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.
Digital healthcare devices and wearable electronic products need to be thoroughly tested, lest they live short, ignominious lives, an expert will tell attendees at UBM’s upcoming Designers of Things conference in San Jose, Calif.
