The best air purifier for 2025

The air in our homes can be five times more polluted than outdoor air. Energy-efficient homes are designed to be tightly sealed, too, so they trap more pollutants inside. Cooking emissions, cleaning chemicals and fragrances all contribute to less-than-healthy air. Pets, smoke and off-gassing furniture do their part as well. If the air quality outside is good, the best thing to do is open up your windows for at least 15 minutes a day. But if wildfires, car pollution, or high pollen counts prevent

If you’re a student, these are the Apple products you should get for Back to School

School is about to start back up for a lot of people, and with how integral technology is to the classroom, having a good computer is always important. If you’re looking to pick up a new Apple device for school or college, I’ll be going over the best picks right here. Obviously, when it comes to Apple gear for school, you have to go over the most important Apple debate: iPad or Mac. I won’t be giving advice in that regard, though I will say that iPadOS 26 makes using an iPad as your all-in-one

AirPods Max in 2025? Same drawbacks, now ready for pros, and one killer feature

Jason Hiner/ZDNET Key takeaways The ability to switch quickly and seamlessly across an unlimited number of Apple devices is still the best feature of the AirPods Max. The low-latency upgrade in iOS 18.4 makes the AirPods Max a lot more viable for professional multimedia producers (and gamers) when using a wired connection. Comfort, battery life, and audio quality match high-end competitors from Sony, Bose, and others. Follow ZDNET: Add us as a preferred source on Google. Even with their im

A bubble that knows it's a bubble

The four words that precede every crash: “This time is different.” Except this time, the person warning about a bubble is Sam Altman, the CEO most responsible for creating it. When OpenAI’s chief executive warned last week that investors were “overexcited” about AI, markets reacted immediately. Nvidia fell 3.5%, Palantir dropped nearly 10%, and the selloff spread globally. The warning came amid a cascade of seemingly supporting data. That same week, MIT researchers published findings that 95%

YouTube made AI enhancements to videos without warning or permission

YouTube made AI enhancements to videos without telling users or asking permission. As AI quietly mediates our world, what happens to our shared connection with real life? Rick Beato's face just didn't look right. "I was like 'man, my hair looks strange', he says. "And the closer I looked it almost seemed like I was wearing makeup." Beato runs a YouTube channel with over five million subscribers, where he's made nearly 2,000 videos exploring the world of music. Something seemed off in one of his

Elon Musk says xAI has open sourced Grok 2.5

In Brief Elon Musk’s xAI has made an older version of its AI model Grok — specifically, the model weights used to shape Grok 2.5 — available on the open source platform Hugging Face. “The @xAI Grok 2.5 model, which was our best model last year, is now open source,” Musk wrote on X. He added that Grok 3 “will be made open source in about 6 months.” AI engineer Tim Kellogg described the Grok license as “custom with some anti-competitive terms.” Grok, which is prominently featured on X (which i

Materialized views are obviously useful

August 22, 2025 As programmers we spend a lot of time shuttling data back and forth between different systems and transforming it from one format to another. Sometimes it gets pretty miserable! Let’s say you’re making a fancy task tracking app. Tasks belong to projects, and on the projects page, you want to show how many tasks are in each project. Maybe you start with a little SQL that you call from your “get info about project” view model code: async function getTaskCountForProject ( project

Top Microsoft AI Boss Concerned AI Will Start to Demand Rights

In a blog post this week, Microsoft's head of AI Mustafa Suleyman responded to the drastic rise in mental health crises stemming from AI use, calling for caution "about what happens in the run up towards superintelligence." At the core of Suleyman's argument isn't the dystopian threat of AI gaining consciousness — an idea currently grounded more in fantasy than scientific evidence, according to many researchers — but the belief that it already is. "My central worry is that many people will sta

Experts Horrified by AI-Powered Toys for Children

Though talking toys are nothing new, a fresh crop of AI-enabled playthings have entered the scene, making the "Chatty Cathy" and "Teddy Ruxpin" dolls of yesteryear, which were merely reciting pre-programmed phrases, look positively paleontological. More than a decade after "My Friend Cayla" — a Bluetooth-enabled and Wi-Fi-connected doll that became "verboten in Deutschland" in 2017 for being a potential espionage device — Mattel and OpenAI's newly-announced partnership to "reimagine the future

Local Restaurant Exhausted as Google AI Keeps Telling Customers About Daily Specials That Don't Exist

If you're trying to find out what a restaurant has to offer, you might look up its menu, or go to its Facebook page. Hell, you could call and ask. But that's all démodé. Why not query an AI chatbot, a piece of software notorious for inventing facts out of the tokenized ether of the internet, and treat its answer like the word of God? Here's why: because you'd annoy the hell out of the restaurant. Just ask the beleaguered owners of the Montana eatery Stefanina's Wentzville, who are begging thei

Harvard Startup Says Its Smart Glasses Will Do "Vibe Thinking" for You

We live in an age where the tech industry's core pitch is for you to outsource your brain's cognitive functions, be it to an AI chatbot or an app. The idea has now reached a new zenith. A startup called Halo is releasing a pair of smart glasses that will record and transcribe all your conversations and use it to beam you AI-powered insights. It'll remember details you forgot and recall what someone told you they like, the startup says, arming you with facts it looks up on the fly and answering

Scientists Detect Precise Origin of Mysterious Signal From Deep Space

For almost two decades, astronomers have been trying in vain to explain extremely bright flashes of radio bursts emanating from deep space. Despite only lighting up for a tiny fraction of a second, these fast radio bursts (FRBs) have been known to release as much energy as the Sun puts out in an entire year. Now, in what's being called a "turning point," an international team of researchers has traced back the location of the origin of one of the brightest FRBs ever detected, allowing them to

You likely shouldn’t hold your breath for a new pair of AirPods Max: report

AirPods Max have had a bit of a disappointing history. After much anticipation, they finally released at the tail end of 2020. Some fans were disappointed with the high price tag and rather heavy aluminum and steel design, and have been looking forward to a revamp ever since. Despite being refreshed last year, it was merely just a USB-C port swap and new colors. The headphones still lack in features compared to Apple’s newer AirPods Pro 2, and that likely won’t be changing. Per Mark Gurman’s P

You can now download and tweak Grok 2.5 for yourself as it goes open source

Unhinged as Grok may be, it's now open source. xAI's CEO, Elon Musk, posted on X that the company made the older Grok 2.5 model available to the public and will do the same with the upcoming Grok 3. For now, anyone can download, run and even tweak Grok, whose source code was uploaded to the Hugging Face platform. However, there are restrictions to xAI's open-source license, which doesn't let people use Grok to train, create or improve other AI models. It's not the first time xAI has made its mo

US attack on renewables will lead to power crunch that spikes electricity prices

Witthaya Prasongsin | Moment | Getty Images President Donald Trump's attack on solar and wind projects threatens to raise energy prices for consumers and undermine a stretched electric grid that's already straining to meet rapidly growing demand, renewable energy executives warn. Trump has long said wind power turbines are unattractive and endanger birds, and that solar installations take up too much land. This week, he said his administration will not approve solar and wind projects, the lates

A German ISP changed their DNS to block my website

My website: Publishing Germany's secret internet blocklist In Germany, we have the Clearingstelle Urheberrecht im Internet (CUII) - literally 'Copyright Clearinghouse for the Internet', a private organization that decides what websites to block, corporate interests rewriting our free internet. No judges, no transparency, just a bunch of ISPs and major copyright holders deciding what your eyes can see. I decided to create a website, cuiiliste.de, to find blocked domains, as the CUII refuses to

South Korean Man Arrested in $50 Million Crypto Scam

A South Korean man was arrested in Bangkok, Thailand on Saturday, accused of laundering over $50 million worth of cryptocurrency into physical gold bars in the span of just three months. The man, identified by Thai authorities only as “Han,” was allegedly a key figure in a call-center fraud network that lured victims in with promises of 30-50% returns on investment. Authorities say the victims were paid off initially in small amounts to build trust before they started facing withdrawal limits l

Regulators Say Binance Must Tighten Money Laundering, Terrorism Rules

Beleaguered crypto company Binance must tighten up its compliance controls covering anti-money laundering and counter-terrorism and add an independent auditor if it wants to keep doing business in Australia, regulators said this week. The Australian Transaction Reports and Analysis Centre (AUSTRAC) is mandating the crypto giant put outside auditors in place within 28 days of its decision. The watchdog said that the new rules are intended to address “serious concerns” it has about its oversight

5 Galaxy AI features that actually make my life easier on a Samsung phone

Prakhar Khanna / Android Authority I’ve been using the Galaxy Z Fold 7 since its launch and recently switched to the Flip 7. Apart from the Good Lock features and One UI 8 customizations, there’s another Samsung feature that has stood out for me in recent times. To my surprise, I have grown used to certain Galaxy AI features. I am not heavily reliant on them, but they do make my life easier… sometimes. In fact, I miss parts of Galaxy AI when I put my SIM in other phones for testing. From regul
