New Details Emerge About Ancient Inca Counting Technology

The Inca were a pre-Columbian civilization whose empire sprawled along South America’s Pacific Coast from the 15th to the 16th century CE. Like other Andean peoples, they used khipus (also known as quipus), an intricate cord and knot system used to record information. According to Spanish colonial-era sources, only male Inca elites could make khipus. A new study, however, challenges this widespread notion. In a paper published today in Science Advances, an international team of researchers inve

Norton VPN review: A VPN that fails to meet Norton's standards

One thing I need to make clear right from the start: this is a review of Norton VPN (formerly Norton Secure VPN, and briefly Norton Ultra VPN) as a standalone app, not of the VPN feature in the Norton 360 package. They're similar, but Norton VPN has a few more features, including the ability to choose cities as server locations in countries with more than one option. I'll state my opinion up front. Norton VPN isn't a bad service, but it's not good enough to get ahead of its direct competitors.

‘Are You Surprised?’: Trump Shrugs Off New Suspected Hack of Documents by Russia

President Donald Trump was asked on Wednesday about the recent hack of a computer system that holds highly sensitive federal court documents. Russia is suspected to be behind the attack, as the New York Times first reported on Tuesday. But Trump doesn’t seem to think it was a big deal, even as the president prepares to meet with Russia’s President Vladimir Putin. Trump was asked by a reporter if he would bring up the hack when he meets Putin in Alaska on Friday. “I guess I could,” Trump replied

Best Organic Mattresses (2025): Birch, Avocado, Naturepedic, More

After years of testing, the Avocado Green hybrid mattress remains one of the best organic mattresses I've slept on. It's the only mattress my wife and I can agree on. She likes a soft mattress, and I prefer a firm one. This model somehow manages to be both without being too much of either. It's also good for combination sleepers like myself, who spend time in just about every position in the course of a night. After nearly three years of sleeping on this Avocado, it's proven its durability—there

CoreWeave stock slumps 18% on wider-than-expected loss ahead of lock-up expiration

CoreWeave 's stock dropped 18% after the renter of artificial intelligence data centers reported a bigger-than-expected loss. In its second quarterly financial results as a public company, CoreWeave reported an adjusted loss of 27 cents per share, compared to a loss of 21 cents per share expected by analysts polled by LSEG. CoreWeave's results came as the lock-up period following its initial public offering is set to expire Thursday evening and potentially add volatility to shares. The term re

This website is for humans

8 August 2025 Walking past a bus stop yesterday I saw an advert for Google’s AI search. The person in the ad had pointed their phone’s camera at a bowl of ramen, and the AI result explained how to reproduce it at home. How does it know? Because it’s trained on all the ramen recipes that multiple recipe authors spent hours, weeks, years perfecting. Generative AI is a blender chewing up other people’s hard work, outputting a sad mush that kind of resembles what you’re looking for, but without an

Scientists Unveil Wild New Way to Explore the Edge of Space

Scientists often refer to the mesosphere as the “ignorosphere”—a region that’s too high for planes or weather balloons to explore, yet too low for satellites to probe. Despite our technological advances, we’ve yet to find a decent way to monitor this large stretch of air, which lies about 37 miles (60 kilometers) above the surface. But engineers are inching towards a solution—one inspired by a toy-like invention from the 19th century. A Nature paper published today presents a proof-of-concept f

10 Best Computer Monitors (2025): Budget, OLED, 4K

Once you've decided on a size, there are a number of other important aspects of your next monitor to consider. Some of these factors may matter more for certain uses—for example, gamers generally care more about higher frame rates than office workers do—but they're all handy to know going in. Resolution: The bigger the monitor, the more it will benefit from higher resolutions. That will allow you to have app windows that take up less space but are still legible. Most monitors today are typicall

Your Windows PC has a secretly useful backup tool - here's how to access it

Lance Whitney / Elyse Betters Picaro / ZDNET ZDNET's key takeaways Windows has a hidden backup tool in Windows 10 and 11. It can save files to discs, drives, or network locations. Deprecated by Microsoft, so expect occasional errors. Regularly backing up your files is always a good idea, just in case any important or irreplaceable ones go missing. For that, you can turn to a variety of programs. But Windows itself has a built-in backup tool that's simple and flexible. The catch is that you

Best Side-Sleeper Mattress 2025: Picked by a Sleep Science Coach

If you are looking for the best side-sleeper mattresses, welcome. You’re in good company, as many of the WIRED Reviews team are also side sleepers. So are most Americans. The numbers vary across studies and depend on how rigidly you define “side sleeper,” but between half and three-quarters of people sleep on their side for at least part of the night. If you're a side sleeper, you know how crucial it is that your bed keeps your back aligned while the hips and shoulders get some cushioning. Othe

StubHub is once again working on its IPO that could raise $1B

In Brief StubHub is giving a strong indication that its IPO is back on again. It filed a public S-1 in late March, then paused in April after the Trump administration’s tariffs spooked Wall Street. On Monday, it filed an updated S-1 that now includes Q1 2025 results. IPO experts Renaissance Capital estimated in March that the IPO could raise $1 billion, and says this fresh S-1 could mean a debut next month. StubHub declined to comment on its IPO plans, citing its quiet period. In 2024, it g

Now That Google Is Trash, It Will Let You Pick Your Own News Sources

Google seems to have destroyed the quality of its search results (and its reputation) by loading its feed with sponsored results, pages boosted by SEO black magic, and AI-generated slop. So it’s putting the control back in your hands, for better or worse. The company announced today via blog post a new feature called Preferred Sources that will let users select their own favorite news outlets to appear at the top of their personalized search feed. According to Google, the feature has already st

Is your iPhone alarm not going off? 6 potential fixes that worked for me

Elyse Betters Picaro / ZDNET I started noticing something very annoying at the beginning of the year: I'd set my iPhone alarm for 7 a.m., only to sleep right through it. At first I assumed it was my mistake -- maybe I'd accidentally left the ringer volume all the way down. But after double-checking that, even switching off vibrate and cranking the volume all the way up overnight, the problem persisted. Somewhere between frustration and desperation, I installed a third-party alarm app to try an

AI companion apps on track to pull in $120M in 2025

Demand for AI “companion” applications outside of bigger names, like ChatGPT and Grok, is growing. Of the 337 active and revenue-generating AI companion apps available worldwide, 128 were released in 2025 so far, according to new data provided to TechCrunch by app intelligence firm Appfigures. This subsection of the AI market on mobile has now generated $82 million during the first half of the year and is on track to pull in over $120 million by year-end, the firm’s analysis indicates. Unlike g

Show HN: Building a web search engine from scratch with 3B neural embeddings

Building a web search engine from scratch in two months with 3 billion neural embeddings A while back, I decided to undertake a project to challenge myself: build a web search engine from scratch. Aside from the fun deep dive opportunity, there were two motivators: Search engines seemed to be getting worse, with more SEO spam and less relevant quality content. Transformer-based text embedding models were taking off and showing amazing natural comprehension of language. A simple question I ha

Study finds your smartwatch might be way off on one key health stat

Kris Carlon / Android Authority TL;DR Study finds smartwatch stress scores often don’t match how you actually feel. Researchers tracked 800 Garmin users for three months and saw “basically zero” correlation for stress. Sleep tracking was more accurate, but better at logging hours slept than rest quality. They’re meant to be your health sidekick, you might suspect that there’s only so much that a wearable can tell you about your mental state from taking a pulse reading. If this wasn’t already

Google lets you pick preferred sources when you search

Google is officially rolling out Preferred Sources, which lets you curate search results. The feature allows you to pick specific or "preferred" sources, like a certain blog or news outlet, and see them more prominently when you use Google Search. Google started testing it in June and it should be available in the coming days to English language users in the US and India. Preferred Sources seems pretty simple to use. You go to Google, search for a topic and then click on the preferred sources o

Why AI Shouldn’t Replace Historians Anytime Soon

Microsoft recently released a study about the types of jobs most likely to be augmented by AI in the future. It led many people to assume those are the jobs that will soon be replaced by machines, and since “historian” ranked second highest on the list, it raised more than a few eyebrows among historians on social media. But after I tested generative AI tools with some historical facts, it seems like historians shouldn’t worry too much about the robots taking over just yet. At the very least, th

Women's health tracking features take center stage with this Oura update
