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 presented new findings at the European Society of Cardiology meeting showing that laughter therapy can improve some measures of heart health in people with coronary artery disease. In the study, patients took part in guided laughter sessions while researchers measured inflammation markers and cardiovascular performance before and after. The reported results included lower inflammation and improved indicators of heart function after the laughter interventions.
