Is Your Iced Coffee Making You Dehydrated in the Summer Heat? I Asked the Experts

As the summer sun beats down, we should all stay hydrated, as dehydration can increase our risk of heat exhaustion and heat stroke. However, when I saw the National Weather Service in Las Vegas advising residents across parts of California, Nevada and Arizona to stop drinking caffeine in extreme heat to prevent dehydration, I wondered if that was taking things too far. To find out whether caffeine actually causes dehydration to the point where you need to put your iced coffee down, I consulted

DOCSIS 3.0 vs. 3.1 vs. 4.0: How Are They Different?

If you have cable internet, then you're using DOCSIS technology. DOCSIS stands for Data Over Cable Service Interface Specifications, and it's a standard that defines how your modem relays cable internet signals to and from your home. If you have cable internet from Cox, Spectrum, Xfinity or a regional cable internet provider like Armstrong, you're using a DOCSIS-compliant modem. The DOCSIS 4.0 cable modem is ideal since it produces faster upload speeds. But while specifications for DOCSIS 4.0 h

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

X Data Center Fire in Oregon Started Inside Power Cabinet, Authorities Say

A recent, hours-long fire at a data center used by Elon Musk’s X may have begun after an electrical or mechanical issue in a power system, according to an official fire investigation. WIRED was the first to report on the blaze, which occurred on May 22 in Hillsboro, Oregon. Data center giant Digital Realty operates the 13-acre site, and multiple people familiar with the matter previously told WIRED that the Musk-run social platform X has servers there. Data center fires are rare, with about tw

Both also co-created, and work as executive pro

Tokyo's retro shotengai arcades are falling victim to gentrification

Tsutomu Nishiwaki raises the shutters of his store, the rattle marking the start of a new day at a shopping arcade in Tokyo. He wheels a display case into the foreground and stands behind the counter, framed by a sign proclaiming that this is a family-run noodle store. It is a ritual Nishiwaki has been performing almost daily for 60 years. But like the fresh noodles its owner makes every morning, the store has a limited shelf life: in a few years from now, the 80-year-old will pull down the shu

10% Off Canon Promo Code & Coupons

Normally we think the Canon EOS R8 is the best deal, but when you can save $500 on an EOS R5 C Body, why not upgrade? The R5 offers a 45 Megapixel Full-frame sensor and can shoot 8K RAW Video. It’s a powerhouse of a camera and a steal at this price. If you don’t need the huge 45 MP sensor of the R5, the smaller, cheaper R6 Mark II Body is also available for $100 off.

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

A brief history of primary coding languages

Plenty of great apps have been created using the Mac’s scripting languages, but commercial developers have largely relied on compiled languages used and supported by Apple for app and system development. Over the years those have included Object Pascal, C/C++, Objective-C and most recently Swift. This article provides a brief overview of how those changed. Lisa Clascal (1984-86) Following Apple’s use of UCSD Pascal on Apple II computers, when the Lisa was being developed its primary language w

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

Gemini with Deep Think achieves gold-medal standard at the IMO

The International Mathematical Olympiad (“IMO”) is the world’s most prestigious competition for young mathematicians, and has been held annually since 1959. Each country taking part is represented by six elite, pre-university mathematicians who compete to solve six exceptionally difficult problems in algebra, combinatorics, geometry, and number theory. Medals are awarded to the top half of contestants, with approximately 8% receiving a prestigious gold medal. Recently, the IMO has also become a

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. Ars does not accept paid editorial content. First-generation high-performance electric vehicles, like the Tesla Model S Plaid, had a party trick that would wow first-timers: straight-line acceleration. Feeling your internal organs shift under the G forces of acceleration is cool the first few times but gets annoying

Google Teases Pixel 10 Ahead of August Reveal

Google has lifted the curtains on the Pixel 10, its flagship phone for 2025, via a short clip posted on the Google Store homepage on Monday. The Pixel 10 will likely be fully revealed at a Made by Google event in New York on Aug. 20. The teaser video simply shows the back of the device with the Pixel's prominent oval-shaped camera bar, along with a flash and sensor of some sort. It follows a similar design to past Pixels, but whereas the Pixels 6, 7 and 8 all had camera bars that ran edge-to-ed

The special hell of Bolt, Europe's Uber clone

I was in Latvia a few weeks ago. Riga’s one of the Europeans cities without a good transit link from the airport into city. Snooping around online, I found that the recommended way to get a ride was the use of an app called Bolt, a European clone of Uber. I realize now that I didn’t actually check that Uber wasn’t available in Latvia, but I’m not against experimenting with a new app here and there. I used it twice to get to and from the city center, and it worked perfectly. Neither of my driver

Trump’s Commerce Secretary Loves Tariffs. His Former Investment Bank Is Taking Bets Against Them

Cantor Fitzgerald, a financial services company led by the sons of US Commerce Secretary Howard Lutnick, is creating a way for investors to bet that President Donald Trump’s signature tariffs will be struck down in court. Traders at the firm’s investment banking subsidiary, Cantor Fitzgerald & Co., say they have the capacity to buy the rights to hundreds of millions of dollars in potential refunds from companies who have paid Trump’s tariffs, according to documents viewed by WIRED. Lutnick ran

The Ending of ‘I Know What You Did Last Summer’ Changed Weeks Before Release

Filmmakers love to tinker with their movies until the last possible second. A nip here, a tweak there, change the sound, the levels, etc. But, eventually, the studios need a finished movie so it can be sent to theaters, screened for press, etc. This week’s new horror film, I Know What You Did Last Summer, had tinkering too, but it was even closer to release and more impactful to the story than most other movies. In fact, the entire ending of the movie flipped on its head mere weeks before coming

FCC to eliminate gigabit speed goal and scrap analysis of broadband prices

The Federal Communications Commission is ditching Biden-era standards for measuring progress toward the goal of universal broadband deployment. The changes will make it easier for the FCC to give the broadband industry a passing grade in an annual progress report. FCC Chairman Brendan Carr's proposal would give the industry a thumbs-up even if it falls short of 100 percent deployment, eliminate a long-term goal of gigabit broadband speeds, and abandon a new effort to track the affordability of

Flickering lights? Blown breakers? Your home needs more power - here's what to do

PM Images/Getty The hair dryer routinely trips the breaker and kills power to the second floor. The kitchen lights dim when you run the microwave. The air conditioner can only cool one room at a time on a sweltering night. You don't have adequate power in your house to support your daily needs; we've all been there. These examples might be nostalgic for some, but if you can relate in your current living situation, you might be stuck at a CORE level 1 power-constrained state. Beyond the inconv

Here Comes the Pain From Trump’s Tariffs

As Donald Trump has given the automotive industry whiplash with his tariffs, which have, at different periods, applied to cars and car parts or haven’t applied at all. While it was hard to tell how the import tax would hit auto manufacturers, the impact is starting to look more concrete, and it ain’t pretty. As CNBC notes, Stellantis, the maker of Jeep, Dodge, Fiat, Chrysler, and Peugeot, warned on Monday that it’s expecting to lose about $2.6 billion this quarter due to Trump’s tariffs, accordi

T-Mobile Upgrades Network With L4S to Improve Video Calls and Cloud Gaming

If you’re a T-Mobile customer, you may have noticed that your FaceTime calls have gotten smoother. That’s because the carrier announced today that it’s rolling out support for a new tech called Low Latency, Low Loss, Scalable Throughput (L4S) across its 5G Advanced network. T-Mobile says it’s the first U.S. wireless provider to deploy L4S at scale, and it’s promising a noticeable boost to video calls and cloud gaming. L4S works by helping your phone or device stay ahead of network congestion b

Here’s why there are so few new cars for under $30,000

The affordability crisis affecting the US automobile market shows little signs of abating. The average price of a new car continues to rise: In June the average new vehicle MSRP was $51,124, according to Kelly Blue Book, with average transaction prices a little lower at $48,907. While one might imagine this has had a dampening effect on car sales, the opposite is true—the first half of 2025 has seen a robust market with some months seeing extremely high volumes. But most signs point to a tighten

Experimental surgery performed by AI-driven surgical robot

Intuitive Surgical, an American biotechnology company, introduced DaVinci surgical robots in the late 1990s, and they became groundbreaking teleoperation equipment. Expert surgeons could operate on patients remotely, manipulating the robotic arms and their surgical tools based on a video feed from DaVinci’s built-in cameras and endoscopes. Now, John Hopkins University researchers put a ChatGPT-like AI in charge of a DaVinci robot and taught it to perform a gallbladder-removal surgery. Kuka sur
