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.
In his keynote address at the RAPID 2015 conference last week, Made In Space CTO Jason Dunn gave an update on how far his company and co-development partner NASA have come in their quest to bring 3D printing to the space station -- and beyond.
On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
