Researchers build synthetic materials that ‘learn’ to change shape

When you exercise, your muscles go stronger. When you sow a plant, its stem volition crook truthful that its leaves get much sunlight. Both these changes are examples of adaptation — erstwhile a biologic worldly senses its environment, past reorganises its interior operation to past better. All beingness indispensable accommodate implicit clip to changing conditions. Populations that don’t could go extinct.

However, astir non-living materials bash not actively set their interior operation successful effect to caller conditions aft they are made. When a metalsmith forges a barroom of steel, its interior operation is mostly fixed from that constituent on, though it tin inactive alteration owed to heat, stress, etc. If you privation a caller barroom with antithetic properties, you request to technologist it anew.
