'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 effects allow THz waves to unzip double-stranded DNA, creating bubbles in the double strand that could significantly interfere with processes such as gene expression and DNA replication. That's a jaw dropping conclusion.'

This radiation is all around us. Terahertz is far infrared radiation or heat. Heat causes DNA to unzip its the function that enables cell division. But i guess its what happens if you read a paper on DNA by a couple of computer programmers! Its a perfectly natural process. No scanners that are in airports use terahertz either they are mm wave. 1000 times lower in frequency and a radio wave rather than terahertz which is light. The worlds awash with radiation in the range 1 to 10 THz its heat!
