"a professor at the university of california san diego recently explained the inexorable physical principles that govern the tendency of everything from rope to proteins, even dna, to form knots. but science trumps nature. materials called electroactive polymers change shape when supplied with electric voltage. cables constructed with cleverly integrated electroactive polymer components could lead to headphones that don’t tangle, as well as to self-straightening extension cords and garden hoses. added bonus: fast holiday decorating. you’ll never have to hunch over a hopeless mass of christmas lights again."
