In a recent Nature study, Stoliker’s team designed an experiment to test whether these directions are truly chaotic and random. Researchers gathered 62 people who had never taken a psychedelic before, gave them 19 milligrams of psilocybin, a common psychedelic found in certain fungi, and scanned their brains. Then, they used AI to analyze the drugged and sober brain scans. What emerged was not exactly chaos.

An uninterrupted trip

Stoliker thinks chaos is not a satisfactory explanation for psychedelics’ effect on the brain. “It never really explained why an individual would have a meaningful experience, why they might have insight, why they might experience clarity, and why these might translate into positive psychological changes,” Stoliker says. To investigate if there are other explanations, he and his colleagues designed a study called PsiConnect.

In a recent Science Advances study, a team of Spanish archaeologists has cataloged 597 wooden remains from Neanderthal living areas dating from 62,000 to 40,000 years ago. They found spears, digging sticks, bark trays, parts of shelters, and a club unlike anything seen before, suggesting Neanderthals were likely much more than just Homo sapiens’ dumber cousins.

Beyond hunting gear

The oldest wooden artifacts we have are mostly weapons. They include spears from a German town called Schöningen, a spear tip from Clacton-on-Sea in England, and the spear found alongside an elephant skeleton in Lehringen, Germany. Most came from waterlogged sediments, where a lack of oxygen slowed decay.

The Ukrainian drones struck Yandex data centers in the Sasovo and Kaluga regions of Russia on October 8 and October 9, according to Reuters. Those actions came as a direct response to a Russian drone strike campaign targeting Ukraine’s data centers, which has disrupted mobile phone and Internet services for thousands of Ukrainians since late September.

“We continue to respond to Russia’s attacks on Ukraine, and we’re doing so with high precision,” said Ukrainian President Volodymyr Zelenskyy in a post on X. “Another data center was hit as well—our symmetrical response.”

Mac Minis from over a decade ago might not seem like the obvious first choice for building a cluster supercomputer, but when networked together, the developers can orchestrate the 64 active processing cores into a combined 1.3 teraflops of performance in their most recent tests. The museum reportedly achieved 1.5 teraflops previously using all 70 available cores, prior to one node going offline. Benchmarks were obtained using a custom matrix-multiplication Python script. Five PCs are quad-core i7s, and the remaining 25 are dual-core i5 models. Except for two units from 2014, the rest of the array dates to 2012.

The replica is a valuable tool for museum-goers to understand the shifts in computer architecture since 1976. The original Cray-1 used vector processing, applying a single instruction to multiple data elements simultaneously, whereas the replica distributes work across independent processors in a parallel cluster. The peak theoretical performance of the original Cray-1 was approximately 160 megaflops. What was originally a purpose-built research machine has been re-created with consumer hardware that's vastly more capable than the machine that inspired it.

In a cover letter accompanying the 360-page "request for proposals," NASA stated its plan: "This will ensure NASA has a sustained human presence in LEO for crew members to perform science and exploration." Several private companies that have worked for years on designing and developing such stations have been keen to learn exactly what capabilities NASA is seeking. These new documents finally provide some answers.

NASA's solicitation can be found here. Industry responses are due back to NASA on December 8. NASA said it plans to select "two or more" contractors in this phase of the competition, and intends to make a final decision in April.

Right now, we're not sure what powers them. However, thanks to a recent set of eruptions at the Kilauea volcano, we have some of the best documentation yet of erupting lava fountains. In a recent edition of Science, researchers from the US Geological Survey describe what we've seen and compare it with what we might expect based on our best ideas about what powers these fountains of molten rock.

Years of fountains

With three active volcanic regions that engage in fountaining, there has been a steady flow of dramatic videos of red-hot molten rock spouting from the Earth. But Kilauea has had only three fountaining episodes since 1823, even though it's the youngest and most active volcano in Hawaii. That activity has led to intensive study, and we have a good idea of the volcano's structure. Previous work has identified a couple of lava residues within a few kilometers of the surface, and the volcano had 35 separate data-gathering stations set up on Kilauea, including "seismic, infrasound, geodetic, gas, and visual and thermal cameras."

A recent study of actual coding practices across hundreds of firms finds that human code review forms a significant "bottleneck" for the overall efficiency of AI coding tools, resulting in "little evidence that firms increase software output or reduce employment" by using them. Any efficiency increased during the actual coding phase, the study authors find, is "absorbed by downstream constraints in the production process"; as "the code review process significantly increases in length, pull requests are more likely to require revisions, and reviewers leave more comments."

Cut once, measure twice

To come to these conclusions, Harvard University researchers Fiona Chen and James Stratton made use of aggregated analytics data from Jellyfish, which measures the granular output of engineering teams. That data encompasses 300 million individual "work events" (e.g., commits and pull requests) and issue management software data across more than 700,000 employees at over 700 relevant software development firms from 2021 through March of 2026.

The trial was suspended in January after its unethical design came to light and drew international outcry. Although the trial is still halted, staff of the CDC director's office told the agency's budget office in late September to set aside $1.6 million to fund the trial, according to a report by Rolling Stone. The money was to be pulled from funding for the CDC's global health security programs, which might otherwise go toward efforts like combating the Ebola outbreak currently raging in the Democratic Republic of the Congo.

The Department of Health and Human Services, which oversees the CDC, did not respond to a request for comment from Ars Technica.

Last month we covered the winner of Nikon's Small World in Motion video: Ning Xu of Tsinghua University in China, whose video captured tiny cilia beating in the airways of a child with a rare respiratory disorder. But allegations surfaced about Xu's use of AI while making the video. Nikon launched an investigation and concluded that Xu's entry did not comply with competition rules. The new winner is Nguyen Nam Nhat of Vietnam with a video of a tiny roundworm and a single-celled organism (above).

Founded in 2011, the Nikon Small World in Motion competition is a spinoff of the company’s Small World Photomicrography Competition, which has been around since 1974. Both are meant “to showcase the beauty and complexity of things seen through the light microscope”—one through still photographs, the other through photovideography, taking advantage of all the technological advances that now allow users to make movies or time-lapse images through the microscope.

The other winners also moved up a notch with Xu's disqualification. Benedikt Pleyer of Bavaria, Germany, placed second with a video of jellyfish larvae suspended in water droplets; Andrew Moore of Howard Hughes Medical Institute in the US placed third with a video of synchronized cell division in neighboring cells; Patrick Hickey of Hypha Research Ltd. in Edinburgh, Scotland, placed fourth with a video of the dynamics of mitochondria and chloroplasts in Turtle Vine leaf cells; and Igor Adameyko placed fifth with a video of a tiny, colorful sea slug (Cyerce kikutarobabai) on the move.

Continuing Debian's community-driven ethos, the artwork submission process mirrors that of previous releases. The artwork must feel distinctively "Debian," integrate cleanly without the need for core software patching, and remain visually appealing for the long term.

Elise Couper's "Ceratopsian" theme was chosen as the winning default for Debian 13 Trixie. For anyone who might not be up on the latest from the Toy Story franchise, the release names echo character names from the animated films. Trixie was a triceratops introduced in Toy Story 3, hence the "Ceratopsian" wink in the winning submission. It makes sense that the next version of Debian continues this trend with Forky, a character introduced in the franchise's fourth entry. The Debian team cautions against overly busy designs that may cause user fatigue, but if anyone can successfully incorporate Forky's googly eyes into the design somehow, know that you'd at least win the contest for my Debian desktop wallpaper.

SpaceX will buy up to 14 megahertz of spectrum in the 800 MHz band from investment firm Grain Management, which bought the spectrum rights from T-Mobile earlier this year. T-Mobile had obtained the spectrum when it bought Sprint in 2020 and was required to sell the licenses under a merger condition imposed by the US government.

"This prime low-band spectrum addresses one of the key remaining technical gaps that will pave the way for Starlink Mobile to become a major mobile carrier in the US," SpaceX said yesterday. SpaceX this week also received US approval to launch 15,000 satellites for an upgraded version of its mobile service that it says will be far more powerful than the current offering.

Dropping the numerical and adopting the moniker of VW’s big seller is a statement. “The Tiguan is our best-selling model worldwide, and the ID.4 and ID.5 are among our most successful electric cars. The ID. Tiguan brings these two success stories together,” said Thomas Schäfer, CEO of the VW brand.

VW was an early pioneer of using flexible vehicle architectures to create a multitude of bodystyles and sizes with common parts, and its transition into building EVs hasn’t changed that. The ID. Tiguan uses an updated version of the company’s mass-market EV platform, now called MEB+, with either 58 kWh or 77 kWh battery packs. The smaller pack is only available with a 187 hp (140 kW) rear electric motor, but the 77 kWh battery can be had with either a 281 hp (210 kW) rear-wheel drive powertrain or as a 295 hp (220 kW) all-wheel drive version. Range is up to 373 miles (600 km), at least according to the European WLTP test.

Her letter said Trump Mobile also doesn't appear to have submitted a required plan for fighting robocalls. Trump Mobile's key business partner, Liberty Mobile Wireless, did make a robocall database filing, but it was not complete, Hassan said.

Hassan's letter raised questions about Trump Mobile's security related to a report that hackers stole personal data of 3,615 customers and Trump Mobile's previous confirmation that a vendor it uses exposed customers' personal data on the Internet. Hassan alleged that Trump Mobile failed to follow multiple FCC filing rules that are supposed to help ensure the security of mobile services.

“To say Margaret Hamilton was a pioneer—to say she was ahead of her time—would be a dramatic understatement. She was a software engineer at a time when that field was in its infancy, and she not only developed advanced code herself but also led a team in using that nascent technology to develop one of the most complex systems humanity had ever achieved,” said Olivier de Weck, interim head of the MIT Department of Aeronautics and Astronautics. “The Apollo program still stands as one of our greatest testaments to the power of collaboration, ingenuity, and engineering, and Hamilton was a fundamental contributor to that program’s success.”

Born in 1936 in Paoli, Indiana, Hamilton graduated from Earlham College in 1958 with a degree in mathematics and a minor in philosophy—the latter a nod to her father (a poet) and grandfather (a headmaster). She married her first husband, James Cox Hamilton, that same year. The plan was for her to work until he finished his law degree, after which he would support her through graduate school to earn a PhD in mathematics.
