The new Chevrolet Equinox EV is a solid entry into the compact crossover market, and with a (just) sub-$35,000 starting price, it also counts as affordable by the standards of 2026. But if you think that's too rich for your blood, or that the Equinox is still too large for your needs, take heart—the Chevrolet Bolt is back in dealerships now as well.

The Bolt was GM's first modern electric vehicle, following on from the hand-built, pre-lithium ion EV1 and the compliance car that was the Spark EV. We're big fans of the Bolt here at Ars Technica. It offered well more than 200 miles of range in a mass-produced EV at a reasonable price well before Tesla's Model 3 started clogging up our roads, it got more efficient over time, and it managed to be fun to drive in the process.

General Motors (which owns Chevrolet) probably feels less well-disposed toward the Bolt. It lost thousands of dollars on each car it sold, even before the entire fleet had to be recalled for a costly battery replacement . The issue was due to improperly folded tabs on some cells that could cause a battery fire, giving GM ( and its battery partner LG ) plenty of bad press in the process. That recall alone cost $1.8 billion.

Older adults can dramatically reduce the amount of ultraprocessed foods they eat while keeping a familiar, balanced diet—and this shift leads to improvements across several key markers related to how the body regulates appetite and metabolism. That’s the main finding of a new study my colleagues and I published in the journal Clinical Nutrition .

Ultraprocessed foods are made using industrial techniques and ingredients that aren’t typically used in home cooking. They often contain additives such as emulsifiers, flavorings, colors, and preservatives. Common examples include packaged snacks, ready-to-eat meals, and some processed meats. Studies have linked diets high in ultraprocessed foods to poorer health outcomes .

My team and I enrolled Americans ages 65 and older in our study, many of whom were overweight or had metabolic risk factors such as insulin resistance or high cholesterol. Participants followed two diets low in ultraprocessed foods for eight weeks each. One included lean red meat (pork); the other was vegetarian with milk and eggs. For two weeks in between, participants returned to their usual diets.

Two historic NASA test facilities used in the development of the Saturn V and space shuttle launch vehicles have been demolished after towering over the Marshall Space Flight Center in Alabama since the start of the Space Age.

The Propulsion and Structural Test Facility, which was erected in 1957—the same year the first artificial satellite entered Earth orbit—and the Dynamic Test Facility, which has stood since 1964, were brought down by a coordinated series of implosions on Saturday (Jan. 10). Located in Marshall's East Test Area on the US Army's Redstone Arsenal in Huntsville, the two structures were no longer in use and, according to NASA, had a backlog of $25 million in needed repairs.

"This work reflects smart stewardship of taxpayer resources," said Jared Isaacman, NASA administrator, in a statement . "Clearing outdated infrastructure allows NASA to safely modernize, streamline operations and fully leverage the infrastructure investments signed into law by President Trump to keep Marshall positioned at the forefront of aerospace innovation."

CES 2026 took place in Las Vegas last week, and as usual, we're looking at the most interesting monitors from the show. Not every display is a monitor in the strictest sense, but they all provide a display for computers and have a unique twist that make them worth exploring.

It was a pretty safe bet that Dell would announce new UltraSharp monitors at CES. The displays are a solid recommendation for reliable USB-C monitors, including for Mac users and people needing something polished for professional or creative work. In recent years, UltraSharp monitors have also boasted more modern features, including integrated web cameras and IPS Black tech .

This year, the strategy was clear: Bigger is better.

In 2024, scientists announced the discovery of a new species of giant anaconda in South America. A National Geographic camera crew was on hand for the 2022 expedition that documented the new species—and so was actor Will Smith, since they were filming for NatGeo's new documentary series, Pole to Pole with Will Smith . Now we can all share in Smith's Amazon experience, courtesy of the three-minute clip above.

Along with venom expert Bryan Fry, we follow Smith's journey by boat with a team of indigenous Waorani guides, scouring the river banks for anacondas. And they find one: a female green anaconda about 16 to 17 feet long, "pure muscle." The Waorani secure the giant snake—anacondas aren't venomous but they do bite—so that Fry (with Smith's understandably reluctant help) can collect a scale sample for further analysis. Fry says that this will enable him to determine the accumulation of pollutants in the water.

That and other collected samples also enabled scientists to conduct the genetic analysis that resulted in the declaration of a new species: the northern green anaconda ( Eunectes akayama, which roughly translates to "the great snake"). It is genetically distinct from the southern green anaconda ( Eunectes murinus ); the two species likely diverged some 10 million years ago. The northern green anaconda's turf includes Venezuela, Colombia, Suriname, French Guyana, and the northern part of Brazil.

Since 2018, a group of researchers from around the world has crunched the numbers on how much heat the world’s oceans are absorbing each year. In 2025, their measurements broke records once again, making this the eighth year in a row that the world’s oceans have absorbed more heat than in the years before.

The study, which was published Friday in the journal Advances in Atmospheric Science, found that the world’s oceans absorbed an additional 23 zettajoules’ worth of heat in 2025, the most in any year since modern measurements began in the 1960s. That’s significantly higher than the 16 additional zettajoules they absorbed in 2024. The research comes from a team of more than 50 scientists across the United States, Europe, and China.

A joule is a common way to measure energy. A single joule is a relatively small unit of measurement—it’s about enough to power a tiny lightbulb for a second, or slightly heat a gram of water. But a zettajoule is one sextillion joules; numerically, the 23 zettajoules the oceans absorbed this year can be written out as 23,000,000,000,000,000,000,000.

As age-verification laws continue to dismantle the adult industry—and determine the future of free speech on the internet —a Utah lawmaker proposed a bill this week that would enforce a tax on porn sites that operate within the state.

Introduced by state senator Calvin Musselman, a Republican, the bill would impose a 7 percent tax on total receipts “from sales, distributions, memberships, subscriptions, performances, and content amounting to material harmful to minors that is produced, sold, filmed, generated, or otherwise based” in Utah. If passed, the bill would go into effect in May and would also require adult sites to pay a $500 annual fee to the State Tax Commission. Per the legislation, the money made from the tax will be used by Utah’s Department of Health and Human Services to provide more mental health support for teens.

Musselman did not respond to a request for comment.

SpaceX today received US permission to launch another 7,500 second-generation Starlink satellites, bringing its total authorization to 15,000 Gen2 satellites including those previously approved.

"Under this grant, SpaceX is authorized to construct, deploy, and operate an additional 7,500 Gen2 Starlink satellites, bringing the total to 15,000 satellites worldwide," the Federal Communications Commission announced today. "This expansion will enable SpaceX to deliver high-speed, low-latency Internet service globally, including enhanced mobile and supplemental coverage from space."

The FCC gave SpaceX permission for the first set of 7,500 satellites in December 2022 . The agency deferred action on the rest of the second-generation constellation at the time and limited the first batch to certain altitudes, saying it needed to "address concerns about orbital debris and space safety" before approving the full bunch.

It took a while, but a consensus has emerged in Europe that the continent's space industry needs to develop reusable rockets. How to do it and how much to spend on it remain unresolved questions.

Much of the discourse around reusable rockets in Europe has focused on developing a brand new rocket that might eventually replace the Ariane 6, which debuted less than two years ago but still uses the use it and lose it model embraced by the launch industry for most of the Space Age.

The European Space Agency (ESA) is offering money to emerging rocket companies in Europe to prove their small satellite launchers can do the job. ESA is also making money available to incentivize rocket upgrades to haul heavier cargo into orbit. ESA, the European Commission, and national governments are funding rocket hoppers to demonstrate vertical takeoff and vertical landing technologies. While there is significant money behind these efforts, the projects are not unified, and progress has been slow.
