The following is an excerpt.
Short yet powerful bursts of terahertz radiation can damage DNA and also increase the production of proteins that help the cells to repair this damage. That is the conclusion of physicists and biologists in Canada, who have studied how the electromagnetic radiation interacts with human skin cells. The discovery could lead to the development of new medical therapies that make use of terahertz radiation.
