Instead of diffusing into the solution as they escape the needle, the viruses cling together, forming a wispy white fiber that's several centimeters long and about as strong as a strand of nylon. A graduate student, Chung-Yi Chiang, fishes it out with a pair of tweezers. Then he holds it up to an ultraviolet light, and the fiber begins to glow bright red. In producing this novel fiber, the researchers have demonstrated a completely new way of making nanomaterials, one that uses viruses as microscopic building blocks. Belcher, a professor of materials science and biological engineering at MIT, says the approach has two main advantages. First, in high concentrations the viruses tend to organize themselves, lining up side by side to form an orderly pattern. Second, the viruses can be genetically engineered to bind to and organize inorganic materials such as those used in battery electrodes, transistors, and solar cells. The programmed viruses coat themselves with the materials and then, by aligning with other viruses, assemble into crystalline structures useful for making high-performance devices. But the approach is not just an alternative way to make familiar devices; it could also be the impetus for developing entirely new ones. In past work, Belcher has created virus-based thin films for rechargeable batteries. Now that she can spin viruses into fibers, she envisions threadlike batteries and other electronic devices that can be woven directly into clothing. "It's not really analogous to anything that's done now," she says. "It's about giving totally new kinds of functionalities to fibers." The virus-based fibers have caught the attention of U.S. Army researchers. They hope to incorporate future versions of the fibers into uniforms, weaving them into the fabric along with other supporting materials. The resulting fabrics could have an array of advanced capabilities. Clothing made with them could sense agents of chemical and biological warfare; it might also store energy from the sun and power portable electronic devices, such as night-vision gear. Charlene Mello, a macromolecular scientist at the Natick Soldier Research, Development, and Engineering Center in Natick, MA, says that while such uniforms will probably take decades to develop, Belcher's work has paved the way for them. Spinning Viruses Belcher uses different procedures to make different kinds of virus fibers. To make the glowing fibers, she first used conventional genetic-engineering methods to modify the virus DNA so that one of the proteins that make up the body of the virus has extra copies of a specific amino acid at one end. At the same time, the researchers synthesized quantum dots (semiconductor nanocrystals that emit intense light at precisely tuned wavelengths) with surface amine groups that bind to the overproduced amino acid. The result: hundreds of quantum dots glommed onto each virus, which combined with similar viral particles to form a fiber that emits light. Often, however, it's not obvious how to make a virus bind to specific inorganic materials, such as gold particles. In these situations, Belcher uses a method sometimes called "directed evolution," which allows her to quickly modify viruses to work with a range of materials.

Is it spiritual? is it science? is it nano? www.news.com.au/story/0,23599,22634351-2,00.html?from=mostpop Man levitates outside the White HouseBy staff writers October 23, 2007 12:39pm Article from: Font size: + - Send this article: Print Email DUTCH magician Ramana has been doing his best to freak out American people by levitating in Times Square and in front of the White House. The illusionist, real name Wouter Bijdendijk, hovered several feet above the pavement with apparent ease. His only "prop" was a stick that he held with his left hand. A household name in his native Netherlands, Ramana has performed for Queen Beatrix and has been honoured in India with the Golden Cloth award, the highest cultural honour ever given to a westerner, metro.co.uk reported. "This is an art," he said. "And in India, they see it also as a science. I hope I make people wonder," Ramana said. Ramana's repertoire also includes "flying" up to 10 metres above ground, mind reading and other forms of Indian street trickery.

she might wont to be careful the side view of her face looks a little like she has the beginning stages of morgellons!And I dont wish this to my worst enemy!these people are playing with fire!

Can we list the number of 'things' these have become the delivery medium for?
From viruses carry/create viruses and clothing... bizarre.

"quickly modify" and 'steer the evolution' seem to be a key point to these things - change a micro perameter and the thing develops itself on a macro level.

There ya go. if this is top down can be switched off, but, if it is bottom, it can't

I think I posted once about how they plan to have nano created 'human like' people by the year 2050...and they remarked that they will not only have a personality, but that you will be able to have sex with them!! YUCK! Who the heck would WANT to? And the tiny 'Bucky ball' like things, I posted about how they talked about using them for a newer form of bio warfare like weapons that are invisible, but will be preprogrammed to find 'the enemy', and most likely be re;eased into the air, breathed in, and they will 'most likely' go to the brain to begin to destroy 'the enemy'... Ever read up on research they did some years ago? ( I read from a persons post on here it was actually KAISER that did that research)...But, man has the technology to tell, by a single drop of blood, if you are most likely to be a 'productive' person, what type of JOB you would have, whether there is drug abuse in your family history, mental illness and on and on, etc... hmmm.... And hey, all the rest of THIS is info I got from Scientific Web Sites about the nano tech stuff, not a whacked out loony toon site...

From the genome able to make anything you want, along with inorganic substances.
