Much of what we know about how a brain makes decisions comes from studying monkeys watching dots. In a task known as a random-dot-motion task, a cloud of flickering specks drifts weakly in one direction while the subject tries to determine whether—and in which direction— it’s moving. The task has shown that in the primate neocortex, neurons gather visual evidence over time, with their firing rates climbing until they cross a threshold, when the animal commits to a decision.

But avian brains don’t have a neocortex, so it wasn’t obvious how they made similar decisions.

“This was the big question,” said Andreas Nieder, a neurobiologist at the University of Tübingen. “How [would] a differently organized avian brain encode decisions?”

Intel gets waiver after worries fuzzy US ban on foreign-made robots may hit fabs

Intel gets waiver after worries fuzzy US ban on foreign-made robots may hit fabs

fivenewscrypto    octobre 25, 2026   

US chip champion Intel was so confused by the US government ban on foreign-made robots that it requested and received a waiver “out of an abundance of caution.” The tech company wanted to make sure that it could continue using certain robotic vehicles in its US chip fabs.

The uncertainty surrounding the Federal Communications Commission ban on certain foreign-made robots was revealed in the agency’s decision to grant Intel’s waiver request. On October 22, the FCC published its order allowing Intel to continue using the foreign-made robots in US semiconductor manufacturing facilities for a period of one year.

The robots in question are automated guided vehicles operating on “tracks or predefined paths” while often requiring operator oversight, according to Intel’s website. They help to move materials and items around within warehouses and factory floors.

RFK Jr.’s vaccine injury clinic could damage NIH hospital, board warns

RFK Jr.’s vaccine injury clinic could damage NIH hospital, board warns

fivenewscrypto    octobre 25, 2026   

At a recent meeting of the board that oversees the National Institutes of Health's Clinical Center Research Hospital, chair Jack Leslie opened with cheerful introductions and gregarious chatter—then diverted from the agenda of the regularly scheduled meeting. He spent the next six minutes delivering a pointed rebuke of Health Secretary Robert F. Kennedy, warning that his anti-vaccine activities could tarnish the venerable hospital, often called the "house of hope" for patients with rare conditions or those who have exhausted all other options.

Leslie took issue with a recent stunt Kennedy had pulled at the hospital, which involved making a surprise appearance for a ribbon-cutting ceremony to open his signature vaccine injury clinic. The ceremony included a panel with people claiming to have been injured by vaccines. They sat behind placards reading "vaccine injured" and spoke with Kennedy and other high-ranking Trump administration officials.

Leslie prefaced his comments by noting that some might prefer he not speak out against Kennedy's efforts. "But I think that that would be a failing as an advisory board if we were silent," he said. Leslie also noted that he has no concerns about studying potential injuries from vaccines. "Serious reactions are rare, but real," he said, and people who believe they've been injured should "be taken seriously."

Knicks sent employees fake offer of championship rings in phishing test: Report

Knicks sent employees fake offer of championship rings in phishing test: Report

fivenewscrypto    octobre 25, 2026   

The New York Knicks organization sent employees a phishing email promising free championship rings in a test of its staff's ability to detect scams, The New York Times reported yesterday. “Congratulations, your Employee Championship Ring is here,” the email sent in late September said, instructing employees to click a link to make a selection from two ring designs.

Madison Square Garden employees who clicked that link "were forced to attend a mandatory cybersecurity class to help satisfy some of [owner James] Dolan’s growing cybersecurity concerns," the report said, citing team sources. Dolan is the owner of the Knicks, the New York Rangers, and Madison Square Garden.

It's common for corporations to send phishing emails to find out which employees don't pay attention to clues that an email is a scam. A cybersecurity-test email often appears to be from the company itself but includes telltale signs of phishing. For example, Ars Technica owner Condé Nast sends phishing-test messages from email addresses with a misspelled domain, "condenest.com."

Everybody panic: A Valve developer said "HLX" in public

Everybody panic: A Valve developer said "HLX" in public

fivenewscrypto    octobre 25, 2026   

Gamers still hoping against hope for a true follow-up to Half-Life 2 (after so, so many years) may remember last year's flurry of speculation that Half-Life 3 was finally nearing completion. Amid all those rumors, though, we never got any official sign from anyone inside Valve that a Half-Life project was currently in development.

That changed this week thanks to an apparent slip-up during a panel at GameSoundCon, an industry conference devoted to "the art, technology, and business of game audio." In a panel devoted to Valve's use of open audio engines (captured in this Vimeo clip), Valve composer and audio artist Mike Morasky let an interesting string of three letters slip while talking about the way the company implements high dynamic range (HDR) audio:

Our HDR system is basically that's one of the three pieces that come together to make an HDR that you can easily optimize. And in fact, I think Deadlock has their own version of HDR. HLX has its own version, so on and so forth [emphasis added].

"HLX," of course, has been widely reported as the internal code name for Valve's next Half-Life project. The codename has shown up in Valve engine code since at least 2024, but it has never been referenced in public by a Valve employee until now (though Morasky was responsible for a close call in an interview last year).

The reactor meant to showcase nuclear’s comeback keeps hitting problems

The reactor meant to showcase nuclear’s comeback keeps hitting problems

fivenewscrypto    octobre 25, 2026   

US regulators have issued a warning to a nuclear project critical to Donald Trump’s efforts to revive the industry, after a contractor fell into a reactor cavity and a bundle of fuel rods nearly tipped over during refueling.

The US Nuclear Regulatory Commission told Holtec International, a company racing to reopen a shuttered reactor at the Palisades nuclear power plant in Michigan, to address a “chilled work environment” that has made staff hesitant to raise safety concerns without fear of retaliation.

The warning has prompted concerns among critics that financial and political pressures to revitalize nuclear power as an answer to booming AI-driven energy demand are increasing risks of accidents.

Ukraine learns to fight without Starlink as Musk plays politics with satellites

Ukraine learns to fight without Starlink as Musk plays politics with satellites

fivenewscrypto    octobre 24, 2026   

Elon Musk’s Starlink satellite service has played a pivotal role in supporting Ukraine’s successful resistance to Russia’s full-scale invasion for years. But with Starlink having become increasingly unreliable due to Musk’s political inclinations and the latest surprise disruptions to service in Ukraine, the Ukrainians and Europe as a whole are now facing urgent questions about how to move forward without it.

As the world’s largest communications satellite network, Starlink can typically support high-speed Internet and data streams for any user or vehicle equipped with a relatively compact Starlink terminal. This has enabled Ukraine to maintain vital communications for both civilian purposes and military operations—and has also expanded the Ukrainian military’s capability to remotely control or provide guidance to drones used in both air defense against Russian attacks and for striking back at Russian targets.

“Starlink currently offers some of the best satellite coverage available, with virtually no competitors when you consider the combination of cost, availability, and ease of use,” according to the head of hardware R&D at the Ukrainian defense company BlueBird Tech, who provided comments to Ars anonymously for security reasons. “In practical terms, the main limitation is the need to position the antenna so it can receive signals from the satellites.”
