What DNA makes possible


DNA is a big molecule which consists of several building rocks like the Nucleosides and code protein. GM changes or influences DNA. One can transfer parts of DNA molecule from one cell to every other cell, no matter what kind of living organism it is.

....Gosline realised that the different mechanical properties could be accounted for by the silk proteins' amino acid composition. According to Gosline, proline amino acids are famed for breaking up the organised three-dimensional structures that protein chains fold into, so protein structures with high proline content would be poorly organised in comparison to proteins with little or no proline. Araneus silk contains 16% proline, found mostly in linker regions between the protein's crystalline structures, which would make the linkers flexible and randomly arranged.

WELL? Interesting... hmmm? As I stated earlier, everything WE THINK we've seen, so far - can be explained by things found in nature.

We're in the infancy of discovering what Morgellons really is. Until we know more factual information, we won't know for sure... until then.

I have noticed a pattern to all of these new nano-inventions... have you noticed how their first few sentences in their articles most always start with justifying their creations by how it will benefit the betterment of medicine and how it will advance our health technology in the future? Playing on the human psychological aspect of betterment of our health to promote their nanonightmaremachines, I've seen it quite a bit. As in Kat's example above, here's a different article:

Kammy -
Yes, most of them do...but more and more I am seeing articles warning of the possible dangers of it.
There is a Bill in Congress asking for oversight into the safety of nanotechnology. I'll post a few of these as time goes on if people want to see them.
I don't know...all this concern for the planet (yesterday was "Earth Day")....it's great, but I can't help feeling that it is too little too late, especially as they go off in this new direction. The technology that they hope will save the planet may end up facilitating it's demise.
2012, here we come...

Here's a new one (re:above):

Nanoparticles for water and desalination - how safe are they?

Nanoparticles for water and desalination - how safe are they?



The potential dangers from the use of engineered nanoparticles, such as nanotubes, metal oxides or nanodots, some of which form the basis of new solutions for desalination and water treatment, are outlined in a new European Union publication.

The Science for Environment Policy Newsletter, produced by the Directorate General for the Environment, published a special edition on 22 April 2009 on Nanomaterials. In the forward to the newsletter, Prof Kenneth Donaldson, Professor of Respiratory Toxicology, ELEGI Colt Laboratory, University of Edinburgh, states, "The potential impacts of manufactured nanoparticles on health are of particular concern."

Under a heading "Are carbon nanotubes the new asbestos?", the newsletter refers to Polish research conducted on mice, which indicated that a specific type of carbon nanotube does have asbestos-like effects, although further research was needed to assess whether this was also the case for humans.

Carbon nanotubes are cylindrical carbon molecules, typically a few nanometres in diameter. They are very strong, conduct heat efficiently and have unique electrical properties that make them potentially useful in many fields.

Two examples of nanotechnology use with water treatment membranes are: nanostructured filters, where either carbon nanotubes or nanocapillary arrays provide the basis for nanofiltration; and nanoreactive membranes, where functionalized nanoparticles aid the filtration process.

The Polish researchers expressed concerns about the potential health hazards of nanotubes due to their superficial resemblance to asbestos. Exposure to asbestos causes a specific type of cancer called mesothelioma, and there are concerns that nanotubes may also cause this cancer.

Their results revealed that only long multi-walled carbon nanotubes show asbestos-like behaviour. However, the authors point out that their test was specific for fibres and that nanocarbon in the form of particles could be harmful in ways that are not addressed in their study.

"This flags up the importance of choosing the correct method of evaluating toxicity," warns the EU newsletter. It goes on to look at a Finnish study, which has found that two commonly manufactured nanomaterials can damage human DNA, highlighting the need to evaluate the risks they might pose and design appropriate safety tests.

The scientists treated cultured human lung cells with nanotubes and graphite nanofibres, and observed changes in the DNA. Both the nanomaterials caused DNA damage in the cultured cells, and there was a direct link between the dose of carbon nanotubes and the amount of damage.

Other articles in the newsletter highlight research on effects on the environment from engineered nanoparticles and how they could be released into it. Prof Donaldson concludes:

"The issues surrounding engineered nanomaterials are recognised as important by the European Commission. The nanotechnology action plan (2005-2009) has provided strong support for research in this area.

"However, more research is needed, especially in the areas of food and exposure assessment. To allow nanotechnology to develop to its full potential, research into the risks of nanotechnology must continue alongside development of nanotechnology itself to inform future policy and maintain European industrial competitiveness."

Rice University scientists have captured the first optical images of carbon nanotubes inside a living organism. The research appears in the September 2007 issue of Nano Letters. The researchers fed carbon nanotubes to newly hatched fruit flies. Using a laser, they excited a fluorescent glow from the nanotubes and took pictures of the near-infrared glow with a custom microscope. The researchers hope the technique will be useful in finding new ways to diagnose disease.

What is Asbestos?

Asbestos is a naturally occurring mineral fiber that has been used in more than 3,000 different construction materials and manufactured products. It is commonly found in heating system insulation, decorative spray-on ceiling treatments, vinyl flooring, cement shake siding and a variety of additional materials. Some asbestos-containing materials were still being installed into the late 1980s.
All types of asbestos tend to break into very tiny fibers. These individual fibers are so small that many must be identified using a microscope. In fact, some individual fibers may be up to 700 times smaller than a human hair. Because asbestos fibers are so small, once released into the air, they may stay suspended there for hours or even days.
Asbestos fibers are also virtually indestructible. They are resistant to chemicals and heat, and they are very stable in the environment. They do not evaporate into air or dissolve in water, and they are not broken down over time. Asbestos is probably the best insulator known to man.
Usually asbestos is mixed with other materials to actually form the products. Floor tiles, for example, may contain only a small percentage of asbestos.The asbestos content of different materials varies according to the product and how it is used. Among those materials with higher concentrations of asbestos are insulation products on heating Systems and the backing on sheet vinyl flooring. However, an uncontrolled disturbance of any asbestos-containing material in any concentration may be dangerous to your health!

Great find, Kat!
Did you see the post about carbon nanotubes causing mesothelioma, just as asbestos does?

Rising Cases of Mesothelioma in the UK

In the United States alone, the number of new mesothelioma cases each year is between 3,000 and 4,000. These numbers are still rising and are not expected to peak until 2025. This translates to thousands of Americans each year developing mesothelioma due to exposure to asbestos. A great number of these victims do not know why they have developed mesothelioma.

Mesothelioma Medical Information

Roughly 80% of cases are believed to derive from occupational or paraoccupational exposure to primary asbestos fiber types...
The remaining 20% of cases have no clear-cut occupational cause and are believed to be related to etiologic factors, including contact with nonindustrial fibers such as erionite and exposure to simian virus 40 (SV40), a DNA tumor virus affecting Asian macaques that contaminated poliovirus vaccine stocks used in the late 1950s/early 1960s.

OR MAYBE IT IS NANOTECHNOLOGY......SS

Do you mean this one, Sadsack?

Yes Mesothelioma is a VERY serious cancer form...

..We have developed uniform core/shell nanoparticles, consisting of a silica layer coating and pigments or magnetite core, using a water-in-oil microemulsion method. The nanoparticles are highly luminescent and photostable with the size ranging from 5 nm to 400 nm. Bioconjugation of these silica nanoparticles adds unique biofunctions with various molecules such as enzymes, antibodies, and DNA molecules. Significant advantages have been shown in using bioconjugated nanoparticles for biosensing and bioimaging, such as cell staining, DNA detection and separation, rapid single bacterium detection, and biotechnological application in DNA protection.

WOW! Kat - this looks very significant! (Will you put this info up in the Think Tank?)

I was just about to say, that everything that's in-between my packing tape is in a 'freeze-dried' or dissecated state. I'm guessing that all I need to do is remove these particles out of this tape and add a little moisture or drop them in a Petri Dish and they will start to grow? And, can probably get the same results a year from now? And, who knows how long?

I just saw a 'black speck' that is totally microscopically, unreconizable in this 'freeze dried' state as compared to when you view it a day from now in a Petri Dish that it resembles like A. niger.

Everything is in a protective crystal coating.

*Kat - we're getting a "Session Cookie Error" on that link above. I suppose we have to Register to use that site? I just Registered... and can probably do a search on "uniform core/shell nanoparticles" to find the article?

Well... darn, it looks we've been bio-teched and now nano-teched? It looks like the protective coating, we're seeing and I'm referring to is made of a silica coating is made of nanoparticles, according to this science article above of known technology?

Abstract
Amino-modified silica nanoparticles (FSNPs) doped with fluorescein isothiocyanate (FITC) were synthesized by using an aqueous core of reverse-micelle microemulsion as the nanoreactor in an easy one-pot method. Due to the FITC conjugating with (3-aminopropyl)triethoxysilane (APTS), the nanoparticles prevent the FITC from leaching from the silica matrix when immersed in aqueous solution. SEM, FTIR, fluorescence lifetime, a photobleaching experiment and synchronous fluorescence spectra were used to characterize the FSNPs. The synchronous fluorescence signal of FSNPs was enhanced when trace amounts of -globulin (-G) were added. Under the optimal experimental conditions, the enhanced fluorescence intensity (F) was linear with the concentration of -G (c) in the range 0.3-4.8 µg/mL, with a detection limit of 0.04 µg/mL. The proposed method is simple, sensitive for the determination of trace amounts of -G and used to determine the content of -G in synthetic samples with satisfactory results.
