University of Maryland study finds global tree cover grew by 2.24 million sq km since 1982

A satellite-based analysis led by Xiao-Peng Song and Matthew Hansen at the University of Maryland found that global tree cover increased by roughly 2.24 million square kilometers, an area comparable to Texas and Alaska combined, between 1982 and 2016. The gains, concentrated in temperate, boreal, and subtropical zones, offset major losses in tropical forests caused by deforestation, fire, and drought.

Explainer: How VESA mounting patterns determine TV wall-mount compatibility

VESA patterns refer to the standardized spacing, in millimeters, between the threaded mounting holes on the back of a TV, given as horizontal by vertical measurements. This spacing is unrelated to screen size or resolution, so buyers should check their exact TV model rather than assume a pattern based on display dimensions. Most wall mounts support several VESA patterns, so a bracket doesn't need to match one exact size as long as the TV's pattern is on its supported list.

OpenAI's Teen ChatGPT Version Draws Fresh Safety Questions

OpenAI has rolled out a version of ChatGPT tailored for teenage users, prompting renewed scrutiny over how the company safeguards younger users from harmful content. Critics and safety advocates are questioning whether the age-specific controls are sufficient given ongoing concerns about AI chatbots' interactions with minors.

Pngine: New S-Expression Format Turns WebGPU Code Into Runnable PNG Files

An independent developer has released pngine, a declarative language and runtime built over 2.5 years that lets programmers describe WebGPU shaders and pipelines using S-expressions mirroring the WebGPU spec directly. The tool validates configurations via WGSL reflection without needing a live GPU context, offers an LSP for real-time error checking, and can export projects as a single HTML file, a ZIP, or even a self-contained PNG image holding compiled bytecode.

Advice column urges teens to master LLM fundamentals from first principles

An opinion piece argues that a 17-year-old today should focus on building large language models from scratch rather than just using them, in order to understand their capabilities and limits. The author notes LLMs excel at tasks like writing essays but fail at physical, real-world tasks like cleaning a room, and suggests pursuing college and graduate study aimed at closing that gap. The piece frames this as a path toward developing new architectures beyond current LLMs for physical-world learning.

Mophie launches PowerStation Plus battery banks with built-in USB-C cables

Mophie has released four new PowerStation Plus power banks in Standard and Signature finishes, each available in 5000mAh and 10000mAh capacities. Every model includes at least one integrated, non-retractable USB-C cable, with the top-tier Signature 10K version offering two braided cables and support for charging three devices simultaneously. Prices range from $29.95 to $59.95 on Amazon.

Unidentified 'Ox Alpha' AI model on OpenRouter sparks guessing game over its maker

A free, high-performing AI model called Ox Alpha appeared on OpenRouter this week, listed only as a 'stealth model' built by an anonymous third party for coding and agentic tasks. Stripe CEO Patrick Collison praised it publicly, fueling widespread speculation across X and Reddit about its origin, with theories ranging from China's Z.ai GLM models to an unreleased Microsoft MAI build.

Apple offers iPhone settings to stop Siri interrupting CarPlay drives

Apple's iOS settings allow drivers to customize or silence Siri's behavior during CarPlay use, including disabling announced messages, skipping reply confirmations, and preventing Siri from stopping mid-sentence due to background noise. Options are found under Notifications, Accessibility, and Apple Intelligence & Siri menus in the iPhone's Settings app.

AI Art Training Rubric Failure Traced to Redundant Reward Signals

A team training a generative model to paint with code (using p5.brush) found their nine-signal reward rubric caused the model to plateau at flat, repetitive outputs. Investigation revealed four quality judges and prompt adherence were nearly identical measurements, while a code-length metric saturated early and stopped providing useful feedback, leaving only one signal actually driving learning. The fix replaced absolute 0-10 scoring with pairwise comparisons against a curated pool of 1,664 hand-rated reference images.

Dutch regulator fines Uber €825 million over automated driver deactivations

The Dutch Data Protection Authority has fined Uber roughly $966 million for deactivating driver accounts through automated systems without adequate human review or warning, marking one of the largest penalties issued under GDPR. The investigation stemmed from complaints, including one from former French Uber driver Brahim Ben Ali, who gathered testimony from 170 other drivers alleging similar treatment. Uber disputes the regulator's findings and plans to appeal the fine.
