The National Science Foundation is funding a collaborative effort between NASA and the University of Buffalo's Department of Physics to develop a new type of shock-absorbing system that may one day protect skyscrapers, bridges, shops, and automobile bumpers from powerful impacts. Surajit Sen, an associate professor of physics at the university, designed the new shock-absorbing system that consists of a long, cone-shaped chain of spheres. The sphere positioned closest to the expected source of a shock impulse is the largest. Each subsequent sphere is slightly smaller, with the smallest sphere positioned closest to the thing needing protection from shock. As mass is reduced, the energy of the impulse is distributed, according to Sen. He envisions a structural material embedded with chains of the spheres.

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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
