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.”

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.

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.

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."

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.

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.

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 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.”

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.

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.

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."

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.
