Nano means billionth, so a nanometer is a billionth of a meter. That is clearly very small: on this scale, a human hair is enormous at 100 000 nm across and even red blood cells are thousands of nanometers in diameter. But a DNA molecule, for example, is 2 nm wide. At this level, the properties of materials (electronic, optical, magnetic, etc.) can differ significantly from those at a larger scale, leading to many new possible applications. Nanotechnology is the design and production of materials,devices

Scientists at the University of
California Los Angeles have found a way to create stunningly detailed 3D
reconstructing of platinum nanoparticles at an atomic scale. These are
being used to study tiny structural irregularities called dislocations.

Rumbling down under
Nanotech about to get kicked by unions
Rumbling down under
While nanotechnology is an industry buzzword, it is starting to look as if it will be opposed by the union movement.There are already signs in Oz that nanotechnology is going to be the new spinning jenny.
According to the Sydney Morning Herald, union leader Paul Howes has related nanotechnology to asbestos and called for more research to ease fears the growing use of fine particles could endanger manufacturing workers.

As an increasing number of products which use nanotechnology begin appearing on the market, how can we ensure the workers who make them are protected from the possible risks of working with such minuscule materials?

IPCC asks scientists to assess geo-engineering climate solutions | Environment | guardian.co.uk
IPCC asks scientists to assess geo-engineering climate solutions | Environment | guardian.co.uk:
"Lighter-coloured crops, aerosols in the stratosphere and iron filings in the ocean are among the measures being considered by leading scientists for 'geo-engineering' the Earth's climate, leaked documents from the UN climate science body show.
In a move that suggests the UN and rich countries are despairing of reaching agreement by consensus at global climate talks, the US, British and other western scientists will outline a series of ideas to manipulate the world's climate to reduce carbon emissions. But they accept that even though the ideas could theoretically work, they might equally have unintended and even irreversible consequences.
The papers, leaked from inside the Intergovernmental Panel on Climate Change (IPCC), ahead of a geo-engineering expert group meeting in Lima in Peru next week, show that around 60 scientists will propose or try to assess a range of radical measures, including:
• blasting sulphate aerosols into the stratosphere to reflect sunlight into space;
• depositing massive quantities of iron filings into the oceans;
• bio-engineering crops to be a lighter colour to reflect sunlight; and
• suppressing cirrus clouds.

A Personal Experience with Hair Products
I had a very interesting experience with hair products last week, I wanted to get some kind of hair product for my rather frizzy hair which was burned by the hairdresser last visit and the weather wasn't helping --- no need for details it was just one of those things that you can't get mad about because accidents happen and it wasn't done maliciously --- I went to a little local shop that sells all things "Hair" to ask advise --- the shop person Jessica, was more than helpful and we agreed I wouldn't buy this week I would look through all the "organic" products write down any word in the ingredients list that were unfamiliar -- go home and look them up --- with a little Sherlock Holmes sleuthing and with the help of EWG Database and Wikipedia this is what I discovered --- I looked at Phenoxyethanol, retards microbes, and as its so close to the brain. Coupled with Lactoperoxidase which called a preservative-antibacterial -- so lets go further to see what Wikipedia has to say about this ingredient:
The oxidation of estradiol by lactoperoxidase is a possible source of oxidative stress in breast cancer.[9][10] The ability of lactoperoxidase to propagate a chain reaction leading to oxygen consumption and intracellular hydrogen peroxide accumulation could explain the hydroxyl radical-induced DNA base lesions recently reported in female breast cancer tissue.[9] Lactoperoxidase may be involved in breast carcinogenesis, because of its ability to interact with estrogenic hormones and oxidise them through two one-electron reaction steps.[10] Lactoperoxidase reacts with the phenolic A-ring of estrogens to produce reactive free radicals.[42] In addition, lactoperoxidase may activate carcinogenic aromatic and heterocyclic amines and increase binding levels of activated products to DNA, which suggests a potential role of lactoperoxidase-catalyzed activation of carcinogens in the causation of breast cancer.[43]
People like myself who had a bout with an estrogen based breast tumor this product could be very harmful to people like me.
Now Glucose Oxidase
Glucose oxidase is widely used for the determination of free glucose in body fluids (diagnostics), in vegetal raw material, and in the food industry. It also has many applications in biotechnologies, typically enzyme assays for biochemistry including biosensors in nanotechnologies.[1] It is often extracted from Aspergillus niger.
Now we see a description that includes nanotechnology -- why are they using these items in personal products --- because they can and no one polices these products, even the Environmental Working Groups Cosmetic Database is lacking on this issue. Please read product labels, this affects both men and women ---

The Big Downturn? Nanogeopolitics, ETC Group’s new 68-page report on global governance of nanoscale technologies, is an update of our 2005 Nanogeopolitics survey. In the intervening five years, policymakers – some kicking and screaming – have begun to acknowledge that fast-tracking nanotech has come at a price and that some sort of regulation is needed to deal with at least some of the risks nanoscale technologies pose. But governments and industry, hand in hand, have come too far and invested too much to give up on nanotech’s promise of becoming the strategic platform for global control of manufacturing, food, agriculture and health – a pillar of the 21st century’s “green economy.” This report revisits nano’s geopolitical landscape, providing a current snapshot of global investment, markets, governance and control, including intellectual property.
New Report on Global Governance of Nano-scale Technologies
When activists, social movements and civil society organizations came together in Porto Alegre, Brazil for the first World Social Forum (WSF), governments had just begun pouring money into nano R&D. Now, a decade later, public investment has surpassed US$50 billion and averages $10 billion a year.
Meanwhile, an estimated 50,000 people have come together to learn, debate and strategize at the WSF in Dakar, Senegal. ETC Group brings a new report – The Big Downturn? Nanogeopolitics – to that very large discussion. Executive director Pat Mooney explains why: “An urgent topic in Dakar is the proper governance of emerging technologies and how society can best respond to threats – social, environmental, health – that new technologies may pose. Nanotechnology is a case in point, having been rolled out with virtually no government oversight or public debate.”
Mooney adds, “Our first major report on nano-scale technologies, The Big Down, made its debut at the World Social Forum in Porto Alegre eight years ago. We’ve brought The Big Downturn? to Dakar because nano commercialization and investment are increasing while the regulatory vacuum persists; nano’s risks and impact need fuller discussion.”

The architects of cap and trade included former BP CEO. The sales of stock on the dawn of the BP Gulf disaster were of the oil portions of the company, not the solar/wind portions. Goldman Sachs and BP stand to make trillions through cap and trade. Obama is the top recipient of BP PAC and individual money over the last 20 years.
