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.

A recent YouGov–Cambridge Globalism Project survey finds that voters in Western democracies are more divided by identity and partisan loyalty than by specific policy positions. Researchers describe strong "affective polarization": people feel intense dislike for opposing groups even when those groups often share similar views on key debates such as sexism, racism, and economic policy. The findings challenge the idea that culture wars are mainly about conflicting opinions; instead, much conflict appears driven by who people see as "us" versus "them."

Researchers studying more than 15,000 people report that higher physical fitness is linked to a lower chance of developing atrial fibrillation, an irregular heartbeat that raises the risk of stroke fivefold. The study, presented at the ESC Congress 2023, used treadmill exercise tests to estimate fitness in metabolic equivalents (METs) and followed participants over time to see who developed heart rhythm problems or strokes.

Scientists have identified Burgessomedusa phasmiformis as the oldest known swimming jellyfish, based on fossil specimens recovered from the Burgess Shale in Canada. These animals lived more than 500 million years ago during the Cambrian period. Researchers classify them as medusozoans, the group that includes modern jellyfish, and say the fossils provide direct evidence that jellyfish-like animals had already evolved by that time.
