flag A 2025 study claiming Italian spruce trees sensed a solar eclipse 14 hours early is dismissed by scientists as flawed and pseudoscientific.

flag A 2025 study claiming spruce trees in Italy sensed a solar eclipse 14 hours in advance has been dismissed as pseudoscience by plant scientists, who say the observed electrical activity was likely caused by a nearby thunderstorm, not anticipation. flag Critics argue the eclipse’s minimal light reduction—10.5%—was no greater than a cloudy day, making evolutionary prediction implausible. flag They highlight flaws in the study’s small sample size, lack of controls, and failure to account for weather events. flag The research, which suggested trees communicated or remembered eclipses, is seen as overreaching without rigorous evidence. flag Experts urge caution in interpreting plant electrical signals and stress the need for better experimental design and replication.
