Qualcomm has acquired RISC-V startup Ventana to strengthen its CPU ambitions beyond mobile, "reinforcing its commitment and leadership in the development of the RISC-V standard and ecosystem," the company said in a press release. CRN Magazine reports: The San Diego-based company said Ventana's expertise in RISC-V, a free and open alternative to the Arm and x86 instruction set architectures, will enhance its CPU engineering capabilities and complement "existing efforts to develop custom Oryon CPU technology." Financial terms of the deal were not disclosed.

Qualcomm, which has already been using RISC-V for some products outside the PC and server markets, said Ventana's contributions will boost its "technology leadership in the AI era across all businesses," indicating the broad impact expected by this acquisition. "We believe the RISC-V instruction set architecture has the potential to advance the frontier on CPU technology, enabling innovation across products," Durga Malladi, executive vice president and general manager of technology planning, edge solutions and data center for Qualcomm, said in a statement. "The acquisition of Ventana Micro Systems marks a pivotal step in our journey to deliver industry-leading RISC-V-based CPU technology across products."

alternative_right quotes a report from Phys.org: To teach robots how to become tomato pickers, Osaka Metropolitan University Assistant Professor Takuya Fujinaga, Graduate School of Engineering, programmed them to evaluate the ease of harvesting for each tomato before attempting to pick it. Fujinaga's new model uses image recognition paired with statistical analysis to evaluate the optimal approach direction for each fruit. The system involves image processing/vision of the fruit, its stems, and whether it is concealed behind another part of the plant. These factors inform robot control decisions and help it choose the best approach.

The model represents a shift in focus from the traditional 'detection/recognition' model to what Fujinaga calls a 'harvest-ease estimation.' "This moves beyond simply asking 'can a robot pick a tomato?' to thinking about 'how likely is a successful pick?', which is more meaningful for real-world farming," he explained. When tested, Fujinaga's new model demonstrated an 81% success rate, far above predictions. Notably, about a quarter of the successes were tomatoes that were successfully harvested from the right or left side that had previously failed to be harvested by a front approach. This suggested that the robot changed its approach direction when it initially struggled to pick the fruit. "This is expected to usher in a new form of agriculture where robots and humans collaborate," said Fujinaga. "Robots will automatically harvest tomatoes that are easy to pick, while humans will handle the more challenging fruits."

The findings are published in Smart Agricultural Technology.

The Trump administration will allow Nvidia to resume selling H200 chips to China, but only if the U.S. government takes a 25% cut. Axios reports: Trump said on Truth Social that he'll allow Nvidia to sell H200 chips -- the generation of chips before its current, more-advanced Blackwell lineup -- to China, with the U.S. government pocketing a quarter of the revenue. He said he would apply "the same approach to AMD, Intel, and other GREAT American Companies."

American defense hawks fear that China could use Nvidia chips to advance its military ambitions. Trump said Monday that the sales will be subject to "conditions that allow for continued strong National Security." The blockade remains in place for Nvidia's current generation of Blackwell chips, which will be replaced in the second half of 2026 by even more advanced Rubin chips. Huang said recently he was unsure if China would want the older chips. "We applaud President Trump's decision to allow America's chip industry to compete to support high paying jobs and manufacturing in America," Nvidia said in a statement. "Offering H200 to approved commercial customers, vetted by the Department of Commerce, strikes a thoughtful balance that is great for America."

An anonymous reader quotes a report from the Guardian: A coalition of more than 230 environmental groups has demanded a national moratorium on new datacenters in the U.S., the latest salvo in a growing backlash to a booming artificial intelligence industry that has been blamed for escalating electricity bills and worsening the climate crisis. The green groups, including Greenpeace, Friends of the Earth, Food & Water Watch and dozens of local organizations, have urged members of Congress to halt the proliferation of energy-hungry datacenters, accusing them of causing planet-heating emissions, sucking up vast amounts of water and exacerbating electricity bill increases that have hit Americans this year.

"The rapid, largely unregulated rise of datacenters to fuel the AI and crypto frenzy is disrupting communities across the country and threatening Americans' economic, environmental, climate and water security," the letter states, adding that approval of new data centers should be paused until new regulations are put in place. The push comes amid a growing revolt against moves by companies such as Meta, Google and Open AI to plow hundreds of billions of dollars into new datacenters, primarily to meet the huge computing demands of AI. At least 16 datacenter projects, worth a combined $64 billion, have been blocked or delayed due to local opposition to rising electricity costs. The facilities' need for huge amounts of water to cool down equipment has also proved controversial, particularly in drier areas where supplies are scarce. [...]

At the current rate of growth, datacenters could add up to 44m tons of carbon dioxide to the atmosphere by 2030, equivalent to putting an extra 10m cars on to the road and exacerbating a climate crisis that is already spurring extreme weather disasters and ripping apart the fabric of the American insurance market. But it is the impact upon power bills, rather than the climate crisis, that is causing anguish for most voters, acknowledged Emily Wurth, managing director of organizing at Food & Water Watch, the group behind the letter to lawmakers. "I've been amazed by the groundswell of grassroots, bipartisan opposition to this, in all types of communities across the US," said Wurth. "Everyone is affected by this, the opposition has been across the political spectrum. A lot of people don't see the benefits coming from AI and feel they will be paying for it with their energy bills and water."

"It's an important talking point. We've seen outrageous utility price rises across the country and we are going to lean into this. Prices are going up across the board and this is something Americans really do care about."

America's Energy Department runs a research lab in Idaho — and this week announced successful results from a ground-breaking experiment. "This is the first time in history that chloride-based molten salt fuel has been produced for a fast reactor," says Bill Phillips, the lab's technical lead for salt synthesis. He calls it "a major milestone for American innovation and a clear signal of our national commitment to advanced nuclear energy." Unlike traditional reactors that use solid fuel rods and water as a coolant, most molten salt reactors rely on liquid fuel — a mixture of salts containing fissile material. This design allows for higher operating temperatures, better fuel efficiency, and enhanced safety. It also opens the door to new applications, including compact nuclear systems for ships and remote installations.

"The Molten Chloride Fast Reactor represents a paradigm shift in the nuclear fuel cycle, and the Molten Chloride Reactor Experiment (MCRE) will directly inform the commercialization of that reactor," said Jeff Latkowski, senior vice president of TerraPower and program director for the Molten Chloride Fast Reactor. "Working with world-leading organizations such as INL to successfully synthesize this unique new fuel demonstrates how real progress in Gen IV nuclear is being made together."

"The implications for the maritime industry are significant," said Don Wood, senior technical advisor for MCRE. "Molten salt reactors could provide ships with highly efficient, low-maintenance nuclear power, reducing emissions and enabling long-range, uninterrupted travel. The technology could spark the rise of a new nuclear sector — one that is mobile, scalable and globally transformative.
More details from America's Energy Department: MCRE will require a total of 72 to 75 batches of fuel salt to go critical, making it the largest fuel production effort at INL since the operations of Experimental Breeder Reactor-II more than 30 years ago. The full-scale demonstration of the new fuel salt synthesis line for MCRE was made possible by a breakthrough in 2024. After years of testing, the team found the right recipe to convert 95 percent of uranium metal feedstock into 18 kilograms of uranium chloride fuel salt in only a few hours — a process that previously took more than a week to complete...

After delivering the first batch of fuel salt this fall, the team anticipates delivering four additional batches by March of 2026. MCRE is anticipated to run in 2028 for approximately six months at INL in the Laboratory for Operation and Testing (LOTUS) in the United States test bed.
"With the first batch of fuel salt successfully created at INL, researchers will now conduct testing to better understand the physics of the process, with a goal of moving the process to a commercial scale over the next decade," says Cowboy State Daily.

Nuclear engineer Lonnie Johnson worked on NASA's Galileo mission, has more than 140 patents, and invented the Super Soaker water gun. But now he's working on "a potential key to unlock a huge power source that's rarely utilized today," reports the Atlanta Journal-Constitution. [Alternate URL here.]

Waste heat... The Johnson Thermo-Electrochemical Converter, or JTEC, has few moving parts, no combustion and no exhaust. All the work to generate electricity is done by hydrogen, the most abundant element in the universe. Inside the device, pressurized hydrogen gas is separated by a thin, filmlike membrane, with low pressure gas on one side and high pressure gas on the other. The difference in pressure in this "stack" is what drives the hydrogen to compress and expand, creating electricity as it circulates. And unlike a fuel cell, it does not need to be refueled with more hydrogen. All that's needed to keep the process going and electricity flowing is a heat source.

As it turns out, there are enormous amounts of energy vented or otherwise lost from industrial facilities like power plants, factories, breweries and more. Between 20% and 50% of all energy used for industrial processes is dumped into the atmosphere and lost as waste heat, according to the U.S. Department of Energy. The JTEC works with high temperatures, but the device's ability to generate electricity efficiently from low-grade heat sources is what company executives are most excited about. Inside JTEC's headquarters, engineers show off a demonstration unit that can power lights and a sound system with water that's roughly 200 degrees Fahrenheit — below the boiling point and barely warm enough to brew a cup of tea, said Julian Bell, JTEC's vice president of engineering. Comas Haynes, a research engineer at the Georgia Tech Research Institute specializing in thermal and hydrogen system designs, agrees the company could "hit a sweet spot" if it can capitalize on lower temperature heat...

For Johnson, the potential application he's most excited about lies beneath our feet. Geothermal energy exists naturally in rocks and water beneath the Earth's surface at various depths. Tapping into that resource through abandoned oil and gas wells — a well-known access point for underground heat — offers another opportunity. "You don't need batteries and you can draw power when you need it from just about anywhere," Johnson said. Right now, the company is building its first commercial JTEC unit, which is set to be deployed early next year. Mike McQuary, JTEC's CEO and the former president of the pioneering internet service provider MindSpring, said he couldn't reveal the customer, but said it's a "major Southeast utility company." "Crossing that bridge where you have commercial customers that believe in it and will pay for it is important," McQuary said...

On top of some initial seed money, the company brought in $30 million in a Series A funding in 2022 — money that allowed the company to move to its Lee + White headquarters and hire more than 30 engineers. McQuary said it expects to begin another round of fundraising soon.
"Johnson, meanwhile, hasn't stopped working on new inventions," the article points out. "He continues to refine the design for his solid-state battery..."

UPDATE (12/7): The New York Times clarifies today that the damage at Chernobyl hasn't led to a rise in radiation levels: "If there was to be some event inside the shelter that would release radioactive materials into the space inside the New Safe Confinement, because this facility is no longer sealed to the outside environment, there's the potential for radiation to come out," said Shaun Burnie, a senior nuclear specialist at Greenpeace who has monitored nuclear power plants in Ukraine since 2022 and last visited Chernobyl on October 31. "I have to say I don't think that's a particularly serious issue at the moment, because they're not actively decommissioning the actual sarcophagus."

The I.A.E.A. also said there was no permanent damage to the shield's load-bearing structures or monitoring systems. A spokesman for the agency, Fredrik Dahl, said in a text message on Sunday that radiation levels were similar to what they were before the drone hit.
But "A structure designed to prevent radioactive leakage at the defunct Chernobyl nuclear plant in Ukraine is no longer operational," Politico reported Saturday, "after Russian drones targeted it earlier this year, the U.N.'s nuclear watchdog has found." [T]he large steel structure "lost its primary safety functions, including the confinement capability" when its outer cladding was set ablaze after being struck by Russian drones, according to a new report by the International Atomic Energy Agency. Beyond that, there was "no permanent damage to its load-bearing structures or monitoring systems," it said. "Limited temporary repairs have been carried out on the roof, but timely and comprehensive restoration remains essential to prevent further degradation and ensure long-term nuclear safety," IAEA Director General Rafael Mariano Grossi said in astatement.
The Guardian has pictures of the protective shield — incuding the damage from the drone strike. The shield is the world's largest movable land structure, reports CNN: The IAEA, which has a permanent presence at the site, will "continue to do everything it can to support efforts to fully restore nuclear safety and security," Grossi said.... Built in 2010 and completed in 2019, it was designed to last 100 years and has played a crucial role in securing the site.

The project cost €2.1 billion and was funded by contributions from more than 45 donor countries and organizations through the Chernobyl Shelter Fund, according to the European Bank for Reconstruction and Development, which in 2019 hailed the venture as "the largest international collaboration ever in the field of nuclear safety."

"Researchers engineered a strained germanium layer on silicon that allows charge to move faster than in any silicon-compatible material to date," reports Science Daily. "This record mobility could lead to chips that run cooler, faster, and with dramatically lower energy consumption.

"The discovery also enhances the prospects for silicon-based quantum devices..." Scientists from the University of Warwick and the National Research Council of Canada have reported the highest "hole mobility" ever measured in a material that works within today's silicon-based semiconductor manufacturing.... The researchers created a nanometer-thin germanium epilayer on silicon that is placed under compressive strain. This engineered structure enables electric charge to move faster than in any previously known silicon-compatible material...

The findings establish a promising new route for ultra-fast, low-power semiconductor components. Potential uses include quantum information systems, spin qubits, cryogenic controllers for quantum processors, AI accelerators, and energy-efficient servers designed to reduce cooling demands in data centers. This achievement also represents a significant accomplishment for Warwick's Semiconductors Research Group and highlights the UK's growing influence in advanced semiconductor materials research.

To build three-wheeled, solar electric vehicles, Aptera has now launched its "validation" vehicle assembly line, reports the San Diego Business Journal.

"The validation line will set a technical foundation for the company's eventual low-volume assembly line, ensuring that manufacturing processes are optimized and refined, particularly for the company's composite body structure." To date, Aptera has produced three validation vehicles, two of which are in use driving around the San Diego region, with plans to build another 10 in the coming weeks as progress continues on the validation manufacturing line. "You learn things when you start to put miles on vehicles, putting 10s of thousands of miles on these validation vehicles and learning a lot from the durometer of the suspension, ride quality, spring rates and braking pressure," Aptera co-founder and co-CEO Chris Anthony said. "We've been able to incorporate a lot of the usability stuff back, but also, just as we've gone through the process of building these, a lot of order-of-operation stuff that's educated us on what's going to make for the best initial assembly lines," he added....

Aptera made its public debut on October 16, with the company's executive team participating in the Nasdaq closing bell ceremony that evening. Shares of SEV have hovered between $6.50 and $8.50 for much of the company's first month on the exchange. The company's equity line of credit also took effect in mid-November... expected to aid in Aptera generating at least a portion of the $65 million the company has said it will need to complete validation manufacturing and begin low-volume production for customers. Aptera previously raised some $135 million from more than 17,000 investors in what the company touts as the most successful crowdfunding effort of all time, but Anthony argued Aptera will soon need to invest larger sums of capital to scale its production needs.

"Publicly listing the company gives us a lot more funding mechanisms to get into production," he said. "So just having access to the public markets, public liquidity and the kind of instruments and tools that banks offer to public companies, it just seemed like now is the right time." Alongside the IPO, Aptera made its formal transition to a Public Benefit Corporation, giving the company a legal obligation to consider its effect on employees, communities and customers in addition to the profit motives of its shareholders.
California's state government also awarded Aptera $21 million "to support its push toward scaled manufacturing," the article points out.

It also notes that Aptera's vehicles "are technically classified as motorcycles rather than standard passenger cars, presenting a potentially cheaper alternative for consumers on the hunt for an electric vehicle."

CNN's prediction for 2026? "Any device that uses memory, from phones to tablets and smartwatches, could get pricier." But will it be a little or a lot?

The article cites an analysis from multinational strategy/management consulting firm McKinsey & Company which found America's data center demand could continue growing by 20 to 25 percent per year" through 2030. "That's prompted memory manufacturers like Micron and Samsung to shift their focus to data centers, which use a different type of memory, meaning fewer resources for consumer products. (Jaejune Kim, executive VP for memory at Samsung, said in October that their third quarter saw strong demand for memory for AI and data centers, and that they expected the supply shortage for mobile and PC memory to "intensify further.") Memory prices are rising for consumer products because major manufacturers are instead ramping up production for AI data centers as artificial intelligence companies boom. "It's pretty much brutal and crunched across the board," said Yang Wang, a senior analyst at Counterpoint Research.

The International Data Corporation, a global market research firm, reported earlier this week that the smartphone market is expected to decline by 0.9% in 2026 in part because of memory shortages. Memory prices are expected to surge by 30% in the fourth quarter of 2025 and may climb an additional 20% early next year, Counterpoint Research said last month... TrendForce, a research firm that follows the semiconductor industry, estimates memory price hikes have made smartphones 8% to 10% more expensive to produce in 2025 (higher production costs don't always translate into higher consumer prices for a variety of reasons).

Some smartphones could cost more as soon as early next year, said Nabila Popal, a senior research director for the International Data Corporation. Cheap Android phones may see the biggest impact, since less expensive products usually have thinner margins. "It's going to be almost impossible for them to not raise prices" of cheaper Android phones, said Popal. Companies may also postpone phone launches to focus on expensive models that may be more profitable. The average selling price for smartphones is expected to climb to $465 in 2026, compared to $457 in 2025, according to Popal, putting the smartphone market at a record high value of $578.9 billion.

But the pendulum is expected to swing back in the other direction late next year as the supply chain adjusts, according to Popal and Wang, potentially bringing prices back down or at least capping increases.

Meta is acquiring AI wearable startup Limitless, maker of a pendant that records conversations and generates summaries. "We're excited that Limitless will be joining Meta to help accelerate our work to build AI-enabled wearables," a Meta spokesperson said in a statement. CNBC reports: Limitless CEO Dan Siroker revealed the deal on Friday via a corporate blog post but did not disclose the financial terms. "Meta recently announced a new vision to bring personal superintelligence to everyone and a key part of that vision is building incredible AI-enabled wearables," Siroker said in the post and an accompanying video. "We share this vision and we'll be joining Meta to help bring our shared vision to life."

An anonymous reader quotes a report from the New York Times: A few years ago, Paul Wieland, a 44-year-old information technology professional living in New York's Adirondack Mountains, was wrapping up a home renovation when he ran into a hiccup. He wanted to be able to control his new garage door with his smartphone. But the options available, including a product called MyQ, required connecting to a company's internet servers. He believed a "smart" garage door should operate only over a local Wi-Fi network to protect a home's privacy, so he started building his own system to plug into his garage door. By 2022, he had developed a prototype, which he named RATGDO, for Rage Against the Garage Door Opener. He had hoped to sell 100 of his new gadgets just to recoup expenses, but he ended up selling tens of thousands. That's because MyQ's maker did what a number of other consumer device manufacturers have done over the last few years, much to the frustration of their customers: It changed the device, making it both less useful and more expensive to operate.

Chamberlain Group, a company that makes garage door openers, had created the MyQ hubs so that virtually any garage door opener could be controlled with home automation software from Apple, Google, Nest and others. Chamberlain also offered a free MyQ smartphone app. Two years ago, Chamberlain started shutting down support for most third-party access to its MyQ servers. The company said it was trying to improve the reliability of its products. But this effectively broke connections that people had set up to work with Apple's Home app or Google's Home app, among others. Chamberlain also started working with partners that charge subscriptions for their services, though a basic app to control garage doors was still free.

While Mr. Wieland said RATGDO sales spiked after Chamberlain made those changes, he believes the popularity of his device is about more than just opening and closing a garage. It stems from widespread frustration with companies that sell internet-connected hardware that they eventually change or use to nickel-and-dime customers with subscription fees. "You should own the hardware, and there is a line there that a lot of companies are experimenting with," Mr. Wieland said in a recent interview. "I'm really afraid for the future that consumers are going to swallow this and that's going to become the norm." [...] For Mr. Wieland, the fight isn't over. He started a company named RATCLOUD, for Rage Against the Cloud. He said he was developing similar products that were not yet for sale.

A light aircraft crashed in Gloucestershire after a 3D-printed plastic air-induction elbow softened from engine heat and collapsed, cutting power during final approach and causing the plane to undershoot the runway. Investigators say the part was made from "inappropriate material" and safety actions will be taken in the future regarding 3D printed parts. The BBC reports: Following an "uneventful local flight", the AAIB report said the pilot advanced the throttle on the final approach to the runway, and realized the engine had suffered a complete loss of power. "He managed to fly over a road and a line of bushes on the airfield boundary, but landed short and struck the instrument landing system before coming to rest at the side of the structure," the report read.

It was revealed the part had been installed during a modification to the fuel system and collapsed due to its 3D-printed plastic material softening when exposed to heat from the engine. The Light Aircraft Association (LAA) said it now intends to take safety actions in response to the accident, including a "LAA Alert" regarding the use of 3D-printed parts that will be sent to inspectors.

A severe spike in global DRAM prices has pushed Samsung Semiconductor to refuse a long-term RAM order from its own sibling, Samsung Electronics. The move is forcing the smartphone division into short, expensive renegotiations, which will likely mean higher costs for consumer devices. PCWorld reports: Samsung subsidiaries are, naturally, going to look to Samsung Semiconductor first when they need parts. Such was reportedly the case for Samsung Electronics, in search of memory supplies for its newest smartphones as the company ramps up production for 2026 flagship designs. But with so much RAM hardware going into new "AI" data centers -- and those companies willing to pay top dollar for their hardware -- memory manufacturers like Samsung, SK Hynix, and Micron are prioritizing data center suppliers to maximize profits.

The end result, according to a report from SE Daily spotted by SamMobile, is that Samsung Semiconductor rejected the original order for smartphone DRAM chips from Samsung Electronics' Mobile Experience division. The smartphone manufacturing arm of the company had hoped to nail down pricing and supply for another year. But reports say that due to "chipflation," the phone-making division must renegotiate quarterly, with a long-term supply deal rejected by its corporate sibling. A short-term deal, with higher prices, was reportedly hammered out.

A London Assembly report warns that surging demand from "energy-hungry" data centers is straining the electricity grid and delaying new housing developments. With data-center electricity use expected to rise up to 600% by 2050, officials fear London's housing crisis could worsen without coordinated action. The BBC reports: According to the report (PDF) from the London Assembly Planning and Regeneration Committee, some new housing developments in west London were temporarily delayed after the electricity grid reached full capacity. The committee's chair James Small-Edwards said energy capacity had become a "real constraint" on housing and economic growth in the city.

In 2022, the General London Assembly (GLA) began to investigate delays to housing developments in the boroughs of Ealing, Hillingdon and Hounslow - after it received reports that completed projects were being told they would have to "wait until 2037" to get a connection to the electricity grid. There were fears the boroughs may have to "pause new housing altogether" until the issue was resolved. But the GLA found short-term fixes with the National Grid and energy regulator Ofgem to ensure the "worst-case scenario" did not happen -- though several projects were still set back. The strains on parts of London's housing highlighted the need for "longer term planning" around grid capacity in the future, said the report.
