(Phys.org)—An international team of astronomers and astrophysicists has found some unusual spectral activity involving an otherwise "normal" pulsar; it displayed some absorption lines, which generally only occurs with bodies ...
Computer chips that use light to move data would be much more energy efficient and possibly even faster than today’s chips, which use electricity. One of the difficulties in realizing them, however, is that light moving ...
