Advances in technology have allowed for some high-tech ways to monitor air quality, from satellites that orbit the Earth to art installations that light up when pollutants are low. Scientists at the University of Utah have come up with a relatively low-tech solution, demonstrating how the buildup of magnetic particles on tree leaves can be used to gauge the quality of the surrounding air.
