Cara – High Precision Robot Dog Using Rope

Finding the Exact 8:1 Gear Ratio The starting point of this project was figuring out how to achieve an exact 8:1 gear ratio with the capstan drives. In my capstan drive video, I designed all the drives to have an 8:1 gear ratio—but when measured, none of them actually did. The commenters on that video pretty accurately diagnosed my mistake. I had made the outer diameter of the big drum 8 times larger than the outer diameter of the small drum, but this doesn't account for the diameter of the rop

UK targets Apple’s and Google’s mobile platforms for regulation

In Brief The U.K.’s Competition and Markets Authority (CMA) announced on Wednesday a proposal that would give Apple’s and Google’s mobile platforms “strategic market status” — a designation that allows the regulator to create rules that could change how their app stores operate and how their mobile software works. The move is designed to create a more open, competitive environment for the app economy and user choice. However, Apple and Google have pushed back at the proposals, with Apple sayin

Open source X rival Mastodon begins raising funds with new in-app donation feature

Open source X and Threads competitor Mastodon will begin experimenting with a new way to raise funds: in-app donations. The organization on Wednesday announced it’s launching a campaign that introduces banners inside its Android and iOS apps, prompting users to make a monetary donation. Initially, the feature will be shown only to those on the Mastodon servers the nonprofit itself operates, Mastodon.social and Mastodon.online. These banners will be easy to dismiss, Mastodon says, and will only

Finally, a tablet that can easily replace my iPad and Kindle (and doesn't break the bank)

TCL Nxtpaper 11 Plus ZDNET's key takeaways The TCL Nxtpaper 11 Plus is available for $249.

Meta researchers are developing a gesture-controlled wristband that can interact with a computer

Meta researchers are developing a wristband that lets people control a computer using hand gestures. This includes moving a cursor, opening apps, and sending messages by writing in the air as if using a pencil. Meta’s wristband employs a technique called surface electromyography (sEMG), which detects electrical signals generated by muscle activity to interpret user movements, as explained in a research paper published in the journal Nature. These signals can sense a person’s intended actions, e

Tech Industry Figures Suddenly Very Concerned That AI Use Is Leading to Psychotic Episodes

For months, we and our colleagues elsewhere in the tech media have been reporting on what experts are now calling "ChatGPT psychosis": when AI users fall down alarming mental health rabbit holes in which a chatbot encourages wild delusions about conspiracies, mystical entities, or crackpot new scientific theories. The resulting breakdowns have led users to homelessness, involuntary commitment to psychiatric care facilities, and even violent death and suicide. Until recently, the tech industry

Physicists Blow Up Gold With Giant Lasers, Accidentally Disprove Renowned Physics Model

Scientists equipped with giant lasers have blown up gold at SLAC National Accelerator Laboratory, heating it to 14 times its boiling point. For a chilling second, they thought they broke physics, but they fortunately did no such thing. That said, they broke something else: a decades-long model in physical chemistry having to do with the fundamental properties of matter. In an experiment presented today in Nature, researchers, for the first time ever, demonstrated a way to directly measure the t

Wow, James Gunn Really Hated Those ‘Peacemaker’ Cameos in the Old DCU

The second season of Peacemaker, starring WWE champion and actor John Cena, is just around the corner. With it comes a lot of questions about how the anti-hero will fit into both the old and new DC canon, given his limbo status, which has even led DC Studios head James Gunn to voice his frustration. Speaking with Den of Geek ahead of San Diego Comic-Con, Gunn reiterated that the second season of Peacemaker will address all the continuity confusion questions related to DC’s past and present. “T

Forget Samsung Z Fold 7: Why this Galaxy model is on my watchlist going into next year

Jason Howell/ZDNET Samsung's new Galaxy Z Fold 7 is an impressive book-style foldable that tackles many of the long-standing quibbles plaguing the Fold series for years. I spent a weekend with the device, and was floored by how much its reduced weight and thickness made it feel like a standard candy bar phone when folded. CNET survey: 64% of people say 'no thanks' to foldable smartphones The cover screen is wider and more usable, the interior display is larger at eight inches, and the new 200

Yes, you can disable Gemini permissions on your Android phone — here’s how

Joe Maring / Android Authority Any burgeoning new technology is almost always met with criticisms — some justified, and others not so much. Lately, Google’s Gemini has been the focus of such critiques. Last month, Gemini was under the microscope for an email that suggested it would soon gain a worrying level of access to your other Android apps. However, Google quickly reassured users that they were still in control of their data. Now, the Gemini Android app has come under fire for how it acce

Japan Just Broke the Internet Speed Record. How Fast Is It? You Could Download all of Netflix in Under a Minute

What if you could download Netflix’s entire library in under a second? How about every English language page on Wikipedia (including all revisions) five times over? That’s the dream scientists at Japan’s National Institute of Information and Communications Technology have made a reality, achieving a world record in data transmission speed of 1.02 Petabits per second over 1,123 miles -- roughly the distance between Miami and Cleveland. To put that in perspective, we usually measure internet spe

Playful Airline Safety Videos Could Be Making Passengers Less Safe

When you board a plane, chances are you want to stick your noise-canceling earphones in as soon as possible and pass out before the toddler in the row behind you starts screaming. Plus, if you’re a frequent traveler, you probably know the in-flight safety video by heart. Or do you? A survey published last month in the Journal of Travel Research reveals that not only did most participants fail an airline safety quiz immediately after watching the in-flight safety video, but that viewers of video

It Looks Like the Tesla Model Y Refresh Has Bombed

Despite Elon Musk stepping away from his DOGE activities, Tesla’s sales have continued to slide. No doubt Musk hoped that the release earlier this year of the refreshed Model Y would help reverse these fortunes; however, describing the six-year-old midsize crossover EV as “new” appears not to have attracted as many buyers as Tesla anticipated. Model Y is crucial for Musk; it accounts for roughly two-thirds of Tesla's global sales (though this fluctuates). Last year, however, according to JATO D

This waterproof speaker floats with you in the pool, but that isn't its best feature

Soundcore Boom 3i Waterproof Bluetooth Speaker ZDNET's key takeaways The Soundcore Boom 3i is available now on Amazon for $110. With some EQ tweaking, it produces better sound than you'd think for a waterproof speaker. The Boom 3i does float, but playing music while half-submerged doesn't sound the best. $129.99 at Amazon Vacation time is in full swing, which means you're probably heading to the great outdoors.

A media company demanded a license fee for an Open Graph image I used

22nd July 2025 I displayed an open graph image and had to pay how much?! A media company demanded a license fee for an Open Graph image used on my twitter archive. I gave in and paid it, but what does that mean for open graph images and copyright? In April 2025, I received an email from an image licensing company (hereby "licensor") regarding an image used on my twitter archive. That image was owned by them, but used as the Open Graph image for a news article. They demanded I purchase a licen

People Click Links Less Frequently When AI Summary Appears on Google Search, Study Shows

Google's AI Overviews, which are AI-generated summaries that appear at the top of search results for certain types of queries, are less likely to lead to clicks for sites, according to a report from Pew Research on Tuesday. The study is based on data from 900 US adults who shared their browsing data with Pew. Based on the study's findings, when an AI overview -- AIO -- appeared in search, users were less likely to click on links when compared to queries that didn't generate AI summaries. Pew t

Meta Is Breaking OpenAI $100 Million at a Time

The artificial intelligence landscape, once characterized by collaborative innovation, has dramatically shifted into an all-out war for top talent. At the forefront of this aggressive new era stands Mark Zuckerberg’s Meta Platforms, orchestrating an unprecedented assault on rival OpenAI. This isn’t merely a recruitment drive; it’s a clear declaration of war, fueled by a staggering $300 million offer designed to dismantle the very core of its competitor. The Wall Street Journal is reporting that

Conspiracy theorists don’t realize they’re on the fringe

It's not that believers in conspiracy theories are massively overconfident; there is no data on that, because the studies didn't set out to quantify the degree of overconfidence, per Pennycook. Rather, "They're overconfident, and they massively overestimate how much people agree with them," he said. Ars spoke with Pennycook to learn more. Ars Technica: Why did you decide to investigate overconfidence as a contributing factor to believing conspiracies? Gordon Pennycook: There's a popular sense
