I have recently read a post by parapsychologist Dean Radin where he says that the evidence for quantum coherence in living systems at room temperature. He says this recently because another experiment has been done that shows quantum coherence continues even at room temperature so their is some form of quantum entanglement in living systems. This conflicts with long held dogma that it simply is not possible to have quantum effects in living systems. This new experiment is published in the science journal called nature. Rather or not this is the mechanism for psi is an open question.
