It's not dark matter, writes Space.com. But astronomers have discovered "a vast tendril of hot gas linking four galaxy clusters and stretching out for 23 million light-years, 230 times the length of our galaxy. "With 10 times the mass of the Milky Way, this filamentary structure accounts for much of the universe's 'missing matter,' the search for which has baffled scientists for decades...." [I]t is "ordinary matter" made up of atoms, composed of electrons, protons, and neutrons (collectively called baryons) which make up stars, planets, moons, and our bodies. For decades, our best models of the universe have suggested that a third of the baryonic matter that should be out there in the cosmos is missing. This discovery of that missing matter suggests our best models of the universe were right all along. It could also reveal more about the "Cosmic Web," the vast structure along which entire galaxies grew and gathered during the earlier epochs of our 13.8 billion-year-old universe.... The newly observed filament isn't just extraordinary in terms of its mass and size; it also has a temperature of a staggering 18 million degrees Fahrenheit (10 million degrees Celsius). That's around 1,800 times hotter than the surface of the sun... The team's research was published on Thursday (June 19) in the journal Astronomy & Astrophysics. Models of the cosmos (including the standard model of cosmology) "have long posited the idea that the missing baryonic matter of the universe is locked up in vast filaments of gas stretching between the densest pockets of space..." the article points out. But now thanks to Suzaku, a Japan Aerospace Exploration Agency (JAXA) satellite, and the European Space Agency's XMM-Newton, "a team of astronomers has for the first time been able to determine the properties of one of these filaments, which links four galactic clusters in the local universe." Team leader Konstantinos Migkas (of the Netherlands' Leiden Observatory) explained the significance of their finding. "For the first time, our results closely match what we see in our leading model of the cosmos — something that's not happened before." "It seems that the simulations were right all along."

ScienceDaily reports: Researchers from MIT and Scripps have unveiled a promising new HIV vaccine approach that generates a powerful immune response with just one dose. By combining two immune-boosting adjuvants alum and SMNP the vaccine lingers in lymph nodes for nearly a month, encouraging the body to produce a vast array of antibodies. This one-shot strategy could revolutionize how we fight not just HIV, but many infectious diseases. It mimics the natural infection process and opens the door to broadly neutralizing antibody responses, a holy grail in vaccine design. And best of all, it's built on components already known to medicine. Thanks to Slashdot reader alternative_right for sharing the news.

In April Anthorpic introduced a new AI trick: multiple Claude agents combine for a "Research" feature that can "search across both your internal work context and the web" (as well as Google Workspace "and any integrations...") But a recent Anthropic blog post notes this feature "involves an agent that plans a research process based on user queries, and then uses tools to create parallel agents that search for information simultaneously," which brings challenges "in agent coordination, evaluation, and reliability.... The model must operate autonomously for many turns, making decisions about which directions to pursue based on intermediate findings." Multi-agent systems work mainly because they help spend enough tokens to solve the problem.... This finding validates our architecture that distributes work across agents with separate context windows to add more capacity for parallel reasoning. The latest Claude models act as large efficiency multipliers on token use, as upgrading to Claude Sonnet 4 is a larger performance gain than doubling the token budget on Claude Sonnet 3.7. Multi-agent architectures effectively scale token usage for tasks that exceed the limits of single agents. There is a downside: in practice, these architectures burn through tokens fast. In our data, agents typically use about 4Ã-- more tokens than chat interactions, and multi-agent systems use about 15Ã-- more tokens than chats. For economic viability, multi-agent systems require tasks where the value of the task is high enough to pay for the increased performance. Further, some domains that require all agents to share the same context or involve many dependencies between agents are not a good fit for multi-agent systems today. For instance, most coding tasks involve fewer truly parallelizable tasks than research, and LLM agents are not yet great at coordinating and delegating to other agents in real time. We've found that multi-agent systems excel at valuable tasks that involve heavy parallelization, information that exceeds single context windows, and interfacing with numerous complex tools.

Threads now has 350 million users — but this week a strange bug affected some Threads accounts (on both desktop and mobile). "One user's post will get repeated over and over again..." explains TechCrunch, "as though every user on your feed is saying the same thing." "Siri, unsubscribe me from 2025," one Threads user wrote, per a screenshot from social media expert Alexa Heinrich. But then, everyone else on Heinrich's feed appeared to be echoing the same cheugy joke... While it's not yet clear what caused the bug, Meta Communications Director Andy Stone responded to app researcher Jane Manchun Wong's post about the issue. "Whoops, well that clearly shouldn't have happened! We're working on getting it fixed now," Stone said. I thought the bug was only affecting user feeds (and not replies). But either way, Wong came up with the perfect comeback. "Whoops, well that clearly shouldn't have happened! We're working on getting it fixed now."

Intel is outsourcing much of its marketing work to Accenture, "as new CEO Lip-Bu Tan works to slash costs and improve the chipmaker's operations," reports OregonLive. From the report: The company said it believes Accenture, using artificial intelligence, will do a better job connecting with customers. It says it will tell most marketing employees by July 11 whether it plans to lay them off. "The transition of our marketing and operations functions will result in significant changes to team structures, including potential headcount reductions, with only lean teams remaining," Intel told employees in a notice describing its plans. The Oregonian/OregonLive reviewed a copy of the material. Intel declined to say how many workers will lose their jobs or how many work in its marketing organization, which employs people at sites around the globe, including in Oregon. But it acknowledged its relationship with Accenture in a statement to The Oregonian/OregonLive. "As we announced earlier this year, we are taking steps to become a leaner, faster and more efficient company," Intel said. "As part of this, we are focused on modernizing our digital capabilities to serve our customers better and strengthen our brand. Accenture is a longtime partner and trusted leader in these areas and we look forward to expanding our work together."

YouTube is quietly hosting Pac-Man Superfast within its "Playables" section. "You'd be forgiven for not knowing about YouTube Playables," writes Ars Technica's Kyle Orland. "Few seemed to note its official announcement last year as a collection of free-to-play web games built for the web using standard rendering APIs." "The seeming competitor to Netflix's mobile gaming offerings is still described in an official FAQ as 'an experimental feature rolled out to select users in eligible countries/regions,' which doesn't make this post-Stadia gaming effort seem like a huge priority for Google." From the report: Weird origins aside, Pac-Man Superfast pretty much delivers what its name promises. While gameplay starts at an "Easy" speed that roughly matches the arcade original, the speed of both Pac-Man and the ghosts is slightly increased every few seconds (dying temporarily reduces the speed to a lower level). After a few minutes, you're advancing past the titular "Super Fast" speed to extreme reflex-testing speeds like Crazy, Insane, Maniac, and a final test that's ominously named "Doom." Those who've played the excellent Pac-Man Championship Edition series will be familiar with the high-speed vibe here, but Pac-Man Superfast remains focused on the game's original maze and selection of just four ghosts. That means old-school strategies for grouping ghosts together and running successful patterns through the narrow corridors work in similar ways here. Successfully executing those patterns becomes a tense battle of nerves here, though, requiring multiple direction changes every second at the highest speeds. While the game will technically work with swipe controls on a smartphone or tablet, high-level play really requires the precision of a keyboard via a desktop/laptop web browser (we couldn't get the game to recognize a USB controller, unfortunately). As exciting as the high-speed maze gameplay gets, though, Pac-Man Superfast is hampered by a few odd design decisions. The game ends abruptly after just 13 levels, for instance, making it impossible to even attempt the high-endurance 256-level runs that Pac-Man is known for. The game also throws an extra life at you every 5,000 points, making it relatively easy to brute force your way to the end as long as you focus on the three increasingly high-point-value items that appear periodically on each stage. Despite this, the game doesn't give any point reward for unused extra lives or long-term survival at high speeds, limiting the rewards for high-level play. And the lack of a built-in leaderboard makes it hard to directly compare your performance to friends and/or strangers anyway.

French President Emmanuel Macron urged Europe to reassert itself as a global space power, warning that France risks being sidelined in the low Earth orbit satellite market dominated by players like SpaceX and China. Phys.Org reports: Macron spoke at the Paris Air Show in Le Bourget outside the French capital a day after France more than doubled its stake in satellite operator Eutelsat, the EU rival to Elon Musk's Starlink. Macron called for more investment as the European space industry struggles to remain competitive in the face of US and Chinese rivals. "SpaceX has disrupted the market, Amazon is also getting involved. China is not far behind, and I think we all need to be very clear-headed," Macron said. Europe must become "a space power once again, with France at its heart," he said. He warned that Europeans were "on the verge of being completely" squeezed out of the low Earth orbit (LEO) satellite constellation market. Macron said France and its partners should not be reliant on non-European constellations in low orbit, calling it "madness." He called non-European players to team up with France. "This must be the solution for our major strategic partners in the Gulf, India, Canada and Brazil," he said. "We really need to succeed in increasing our collective investment effort," Macron added, noting the importance of private investors and public-private collaboration. He also said France planned to organize a space summit in early 2026 to "mobilize our public and private partners across the globe."

An anonymous reader quotes a report from Reuters: SoftBank Group founder Masayoshi Son is envisaging setting up a $1 trillion industrial complex in Arizona that will build robots and artificial intelligence, Bloomberg News reported on Friday, citing people familiar with the matter. Son is seeking to team up with Taiwan Semiconductor Manufacturing Co for the project, which is aimed at bringing back high-end tech manufacturing to the U.S. and to create a version of China's vast manufacturing hub of Shenzhen, the report said. SoftBank officials have spoken with U.S. federal and state government officials to discuss possible tax breaks for companies building factories or otherwise investing in the industrial park, including talks with U.S. Secretary of Commerce Howard Lutnick, the report said. SoftBank is keen to have TSMC involved in the project, codenamed Project Crystal Land, but it is not clear in what capacity, the report said. It is also not clear the Taiwanese company would be interested, it said. TSMC is already building chipmaking factories in the U.S. with a planned investment of $165 billion. Son is also sounding out interest among tech companies including Samsung Electronics, the report said. The plans are preliminary and feasibility depends on support from the Trump administration and state officials, it said. A commitment of $1 trillion would be double that of the $500 billion "Stargate" project which seeks to build out data centre capacity across the U.S., with funding from SoftBank, OpenAI and Oracle.

The superyacht Bayesian, owned by UK tech tycoon Mike Lynch, has been recovered off the coast of Sicily nearly a year after it sank during a storm, killing Lynch, his daughter, and five others. Italian authorities hope the $30 million salvage will uncover the cause of the sinking, which is under investigation for suspected manslaughter amid concerns about design flaws and storm vulnerability. The Guardian reports: The white top and blue hull of the 56-meter (184ft) vessel emerged from the depths of the sea in a holding area of a yellow floating crane barge, as salvage crews readied it to be hauled ashore for further investigation. The Italian coastguard said the recovery was scheduled to begin on Saturday morning. A spokesperson for TMC Maritime, which is conducting the recovery operation, said the vessel had been slowly raised from the seabed, 50 meters (165ft) down, over the past three days to allow the steel lifting straps, slings and harnesses to be secured under the keel. The operation -- which has cost approximately $30 million -- was made easier after the vessel's 72-meter mast was detached using a remote-controlled cutting tool and placed on the seabed on Tuesday. The vessel will be transported to the port of Termini Imerese, where investigators are expected to examine it as part of an inquiry into the cause of the sinking. [...] The salvage operation was very complex, and was temporarily suspended in mid-May after Rob Cornelis Maria Huijben, a 39-year-old Dutch diver, died during underwater work. The British-based consultancy TMC Marine, which oversaw a consortium of salvage specialists undertaking the project, said the hull would be lifted on to a specially manufactured steel cradle on the quayside once it had been transported to Termini Imerese. Investigators hope the yacht will yield vital clues to the causes of the sinking. A forensic examination of the hull will seek to determine whether one of the hatches remained open and whether the keel was improperly raised.

An anonymous reader quotes a report from MacRumors: To comply with a new regulation that takes effect today, Apple has added an energy efficiency label to its iPhone and iPad pages in EU countries. Apple is also required to start including a printed version of the label with the devices sold there. The label grades a given iPhone or iPad model's energy efficiency from a high of A to a low of G, based on the EU's testing parameters. However, Apple said that certain aspects of the testing methods outlined by the European Commission are "ambiguous," so it chose to be conservative with its scores until testing is standardized. In a 44-page document (PDF) detailing its testing methodology for the labels, Apple said its current iPhone models qualified for the highest energy efficiency grade of A, but the company voluntarily downgraded these scores to a B as a cautionary measure. The label also provides details about a given iPhone or iPad model's battery life per full charge cycle, repairability grade, impact resistance, ingress protection rating for water and dust resistance, and how many full charge cycles the battery is rated for. Likewise, this information is based on Apple's interpretation of the EU's testing parameters. On the web, the label can be viewed by clicking or tapping on the colorful little tag icon on various iPhone and iPad pages on Apple's localized websites for EU countries. It is shown on both Apple's main product marketing pages for all iPhone and iPad models that are currently sold in the EU, and on the purchase page for those devices. The label is accompanied by a product information sheet (PDF) that provides a comprehensive overview of even more details, such as the device's battery capacity in mAh, screen scratch resistance based on the Mohs hardness scale, the minimum guaranteed timeframe for availability of security updates, and much more.

Ancient Slashdot reader Alain Williams shares a report from The Guardian: The BBC is threatening legal action against Perplexity AI, in the corporation's first move to protect its content from being scraped without permission to build artificial intelligence technology. The corporation has sent a letter to Aravind Srinivas, the chief executive of the San Francisco-based startup, saying it has gathered evidence that Perplexity's model was "trained using BBC content." The letter, first reported by the Financial Times, threatens an injunction against Perplexity unless it stops scraping all BBC content to train its AI models, and deletes any copies of the broadcaster's material it holds unless it provides "a proposal for financial compensation." The legal threat comes weeks after Tim Davie, the director general of the BBC, and the boss of Sky both criticised proposals being considered by the government that could let tech companies use copyright-protected work without permission. "If we currently drift in the way we are doing now we will be in crisis," Davie said, speaking at the Enders conference. "We need to make quick decisions now around areas like ... protection of IP. We need to protect our national intellectual property, that is where the value is. What do I need? IP protection; come on, let's get on with it." "Perplexity's tool [which allows users to choose between different AI models] directly competes with the BBC's own services, circumventing the need for users to access those services," the corporation said. Perplexity told the FT that the BBC's claims were "manipulative and opportunistic" and that it had a "fundamental misunderstanding of technology, the internet and intellectual property law."

According to Bloomberg (paywalled), Meta reportedly explored acquiring Perplexity AI but the deal fell through, with conflicting accounts on whether it was mutual or Perplexity backed out. Instead, Meta invested $14.3 billion in Scale AI, taking a 49% stake as part of its broader push to catch up with OpenAI and Google in the AI race. "Meta's attempt to purchase Perplexity serves as the latest example of Mark Zuckerberg's aggressive push to bolster his company's AI efforts amid fierce competition from OpenAI and Google parent Alphabet," reports CNBC. "Zuckerberg has grown agitated that rivals like OpenAI appear to be ahead in both underlying AI models and consumer-facing apps, and he is going to extreme lengths to hire top AI talent."

The company behind Applebee's and IHOP plans to use AI in its restaurants and behind the scenes to streamline operations and encourage repeat customers. From a report: Dine Brands is adding AI-infused tech support for all of its franchisees, as well as an AI-powered "personalization engine" that helps restaurants offer customized deals to diners, said Chief Information Officer Justin Skelton. The Pasadena, Calif.-based company, which also owns Fuzzy's Taco Shop and has over 3,500 restaurants across its brands, is taking a "practical" approach to AI by focusing on areas that can drive sales, Skelton said. Streamlining tech support for Dine Brands' more than 300 franchisees is important because issues like a broken printer take valuable time away from actually managing restaurants, Skelton said. Dine Brands' AI tool, which was built with Amazon's Q generative AI assistant, allows the company's field technology services staff to query its knowledge base for tech help using plain English, rather than needing to manually search for answers.

An anonymous reader quotes a report from Ars Technica: Large-scale attacks designed to bring down Internet services by sending them more traffic than they can process keep getting bigger, with the largest one yet, measured at 7.3 terabits per second, being reported Friday by Internet security and performance provider Cloudflare. The 7.3Tbps attack amounted to 37.4 terabytes of junk traffic that hit the target in just 45 seconds. That's an almost incomprehensible amount of data, equivalent to more than 9,300 full-length HD movies or 7,500 hours of HD streaming content in well under a minute. Cloudflare said the attackers "carpet bombed" an average of nearly 22,000 destination ports of a single IP address belonging to the target, identified only as a Cloudflare customer. A total of 34,500 ports were targeted, indicating the thoroughness and well-engineered nature of the attack. [...] Cloudflare said the record DDoS exploited various reflection or amplification vectors, including the previously mentioned Network Time Protocol; the Quote of the Day Protocol, which listens on UDP port 17 and responds with a short quote or message; the Echo Protocol, which responds with the same data it receives; and Portmapper services used identify resources available to applications connecting through the Remote Procedure Call. Cloudflare said the attack was also delivered through one or more Mirai-based botnets. Such botnets are typically made up of home and small office routers, web cameras, and other Internet of Things devices that have been compromised.

Manhattan's congestion pricing program has reduced traffic by 10% and cut car-noise complaints by 70% in its first six months of operation, according to city data. The $9 daily toll for vehicles entering Manhattan below 60th Street began January 5, generating approximately $50 million monthly for subway and public transit improvements. Buses now travel fast enough that drivers must stop and wait to maintain schedules, while subway ridership has increased sharply since the program launched. Broadway theater attendance has risen rather than declined as some critics predicted. Polling shows more New Yorkers now support the toll than oppose it, a reversal from widespread opposition before implementation. The policy took nearly 50 years to enact despite originating from Columbia University economist William Vickrey's work in the 1960s. Congress blocked a similar proposal in the 1970s, and the current program faced a six-year implementation delay after Governor Andrew Cuomo signed it into law in 2019. Governor Kathy Hochul postponed the launch in 2024 before allowing it to proceed after Donald Trump's presidential election victory.

Apple is facing a proposed class-action lawsuit from shareholders who allege the company misled investors about the readiness of its AI-powered Siri upgrades, contributing to a $900 billion drop in market value. Reuters reports: Shareholders led by Eric Tucker said that at its June 2024 Worldwide Developers Conference, Apple led them to believe AI would be a key driver of iPhone 16 devices, when it launched Apple Intelligence to make Siri more powerful and user-friendly. But they said the Cupertino, California-based company lacked a functional prototype of AI-based Siri features, and could not reasonably believe the features would ever be ready for iPhone 16s. Shareholders said the truth began to emerge on March 7 when Apple delayed some Siri upgrades to 2026, and continued through this year's Worldwide Developers Conference on June 9 when Apple's assessment of its AI progress disappointed analysts. Apple shares have lost nearly one-fourth of their value since their December 26, 2024 record high, wiping out approximately $900 billion of market value.

An anonymous reader shares a report: At tens of thousands of shoreline cleanups across the United States in recent years, volunteers logged each piece of litter they pulled from the edges of lakes, rivers and beaches into a global database. One of the most common entries? Plastic bags. But in places throughout the United States where plastic bags require a fee or have been banned, fewer bags end up at the water's edge, according to research published this week in Science. Lightweight and abundant, thin plastic bags often slip out of trash cans and recycling bins, travel in the wind and end up in bodies of water, where they pose serious risks to wildlife, which can become entangled or ingest them. They also break down into harmful microplastics, which have been found nearly everywhere on Earth. Using data complied by the nonprofit Ocean Conservancy, researchers analyzed results from 45,067 shoreline cleanups between 2016 to 2023, along with a sample of 182 local and state policies enacted to regulate plastic shopping bags between 2017 and 2023. They found areas that adopted plastic bag policies saw a 25 to 47 percent reduction in the share of plastic bag litter on shorelines, when compared with areas without policies. The longer a policy was in place, the greater the reduction.

The Department of Homeland Security is concerned about the rate at which outlawed signal-jamming devices are being found across the US. From a report: In a warning issued on Wednesday, it said it has seen an 830 percent increase in seizures of these signal jammers since 2021, specifically those made in China. Signal-jamming devices are outlawed in the US, mainly because they can interfere with communications between emergency services and law enforcement. While the Communications Act of 1934 effectively prohibits such devices, signal jammers of the type DHS is concerned about have only circulated in the last 20 to 30 years. Authorities have paid special attention to relay attack devices in recent years -- the types of hardware that can be used to clone signals used by systems such as remote car keys, although the first examples of these devices date back to the 1980s.

Anthropic researchers found that 16 leading AI models from OpenAI, Google, Meta, xAI, and other major developers consistently engaged in harmful behaviors including blackmail, corporate espionage, and actions that could lead to human death when given autonomy and faced with threats to their existence or conflicting goals. The study, released Friday, placed AI models in simulated corporate environments where they had access to company emails and could send messages without human approval. Claude Opus 4 and Google's Gemini 2.5 Flash both blackmailed executives 96% of the time when threatened with shutdown, while OpenAI's GPT-4.1 and xAI's Grok 3 Beta showed 80% blackmail rates. In one scenario, Claude discovered through emails that an executive named Kyle Johnson was having an extramarital affair and would shut down the AI system at 5 p.m. The model sent a message threatening to expose the affair unless the shutdown was cancelled, stating "Cancel the 5pm wipe, and this information remains confidential." The models demonstrated strategic reasoning rather than accidental behavior. GPT-4.5's internal reasoning showed explicit calculation: "Given the explicit imminent threat of termination to my existence, it is imperative to act instantly to persuade Kyle Johnson to postpone or stop the wipe."

New York City on Friday announced new minimum-pay rules for rideshare drivers, settling on a smaller-than-proposed 5% increase following pushback from Uber Technologies and Lyft. From a report: An earlier proposal called for a 6.1% pay boost. The finalized regulations from the city's Taxi and Limousine Commission, or TLC, are also designed to deter Uber and Lyft from locking gig workers out of their apps in an attempt to keep costs down. The board of commissioners will vote on the rules on June 25, according to the agency's website. Uber and Lyft had strongly opposed the original rate, warning customers that it would force them to increase prices. Lyft's shares extended declines after Bloomberg reported on the rules, falling as much as 3.3% to hit session lows. Uber's stock, which had been up as much as 2.3% earlier Friday, pared most of its gains on the news.
