Scientists have long-suspected an association between trees and electricity but researchers from Queensland University of Technology (QUT), in Brisbane, Australia, think they may have finally discovered the link. Dr Rohan Jayaratne and Dr Xuan Ling from QUT's International Laboratory for Air Quality and Health (ILAQH), led by Professor Lidia Morawska, ran experiments in six locations around Brisbane, including the Brisbane Forest Park, Daisy Hill and Mt Coot-tha.
