Discover the better, faster, stronger (okay, not faster) materials of the future, and Thomas Edison’s ill-conceived plan to turn concrete into furniture.
Plus, printing objects in 3D… the development of artificial skin… and unearthing the scientific contributions of African-American women chemists.
