In 2025, United Airlines will fly an air taxi service between the downtown Vertiport Chicago and O'Hare International Airport, using electric vertical takeoff and landing aircraft it is purchasing from Archer Aviation. The Archer Midnight eVTOL aircraft will complete the route in about 10 minutes; according to local resident and Ars Managing Editor Eric Bangeman, that journey by car can take over an hour due to road construction.

"Both Archer and United are committed to decarbonizing air travel and leveraging innovative technologies to deliver on the promise of the electrification of the aviation industry," said Michael Leskinen, president of United Airlines Ventures. "Once operational, we're excited to offer our customers a more sustainable, convenient, and cost-effective mode of transportation during their commutes to the airport."

United placed an order for 200 eVTOL aircraft from Archer back in 2021 at a cost of $1 billion. The startup has also raised money from the automaker Stellantis, which has been helping the company with making carbon fiber composites.

Climate change enables spread of flesh-eating bacteria in US coastal waters

Though the occurrence of infections is small, the mortality rate is as high as 18%.

Cases of a potentially fatal infection from a seawater-borne pathogen have increased off the US Atlantic coast as ocean waters warmed over the last 30 years and are expected to rise further in future because of climate change, according to a study published on Thursday by Scientific Reports, an open-access journal for research on the natural sciences and other topics.

The incidence of infections from Vibrio vulnificus, a pathogen that thrives in shallow, brackish water, was eight times greater in the Eastern US in 2018 than it was in 1988, and its range shifted northward to areas where waters were previously too cold to support it, according to the paper, “Climate Warming and Increasing Vibrio Vulnificus Infections in North America,” by academic researchers in the US, England, and Spain.

By the middle of the 21st century, the pathogen is expected to become more common in major population centers, including New York City, and by the end of the century, infections may be present in every US Atlantic coast state if carbon emissions follow a medium- to high-level trajectory, the report said.

In-car subscriptions are not popular with new car buyers, survey shows

Automakers are pushing subscriptions, but consumer interest just isn’t there.

The last decade or so has seen the creeping techification of the auto industry. Executives will tell you the trend is being driven by consumers, starry-eyed at their smartphones and tablets, although the 2018 backup camera law is the main reason there's a display in every new car.

But automakers have been trying to adopt more than just shiny gadgets and iterating software releases. They also want some of that lucrative "recurring revenue" that so pleases tech investors but makes the rest of us feel nickeled and dimed. Now we have some concrete data on just how much car buyers are asking for this stuff, courtesy of a new survey from AutoPacific. The answer is "very little."

AutoPacific asked people looking to buy a new vehicle about their interest in 11 different in-car connected features, starting with a data plan for the car for a hypothetical price of $15/month.

Dream Chaser is delayed again, raising questions about Vulcan launch plans

Is there still a path to Vulcan flying a national security mission in 2023?

United Launch Alliance's Vulcan rocket, without its payload, rolls to the launch pad for tests on March 9, 2023.

The long-awaited debut of a winged space plane will have to wait a little longer. This week NASA updated its internal schedule to show that Sierra Space's Dream Chaser spacecraft will now dock to the International Space Station no earlier than December 17, 2023.

Previously, Sierra Space had been publicly targeting a launch of Dream Chaser in August, on board United Launch Alliance's new Vulcan rocket.

In a statement to Ars, Sierra Space confirmed the delay. "Sierra Space’s plan is to complete the first launch of Dream Chaser by the end of the 4th quarter this year," the company said.

How The New York Times managed to avoid ruining Wordle

Producer says new owners were wary to monetize or make changes to the viral hit.

SAN FRANCISCO—When The New York Times acquired daily puzzle mega-hit Wordle at the beginning of 2022, there were plenty of skeptics who were sure it signaled the end of the game's incredible viral rise. Apparently, those skeptics included some of the people at the Times itself.

At a presentation at the Game Developers Conference Thursday, Times game producer and industry veteran Zoe Bell said the new owners expected Wordle's daily users "would just immediately decline" after the acquisition. Partly that was out of fear that some players would recoil from the "huge corporate behemoth" that now owned the indie hit. But it was also a simple recognition of the usual cycle for viral "zeitgeist" games: "How long can exponential growth go on?"

Just over a year after the acquisition, though, Bell said the company's efforts at "preserving Wordle as an Internet treasure" have paid off. That's thanks in large part to a patient, "first do no harm" strategy that didn't seek to directly monetize the game or introduce a lot of half-baked changes to the game's successful formula, she said.
