12TB of decade-old Steam2 game build data leaks from public repository

Roughly 12 terabytes of data from Valve's old Steam2 backend, covering games published between 2003 and 2013, has surfaced online after being left exposed in a public repository. The trove reportedly includes prototype builds like an early version of Left 4 Dead with a different HUD, materials tied to the canceled Half-Life 2: Episode 3, and files from non-Valve titles such as Grand Theft Auto 5. Content creators covering Valve say no hacking was involved, and only game data was exposed, not player information.

Instagram to reduce reach of AI-generated profiles that skip new disclosure label

Instagram is renaming its 'AI creator' tag to 'AI-generated profile' and will limit the visibility of accounts featuring AI-generated people who fail to disclose it. Creators who add the new label won't face any reach penalty, but the rule only applies to profiles built around a fully AI-generated person, not those simply using AI tools for editing or captions.

Medieval physicians ranked foods as hot, cold, wet or dry to guide health

Historical texts show medieval Europeans followed Galen's belief that food was central to medical treatment, classifying foods by their supposed qualities of hot/cold and wet/dry to determine their effect on the body. Physicians taught that eating properly balanced these qualities and prevented illness, tied to a theory of three-stage digestion occurring in the stomach, liver, and throughout the body. Diet quality also reflected social class, with the wealthy eating fine wheat bread while poorer people relied on coarser barley or rye.

Researchers link stress resilience to circadian, cellular and seasonal cycles

New guidance outlines how stress resilience fluctuates based on biological rhythms operating at multiple levels, including cellular processes, daily circadian patterns, and broader seasonal shifts. The framework suggests a three-step approach to building resilience by aligning habits and expectations with these natural cycles rather than treating stress capacity as constant year-round.

Apple's Phil Schiller steps down as App Store chief amid executive exodus

Phil Schiller, who has led Apple's App Store since 2015 and joined the company in 1987, has stepped down from that role, according to Bloomberg.

Google auto-expands AI Overviews with built-in AI Mode prompt box on desktop

Google Search is now showing some AI Overview answers fully expanded by default on desktop, complete with an 'Ask anything' box that launches AI Mode conversations.

The change, spotted by an SEO consultant and unconfirmed by Google, currently seems limited to desktop searches for definitions and similar queries.

BoE's Bailey Tells G20 Frontier AI Poses Top Cyber Risk to Finance

Bank of England Governor Andrew Bailey, writing as chair of the Financial Stability Board, told G20 finance officials that cutting-edge AI models could sharply increase the speed, scale and affordability of cyberattacks on the financial system. He warned that many countries still lack rules to govern how these advanced models are developed, released and deployed, leaving the sector exposed.
