## Resource

Scientists at Tohoku University challenge traditional aerodynamics, discovering that microscopic roughness can significantly reduce drag on surfaces. Their innovative method, DMR, delays the transition from smooth to chaotic airflow, primarily tackling frictional resistance. This breakthrough, made possible by a new levitating wind tunnel, could lead to substantial fuel savings and reduced emissions for high-speed vehicles.
