A study covered by The Conversation had 58 adults cycle while wearing devices from Apple, Samsung, Garmin, and Fitbit alongside a metabolic analyzer that measures actual gas exchange to determine calorie burn. Comparing the watches' estimates to that gold-standard measurement, researchers found substantial inaccuracies, with errors reaching 100% or more in some cases, particularly among people with higher body fat percentages.
Discord says it is now automatically sorting accounts into age groups using signals like account age and server membership, rather than message content, meaning over 90% of users won't need to verify their age. Adult accounts see no change, while teen accounts (13-17) retain core features like messaging and voice calls but are blocked from age-restricted content and settings. Users who need to confirm their age can now do so via methods like credit cards, app store age-sharing, Google Wallet, or AgeKey, without submitting an ID or selfie.
South Korea's K-pop industry is increasingly incorporating artificial intelligence and robotics into aspects of music creation and live performance. The move has drawn scrutiny from fans and performers who have voiced concerns about the technology's role in an industry built on human artistry.
OpenAI has rolled out two new GPT-6 tier models, Sol and Luna, to Codex and ChatGPT Work following its earlier release of the flagship GPT-6 Astra model this month. Both models use fewer tokens than their GPT-5.6 equivalents, with Sol aimed at complex coding and agentic tasks and Luna suited to high-volume, focused work. The rollout covers Plus, Pro, Business, Enterprise and Edu accounts, with Free and Go users able to access Luna via the desktop app, though Enterprise admins must enable access.
Director Zach Cregger said altering one small detail in the ending of a film significantly improved it. He did not specify further plot details in the available reporting, but attributed the improvement directly to this single change.

Nvidia CEO Jensen Huang told CBS he sees no chance of a catastrophic AI scenario unfolding by 2030, calling some AI industry leaders' warnings irresponsible and unnecessarily frightening to the public. He suggested that frontier AI labs pushing for new regulations may be doing so to sidestep accountability under existing laws.
An Entrepreneur contributor argues that employees promoted for their technical mastery and problem-solving skills often struggle as leaders because those same traits — perfectionism, taking over, black-and-white thinking — alienate teams. The piece describes a pattern where new managers interrupt, dismiss contributions, or overcorrect, causing talented staff to disengage or leave.
General ergonomic advice recommends positioning a computer monitor roughly an arm's length away from the body, close enough that outstretched fingers can touch the screen. The guidance also covers keeping the display at eye level with an appropriate tilt, with adjustments suggested depending on monitor size.
OpenAI has updated its smaller GPT-6 models, Sol and Luna, following this month's launch of the flagship GPT-6 Astra. The company says API access to the new Sol and Luna models costs half as much as the previous 5.6 series, citing gains in caching and inference, and claims GPT-6 Sol makes roughly half as many factual mistakes as its predecessor while also reducing coding errors.
A writer describes a personal hobby of exploring random locations on Google Street View, including comparing current and historical captures of the same spots. In one example, a Nissan 350Z appears parked on the same narrow Tokyo street in every Street View capture dating back to 2009, based on the writer's review of Google's archived imagery.
Hacking group ShinyHunters told 404 Media it breached FBI-related systems and obtained personal data on all FBI employees and applicants, including names, home addresses, phone numbers, birthdates and spouse details.

ShinyHunters also defaced the FBI's jobs website on Tuesday.
