"Significant changes" in the weapons mix of the U.S. Navy are needed during the next 25 to 35 years. So reports a National Research Council panel on naval weapons. The study calls for increased use of smart weapons, stealth, and electronic warfare. Needed is a family of low-cost, high-volume, long-range precision ballistic weapons for surface-to-surface operations. Also recommended: a new air-to-air weapon, mines operated by networked sensor systems, and an array of non-lethal weapons. More emphasis should be put, the panel says, on undersea weapons optimized for offensive and defensive operations in coastal regions. In the future, it adds, a greater percentage of ordnance will ride on standoff air-to-surface weapons. These weapons must receive target information from off-board sensors, as well as have autonomous capabilities to continue their attack in the face of countermeasures.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
