How to clear your iPhone cache (and why you should do it before installing iOS 26 public beta)

zdnet.com Elyse Betters Picaro 2025-07-30 23:52:00

What is cache? Cache -- or browser cache -- is the temporary storage of website files. So, things like images, scripts, and cookies that your browser saves on your phone to make pages load faster the next time you visit. Also: Every iPhone model that can be updated to iOS 26 (and which ones don't support it) Over time, though, those files can add up, taking a large bite out of your device storage and slowing things down. That's why it's smart to clear your browser cache regularly. In this art

Diet, not lack of exercise, drives obesity, a new study finds

You can't outrun a bad diet. Food — not lack of exercise — fuels obesity, study finds toggle caption PCH-Vector/iStockphoto via Getty Images Back in the 1800s, obesity was almost nonexistent in the United States. Over the last century, it's become common here and in other industrialized nations, though it remains rare among people who live more traditional lifestyles, such as the Hadza hunter-gatherers of Tanzania. So what's changed? One common explanation is that as societies have developed,

Electric cars produce less brake dust pollution than combustion-engine cars

“It’s not just the tailpipe y’all,” joked one Electrek commenter, alluding to the black discolorations on alloy wheels visible proof of a less infamous city pollutant: brake dust. For decades, exhaust emissions have been the focus of city-air cleaning initiatives, but a new wave of research indicates that the real story goes far beyond the muffler.

Two narratives about AI

news.ycombinator.com Study Hacks 2025-07-30 22:08:09

I want to present you with two narratives about AI. Both of them are about using this technology to automate computer programming, but they point toward two very different conclusions. The first narrative notes that Large Language Models (LLMs) are exceptionally well-suited for coding because source code, at its core, is just very well-structured text, which is exactly what these models excel at generating. Because of this tight match between need and capability, the programming industry is ser

Major Quantum Computing Advance Made Obsolete by Teenager (2018)

news.ycombinator.com Kevin Hartnett 2025-07-30 22:42:25

A teenager from Texas has taken quantum computing down a notch. In a paper posted online earlier this month, 18-year-old Ewin Tang proved that ordinary computers can solve an important computing problem with performance potentially comparable to that of a quantum computer. In its most practical form, the “recommendation problem” relates to how services like Amazon and Netflix determine which products you might like to try. Computer scientists had considered it to be one of the best examples of

Google Neutralizes Its Rivals… For Now

For over two decades, “Google it” has been the default way to find answers online. Now that dominance is being tested by a new wave of AI tools like OpenAI’s ChatGPT and upstarts such as Perplexity, which deliver conversational answers instead of a list of links. These disruptors are being cast as a mortal threat to Google Search, long the undisputed king of the internet.

Rare Bone-Eating Cancer Replaced Man’s Finger and Toe

A 55-year-old man’s swollen toes and fingers turned out to have a much stranger explanation than expected. In a recent case report, the man’s doctors detailed how some of his bones were “completely replaced” by metastatic tumors. Doctors in Australia described the case earlier this month in the New England Journal of Medicine. The man visited the hospital after weeks of having pain and swelling in one finger and one toe.
