Newly Discovered ‘Infinity Galaxy’ Could Prove How Ancient Supermassive Black Holes Formed

A team of astronomers have discovered a curious figure in the universe. It is two distant galaxies colliding with each other to form a larger structure. From Earth’s perspective, the junction of the disks resembles the number eight lying down, similar to the infinity symbol (∞). Because of this resemblance, the researchers—who are based at the universities of Yale and Copenhagen—have nicknamed it the “Infinity Galaxy” and have detailed their discovery in a paper published in the Astrophysical J

Did Tesla’s Robotaxi Launch Backfire?

Would you consider a ride in a self-driving car? After hearing a bit about Tesla’s robotaxi launch in Austin, Texas, last month, just under half of US consumers wouldn’t even think about it, according to survey data shared exclusively with WIRED. Thirty-one percent of the survey’s respondents said they’re not considering riding one right now. Sixty-five percent said they hadn’t even heard about Tesla’s robotaxi launch, which includes just a handful of cars and is open only to invited users—most

How to Spot and Guard Against Wrong Number Scams

Something you can be sure of when it comes to scams and swindles is that the methods used to try to part you from your data, your money, or both are constantly changing—which of course makes it more difficult to spot scenarios where someone is attempting to trick you. One simple scam that's continuing to get more common starts off with text from someone who has apparently messaged the wrong number. There's no mistake though: Your number is being deliberately targeted by a fraudster. A wrong nu

Fiberglass-Free, Chemical-Free: Natural Fire Barriers for Mattresses

What do mattresses and a box of matches have in common? It's not just that they’re both rectangular—both can can be very flammable if you're not careful. Mattresses have historically posed a significant fire hazard, and they still can without careful attention to the materials used. In the US, an estimated 20,800 residential fires occurred due to mattresses and bedding igniting from flame exposure between 1996 and 1998, according to FEMA. At that time, fires involving mattresses and bedding wer

Tesla opens retro-futuristic diner as Elon Musk hints at more locations

In Brief The Tesla Diner & Drive-In, a long-awaited and hyped facility that combines retro nostalgia and futurism with the automaker’s fast-charging network, officially opened at 4:20 p.m. on Monday in Hollywood, California. The Tesla Diner & Drive-In is technically a place for Tesla drivers to charge their EVs and maybe get hamburgers, hot dogs, or other classic diner menu items (which Eater shared in full). The diner, according to Not a Tesla App, is loaded with Tesla-branded merchandise, an

Google Home is becoming a house of glitches, users say

TL;DR Google Home and Nest users are reporting a significant decline in reliability, with devices frequently misunderstanding commands or failing to respond at all. Core features like controlling lights, routines, and speaker groups seem to be breaking down. While the exact cause of the downgraded experience is unclear, users suspect upcoming Gemini updates are to blame. Google’s smart speakers and hubs appear to be steadily declining in performance. A recent Reddit thread has highlighted jus

We have made the decision to not continue paying for BBB accreditation

We have made the conscious choice not to continue paying for accreditation from the Better Business Bureau (BBB). We realize that this may raise questions among our customers, and we want to explain why we made this decision. For years, people have been told to look for BBB accredited businesses, and that it somehow reflects whether a business is on the up and up. What most don’t realize is that businesses PAY to be accredited with the BBB. You do not EARN an accreditation- you buy it. A few m

What happens when an octopus engages with art?

CNN — When the Japanese artist Shimabuku was 31 years old, he took an octopus on a tour of Tokyo. After catching it from the sea with the help of a local fisherman in Akashi, a coastal city over 3 hours away from the Japanese capital by train, he transported the live creature in a temperature-controlled tank of seawater to show it the sights of Tokyo before returning it safely to its home the same day. “I thought it would be nice,” the artist, now 56, said about the experience, over a video ca

How AI agents can generate $450 billion by 2028 - and what stands in the way

Philip Thurston/Getty Images Agentic AI is one of the fastest-emerging technologies in business, with the potential to generate $450 billion in economic value through revenue uplift and cost savings across surveyed countries by 2028, according to the Rise of agentic AI: How trust is the key to human-AI collaboration. The new report from Capgemini Research Institute reveals insights from a survey of 1,500 senior executives across 14 countries on the emergence of AI agents as a transformative for

The surprising geography of American left-handedness (2015)

A pre-K teacher in Oklahoma is making news this week after forcing a left-handed 4-year-old boy to write with his right hand. The boy was sent home from school with an article discussing left- and right-handedness. The article mentions historic attitudes toward left-handedness that associate it with evil and the devil. It's written carelessly enough that it isn't clear whether the writer believes left-handedness is still seen as evil or whether that was only the case in the past. Regardless, it

AI comes up with bizarre physics experiments, but they work

If the AI’s insights had been available when LIGO was being built, “we would have had something like 10 or 15% better LIGO sensitivity all along,” he said. In a world of sub-proton precision, 10 to 15% is enormous. “LIGO is this huge thing that thousands of people have been thinking about deeply for 40 years,” said Aephraim Steinberg, an expert on quantum optics at the University of Toronto. “They’ve thought of everything they could have, and anything new [the AI] comes up with is a demonstrati

Uv: Running a script with dependencies

A Python script is a file intended for standalone execution, e.g., with python <script>.py . Using uv to execute scripts ensures that script dependencies are managed without manually managing environments. Note If you are not familiar with Python environments: every Python installation has an environment that packages can be installed in. Typically, creating virtual environments is recommended to isolate packages required by each script. uv automatically manages virtual environments for you and

Losing language features: some stories about disjoint unions

You can give users syntactically unguarded access to union members, say by using container.field syntax, in which case all you can do if the tag doesn't match that field at runtime is to raise a runtime error, which you can at least do systematically, but the ergonomics are lousy: it's inefficient (you wind up checking twice) and it doesn't help the user avoid the runtime error by statically forcing cases to be handled. You can do #1 but then also fail to even raise a runtime error when the t

Nearly 3,000 people are leaving NASA, and this director is one of them

You can add another name to the thousands of employees leaving NASA as the Trump administration primes the space agency for a 25 percent budget cut. On Monday, NASA announced that Makenzie Lystrup will leave her post as director of the Goddard Space Flight Center on Friday, August 1. Lystrup has held the top job at Goddard since April 2023, overseeing a staff of more than 8,000 civil servants and contractor employees, and a budget last year of about $4.7 billion. These figures make Goddard the

Economist Warns the AI Bubble Is Worse Than Immediately Before the Dot-Com Implosion

For years now, certain experts have warned that the AI industry is a massive bubble waiting to burst. The enormous hype driving a market frenzy, they say, could lead to a collapse if it's exposed to be built on widespread overpromising. Most recently, Apollog Global Management chief economist Torsten Slok warned that the current AI bubble is starting to look even worse than the market conditions leading up to the dot-com implosion of the late 1990s. "The difference between the IT bubble in the

California DMV Seeking 30-Day Tesla Sale Suspension for Unrealistic 'Autopilot,' 'Full Self-Driving' Claims

The California Department of Motor Vehicles has brought suit against electric car manufacturer Tesla, alleging false advertising and misleading customers with its "Autopilot" and "Full Self-Driving" features. The DMV is angling for a 30-day suspension of the automaker's license to sell EVs in California for at least 30 days while the courts hash out whether fines or retribution should come next. Tesla is, of course, looking to fight the allegations. What does this mean for you? If the CA DMV's

Mercedes-AMG gives us a ride in its next high-performance EV

Mercedes-Benz provided flights from Detroit to Stuttgart, Germany, and accommodation so Ars could be briefed on the AMG.EA prototype as well as the GT XX that we covered last month.

Amazon and the “Profitless Business Model” Fallacy

[DISCLOSURE: As always when I write about Amazon, I'll note I worked there from 1997-2004 and that I still own some shares in the company. I still have many friends who work there, though I have no more idea what Amazon is working on now than any of you in the public.] With every quarterly earnings call, my Twitter feed lights up with jokes about how Amazon continues to grow its revenue and make no profits and how trusting investors continue to rewards the company for it. The apotheosis of that

Scholars solved a 130-year literary mystery and it hinged on one word

A medieval literary puzzle which has stumped scholars including M.R. James for 130 years has finally been solved. Cambridge scholars now believe the Song of Wade, a long lost treasure of English culture, was a chivalric romance not a monster-filled epic. The discovery solves the most famous mystery in Chaucer's writings and provides rare evidence of a medieval preacher referencing pop culture in a sermon. The breakthrough, detailed on July 15 in The Review of English Studies, involved working o

Google and OpenAI Chatbots Claim Gold at International Math Olympiad

EPA Employees Still in the Dark as Agency Dismantles Scientific Research Office

Employees of the crucial scientific research arm of the Environmental Protection Agency (EPA) have been left with more questions than answers as the agency moves to officially wind down the office following months of back-and-forth. On Friday evening, the EPA issued a press release announcing a reduction in force at the Office of Research and Development (ORD), citing the move as part of a larger effort to save a purported $748.8 million. On Monday, some employees at ORD, the largest office in
