Engineer Dave Bloomquist may make the people living and working in buildings surrounding Ground Zero in New York City feel a little safer. The University of Florida professor is assessing the structural integrity of buildings surrounding the World Trade Center, providing more detailed and accurate information than has ever been available to recovery workers. The entirely new technique uses airborne laser swath mapping (ALSM) and ground-based laser scanning. Bloomquist's technique combines millions of laser measurements with aerial and digital images of New York City into a three-dimensional model. "Several surrounding buildings near Ground Zero may not be structurally salvageable," says Bloomquist. "There is concern that several are slowly deteriorating." He is also analyzing the Pentagon for signs of structural damage. For more information, go to www.ufl.edu.
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.
