Researchers at Yale University have succeeded in measuring an electric current flowing through a single organic molecule sandwiched between metal electrodes. The feat could pave the way for a new generation of transistors so small that a beaker full would contain more transistors than exist in the world today, or so reports team leader and Yale electrical engineer Mark A. Reed. To capture the historic measurement of current across a single organic molecule, the researchers made a mechanically controllable break junction by gluing a notched gold wire to a flexible substrate. They then fractured the wire to make an adjustable gap. Next, they sandwiched a single molecule of benzene flanked by two sticky sulfur atoms between the two gold electrodes. What's the potential results? "Thousands of silicon transistors can be produced now for less than a penny," Reed explains, "but the dramatic decrease in cost per transistor that we've enjoyed over the last two decades will start to slow down soon." The answer, Reed believes, is to find materials that will assemble themselves into quantum components. E-mail firstname.lastname@example.org.
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.
