Dictionary.com “devastated” paid users by abruptly deleting saved words lists

Logophiles are "devastated" after Dictionary.com deleted their logs of favorited words that they carefully crafted for years. The company deleted all accounts, as well as the only ways to use Dictionary.com without seeing ads —even if you previously paid for an ad-free experience. Dictionary.com offers a free dictionary through its website and free Android and iOS apps. It used to offer paid-for mobile apps, called Dictionary.com Pro, that let users set up accounts, use the app without ads, and

ChatGPT can now browse and perform web-based tasks for you

In a quick live stream today, OpenAI announced ChatGPT agent, which improves on its promising, but limited Operator feature announced a few months ago. Here’s how it works Operator meets Deep Research What OpenAI did was combine Operator, which already had agentic browsing capabilities, and Deep Research, which can quickly consume, understand, and infer on website content. The result is an agent that gets spun up on a virtual machine when you assign it a task, and then it just… goes. It can

ChatGPT’s new AI agent can browse the web and create PowerPoint slideshows

On Thursday, OpenAI launched ChatGPT Agent, a new feature that lets the company's AI assistant complete multi-step tasks by controlling its own web browser. The update merges capabilities from OpenAI's earlier Operator tool and the Deep Research feature, allowing ChatGPT to navigate websites, run code, and create documents while users maintain control over the process. The feature marks OpenAI's latest entry into what the tech industry calls "agentic AI"—systems that can take autonomous multi-s

Android’s Linux Terminal arrives on the Galaxy Z Flip 7, but Z Fold 7 users are left out

Mishaal Rahman / Android Authority TL;DR Samsung’s new Galaxy Z Flip 7 is the first non-Pixel phone to support Google’s Linux Terminal app, but the feature is curiously missing from the Z Fold 7. The app requires a non-protected virtual machine, which the Z Flip 7’s Exynos chip supports but the Z Fold 7’s Snapdragon chip currently does not. The Terminal app runs a Linux VM and is part of Android 16, but it probably won’t be available on many other devices. Back in March, Google rolled out a

OpenAI Unleashes ChatGPT Agent to Be Your Personal Assistant

OpenAI has launched ChatGPT Agent for Pro, Plus and Team users -- an AI-powered personal assistant that connects to your various services online to help complete tasks custom to you, the company said in a livestream on Thursday. Using the power of OpenAI's "reasoning" o3 model, which has deep research capabilities, along with Operator, ChatGPT Agent can go step-by-step from one task to the other to put together complex reports. ChatGPT Agent can visualize what it's doing via a virtual computer

NASA's Jet Propulsion Laboratory Reportedly Holding "Going Out of Business Sale" for Satellites

NASA's Jet Propulsion Laboratory Reportedly Holding "Going Out of Business Sale" for Satellites NASA scientists are furious. Fire Sale NASA's Jet Propulsion Lab is reportedly holding a "going out of business sale" for its satellites, NASA Watch reports. The list of for-sale assets includes several Earth-monitoring satellites that were once tasked with studying the environment, helping with hurricane prediction efforts, and measuring the effects of climate change. Most launched over the last

Fighting AI with AI, finance firms prevented $5 million in fraud - but at what cost?

d3sign/Getty Imageds When most people think of AI, the first thing that probably comes to mind isn't superintelligence or the promise of agents to boost productivity, but scams. There've always been fraudsters among us, that small percentage of the population who'll use any means available to swindle others out of their money. The proliferation of advanced and easily accessible generative AI tools in recent years has made such nefarious activity exponentially easier. Also: Meet ChatGPT agent,

Synths hunt down deadly monsters in latest Alien: Earth trailer

The premiere of Alien: Earth is just weeks away, and FX/Hulu dropped one last trailer to pique our interest, along with a much more detailed synopsis. It's meditative and existential in tone, with a haunting tune playing over footage of mysterious alien craft, dead bodies, blood-spattered humans fleeing through futuristic corridors, and, of course, a spooky silhouette of a xenomorph in the distance. As previously reported, the eight-episode series is set in 2120, two years before the events of

ChatGPT isn't just for chatting anymore - now it will do your work for you

Elyse Betters Picaro / ZDNET Not too long ago, I wrote that AI agents were the future of AI: tools that could carry out tasks for you, like ordering groceries or booking meetings. OpenAI's latest launch makes that reality appear a bit closer. Also: AI agents will change work and society in internet-sized ways, says AWS VP On Thursday, during a live stream, OpenAI launched a ChatGPT agent, which the company claims can handle complex tasks for you from start to finish. Some examples OpenAI prov

OpenAI’s New ChatGPT Agent Tries to Do It All

Isa Fulford, the research lead for OpenAI’s new ChatGPT agent, needed to order a bunch of cupcakes, so she asked the AI tool to do it for her. “I was very specific about what I wanted, and it was a lot of cupcakes,” she says. “That one took almost an hour—but it was easier than me doing it myself, because I didn't want to do it.” OpenAI has launched a new agent for ChatGPT that uses a virtual browser to complete tasks and can generate downloadable files, specifically PowerPoint presentations an

OpenAI launches a general purpose agent in ChatGPT

OpenAI is launching a new general purpose AI agent in ChatGPT, which the company says can complete a wide variety of computer-based tasks on behalf of users. OpenAI says the agent can automatically navigate a user’s calendar, generate editable presentations and slideshows, and run code. The tool, called ChatGPT agent, combines several capabilities from OpenAI’s previous agentic tools, including Operator’s ability to click around on websites, as well as Deep Research’s ability to synthesize info

Molecule produced by gut bacteria causes atherosclerosis

A team of Spanish scientists made a striking announcement 15 years ago: they were seeking thousands of volunteers among the employees of Banco Santander in Madrid: researchers wanted to study them in depth for decades, in order to understand the onset of cardiovascular disease in healthy people. The results are even more surprising. Researchers have discovered that gut bacteria produce a molecule that not only induces but also causes atherosclerosis, the accumulation of fat and cholesterol in th

Elon Musk Wants to Turn AI Into a Cosmic Religion

It is one of his more abstract philosophical riffs. Elon Musk has once again linked the fate of humanity to the trajectory of artificial intelligence. And this time, he says the key to AI safety might be babies and rockets. The CEO of Tesla’s latest pronouncement cuts through the typical discussions of AI efficiency and profit models, positing a far grander ambition for advanced intelligence. The CEO of Tesla and founder of SpaceX and xAI asserted that “AI is a de facto neurotransmitter tonnage

8 Healthy ‘Three-Parent’ Babies Born in UK Using Pioneering IVF Technique

So-called “three-parent” babies are thriving in the U.K. New clinical trial research shows that several healthy children in the country have been born with the DNA of three people. Doctors at Newcastle University led the study, which involved around two dozen women with a high risk of passing down harmful mutations of their mitochondria to their children. So far, eight kids have been born using an in vitro fertilization (IVF) technique that replaces a mother’s damaged mitochondrial DNA with tha

Boeing’s Starliner Won’t Get to Fly This Year, but the Wonky Spacecraft Is Far From Dead

It’s been more than a year since Starliner’s failed test flight left a crew stranded in space, and Boeing’s spacecraft still isn’t ready to fly. In a recent update, NASA officials said they are working toward launching a mission aboard Starliner in 2026, and there probably won’t be any astronauts involved. During a press briefing last week, Steve Stich, NASA’s commercial crew program manager, told reporters that Boeing is making several changes to its Starliner spacecraft to keep its thrusters

I love anti-reflective displays, but an iPhone one is no big deal

A report yesterday suggested that the two iPhone 17 Pro models could get an anti-reflective display, after Apple’s suppliers managed to overcome production difficulties. I do love anti-reflective displays, and still have very fond memories of my all-time favorite Apple one from way back in 2004, but an iPhone one would have only moderate appeal to me … There was a time when all screens were matte. Then along came glossy screens, Apple and the rest of the tech industry fell in love with them, a

Boulevard raises $80M to power self-care boom driven by Botox and GLP-1 surge

The beauty industry has seen an explosion of offerings recently. Customers can now access treatments far beyond basic hair and nail care, from wrinkle-smoothing Botox and fillers to permanent laser hair removal and even weight management through GLP-1 medications. Riding this wave of industry growth is Boulevard, a provider of scheduling and payment software for the self-care sector. The nine-year-old Boulevard just raised $80 million in Series D funding, valuing the business at nearly $800 mi

Hackers are trying to steal passwords and sensitive data from users of Signal clone

Hackers are targeting a previously reported bug in the Signal clone app TeleMessage in an effort to steal users’ private data, according to security researchers and a U.S. government agency. TeleMessage, which earlier this year was revealed to be used by high-ranking officials in the Trump administration, already experienced at least one data breach in May. The company markets modified versions of Signal, WhatsApp, and Telegram for corporations and government agencies that need to archive chats

Crypto theft is booming as criminals increasingly turn to physical attacks

The value of cryptocurrencies stolen by criminals surged in the first six months of 2025 after a high-profile hack and a wave of physical attacks targeting crypto holders and their relatives. So far this year, $2.17 billion has been stolen from crypto services — already eclipsing the $1.87 billion of funds stolen from platforms in 2024 — and this is expected to reach $4 billion by the end of 2025, according to a report published Thursday by blockchain analysis firm Chainalysis. Overall, the co

Voting age to be lowered to 16 in UK by next general election

The voting age will be lowered to 16 across the UK by the next general election in a major change of the democratic system. The government said it was a reform to bring in more fairness for 16- and 17-year-olds, many of whom already work and are able to serve in the military. It brings the whole of the UK voting age to 16. Scotland and Wales have already made the change for Holyrood and Senedd elections, as well as local council elections. In a sweeping package of changes, ministers will also

What Makes Cheap Earbuds a Real Value (or Not)? I Dug In to Find Out

A few months ago, Final Audio, a boutique Japanese brand, sent me its new, relatively low-priced ZE3000 SV noise-canceling earbuds to test. I was curious: Would this be a hidden gem among the dozens, even hundreds, of budget headphone options out there? Even as a full-time reviewer of these products, I can't keep up with all of them. So I did what I always do. I charged them up, then swapped out the default medium-size tips for the largest set of included ear tips and hoped I'd get a tight seal

An Engineer’s Diary Reveals the Human Cost of Building OpenAI’s Next Big Thing

Behind the seemingly magical abilities of OpenAI’s technology lies a story of intense human effort and immense personal sacrifice. In a candid reflection posted on July 15, former top engineer Calvin French-Owen peeled back the curtain on the company’s high stakes culture. He detailed a product launch that was “unquestionably one of the highlights of my career” but also the “hardest I’ve worked in nearly a decade.” French-Owen is a seasoned tech leader who cofounded the successful data company

Crypto accumulator DeFi Development to expand globally by franchising its Solana treasury model

DeFi Development , a company vying to be the MicroStrategy of Solana, is expanding internationally through a franchise model. The company plans to partner with others looking to operate their own Solana treasuries with DeFi's support. In return, DeFi Development will retain an equity stake in each regional vehicle. The initiative will be branded DFDV Treasury Accelerator. "Most crypto treasury vehicles today are following the MicroStrategy model. What excites us about DFDV is that they're not

I tried going self-hosted but Google Drive is just too convenient

Karandeep Singh / Android Authority A network-attached storage (NAS) is supposed to give you an alternative to cloud storage — one that’s safer, more private, and free from monthly subscriptions. A lot of home users may still consider those strange black boxes nerd territory, but Synology wanted to make the transition easier for Google Drive users. Its own alternative, deceptively named Synology Drive, is made to offer Google Drive-like storage. While it sounds compelling in theory and is genu
