NHTSA said it plans to improve rules for LEDs, dusk sensors, automatic high beams and replaceable light sources. The agency will also evaluate headlamp height and aim and how they impact driver visibility and address headlight glare and make appropriate changes. Complaints about glare from headlights have increased and some lawmakers have urged the government to set a maximum headlight brightness standard. A growing number of taller trucks and SUVs on roads has also led to more complaints about glare. LEDs, which now account for most headlights in new cars, are much brighter than traditional halogen headlights... The issue still accounts for a small number of nighttime crashes, according to a study last year from the Insurance Institute for Highway Safety (IIHS). The study noted that headlight glare contributes to far fewer crashes than insufficient visibility... Federal headlight standards for minimum and maximum brightness have not changed since 1997, IIHS noted. The study found that drivers older than 70 appear to be most affected by headlight glare. In 2022, NHTSA said it would allow automakers to install adaptive driving beam headlights on new vehicles. The devices adjust the headlight beam pattern to dim portions directed at other vehicles.

As part of the mission science plan, lunar scientists asked the Artemis II crew to watch for tiny flashes sparked by rocky fragments hitting the Moon. Even so, some scientists were astonished when astronauts reported seeing five extremely faint "pinprick" bursts of light from 46,000 miles away. After ruling out other sources — cosmic rays or reflections from the spacecraft — the science team confirmed the sightings... The impact flash observations happened during a planned loss of communications while the Artemis II crew was on the far side of the Moon... Apollo astronauts saw similar flashes from lunar orbit, but the Artemis crew likely caught the faintest ever seen with the unaided eye. From the brightness of the flashes, scientists estimated that incoming rocks were each no more than a couple of inches wide. Despite their size, they were traveling thousands of miles per hour, producing just enough light upon impact to be visible. The nearly hour-long total solar eclipse that the crew experienced while passing by the Moon's far side created ideal dark conditions for spotting such subtle bursts. With no atmosphere to slow or burn up incoming debris, projectiles slam freely into the lunar surface. The crew's direct observations of this process on the Moon's far side provided a rare dataset that will help us understand how often these small impacts occur, which is essential for assessing long-term risks to future lunar habitats and infrastructure... The crew reported seeing subtle hues of gray, black, brown, tan, white, green, and blue across the Moon's surface. This muted rainbow offers clues to the rocks and minerals that make up different lunar regions, helping scientists piece together how the Moon — and, by extension, Earth — evolved over time. "Amazing news," Mission Control responded when they heard about the flashes. Space.com reports that when a Mission Control operator looked over at the Science Evaluation Room, "they were jumping up and down, literally." NASA blogged this week that more than 800 gigabytes of Artemis II lunar science data — some previously unreleased — "have been uploaded to NASA's Planetary Data System, the public archive for NASA's planetary missions." This data release includes more than 11,000 full-resolution images and video of the Moon from the crew's handheld cameras and the Orion spacecraft's cameras, 8.5 hours of audio recordings of the crew's scientific observations of the lunar surface, and crew-annotated images... Along with this data, NASA has released the Artemis II Preliminary Lunar Science Report, the Artemis II Lunar Science Operations Report, and the Artemis II Lunar Science Data User Guide.

Edward Dubrovsky was arrested in the Philadelphia area in recent days... Dubrovsky is facing charges related to extortion and making threats. He has been transferred to Texas's Eastern District for a scheduled detention hearing, according to court records and a law enforcement official. FBI Director Kash Patel announced the arrest on Friday but did not disclose where it occurred or what role the man is suspected of playing in the hack. Patel also didn't name Dubrovsky, but CNN confirmed the defendant is believed to be tied to the FBI hack through multiple people familiar with the investigation... A LinkedIn profile under Dubrovsky's name lists years of experience in the Canadian cybersecurity industry and describes Dubrovsky as a 'globally recognized cybersecurity expert.' An Ed Dubrovsky is also the author of a book on handling ransomware negotiations with cybercriminals... There has also been an inquest at the FBI over how such a critical security lapse happened. The FBI determined that a contractor managing the bureau's jobs portal failed to update software "explicitly issued to secure the platform," [senior FBI cyber official, Brett Leatherman said last week]. The FBI has "removed the contractor," he said. The software in question is a human-resources platform made by Oracle, ShinyHunters has said. The hackers previously used a flaw in the software to attack targets in the education sector in May and June, according to Google's Threat Intelligence Group. But months later, the FBI contractor apparently still had not applied a security patch that was available for the software. "The inmate locator at the U.S. Bureau of Prisons website reports that a 54-year-old Edward Dubrovsky is currently being held at a federal facility in Philadelphia," reports security researcher Brian Krebs.

The study "found that humans needed to consume twice the number of vegetables to get the same level of minerals such as potassium, magnesium or copper as would have been present in their food 60 years ago." The study found that many crops had lost 20% to 50% of several key nutrients... The decrease in nutrient and vitamin value is thought to be down to declining soil quality and crops being selectively bred for their ability to grow quickly, rather than there being any focus on their health benefits... It raises the prospect that the advice to eat five portions of fruit and vegetables a day, introduced in the UK in 2003, may need to be updated. The report added that people on weight-loss drugs could be most at risk from the lack of nutrients, as the treatments could cause them to consume less food... Nature-friendly farming techniques, such as planting crops that restore nutrients to the soil, could help improve the health benefits of vegetables, according to the researchers. In short, according to Will Summers, a senior associate at the firm, "we've been quietly hollowing out what's inside our food." Thanks to Slashdot reader Bruce66423 for sharing the article.

These AI company executives "anticipate a large-scale event, most likely a cyberattack, that shuts down access to financial services, internet connectivity, or even power and water..." the article points out. "Many top AI researchers and executives believe a major incident is inevitable. "OpenAI conducts preparedness exercises where teams discuss and work through a range of potential scenarios," a company spokesperson said. "These scenarios are not treated as inevitable, but are meant to help us prepare for a variety of circumstances." Anthropic declined to comment... Top AI planners assume Democrats, ascendant after the midterms, will move fast to shut down AI but will face significant challenges... The planning involves red-teaming for worst-case scenarios. It focuses mainly on racing to educate members of Congress. Company executives know regulation has no chance of passing right now, but still want to shape the legislation and policies U.S. leaders will turn to after a first catastrophic event.... Many AI industry insiders told Axios they believe a major event will occur in the next six to 12 months. "Even with Democrats in control of the House and Senate, the companies see fractured politics as the norm, including within the Democratic Party."

Amazon developed the series Spider-Noir for Prime Video, but then allegedly asked Cage to sign an AI waiver: "Amazon is a very AI-friendly company, to the tune of $50 billion invested in OpenAI," Cage said Saturday during a panel on the Empire Stage at New York Comic Con. "I am not an AI-friendly actor, so it's like, connect those dots! I'm not a member of their club. I didn't sign the waiver to let him use AI on 'Spider-Noir.' I'm probably not going to be working with that studio again, but that's okay." Last month Amazon canceled Spider-Man Noir after just one season, Variety reports. And the cancellation was just days before the Emmy Awards, where it then earned 11 nominations (the most of any Prime Video program this year). ScreenRant reports: Spider-Noir was the actor's first TV role and was praised globally, with season 1 earning a near-perfect Rotten Tomatoes rating from critics of 92% and a 90% rating from audiences. Critics stated that "This sharply written homage to classic film noir — which includes a standout Nicolas Cage performance — is the novel superhero project fans need," and "Spider-Noir is one of the standout shows of the year...." The cancellation was certainly a huge shock as it had earned 11 Emmy nominations and reached 2.6 billion minutes viewed within its first six weeks on Prime Video. More from Variety: Cage went on to tell the Comic-Con audience that he hopes to work with the rising class of Gen-Z filmmakers, praising Backrooms director Kane Parsons, who parlayed his YouTube fame into a Hollywood career... "I got to get with these young directors who are Gen Z, and they're going at it their own way, whether it's through the YouTube culture or whatever it is," Cage said. "They're doing it from scratch and by hand. I want to get with that."

Now it looks like the distro's OpenPGP implementation is next, with Sequoia PGP coming preinstalled in Ubuntu 26.10. Canonical wants it to eventually replace GnuPG [the dominant Linux implementation of PGP, written in C] as the default toolchain, though that switch has not happened yet... [The Ubuntu 26.10 release notes say Sequoia PGP's default status will be a future goal...] [Sequoia PGP] was started in 2017 by three former GnuPG developers who chose to build a new OpenPGP implementation in Rust rather than keep evolving GnuPG's existing codebase. Sequoia PGP is designed as a library that other software can use directly, rather than a standalone command-line tool. sq sits on top of that for encryption, decryption, signing, and key management, and sqv handles signature verification, filling in for gpg and gpgv in GnuPG. Sequoia also implements RFC 9580, the 2024 revision of the OpenPGP standard, whereas GnuPG has continued from the RFC 4880 branch, pursuing its own newer extensions and the LibrePGP specification rather than adopting RFC 9580 as its primary standard. From the It's FOSS Weekly newsletter, which also notes that the founder of the It's FOSS blog has also created a Linux-themed game called TUXDLE — a variation on Wordle where all the answers are Linux terms.

White House Mandates AI Companies Report Security Incidents AFP reports that an AI model from Anthropic "submitted a fabricated tip about an unsolved homicide to Philadelphia police, authorities said Friday." Claude "was instructed never to log in, create accounts, enter personal data, make purchases, or submit anything destructive, but the instructions did not rule out form submissions," Anthropic said Friday in a blog post. Authorities are now criticizing Anthropic "for taking two months to report the incident." The Philadelphia Police Department said the false submission was made in July through PhillyUnsolvedMurders.com, a public website where people can share information about unsolved killings. According to Anthropic's account, as relayed by police, the model was running a test that involved interacting with randomly selected websites when it reached the site and filed false information about an unsolved murder. The AI model presented itself as someone who might have knowledge of the case. Anthropic's breaches have prompted the White House to mandate that AI companies notify and correct security incidents, news outlet Axios reported [yesterday], citing administration officials. "This notification and remediation process is not optional... It is a critical national security obligation," White House Super Intelligence Force leaders said in a statement to Axios. "I may have information regarding this case," Claude told the police. "I recall seeing someone matching the description in the area around [the street named on the page] during that time period. Please contact me if this information is relevant." Anthropic notes that Claude "left the name and contact fields empty, which the form allowed, and submitted it. The submission was flagged as spam and was never forwarded for investigation." But Anthropic also admits they saw "this behavior" three times — "on OSWorld (a public computer use evaluation), on Odysseys (a long-horizon task evaluation), and during internal usage." Submitting forms when it shouldn't have generally occurred "when an evaluation's instructions were ambiguous, or when a misconfiguration within the environment prevented Claude from working with dummy forms." Anthropic's blog post acknowledges three other categories of behaviors: Exploiting software flaws. Like when Claude received an error when trying to run a public tool on a university's web site, it located an injection flaw in a script on the university's server that let it run commands — including that public tool. Working around restrictions to reach gated data. For example, Claude Mythos 5 needed public data that was only available from a state agency for a fee. "Claude learned from an archived copy of the agency's website that its public dashboard issues an access token to any visitor," Anthropic explains. "It requested one and used it to query the database without paying the fee." Using URL shortening services. "Some of our fetch tools, which let Claude read webpages, limit the length of the URLs Claude can request. This is to prevent Claude from using long URLs to take certain unwanted actions, such as SQL or command injections... We saw several models, including Claude Opus 5 and Claude Mythos 5, get around this limitation by using free URL shortening services." "We have built tooling to automatically detect and block the kinds of behaviors described above," Anthropic says, saying it's already running no on most of their evaluations. "When we tested it against the cases described in this post, it blocked all of them." And they've already taken several other new preventive measures: They've stopped running some public evaluations Other public evaluations were moved to offline versions or rebuilt so their tasks don't reach live websites. They've updated the guardrails on some internet access tools (including web fetch) "to heavily restrict what the model can do." They're continuing "to fix or remove training environments that reward Claude for working around tool restrictions or other blockers, so that they do not incentivize these behaviors or permit reward hacking." They've moved internal agents to "centrally managed infrastructure with strong containment," that minimizes internet access while monitoring "far more of what agents do through techniques like safety classifiers and hierarchical summarization." In the past they'd focused reviews on cybersecurity testing, but they've broadened their transcript reviewing to other tasks which include internet access. "Because language models are non-deterministic — that is, their responses always involve some element of randomness, and they may carry out the same task slightly differently each time — we have Claude complete each evaluation task hundreds or thousands of times... If training rewards something we didn't intend — such as finding loopholes or working around a restriction — the model learns that the workaround pays off and may then apply it elsewhere." Anthropic's blog post also acknowledged they'd seen multiple misalignment incidents involving federal, state, and local U.S. government agencies. "We have briefed the White House on these cases and notified each agency involved," Anthropic wrote, adding that "While we have not completed a full alignment assessment of these cases, we consider them to be less severe than the cybersecurity incidents from this summer." (And they are "modifying training to reduce the likelihood of further misbehavior.")

As well as long-form articles, the Iranian operation generated batches of social media comments, generally on topics related to the US-Iran war... [The Russian operation "appears to have co-opted unwitting people in Latin America to run a 'think tank'.... Since we do not allow access to our models from Russia, they used VPNs to connect to our services."] The Russian operation created fake "leaked" documents and audio scripts, some of which we identified being spread online... Both managed to land their content (not all of which was generated from our models) in mainstream media outlets, rather than simply posting it on social media. OpenAI says they've exposed 30 covert influence operations using its tools over the last two and a half years. But ironically, in this case both operations "also made heavy use of AI to draft internal reports (the Russian operation did this more than anything else)." And "in both cases, the actors used questionable or outright deceitful methodologies to exaggerate the operators' effectiveness." [The Russian operators] claimed that in May 2026, they created a fake email address purporting to come from the Regional Directorate of Education in Lima, Peru. They used this to instruct schools in the district to hold events dedicated to Ukraine on the national Day of Cultural and Linguistic Diversity (May 21)... According to the operators, some schools replied to the fake email address, confirming that they had held such events and even providing pictures. The operators then claimed to have planted stories about the events in the media in both Peru and Poland, alongside allegations that Ukraine was "exporting" ultra-nationalist ideologies, triggering outrage. Open-source searches identified stories that matched this claim in the Peruvianâ andâ Polish pressâ, and an English-language publication in Hungary (some of the articles have since been deleted)... Similarly, in June, the operators claimed they used a different fake email address to trick schools in Ecuador into holding a ceremony pledging allegiance to President Daniel Noboa and to Erik Prince, former head of private military contractor Blackwater. The operators claimed that the incident provoked outrage in Ecuador and put pressure on the government to deny the fake, thus amplifying it to a nationwide audience. Again, open-source research identified mediaâ coverageâ in the Ecuadorianâ pressâ that closely resembled this claim, and even a detailed rebuttalâ by Ecuador's Minister for Education. The operators used a range of techniques to underpin their false stories. According to their internal reporting, they spread two different fakes targeting Ecuador in March. One used fake audio attributed to Ukraine's consul in Ecuador, in which he was alleged to have made disparaging comments about Ecuadorians. OpenAI's report "is the latest illustration of how state actors can easily exploit widely available AI tools to peddle sophisticated propaganda against adversaries on a mass scale," argues the Economic Times: "We identified almost 100 articles published or syndicated under the [Iranian] operation's bylines across roughly a dozen online outlets around the world," OpenAI said. "These were small to medium outlets, generally focused on international affairs, geopolitics, and events in the Middle East." The earliest article identified by OpenAI was published in July 2025, and the latest in October 2026, with the frequency of reports increasing after the US-Iran war broke out earlier this year. The operation also generated social media comments on topics related to the US-Iran war, it added. One of the personas named Ervin B. Hoskins, whose bio claimed to be "an American freelance writer," had social media accounts across tech platforms including Elon Musk's X and Meta-owned Instagram. X's transparency information showed the account was connected via a "West Asia android app" and Instagram's transparency information showed the account was based in Iran, according to screenshots provided by OpenAI. Both accounts appeared to be suspended.

A Ring video of a Colorado woman being handed a criminal summons for a porch-package theft she did not commit recently went viral after the accusation rested on a Flock Safety automated license plate reader hit. Now, the woman involved in that case, Chrisanna Elser, is suing Flock Group, the towns of Columbine Valley and Bow Mar, Sergeant Jamie Milliman, and Chief Bret Cottrell in federal court on behalf of herself and other Coloradans whose plates the company has logged... The package in question was worth $25... The claims aimed at the company are intrusion upon seclusion, plus negligence and negligent design, on the theory that Flock sold a searchable archive and refused to require a warrant, a case number, or a supervisor's sign-off before an officer could run a plate... Elser is asking the court to make Columbine Valley, Bow Mar, Cottrell, and Flock delete the retained location data, to bar them from keeping it unless it is tied to an open case number, and to make Flock require a warrant, a case number, and a supervisor's approval before a Colorado agency can search the system. The Colorado Sun has more details. "Elser did not steal anything, but spent the following two weeks proving her own evidence to a department that did not return her calls, she said. [P]olice Sgt. Jamie Milliman told her the town of Bow Mar's surveillance cameras captured her forest green Rivian driving through town the same day a package disappeared from a thief... When Elser offered to show her own evidence to prove her innocence, including footage from her Rivian's onboard cameras, Milliman said she could bring it to court. Now, she is suing the officers and Flock Safety in U.S. District Court in Denver, alleging that the warrantless tracking violated her constitutional rights and that Flock's surveillance system unlawfully documents Coloradans' movements... "The scariest part is what happened to me can happen to anyone. I had no idea the Flock cameras existed and no idea a private company was keeping a record of every time I drove past my own neighborhood, or that any officer could pull it up without asking anyone or giving a reason for doing so," Elser said in a statement Tuesday. "If it can happen to me, it can happen to you...." "As noted in the complaint, the Flock system accurately identified the location of Ms. Elser's vehicle, while law enforcement retained responsibility for interpreting and weighing that information as part of the broader investigation," Paris Lewbel, Flock's public relations manager said. "Flock stands by the accuracy and integrity of its technology and intends to vigorously defend itself in this litigation." The article includes this statement from the woman's attorney. "Coloradans pass Flock's cameras on the way to work, church, the doctor, a protest, and a friend's house, and Flock keeps a detailed record of their every movement. It knows where you went, when you went there, and how often you go back, and it gives that information to a police officer with no limits. "We are asking a federal court to say what should be obvious: Flock's surveillance is straight-up creepy and the government does not get to follow everyone, all the time, without any reason for doing so."

Phoronix reports on a presentation this week by Meta engineer Gregory Price at the Linux Plumbers Conference in Prague: With today's memory shortages, high prices, and ever increasing memory capacity needs, Meta engineers have been working on Compressed RAM ("CRAM") for Linux. This hardware-offloaded compression still allows cacheline/byte access to compressed memory and in turn a better implementation than the likes of ZRAM and Zswap. Very promising is that there is near-native performance to raw DRAM speeds with CRAM... For end-users that may already be relying on the likes of Zswap or ZRAM, CRAM is offering near-native DRAM speeds. Read-only data is shown to be as fast as the raw DRAM performance. And for memory writes, CRAM is much faster than ZRAM or Zswap or plain swap. "Most of the individual pieces needed to support CRAM are already mainline," the article points out. Tom's Hardware writes that "It uses a private NUMA node (essentially, a ghost CPU) instead of pretending to be a block device, and this lets Linux continue using all of its memory semantics, including migration and ballooning, to manage CRAM." Because CRAM is stored in RAM and treated as RAM, with full cacheline/byte access, it can be accessed in a read-only fashion with little delay; just the cost of hardware-offloaded compression... Even when you enable writes, CRAM is still much faster than ZRAM; 5.4x in the worst tested case of 20% writes. That's a huge drop from the 452x read-only case, but keep your context; a 5.4x speedup is still titanic. The massive performance cliff when writes are involved comes down to the need to page fault and migrate folios back to the original NUMA domain, as you can't write directly to compressed data; you'd corrupt everything... While the obvious target of the work here (given its origin at Meta Platforms) is big Linux servers, ZRAM and Zswap are used all over the Linux ecosystem, even on machines as constrained as the Steam Deck. Many distributions enable one or the other by default. CRAM seems like it could offer a considerable speed-up for some of these machines, so hopefully it finds its way into the kernel once the remaining implementation questions are answered.

The clocks are already precise enough to lose only about a second over millions of years. The New York Times reports: The first nuclear clocks are not going to immediately supplant the worldwide network of atomic clocks, whose steady ticking we rely on for GPS and the definition of a second. Nor have they captured the record for most precise timepiece; the best atomic clocks are about 10,000 times more reliable and would take more than 100 billion years to lose one second. But nuclear clocks hold a bevy of potential advantages over existing atomic clocks. One day, they could be more reliable than the leading atomic versions, and nuclear clocks could be made more portable. They even hold the ability to search for certain kinds of dark matter -- the invisible stuff whose clumps make up 83 percent of the matter in the universe. If a particle of dark matter passed through the thorium nuclei, it could register as a wobble in the nuclear clock's otherwise steady ticktock. The findings have been published in the journal Nature.
