Time travel? Or, just clever technology

SyncDNA • September 18, 2025 "audio" "collaboration" "explained" It sounds too good to be true, doesn't it? We promise perfect synchronization, frame and sample accuracy, low-latency realtime conferencing, and remote recording and review, but how on earth is that possible? We have, multiple times, recorded "jams" between musicians in Canada and Germany; doesn't that break the laws of physics? Well, no. The trick is, we don't do all of those things at the same time, and we use very different a

Android’s answer to Apple’s Handoff is coming, and here’s how it’ll work

Mishaal Rahman / Android Authority One area where iOS beats Android is its deep integration with MacBooks, which is to be expected since Apple controls both ecosystems. While tools exist to connect your Android phone to a Windows PC, these solutions often fall short of Apple’s integrations. This gap exists because Android and Windows are developed by different companies with competing interests, which complicates the creation of native, deeply integrated features. For example, Apple’s Handoff

The iPhone Air 2 Is Probably Not Getting an Ultrawide Camera

The iPhone Air has been available for a week as of the publication of this post, and the top complaint I keep hearing about the super-skinny phone is not even that its battery may not last long enough or that it may scratch easily, but that there’s only one back camera. Everyone seems willing to wait for Apple to add an ultrawide lens to next year’s presumably named iPhone Air 2. I wouldn’t bet on that. Get the iPhone Air now, or buy an iPhone 17 or iPhone 17 Pro if you really need an ultrawide

Don’t like your group chat icon? Google Messages might soon let you remove it

Adamya Sharma / Android Authority TL;DR An Android Authority teardown of the latest Google Messages beta has revealed a change to group chat icons in testing. We managed to activate the option to remove a group chat icon and restore the default four-avatar grid. Right now, you can only change the group chat icon; you can’t remove it. One of the little quirks of a Google Messages group chat is that once you set a picture as the group icon, you can’t go back. You can swap it for another photo,

Don’t Count on the iPhone Air 2 Getting an Ultrawide Camera

PlayStation State of Play September 2025: all the news and trailers

Just ahead of the launch of Ghost of Yōtei on the PS5 next week, Sony is holding its latest State of Play showcase to detail what’s coming next for the platform. One thing that we know will make an appearance for sure is Saros, the latest dark sci-fi game from Returnal studio Housemarque. Aside from that, though, it’s not really clear what to expect from the event. Sony says it will span around 35 minutes and include “new looks at anticipated third-party and indie titles, plus updates from some

Save $50 on Our Favorite Budget Graphics Card

If you're building a new gaming PC, I've got a sweet deal for you on a graphics card. The PNY Nvidia GeForce RTX 5060 Ti OC (7/10, WIRED Review) is currently marked down to just $379 at Walmart. While prices have been in flux since launch, this is anywhere from $50 to $100 off the usual price, a discount that makes it a much more appealing purchase for gaming at 1080p. This is the most modest entry from Nvidia's 50 Series that I think is worth your time, but that doesn't mean that you'll be dis

Objects in your Android Auto display are not closer than they appear — it’s just glitched

TL;DR Some Android Auto users report the interface suddenly appearing magnified. The bug affects apps like Google Maps and Spotify, both wired and wireless. It’s not yet clear how many users are affected, or whether the issue lies with the phone model. Android Auto problems occur now and then, but the latest one is pretty odd. A few drivers say the Android Auto interface has suddenly started looking magnified, with apps like Google Maps and Spotify blown up far beyond normal. The reports we

iFixit zooms in on reports of an iPhone 17 Pro scratch problem

Apple’s new, anodized aluminum iPhone 17 Pro phones have drawn attention for reportedly being easy to scratch around the camera “plateau,” and iFixit has investigated the issue in microscopic detail in its teardown video for the phones. Here are some pictures showing just what those scratches look like under a digital microscope: Previous Next 1 / 4 Image: iFixit iFixit talked to David Niebuhr, an engineer and professor of mechanical engineering, who has an explanation for why scratches

YouTube may reinstate channels banned for spreading covid and election misinformation

Channels once banned by YouTube for spreading false information regarding the COVID-19 pandemic or the 2020 election may soon have the opportunity to get their channels back, in a decision transparently courting "conservative voices." Alphabet, the parent company of Google and YouTube, has sent a letter via counsel to the House Judiciary Committee in which it alleges the company was pressured by the Biden administration to take down misinformation on YouTube related to the COVID-19 pandemic tha

WhatsApp adds message translation to iPhone and Android apps

WhatsApp has started rolling out a new translation feature that enables Android and iPhone users to translate messages in chats, groups, and channel updates. While iOS users can only use it to translate manually after tapping 'Translate,' Android users will also be able to enable automatic translation, allowing all messages in a chat thread to be translated without having to tap each one individually. "We're rolling out message translations to Android and iPhone users gradually from today, in

Trump and RFK Jr. Blame Tylenol For Autism in New Report, but Experts Push Back

President Donald Trump and U.S. Health and Human Services Secretary Robert F. Kennedy Jr. have officially found scapegoats to blame for rising rates of reported autism cases. In a report published today by HHS, the government has linked the use of acetaminophen (better known as Tylenol) during pregnancy to the neurodevelopmental condition. Trump made the announcement at a news conference Tuesday afternoon, though the Wall Street Journal was the first to break the news on the expected findings e

How Isaac Newton discovered the binomial power series (2022)

Isaac Newton was not known for his generosity of spirit, and his disdain for his rivals was legendary. But in one letter to his competitor Gottfried Leibniz, now known as the Epistola Posterior, Newton comes off as nostalgic and almost friendly. In it, he tells a story from his student days, when he was just beginning to learn mathematics. He recounts how he made a major discovery equating areas under curves with infinite sums by a process of guessing and checking. His reasoning in the letter is

Download responsibly

This month we’ve ramped up the infrastructure behind the download server, and downloads should now be available earlier and faster. There’s also a small technical change in that requests for a “…latest” file will now be answered with a HTTP redirect to the specific latest version (see previous blog post). I would like to use this opportunity to appeal to users of the download server to “download responsibly”. We want to continue offering this service as powerful and as convenient as possible

The touchscreen MacBook rumors are never ending

Analyst Ming-Chi Kuo took to X on Wednesday to claim that a MacBook Pro with an OLED touchscreen was expected to enter mass production by late 2026. Today Bloomberg’s Mark Gurman is following up to remind us that he was reporting on a touchscreen MacBook Pro way back in 2023. He confirmed Kuo’s timeline was correct. Since Gurman’s original story, the launch date has been pushed back from late 2025, to late 2026 or early 2027. Apple has traditionally been resistant to the idea of merging the iPa

One of the Year's Biggest Horror Movies Is Now Streaming on Netflix

28 Years Later is the long-awaited third release in Danny Boyle's iconic zombie franchise. The movie premiered in theaters this year and, just in time for spooky season, the hit horror movie is now streaming. It all started more than two decades ago when Boyle partnered with writer-director Alex Garland to bring 28 Days Later to the big screen. It was followed by the sequel, 28 Weeks Later, in 2007, which Boyle executive-produced. Instead of your typical undead fare, the franchise features a ne

Google could make Android 17 work better with life-saving medical devices

Rita El Khoury / Android Authority Hundreds of millions of people live with diabetes or other chronic conditions that require continuous monitoring. Fortunately, modern medical devices make it significantly easier for people to track their glucose levels, blood pressure, and other key vitals. Some even connect directly with smartphones, sending crucial data and alerts via Bluetooth to the mobile devices we carry every day. Despite the importance of these medical devices in many people’s lives,

Show HN: Math2Tex – Convert handwritten math and complex notes to LaTeX text

Hi HN, I’m the creator of Math2Tex. I was a PhD student, I spend a huge amount of my time working with LaTeX, especially when dealing with lecture notes, academic papers, and homework.

The New Meta Ray-Bans Might Be Your Next Disneyland Tour Guide

Walt Disney Imagineering is in the early stages of prototyping a new augmented reality experience at its theme parks. This week, the team released a video showing Meta's Ray-Ban smart glasses used as a personal virtual assistant inside Disneyland. Meta is just one of the companies Disney Imagineering R&D is working with on AR. The Ray-Ban smart glasses allow Disney guests to ask questions out loud and receive real-time responses with information about rides, attractions, merchandise, food and d

I Tested AirPods Live Translation With My Family. Here's What I Learned

I couldn't ask for better timing. My Spanish-speaking mother-in-law was coming to visit the day Apple released live language translation features on AirPods. It works on the new AirPods Pro 3, which hits stores Friday, along with last year's AirPods Pro 2 and AirPods 4 -- and the user also needs to have it paired to an iPhone running the latest iOS 26 software with Apple Intelligence. My mother-in-law is bilingual and speaks English perfectly, but Spanish is her preferred language. She'll ofte

I tried Pixel 10’s Voice Translate on real calls: Here’s the good and the bad

Adamya Sharma / Android Authority Google is constantly pushing the boundaries of AI in its Phone app, and the new Voice Translate feature on the Pixel 10 series is one of its most ambitious attempts yet. The idea is to break down language barriers in real time and make phone conversations smoother when you and the person on the other end speak completely different languages. What’s even more fascinating is that Voice Translate attempts to mimic the voice of the speakers in order to make convers

'28 Years Later' Is Coming to Netflix. Here's When to Watch

28 Years Later, the third release in Danny Boyle's iconic zombie franchise, premiered in theaters earlier this year. Just in time for spooky season, the hit horror movie is coming to streaming -- and it's happening this week. Over two decades ago, Boyle partnered with Alex Garland to bring 28 Days Later to life. It was followed by the sequel, 28 Weeks Later, in 2007. Instead of your typical undead fare, the franchise features a new type of threat: Running zombies infected with a biological weap

This Giant Subterranean Neutrino Detector Is Taking On the Mysteries of Physics

Located 700 meters underground near the city of Jiangmen in southern China, a giant sphere—35 meters in diameter and filled with more than 20,000 tons of liquid—has just started a mission that will last for decades. This is Juno, the Jiangmen Underground Neutrino Observatory, a new, large-scale experiment studying some of the most mysterious and elusive particles known to science. Neutrinos are the most abundant particles in the universe with mass. They are fundamental particles, meaning they d

Robert Redford has died

From time to time, people with similar political priorities encouraged him to run for office. He brushed such chatter aside, having become disillusioned with government in the late 1970s, when he was elected commissioner of the Provo Canyon sewer district. (He had sought the office in an effort to protect the Provo Canyon area near his home from development and pollution. But he quickly encountered bureaucracy, which reinforced his belief that independent activism and storytelling through film w
