Interesting Engineering is reporting that researchers at the University of Groningen in the Netherlands found that tin-based perovskite solar cells can slow heat loss from high-energy “hot electrons” by a factor of 1,000 and could push solar cell efficiency beyond the theoretical 33 percent limit.
When sunlight strikes a panel, photons jump-start electrons into action. The most energetic photons create super-charged hot electrons. Theoretically, these high-voltage powerhouses should generate far more electricity, but, in practice, they are fleeting. In fractions of a trillionth of a second, these high-energy particles rapidly cool, dumping their bonus energy as waste heat before ever leaving the solar cell.
“This means that the energy is lost before the hot electron exits the solar cell material,” said Jan Anton Koster, Professor of Physics of Novel Semiconductors and Devices at the University of Groningen.
Using a specialized solar cell material called tin-based perovskite, Loi’s lab performed a feat many thought impossible: she slowed the heat loss down by a factor of 1,000. Suddenly, the extra energy lingered for nanoseconds instead of vanishing in picoseconds.
The study findings were published in the journal ACS Energy Letters.

Google has been fined more than €400m (£345m) over the way it processed users’ location data, following claims that the tech giant had manipulated users into agreeing to be constantly tracked on their mobile phones. The fine, imposed by Ireland’s Data Protection Commission (DPC), comes after complaints from multiple European consumer organisations that Google was following every step users took.
The DPC launched its inquiry six years ago and set out to find out whether Google had a valid legal basis for its use of location data. It found that Google users could have been unaware that their location was being used to influence them with adverts or to gather details about their health and interests.

NFL teams are now restricted on what can be shown on stadium video boards during field-goal and extra-point attempts, per a directive from the league issued prior to the beginning of the 2026-27 season.
Teams must display a static image or a standard wide-angle, All-22 view on the jumbo-sized screens behind the end zone as kicks are taking place, the NFL mandated in a memo sent to each organization, according to ESPN.
NFL rules have always mandated that moving, flashing, blinking images and texts could not be shown on video boards during field-goal and extra-point tries. To prevent undue distractions or unfair advantages to home teams, only static images could be displayed on video boards.
However, those rules have been modified to more closely restrict even images that aren't moving on the screen, ESPN's Mike Reiss and Adam Schefter reported. The stricter regulations were implemented in response to a social-media post by a former NFL analytics coach that pointed out images displayed by the New England Patriots on the Gillette Stadium video board that presented an optical illusion to opposing place-kickers.

Among the latest round of grants from the [Bill] Gates Foundation is one for $650,000 to the National Governors Association (NGA) Center for Best Practices, the stated purpose of which is "to equip governors with knowledge and resources to guide K-12 education policy related to artificial intelligence."
The grant aligns nicely with the Gates Foundation's Monday announcement that it is betting big on AI to boost global health, agriculture and education, starting with a $1 billion "down payment", 40% of which is earmarked for education. It also comes amid a pushback against the use of AI in K-12 in schools, including moratoriums on K-12 generative AI use in the nation's two largest cities, New York City and Los Angeles.
If Gates' push for the nation's Governors to drive K-12 AI policy seems a bit familiar, it may be because Bill Gates was among the so-called CEOS for CS, a who's who of tech leaders whose Code.org-organized PR campaign led to the nation's Governors signing of a compact committing to expand K-12 CS education (including a CS graduation requirement) in their states at the NGA's Summer 2022 Meeting. Ironically, the massive post-COVID tech company layoffs soon followed and after that came the job-disrupting breakout of generative AI, which prompted the tech-backed nonprofit Code.org (who subsequently rebranded as CodeAI) to round up 250+ CEOs for another PR campaign in 2025, this time calling upon state education leaders and policymakers to pivot and further commit to making AI education available for every student as part of a push for 'policy solutions that ensure every student has access to the foundational skills needed to succeed in a world enabled by AI.'
As Yogi Berra might say, "It's déjà vu all over again!"

The Guardian is reporting, along with others, that President Donald Trump is proferring a new argument for building his triumphal arch in Washington DC: it will be converted into a “top grade military complex” replete with drone and ammunition storage space and customized sniper facilities on the roof and plaza.
In a post on his Truth Social platform on Sunday morning, Trump claimed that his new plan came at the “strong request” of the US military. He said the 250ft structure would be able to “house, store, and have the rapid ability to use large quantities of sniper ammunition in storage”. The president added, “There will be no facility like this anywhere in the world.”
This seems like a ploy to get around courts holding up the project by re-framing the project as a National Security matter, as he did with the East Wing of the White House. (Can the Kennedy Center be far behind?)

Elon Musk’s bogus voter registration website is collecting extensive user data and selling it.
The website was funded by Musk and is operated by America PAC, a conservative political action committee founded in 2024 to support Donald Trump’s presidential campaign.
The VoteSafe.org website has been promoted as a way for Americans to register to vote and check their registration ahead of the November midterm elections.
But MeidasTouch and Snopes found that despite presenting itself as a voter-registration resource, the site doesn’t actually register users to vote.
The site's privacy policy says America PAC can collect information, including:
Users' names
Dates of birth
Addresses
Email addresses
Phone numbers
IP addresses
Location
Information about how they interact with the site
It also permits the collection of "inferences" about users, including their preferences, characteristics, behavior, attitudes, and psychological tendencies.
The policy says the information may be shared with or sold to business partners for targeted marketing.

From Stanford Medicine:
"For centuries, scientists have thought of the brain as a single, unified organ. But new research led by Stanford Medicine reveals that what we call the brain is two distinct organs that evolved independently over hundreds of millions of years."
The adult brain has three main regions: the forebrain, midbrain and hindbrain. Scientists could never create hindbrain neurons.
"Previous attempts to make hindbrain neurons likely tried to coax forebrain and midbrain progenitors into hindbrain cells, which our study shows is not possible,” said researcher Rayyan Jokhai.
"The researchers’ breakthrough came from studying the earliest moments of embryonic development, during a stage called gastrulation when the body first takes shape. Jokhai and Dundes discovered that the hindbrain follows a separate developmental path, running in parallel to — rather than branching off from — the pathway that creates the forebrain and midbrain."
With this knowledge, researchers were able to create hindbrain neurons.

The Federal Communications Commission yesterday approved Paramount Skydance's plan to sell large equity stakes to the sovereign wealth funds of Saudi Arabia, the United Arab Emirates, and Qatar.
Under US law, companies with licenses to run broadcast stations need FCC approval to have direct or indirect foreign ownership exceeding 25 percent of the company's stock. Paramount says its indirect foreign ownership will reach 49.5 percent after it receives investments from the sovereign wealth funds and filed a petition asking the FCC to waive the foreign ownership limit.
Paramount, the owner of CBS, holds FCC licenses for the 28 local CBS stations that it owns and operates. Paramount is buying Warner Bros. Discovery in a $111 billion deal that is being partially financed with foreign investment but hasn't completed the acquisition because US states filed a lawsuit that aims to block the merger. Trump's Department of Justice approved the merger.
The FCC is letting Paramount sell indirect ownership stakes to "some of the most repressive governments in the world," FCC Commissioner Anna Gomez, the only Democrat on the commission, said yesterday. "An investment this large in one of America's biggest media companies doesn't just buy equity, it secures influence over what gets said and what gets made."

The lowly fruit fly just beat one of the worldâ(TM)s most advanced AI models at chess.
Thatâ(TM)s just one of dozens of wild experiments that have gone viral since scientists fully mapped the neural pathways of an adult male fruit fly â" whose entire brain fits on the head of a pin â" and posted the data online.
The threshold-crossing technology, achieved by HHMI Janelia Research in Virginia and Google Research, catalogued all 166,000 individual neurons and 25.6 million connections in the flyâ(TM)s brain and made it downloadable on Sept 3.
Inventive nerds then used the digitized neural network to power and navigate a wide variety of contraptions, apps and games.
Creator Maxime Labonne hooked the mapped pathways up to a chess engine and pitted it against Claude Opus 5, which is one of the most advanced AI models on the market.
The fly delivered a checkmate in just 11 moves.

In experiments involving living cells, mouse tissues, and isolated mitochondria, the team detected an unusual vibration that appeared only while mitochondrial structures remained intact.
A model linked the vibration to a possible quantum interaction. When researchers illuminated cells with selected infrared frequencies, the cells produced 10 percent more ATP.
Together, the results suggest mitochondria may contain a quantum state that influences cellular energy production.

CNN is reporting that an AI hallucination of Chinese nuclear components almost led to US military attack on a Chinese ship.
The intelligence report, circulated across the US military this spring in the midst of the war with Iran, immediately set off alarm bells: A Chinese ship in the Middle East was transporting components of a nuclear weapons program.
The US military swung into action with plans to intercept the vessel, according to four sources familiar with the episode. According to two of the sources, armed members of the US military were preparing to board the ship. Military planes were in the air, one of those sources and another source familiar with the incident said.
It was only just before the planned operation that officials dug deeper into the report put together by a special operations command analyst and found it had been generated with the help of artificial intelligence (AI) — and that a chatbot the analyst had used inaccurately identified the material the ship was carrying. CNN was not able to learn what the misidentified cargo was.
The report, according to one of the sources, was “entirely false.” But it also “almost started a war,” the source said. Any US operation against a Chinese vessel could have risked spiraling into an armed conflict between the two nations.
The kind of “hallucination” that the tool used by the analyst in this case conjured has not been an isolated incident across the intelligence community since these tools began proliferating across government, according to one of the sources.

During the annual Air Force Association Air, Space, and Cyber Conference outside Washington D.C., senior U.S. military officials publicly acknowledged on-orbit weapons in orbit and laid out the need to be prepared for conflict out to cislunar space. In a speech to senior US Air Force and US Space Force officers, allied officers, and senior defense industry officials, Air Force Secretary Troy Meink acknowledged the orbital weapons in a speech, saying “Today, we continue to ensure we remain ready to meet the challenges of evolving threats wherever they exist... This is why the United States now has, on orbit, space-control weapons, capable of defending the joint force against hostile adversaries.” In a separate speech, General Dan Caine, Chairman of the Joint Chiefs of Staff, acknowledged the expanding battlefield the U.S. military must be prepared to fight in: “Our task, my friends, is to adapt right now, so the Joint Force is prepared to fight, endure, and win, in global contested environments, from the seabed to cislunar space."
One article notes that "while top Space Force officials have provided few details about how U.S. forces would fight between the Earth and its moon, they have been vocal about adding sensors and capabilities to watch adversary movements there." Aaron Brynildson, a professor of space law at the University of Mississippi notes that US military officials are motivated by peer competitor activities, particularly China. “There’s a fear that recent Chinese activity on the moon and in cislunar space might outpace the United States,” Brynildson said. “China has a relay satellite in cislunar space and is performing robotic missions on the far side of the moon.” Lt. Gen. Gregory Gagnon, the head of Combat Forces Command at US Space Force, acknowledges that concern, saying “Our adversaries, our potential adversaries, such as the PRC, are actively pursuing activities in the cislunar parts of space. So that's sort of the expansion, if you will, of I would say the end zone, if you will, in the football game..."
Brynildson raises concerns about the current ambiguity around the lack of laws and policy governing space weapons. “It’s unclear what the legal restraints on the use of kinetic or non-kinetic weapons in space might be. The Outer Space Treaty doesn’t give us great answers to what factors a military action must consider,” he said. “The DoD Law of War Manual is also non-committal on the unique aspects of the space domain. At a minimum, general principles from the law of armed conflict would apply, such as only striking military-related satellites, avoiding collateral damage to civilians, etc... Ultimately, I think the first space conflict might be the time when most of these rules get written."

A new J.D. Power study suggests traditional cable and satellite TV may not be dying as quickly as many expected. Overall customer satisfaction with cable and satellite providers increased 18 points year over year on a 1,000 point scale, while satisfaction with live TV streaming declined three points to 627. Verizon Fios ranked highest among traditional providers with a score of 586, while YouTube TV led live TV streaming with 643.
Streaming still has a big advantage on price. J.D. Power found live TV streaming costs $41 less per month on average, and it holds a 99 point advantage for value satisfaction. Still, rising streaming prices and increasingly fragmented services may be changing the equation. The study surveyed 33,137 customers between August 2025 and July 2026. Is cord cutting still the obvious choice it once seemed to be?

Details remain limited, and researchers caution against assuming a “rogue AI” scenario. Still, the incident raises a consequential question for defenders: as attackers use agents to plan, execute, and adapt at machine speed, will traditional human-led detection and response remain fast enough?
