A quantitative explanation of EM coherence domains in liquid with DNA I've been looking with interest at a recent biology paper claiming that DNA molecules give off electromagnetic signals which can cause the same types of molecules to be reconstructed at a remote location. The Slashdot crowd seems to think the idea is pretty ridiculous, and I'm inclined to agree, but I still think it's worth digging into some of the physics they cite.
A large part of the theoretical argument in the paper relies on what they call coherence domains. As far as I can tell, they're talking about a relatively large region of liquid (in this case water) in which all the molecules are in resonance with an oscillating electromagnetic field which is confined by the boundary of the region itself. I don't think I really grok that description, and a Google search for further information turned up nothing relevant. I'd like to see some of the math that backs this up. So can anyone provide a more mathematical explanation of how these coherence domains are able to exist?
(I'm assuming the whole idea is not totally bogus :-P)
 A: To emit a radio wave of any sort which sticks out above ordinary thermal radiation, you need an energy source which is not thermal. Such an energy source is not available to DNA molecules in dilute solutions. If there is some cellular machinery which is responsible for emitting low frequency EM waves, it would require some energy source and would be sensitive to dilution. The idea that DNA emits radio is a perpetual motion machine of the second kind.
The electromagnetic signals are in my opinion amplified thermal noise, and the "signal" stands out because the water with the DNA in it that he uses is slightly warmer.
A: Well I cannot give the mathematics; however (and it is an "idea" assuming it is not ridiculous) I would like to point out that water is a polar molecule, and therefore has to give off (an incredibly small) magnetic field. If your cells could fluctuate the magnetic fields of all the water in that region, then they could give off a signal... However that's just a thought and, truth be told, probably not likely. 
A: You could check the works of Emilio del Giudice, Giuliano Praparata et al. The second one in particular is been involved in the study of coherence effects in quantum field theory, in particular in quantum chromo dynamics and quantum electrodynamics. In this article
http://www.worldscientific.com/doi/abs/10.1142/S0217979295000744?prevSearch=preparata+del+giudice&searchHistoryKey=
they propose an explanation of the strange behaviour of water just based on such coherence effects. Maybe here you will find what you're searching for.
