Researchers at Northwestern University are studying superconductors using a hybrid magnet weighing 34 tons and standing 22 ft tall at the National High Magnetic Field Laboratory in Tallahassee, Florida. The huge magnet improves the imaging of high-temperature superconductors so much that William Halperin, a professor of physics and astronomy, saw the cores of vortices, which he describes as tiny electrical tornadoes swirling in the superconductor's copper oxide compound. His findings include evidence of an electronic Doppler effect. The professor is hoping to improve resolution of MRI machines used in hospitals. For more information, visit www.northwestern.edu.
A simple new chemical method for repairing and recycling notoriously difficult carbon fiber composites has been developed by the Fraunhofer Institute for Applied Polymer Research. An entire component can be completely recycled, including reclaiming its expensive carbon fibers for reuse.
In today’s connected world we are seeing the beginning of connected homes, smart grids, self-driving automobiles, drones, and many other amazing devices. Out of all the soon-to-be connected devices, which device poses the greatest dangerous to its users and society?
