China breaks quantum physics record, transmits entangled photons over 1 200 km

For the first time, scientists have realized the satellite-based distribution of entangled photon pairs over a distance of 1 200 km (745 miles). The photon pairs were demonstrated to be still entangled after traveling long distances and Bell's inequality was...

seasonal asymmetry birkeland currents

Birkeland currents stronger in the northern hemisphere, vary with the season

ESA’s Swarm mission has discovered that this seasonal variation of Birkeland currents, strong electric currents in the upper atmosphere, is not the same in the north and south polar regions. Named after Kristian Birkeland, the scientist a century ago who first...
