“DNA Breathing Dynamics in the Presence of a Terahertz Field” by B. S. Alexandrov, V. Gelev, A. R. Bishop, A. Usheva, K. O. Rasmussen (Submitted on 28 Oct 2009) "Abstract: We consider the influence of a terahertz field on the breathing dynamics of double-stranded DNA. We model the spontaneous formation of spatially localized openings of a damped and driven DNA chain, and find that linear instabilities lead to dynamic dimerization, while true local strand separations require a threshold amplitude mechanism. Based on our results we argue that a specific terahertz radiation exposure may…

Apparently millimeter wave radiation can be ionizing under the right circumstances. That's sort of terrifying. http://arxiv.org/abs/0910.5294

Thanks for bringing the MIT article to my attention. I wouldn't say I referenced the type of radiation, but was just a little less specific. The only source for the article you pointed to (http://arxiv.org/abs/0910.5294) was a model, not an experiment or test. Given the potential for DNA damage, though, it would be silly of me not to agree that more research should be done to see whether this model theory of "resonant effects" have any significant real-world impact.

There is extremely glaring factual mistake in this text. "And guess what wave frequency x-ray backscatter machines use? Hint: THz. http://arxiv.org/abs/0910.5294 Sorry. You missed by a multiplier of 10000-10000000. X-rays go from tens of petahertz to tens of exahertz. X-rays have frequencies way above visible light and terahertz waves have frequencies way below visible light. So this is quite glaring error. Is this intentional to increase doubts about x-ray backscattering or just a honest mistake? Just to clarify for everyone who requires some source for this claim: "X-radiation (composed of…

Ask HN: Please critique backscatter argument

A friend wrote me on the subject of nude scans taken by backscatter x-ray machines: "No worse than a doctor seeing it." After reading several comments on a Hacker News thread, I decided to write a note expressing the implications of the machine and pat-downs. I would appreciate reading your thoughts and ways to improve the content. The original thread: http://news.ycombinator.com/item?id=1848622 -- "No worse than a doctor seeing it." Respectfully, I disagree. * You can screen your doctor for trustworthiness. * You can choose to visit a doctor of a gender you prefer. * Doctors are bound by the…
