US Navy announces sea trials for electromagnetic railgun: "Watching old war movies, we expect firing a navy gun to be accompanied by a deafening bang and a dramatic cloud of burnt powder. This being the 21st century, the US Navy has other ideas as it prepares to install and test a prototype electromagnetic railgun on a Spearhead-class joint high speed vessel (JHSV) in 2016 as part of a program to develop the naval artillery of the future"

BAE Systems develops a flat lens that acts like it's curved

BAE Systems develops a flat lens that acts like it's curved: "Anyone who’s ever needed a pair of thick eyeglasses has a firm idea that lenses are the one thing where form follows function. However, BAE Systems and Queen Mary’s School of Electronic Engineering and Computer Science in London have put paid to that idea with a flat lens that works like a conventional curved lens, yet without any reduction in bandwidth performance. Using a combination of composite metamaterials and transformational optics for the first time, they have created a lens that's able to bend electromagnetic waves, yet isn't bound by its shape for its function."
