Living things are asymmetrical, even at the molecular level: Although many essential biomolecules exist in distinct mirror-image forms, cells tend to use just one of those forms exclusively. An article in Quanta Magazine sheds light on the concept of chirality and research into its origins involving primordial magnetism. A few excerpts of the fascinating article here: […]
Depending on how they interact with magnetic fields, most materials are classified as diamagnetic, paramagnetic, ferromagnetic, ferrimagnetic, or antiferromagnetic. We love the article by Mike Gedeon, customer technical services manager of Materion Performance Alloys and Composites, that explains these different kinds of magnetic properties and related aspects such as magnetic susceptibility. A few highlights follow. […]
Some magnets are heavier than others. Handling them can be a challenge, in this case tackled by Wimmer Maschinentransporte of Germany. They can take longer to make, too. Two recent examples from the engineering and manufacturing facilities of Bilfinger Noell are the 13-ton monster PERC magnet shown, in part, above, and a superconducting “Wiggler” recently delivered to Brookhaven National Laboratory. […]
Undeterred by a massive volcanic eruption on the island of La Palma in the Canary Islands, scientists are proceeding with their plans to build the European Solar Telescope there in pursuit of learning more about […]
Laura Greene, chief scientist at the National High Magnetic Field Laboratory, has been appointed to serve on the President’s Council of Advisors on Science & Technology. Also a professor of physics at Florida State University where the laboratory is headquartered, she […]
Maximizing image quality is a given in any new magnetic resonance imaging scanner. Delivering that capability to the maximum number of patients and doing it cost effectively, however, depends on optimizing workflows and maximizing scanner up-time. Many radiology departments are currently under extreme pressure to perform more MRI scans on more patients, not only due to the aging population but also to deal with the backlog of cases resulting from the Covid-19 pandemic.
