Update Sci Tech did publish my original message after I complained. 
None of their editors have PhDs in physics. 

This article is misleading on two counts. The actual paper says
In this Letter we show that a set of old conjectures about symmetries in quantum gravity hold within the anti–de Sitter/conformal field theory correspondence. These conjectures are that no global symmetries are possible, that internal gauge symmetries must come with dynamical objects that transform in all irreducible representations, and that internal gauge groups must be compact. These conjectures are not obviously true from a bulk perspective, they are nontrivial consequences of the nonperturbative consistency of the correspondence. More details of and background for these arguments are presented in an accompanying paper."
Therefore, what are excluded are GLOBAL not LOCAL gauge symmetries. This is hardly surprising since it is the case in classical GR. Second, high energy theorists do not properly understand classical GR because they keep calling gravity a "force" rather than a "pseudo force" due to proper acceleration of the detector. To call gravity a "force" in same sense as EM, weak, strong violates Einstein's Equivalence Principle. Classical gravity is the pattern of real-force free timelike geodesics (also light cones). EM, weak, strong charges with invariant rest mass interacting with their relevant fields are pushed off timelike geodesics. Finally, I first formulated a primitive version of ER = EPR in the book "Space-Time and Beyond" E.P. Dutton 1975 see David Kaiser's "How the Hippies Saved Physics. “However, my ER wormholes were traversable with EPR messaging.  Lenny Susskind and I knew each other at Cornell in 1963 and collaborated on his first paper on time and phase quantum operators along with Johnny Glogower.
When I tried to correct them, they censored my post above, while allowing completely off the wall crackpot posts by physics illiterates. The editors clearly have bad judgment.
