Ars staffers share some of their favorite unexpected 3D prints

Part of the fun of 3D printing is discovering just how many possibilities there are for different things to print. Obviously, they're fun for printing toys or decorations that you couldn't or wouldn't buy yourself, but they're also powerful problem-solving tools. Once you've solved a few problems with 3D printed parts, you start looking around for other minor inconveniences or quality-of-life upgrades that you could solve—and the breadth and depth of the 3D printing community means that you can

Wildfires are challenging air quality monitoring infrastructure

Ten years ago, Tracey Holloway, an atmospheric scientist at the University of Wisconsin–Madison, would have said that air pollution in the United States was a huge success story. “Our air had been getting cleaner and cleaner almost everywhere, for almost every pollutant,” she said. But in June 2023, as wildfire smoke from Canada spread, the air quality dropped to historically low levels in her home state of Wisconsin. Just last month, the region’s air quality dipped once more to unhealthy level

9 Best Prime Day Fitness Tracker Deals and Smart Ring Sales (2025)

In the northern hemisphere, it's hard to not spend the winter in a state of slumbering sloth, just waiting for sunshine and good times to start again.

‘People Are Going to Die’: A Malnutrition Crisis Looms in the Wake of USAID Cuts

Few lifesaving tools are as effective as ready-to-use therapeutic foods, known as RUTFs, which are specially designed to treat severe malnutrition and often resemble fortified peanut butter. Despite announcing a $50 million pledged to fund RUTFs earlier this summer, the Trump administration's deep cuts to foreign assistance have wreaked havoc on RUTF distribution globally, and the State Department hasn’t placed orders with leading suppliers this year. Experts say the disruptions will result in m

6 Amazon Prime Day Mattress and Bedding Deals on Our Favorite Gear (2025)

A Giant Planet and a Small Star Are Shaking Up Conventional Cosmological Theory

Many of the stars in the Milky Way galaxy are small, dim red dwarfs—stars much smaller than the sun in both size and mass. TOI-6894, located far away from Earth, is one of them. Astronomers previously thought a star like this could not have large planets circulating it, because its mass is only about 20 percent of the sun, meaning its planetary system—generated from materials surrounding the star—would not have contained enough mass to form a giant body like Saturn or Jupiter. But when observi

China Has Attempted What Might Be the First-Ever Orbital Refueling of a Satellite

Two Chinese satellites have rendezvoused with one another more than 20,000 miles above the Earth in what analysts believe is the first high-altitude attempt at orbital refueling. China’s Shijian-21 and Shijian-25 satellites, known as SJ-21 and SJ-25 for short, likely docked together in geosynchronous orbit sometime last week. This is the conclusion of multiple civilian satellite trackers using open source imagery showing the two satellites coming together, then becoming indistinguishable as a s

Thread count: Ikea is stitching together a smarter home

Ikea is relaunching its smart home line in a move that will make its low-cost products work with other brands, with or without Ikea’s own hub. Starting in January, the Swedish furniture giant will release more than 20 new Matter-over-Thread smart lights, sensors, and remotes with “more new product types and form factors to come,” David Granath of Ikea of Sweden, tells The Verge in an exclusive interview.

Activision pulls Call of Duty game after PC players are hacked

Activision has taken one of its Call of Duty games down from the Microsoft Store and PC version of Game Pass, reportedly because multiple PC players had their computers compromised by hackers after playing the title.

Springer Nature book on machine learning is full of made-up citations

Would you pay $169 for an introductory ebook on machine learning with citations that appear to be made up?

Introduction to Indian English

Content In less than 200 years since its formal introduction as part of a nascent and westernized education system, English has grown to be the medium through which the people of India communicate with the world, and often with one another. In large parts of a country with several major languages, it vies with Hindi—the most commonly used Indian language—as the spoken language of choice. There is a range of ability from a mere smattering of words, to some amount of rudimentary communication, to

US Court nullifies FTC requirement for click-to-cancel

A federal appeals court today struck down a "click-to-cancel" rule that would have required companies to make cancelling services as easy as signing up. The Federal Trade Commission rule was scheduled to take effect on July 14 but was vacated by the US Court of Appeals for the 8th Circuit. A three-judge panel ruled unanimously that the Biden-era FTC, then led by Chair Lina Khan, failed to follow the full rulemaking process required under US law.
