Spain's annual Tomatina festival draws thousands each year to the town of Buñol, where participants playfully pelt one another with overripe tomatoes. This year about 15,000 people, many tourists, threw roughly 120 tonnes of fruit, turning streets and buildings into red pulp. The event lasts about an hour, and people commonly wear goggles and old clothes; there is a small participation fee of about €12 to help manage the crowd.

Google is expanding a tool called "Results about you," first introduced last year to help people remove personal information from Search results. The new version will actively scan the public web for instances of a user’s personal data and send alerts so they can request removal. Google says the feature is currently available in the United States in English and will be rolled out to more regions over time.

Scottish nationalists argue that Scotland shares more in common with Nordic countries than with the rest of the United Kingdom. A YouGov poll found that between 52% and 61% of prospective SNP voters say Denmark, Finland, Iceland, Norway or Sweden are somewhat similar to Scotland, while only 31% of that group say England is similar. Those views are often cited to support calls for closer social and political alignment with Scandinavian models.

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.
