There are now questions being raised about the safety and privacy of this new technology. Massachusetts Institute of Technology (MIT) "Technology Review" reports the technology can harm human DNA: "The evidence that terahertz radiation damages biological systems is mixed. "Some studies reported significant genetic damage while others, although similar, showed none," say Boian Alexandrov at the Center for Nonlinear Studies at Los Alamos National Laboratory in New Mexico and a few buddies. Now these guys think they know why.Alexandrov and co have created a model to investigate how THz fields interact with double-stranded DNA and what they've found is remarkable. They say that although the forces generated are tiny, resonant...(Read Full Post)
