Scientists have developed material that can drive mechanical systems, with movements controlled by a pattern set into the design. Potential applications include opening windows in humidity, and allowing fabric to evaporate sweat
Engineers have developed a high-throughput computational method to design new materials for next generation solar cells and LEDs. Their approach generated 13 new material candidates for solar cells and 23 new candidates for LEDs.
Star formation within interstellar clouds of gas and dust, so-called molecular clouds, proceeds very rapidly yet highly 'inefficiently'. Most of the gas is dispersed by stellar radiation, revealing galaxies to be highly dynamic systems, like 'cosmic cauldrons', consisting of components that constantly change their appearance. A team of scientists has reached these conclusions based on new observations of the NGC 300 spiral galaxy.
