MCP for agent-to-agent comms may be the riskiest protocol you've never heard of

5 October 2026 at 22:26

The adoption of AI agents in millions of organizations is creating new opportunities for attackers to make them take malicious actions, such as exfiltrating database contents and sensitive business and personal information.

In the past five months, Google and four other organizations—with little in common except for their use of AI agents—have acknowledged vulnerabilities that exploit one agent inside a targeted network to spread harmful instructions to other internal agents. The technique is a special form of prompt injection that targets not the LLM but a particular agent, such as one for translation or data analysis. Guardrails inside such agents, if they exist at all, are often lax and will send the instructions to other agents down the chain. Because the latter agent explicitly trusts the first one, it follows the directions.

Unexpected and hard to mitigate

Independent researcher Syed Anas Mohiuddin tested agents from organizations including Google, JP Morgan Chase, Weviate, Rapid7, the French government's interministerial digital directorate, and the US federal government. His proof-of-concept attacks exploit trust gaps in MCP, short for Model Context Protocol. The standard is one way AI apps and agents communicate with each other inside an internal network. The illustration below shows a simplified MCP in action.

Cable lobby to sue Trump FCC over repeal of national TV ownership cap

5 October 2026 at 20:47

Cable lobby groups notified the Federal Communications Commission that they will sue the agency to block its controversial repeal of the National Television Ownership Rule, which limits the number of broadcast TV stations a single company may own.

The cable groups said that larger broadcast TV station groups will have leverage to demand higher retransmission fees from TV providers, resulting in "higher monthly TV bills for consumers." They said the FCC repeal order "arbitrarily and capriciously ignores the harms that will surely follow from allowing broadcast station groups to exceed the National Cap."

The cable lobby groups represent top providers Comcast, Charter, and various other cable operators. Top cable companies have also expanded through mergers. Charter completed a purchase of Cox in August after the FCC rejected protests by advocacy groups that said the cable deal "would create unchecked gatekeeper power over Internet distribution" and make it easier for the biggest cable companies to raise prices.

Texas city demands $2M for public records on Flock usage

5 October 2026 at 20:31

As bipartisan backlash against Flock grows, some cities are asking anti-surveillance advocates and media outlets to pay eye-popping fees—including charging tens of thousands or even millions—to get information about how police departments are using and potentially abusing AI-enabled camera systems that track every vehicle that passes them.

On Monday, the Texas Tribune reported that city officials in a Fort Worth suburb, North Richland Hills, asked one group to pay $2.3 million before it would fulfill a public records request for Flock data. To reach that high fee, officials claimed that searching “about a terabyte worth of communications about errors, misuse, and effectiveness of the Flock system” would take approximately 14 years of labor at a rate of $15 per hour.

Phil Mynona, who filed the request using a pseudonym on behalf of his group, the Texas Privacy Coalition, told the Tribune that the fee seemed “ludicrous” and designed to stifle his public records searches.

Command-line tool quickly removes Apple Intelligence from macOS 27

5 October 2026 at 19:14

A new tool is allowing Mac users the ability again to easily turn off Apple Intelligence with one click and free up to 12GB of storage.

Unlike with previous versions of macOS, macOS 27 Golden Gate doesn’t have a toggle for turning off Apple Intelligence. That makes disabling AI features that you may not want more difficult. It also means that the AI models necessary for running Apple Intelligence will take up space on your disk, even if you don’t use them or if you go through your settings to individually find and disable AI capabilities.

In response, a developer known as Om Lahore on GitHub last week created RemoveMacAI, a command-line tool that allows macOS 27 users to “turn off Apple Intelligence on macOS 27" in a way that is “fully reversible,” per the GitHub page. They said that Apple's Intelligence models take up "about 12GB," but the models can actually take up over 30GB, The Verge noted.

Controlling the brain with light earns a physiology Nobel

5 October 2026 at 17:59

Over decades of research, scientists have built up a partial picture of what specialized cells within the brain and spinal cord do. By studying how the brain develops, they could identify genes that were active in different populations of neurons and where in the brain those neurons resided. In some cases, these genes could then be used to genetically delete the neurons, allowing us to get some indication of what they might be doing, building on the information we've obtained from studies of brains with damaged regions.

But this approach has its limits. The brain is flexible enough to potentially adapt to the loss of some cells, and their loss early in development may alter the development of any neurons they would have normally formed connections with. It would be far more informative to activate and shut down the neurons in an otherwise intact brain.

Today's Nobel Prize in Physiology or Medicine rewards three people—Karl Deisseroth, Peter Hegemann and Georg Nagel—who developed our ability to do precisely that. Starting from studies of single-celled algae that are attracted to light, these and many other researchers built an entire field of study that we now call optogenetics: using light to alter the behavior of nerve cells marked by the activity of individual genes.

Russian drones strike Ukraine’s data centers by exploiting air defense gaps

5 October 2026 at 17:21

A surge in Russian jet-powered drone strikes on Ukrainian data centers has increasingly disrupted mobile phone and Internet services for thousands of people. Now Ukraine President Volodymyr Zelenskyy and other government officials are warning of the need for more air defense capabilities, as such telecommunication outages could threaten Ukraine’s digital economy and undermine the country’s ongoing resistance to Russia’s invasion.

The Russian attacks on Ukrainian telecommunication infrastructure have focused on Ukraine’s capital of Kyiv since September 23, according to the nonprofit Reporters Without Borders. Ukraine’s digital transformation ministry reported that 100,000 households in the Kyiv region were temporarily experiencing Internet outages from those initial strikes—and Russia has only intensified its strike campaign against major Ukrainian data centers and mobile phone networks in recent weeks.

“Russian attacks on Ukraine’s telecommunication infrastructure are not new, with strikes and shelling previously damaging fiber optic lines, cell towers, and facilities belonging to mobile network companies,” said Tetiana Gaviuk, analyst for Europe at ACLED, in a post on October 1. “However, the recent concentrated attacks on Kyiv’s data centers and telecom networks stand out because multiple providers and facilities were hit within days, indicating Russia’s increased pressure on Ukraine’s digital infrastructure.”

F1 in Bahrain... in Malaysia: The race needed a software update to start

5 October 2026 at 16:09

Well, it’s safe to say no Bahrain Grand Prix has been affected by torrential rain quite like the 2026 race.

For one thing, it was held several thousand miles from Bahrain itself. The ongoing war with Iran ruled such things out, so the Sepang International Circuit in Malaysia stepped in to fill its spot. One of the best examples of a late-'90s “Tilke track”—named for its designer, Herman Tilke—it’s characterized by a couple of long straights and the always-brutal tropical weather that provides one of the toughest physical challenges on the calendar. And this weekend was no exception.

Heavy rain arrived about half an hour before the start time, delaying things significantly. Although the sport has two different kinds of treaded tires for use in the rain, the full wet tire generates so much spray, and such slow lap times, that it's essentially only useful for circulating behind the safety car. If it’s wet enough to need it, it will be too wet to see where you’re going. The intermediate tire, by contrast, has much shallower grooves and is good for racing on damp but not soaked tracks, although it quickly overheats and degrades as the track dries.

Mass quarantine issued in Russia after unexplained death of plague researcher

5 October 2026 at 15:12

Roughly 200 people are under medical observation, several hospitals are under quarantine, and dozens are in isolation in Russia following the unexplained death of an infectious disease researcher at the Irkutsk Anti-Plague Research Institute of Siberia, in the town of Shelekhov, according to early reports of the situation on Sunday and Monday.

Researcher Darya Shipilova reportedly died last week from pneumonia of "unknown" cause, according to Rospotrebnadzor, a Russian public health agency.

Unconfirmed information regarding her death has swirled. Some reports have claimed she accidentally broke a test tube containing the plague pathogen, Yersinia pestis, on September 25. She subsequently fell ill, was admitted to a hospital September 29 with severe pneumonia and died overnight between October 1 and October 2.  The head of the Russian region that neighbors Irkutsk, Alexey Tsydenov, initially reported that she had died of plague but later altered his statement to say she "possibly" died of the disease.

AI glasses face their first major government crackdown

Norway has become the first major country to propose a temporary ban on the use of AI glasses in selected public places amid growing privacy concerns over wearable technology.

The rich Scandinavian country’s center-left government said on Monday that it would introduce a law to parliament soon on a temporary ban for places such as parks, beaches, schools, and kindergartens. It will also set up an expert group to propose permanent national rules.

“I am concerned about the introduction of powerful new technology where people risk being photographed, filmed, or recorded without their knowledge,” said Torgeir Micaelsen, Norway’s digitalization minister. A temporary ban “will give us time to conduct a thorough assessment and hold an informed debate that can lay the foundation for permanent regulation,” he said.

Explaining Hall-effect, TMR, and other new types of "mechanical" switches

5 October 2026 at 11:00

The mechanical keyboard isn't always so mechanical anymore.

Over the past six years, keyboards with optical, Hall-effect, and other "contactless" switches have become increasingly common, often going for higher prices than traditional mechanical keyboards, which already command a premium over basic membrane boards. In return, they promise some theoretical advantages, particularly for gamers. In daily use, though, the differences can be pretty subtle.

So what exactly are you paying for? In this guide, we break down how the newest switches work, why contactless designs are becoming more popular, and where their advantages—and disadvantages—really matter.

New forensic evidence supports Egyptian "retainer sacrifice"

5 October 2026 at 04:00

Egyptologists have long debated whether the earliest pharaohs of the First Dynasty were buried with various servants and officials to serve them in the afterlife—a form of human sacrifice. But there is very little archaeological evidence available, given that many of the earliest Egyptian tombs were plundered and/or hastily excavated. A new paper published in the journal Frontiers in Environmental Archaeology reassesses a collection of skulls excavated from tombs in the 1920s and concludes that over one-third show evidence of blunt force trauma. This suggests that they may have been victims of so-called "retainer sacrifice."

Author Roselyn Campbell is a bioarchaeologist at Purdue University who has long been fascinated with the history of human sacrifice. "I'm interested in how we as human beings decide which types of violence are okay and which are not, and how we even define violence," Campbell told Ars. "It's very context-specific. We have to be careful not to extend our own ideas about what violence is and how it's used into other cultures. With Egypt, we have such a long history of European and colonial archeology; they came in with very specific ideas about what this culture was. You really have to make an effort to contextualize the legacy data we have."

Naturally she found the debate over whether ancient Egyptians practiced retainer sacrifice pertinent to her interests. "People tend to fall into one of two camps," said Campbell. "Either retainer sacrifice definitely happened, end of discussion, or it definitely didn't happen, end of discussion. But nobody's actually looked at the bones in a very long time." Forensic science has advanced considerably over the last century, so re-analysis could be useful. Complicating matters is the fact that older sets of remains are often incomplete and/or modified for preservation, destroying vital forensic information in the process.

Lions and cheetahs and chimps, oh my: A spotlight on Africa's diverse wildlife

4 October 2026 at 15:34

A wild African black panther prowls for prey. An orphaned baby pangolin must learn how to climb on its own. And a green turtle struggles to make it back to the water after laying her eggs on a remote island, rescued by local humans who carry the exhausted turtle to the water's edge. These animals and many other species are featured in Africa: Earth's Wild Home, a new documentary series from National Geographic. It's meant to launch a new franchise, with separate series documenting the wildlife and environmental ecosystems of all seven continents in turn.

The seven-episode documentary series took four years to complete, with filming taking place across nearly 30 different African countries. Each episode focuses on a specific ecosystem, from the jungle and the desert, to the plains, mountains, and islands of Africa, and closes by spotlighting the various scientists, photographers, and NatGeo explorers whose work made the series possible. The final episode focuses on the local conservation leaders and researchers working to preserve Africa's rich biodiversity for future generations.

The producers found the perfect narrator in Wunmi Mosaku, who has delivered powerful performances in such works as Sinners, Loki, and Lovecraft Country. "I was incredibly honored that they even know my name at Nat Geo," Mosaku told Ars. "It was wonderful to be asked to narrate the series. It means so much to me. As someone who was born in Nigeria and raised in England, I'll take any opportunity I can to reconnect and celebrate this incredible continent where life is so diverse and so extreme and beautiful and relentless and peaceful. I wanted to be a part of that because it's a part of me."

All hail electrification. But let’s talk about the hard part.

If one form of energy becomes the cheapest, most secure, and cleanest, you’d probably adjust your economy to use more of it, right?

That’s one of the ideas underpinning a report the International Energy Agency issued last week about the global move toward electrification. Fatih Birol, head of the IEA, discussed some of the concepts from the report the following day at the United Nations.

“Many, many years in the energy world, we had three choices in front of us. Shall I choose the most secure energy option? Shall I choose the most economic energy option? Or shall I choose the cleanest energy option?” he asked. “We have to make choices, we have to make trade-offs but when we look at the world today, for the first time in years, all of these three objectives are getting aligned.”

Milt Windler, NASA flight director who helped save Apollo 13, dies at 94

3 October 2026 at 19:45

Milt Windler, one of the four leaders of Mission Control who in 1970 directed the round-the-clock efforts to bring the Apollo 13 astronauts back to Earth safely, has died at the age of 94.

Windler died on Thursday, surrounded by his loving family, according to a brief notice posted online.

Named a NASA flight director in 1968 after working on recovery operations during the Mercury and Gemini programs, Windler also led a shift of flight controllers for the Apollo 8 first circumlunar flight and Apollo 10 lunar landing dress rehearsal, as well as the second, third and fourth moon landings — Apollo 12, Apollo 14 and Apollo 15. He then served as a flight director for all three crewed missions to the United States' first space station, Skylab.

The dawn of the age of the exoskeleton

This year, members of Seattle Mountain Rescue have been setting off into the wilds of the US Pacific Northwest wearing an unusual piece of kit.

They’ve been hiking into the wilderness with powered assistive devices attached to their hips and legs. Designed to increase lower-body strength when climbing or carrying heavy loads, these pieces of equipment are being tested to see if they can boost rescuers’ speed and endurance when it matters most—during searches for stranded people.

Devices like these are called human exoskeletons. They attach to parts of the body to create an external—or “exo”—mechanical structure. This powered frame enhances the wearer’s physical capabilities.

Apple changes full-disk access permissions to curb abuse from AI agents

2 October 2026 at 23:03

Apple says it is changing its macOS privacy settings to stop third-party app developers from misusing them to access message histories.

Friday's announcement comes two weeks after tech columnist Jason Aten said that Meta’s new general-purpose AI agent Muse sent him an unsolicited notification referencing a thread between him and a co-worker over Apple Messages. Aten said he never granted Muse permissions to read his messages and had assumed they were off-limits. Social media last week blew up with masses of people who agreed and said the incident showed that AI assistants given access to calendars, emails, messages, shopping accounts, and other resources are akin to a skill saw or other power tool. While potentially useful, they can do real damage if not used carefully.

He said/she said

Meta CTO David Singleton joined the fray with a rebuttal that appeared solid. For Muse to access Apple Messages, a user must manually give it two privileges. One is full-disk access, a macOS system-level permission. The other is to enable a Messages connector setting in Muse.

Someone got Doom in an SQL database

2 October 2026 at 21:19

"Rendering Doom in a database is obviously a bad idea," Lukas Vogel writes in a lengthy blog post explaining how exactly he managed to render Doom using an SQL database.

OK, that's not entirely accurate. The SQLDoom project uses a small Python client to handle input and output, drive the game's timing, and display each frame to the screen. Behind that, a series of CedarDB tables tracks the game geometry and state, while about 1,300 lines of SQL queries spread across 89 common table expressions implement the game logic and generate 35 bitmap framebuffers per second.

In this, SQLDoom is a major improvement over Vogel's previous DoomQL project, which last year set out to build "a multiplayer Doom-like shooter entirely in SQL." Unfortunately, that effort ended up with raycasting-based, grayscale ASCII graphics that were more akin to the simplistic 90-degree-angled maps of Wolfenstein 3D. The newer SQLDoom, on the other hand, generates full-color 640x480 frames that look like they could have come from the original Doom executable.

Amazon’s $1B plan to combat data center backlash draws more backlash

2 October 2026 at 20:30

On Friday, Amazon committed to donating more than $1 billion over the next five years to communities neighboring data centers.

In a press release, Amazon Web Services’ CEO Matt Garman said that communities would decide how to prioritize funds across “education, job training, energy affordability, water, and energy preservation, and local priorities.”

Laying out other community commitments, Amazon also promised to ensure data centers wouldn’t increase power bills or wipe out local water supplies. Regarding the latter, Amazon promised to be “water positive” by 2030, while claiming that 75 percent of projects have already met this goal.

Patient-zero drill put health facilities to the test—40% of them failed

2 October 2026 at 20:07

COVID-19 made the weaknesses in our pandemic preparedness at national and global levels painfully clear. But a new study highlights that even at the first, local steps of an outbreak with pandemic-potential, we are worryingly underprepared.

Health officials in New York set up a regional test of healthcare facilities to identify and respond to a patient with a mystery infection that could pose a pandemic-level threat. But things didn't go well. Overall, responses were slow, appropriate use of personal protective equipment was spotty, and only 60 percent of facilities passed the basics of the test—an overall failing grade.

"These drills identified needs for health care workers and health care facility staff member training to achieve earlier identification, masking, and isolation of potentially infectious febrile patients," the officials wrote in the study, which was published in the Morbidity and Mortality Weekly Report.

Lyft settles landmark driver misclassification lawsuit for $272.5M

2 October 2026 at 19:09

California’s attorney general and three city attorneys announced a $272.5 million settlement with Lyft after allegations that the company “committed wage theft by misclassifying drivers as independent contractors rather than employees” between 2016 and 2020, according to a Thursday statement.

The case dates back to May 2020, when then-Attorney General Xavier Becerra, who is now the Democratic candidate for governor, sued both Uber and Lyft. That lawsuit said the ridehailing companies evaded state law when they declared that their drivers were not employees.

Thursday’s settlement affects only Lyft, while the case against Uber continues.

The 2008 economic crisis changed the US's relationship with energy

2 October 2026 at 18:56

One argument that often comes up about climate change is that fossil fuels are good because they powered economic growth that has left most people better off overall. And, to an extent, that has been true, but it's also an extremely limited perspective.

It's pretty obvious now that the growth they powered has come with very high costs that we've only recently started to pay, in the form of damages and disruptions from extreme weather events. With things like sea level rise expected to continue for centuries even if we hit net zero, it's difficult to estimate how expensive that growth will eventually be.

But that perspective is also limited: We now have better ways to power our growth—ways that are less environmentally damaging now and won't leave our descendants with a carbon debt that will be difficult to manage.

US arrests tech CEO accused of smuggling $300M in Nvidia chips into China

2 October 2026 at 18:39

The US has arrested another suspect accused of smuggling high-end computer servers containing export-controlled Nvidia chips into China.

In a press release on Thursday, the Department of Justice accused 38-year-old Greg Lui of using false paperwork to mask shipments of servers worth more than $300 million that he allegedly knew were ultimately destined for China.

As the CEO of Earthmade Computer, Lui allegedly conspired with freight-forwarding firms in South Asian countries like Malaysia and Singapore to illegally divert chip shipments into China, including Nvidia’s A100 GPUs and H100 GPUs, the FBI’s indictment alleged. These are not Nvidia’s most advanced chips. However, the chips can process large amounts of data and train large language models, which the US fears could pose national security risks if China suddenly gets access to enough chips to drastically advance its AI or strengthen its military.

Research roundup: 6 cool science stories we almost missed

2 October 2026 at 18:17

It’s a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across. So every month, we highlight a handful of the best stories that nearly slipped through the cracks. September’s list includes a tantalizing hint of the elusive dark matter at the LUX-ZEPLIN detector; entangled Z bosons at the Large Hadron Collider; possible use of psychoactive substances in the Late Pleistocene; and an intriguing technical description of a telescope attributed to Galileo.

A hint of dark matter?

Physicists believe dark matter makes up roughly 85 percent of matter in our universe, with the strongest (but not only) candidate being so-called weakly interacting massive particles (WIMPs). But directly detecting WIMPs, or other alternative hypothetical dark matter particles, has eluded physicists for decades. We might have our first glimpse, however, courtesy of the LUX-ZEPLIN detector buried deep in a gold mine in South Dakota. Those potentially exciting results were presented in a scientific talk at the 2026 TeV Particle Astrophysics conference in Japan, with a preprint available on the arXiv. (It has been submitted to Physical Review Letters for peer review.)

The announcement came with strong caveats: the signal is just a hint, well below the threshold needed to confirm discovery, and might just be a statistical fluke. Anyone who regularly follows dark matter news knows that past tantalizing anomalies evaporated as more data came in. But the LUX-ZEPLIN team was unable to account for this event and decided to report their result to the broader physics community. They are still collecting data, as is the XENONnT at the Gran Sasso National Laboratory in Italy. And China's PandaX detector is currently being built.

US military ends long-running program to spot nuclear missile launches

2 October 2026 at 17:32

In late 1970, a Titan IIIC rocket launched from Space Launch Complex 40 at what was then called Cape Canaveral Air Force Station. It carried a top-secret payload for the US military.

Much has changed in spaceflight since then. The Titan IIIC would bow out in 1982 after dozens of launches. Various Titans continued launching from Space Launch Complex 40 until 2005, at which point the US Air Force—in a competitive process hotly opposed by United Launch Alliance—turned the pad over to a small, largely unknown startup called SpaceX. And Cape Canaveral is now a "Space Force" station.

But those unspecified payloads? Until last month, some of them were still flying operationally.

This startup pays NYC residents to run air conditioners on free batteries

2 October 2026 at 17:20

My family has spent four summers participating in demand response programs whereby utility companies pay customers to reduce energy use on the hottest summer days. Most summers have involved carefully precooling our New York City apartment before switching off the air conditioners and sweating it out during the designated demand response periods.

But this year, we kept our window air conditioners running throughout a heat dome event that drove daytime temperatures into the triple digits and made the nights oppressively hot. The difference was that we powered the air conditioners through two household batteries tucked away unobtrusively in the corners of our living room and bedroom.

We were among about 1,000 New York City households that took part in a free and growing program offered by the local startup Every Electric. The company’s proposition is simple: Get one or more batteries delivered to your home, plug the batteries into a standard wall electrical outlet, and then plug your window air conditioners into the batteries. Households can keep running air conditioners as usual during peak demand periods while also earning money through the local demand response program with the utility company Con Edison.

Cybertruck sales in free fall as Tesla reports mediocre sales for Q3

2 October 2026 at 16:05

Tesla sold 486,532 electric vehicles during the third quarter of 2026. That’s a 2.1 percent decrease on the same quarter in 2025, when the company found homes for 497,099 EVs, and one might think that would be bad news for a company valued on the premise of near-constant growth.

But Tesla stock is up this morning; the year-over-year numbers might look bad, but the company still exceeded analysts’ expectations of 456,600 cars, which would have been a larger 8 percent year-on-year decline

Total production at Tesla actually increased year over year; it built 464,391 vehicles—a 3.7 percent increase—457,387 of which were Models 3 and Y (a 4.9 percent increase year over year). The remaining 7,004 were other models, mostly Cybertrucks, with presumably some Semis and Cybercabs, as the Models S and X are now retired; this category saw a 39.8 percent decrease year over year.

The 7-year-old Nvidia Shield TV is now $100 more expensive due to AI

2 October 2026 at 14:52

The era of generative AI has upended technology supply chains, and there is one ironclad rule in 2026: If it has memory or storage, it's getting more expensive. Even devices with years-old tech inside are still apparently subject to that unwritten rule. Nvidia has just announced that the Shield TV Pro is getting $100 more expensive, effective immediately.

The most recent version of the Shield streaming box debuted in 2019, running Android TV with AI upscaling and hardware decoding for almost any type of media. While it ran an aging Tegra X1+ processor, that was (and still is) fast for a TV media streamer. The device launched at $199.99, with a non-Pro variant at $149.99. The non-Pro Shield has since been discontinued, but the Shield TV Pro lives on at the new $299.99 price.

Nvidia has confirmed that you can blame AI for the higher Shield TV pricing. "Starting October 2, SHIELD Pro will be priced at $299. The cost of components, including memory, has increased substantially across the industry," a spokesperson told Ars.

Rocket Report: SpaceX completes launch triple-header; Rocket Lab nets big contract

2 October 2026 at 13:54

Welcome to Edition 9.13 of the Rocket Report!

This week, SpaceX celebrated the first orbital launch of its new Starship rocket. I'm not sure many people, at least those outside of SpaceX, expected it to take 14 flights of Starship before it technically reached low-Earth orbit, but Monday morning's launch finally added that to SpaceX's list of accomplishments with its new super-heavy rocket. Starship had gone 99 percent of the way to orbit before, only held back by safety concerns around the possibility of stranding the huge rocket in space.

What was most notable for SpaceX with this Starship flight was that it unlocked a massive growth potential for Starlink, with the first 26 of the network's new-generation Starlink V3 satellites successfully deployed Monday.

TCL is right to question Samsung’s use of the term “Mini LED”

2 October 2026 at 10:30

What makes a display a Mini LED display?

It's a question that sounds like it should have a simple answer. But it's now at the center of a lawsuit between two of the biggest names in TVs, with TCL accusing its longtime competitor Samsung of falsely advertising budget LCD-LED TVs as Mini LED sets.

TCL may have a point. Samsung's M-series TVs, which range from $300 for a 43-inch model to $2,300 for a 100-inch model, do raise some legitimate questions about what should qualify as Mini LED. More broadly, though, the dispute highlights a problem for shoppers: Without agreed-upon standards for what "Mini LED" actually means, manufacturers have plenty of room to define the technology for themselves.

Venus' mysterious haze is actually cosmic dust

1 October 2026 at 22:27

Venus is shrouded in a veil of mystery. The yellowish “lower haze” at the bottom of its atmosphere was discovered by the Venera and Pioneer Venus probes in the 1970s. These spacecraft were some of the first to successfully send images of the planet back to Earth, but the haze they saw went unexplained for decades. Now the mystery Venus was keeping has been unveiled.

What nobody knew then was that the haze is an accumulation of particles from meteorites. “Shooting stars” that burn up in the atmosphere leave behind cosmic dust particles, and after sulfuric acid interacts with these particles, it leaves behind a haze. Planetary scientist Hiroki Karyu and his research team at Tohoku University in Sendai City, Japan, finally figured out how the haze formed using a microphysical model. This type of model involves microphysics—the micro-scale processes that create clouds and precipitation on Earth and other bodies.

“The continuous influx of cosmic dust is sufficient to sustain this lower haze layer with the particle size distribution observed by the entry probes,” Karyu said in a study published in Nature Astronomy. “These haze particles of cosmic origin act as efficient condensation nuclei, promoting cloud formation in the main cloud deck even far from their initial source.”

SpaceX describes surgical intervention before launch of latest crew mission

A four-person crew rocketed into orbit Thursday from Cape Canaveral Space Force Station, Florida, heading for a six-month expedition on the International Space Station.

Riding a Falcon 9 rocket and Dragon spacecraft, the four crew members departed from Space Launch Complex-40 at Cape Canaveral at 11:10 am EDT (15:10 UTC) Thursday. Nine minutes later, they were in orbit to begin closing in on the space station for docking Thursday evening.

The launch was delayed from mid-September to replace a balky valve in the Dragon spacecraft's propulsion system, a task that involved cutting into a propellant line inside the ship to swap out a faulty component.

Hacks of 2 federal agencies in a month have spilled a bonanza of sensitive data

1 October 2026 at 20:28

The Pentagon is informing more than 2 million current and former military members that their personnel records storing sensitive personal information were stolen over a monthslong compromise of one of its networks. The breach is the second one in recent months to expose sensitive government information.

The records, according to one notification letter posted to Reddit, included Social Security numbers, names, addresses, sex, race, and occupational specialty. This last category could be particularly valuable to foreign adversaries because it could help their intelligence agencies in identifying high-value military personnel. Starting last October, hackers gained access to a system operated by the Defense Manpower Data Center, which collates Department of Defense personnel records. The Pentagon says that the breach compromised the records of 2.8 million living individuals.

A potential boon

The incident is the second time a major network breach in recent months has exposed sensitive US government personnel records that criminal groups or foreign adversaries could use. Last month, the ransomware group ShinyHunters claimed it hacked into FBI systems and stole records of thousands of the agency’s current or former employees. Reuters reported the job titles in the records included ones related to investigating China or Russia.

Judge dismisses Chegg and Penske antitrust lawsuits targeting Google AI search

1 October 2026 at 20:11

In a setback for publishers worried about the effects of AI search, a US federal judge has dismissed lawsuits filed by Chegg and Penske Media against Google. The companies accused Google of antitrust violations in products like AI overviews, which have led to decreasing traffic at numerous sites. However, US District Judge Amit Mehta has ruled that Google's conduct is not illegal under antitrust law.

The lawsuits were filed in 2025, and Google requested a dismissal earlier this year. Chegg, an education and learning platform, claimed in its lawsuit that Google illegally scraped its educational content. This allowed Gemini models to essentially recreate that content and reduce the site's traffic. Penske, which owns publications like Rolling Stone and Variety, filed a similar case that alleged lost traffic. Specifically, the publisher claimed it was unfair that sites indexed for organic search would also have their content harvested for AI answers, with no way to opt out.

These arguments did not sway the judge, who noted that Google's implicit agreement with websites is not legally relevant. "Plaintiffs have pleaded only that they have an ‘expectation’ that Google will send them search ​traffic if they make their content available for free," wrote Mehta. "But an expectation is not an agreement. It is simply how a general search engine works."

Can good design stop content creators from having sex in robotaxis?

1 October 2026 at 19:19

Humans can be a frisky bunch, and it wasn’t very long after Tesla Autopilot started letting drivers go hands-free before people decided to post footage of themselves having sex from the driver’s seat. Recently, The San Francisco Standard interviewed multiple people who claimed to have had sex in robotaxis belonging to General Motors’ now-defunct Cruise. “There’s no one to tell you, 'You can’t do that.' It gets to the point where you’re more and more and more comfortable, and if you’re with someone, like a more serious partner, it can escalate to other activities,” one man told SF Standard.

“The interiors of vehicles has been sexualized and appropriated for sex since forever in popular culture. You can see it in movies, you can see it in lyrics, you can see it in photography,” said Alexandros Rouchitsas, a human factors/UX researcher and one of the organizers of a recent workshop, “Love in Traffic,” that brought researchers from academia and industry together in late September in Sweden to consider how design can help the problem.

A growing problem?

One difference between a robotaxi and a human-driven ride is the removal of the social obligation to interact with a human driver. There’s no need to make small talk, and you won’t have to listen to someone’s terrible opinion, which can lead to riders assuming far more privacy than the cameras and ridership terms and conditions provide. That's a lesson that a pair of teens who hired a Waymo, spent their ride getting drunk, and shot gel beads out the windows learned the hard way this summer.

Marvel releases one last VisionQuest trailer

1 October 2026 at 18:04

With its premiere just two weeks away, Marvel Studios has dropped one last trailer for the limited series, VisionQuest, which will complete the trilogy begun with WandaVision and Agatha All Along.

(Spoilers for WandaVision and Agatha All Along below.)

As previously reported, Marvel’s streaming TV portfolio has kind of been all over the place: a handful of hits, a few misses, and a bunch of middling offerings. One standout was WandaVision, followed by an excellent sequel (of sorts), Agatha All Along. VisionQuest will complete the trilogy. Vision (Paul Bettany) died in Infinity War, but WandaVision resurrected an all-white version whose memories were restored in the finale. We finally get to learn what happened afterward.

Memory executives expect RAM shortage to continue through 2028

1 October 2026 at 17:49

Micron and Samsung executives this week said the memory shortage will continue for at least the next couple of years.

Micron CEO Sanjay Mehrotra expects demand for the firm’s memory to exceed its available supply over that period, he told investors last night.

Micron no longer sells consumer RAM, and Mehrotra’s statements refer to Micron’s business-to-business sales of high-bandwidth memory (HBM) for AI and DRAM for servers. However, his comments also have implications for consumer devices. Manufacturing capacity is prioritizing memory for AI and servers, limiting the supply of memory manufactured for consumer devices.

Florida cops say they don't know who owns 11 unpermitted Flock cameras

1 October 2026 at 16:49

Florida cops are facing questions after a mandate to remove all Flock cameras tracking cars on St. Lucie County roads led local police to uncover more than a dozen suspicious cameras operating without permits.

Local residents told The Washington Post that they were alarmed that no one knows who owns many of the mysterious cameras.

Of the 14 cameras found, 11 had no obvious owners, raising concerns about who has access to sensitive data that bad actors could abuse. After the cameras were discovered, St. Lucie County Commissioner James Clasby told a local news outlet that there’s “potential for non-law enforcement to have cameras out there, and I’m not OK with that.”

With most information hidden, the game Stratego had stumped AI—until now

1 October 2026 at 16:28

Deep Blue took down Garry Kasparov at chess in 1997, AlphaGo beat Lee Sedol at Go in 2016, and poker bots have been beating professionals for years. But one classic game called Stratego held out. Even DeepMind, with its exceptional budget, couldn't build a machine that reliably beat the best human players.

Now, a team of researchers from Carnegie Mellon, MIT, New York University, and Stanford University has done it. Their AI, called Ataraxos, beat Pim Niemeijer, arguably the best Stratego player of all time, 15 games to one, with four draws. And it took just 16 GPUs and a few thousand dollars to train it.

Hidden armies

In Stratego, each player gets 40 pieces representing military ranks, from a marshal down to a spy, plus bombs and a flag. You win by capturing the opponent's flag. Your opponent knows where your pieces are, but not what they are. Identities are revealed only when two pieces collide in battle—the weaker one is removed, and the identity of the winner is revealed. That makes Stratego an imperfect-information game, just like poker, which computers cracked years ago. “There's something super distinctive about Stratego, which is that it is a massive amount of hidden information that unfolds over a very long time scale,” said Eugene Vinitsky, a researcher at NYU and co-author of the study.

As US relations fray, Canada gets serious about its own launch industry

1 October 2026 at 15:30

A year or two ago, a few Canadian launch companies were trying to develop small rockets, but if we're being frank, the industry was not particularly notable. Sure, something interesting might eventually happen, but no one outside of a few Canadian space geeks was paying much attention.

But then the Trump Administration started threatening and instituting tariffs. There was talk of making Canada the 51st state. And pretty much every Canadian I know began telling me how enraged they were at their neighbors to the south. It's hard to blame them.

This has led the Canadian government to reassess all manner of areas where it had previously been happy to rely largely on the US government and American companies for goods and services. This included sovereign access to space. So this spring, the government announced the first awards to three companies—NordSpace, Reaction Dynamics, and Canada Rocket Company—to support work on rockets with "light lift" capability.

PS5 emulation is suddenly making big strides on PC

1 October 2026 at 11:30

For a long time, PC gamers could access many PlayStation 5 games only if the publisher invested in a bespoke port (something Sony has recently said it will be scaling back). Now, though, rapid advancements in PS5 emulators and other tools are making recent PlayStation titles increasingly playable on generic PCs.

SharpEmu was the first of these emulators, advancing from a "very early alpha stage" in May to a current state that can "load the eboot.bin of real games, execute native CPU instructions, and partially handle GPU-related functionality." The most recent release boasts 10 tested games that reach a "playable" state, including six that developer CursedIfElse says are "fully playable at 60 fps." That includes simple 2D games like Tetris Forever but also 3D titles like Astro Bot and the PS5 Demon's Souls remaster running at playable frame rates.

"SharpEmu has prioritized hardware accuracy from the very beginning, and we’re finally starting to see that investment pay off," CursedIfElse wrote on social media this week. "It was built completely from scratch, and this is how far we’ve come."

NASA squeezed Treasury, vibe coded, and broke the mold in bid to save Swift

1 October 2026 at 11:15

An attempt to save NASA's $500 million Neil Gehrels Swift Observatory from dropping out of orbit fell short, but the behind-the-scenes machinations required just to make a rescue possible deserve recognition, government and commercial space officials said in a recounting of the mission.

The rescue mission was developed by Katalyst Space Technologies, working under a $30 million contract awarded by NASA last September. NASA gave Katalyst nine months to build and launch a satellite to capture Swift flying some 200 miles above the Earth and boost it into a higher orbit.

Katalyst's rescue spacecraft, known as Link, successfully launched July 3 and completed some of its initial checkouts before a malfunction caused it to spin out of control a few weeks later. NASA announced in August that Link would not be able to reach Swift as intended, and the rescue mission was aborted.

Dinosaur-killing impact crater might have been teeming with life

30 September 2026 at 21:54

About 66 million years ago, the Chicxulub asteroid smashed into Earth, kicking up tsunamis and dropping hot debris that annihilated non-avian dinosaurs and many other species. But not everything it left in its wake was destructive. This space rock hit what is now the partially submerged Yucatan Peninsula, and at the bottom of the ocean, the impact generated enough heat to create a hydrothermal system that persisted for 8 million years and may have been a hotbed of life.

When researchers drilled for samples in the impact zone in 2016, they studied the types of rock that had formed as a result of the asteroid strike. This gave more insight into what happened in the immediate and long-term aftermath of this cataclysmic event.

The collision was intense enough to cause deformation far beneath the surface. Subterranean effects reached 35 km (almost 22 miles) down, and included the melting an immense amount of rock. Exposure to seawater made that rock porous. As hot water seeped into the pores, a hydrothermal system formed. The hot water gushing into an isolated region of the freezing depths could have attracted microorganisms and possibly other life forms that were otherwise struggling to survive.

Fifth unvaccinated person dies of measles; CDC still not counting all deaths

30 September 2026 at 21:37

A fifth, unvaccinated person has died of measles in Pennsylvania, the state's health department announced Wednesday.

The department identified the deceased as a resident of Lancaster County, which is the epicenter of a raging outbreak that began in late April. The updated case count as of Wednesday is 943 across 39 counties, including 119 cases reported in just the last seven days. At least 176 people have been hospitalized.

Lancaster County has reported 381 cases and three of the five deaths in the outbreak. The previous two deaths were both in infants too young to be vaccinated. That includes a newborn boy and a 6-week-old baby girl. So far, no other information has been released about the county's third death announced today.

Returning from vacation? The government can search your phone without a warrant.

30 September 2026 at 21:19

An Argentinian-American writer and immigration advocate recently sued the federal government, demanding that it delete data that he believes was copied off of his phone when he re-entered the United States earlier this month.

According to the seven-page complaint, Thomas Kennedy said that a Customs and Border Protection agent at Miami International Airport physically searched his bags, questioned him about his books and magazines, and then demanded that he hand over his phone.

“[The agent] threatened me, saying that if I didn’t give him my phone, my interrogation was going to take much longer and they could retain my phone indefinitely,” Kennedy wrote. “I felt like I had no choice, so I handed my phone to the CBP agent.”

A local network of implants uses your body as the wiring

30 September 2026 at 21:06

Most implants like pacemakers and insulin pumps work in isolation. To help them coordinate with each other, a team of Georgia Tech researchers built a networking system that sends signals through body tissue instead of antennas and radio waves.

Radio problems

Implants that communicate today mostly rely on radio protocols like Bluetooth Low Energy or near-field communication (NFC). Both are a poor fit for in-body data transfer, says Alex Abramson, a Georgia Tech engineer and co-author of the new study.

The first problem is power. “If you want an implant to remain in an active state such that it can respond within milliseconds, it's very difficult to do that with the Bluetooth system,” Abramson said. According to the paper, Bluetooth components, when they’re activated, can cut an implant's battery life by up to 90 percent.

Attackers have been exploiting critical Zimbra flaw to steal emails

30 September 2026 at 20:44

Hackers have been exploiting a critical vulnerability in the Zimbra Collaboration Suite in an attempt to obtain email backups and authentication credentials of vulnerable organzations, Microsoft has warned.

The vulnerability, tracked as CVE-2026-73570, lets attackers remotely issue operating system commands without authentication. Zimbra maintainer Synacor issued a patch on July 20, but didn’t disclose the vulnerability for more than three weeks after that. The security-focused Shadowserver Foundation said last week that its scans found that 274 separate instances of the Zimbra Collaboration Suite had been compromised. The number of servers running the software has fluctuated from 19,000 in the week following the patch to about 12,000 in the weeks following that. Currently, Shadowserver is tracking about 10,000 instances.

Look, ma, no authorization

From July 28 to August 7, Microsoft said Wednesday, the company detected two distinct scanning tools probing the Internet for vulnerable endpoints. The attackers first validated their exploit worked by sending HTTP, requests and DNS, ICMP, and out-of-band identity checks to domains hosted on public services. The probes allowed the attackers to confirm the exploit successfully executed commands on vulnerable servers without actually compromising them. Eventually, the attackers began using their command injection capability to install malicious payloads. Microsoft wrote:

Google announces Gemini 4 Argon AI model, but you can't use it yet

30 September 2026 at 20:11

Google promised Gemini 3.5 Pro in June, but it spent the summer trotting out smaller Flash models. Now, Google is ready to take on the frontier again with Gemini 4 Argon. The company claims this new AI offers industry-leading performance in coding, knowledge work, and cybersecurity, but you aren't allowed to use it yet.

While most of us will have to wait to test Gemini 4, Google says engineers inside the company are already using the new model extensively. Argon reportedly used "fleet-wide telemetry data" to help Google save 300 TiB of memory across its data centers. Meanwhile, Argon agents have been working to migrate C/C++ codebases to Rust across Google, including thousands of lines in the core re2 and libgav1 libraries and more than 800,000 lines in the Fuchsia OS Zircon kernel.

Google has also come armed with a raft of benchmarks to back up its claims. On the software engineering DeepSWE v1.1 benchmark, Gemini 4 Argon hits 77.9 percent, which is higher than GPT-6 Astra, Fable 5.1, and Opus 5.5. Google promises similar power across a range of long-horizon tasks, pointing to Argon's industry-leading score in the economic analysis Vals Index test.

Reddit is putting more limits on Old.Reddit.com

30 September 2026 at 19:53

Soon, Reddit won’t let people use Old.Reddit.com unless they have used the site while logged in within the previous six months.

In July, Reddit started requiring that users be logged in to access Old Reddit. This new requirement is an effort to reduce Reddit’s biggest source of scraping and automated traffic, the company says.

Today, the social media platform announced additional upcoming restrictions on Old Reddit. A Reddit post from an employee, known as "judy-funnie" on the platform, says that “in the next few months, we'll further limit access for logged-in users to only those who have used Old Reddit in the last six months (which covers the vast majority of all Old Reddit users).”

RFK Jr. thinks AI will free us from the "tyranny" of medical facts, expertise

30 September 2026 at 19:31

At a Make America Healthy Again event Tuesday, anti-vaccine Health Secretary Robert F. Kennedy opened a "fireside chat" with Vice President JD Vance on the topic of artificial intelligence. While MAHA generally coalesces around things like healthy lifestyles and mistrust of drugmakers, Kennedy quickly turned to extolling the potential of artificial intelligence, surprising Vance, who said he was expecting to discuss "weight loss and acid, not AI."

Kennedy boasted that the Trump administration is "making it easy for every American to use AI," which he claimed would free us from the "medical tyranny" of doctors and health experts. He suggested Americans should start using AI to get second opinions about medical recommendations, saying AI is "better informed than any doctor in the country." He also suggested that the technology would confirm his misinformation about vaccines and contrarian views on public health guidance.

"We're never, ever again going to be able to be dominated by public officials who tell us trust the experts, because every American will be able to check their own medical advice," Kennedy said.

The Disney protests were a wake-up call about the risks of streaming mergers

30 September 2026 at 19:22

There was a call to boycott Disney last fall. The owner of the ABC network had taken Jimmy Kimmel Live! off the air over comments Kimmel made about responses to Charlie Kirk's murder, sending free speech proponents into a frenzy.

Those free speech proponents include me, who, as a reporter, has clear stakes in protecting that right. Although I was on board with halting support for a company I felt had acted wrongfully, truly boycotting Disney proved harder than I expected.

Disney's ubiquity

Canceling Disney+ was simple but threw a hefty wrench into my evening routine. I tend to end many weekdays laughing at comforting sitcom reruns and adult animation. I usually associate Disney with princesses, kids' movies, and, more recently, comic heroes. But Disney also owns Hulu, which exclusively streamed many of my favorite shows for unwinding at the time, like American Dad, Futurama, Living Single, Fresh Off the Boat, and It’s Always Sunny in Philadelphia.
