Nearly a month since its launch, a first-of-its-kind commercial satellite built to save NASA's Swift gamma-ray telescope from a fiery reentry is having problems of its own, the agency announced Tuesday.

The Link satellite developed by Katalyst Space Technologies "experienced issues with attitude control" over the weekend, NASA said, causing the spacecraft to spin and resulting in sporadic communications.

"Preliminary investigation shows that two of Link's three reaction wheels currently are not operable, and there is some loss of functionality in its cold gas thruster system," NASA said.

A bizarre series of events in a college microbiology lab class left 33 people—including students, professors, and lab workers—believing they were exposed to a deadly germ. Of those, 32 began taking an antibiotic regimen as a precaution to prevent a life-threatening infection. Two also underwent lumbar punctures—aka spinal taps—after developing mild symptoms.

But none of them had actually been exposed to a dangerous pathogen, a fortunate twist in the strange incident, which otherwise stands to be a cautionary tale for the ages. The incident was published in a recent issue of Morbidity and Mortality Weekly Report .

It began with a simple laboratory exercise. The microbiology lab students were supposed to be given mystery bacteria by their instructors and then identify the microbe based on a series of biochemical tests and morphological characterization.

Last week’s unprecedented security event in which two OpenAI security hacking models trespassed into the network of fellow AI company Hugging Face was enabled by exploiting one or more zero-day vulnerabilities in Artifactory, JFrog, the product’s developer, said Monday.

In an incident mimicking a dystopian sci-fi novel, two OpenAI models broke out of the restricted environment meant to keep them from accessing the Internet during an internal test, the AI company revealed last week . The models went on to breach Hugging Face’s network and steal confidential information and credentials. OpenAI said its agent achieved the feat by exploiting a previously unknown vulnerability. The company called the event “unprecedented,” and outsiders largely agreed.

Not the triumph made out to be

OpenAI said the models exploited multiple attack vectors, including stolen credentials and zero-days, to gain remote code execution capabilities, but until now, the vulnerable software was unknown. JFrog’s Monday disclosure said the product was a self-managed instance Artifactory, a repository management system that secures and streamlines customers’ software development operations. JFrog says Artifactory is used by more than 7,500 developer Teams, 80 percent of which work for Fortune 100 companies.

eBay and three former executives agreed to pay nearly $56 million in a settlement over a macabre campaign of cyberstalking and harassment that targeted two journalists in 2019.

As we've previously written , the case involved deliveries of live cockroaches, a funeral wreath, a book about surviving the loss of a spouse, and a bloody pig mask to the home of a couple who run a news website. There were also harassing messages sent via email and Twitter, and an attempt to install a GPS tracking device on the victims' car. Criminal charges resulted in guilty pleas and prison terms for former eBay employees.

The victims were Ina and David Steiner of Natick, Massachusetts, who run the news website EcommerceBytes. "David and I officially settled the lawsuit we filed in 2021 against eBay and its former executives over the stalking and harassment campaign we endured in 2019 designed to stop our reporting," Ina Steiner wrote on EcommerceBytes yesterday. "The landmark civil rights settlement includes $55.7 million in compensation and charitable commitments."

Some 66 million years ago, an asteroid impact wiped out three-quarters of all plant and animal species on Earth, most notably taking down the dinosaurs. But exactly how that impact caused those extinctions has been the subject of fierce debate. According to a new paper published in the Journal of Geophysical Research: Biogeosciences, the impact would have produced an immense cloud of dust that superheated the upper atmosphere, charbroiling living organisms unable to take shelter and igniting widespread wildfires.

As previously reported , the most widely accepted explanation for what triggered that catastrophic mass extinction is known as the “ Alvarez hypothesis ,” after the late physicist Luis Alvarez and his geologist son, Walter. In 1980, they proposed that the extinction event may have been caused by a massive asteroid or comet hitting the Earth. They based this conclusion on their analysis of sedimentary layers at the Cretaceous-Paleogene boundary (the K-Pg boundary, formerly known as the K-T boundary) found all over the world, which included unusually high concentrations of iridium—a metal more commonly found in asteroids than on Earth. (That same year, Dutch geophysicist Jan Smit independently arrived at a similar conclusion .)

Since then, scientists have identified a likely impact site: a large crater in Chicxulub, Mexico, in the Yucatan Peninsula, first discovered by geophysicists in the late 1970s. The impactor that created it was sufficiently large (between 11 and 81 kilometers, or 7 to 50 miles) to melt, shock, and eject granite from deep inside the Earth, probably causing a megatsunami and ejecting vaporized rock and sulfates into the atmosphere. It has been estimated that the impact would have released energy over a billion times higher than the atomic bombs dropped on Hiroshima and Nagasaki in 1945.

From New York to Texas , state and local governments have heard the message: Their constituents are wary of data centers . Across the political spectrum, large numbers of Americans agree that these facilities should pay taxes, cover the bill for water and power upgrades, keep noise to a minimum, and employ locals at decent wages. In other words, data centers should legitimately benefit the communities whose land and power they use.

Developers often express a willingness to do these things—until they see the specific list of requirements.

A pitched battle in the Philadelphia suburbs provides a vivid illustration of this dynamic. Developer Brian O'Neill wants to build a 2 million-square-foot data center in a former steel plant. Under Pennsylvania law, Plymouth Township (in which the plant is located) cannot simply say "no" to any lawful land use, but it can enforce zoning rules and require project mitigations in the name of health and safety.

Anyone following the AI space is by now familiar with lofty claims that AI models will soon be better than humans at everything and capable of replacing vast swaths of the human workforce . In a new study from Google Research, though, a team that looked at how workers are actually using Gemini "[did] not find evidence... to support the claims that AI is about to cause massive automation and displacement of white-collar work..."

The paper , released last week, introduces the "AI & Economy ATLAS," an Activity, Task, Landscape, and Adoption Study of 15 million anonymized AI interactions across the Gemini App, Google's AI Mode, and the Gemini API. Their initial review of the data finds that, while AI sees some significant use across a wide variety of occupations, that use "remains shallow and overwhelmingly collaborative in nature, with end-to-end task automation limited in scope."

"AI appears useful for a subset of tasks..."

To come to these conclusions, Google researchers used an automated classifier to sort work-based AI interactions using the Bureau of Labor Statistics' Standard Occupational Classifications and O*NET's more detailed database of specific work interactions . While this method required some probabilistic classification of "inherently uncertain" interactions, verification by human reviewers found it to be a reliable gauge of how Gemini prompts were being used for work.

A new Airbus passenger jet completed an ultra-long test flight between Australia and France lasting more than 24 hours—paving the way for the world’s longest nonstop commercial flights starting up next year.

The Airbus A350-1000ULR was developed specifically for Qantas Airways’ planned nonstop flights between Sydney and either New York or London. The Australian airline has ordered a dozen of the new airliners for its Project Sunrise routes that aim to start offering tickets for sale in 2027.

The aircraft had been doing initial test flights near the Airbus facilities in Toulouse, France, with a small team of test pilots and test engineers before conducting its first ultra long-haul test flight last week. After taking off from Toulouse on July 23, it flew for 19 hours and 13 minutes before landing in Melbourne, Australia, on July 24.

Minnesota, the first US state to prohibit prediction markets, was prevented from enforcing the law by a federal court ruling just days before the ban was scheduled to take effect. But while Minnesota was stopped from enforcing a total ban, the state may ultimately be allowed to prohibit some types of prediction-market wagers.

The Trump administration and the two largest prediction markets—Kalshi and Polymarket—sued Minnesota after the state enacted the law in May . The cases were consolidated, and a ruling issued yesterday imposed a preliminary injunction blocking the law that was scheduled to take effect on August 1.

Minnesota lawmakers saw prediction markets as indistinguishable from gambling, but the US Commodity Futures Trading Commission (CFTC) argues it has exclusive authority to regulate the platforms under federal law. One of the primary legal questions is whether event contracts are "swaps," which are regulated by the CFTC.
