Completing the story they started by creating synthetic magnetic fields,* scientists from the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland, have now made atoms act as if they were charged particles accelerated by electric fields. Reported in the journal Nature Physics,** these synthetic electric fields make each atom in a gas act, individually, as if it were a charged particle, but collectively they...

Tomorrow's nonvolatile memory devices "“ computer memory that can retain stored information even when not powered "“ will profoundly change electronics, and Cornell University researchers have discovered a new way of measuring and optimizing their performance. Using a very fast oscilloscope, researchers led by Dan Ralph, the Horace White Professor of Physics, and Robert Buhrman, the J.E. Sweet Professor of Applied and Engineering Physics, have figured out how to quantify the...

Massive waves in giant magnetic holes on the surface of the Sun have been discovered for the first time by solar scientists from the University of Sheffield and Queen´s University Belfast, something that will bring experts a step closer to unlocking the secrets of the Sun. The Sun is interwoven by a complex network of magnetic field lines that are responsible for a large variety of fascinating features that can be seen in the solar atmosphere. Large, dark regions, which...

From the very first moments of life, hatchling loggerhead sea turtles have an arduous task. They must embark on a transoceanic migration, swimming from the Florida coast eastward to the North Atlantic and then gradually migrating over the course of several years before returning again to North American shores. Now, researchers reporting online on February 24 in Current Biology, a Cell Press publication, have figured out how the young turtles find their way. "One of the great mysteries of...

Physicists propose beaming laser at atmospheric sodium to measure global magnetic field Mapping the Earth's magnetic field "“ to find oil, track storms or probe the planet's interior "“ typically requires expensive satellites. University of California, Berkeley, physicists have now come up with a much cheaper way to measure the Earth's magnetic field using only a ground-based laser. The method involves exciting sodium atoms in a layer 90 kilometers above the surface and measuring...

Nuclear magnetic moment provides a highly sensitive probe into the single-particle structure and serves as a stringent test of nuclear models. In recent decades, the facilities with radioactive ion beam models to study nuclear magnetic moments make it possible to measure the magnetic moments of neutron-rich and proton-rich nuclei with high precision. On the theoretical side, many nuclear structure models, including advanced shell models, and self-consistent mean-field theories, have succeeded...
