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 led by Itzhak Khait at Tel Aviv University have found that some plants produce audible, high-frequency sounds when they are stressed or damaged. The team tested tomato and tobacco plants and recorded ultrasonic clicks that arise during drought stress or after cutting. Sensitive microphones and acoustic analysis allowed detection of these sounds from as far as five meters, suggesting plants may broadcast information about their physical condition.

A Kansas judge has ordered authorities to delete all electronic copies made from files seized during a police search of the Marion County Record, a small local newspaper. The searches, carried out nearly two weeks earlier, removed computers and cellphones from the paper’s office. The court order requires that digital copies created from those devices be destroyed, limiting how officials may keep and use material gathered in the raid.
