DEFROSTING car windows is a headache in winter, but now a solar-powered solution could let windows defrost themselves. Thomas Schutzius at ETH Zurich in Switzerland and his colleagues have developed a nanometres-thin coating made from gold and titanium dioxide. The tightly packed gold particles are good absorbers of sunlight and embedding them in titanium dioxide enhances this trait. The material fights ice by concentrating solar energy into a small volume, raising the temperature at its surface and leading to rapid defrosting. It can be deposited on glass and other materials. Crucially,
