Science is not an entity capable of self-awareness and therefore can not concive falsehoods. What you're referring to as lies are either mistakes made by people in scientific fields that are later corrected through better resurch and experiments with better techniques and equipment or published "scientific articles" that are just propaganda fended by large corporations to preserve their image or push their agenda. Example, coke funding articles that sugar and soda don't make people fat, or how cigarette companies paid off doctors to calim their products weren't related to lung cancer.
