Month: April 2025

The Internet might look a bit different on Android soon. Last month, Google announced its intent to make Chrome for Android a more immersive experience by hiding the navigation bar background. The promised edge-to-edge update is now rolling out to devices on Chrome version 135, giving you a touch more screen real estate. However, some websites may also be a bit harder to use.

Moving from button to gesture navigation reduced the amount of screen real estate devoted to the system UI, which leaves more room for apps. Google's move to a "dynamic bottom bar" in Chrome creates even more space for web content. When this feature shows up, the pages you visit will be able to draw all the way to the bottom of the screen instead of stopping at the navigation area, which Google calls the "chin."

Radio signal broadcasts have their usefulness, but they eventually end (except, perhaps, for SETI). Every so often, we mark the public end of a once-essential wavelength, such as 3G cellular, analog television, or the Canadian time check. One of the most weirdly useful signals will soon end in the United Kingdom, with notable consequences if its transition is not properly handled.

Beginning in the early 1980s, UK homes could have electrical meters installed with a radio teleswitch attached. These switches listened for a 198 kHz signal from the BBC's Radio 4 Long Wave service, primarily broadcast from the powerful Droitwich Transmitting Station. These switches listened to 30 messages per minute, waiting for a certain 50-bit data packet to arrive that signaled that electricity was now at cheaper, off-peak rates ("tariffs" in the UK).

With this over-the-air notice, homes that bought into Economy 7 or Economy 10 (7 or 10 hours of reduced-price power) could make use of ceramic-stuffed storage heaters that stayed warm into the day, prepare hot water heaters, and otherwise make use of off-peak power. How the electrical companies, BBC, and meters worked together is fascinating in its own right and documented in a recent video by Ringway Manchester (which we first saw at Hackaday).

Despite a recent pause on some tariffs, Apple remains in a particularly thorny spot as Donald Trump's trade war spikes costs in the tech company's iPhone manufacturing hub, China.

Analysts predict that Apple has no clear short-term options to shake up its supply chain to avoid tariffs entirely, and even if Trump grants Apple an exemption, iPhone prices may increase not just in the US but globally.

The US Trade Representative, which has previously granted Apple an exemption on a particular product, did not respond to Ars' request to comment on whether any requests for exemptions have been submitted in 2025.

Kevin Peterson is a "nose" for his own perfume company, Sfumato Fragrances, by day. By night, Sfumato's retail store in Detroit transforms into Peterson's craft cocktail bar, Castalia, where he is chief mixologist and designs drinks that pair with carefully selected aromas. He's also the author of Cocktail Theory: A Sensory Approach to Transcendent Drinks, which grew out of his many (many!) mixology experiments and popular YouTube series, Objective Proof: The Science of Cocktails.

It's fair to say that Peterson has had an unusual career trajectory. He worked as a line cook and an auto mechanic, and he worked on the production line of a butter factory, among other gigs, before attending culinary school in hopes of becoming a chef. However, he soon realized it wasn't really what he wanted out of life and went to college, earning an undergraduate degree in physics from Carleton College and a PhD in mechanical engineering from the University of Michigan.

After 10 years as an engineer, he switched focus again and became more serious about his side hobby, perfumery. "Not being in kitchens anymore, I thought—this is a way to keep that little flavor part of my brain engaged," Peterson told Ars. "I was doing problem sets all day. It was my escape to the sensory realm. 'OK, my brain is melting—I need a completely different thing to do. Let me go smell smells, escape to my little scent desk.'" He and his wife, Jane Larson, founded Sfumato, which led to opening Castalia, and Peterson finally found his true calling.

The Federal Trade Commission now has three commissioners, and all of them are Republicans.

The FTC historically had a 3–2 partisan split, with the president's party having a one-seat advantage. But President Trump fired FTC Democrats Alvaro Bedoya and Rebecca Kelly Slaughter last month, and the Senate yesterday confirmed Trump nominee Mark Meador to the agency's third Republican spot.

The Senate vote was 50–46 and went along party lines. "I respect Mr. Meador's qualifications and his prior experiences... But I cannot support the confirmation of any additional members to the FTC until Commissioner Slaughter and Commissioner Bedoya are reinstated," Sen. Amy Klobuchar (D-Minn.) said yesterday. "President Trump's dismissal of Commissioners Slaughter and Bedoya is not only illegal; it hurts consumers and small businesses by undermining the independence of the Agency that Congress established to protect consumers from fraud, scams, and monopoly power. An independent FTC is critical for protecting consumers and has done so in a bipartisan manner for over 110 years."

Professionelles Penetration Testing erfordert mehr als Standardwissen. Ein fünftägiger Online-Workshop bereitet gezielt auf die CPENT-Zertifizierung vor, inklusive eigener Exploits und realitätsnaher Szenarien. (Golem Karrierewelt, Sicherheitslücke)

Concerns about AI's energy use have a lot of people looking into ways to cut down on its power requirements. Many of these focus on hardware and software approaches that are pretty straightforward extensions of existing technologies. But a few technologies are much farther out there. One that's definitely in the latter category? Quantum computing.

In some ways, quantum hardware is a better match for some of the math that underlies AI than more traditional hardware. While the current quantum hardware is a bit too error-prone for the more elaborate AI models currently in use, researchers are starting to put the pieces in place to run AI models when the hardware is ready. This week, a couple of commercial interests are releasing a draft of a paper describing how to get classical image data into a quantum processor (actually, two different processors) and perform a basic AI image classification.

All of which gives us a great opportunity to discuss why quantum AI may be more than just hype.

The booming popularity of Ozempic and other GLP-1 drugs for weight loss has led to a flurry of companies vying to make new and improved anti-obesity medications.

One of those is Boston-based Syntis Bio, which is working on a daily pill that mimics the effects of gastric bypass—no actual surgery required. Today, the company announced early data from animals and a small group of human volunteers showing that its approach is safe and may be able to suppress hunger. The company presented the findings Thursday at the European Congress on Obesity and Weight Management.

“We're at a stage with obesity treatment where it's important for us to figure out, how do we now tune it to be more effective?” says Rahul Dhanda, Syntis Bio’s CEO and cofounder.
