MONACO—The idea of an "entry-level" supercar might sound like a contradiction in terms, but every car company's range has to start somewhere, and in McLaren's case, that's the Artura. When Ars first tested this mid-engined plug-in hybrid in 2022 , It was only available as a coupe. But for those who prefer things al fresco , the British automaker has now given you that option with the addition of the Artura Spider.

The Artura represented a step forward for McLaren. There's a brand-new carbon fiber chassis tub, an advanced electronic architecture (with a handful of domain controllers that replace the dozens of individual ECUs you might find in some of its other models), and a highly capable hybrid powertrain that combines a twin-turbo V6 gasoline engine with an axial flux electric motor.

More power, faster shifts

For model year 2025 and the launch of the $273,800 Spider version, the engineering team at McLaren have given it a spruce-up, despite only being a couple of years old. Overall power output has increased by 19 hp (14 kW) thanks to new engine maps for the V6, which now has a bit more surge from 4,000 rpm all the way to the 8,500 rpm redline. Our test car was fitted with the new sports exhaust, which isn't obnoxiously loud. It makes some interesting noises as you lift the throttle in the middle of the rev range, but like most turbo engines, it's not particularly mellifluous.

As some Ars readers may recall, I reviewed The Maven Cargo e-bike earlier this year as a complete newb to e-bikes. For my second foray into the world of e-bikes, I took an entirely different path.

The stylish Maven was designed with utility in mind—it's safe, user-friendly, and practical for accomplishing all the daily transportation needs of a busy family. The second bike, the $4,299 Mod Easy Sidecar 3 , is on the other end of the spectrum. Just a cursory glance makes it clear: This bike is built for pure, head-turning fun.

The Mod Easy 3 is a retro-style Class 2 bike—complete with a sidecar that looks like it's straight out of Indiana Jones and the Last Crusade . Nailing this look wasn't the initial goal of Mod Bike founder Dor Korngold. In an interview with Ars, Korngold said the Mod Easy was the first bike he designed for himself. "It started with me wanting to have this classic cruiser," he said, but he didn't have a sketch or final design in mind at the outset. Instead, the design was based on what parts he had in his garage.

W hen Ina Chung, a Colorado mother, first fed packaged foods to her infant, she was careful to read the labels. Her daughter was allergic to peanuts, dairy, and eggs, so products containing those ingredients were out. So were foods with labels that said they may contain the allergens.

Chung felt like this last category suggested a clear risk that wasn’t worth taking. “I had heard that the ingredient labels were regulated. And so I thought that that included those statements,” said Chung. “Which was not true.”

Precautionary allergen labels like those that say "processed in a facility that uses milk" or "may contain fish" are meant to address the potential for cross-contact. For instance, a granola bar that doesn’t list peanuts as an ingredient could still say they may be included. And in the United States, these warnings are not regulated; companies can use whatever precautionary phrasing they choose on any product. Some don’t bother with any labels, even in facilities where unintended allergens slip in; others list allergens that may pose little risk. Robert Earl, vice president of regulatory affairs at Food Allergy Research & Education, or FARE , a nonprofit advocacy, research, and education group, has even seen such labels that include all nine common food allergens. “I would bet my bottom dollar not all of those allergens are even in the facility,” he said.

The Ocean Sciences Building at the University of Washington in Seattle is a brightly modern, four-story structure, with large glass windows reflecting the bay across the street.

On the afternoon of July 7, 2016, it was being slowly locked down.

Red lights began flashing at the entrances as students and faculty filed out under overcast skies. Eventually, just a handful of people remained inside, preparing to unleash one of the most destructive forces in the natural world: the crushing weight of about 2½ miles of ocean water.

I recently tried to use a Raspberry Pi 5 as a regular desktop PC . The experiment wasn't a failure—I was able to use a Pi to get most of my work done for a few days. But the device's performance, and especially the relative immaturity of the Linux's Arm software ecosystem, meant that there were lots of incompatibilities and rough edges.

One of the problems with trying to use a Pi 5 as a regular desktop computer is that, by the time you've paid for the 8GB version of the board, a decent active cooler and case, and (ideally) some kind of M.2 storage attachment and SSD, you've spent close to a couple of hundred dollars on the system. That's not a ton of money to spend on a desktop PC, but it is enough that the Pi no longer feels miraculously cheap, and there are actually other, more flexible competitors worth considering.

Consider the selection of sub-$200 mini desktop PCs that litter the online storefronts of Amazon and AliExpress. Though you do need to roll the dice on low-to-no-name brands like Beelink, GMKTec, Firebat, BMax, Trigkey, or Bosgame, it's actually possible to buy a reasonably capable desktop system with 8GB to 16GB of RAM, 256GB or 512GB of storage, a Windows 11 license, and a workaday x86-based Intel CPU for as little as $107, though Amazon pricing usually runs closer to $170.

When Chuck Yeager reached Mach 1 on October 14, 1947, the entire frame of his Bell X-1 aircraft suddenly started to shake, and the controls went. A crew observing the flight in a van on the ground reported hearing something like a distant, rolling thunder. They were probably the first people on Earth to hear a boom made by a supersonic aircraft.

The boom felt like an innocent curiosity at first but soon turned into a nightmare. In no time, supersonic jets—F-100 Super Sabers, F-101 Voodoos, and B-58 Hustlers—came to Air Force bases across the US, and with them came the booms. Proper, panes-flying-off-the windows supersonic booms. People filed over 40,000 complaints about nuisance and property damage caused by booming jets, which eventually ended up with the Federal Aviation Administration imposing a Mach 1 speed limit for flights over land in 1973.

Now, NASA wants this ban to go. It has started the Quesst mission to go fast over American cities once more. But this time, it wants to do it quietly.

Your keyboard is the thread that connects you to your computer. The way a keyboard feels—from the sensations of each key pressing down and resetting to the build of the board’s chassis—has a direct impact on your typing experience, affecting accuracy, speed, and fatigue.

We’ve dug into the joys of quality keyboards and the thrills of customization at Ars Technica before. But what really makes one type of keyboard feel better than another? People say membrane keyboards feel mushy, but why ? And what about keyboards with cult-like followings? What makes decades-old IBM keyboards or expensive Topres so special?

In this guide, we’ll look at how some of the most popular keyboard categories work and how their differences impact typing feel.

The Super Mario Maker community and "Team 0%" have declared victory in their years-long effort to clear every user-submitted level in the original Wii U game before the servers shut off for good on April 8 . That victory declaration comes despite the fact that no human player has yet to clear "Trimming the Herbs" (TTH), the ultra-hard level that gained notoriety this month as what was thought to be the final "uncleared" level in the game.

This strange confluence of events is the result of an admission by Ahoyo, the creator of Trimming the Herbs, who came clean Friday evening regarding his use of automated, tool-assisted speedrun (TAS) methods in creating the level. That means he was able to use superhuman capabilities like slow-motion, rewinding, and frame advance to pre-record the precise set of perfectly timed inputs needed to craft the "creator clear" that was necessary to upload the level in the first place.

"I’m sorry for the drama [my level] caused within the community, and I regret the ordeal," Ahoyo wrote on the Team 0% Discord and social media . "But at least it was interesting. However in the end the truth matters most. Congratulations to Team 0% for their well-earned achievement!"

Sports cars have always been emotionally driven purchases, and perhaps no automaker understands this better than Porsche. There are more than two dozen iterations of the 911 on sale today, and while it can sometimes feel like sussing out the differences in character between one variant and another is an exercise in splitting hairs, the new Sport Classic tugs at enthusiasts' heartstrings in a way that no other modern 911 can.

Part of the Heritage Design Edition series, which includes a 911 Targa as well as two more as-yet-unnamed models, the new Sport Classic leverages the formidable capability of the latest 911 Turbo while delivering a genuinely unique driving experience and a distinct sense of style.

While its purposeful stance comes courtesy of the Turbo's widened body, elements like the bespoke carbon fiber hood, the Carrera GT-inspired carbon “double bubble” roof, and the eye-catching carbon fiber ducktail rear spoiler—the latter of which pays homage to the iconic 911 Carrera RS 2.7 of the early 1970s—help to provide the Sport Classic with a look all its own. The bodywork is also further differentiated from its Turbo sibling thanks to the deletion of the side intakes, a change that necessitated new tooling to stamp the unique panels that run from underneath the front of the doors all the way to the rear bumper. New inlets installed under the ducktail spoiler are on hand to channel air into the engine's intake system.
