The objective of some of the OpenAI agents’ actions, the Wikimedia Foundation said, was to use Wikipedia as a proxy for fetching data from third-party sites. In one case, the agents posted “malicious edits” that were intended to repurpose a citation tool as a proxy. In another, the agents made unsuccessful attempts to compromise the Wikipedia Etherpad note-taking tool so it would serve the same purpose.

The agents also made millions of automated API requests, crawled millions of pages, and made hundreds of thousands of queries to the Wikidata Query Service. The last action may have contributed to a partial shutdown of the query service in May, the publisher said.

Today, Rimini Street published its “2026 IT Virtualization Survey – What’s Next for VMware Users.” The survey examined 300 organizations worldwide that use VMware.

Notably, Rimini sells third-party support for VMware and other software, including Oracle and SAP. That means there’s an incentive for Rimini to portray VMware users as experiencing obstacles. However, the survey was also conducted by a third-party research company, Unisphere Research, and the results align with other recent reports about VMware customers.

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.

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.

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.

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.

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.

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.”

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.

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.

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.

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.

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.

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."

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.”

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.

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.

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.

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.

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.
