How Scientists' Ability to Adapt Led to New Insights into Magnetism
With time scheduled to use a certain beamline at the National Synchrotron Light Source-II (NSLS-II), scientists from NSLS-II and their partner institutions faced a challenge. They planned on researching a special type of region in magnetic materials that could be useful for next-generation computers. Regions in magnetic materials - called magnetic domains - determine a material's magnetic properties. The scientists wanted to study how these magnetic domains changed over time under the influence of an outside magnetic field.

UAH Researchers Using Pulsar Measurements to Probe Dark Matter Find Milky Way Galaxy Is Highly Dynamic
Dark matter comprises over 80% of all matter in the cosmos but is invisible to conventional observation, because it seemingly does not interact with light or electromagnetic fields. Now Dr. Sukanya Chakrabarti, the Pei-Ling Chan Endowed Chair in the College of Science at The University of Alabama in Huntsville (UAH), along with lead author Dr. Tom Donlon, a UAH postdoctoral associate, have written a paper to help illuminate just how much dark matter there is in our galaxy and where it resides by studying the gravitational acceleration of binary pulsars. Chakrabarti gave a plenary talk on this work and other methods to measure galactic accelerations at the 243rd meeting of the American Astronomical Society in New Orleans in January.
Shaping the Future: A New Technique for Sorting Micro-Particles Unveiled
Thanks to the rapid progress in tiny tech, we've been mainly using microfluidics to sort tiny particles by size. But now, there's a new way to sort them by shape, which could be a big deal for medical tests and chemistry. This study shows off a new method using sound waves to separate oddly shaped particles from round ones, without needing any labels.
Super Strong Magnetic Fields Leave Imprint on Nuclear Matter
A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, provides the first direct evidence of the imprint left by what may be the universe's most powerful magnetic fields on "deconfined" nuclear matter. The evidence comes from measuring the way differently charged particles separate when emerging from collisions of atomic nuclei at this DOE Office of Science user facility.
