Studies of one of the galaxy's most active black-hole binaries reveal a dramatic change that will help scientists better understand how these systems expel fast-moving particle jets.
Plasmonic material that would, with adjustments to its temperature and/or magnetic field, either stop a terahertz beam cold or let it pass completely was discovered.
Experimental evidence found for a universal quantum mechanism that allows trios of particles to appear and reappear at higher energy levels in an infinite progression.
