>True Spooky: Terahertz Waves Tear Apart DNA?

… 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.

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.

>The True Spooky: Untold details of 9/11

>Halloween Scare:

The (hopefully wrong) impression a person could get from watching a couple of YouTube videos (below), from seemingly different sources, is that there were art students (spies) with tons of bombs and full access to the WTC living in it (for months?) before the attacks of 9/11.

Scary stuff. They had tons of boxes, supposedly with bombs in them.  Also, art students in white vans, according to real news sources, were arrested by the FBI on 9/11.  According to the tape of police on the day of the attack, they  exploded one van and they were arrested with another van full of explosives.

Those in custody failed polygraph tests and, although the story started to be told by Fox News, we never heard anything else about this or the remote controlled planes mentioned on police radio…

because the evidence is still classified.

Gulp. What could be more spooky?

No one has posted any comments debunking these claims yet… Anyone from Popular Mechanics care to comment?

>Are you getting what you signed up for from Comcast?

>Yesterday I was given a low price of $34/mo for the 16MB Comcast “Blast Package” for 9 months, then $52/mo after that… by a rep at a Comcast  service center.  I wrote it down and confirmed what I was getting as I was standing at the counter. Today they hooked it up. I had 11 MB.

I called Comcast to figure out what was wrong, and my speed cut back as I was talking to the rep to 6 MB/sec.  The rep claimed not to have done anything, but for a good 10 minutes before I called I was getting 11 to 12 MB download speeds, after calling, I had only 5 MB. After I hung up, I was getting only 3 to 5 MB/sec.  I thought perhaps my cell phone was causing interference slowing down my internet connection…

Keep in mind that these tests vary over time depending on network traffic to the particular server you are testing against. But the change in speed happened to the same server.

Test your speed here:

• http://www.dslreports.com/speedtest?flash=1
• http://www.speedtest.net/
• http://www.speakeasy.net/speedtest/
• http://www.bandwidthplace.com/

The rep on the phone told me I  signed up for the 6 MB/sec package. Bull feathers. I have the paper right in front of me signed by “BBI” and it says 16MB. How was I getting 11 MB/sec with a 6MB/sec package?

The phone rep claims that I have to go in in person to get what I signed up for. Yes, I will. And if I don’t get what I was promised, I will cancel my service.

Now it is Friday at 5 PM and they are closed. Check your speed.
PS. Happy Halloween! No more posts till Sunday night or so.

PPS. After posting this, my speed went up to 8MB/sec.  What the heck? Are these tests accurate?

>BP fined $87m for Texas explosion

>

BP has been fined a record $87m (£53m) for failing to correct safety hazards at its Texas City refinery in the US.

An explosion in 2005 at the Texas plant killed 15 people and injured 180 more.

The Occupational Safety and Health Administration (OSHA) cited 270 violations at the oil refinery, a US Labor Department official said.

BP said it believed it was in “full compliance” with a 2005 settlement agreement with OSHA and would work with the agency to resolve the issue.

The $87m fine is the largest in OSHA’s history.

In 2005, BP paid a $21.3m fine to OSHA and entered into a four-year agreement to repair hazards at the Texas City refinery, which is the third largest in the US.

The latest fine follows a six-month inspection into whether BP had complied with that agreement. …

The safety violations found “could lead to another catastrophe”, US Labor Secretary Hilda Solis said.

“An $87m fine won’t restore those lives [lost in the 2005 explosion], but we can’t let this happen again. Workplace safety is more than a slogan. It’s the law,” Ms Solis said.

BP said in a statement: “While we strongly disagree with [OSHA’s] conclusions, we will continue to work with the agency to resolve our differences.”

The firm will now have 15 days to either agree to pay the fine and take corrective action, or to contest the penalty through a hearing process.

BP was fined $50m by the Department of Justice in 2007 to settle criminal charges stemming from the Texas explosion.

Lawyers for the victims’ families said this was not enough.

The company has also paid more than $2bn to settle civil lawsuits and says it has invested more than $1 billion to repair safety problems at Texas City. …

>3,000 images combine for Milky Way portrait

>

To combine these images, a simple cutting and pasting job would not suffice. Each photograph is a two-dimensional projection of the celestial sphere. As such, each one contains distortions, in much the same way that flat maps of the round Earth are distorted. In order for the images to fit together seamlessly, those distortions had to be accounted for. To do that, Mellinger used a mathematical model — and hundreds of hours in front of a computer.

Another problem he had to deal with was the differing background light in each photograph.

“Due to artificial light pollution, natural air glow, as well as sunlight scattered by dust in our solar system, it is virtually impossible to take a wide-field astronomical photograph that has a perfectly uniform background,” Mellinger said.

To fix this, Mellinger used data from the Pioneer 10 and 11 space probes. The data allowed him to distinguish star light from unwanted background light. He could then edit out the varying background light in each photograph and fit them together so that they wouldn’t look patchy.
