Atlanta — Researchers at the Georgia Institute of Technology have made a discovery that could allow scientists to exercise more control over the catalytic activity of gold nanoclusters. The finding – that the dimensionality and structure, and thus the catalytic activity, of gold nanoclusters changes as the thickness of their supporting metal-oxide films is varied – is an important one in the rapidly developing field of nanotechnology. This and further advances in nanocatalysis may lead to lowering the cost of manufacturing materials from plastics to fertilizers. The research appeared in the July 21, 2006 issue of the journal Physical Review Letters www.nanotsunami.com/

Uranium 'pearls' before slime
RICHLAND, Wash.--Since the discovery a little more than a decade ago of bacteria that chemically modify and neutralize toxic metals without apparent harm to themselves, scientists have wondered how on earth these microbes do it.
For Shewanella oneidensis, a microbe that modifies uranium chemistry, the pieces are coming together, and they resemble pearls that measure precisely 5 nanometers across enmeshed in a carpet of slime secreted by the bacteria.
The pearl is uranium dioxide, or uraninite, which moves much less freely in soil than its soluble counterpart, a groundwater-contamination threat at nuclear waste sites.
The U.S. Department of Energy estimates that uranium contaminates more than 2,500 billion liters of groundwater nationwide; over the past decade, the agency has support research into the ability of naturally-occurring microbes that can halt the uranium's underground migration to prevent it from reaching streams used by plants, animals and people...read the wave
the pic to this didn't copy...........http://www.nanotsunami.com/
the second image. i have seen similar growth of this stuff from body particles. i am about 60 miles from hanford!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Moving sounds like a good idea, but where to another planet? www.geocities.com/Area51/Shadowlands/6583/project216. html Be Afraid by Jack Beatty Source: The Atlantic Monthly Group All material copyright © 2000 All rights reserved. April 6, 2000 If the digital revolution is soon to produce what Bill Joy -- one of the world's leading technologists -- fears is a dystopian nightmare, the only hope for humanity may be the end of capitalism as we know it. Try selling that in an election year "This is the first moment in the history of our planet when any species, by its own involuntary actions, has become a danger to itself -- as well as to vast numbers of others." --Carl Sagan In the projectable future robots will replace "biological humans" as economic actors. Unable to compete in the marketplace with their super-intelligent creations, human beings won't be able to afford what they need to live and will "be squeezed out of existence." That is the dystopian vision of robotics. The utopian vision is that humans will attain immortality by "downloading" themselves into the undying electronic being of robots. Genetic engineering will give evil new life, putting the power to loose new plagues on humanity into the hands of terrorists, madmen, and despots. Genetic engineering will soon allow our descendants to end hunger, to create myriad new species with myriad scientific and economic possibilities, to increase our life-span, and to improve our quality of life in dimensions beyond our present means to calculate (in the future we can all be blondes!). Nanotechnology -- manufacturing at a molecular level -- will create plants that will "outcompete real plants," surrounding us with an---- read more at the above link---
