A Method for Detecting Quantum Gravity Effects? Interesting….

BBC News is trumpeting1 an article just published in Nature Physics describing a method for performing gravity-resonance-spectroscopy2. This work builds upon work published in 2002 involving the motion of slow-moving neutrons3, and may actually provide a method for discovering and studying axions4.
