How Terahertz Waves Tear Apart DNA

A new model of the way the THz waves interact with DNA explains how the damage is done and why evidence has been so hard to gather

Great things are expected of terahertz waves, the radiation that fills the slot in the electromagnetic spectrum between microwaves and the infrared. Terahertz waves pass through non-conducting materials such as clothes , paper, wood and brick and so cameras sensitive to them can peer inside envelopes, into living rooms and "frisk" people at distance.

Terahertz Radioation

The way terahertz waves are absorbed and emitted can also be used to determine the chemical composition of a material. And even though they don't travel far inside the body, there is great hope that the waves can be used to spot tumours near the surface of the skin.

With all that potential, it's no wonder that research on terahertz waves has exploded in the last ten years or so.

But what of the health effects of terahertz waves? At first glance, it's easy to dismiss any notion that they can be damaging. Terahertz photons are not energetic enough to break chemical bonds or ionise atoms or molecules, the chief reasons why higher energy photons such as x-rays and UV rays are so bad for us. But could there be another mechanism at work?

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 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.

And it also explains why the evidence has been so hard to garner. Ordinary resonant effects are not powerful enough to do do this kind of damage but nonlinear resonances can. These nonlinear instabilities are much less likely to form which explains why the character of THz genotoxic effects are probabilistic rather than deterministic, say the team.

This should set the cat among the pigeons. Of course, terahertz waves are a natural part of environment, just like visible and infrared light. But a new generation of cameras are set to appear that not only record terahertz waves but also bombard us with them. And if our exposure is set to increase, the question that urgently needs answering is what level of terahertz exposure is safe.

I wouldn’t trust anything Simon Treselyan has to say. He is a thief and a Con artist who fled Australia owing money that he refuses to pay back. He is trying to build his public profile up in the USA at the moment so i expect his past will always come back to haunt him.

your problem eugene is that you consider this pathetic dog and pony show a “news” service. if you paid good money to listen to the tripe spewed out my the insipid fenton, then let that be a lesson to you.
tnr has no reputation, except a bad one, and for good reason. they are pathetic liars. do yourself a favour and never come back smile

I think my comment was a reasonable one. I have no idea what’s going on, but whatever it is, it is certainly not doing TNR’s reputation much good. 45 minutes of “news” in almost six weeks, with no explanation. This in no way to treat your listening audience (subscribers and others) or to build support and a good reputation.

“In today’s show we break down the core issues behind the conviction of David Hicks, and link the whole thing back to the grand deception of 9/11, without which, none of this would have occurred.”

and yet hereward continues to perpetuate the lies of 9/11 by claiming a 757 hit the pentagon with absolutely zero evidence to back it up and a plethora of evidence that shows his claims to be impossible.

spare us your condescending enlightenment and stop lying.

The comment by Eugene above is most unhelpful to say the least

, “you know Shawn, we might not be able to save your house, what do you think we should do?”...wouldn’t you find that a liltte bit strange? Assuming of course that you, like Mr. Silverstein, had absolutely no affiliation with or expertise in fighting fires? Or would you proceed to direct the fire chief, over then phone mind you, on whether to proceed with fighting it or pull the fire chiefs men out?  Larry Silverstein, Jewish landlord, financier, and part time psychic fireman safety coordinator for NYFD Secondarily, and less relevant, I have no demolition experience beyond home repair, but I do have a background in linguistics (thanks Noam!) and the only time an English speaking person refers to a human being or group of human beings as “it” tends to be right before they eat them. Perhaps Silverstein is a psychopath, I know liltte else about him so I can’t say, but but violent psychos refer to their victims as objects to dehumanize the experience of killing them. But I don;t think that’s what Larry meant. On that note, as I’ve said before, find me one other example of anyone on the scene on 9/11, or ANY TIME SINCE that has referred to a firefighter or group/contingent/unit of firefighters as “IT”. Not “them”, “they” “him”, “we”, “our”, “us”, but “it”. You can’t find one.  Because most people aren’t psychotic, amen for that.

Herewood,
If you want financial support on a regular basis, you need to regularly present news casts. There has been nothing for almost a month. I have been listening to TNR for its inception, and it has never been as scatty. In six weeks you have only presented an hour of reporting, 15 minutes of which is punctuated by useless advertisements which have little or no relevance to Australians. I hope you can lift your game or I fear this once brilliant show will be destined for the scrapheap.

josh just cant help pretend he is some sort of intellectual wannabe by regurgitating the retarded bile of fecktards everywhere..
boring josh.. unqualified anonymous josh who speaks on the authority of a half shitted pair of underpants..

feck off ya useless squib

Yes, fascinating.  However, I would be more inclined to resort to massive vitamin C (sodium ascorbate) used successfully by Dr Brighthope in cancer, both as a painkiller and healing.  He also used successfully vit C to heal AIDS. 

Well, when i still lived in formerCzechoslovakia (during the regime of the Communist party) we believed in the USA and capitalism.  There was a (Russian) joke about it: two comrades travel to the West and talk to each other, “Capitalism is decaying but the smell is wonderful”; and agreed that when they come back home they will talk cryptically about the situation in the west: when talking about good things they will say “like in a film” and when talking about bad things “like at home”.

Well, these days I must say that the situation in the West is “like at home” and the capitalism is decaying but the smell is not so wonderful.
