The double helix of DNA is one of the most iconic symbols in science. By imitating the structure of this complex genetic molecule we have found a way to make artificial muscle fibres far more powerful than those found in nature, with potential applications in many kinds of miniature machinery such as prosthetic hands and dextrous robotic devices.
The power of the helix
DNA is not the only helix in nature. Flip through any biology textbook and you’ll see helices everywhere from…
