Tesla has produced the first Semi from its new high-volume production line at Gigafactory Nevada, a milestone for the long-delayed electric Class 8 truck program after years of pilot builds and delays. Electrek reports: The Tesla Semi has had one of the longest gestation periods in Tesla's history. First unveiled in 2017, the truck was originally promised for production in 2019. That target slipped repeatedly -- to 2020, then 2021, then 2022 -- before Tesla finally delivered a handful of units to PepsiCo in late 2022. Those early trucks were essentially hand-built on a pilot line. Tesla spent the next three years refining the design, cutting roughly 1,000 lbs from the truck, and building out a dedicated factory adjacent to Gigafactory Nevada in Sparks. The company revealed the final production specs in February, confirming two trims: a Standard Range with 325 miles at full 82,000-lb gross combination weight, and a Long Range with 500 miles of range.

Tesla is quoting $290,000 for the 500-mile Long Range version and roughly $260,000 for the Standard Range -- making it the lowest-priced Class 8 battery electric tractor on the market. The shift from a pilot line to a high-volume production line is significant. Tesla's Semi factory is designed for an annual capacity of 50,000 trucks, though the company will ramp gradually. Analysts project deliveries between 5,000 and 15,000 units in 2026, but that sounds way too optimistic. [...] Both trims feature an 800-kW tri-motor drivetrain producing 1,072 hp and support 1.2-MW Megacharger speeds, restoring 60% of range in roughly 30 minutes -- conveniently timed around a driver's mandatory rest break. Tesla has opened its first Megacharger station in Ontario, California, and has mapped 66 Megacharger locations across 15 states.

An anonymous reader quotes a report from Ars Technica: Humanoid robots are getting a new gig as baggage handlers and cargo loaders at Tokyo's Haneda Airport -- part of a Japan Airlines experiment to address a human labor shortage as airport visitor numbers have surged in recent years. The demonstration, set to launch in May 2026, could eventually test humanoid robots in a wide range of airport tasks, including cleaning aircraft cabins and possibly handling ground support equipment such as baggage carts, according to a Japan Airlines press release. The trials are scheduled to run until 2028, which suggests that travelers flying into or out of Tokyo may spot some of the robots at work.

[...] Japan Airlines is interested in testing whether humanoid robots powered by some of the latest AI models can adapt more readily to human work environments -- such as airports -- without requiring dedicated work stations or other significant workplace modifications. The airline's subsidiary, JAL Ground Service, has teamed up with GMO AI & Robotics Corporation to oversee the demonstration. The Japanese companies will test the G1 robot and Walker E robot from Chinese companies Unitree Robotics and UBTECH Robotics, according to The Asia Business Daily. Humanoid robots still typically cost tens of thousands of dollars per unit despite Chinese robotics manufacturers scaling up mass production, although the Unitree G1 robot costs as low as $13,500 for the baseline model.

A new video from an apparently staged demonstration in an aircraft hangar shows one of the humanoid robots tottering up to a large, metal cargo container and making a vague pushing gesture. But the cargo container only begins to move once a human worker starts the conveyor belt to move the container toward the aircraft. Presumably, the robots will need to put in much more effective work if they're to prove as productive as human airport workers. Having robots working directly alongside humans will also introduce new safety considerations for airports like Haneda Airport, which is Japan's second-largest airport, with flights arriving approximately every two minutes. The first step in the pilot program will involve identifying which airport areas will be safest for humanoid robots.

fjo3 shares a report from The Times: More than two-thirds of babies under two use screens, a report has found, and some are exposed for up to eight hours a day. Nearly a third of newborns were found to be watching screens for more than three hours a day, while almost 20 percent of infants of four to 11 months used screens for more than an hour a day. The report comes after the government issued guidance that children under two do not use screens at all, apart from communal activities such as video-calling relatives.

In a review of the current research, researchers found evidence linking screen time to poorer outcomes for children, including an increased risk of obesity, short-sightedness, sleep and behavioural difficulties, and later challenges with friendships. [...] The research also revealed why children and parents use screens, with families reporting children doing so for educational purposes, entertainment, play and to communicate and bond with others. Parents, meanwhile, used screens to occupy or distract children, which helped caregivers to complete domestic duties, paid employment and other caring responsibilities. Nearly a quarter of parents -- 23.6 percent -- either had no childcare or were not aware of the government's early years offer.

The Trump administration says it will reimburse energy companies $885 million to cancel two planned offshore wind farms, with the firms in turn agreeing to put money into oil and gas projects instead. "The deals are modeled after a similar agreement last month with the French energy giant TotalEnergies," notes the New York Times. "TotalEnergies forfeited its leases for two wind projects planned off the coasts of New York and North Carolina, while committing to a range of fossil-fuel investments." From the report: [...] The first new agreement affects Bluepoint Wind, a wind farm in the early stages of development off New York and New Jersey. The project was proposed by Global Infrastructure Partners, a part of asset manager BlackRock, and Ocean Winds, which is itself a joint venture between Engie and EDP Renewables, two European clean-energy firms. The second deal would cancel Golden State Wind, another early-stage venture off California's central coast. Golden State Wind is a 50-50 partnership between the developers Ocean Winds and Reventus Power.

Both Bluepoint Wind and Golden State Wind agreed not to pursue any new offshore wind projects in the United States, although that pledge would not necessarily apply to the companies behind the ventures. Ocean Winds has also been developing another giant wind farm known as SouthCoast Wind, off Martha's Vineyard, Mass., that is much further along in the planning and permitting process. That project is not affected by Monday's announcement, although it has essentially been paused since Mr. Trump took office last year. [...] It is also unclear how much the companies will actually invest in new fossil fuel infrastructure. In documents released this month, Interior revealed that it would count investments that TotalEnergies made before the deal toward its pledge, raising questions over whether the company had any obligations to make additional investments.

Framework began shipping its new Laptop 13 Pro this week. And the Ubuntu variant is outselling the Windows variant, reports PC World: [I]t's selling quickly by Framework's internal metrics, with six batches of the Intel version of the laptop already sold out. [A later Framework social media post added "Spoke too soon, we're onto Batch 8."]

"Also nice validation of our approach, the Ubuntu configurations are outselling the Windows ones!"

That's not really surprising, for a few reasons. One, if you're buying a Framework laptop, you have a good reason to order it without an OS, even if you want Windows 11. It's easy to get it free or cheap elsewhere. (Framework says it's not counting the "None (bring your own)" option in these Ubuntu numbers.) Two, there are precious few places to order a new laptop with any kind of Linux pre-loaded — you've got Framework, a few smaller vendors like System76 and Slimbook, and a few models from Dell. Lenovo sold Ubuntu-loaded laptops at one point, but I can't find any on the site right now...

Perhaps it doesn't hurt that Microsoft and Windows are currently on a bit of an apology tour. After a couple of years of pushing hard on "AI" features that no one wants — not even the people who do want "AI" want the Copilot flavor — Microsoft is pulling back its integration into everything and now promising features that Windows has been missing ever since Windows 10.
Framework also reports that:

• More than one third of purchasers say they're replacing a MacBook Pro, "and almost all of them are switching to Linux (based on our optional post-purchase survey)."

• "Also in interesting sales data, the Gray/Black keyboard is vastly outselling the traditional Black one!"

An anonymous reader shared this report from the Associated Press: The 1986 Chernobyl disaster fueled global fears about nuclear power and slowed its development in Europe and elsewhere. Four decades later, however, there's a revival around the world, a trend that has been given a big boost by war in the Middle East. Over 400 nuclear reactors are operational in 31 countries, while about 70 more are under construction. Nuclear power accounts for producing about 10% of the world's electricity, equivalent to about a quarter of all sources of low-carbon power.

Nuclear reactors have seen steady improvements, adding more safety features and making them cheaper to build and operate. While Chernobyl and the 2011 Fukushima nuclear disaster in Japan diminished the appetite for such power sources, it was clear years ago that there probably would be a revival, said Fatih Birol, executive director of the International Energy Agency. With the war in the Middle East, "I am 100% sure nuclear is coming back," he added...

The United States is the world's largest producer of nuclear power, with 94 operational reactors accounting for about 30% of global generation of nuclear electricity. And it is increasing efforts to develop nuclear energy capacity with a goal to quadruple it by 2050... China operates 61 nuclear reactors and is leading the world in building new units, with nearly 40 under construction with a goal to surpass the U.S. and become the global leader in nuclear capacity. European Commission chief Ursula von der Leyen has acknowledged that it was Europe's "strategic mistake" to cut nuclear energy and outlined new initiatives to encourage building power plants. [In 1990, nuclear energy accounted for roughly a third of Europe's electricity, the article points out, but it's now only about 15%.] Russia, meanwhile, has taken a strong lead in exporting its nuclear know-how, building 20 reactors worldwide...

Japan has restarted 15 reactors after reviewing the lessons of the earthquake and tsunami that damaged the Fukushima plant, and 10 more are in the process of getting approval to restart. South Africa has the only nuclear power plant on the African continent, although Russia is building one in Egypt, and several other African nations are exploring the technology... With 57 reactors at 19 plants, France relies on nuclear power for nearly 70% of its electricity.
The article includes an interactive graphic that shows the growth in the world's nuclear capacity slowing down soon after the 1986 Chernobyl meltdown — with that capacity broken down by country. But it's still increased by roughly 50%.

Even Ukraine — the site of the accident — now "still relies heavily on nuclear plants to generate about half of its electricity," the article points out. But Germany "switched off its last three nuclear reactors in 2023."

An anonymous reader quotes a report from Wired: New gas projects linked to just 11 data center campuses around the US have the potential to create more greenhouse gases than the country of Morocco emitted in 2024. Emissions estimates from air permit documents examined by WIRED show that these natural gas projects -- which are being built to power data centers to serve some of the US's most powerful AI companies, including OpenAI, Meta, Microsoft, and xAI -- have the potential to emit more than 129 million tons of greenhouse gases per year. As tech companies race to secure massive power deals to build out hundreds of data centers across the country, these projects represent just the tip of the iceberg when it comes to the potential climate cost of the AI boom.

The infrastructure on this list of large natural gas projects reviewed by WIRED is being developed to largely bypass the grid and provide power solely for data centers, a trend known as behind-the-meter power. As data center developers face long waits for connections to traditional utilities, and amid mounting public resistance to the possibility of higher energy bills, making their own power is becoming an increasingly popular option. These projects have either been announced or are under construction, with companies already submitting air permit application materials with state agencies. [...] The emissions projections for the xAI and Microsoft projects, and all the others on WIRED's list, were pulled directly from publicly-available air permit documents in state databases as well as public air permit materials collected by both Cleanview and Oil and Gas Watch, a database maintained by the Environmental Integrity Project, an environmental enforcement nonprofit. Actual greenhouse gas emissions from power plants are usually lower than what's on their air permits. Air permit modeling is based on the scenario of a power plant constantly running at full capacity. That's rarely the reality for grid-connected power plants, as turbines go offline for maintenance or adjust to the ebbs and flows of customer demand.

"Permitted emission numbers represent a theoretical, conservative scenario, not the actual projected emissions," Alex Schott, the director of communications at Williams Companies, an oil and gas company that is building out three behind-the-meter power plants in Ohio for Meta, told WIRED in an email. Internal modeling done by the company, Schott added, shows that actual emissions could be "potentially two-thirds less than what's on paper." The projections involved, however, are still substantial. Even if the actual emissions from these power plants end up being half of the emissions numbers on the permits, they still could create more greenhouse gas emissions than the country of Norway emitted in 2024. This number is, according to the EPA, equivalent to the emissions from more than 153 average-sized natural gas plants. (WIRED's analysis does not include emissions from backup generators and turbines on the data center campuses themselves, which create smaller amounts of emissions.) Energy researcher Jon Koomey says the data center boom has created a shortage of the most efficient gas turbines, pushing some developers toward less efficient models that would need to run longer and produce more emissions. "[Data center operators'] belief is that the value being delivered by the servers is much, much more than the cost of running these inefficient power plants all the time," he said.

Michael Thomas, the founder of clean energy research firm Cleanview, has been tracking gas permits for data centers across the country. He calls behind-the-meter power "a crazy acceleration of emissions." He added: "It's almost like we thought we were on the downside of the Industrial Revolution, retiring coal and gas, and now we have a new hump where we're going to rise. That terrifies me in a lot of ways."

An anonymous reader quotes a report from Reuters: Tesla CEO Elon Musk said on Wednesday the EV maker plans to use Intel's next-generation 14A manufacturing process to make chips at its Terafab project, an advanced AI chip complex Musk has envisioned in Austin. The contract would mark Intel's first major customer for the technology, a breakthrough for the chipmaker which has struggled to stand up its contract manufacturing business essential for taking on top rival TSMC. Intel CEO Lip Bu Tan has said that the company would exit the chip manufacturing business altogether if it failed to secure an external customer.

Intel has previously said it was in discussions with large customers about 14A, but has not yet disclosed a major external customer. It declined to comment on Musk's remarks. [...] "Given that by the time Terafab scales up, 14A will be probably fairly mature or ready for prime time," Musk said. "14A seems like the right move, and we have a great relationship with Intel," he said. Ben Bajarin, head of technology consultancy Creative Strategies, said that Intel's 14A technology could "turn out to be a bigger deal for Intel than folks thought." "It's important to have multiple partners as early design partners to help clean the pipe and work through needed learnings at the leading edge. They will definitely have scale, so a great first non-Intel customer," Bajarin said.

Seaport Research Partners analyst Jay Goldberg said Musk's vote of confidence in Intel's technology outweighed the unknowns about the Terafab project. "Having a customer is more important than the timing," he said. Goldberg said that Musk's lofty estimates of how many chips its robots could one day require may or may not materialize, but even making chips for Tesla's existing businesses would be a significant win for Intel. "It's not equivalent to Apple or Nvidia" in terms of chip volumes, Goldberg said. "But it's a real customer. It can be real volumes."

Ancient Slashdot reader hwstar shares a report from The Conversation: For the first time ever, more than 50 nations will gather next week in Colombia to hash out how to wind down and end their dependence on coal, oil and gas. The history-making conference was planned before the Iran war. But this year's energy crisis has greatly raised the stakes. [...] Around 80% of the trapped oil was destined for the Asia-Pacific. Faced with dwindling supply, the region's governments are implementing emergency measures such as sending workers home, banning government travel, rationing fuel and cutting school hours. The problem is especially bad in the Pacific. Many island nations use diesel for power generation. In response, leaders declared a regional emergency.

[...] But the real difference from half a century ago is that fossil fuel alternatives are ready for prime time. Since the 1970s, the price of solar panels has fallen 99.9%, while the cost of wind has fallen 91% since 1984. Battery prices have fallen 99% since 1991. [...] This year's oil shock shows signs of creating an unplanned social tipping point -- a threshold for self-propelling change beyond which systems shift from one state to another. Climate scientists warn of climate tipping points which amplify feedback and accelerate warming. But social scientists also point to positive tipping points -- collective action that rapidly accelerates climate action.

[...] The routine burning of coal, oil and gas is the primary driver of the climate crisis. The world's highest court last year made clear nations have obligations to stop burning fossil fuels. But fossil fuels have barely been mentioned in 30 years of global climate negotiations, due in part to blocking efforts by big fossil fuel exporters and lobbyists. Frustrated by slow progress, a coalition of nations has bypassed global climate talks to discuss how to actually phase out fossil fuels. The first of these summits will take place next week. More than 50 nations will gather in Santa Marta, Colombia, to discuss a potential standalone treaty to manage fossil-fuel phaseout while protecting workers and financial systems.

alternative_right writes: A new technology has been proposed that could fundamentally solve the issue of smartphones overheating during high-spec gaming or extended video streaming. Researchers at KAIST have discovered the principle of processing signals using the minute vibrations of magnets (spin waves) instead of electrons. This method significantly reduces heat generation and power consumption while enabling instantaneous frequency switching within the several GHz range. This breakthrough is expected to pave the way for smart devices with less heat and longer battery life, as well as ultra-low-power, high-speed computing. Professor Kab-Jin Kim from the Department of Physics said: "This study is a case that proves we can implement and control the nonlinear dynamics of magnons -- the principle of information processing using magnetic vibrations -- in actual nano-devices, which had previously only been proposed in theory. It will serve as an important foundation for the development of a new information processing paradigm using spin waves instead of electrons."

The findings have been published in the journal Nature Communications.

Sony AI's autonomous table-tennis robot Ace has become the first robot to compete against top-level human players. Reuters reports: Ace, created by the Japanese company Sony's AI research division, is the first robot to attain expert-level performance in a competitive physical sport, one that requires rapid decisions and precision execution, the project's leader said. Ace did so by employing high-speed perception, AI-based control and a state-of-the-art robotic system. There have been various ping-pong-playing robots since 1983, but until now they were unable to rival highly skilled human competitors. Ace changed that with its performances against human elite-level and professional players in matches following the rules of the International Table Tennis Federation, the sport's governing body, and officiated by licensed umpires.

The project's goal was not only to compete at table tennis but to develop insights into how robots can perceive, plan and act with human-like speed and precision in dynamic environments. In matches detailed in the study, Ace in April 2025 won three out of five versus elite players and lost two matches against professional players, the top skill level in the sport. Sony AI said that since then Ace beat professional players in December 2025 and last month. "The success of Ace, with its perception system and learning-based control algorithm, suggests that similar techniques could be applied to other areas requiring fast, real-time control and human interaction -- such as manufacturing and service robotics, as well as applications across sports, entertainment and safety-critical physical domains," said Peter Durr, director of Sony AI Zurich and leader for Sony AI's project Ace.

The findings have been published in the journal Nature.

Google announced two new tensor processing units (TPUs) for the "agentic era," with separate processors dedicated to training and inference. "With the rise of AI agents, we determined the community would benefit from chips individually specialized to the needs of training and serving," Amin Vahdat, a Google senior vice president and chief technologist for AI and infrastructure, said in a blog post. Both chips will become available later this year. CNBC reports: After years of producing chips that can both train artificial intelligence models and handle inference work, Google is separating those tasks into distinct processors, its latest effort to take on Nvidia in AI hardware. [...] None of the tech giants are displacing Nvidia, and Google isn't even comparing the performance of its new chips with those from the AI chip leader. Google did say the training chip enables 2.8 times the performance of the seventh-generation Ironwood TPU, announced in November, for the same price, while performance is 80% better for the inference processor.

Nvidia said its upcoming Groq 3 LPU hardware will draw on large quantities of static random-access memory, or SRAM, which is used by Cerebras, an AI chipmaker that filed to go public earlier this month. Google's new inference chip, dubbed TPU 8i, also relies on SRAM. Each chip contains 384 megabytes of SRAM, triple the amount in Ironwood. The architecture is designed "to deliver the massive throughput and low latency needed to concurrently run millions of agents cost-effectively," Sundar Pichai, CEO of Google parent Alphabet, wrote in a blog post.

CATL unveiled a new wave of EV battery tech, "including a lighter battery pack rated for a 1,000-km (621-mile) driving range and an upgraded fast-charging battery that can go from 10 percent to 98 percent in under seven minutes," reports Interesting Engineering. From the report: The launches were made during a 90-minute event in Beijing ahead of the Beijing Auto Show, where automakers are expected to showcase next-generation EVs and connected technologies. CATL said its latest Qilin battery -- a high-energy-density pack often paired with nickel manganese cobalt (NMC) cells for long range and improved space efficiency -- can deliver a 1,000-km (621-mile) driving range. It is designed to deliver long range while reducing battery pack weight.

The company said the product is aimed at automakers facing tighter efficiency rules in China and other markets. It also rolled out an upgraded Shenxing battery -- CATL's fast-charging lithium iron phosphate (LFP) pack -- that targets one of the biggest barriers to EV adoption: charging time. CATL said the pack can recharge from 10 percent to 98 percent in less than seven minutes.

The new Shenxing battery marks a significant improvement over CATL's previous version, which charged from 5 percent to 80 percent in 15 minutes, according to Financial Times. [...] The company also announced plans to begin mass delivery of sodium-ion batteries in the fourth quarter. Sodium-ion technology is seen as a lower-cost alternative that could reduce dependence on lithium, cobalt, and nickel.

An anonymous reader quotes a report from Ars Technica: Framework has been selling and shipping its modular, repairable, upgradable Laptop 13 for five years now, and in that time, it has released six distinct versions of its system board, each using fresh versions of Intel and AMD processors (seven versions, if you count this RISC-V one). The laptop around those components has gradually gotten better, too. Over the years, Framework has added higher-resolution screens in both matte and glossy finishes, a slightly larger battery, and other tweaked components that refine the original design. But so far, all of those parts have been totally interchangeable, and the fundamentals of the Laptop 13 design haven't changed much.

That changes today with the Framework Laptop 13 Pro, which, despite its name, is less an offshoot of the original Laptop 13 and closer to a ground-up redesign. It includes new Core Ultra Series 3 chips (codenamed Panther Lake), Framework's first touchscreen, a new black aluminum color option, a larger battery, and other significant changes. And while it sacrifices some component compatibility with the original Laptop 13, displays and motherboards remain interchangeable, so Framework Laptop owners can buy the new Core Ultra board and owners of older Framework Laptop boards can pop one into a Pro to benefit from the new battery and screen. At 1.4kg (about 3 pounds), the Laptop 13 Pro is slightly heavier than the Laptop 13's 1.3kg, but it still stacks up well against the 14-inch M5 MacBook Pro (1.55kg, or 3.4 pounds).

The Framework Laptop Pro will start at $1,199 for a DIY edition with a Core Ultra 5 325 processor, and no RAM, SSD, or operating system. A prebuilt version with Ubuntu Linux installed will start at $1,499, and Windows 11 will cost another $100 on top of that. A Core Ultra X7 358H version starts at $1,599 for a DIY edition, and a "limited batch" Core Ultra X9 388H version starts at $1,799. A bare motherboard with the Core Ultra 5 325 starts at $449, while a Core Ultra X7 358H board will cost $799. Pre-orders are available now, and begin shipping in June.

The IEA says 2025 marked a turning point for global energy, with solar posting the largest growth ever seen for any energy source and helping carbon-free power outpace rising demand. The trend led the agency to declare that the world has entered the "Age of Electricity." Ars Technica reports: The IEA report covers energy use, including the electrical grid, transportation, home heating, and other forms of consumption. As such, it can track how some of those uses are shifting, as electric vehicles displace some gasoline use and heat pumps replace gas and oil heating. It also saw a more global trend: The demand for electricity grew at twice the rate of overall energy demand. All of these went into the conclusion that we're starting the Age of Electricity. In terms of specifics, the IEA saw electric vehicle demand rise by nearly 40 percent, with electric car sales being a quarter of the total of cars sold last year. While that's having a measurable effect on electricity demand, it remains relatively small at the moment. It's almost certain to be contributing to the size of the rise in oil use last year: 0.7 percent. In absolute terms, that's less than half the average rise of the previous decade.

[...] When it comes to supplying electrons for those alternatives, the central story is solar power. "The absolute increase of solar PV generation in 2025 is the largest ever observed for any source," the IEA says, "excluding years marked by rebounds from global economic shocks such as COVID-19." In other words, with nothing in particular driving the energy markets in 2025, Solar's growth was unprecedented. On its own, its growth covered a quarter of the rising demand for all forms of energy. If you limit it to electricity, increased solar production covered over two-thirds of the increased demand. Overall, solar generated over 2,700 terawatt-hours last year, more than double its output from three years earlier. It now accounts for over 8 percent of the world's total electricity production. Thirty individual countries installed at least a gigawatt of solar last year, and it is now the single largest grid source by capacity (though other sources still outproduce it at the moment).
