Saw this posted to the Google+ LENR group. Seems interesting and has at least been accepted for publication in Physical Review D <http://journals.aps.org/prd/accepted/9c071Y13Qf01b540790037d706f539446ab0764e8>. The full paper is available on Arxiv <http://arxiv.org/pdf/1504.00333v3.pdf> .
They do propose a method of producing gravity through electromagnetism and detecting the effects. There does not seem to be any new physics proposed. Although the effect would be minuscule and likely of no practical value in the immediate future, they note: "Such a detection of the space-time curvature generated by a magnetic field in laboratory would constitute a major step in physics: the ability to produce, detect, and ultimately control artificial gravitational fields. And would this technology be developed, it could lead to amazing applications like the controlled emission of gravitational waves with large alternative electric currents. Gravity would then cease to be the last of the four fundamental forces not under control by human beings." Jack
