Magnets to reveal dark-matter fluid

摘要

Every underdog has its day. Using the same underlying physics as MRI scanners, a new experiment could boost the search for one of the humbler dark matter candidates: the axion. Most hunts for dark matter focus on detecting individual, highly elusive particles known as WIMPs. The runner-up is the axion, which should behave more like a background fluid - and is even harder to find.
