Researchers at Speech Graphics, UC San Francisco and UC Berkeley report a brain–computer interface that helped a woman who lost speech after a stroke communicate again. Tiny electrodes were placed on the surface of her brain to record neural activity while she attempted to speak. That recorded activity was decoded into written text, a synthetic voice and real-time facial animation using software originally developed for video-game characters such as those in The Last of Us Part II and Hogwarts Legacy.

Online tools now let anyone view past versions of websites, exposing changes that site owners may have made over time. The Wayback Machine at archive.org stores snapshots of millions of pages, while archive.today preserves copies that sometimes survive when other archives don’t. The Memento Project links these services and helps users search by URL and date, making it easier to see how pages, policies, and content evolved.

Researchers reviewing clinical trials have found little evidence that blue‑light filtering glasses provide the sleep or short‑term eye‑comfort benefits often claimed by makers and some retailers. The review pooled data from 17 randomized trials and reported no consistent short‑term reduction in visual fatigue from computer use, and it could not show clear benefits for sleep quality, vision performance, or long‑term retinal health.

A recent YouGov–Cambridge Globalism Project survey finds that voters in Western democracies are more divided by identity and partisan loyalty than by specific policy positions. Researchers describe strong "affective polarization": people feel intense dislike for opposing groups even when those groups often share similar views on key debates such as sexism, racism, and economic policy. The findings challenge the idea that culture wars are mainly about conflicting opinions; instead, much conflict appears driven by who people see as "us" versus "them."
