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.

Researchers at King’s College London have reported links between irregular sleep patterns and changes in the gut microbiome. The study focused on “social jet lag,” where people shift their sleep timing between workdays and free days. Even a 90‑minute difference in the midpoint of sleep was associated with a microbiome profile that other studies have connected to poorer health, and the team also found associations with diet quality, eating habits and inflammation.

Meta, the company that owns Facebook and Instagram, says it will start asking users in the European Union for permission to show personalized advertising. The move follows regulatory rulings that challenged Meta’s data-collection methods for targeted ads. Rather than relying on a “legitimate interest” justification, Meta has conceded it must obtain explicit consent under EU data-protection rules before using people’s personal data to tailor ads on its platforms.

Linguists have long thought that social context shapes grammar: communities with many non-native speakers, like trade hubs, were believed to favor simpler, easier-to-learn systems, while isolated, homogenous groups develop dense, specialized grammatical rules. A new study compiled measurements across about 1,300 languages to test whether languages used mainly by “societies of strangers” indeed show reduced grammatical complexity compared with languages used in more stable, insider communities.
