From the freaking paper: "Some bacterial and viral DNA sequences have been found to induce low frequency electromagnetic waves in high aqueous dilutions."
Do someone find that from some other paper? DNA-extraction looks quite easy and I could send and receive signals via USRP and try to detect if there is resonance. It might be an interesting hobby project even, if doomed to fail.
