Two new studies presented at the European Society of Cardiology’s annual meeting found links between consuming ultra-processed foods and higher risks of heart disease, including heart attacks and strokes. Ultra-processed foods are widely available consumer items such as fizzy drinks, many breakfast cereals, packaged snacks and ready-made meals. One analysis reported that a 10 percent increase in daily ultra-processed food intake was associated with about a 6 percent rise in risk of cardiovascular disease.

An annual YouGov-Cambridge Globalism Project survey, reported by The Guardian, finds that support for populist ideas has fallen across several European countries over the past three years. The survey measures attitudes like distrust of elites, favoring strong national control, and opposition to immigration. In the latest cycle, populist sentiment declined in ten European nations, indicating fewer people now express broad populist beliefs than in earlier years.

Mick Jagger, the longtime frontman of the Rolling Stones, has been sharing unexpectedly ordinary moments from his tour life on Instagram. Instead of the usual glamorous or staged celebrity photos, his feed shows mundane outings—visits to local attractions, bars, strip malls and well‑known landmarks. He told The Washington Post that these images are less about spectacle and more about getting a feel for places, and he treats the account like a simple visual diary.

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.
