Researchers explain why AI-generated food images look so unappetizing

AI experts say the strange, unsettling appearance of AI-generated food photos stems from how diffusion models build images—starting with noise and forming rough shapes before adding fine texture. When the underlying structure is wrong, as with malformed hands, the model still layers convincing-looking detail on top, producing food that looks structurally off despite realistic textures. Researchers from Oxford and the University of Naples note these models also struggle with thin, continuous shapes, compounding the issue.

RugOne's Xsnap 7 Pro rugged phone has a detachable magnetic action camera

RugOne, part of Ulefon, unveiled the Xsnap 7 Pro, a rugged smartphone featuring a magnetic, removable camera module that doubles as an action cam. The 39-gram module shoots up to 2.7K/30fps, holds 64GB storage, runs 40 minutes per charge, and streams a preview to a companion app up to 50 meters away. The phone itself includes a 50MP main camera, a 64MP infrared night-vision sensor, a 6.67-inch 120Hz display, IP68/IP69K durability ratings, and a MediaTek Dimensity 8400 chip.

153 Million Scanned Driver's Licenses Leaked from Verification Firm Over Yearlong Breach

A dark web identity-theft service is selling scans of more than 153 million U.S. and Canadian driver's licenses, apparently sourced from a Louisiana-based identity verification company that supplies age- and ID-checking services. Investigator Brian Krebs found the site was still adding hundreds of thousands of new records daily, including 400,000 added the day the breach was exposed, before the service was finally taken offline.

OpenAI's GPT-6 Astra launch stumbles, Altman apologizes to paying users

OpenAI rolled out its new GPT-6 Astra model first to enterprise customers with access to its Daybreak cybersecurity platform, delaying access for Plus and Pro subscribers who expected earlier availability. CEO Sam Altman acknowledged the rollout was 'messy' and apologized, while an OpenAI engineering lead offered subscription credits to affected users for each day access was delayed.

Tesla begins offering Cybercab rides via Robotaxi app in Austin

Tesla has started deploying its steering-wheel-free Cybercab for paid rides through its Robotaxi app, though so far only in Austin and only as one possible vehicle assigned by availability rather than by rider choice. The app also covers Dallas, Houston, Miami, Orlando and Tampa, but those cities currently get standard Model Y rides. Tesla holds permits for 314 driverless vehicles in Texas, with just 45 being Cybercabs, and it isn't clear how many are actually shuttling paying customers versus still being tested.

Nvidia sets October launch for RTX Spark laptops and desktops from seven PC makers

Nvidia used IFA to confirm that PCs built around its RTX Spark Arm-based SoC will ship starting in October, with partners now including Lenovo and Acer alongside previously announced Microsoft, HP, Dell, Asus and MSI machines. The lineup includes a flagship 6,144-CUDA-core, 20-core Grace configuration with up to 128GB of unified memory, plus a lower-tier laptop-only chip with 5,120 CUDA cores and 18 CPU cores.

MartyPC Developer Extracts NEC V20 Microcode via Die Photography

The developer behind the MartyPC emulator commissioned a 5.6-gigapixel die photograph of an NEC V20 CPU (fabricated by second-source manufacturer Sharp) to extract its microcode. The goal is to replace MartyPC's existing V20 emulation core, which was essentially a modified 8088 core rather than a true cycle-accurate model, with one based on the chip's actual internal logic.

Google Phone app beta shows Scam Detection coming to Xiaomi devices

Teardown of the latest Google Phone app beta (v237.0.973536915) reveals Xiaomi has been added to the list of supported manufacturers for Scam Detection. The AI-powered call-screening tool already works on Pixel phones and Samsung's Galaxy S26 series, with vivo support also expected soon. It's not yet clear which Xiaomi models will get the feature first, though a globally sold flagship is the likely candidate rather than the China-only Xiaomi 18 Fold.

Ugreen unveils HomeAgent smart home platform with local AI hub and Uliya voice assistant

Ugreen, best known for chargers and NAS storage devices, debuted its HomeAgent smart home system at IFA, combining camera storage, on-device AI processing, and home automation controlled by a new voice assistant called Uliya. The flagship MasterAgent MA100 hub doubles as a NAS device and smart home brain, using an Nvidia Jetson Thor T5000 chip capable of up to 2,070 TFLOPS of AI performance, with three hub tiers available.

OpenAI launches GPT-6 Astra, its first model rated 'Critical' for cybersecurity risk

OpenAI has released GPT-6 Astra, a new flagship model the company describes as state-of-the-art in areas like coding, browsing, science and professional tasks. It posted top scores on benchmarks such as ARC-AGI-3 and FrontierMath, and became the first OpenAI model to hit the company's 'Critical' rating for cybersecurity after finding two zero-day flaws and executing code against hardened browsers during testing. President Greg Brockman suggested the model could represent the arrival of AGI, though it underperformed some Claude models on other measures.
