For the first time today, Sound Transit's Link light rail will make stops in Kent, Des Moines, and Federal Way, the first big push into the South Sound.

In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism are related. A new study revealed that the magnetic component of light exerts a surprising influence on matter, affecting 17 percent of atomic spin in the visible spectrum and up to 75 percent in the infrared.

The Nordic countries are no strangers to the long, dark winter. Despite little to no daylight — plus months of frigid temperatures — people who live in northern Europe and above the Arctic Circle have learned how to cope mentally and physically with the annual onset of the winter blues,

The APS Electric Light Parade is set to meander through Phoenix, spreading cheer with its bright displays. It will also close some busy streets.

Researchers from the School of Physics at Wits University, working with collaborators from the Universitat Autònoma de Barcelona, have demonstrated how quantum light can be engineered in space and time to create high-dimensional and multidimensional quantum states.
