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.

On Saturday at Thredbo Ski Resort in New South Wales, a chair on the Kosciuszko chairlift detached after what the resort described as an unexpected gust of wind. The Kosciuszko is Australia’s longest ski lift. Three snowboarders in their twenties—two women and one man—fell several metres onto the snow near Eagles Nest and suffered facial and back injuries. Resort staff and emergency responders attended the scene; the incident has been described by Thredbo as isolated and unusual.

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."
