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.

William Friedkin’s 1977 film Sorcerer is a tense thriller about four desperate men hired to transport highly unstable explosives across dangerous, remote roads. Inspired by Georges Arnaud’s novel and echoing the earlier French film The Wages of Fear, Sorcerer aimed for a raw, realistic tone. Friedkin, fresh from the success of The Exorcist, pushed for authentic locations and intense performances to heighten the film’s unrelenting atmosphere.

The Maillard reaction is the chemical process that browns food and creates complex flavors when we cook. New research led by Professor Caroline Peacock at the University of Leeds reports that a similar reaction can occur in the deep ocean. There, it converts small organic carbon molecules into larger, stable polymers. The study, published in Nature, estimates this process locks away roughly four million tonnes of organic carbon each year.
