On Wednesday, a fossil-fuel lobbying group called the Washington Coal Club awarded President Trump a trophy that named him the "Undisputed Champion of Clean, Beautiful Coal." Trump took advantage of the opportunity to take his latest shot at reviving the fortunes of the US's most polluting source of electricity: an executive order that would make the military buy it.

Coal is the second most expensive source of power for the US grid, eclipsed by gas, wind, solar, hydro—everything other than nuclear power. It also produces the most pollution, including particulates that damage human lungs, chemicals that contribute to acid rain, and coal ash that contains many toxic metals. It also emits the most carbon dioxide per unit of energy produced. Prior to Trump's return to office, the US grid had been rapidly moving away from its use, including during his first term.

Despite the long-standing Republican claims to support free markets, the second Trump administration has determined that the only way to keep coal viable is direct government intervention. Its initial attempts involved declaring an energy emergency and then using that to justify forcing coal plants slated for closure to continue operations . The emergency declaration relied on what appears to be a tenuous interpretation of the Federal Power Act, and the administration was already facing a lawsuit challenging these actions.

On Tuesday night, the Federal Aviation Administration closed airspace up to 18,000 feet above the El Paso International Airport in Texas, saying the restrictions would be in place for 10 days. Then, less than 10 hours later, the federal agency reopened the airspace, allowing planes to land and take off at the busy airport.

About an hour after lifting the restrictions, US Secretary of Transportation Sean Duffy, whose responsibilities include overseeing the FAA, explained the unexpected closure by saying, "The FAA and DOW acted swiftly to address a cartel drone incursion." (The Trump Administration refers to the Department of Defense as the Department of War, or DOW, although its legal name remains the former.)

Not everyone agrees with Duffy's account.

Last May, law enforcement authorities around the world scored a key win when they hobbled the infrastructure of Lumma, an infostealer that infected nearly 395,000 Windows computers over just a two-month span leading up to the international operation. Researchers said Wednesday that Lumma is once again “back at scale” in hard-to-detect attacks that pilfer credentials and sensitive files.

Lumma, also known as Lumma Stealer, first appeared in Russian-speaking cybercrime forums in 2022. Its cloud-based malware-as-a-service model provided a sprawling infrastructure of domains for hosting lure sites offering free cracked software, games, and pirated movies, as well as command-and-control channels and everything else a threat actor needed to run their infostealing enterprise. Within a year, Lumma was selling for as much as $2,500 for premium versions. By the spring of 2024, the FBI counted more than 21,000 listings on crime forums. Last year, Microsoft said Lumma had become the “go-to tool” for multiple crime groups, including Scattered Spider, one of the most prolific groups.

Takedowns are hard

The FBI and an international coalition of its counterparts took action early last year. In May, they said they seized 2,300 domains, command-and-control infrastructure, and crime marketplaces that had enabled the infostealer to thrive. Recently, however, the malware has made a comeback, allowing it to infect a significant number of machines again.

On February 1, Robert Tinney, the illustrator whose airbrushed cover paintings defined the look and feel of pioneering computer magazine Byte for over a decade, died at age 78 in Baker, Louisiana, according to a memorial posted on his official website.

As the primary cover artist for Byte from 1975 to the late 1980s, Tinney became one of the first illustrators to give the abstract world of personal computing a coherent visual language, translating topics like artificial intelligence, networking, and programming into vivid, surrealist-influenced paintings that a generation of computer enthusiasts grew up with.

Tinney went on to paint more than 80 covers for Byte, working almost entirely in airbrushed Designers Gouache , a medium he chose for its opaque, intense colors and smooth finish. He said the process of creating each cover typically took about a week of painting once a design was approved, following phone conversations with editors about each issue's theme. He cited René Magritte and M.C. Escher as two of his favorite artists, and fans often noticed their influence in his work.

A little more than two months ago, a Rocket Lab employee called the Stennis Space Center Fire Department from the nearby A3 test stand. There was a grass fire where Archimedes engines undergo testing. Could they please send personnel over?

According to the fire station's Nov. 30 dispatcher log, the employee said, "The fire started during a test when an anomaly caused an electrical box to catch fire."

Satellite imagery from before and after the anomaly appear to show that the roof had been blown off the left test cell, one of two at the test stand at the historic NASA facility in southern Mississippi. One person with knowledge of the anomaly said, "The characterization of this as an electrical fire doesn't reflect what actually occurred. This was a catastrophic engine explosion that resulted in significant infrastructure damage."

The pre-Inca Chincha Kingdom (circa 1000-1400 CE), along Peru's southern coast, was one of the most wealthy and influential of its time before falling to the Inca and Spanish empires. Scientists have long puzzled over the foundation for that prosperity, and it seems one critical factor was bird poop, according to a new paper published in the journal PLoS ONE.

“Seabird guano may seem trivial, yet our study suggests this potent resource could have significantly contributed to sociopolitical and economic change in the Peruvian Andes,” said co-author Jacob Bongers , a digital archaeologist at the University of Sydney. “Guano dramatically boosted the production of maize (corn), and this agricultural surplus crucially helped fuel the Chincha Kingdom’s economy, driving their trade, wealth, population growth and regional influence, and shaped their strategic alliance with the Inca Empire. In ancient Andean cultures, fertiliser was power.”

Last November, Bongers co-authored a paper detailing evidence supporting the hypothesis that the mysterious "Band of Holes" on Mount Sierpe in the Andes might have been an ancient marketplace. Aerial photographs from the 1930s first revealed that long row of around 5,200 precisely aligned holes, seemingly organized into blocked sections, most likely constructed by the Chincha Kingdom. Scholars had suggested various hypotheses for what the site's purpose may have been: defense, storage, or accounting, perhaps, or maybe to collect water and capture fog for local gardens. But nobody had any strong evidence for those suggestions.

On Wednesday, former OpenAI researcher Zoë Hitzig published a guest essay in The New York Times announcing that she resigned from the company on Monday, the same day OpenAI began testing advertisements inside ChatGPT. Hitzig, an economist and published poet who holds a junior fellowship at the Harvard Society of Fellows, spent two years at OpenAI helping shape how its AI models were built and priced. She wrote that OpenAI's advertising strategy risks repeating the same mistakes that Facebook made a decade ago.

"I once believed I could help the people building A.I. get ahead of the problems it would create," Hitzig wrote. "This week confirmed my slow realization that OpenAI seems to have stopped asking the questions I'd joined to help answer."

Hitzig did not call advertising itself immoral. Instead, she argued that the nature of the data at stake makes ChatGPT ads especially risky. Users have shared medical fears, relationship problems, and religious beliefs with the chatbot, she wrote, often "because people believed they were talking to something that had no ulterior agenda." She called this accumulated record of personal disclosures "an archive of human candor that has no precedent."

Since its release in the fall of 2021 , Microsoft's Windows 11 has received an "annual feature update" in the second half of every year. These feature updates sometimes include new Windows features and other changes that are too large to roll out in a typical monthly Windows Update, and users need to upgrade to new ones to keep getting security patches and other features. The currently supported versions are Windows 11 24H2 and 25H2 , released in the fall of 2024 and 2025, respectively.

This week, Microsoft disrupted that update cadence by announcing more information on Windows 11 26H1, which is best described not as an update to Windows 11 but as another version of the operating system entirely. That's because 26H1 is a "scoped" release intended exclusively for new PCs, starting with those based on Qualcomm's recently announced Snapdragon X2 Elite chips .

Microsoft's support page explains why this release is strange: It won't be released broadly to other Windows 11 PCs, which should continue to use either 24H2 or 25H2. PCs running 24H2 or 25H2 will never be offered an update to version 26H1, though testers in the Windows Insider Program's early access Canary channel are able to install it to other PCs if they want. (Build numbers for Windows 11 26H1 start with 28000, compared to 26100 for 24H2 and 26200 for 25H2.)

Like most cloud-enabled home security cameras, Google's Nest products don't provide long-term storage unless you pay a monthly fee. That video may not vanish into the digital aether right on time, though. Investigators involved with the high-profile abduction of Nancy Guthrie have released video from Guthrie's Nest doorbell camera—video that was believed to have been deleted because Guthrie wasn't paying for the service.

Google's cameras connect to the recently upgraded Home Premium subscription service. For $10 per month, you get 30 days of stored events, and $20 gets you 60 days of events with 10 days of the full video. If you don't pay anything, Google only saves three hours of event history. After that, the videos are deleted, at least as far as the user is concerned. Newer Nest cameras have limited local storage that can cache clips for a few hours in case connectivity drops out, but there is no option for true local storage. Guthrie's camera was reportedly destroyed by the perpetrators.

Expired videos are no longer available to the user, and Google won't restore them even if you later upgrade to a premium account. However, that doesn't mean the data is truly gone. Nancy Guthrie was abducted from her home in the early hours of February 1, and at first, investigators said there was no video of the crime because the doorbell camera was not on a paid account. Yet, video showing a masked individual fiddling with the camera was published on February 10 .
