit Center for Biological Diversity's Climate Law Institute: California Resources Corporation, the state's largest oil and gas producer, is the latest oil producer to seek bankruptcy, aiming to wipe out more than $5 billion in debt and equity interests... This bankrupt company also faces more than $1 billion in costs to properly plug and abandon its 18,700 wells in the state. That problem goes far beyond CRC. A state-commissioned report found that cleaning up California's 107,000 oil and gas wells could cost a staggering $9.2 billion.

Saddling taxpayers with cleanup costs after pocketing the profits would be outrageous, yet many oil producers have done just that, walking away from millions of wells across the U.S. With more bankruptcies coming, the risk that oil companies weasel out of well cleanup keeps increasing... The risks aren't just financial. When wells sit idle, they corrode and leak. Experts point to nearly 75,000 wells in California that are "idle" or near-idle, producing little to no oil, or "orphaned," having no viable or responsible operator... [M]ethane frequently leaked by idle wells is a greenhouse gas that warms the planet 87 times more than the same amount of carbon dioxide over a 20-year period. Potentially tens of thousands of idle wells are leaking methane into the air, worsening climate change and increasing the risk and magnitude of heat waves and fires like those we're suffering now.

Yet Governor Newsom's administration keeps rewarding this polluting industry, including CRC. This year, state oil regulators have issued more than 1,600 permits for new wells. More than 300 went to CRC. This will only increase cleanup costs once wells stop producing or their owners go bust. Even if the state stopped issuing permits today, plugging and cleaning up existing wells at the current snail's pace will take decades. California can't just keep approving drilling, waiting for this tottering industry to collapse. We need a plan for a managed, just transition.

One solution gives Gov. Newsom a chance to tackle multiple problems at once: accelerating well remediation. By using the state's authority to speed well cleanup we can reduce the environmental and fiscal risk from these wells and create good jobs.

"SoftBank is set to sell the U.K.'s Arm Holdings to U.S. chip company Nvidia for more than $40 billion," writes Ars Technica, adding that the deal's imminent announcement was reported earlier by the Wall Street Journal. The move comes just four years after Softbank bought ARM, promising it would become their company's linchpin: Multiple people with direct knowledge of the matter said a cash-and-stock takeover of Arm by Nvidia may be announced as soon as Monday, and that SoftBank will become the largest shareholder in the U.S. chip company.

The announcement of the deal hinged on SoftBank ending a messy dispute between Arm and the head of its China joint venture, Allen Wu, who earlier rebuffed an attempt to remove him and claimed legal control of the unit. Several people close to SoftBank said the matter was now "resolved," though one person close to Mr Wu said he "remains the chairman of Arm China." A spokesperson for Mr Wu declined to comment.

The takeover values Arm above the $32 billion price that SoftBank paid for the business in 2016, a deal that was struck weeks after the U.K. voted to leave the European Union and prompted critics including Arm's founder to accuse the country of selling off the crown jewel of its tech sector. While Nvidia is paying more for the asset than SoftBank did, the price also reflects the scale of Arm's underperformance under the Japanese group's ownership. Nvidia had a market valuation of roughly similar to that of Arm's at the time of the 2016 deal, but now trades with a market value of $300 billion, or roughly 10 times the amount SoftBank paid in cash for Arm. By paying for a large portion of the deals with its own shares, it is also passing part of the risk of the transaction to SoftBank. For Nvidia, which recently overtook Intel to become the world's most valuable chipmaker, the deal will further consolidate the US company's position at the centre of the semiconductor industry...

One person close to the talks said that Nvidia would make commitments to the UK government over Arm's future in Britain, where opposition politicians have recently insisted that any potential deal must safeguard British jobs.

"Scientists have known for nearly 200 years that certain materials can convert heat to electricity..." reports Science, describing research into an intriguing new approach: Refrigerators, boilers, and even lightbulbs continually dump heat into their surroundings. This "waste heat" could — in theory — be turned into electricity, as it is sometimes done with power plants, automobile engines, and other high-heat sources. The problem: These "low-grade" sources give off too little heat for current technology to do the conversion well.

Now, researchers have created a device that uses liquids to efficiently convert low-grade heat to electricity. The advance might one day power energy-scavenging devices that can light up sensors and lights and even charge batteries... Thermocells are good at converting small temperature differences into electricity, but they typically produce only tiny currents... This thermocell generated five times more power for the same electrode area than previous versions, materials physicist Jun Zhou and his colleagues at the Huazhong University of Science and Technology report this week in Science.

It also more than doubled the efficiency needed to make a viable commercial device. A paperback book-size module of 20 thermocells could run LED lights, power a fan, and charge a mobile phone, the team found.
