Really good explanation in this video. tl;dr: New evidence weakens one of the arguments against Penrose and Hammeroff's ideas of consciousness. We still have no idea if Penrose was correct when he wrote that his educated guess is that consciousness is a quantum phenomenon. But new findings of "room temperature bigger-than-an-atom size quantum effects" are pointing to Hammeroff being right about the microtubules in neurons being capable of conducting such effects. There's no further evidence for quantum computations in neurons or panpsychism (as one explanation of the Penrose-Hammeroff hypothesis seems to require). At any rate, Penrose is someone that still should be taken seriously, whether or not Objective Reduction is a thing (Penrose's solution to the measurement problem).
