Last year was the hottest on record and the Earth is headed towards a global warming of 2.7 degrees, yet top fossil fuel and cement producers show a disregard for climate change and actively make things worse. From a report: A new Carbon Majors Database report found that just 57 companies were responsible for 80 percent of the global carbon dioxide emissions between 2016 and 2022. Thirty-eight percent of total emissions during this period came from nation-states, 37 percent from state-owned entities and 25 percent from investor-owned companies.

Nearly 200 parties adopted the 2015 Paris Agreement, committing to reduce greenhouse gas emissions. However, 58 of the 100 state- and investor-owned companies in the Carbon Majors Database have increased their production in the years since (The Climate Accountability Institute launched Carbon Majors in 2013 to hold fossil fuel producers accountable and is hosted by InfluenceMap). This number represents producers worldwide, including 87 percent of those assessed in Asia, 57 percent in Europe and 43 percent in North America.

It's not a clear case of things slowly turning around, either. The International Energy Agency found coal consumption increased by eight percent over the seven years to 8.3 billion tons -- a record high. The report names state-owned Coal India as one of the top three carbon dioxide producers. Russia's state-owned energy company Gazprom and state-owned oil firm Saudi Aramco rounded out the trio of worst offenders.

Google plans to destroy a trove of data that reflects millions of users' web-browsing histories, part of a settlement of a lawsuit that alleged the company tracked millions of users without their knowledge. WSJ: The class action, filed in 2020, accused Google of misleading users about how Chrome tracked the activity of anyone who used the private "Incognito" browsing option. The lawsuit alleged that Google's marketing and privacy disclosures didn't properly inform users of the kinds of data being collected, including details about which websites they viewed. The settlement details, filed Monday in San Francisco federal court, set out the actions the company will take to change its practices around private browsing. According to the court filing, Google has agreed to destroy billions of data points that the lawsuit alleges it improperly collected, to update disclosures about what it collects in private browsing and give users the option to disable third-party cookies in that setting.

The agreement doesn't include damages for individual users. But the settlement will allow individuals to file claims. Already the plaintiff attorneys have filed 50 in California state court. Attorney David Boies, who represents the consumers in the lawsuit, said the settlement requires Google to delete and remediate "in unprecedented scope and scale" the data it improperly collected. "This settlement is an historic step in requiring honesty and accountability from dominant technology companies," Boies said.

"Researchers have successfully transformed CO2 into methanol," reports SciTechDaily, "by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels." Tara LeMercier, a PhD student who carried out the experimental work at the University of Nottingham, School of Chemistry, said: "We measured the current generated by light and used it as a criterion to judge the quality of the catalyst. Even without copper, the new form of carbon nitride is 44 times more active than traditional carbon nitride. However, to our surprise, the addition of only 1 mg of copper per 1 g of carbon nitride quadrupled this efficiency. Most importantly the selectivity changed from methane, another greenhouse gas, to methanol, a valuable green fuel."

Professor Andrei Khlobystov, School of Chemistry, University of Nottingham, said: "Carbon dioxide valorization holds the key for achieving the net-zero ambition of the UK. It is vitally important to ensure the sustainability of our catalyst materials for this important reaction. A big advantage of the new catalyst is that it consists of sustainable elements — carbon, nitrogen, and copper — all highly abundant on our planet." This invention represents a significant step towards a deep understanding of photocatalytic materials in CO2 conversion. It opens a pathway for creating highly selective and tuneable catalysts where the desired product could be dialed up by controlling the catalyst at the nanoscale.
"The research has been published in the Sustainable Energy & Fuels journal of the Royal Society of Chemistry."

"If you want to see what the cutting edge of next-gen clean energy innovation looks like, it'd be hard to find a place better than Texas," Bill Gates wrote recently on his blog," saying "amazing companies" are breaking ground across the state. "Each one represents a huge boon for the local economy, America's energy security, and the fight against climate change." The world is undergoing an energy transition right now, fueled by the development and deployment of new clean energy technologies. The pace of innovation at the heart of this transition is happening faster than many people (including me!) dared hope. The progress makes me optimistic about the future — and excited about the role that American communities will play, especially in places like Texas.

Breakthrough Energy and I have invested more than $130 million into Texas-based entrepreneurs, institutions, and projects. It's a big bet, but it's one I'm confident in. Why? Because of the people. Nearly half a million Texans work in the oil and gas industry, and their skills are directly transferrable to next-generation industries. This workforce will help form the backbone of the world's new clean energy economy, and it will cement Texas's energy leadership for generations to come.

Many of the companies I'm seeing on this trip already employ or plan to employ oil and gas workers. One of those companies is Infinium, which is working on next-generation clean fuels for trucks, ships, and even planes. I'm visiting their first demonstration plant in Corpus Christi, where they're turning waste CO2 and renewable energy into electrofuels — or eFuels — for trucks. They've already signed a deal with Amazon, and sometime soon, if you live in the area, you might get a delivery supported by Infinium eDiesel. The key to Infinium's approach is that their fuels can be dropped into existing engines... I'm especially excited about the work they're doing on sustainable aviation fuel, or SAF — which could reduce emissions from air travel by as much as 90 percent, according to company estimates. Infinium is in the process of converting an old gas-to-liquid plant in West Texas into a new facility that will increase the company's capacity for producing eFuels ten-fold. Breakthrough Energy's Catalyst program has invested in this first-of-its-kind plant, and I can't wait to see it when it's done.

Another company I'll see is Mars Materials. They're a Breakthrough Energy Fellows project working on a different way to reuse CO2. The company is developing a clever technique for turning captured carbon into one of the key components in carbon fiber, an ultra-light, ultra-strong material that is used in everything from clothing to car frames... The Mars Materials team relocated from California to Texas in part because of the skilled oil and gas talent that they could access in the state, and they aren't the first Breakthrough Energy company to do that. I'm going to check out their lab, where their scientists are hard at work optimizing the conversion process.
Both companies assume abundant CO2, Gates writes, but "fortunately for them, Texas is also in the process of becoming a capital for direct air capture... A recent study found that Texas has the greatest DAC deployment potential in the country and could create as many as 400,000 jobs by 2050." Already a direct air capture "hub" in Kingsville, Texas is expected to create 2,500 jobs over the next five years, while Houston has been selected as the site for one of America's seven Regional Clean Hydrogen Hubs.

"If you want to catch a glimpse of our country's clean energy future," Gates writes, "you should head on down to the Lone Star State."

Lyle Smith reports via StorageReview.com: Proxmox has introduced a new import wizard for Proxmox Virtual Environment (VE), aiming to simplify the migration process for importing VMware ESXi VMs. This new feature comes at an important time in the industry, as it aims to ease the transition for these organizations looking to move away from VMware's vSphere due to high renewal costs.

The new import wizard is integrated into Proxmox VE's existing storage plugin system, allowing for direct integration into the platform's API and web-based user interface. It offers users the ability to import VMware ESXi VMs in their entirety, translating most of the original VM's configuration settings to Proxmox VE's configuration model (all while minimizing downtime). Currently, the import wizard is in a technical preview state, having been added during the Proxmox VE 8.2 development cycle. Although it is still under active development, early reports suggest the wizard is stable and holds considerable promise for future enhancements, including the planned addition of support for other import sources like OVF/OVA files. [...]

This tool represents Proxmox's commitment to providing accessible, open-source virtualization solutions. By leveraging the official ESXi API and implementing a user space filesystem with optimized read-ahead caching in Rust (a safe, fast, and modern programming language ideal for system-level tasks), Proxmox aims to ensure that this new feature can be integrated smoothly into its broader ecosystem.

The BBC says it has stopped using AI to promote Doctor Who after receiving complaints from viewers. Deadline reports: The BBC's marketing teams used the tech "as part of a small trial" to help draft some text for two promotional emails and mobile notifications, according to its complaints website, which was intended to highlight Doctor Who programming on the BBC. But the corporation received complaints over the reports that it was using generative AI, it added. "We followed all BBC editorial compliance processes and the final text was verified and signed-off by a member of the marketing team before it was sent," the BBC said. "We have no plans to do this again to promote Doctor Who."

The decision to stop promoting via generative AI represents a u-turn from the BBC, who said at the time of announcement that "generative AI offers a great opportunity to speed up making the extra assets to get more experiments live for more content that we are trying to promote." At the time, the BBC didn't mention that this would be the only time it uses the technology for Doctor Who promotion. Doctor Who will launch in May on the BBC and, for the first time, Disney+. A new trailer was unveiled last week.

Slashdot reader sciencehabit shared this report from Science magazine: Nurturing a growing fetus requires a series of profound physical, hormonal, and chemical changes that may rewire every major organ in the body and can cause serious health complications such as hypertension and preeclampsia. But does being pregnant actually take years off your life...?

Today in Cell Metabolism, scientists report that the stress of pregnancy can cause a person's biological age to increase by up to 2 years — a trend that may reverse itself in the months that follow. In some cases, the authors write, those who breastfeed their children after giving birth may end up biologically "younger" than during early pregnancy. The finding represents yet another piece of "compelling" evidence that events during and after pregnancy can have far-reaching health consequences, says Elizabeth Bertone-Johnson, an epidemiologist at the University of Massachusetts Amherst who wasn't involved in the new study...

The discovery that biological aging isn't necessarily a linear process "came as a real surprise," says Kieran O'Donnell, a perinatal researcher at the Yale School of Medicine... But blood samples from 68 participants, collected 3 months after giving birth, revealed a dramatic about-face. Although being pregnant had initially aged their cells between 1 and 2 years, says O'Donnell, their biological age now appeared to be 3 to 8 years younger than it had been during early pregnancy — with different epigenetic clocks algorithms providing slightly bigger or smaller estimates.

The Coalition for App Fairness, an industry body that represents Epic, Spotify, Match Group and Proton among others, issued the following statement following the U.S. announcing it had sued Apple: "With today's announcement, the Department of Justice is taking a strong stand against Apple's stranglehold over the mobile app ecosystem, which stifles competition and hurts American consumers and developers alike. The DOJ complaint details Apple's long history of illegal conduct -- abusing their App Store guidelines and developer agreements to increase prices, extract exorbitant fees, degrade user experiences, and choke off competition. The DOJ joins regulators around the world, who have recognized the many harms of Apple's abusive behavior and are working to address it. As this case unfolds in the coming years more must be done now to end the anticompetitive practices of all mobile app gatekeepers. It remains imperative that Congress pass bipartisan legislation, like the Open App Markets Act, to create a free and open mobile app marketplace."

An anonymous reader quotes a report from TechCrunch: In India, a government-run agency will now monitor and undertake fact-checking for government related matters on social media even as tech giants expressed grave concerns about it last year. The Ministry of Electronics and IT on Wednesday wrote in a gazette notification that it is amending the IT Rules 2021 to cement into law the proposal to make the fact checking unit of Press Information Bureau the dedicated arbiter of truth for New Delhi matters. Tech companies as well as other firms that serve more than 5 million users in India will be required to "make reasonable efforts" to not display, store, transmit or otherwise share information that deceives or misleads users about matters pertaining to the government, the IT ministry said. India's move comes just weeks ahead of the general elections in the country. Relying on a government agency such as the Press Information Bureau as the sole source to fact-check government business without giving it a clear definition or providing clear checks and balances "may lead to misuse during implementation of the law, which will profoundly infringe on press freedom," Asia Internet Coalition, an industry group that represents Meta, Amazon, Google and Apple, cautioned last year.

Meanwhile, comedian Kunal Kamra, with support from the Editors Guild of India, cautioned that the move could create an environment that forces social media firms to welcome "a regime of self-interested censorship."

The European Union has agreed to launch four Galileo navigation satellites on SpaceX's Falcon 9 rocket at a 30 percent premium over the standard launch price. Ars Technica reports: According to Politico, the security agreement permits staff working for the EU and European Space Agency to have access to the launch pad at all times and, should there be a mishap with the mission, the first opportunity to retrieve debris. With the agreement, final preparations can begin for two launches of two satellites each, on the Falcon 9 rocket from Florida. These Galileo missions will occur later this year. The satellites, which each weigh about 700 kg, will be launched into an orbit about 22,000 km above the planet.

The heightened security measures are due to the proprietary technology incorporated into the satellites, which cost hundreds of millions of euros to build; they perform a similar function to US-manufactured Global Positioning System satellites. The Florida launches will be the first time Galileo satellites, which are used for civilian and military purposes, have been exported outside of European territory. Due to the extra overhead related to the national security mission, the European Union agreed to pay 180 million euros for the two launches, or about $196 million. This represents about a 30 percent premium over the standard launch price of $67 million for a Falcon 9 launch. Over the past two years, the European Space Agency (ESA) had to rely on SpaceX for several launches, including significant projects like the Euclid space telescope and other ESA satellites, due to the cessation of collaborations with Roscosmos after the invasion of Ukraine and delays in the Ariane 6 rocket's development. With the Ariane 5 retired and no immediate replacement, Europe's access to space was compromised.

That said, the Ariane 6 is working towards a launch window in the coming months, promising a return to self-reliance for ESA with a packed schedule of missions ahead.

Haje Jan Kamps writes via TechCrunch: Artificial General Intelligence (AGI) -- often referred to as "strong AI," "full AI," "human-level AI" or "general intelligent action" -- represents a significant future leap in the field of artificial intelligence. Unlike narrow AI, which is tailored for specific tasks (such as detecting product flaws, summarize the news, or build you a website), AGI will be able to perform a broad spectrum of cognitive tasks at or above human levels. Addressing the press this week at Nvidia's annual GTC developer conference, CEO Jensen Huang appeared to be getting really bored of discussing the subject -- not least because he finds himself misquoted a lot, he says. The frequency of the question makes sense: The concept raises existential questions about humanity's role in and control of a future where machines can outthink, outlearn and outperform humans in virtually every domain. The core of this concern lies in the unpredictability of AGI's decision-making processes and objectives, which might not align with human values or priorities (a concept explored in depth in science fiction since at least the 1940s). There's concern that once AGI reaches a certain level of autonomy and capability, it might become impossible to contain or control, leading to scenarios where its actions cannot be predicted or reversed.

When sensationalist press asks for a timeframe, it is often baiting AI professionals into putting a timeline on the end of humanity -- or at least the current status quo. Needless to say, AI CEOs aren't always eager to tackle the subject. Predicting when we will see a passable AGI depends on how you define AGI, Huang argues, and draws a couple of parallels: Even with the complications of time-zones, you know when new year happens and 2025 rolls around. If you're driving to the San Jose Convention Center (where this year's GTC conference is being held), you generally know you've arrived when you can see the enormous GTC banners. The crucial point is that we can agree on how to measure that you've arrived, whether temporally or geospatially, where you were hoping to go. "If we specified AGI to be something very specific, a set of tests where a software program can do very well -- or maybe 8% better than most people -- I believe we will get there within 5 years," Huang explains. He suggests that the tests could be a legal bar exam, logic tests, economic tests or perhaps the ability to pass a pre-med exam. Unless the questioner is able to be very specific about what AGI means in the context of the question, he's not willing to make a prediction. Fair enough.

An anonymous reader quotes a report from TechCrunch: Google today is sharing more details about the fees that will accompany its plan to comply with Europe's new Digital Markets Act (DMA), the new regulation aimed at increasing competition across the app store ecosystem. While Google yesterday pointed to ways it already complied with the DMA -- by allowing sideloading of apps, for example -- it hadn't yet shared specifics about the fees that would apply to developers, noting that further details would come out this week. That time is now, as it turns out.

Today, Google shared that there will be two fees that apply to its External offers program, also announced yesterday. This new program allows Play Store developers to lead their users in the EEA outside their app, including to promote offers. With these fees, Google is going the route of Apple, which reduced its App Store commissions in the EU to comply with the DMA but implemented a new Core Technology Fee that required developers to pay 0.50 euros for each first annual install per year over a 1 million threshold for apps distributed outside the App Store. Apple justified the fee by explaining that the services it provides developers extend beyond payment processing and include the work it does to support app creation and discovery, craft APIs, frameworks and tools to support developers' app creation work, fight fraud and more.

Google is taking a similar tactic, saying today that "Google Play's service fee has never been simply a fee for payment processing -- it reflects the value provided by Android and Play and supports our continued investments across Android and Google Play, allowing for the user and developer features that people count on," a blog post states. It says there will now be two fees that accompany External Offers program transactions:

- An initial acquisition fee, which is 10% for in-app purchases or 5% for subscriptions for two years. Google says this fee represents the value that Play provided in facilitating the initial user acquisition through the Play Store.
- An ongoing services fee, which is 17% for in-app purchases or 7% for subscriptions. This reflects the "broader value Play provides users and developers, including ongoing services such as parental controls, security scanning, fraud prevention, and continuous app updates," writes Google.

Of note, a developer can opt out of the ongoing services and corresponding fees, if the user agrees, after two years. Users who initially installed the app believe they'll have services like parental controls, security scanning, fraud prevention and continuous app updates, which is why opting out requires user consent. Although Google allows the developer to terminate this fee, those ongoing services will no longer apply either. Developers, however, will still be responsible for reporting transactions involving those users who are continuing to receive Play Store services.

"Linux gained from 3% to 4% in 8 months," writes longtime Slashdot reader bobdevine. Linuxiac reports: According to the latest data from StatCounter, a leading web traffic analysis tool, Linux's market share has reached 4.03%. At first glance, the number might seem modest, but it represents a significant leap. Let's break it down. It took Linux 30 years to secure a 3% share of desktop operating systems, a milestone reached last June. Impressively, the open-source operating system has surged by an additional 1% in the last eight months.

An anonymous reader quotes a report from NPR: ExxonMobil faces dozens of lawsuits from states and localities alleging the company lied for decades about its role in climate change and the dangers of burning fossil fuels. But now, ExxonMobil is going on the offensive with a lawsuit targeting investors who want the company to slash pollution that's raising global temperatures. Investors in publicly-traded companies like ExxonMobil try to shape corporate policies by filing shareholder proposals that are voted on at annual meetings. ExxonMobil says it's fed up with a pair of investor groups that it claims are abusing the system by filing similar proposals year after year in an effort to micromanage its business.

ExxonMobil's lawsuit points to growing tensions between companies and activist investors calling for corporations to do more to shrink their climate impact and prepare for a hotter world. Interest groups on both sides of the case say it could unleash a wave of corporate litigation against climate activists. It is happening at a time when global temperatures continue to rise, and corporate analysts say most companies aren't on track to meet targets they set to reduce their heat-trapping emissions. "Exxon is really upping the ante here in a big way by bringing this case," says Josh Zinner, chief executive of an investor coalition called the Interfaith Center on Corporate Accountability, whose members include a defendant in the ExxonMobil case. "Other companies could use this tactic not just to block resolutions," Zinner says, "but to intimidate their shareholders from even bringing these [climate] issues to the table."

ExxonMobil said in an email that it is suing the investor groups Arjuna Capital and Follow This because the U.S. Securities and Exchange Commission (SEC) isn't enforcing rules governing when investors can resubmit shareholder proposals. A court is the "the right place to get clarity on SEC rules," ExxonMobil said, adding that the case "is not about climate change." Other corporations are watching ExxonMobil's case, says Charles Crain, a vice president at the National Association of Manufacturers, which represents ExxonMobil and other industrial companies. "If companies are decreasingly able to get the SEC to allow them to exclude proposals that are obviously politically motivated, then the next question is, well, can the courts succeed where the SEC has failed -- or, more accurately, not even tried?," Crain says. "The shareholder proposal from Arjuna and Follow This called for ExxonMobil to cut emissions faster from its own operations and from its supply chain, including the pollution that's created when customers burn its oil and natural gas," notes NPR. "That indirect pollution, known as Scope 3 emissions, accounts for 90% of ExxonMobil's carbon footprint."

"ExxonMobil says it is committed to cutting emissions from its operations. But the idea that activist investors like Arjuna and Follow This can quickly push the company out of the oil and gas business with new climate policies is 'simplistic and against the interests of the vast majority of ExxonMobil shareholders,' the company said in a court filing in Texas." The company added that while shareholders are entitled to submit proposals, they don't have "an unlimited right to put forth any proposal to do anything."

"Their intent is to advance their agenda rather than creating long-term value for shareholders," ExxonMobil said of Arjuna and Follow This.

Intel's previously-unannounced Intel 10A (analogous to 1nm) will enter production/development in late 2027, marking the arrival of the company's first 1nm node, and its 14A (1.4nm) node will enter production in 2026. The company is also working to create fully autonomous AI-powered fabs in the future. Tom's Hardware: Intel's Keyvan Esfarjani, the company's EVP and GM and Foundry Manufacturing and Supply, held a very insightful session that covered the company's latest developments and showed how the roadmap unfolds over the coming years. Here, we can see two charts, with the first outlining the company's K-WSPW (thousands of wafer starts per week) capacity for Intel's various process nodes. Notably, capacity typically indicates how many wafers can be started, but not the total output -- output varies based on yields. You'll notice there isn't a label for the Y-axis, which would give us a direct read on Intel's production volumes. However, this does give us a solid idea of the proportionality of Intel's planned node production over the next several years.

Intel did not specify the arrival date of its coming 14A node in its previous announcements, but here, the company indicates it will begin production of the Intel 14A node in 2026. Even more importantly, Intel will begin production/development of its as-yet-unannounced 10A node in late 2027, filling out its roster of nodes produced with EUV technology. Intel's 'A' suffix in its node naming convention represents Angstroms, and 10 Angstroms converts to 1nm, meaning this is the company's first 1nm-class node. Intel hasn't shared any details about the 10A/1nm node but has told us that it classifies a new node as at least having a double-digit power/performance improvement. Intel CEO Pat Gelsinger has told us the cutoff for a new node is around a 14% to 15% improvement, so we can expect that 10A will have at least that level of improvement over the 14A node. (For example, the difference between Intel 7 and Intel 4 was a 15% improvement.)

Apple researchers have unveiled a new AI tool called "Keyframer," (PDF) which harnesses the power of large language models (LLMs) to animate static images through natural language prompts. From a report: This novel application, detailed in a new research paper published on arxiv.org, represents a giant leap in the integration of artificial intelligence into the creative process -- and it may also hint at what's to come in newer generations of Apple products such as the iPad Pro and Vision Pro. The research paper, titled "Keyframer: Empowering Animation Design using Large Language Models," explores uncharted territory in the application of LLMs to the animation industry, presenting unique challenges such as how to effectively describe motion in natural language.

Imagine this: You're an animator with an idea that you want to explore. You've got static images and a story to tell, but the thought of countless hours bending over an iPad to breathe life into your creations is, well, exhausting. Enter Keyframer. With just a few sentences, those images can begin to dance across the screen, as if they've read your mind. Or rather, as if Apple's large language models (LLMs) have. Keyframer is powered by a large language model (in the study, they use GPT-4) that can generate CSS animation code from a static SVG image and prompt. "Large language models have the potential to impact a wide range of creative domains, but the application of LLMs to animation is under-explored and presents novel challenges such as how users might effectively describe motion in natural language," the researchers explain.

Silicon Valley institution Y Combinator has released a new list of 20 types of startups it wants to join its accelerator program -- calling for applications in sectors like AI-powered robotics, space and defense technology. From a report: Y Combinator, YC for short, updates the list periodically, depending on what kinds of startups it sees gaining traction and where it thinks there's opportunity. This update, released in a blog post Wednesday, represents the biggest overhaul to its "requests for startups" since 2018. In a blog post Wednesday, YC Managing Director Dalton Caldwell described the requests as "ideas we'd want to see made real, in spaces that we believe will be important in the coming decades." The result is a window into the larger trends in the world of venture capital.

The first idea on YC's list is applying machine learning to robotics. "For decades, everyone has known that robots are the future, as any science fiction novel will show," YC partners wrote in the blog post. Now, advances around artificial intelligence are making the technology more useful, particularly in industrial settings. It listed autonomous tractors and infrastructure inspection robots as examples.

Shell once announced it would build 48 new Hydrogen fueling stations for light-duty vehicles in California, according to the blog Hydrogen Insights. But then in September, Shell told the site they'd "discontinued" that plan.

And last month the Inside EVs blog noted that in all of 2023, just 2,968 hydrogen cars were sold "in the United States — and by that, we mean in California, where the series-produced models are available." That's according to data from the Hydrogen Fuel Cell Partnership — admittedly a 10% increase from 2022's sales figure of 2,707 — but with both numbers lower than 2021's sales of 3,341. "The overall cumulative sales of hydrogen fuel cell vehicles exceeded 17,940 as of the end of the quarter (not counting vehicles removed from use), which is 20% more than a year ago."

Then this week Shell said it will "no longer be operating" any light-duty hydrogen fuelling stations in the U.S., and will close all seven of its California pumping stations immediately. (Three in San Francisco, one in Berkeley, one in San Jose, and two in the Sacramento area.) Inside EVs says Shell's move "represents another blow to the struggling hydrogen car market in the only state where the fuel is widely available at all." Shell had, until recently, operated seven of the 55 total retail hydrogen stations in California, per the Hydrogen Fuel Cell Partnership (H2FCP). That makes this a blow, but not apocalyptic news for the (small) hydrogen community....

In the letter announcing the closure, Shell Hydrogen Vice President Andrew Beard said they were shutting them down "due to hydrogen supply complications and other external market factors." It's not hard to see what Beard is referencing here... Hydrogen Insight reports that this shortage has been disrupting stations since August 13...

Some are also down for repairs, as many hydrogen stations suffer from serious reliability issues. Iwatani, a Japanese gas company that is one of the two largest names in American hydrogen filling stations, is currently suing the company that provided the core technology for its stations. In a court filing viewed by Hydrogen Insight, Iwatini alleges that its provider did not test its equipment in a real-world commercial scenario, hid defects, and misled the company. It is, in short, a big mess.

All of this makes the future of hydrogen fuel-cell vehicles in the United States even more uncertain. The technology has struggled to catch on, as the stations and their fuel remain expensive. Though hydrogen car manufacturers usually include a large amount of free fuel in the purchase of a vehicle, once that runs out consumers are left with eye-watering prices from stations that are often broken, out of fuel, or swarmed with long lines. It's why used hydrogen cars are so cheap, and why they still aren't a good deal.

Few companies can make a better case for it than Shell, though, as the cheapest way to produce hydrogen involves a lot of natural gas. Its proximity to the fossil-fuel industry was supposed to make it cheaper, and provide incentive for robust fueling infrastructure. That hasn't played out, though, and one of the largest oil giants is throwing in the towel. If even a fossil giant like Shell can't justify investing in the future of light-duty hydrogen infrastructure, we're not sure who can.

An anonymous reader shared this report from the Washington Post: A California state lawmaker introduced a bill on Thursday aiming to force companies to test the most powerful artificial intelligence models before releasing them — a landmark proposal that could inspire regulation around the country as state legislatures increasingly tackle the swiftly evolving technology.

The new bill, sponsored by state Sen. Scott Wiener, a Democrat who represents San Francisco, would require companies training new AI models to test their tools for "unsafe" behavior, institute hacking protections and develop the tech in such a way that it can be shut down completely, according to a copy of the bill. AI companies would have to disclose testing protocols and what guardrails they put in place to the California Department of Technology. If the tech causes "critical harm," the state's attorney general can sue the company.

Wiener's bill comes amid an explosion of state bills addressing artificial intelligence, as policymakers across the country grow wary that years of inaction in Congress have created a regulatory vacuum that benefits the tech industry. But California, home to many of the world's largest technology companies, plays a singular role in setting precedent for tech industry guardrails. "You can't work in software development and ignore what California is saying or doing," said Lawrence Norden, the senior director of the Brennan Center's Elections and Government Program... Wiener says he thinks the bill can be passed by the fall.
The article notes there's now 407 AI-related bills "active in 44 U.S. states (according to an analysis by an industry group called BSA the Software Alliance) — with several already signed into law. "The proliferation of state-level bills could lead to greater industry pressure on Congress to pass AI legislation, because complying with a federal law may be easier than responding to a patchwork of different state laws."

Even the proposed California law "largely builds off an October executive order by President Biden," according to the article, "that uses emergency powers to require companies to perform safety tests on powerful AI systems and share those results with the federal government. The California measure goes further than the executive order, to explicitly require hacking protections, protect AI-related whistleblowers and force companies to conduct testing."

They also add that as America's most populous U.S. state, "California has unique power to set standards that have impact across the country." And the group behind last year's statement on AI risk helped draft the legislation, according to the article, though Weiner says he also consulted tech workers, CEOs, and activists. "We've done enormous stakeholder outreach over the past year."

The U.S. Environmental Protection Agency (EPA) today unveiled new, stricter limits for PM2.5 (particulate smaller than 2.5 micrometers in diameter), commonly referred to as soot. As NPR notes, these particles are are "one of the deadliest types of air pollution." From the report: The agency lowered the allowable limit for annual PM2.5 levels from 12 micrograms per cubic meter to 9. That's a "significant reduction," says Regan Patterson, an air pollution expert at the University of California, Los Angeles. "The science is clear," says EPA Administrator Michal Regan. "Soot pollution is one of the most dangerous forms of air pollution and is linked to a range of serious and potentially deadly illnesses, including asthma and heart attacks."

The new standard represents the first tightening of the rules since 2012, but states will have several years to reach the new limits. The EPA left the daily limits on PM2.5 pollution unchanged, at 35 micrograms per cubic meter, saying the same efforts that will reduce pollution under the revised annual standard will drive down short-term pollution exposures as well. Decades of research have demonstrated that tiny particles are dangerous to people's health at nearly any concentration. The sources vary: fossil fuel combustion, agriculture, and industrial processes all add to the load, as does wildfire smoke and dust.

In aggregate, the tiny particles drive millions of premature deaths worldwide each year. The EPA estimates that the new, tighter standards will prevent about 4,500 premature deaths a year by 2032 in the U.S. and prevent about 800,000 asthma-related emergency visits. It estimates the lower pollution exposures could reduce healthcare costs by about $46 billion by that time.
