Fans of colloid chemistry (c'mon, who isn't one?) will be particularly psyched by the work of a team of German researchers. They've produced new particles that could lead to car finishes (or cosmetics) that can change color based on temperature or humidity. We'd imagine the allure of such a product would be lost on our SoCal audience, but us four-season types could soon have a new way to lose our cars in parking garages.
