Researchers from the University of California, San Diego (UCSD) are taking inspiration from nature in the search for new materials that could one day be used to create body armor. The study, supported by the US Air Force, focuses on the unique structure and strength of the hexagonally-scaled shell of the boxfish.
The age of steam is over – at least, as far as US aircraft carriers are concerned. At Newport News, Virginia, the USS Gerald R Ford (CVN 78) successfully test fired a revolutionary Electromagnetic Aircraft Launch System (EMALS), which replaces the steam catapults that have been standard carrier equipment since the 1950s. The test made a literal splash because it involved an unmanned dead-weight sled rather than an aircraft, which landed about a hundred yards off the bow of the still under construction vessel.
