GMC's Hummers have always been divisive. After getting hold of the rights to a civilian version of the US military vehicle in 1999, the company set about designing new, smaller vehicles to create an entire range. The ungainly H2 and H3 followed, both SUVs playing to the sensibilities of a country grappling with its warlike nature. By 2010, the Hummer brand was dead and laid dormant until someone had the bright idea to revive it for the electric vehicle generation. We drove the pickup version of that new Hummer in 2022, now it's time for the $104,650 Hummer EV SUV.

I'll admit I was worried that the Hummer EV wasn't going to fit in my parking space. This is an extremely large vehicle, one that's classified as a class 3 medium-duty truck—hence the yellow lights atop the roof. In fact, at 196.8 inches (5,000 mm) long, it's actually slightly shorter than the pickup version, although that length doesn't count the big spare tire hanging off the back.

Its 86.5-inch (2,196 mm) width just about fit between the lines, although it was a tight squeeze to try to open a door and climb up into the Hummer if my neighbor was parked as well. And climb up you do—there's 10.2 inches (259 mm) of ground clearance even in the suspension's normal setting, and the overall height is a towering 77.8 inches (1,976 mm). There is an entry mode that drops the car on its air springs by a couple of inches, but only if you remember to engage the feature when you park.

A Cargo Dragon spacecraft docked to the International Space Station on Tuesday morning, less than a day after lifting off from Florida.

As space missions go, this one was fairly routine, ferrying about 6,000 pounds (2,700 kg) of cargo and science experiments to the space station. Over the course of nearly a dozen years, this was the 31st cargo supply mission that SpaceX has flown for NASA to the orbiting laboratory.

However, there is one characteristic of this flight that may prove significant for NASA and the future of the space station. As early as Friday, NASA and SpaceX have scheduled a "reboost and attitude control demonstration," during which the Dragon spacecraft will use some of the thrusters at the base of the capsule. This is the first time the Dragon spacecraft will be used to move the space station.

More than 33,000 Boeing workers reached a tentative agreement Monday night to end a weekslong strike that quickly became one of the costliest strikes in recent history—estimated to have cost the US economy more than $9.6 billion.

Through their unions, International Association of Machinists and Aerospace Workers (IAM) Districts 751 and W24, workers in Washington state, Oregon, and California had previously rejected two inadequate Boeing offers while the company lost hundreds of millions daily. Negotiations had stalled until US Secretary of Labor Julie Su stepped in, IAM said in a press release, helping to restart talks and get to a deal that 59 percent of workers could agree on.

Under the proposed deal, workers will receive a 43 percent wage increase over four years, as well as a $12,000 bonus they can choose to receive in their paycheck, as a 401(k) contribution, or a combination of both. Additionally, Boeing agreed to match 401(k) contributions up to 8 percent.

Metal Slug Tactics pushes hard on the boundaries of the vaunted run-and-gun arcade series. You can run when it's your character's turn, but it's a certain number of tiles. You can gun, but not rapidly, and only after considering the most optimal target and tools.

Is this just Into the Breach with classic-era SNK artwork and aesthetics? Kind of, and you're welcome.

As a true fan once wrote, Metal Slug games are about "crazy vehicles, amusing enemies and levels, and some of the best sprite art you'll ever see in gaming." To my eyes, you're getting a whole bunch of that in Tactics. Turn-based, grid-mapped tactics have a natural tendency to feel slow and to strip characters down to chess pieces that can do two or three things. Here, the characters and villains cannot stop rocking their bodies, the guns and explosions and scimitars go off big, and the exaggerated-just-enough artwork keeps everything locked into an action-movie mood.

An ongoing attack is uploading hundreds of malicious packages to the open source node package manager (NPM) repository in an attempt to infect the devices of developers who rely on code libraries there, researchers said.

The malicious packages have names that are similar to legitimate ones for the Puppeteer and Bignum.js code libraries and for various libraries for working with cryptocurrency. The campaign, which was active at the time this post was going live on Ars, was reported by researchers from the security firm Phylum. The discovery comes on the heels of a similar campaign a few weeks ago targeting developers using forks of the Ethers.js library.

Beware of the supply chain attack

“Out of necessity, malware authors have had to endeavor to find more novel ways to hide intent and to obfuscate remote servers under their control,” Phylum researchers wrote. “This is, once again, a persistent reminder that supply chain attacks are alive and well.”

The Food and Drug Administration is warning consumers not to use any drugs made by a compounding pharmacy in California after regulators realized the pharmacy was making drugs that need to be sterile—particularly injectable drugs—without using sterile ingredients or any sterilization steps.

The products made by the pharmacy, Fullerton Wellness LLC, in Ontario, California, include semaglutide, which is intended to mimic brand-name weight-loss and diabetes drugs Wegovy and Ozempic. Fullerton also made tirzepatide, which is intended to mimic weight-loss and diabetes drugs Zepbound and Mounjaro.

The FDA became aware of the problem after a patient submitted a complaint to the regulator that a vial of semaglutide from Fullerton Wellness had an unidentified "black particulate" floating in it. Semaglutide, like tirzepatide, is injected under the skin and is intended to be sterile.

The Supreme Court will soon weigh two cases that could potentially make it harder for misled investors to sue Big Tech companies after major scandals.

One case involves one of the largest tech scandals of all time, the Facebook-Cambridge Analytica data breach. In 2019, Facebook agreed to pay "more than $5 billion in civil penalties to settle charges by the Federal Trade Commission (FTC) and the Securities and Exchange Commission (SEC) that it had misled its users and investors over the privacy and security of user data on its platform," a Supreme Court filing said.

The other case involves an allegation that Nvidia intentionally hid how much of its 2017–2018 GPU demand was due to a volatile cryptocurrency boom and not Nvidia's core gaming business—allegedly misleading investors ahead of a crypto crash. After the bust, Nvidia suddenly had to slash half a billion dollars from its earnings projection, and market experts later estimated that the firm had understated its crypto-related revenue by more than a billion. In 2022, Nvidia paid a $5.5 million SEC penalty over the inadequate disclosures that one SEC chief said "deprived investors of critical information to evaluate the company’s business in a key market."

On Friday, TriStar Pictures released Here, a $50 million Robert Zemeckis-directed film that used real time generative AI face transformation techniques to portray actors Tom Hanks and Robin Wright across a 60-year span, marking one of Hollywood's first full-length features built around AI-powered visual effects.

The film adapts a 2014 graphic novel set primarily in a New Jersey living room across multiple time periods. Rather than cast different actors for various ages, the production used AI to modify Hanks' and Wright's appearances throughout.

The de-aging technology comes from Metaphysic, a visual effects company that creates real time face swapping and aging effects. During filming, the crew watched two monitors simultaneously: one showing the actors' actual appearances and another displaying them at whatever age the scene required.

How did supermassive black holes end up at the center of every galaxy? A while back, it wasn't that hard to explain: That's where the highest concentration of matter is, and the black holes had billions of years to feed on it. But as we've looked ever deeper into the Universe's history, we keep finding supermassive black holes, which shortens the timeline for their formation. Rather than making a leisurely meal of nearby matter, these black holes have gorged themselves in a feeding frenzy.

With the advent of the Webb Space Telescope, the problem has pushed up against theoretical limits. The matter falling into a black hole generates radiation, with faster feeding meaning more radiation. And that radiation can drive off nearby matter, choking off the black hole's food supply. That sets a limit on how fast black holes can grow unless matter is somehow fed directly into them. The Webb was used to identify early supermassive black holes that needed to have been pushing against the limit for their entire existence.

But the Webb may have just identified a solution to the dilemma as well. It has spotted a black hole that appears to have been feeding at 40 times the theoretical limit for millions of years, allowing growth at a pace sufficient to build a supermassive black hole.

As I followed a friend down a flow-y, undulating single-track trail, I started laughing. Unlike my mountain bike-riding companion, I was on a gravel bike, the new Trek Checkpoint SL 7 AXS Gen 3. You might be wondering why a review of a gravel bike is starting with such a ride. The answer is simple—the Checkpoint had excelled everywhere else I rode it, so I was curious to see how it would fare on a non-technical MTB track. Amazingly well, as it turns out.

Unlike every other bike Ars has reviewed to this point, the Checkpoint SL 7 Gen 3 has no motor—there's no e- in this bike, as the only batteries are for shifting.. As is the case with our other bike reviews, sometimes we ask for a specific model, but manufacturers tend to contact us when we’ve already got a garage full of bikes we’ve not finished the reviews for (there are currently 12 bikes in my garage, some of which belong to other family members).

Launched in 2018, the Checkpoint is Trek's gravel-centric bike. For 2025, Trek has split its gravel lineup into the third-generation Checkpoint Trek and the Checkmate SLR 9 AXS. The latter features a lighter-weight frame, a power meter, and SRAM's new Red XPLR groupset. Selling for $11,999, the Checkmate is a gravel racer. Priced several thousand less at $5,699, the Checkpoint SL 7 AXS is now Trek's top gravel bike for those looking for a fun day out on the trails.

Disposable vapes are indefensible. Many, or maybe most, of them contain rechargeable lithium-ion batteries, but manufacturers prefer to sell new ones. More than 260 million vape batteries are estimated to enter the trash stream every year in the UK alone. Vapers and vape makers are simply leaving an e-waste epidemic to the planet's future residents to sort out.

To make a point about how wasteful this practice is—and to also make a pretty rad project and video—Chris Doel took 130 disposable vape batteries (the bigger "3,500 puff" types with model 20400 cells) found littered at a music festival and converted them into a 48-volt, 1,500-watt e-bike battery, one that powered an e-bike with almost no pedaling more than 20 miles. You can see the whole build and watch Doel zoom along trails on his YouTube video.

Credit: Chris Doel How the battery fits onto the bike that Chris Doel powers with vape batteries: a big bag, ratchet straps, and wiring to a rear hub motor. Just, one more time, folks: do not do this at home. Credit: Chris Doel

To be clear: Do not do this. Do not put disposable vape cartridges in a vise clamp to "pop out" their components. Do not desolder them from vape cartridges that have a surprising amount of concentration still in them. Do not wire them together using a balance board, group them using 3D-printed cell holders, and then wire them in series. Heck, do not put that much power into a rear hub on a standard bike frame, at least more than once. Doel has a fire extinguisher present and visible on his workbench, and he shows you what happens when two of the wrong batteries happen to make momentary contact—smoke, coughing, and strong warnings.

Henry VIII's favorite warship, the Mary Rose, sank in battle in 1545. Archaeologists successfully raised the ship in 1982, along with thousands of articles and the remains of 179 crew members—all remarkably well preserved thanks to the anaerobic conditions of the shipwreck created by the layers of soft sediment that accumulated over the wreckage.

A new analysis of some of the recovered bones reveals that whether someone is right- or left-handed could affect how their collarbone chemistry changes as they age, according to a new paper published in the journal PLoS ONE. This has implications for our understanding not just of aging, but of bone conditions like fracture risk and osteoarthritis.

As previously reported, the earliest-known reference to the Mary Rose appears in a January 29, 1510, letter ordering the construction of two new ships for the young king: the Mary Rose and her sister ship, dubbed the Peter Pomegranate. Once the newly built ship had launched, Henry VIII wasted no time defying his advisers and declaring war on France in 1512. The Mary Rose served the monarch well through that conflict, as well as during a second war with the French that ran roughly from 1522 through 1525, after which it underwent a substantial overhaul.

X, formerly Twitter, is now letting blocked users see posts made by the people who blocked them.

"We're starting to launch the block function update," X's engineering team wrote yesterday. X previously said that after the change, "If your posts are set to public, accounts you have blocked will be able to view them, but they will not be able to engage (like, reply, repost, etc.)."

To justify the change, X said the block functionality could previously be "used by users to share and hide harmful or private information about those they've blocked." The change will allow people who are blocked "to see if such behavior occurs... allowing for greater transparency," X said.

On Friday, S&P Dow Jones Indices announced that AI chipmaker Nvidia will replace Intel in the Dow Jones Industrial Average, marking a seismic shift in the semiconductor industry and ending Intel's 25-year run on the prestigious stock market index. The change takes effect on November 8.

"The index changes were initiated to ensure a more representative exposure to the semiconductors industry," wrote S&P in a press release.

Intel's stock has dropped 54 percent this year, making it the worst performer on the Dow, and the company now holds a market value of under $100 billion for the first time in three decades, Reuters reported. Analysts expect Intel to post its first annual net loss since 1986.

If conventional wisdom were to be believed, the car we're reviewing today should not exist. Automakers are only interested in making very big, very expensive electric vehicles, leaving nothing for people with normal-sized budgets and normal-sized needs. While it's true that those oversized EVs are overrepresented among new car launches, they aren't the only game in town. As an alternative, consider the Hyundai Kona Electric, which we last sampled in pre-pandemic times.

In fact, Kona Electric has changed quite a bit since we last drove one. Last year, an all-new model went on sale in North America, and it has carried over unchanged to its model year 2025 version. The range starts at $32,875 for the Kona Electric SE, which makes do with a 133 hp (99 kW) motor driving the front wheels, but the other trims offered—the $36,875 SEL, the $38,275 N Line (tested here), and the $41,050 Limited use a more powerful 201 hp (150 kW) motor. (All four have an identical 188 lb-ft (255 Nm) torque output.)

In terms of size and weight, the Kona Electric really is a refreshing change from EVs that are often approaching three tons. With its rear wing and slightly tweaked front, the N Line is 1.1 inches longer than the other Kona Electrics at 172.6 inches (4,384 mm) long. All Kona Electrics are 71.9 inches (1,826 mm) wide and 62 inches (1,575 mm) tall, with a 104.7-inch (2,659 mm) wheelbase. Curb weight is what counts as featherweight for an EV—3,880 lbs (1,760 kg).

When Chinese space officials unveiled the design for the country's first super heavy lift rocket nearly a decade ago, it looked like a fairly conventional booster. The rocket was fully expendable, with three stages and solid motors strapped onto its sides.

Since then, the Asian country has been revising the design of this rocket, named Long March 9, in response to the development of reusable rockets by SpaceX. As of two years ago, China had recalibrated the design to have a reusable first stage.

Now, based on information released at a major airshow in Zhuhai, China, the design has morphed again. And this time, the plan for the Long March 9 rocket looks almost exactly like a clone of SpaceX's Starship rocket.

Plans by Mark Zuckerberg’s Meta to build an AI data center in the US that runs on nuclear power were thwarted in part because a rare species of bee was discovered on land earmarked for the project, according to people familiar with the matter.

Zuckerberg had planned to strike a deal with an existing nuclear power plant operator to provide emissions-free electricity for a new data center supporting his artificial intelligence ambitions.

However, the potential deal faced multiple complications including environmental and regulatory challenges, these people said.

Tech companies are bracing ahead of the US presidential election, dreading the looming threat of more tariffs that could further restrict the flow of imports from China, no matter which candidate is elected.

Tariffs are a tax placed on imports and are intended to disrupt trade with foreign adversaries. While former President Donald Trump has frequently claimed that China pays for tariffs, in actuality, that tax is paid by US businesses and citizens any time they want to purchase a restricted good from China.

Used as a trade barrier, tariffs can place an economic burden on countries like China, but that burden is really only felt if businesses and consumers avoid importing goods. If companies cannot cost-effectively or practically switch suppliers—as is the case with China, which is a dominant global manufacturing hub in the tech industry—shrinking profit margins can trigger US businesses to spike prices for consumers.
