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

2011-05-26T10:29:00.001-04:00

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

2011-05-26T07:53:00.000-04:00

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.”

Secretive food firms risk public backlash, Lords warn

The secretive attitude of food companies towards nanotechnology research risks starting a consumer backlash against products that could improve health and reduce waste, a parliamentary inquiry has found.
Nanomaterials that are 800 times finer than a human hair have the potential to deliver foods that are very low in fat and salt and packaging that changes colour when food is spoiled because of the strange properties of molecules at such a small scale. Their development, however, has also raised safety concerns because their effects on humans are poorly understood.

Commission starts public dialogue on nanotechnologies – tapping economic and environmental potential through safe products

Nanotechnologies have enormous potential benefits for manufacturers, consumers, employees, patients and the environment. They will bring more energy and resource efficient processes, improve computer memories and processors and could usher in a new age of customized pharmaceuticals and medical procedures.

While current EU legislation covers in principle the challenges for health, safety and environment with regards to nanomaterials, there is further need for research and international cooperation.

As more and more products involving nanomaterials are reaching the market, the European Commission will start a consultation with stakeholders and Member States in order to increase knowledge and awareness about the potential of nanotechnologies and to continue to ensure an adequate protection of nature, environment and health.

Problematic new findings regarding toxicity of silver nanoparticles
(Nanowerk Spotlight) Engineered nanoparticles are rapidly becoming a part of our daily life in the form of cosmetics, food packaging, drug delivery systems, therapeutics, biosensors, etc. A number of commercial products such as wound dressing, detergents or antimicrobial coatings are already in the market. Although little is known about their bio distribution and bio activity, especially silver nanoparticles are extensively used for all kinds of antimicrobial applications. Ultimately, these nanoparticles end up in the environment during waste disposal. Largely due to a scarcity of data on the toxicity, intracellular distribution and fate of silver ions and nanoparticles inside an organism, regulatory bodies so far have not felt the need to regulate the use of such materials in commercial products or disposal of such products.
In a major reversal, although more of a symbolic gesture, earlier last year the U.S. EPA has determined that clothes washing machines that use silver ions as a disinfectant will have to be registered as a pesticide (The first federal restrictions on nanotechnology could be coming soon). The lack of regulation has even led to a dramatic demand from activist groups to completely ban the sale of nanosilver products (Groups file legal action for EPA to stop sale of 200+ nanosilver products).

Explaining How Depleted Uranium Is Killing

Civilians, Soldiers, Land

Nano-particles pinpointed

By Christopher Bollyn

Depleted uranium weapons, and the untold misery they wreak on mankind, are taboo subjects in the mainstream media. This exclusive report should break the media embargo imposed on the American people.

Despite being a grossly under-reported subject in the mainstream, there is intense public interest in depleted uranium (DU) and the damage it inflicts on humankind and the environment.

While American Free Press is actively investigating DU weapons and how they contribute to Gulf War Syndrome, the corporate-controlled press ignores the illegal use of DU and its long-lasting effects on the health of veterans and the public.

In August 2004 American Free Press published a ground-breaking four-part series on DU weapons and the long-term health risks they pose to soldiers and civilians alike. Information provided to AFP by experts and scientists, some of it published for the first time in this paper, has increased public awareness of how exposure to small particles of DU can severely affect human health.

Leuren Moret, a Berkeley-based geo-scientist with expertise in atmospheric dust, corresponds with AFP on DU issues. Recently Moret provided a copy of her letters to a British radiation biologist, Dr. Chris Busby, about how nanometer size particles—less than one-tenth of a micron and smaller—of DU once inhaled or absorbed into the body, can cause long-term damage to one’s health.

Busby is one of the founders of Green Audit, a British organization that monitors companies “whose activities might threaten the environment and health of citizens.”

Moret’s writings were meant to assist Busby in a legal case being heard in the High Court in London where a former defense worker, Richard David, 49, is suing Normal Air Garrett, Ltd., an aircraft parts company now owned by Honeywell Aerospace, claiming exposure to DU on the job has made his life a “living hell.”

David worked as a component fitter on fighter planes and bombers but had to quit due to health problems. He says he developed a cough within weeks of starting work.

Today, David suffers from a variety of symptoms like those known as Gulf War Syndrome, including respiratory and kidney problems, bowel conditions and painful joints. Medical tests reveal mutations to his DNA and damage to his chromosomes, which, he says, could only have been caused by ionizing radiation. He has also been diagnosed with a terminal lung condition.

Honeywell denies DU was ever used at the plant in Yeovil, Somerset, where David worked for 10 years until 1995. David claims that DU’s existence at the plant was denied because it is an official secret.

David has asked the High Court for more time to gather evidence. The hearing is due to resume in April. “I don’t have any legal representation,” David said, “so I am representing myself. It is a real David versus Goliath case.

“I am confident I will win. I hope to set a precedent for other cases of people who have suffered from the effects of depleted uranium,” he said.

Moret’s letters on the particle effect of DU is based on research done by Marion Fulk, a nuclear physical chemist and former scientist with the Manhattan Project and the National Laboratory at Livermore, Calif. Fulk, who has developed a “particle theory” about how DU nano-particles affect human DNA, donates his time and expertise to help bring information about DU to the public.

Asked about Fulk’s particle theory, Busby said it is “quite sound.”

“DU is much more dangerous than they say,” Busby added. “I’ve always said that it contributes significantly to Gulf War Syndrome.”

When Moret’s correspondence to Dr. Busby was posted on the Internet over the New Year’s holiday under the title “How Depleted Uranium Weapons Are Killing Our Troops,” some 6,000 people read the letter in the first two days. The following Monday, a producer from BBC’s Panorama program contacted Moret to arrange an interview.

If the BBC follows up with an investigation on the health effects of DU, it may be hard for the U.S. media to maintain their cover-up. More than 500,000 “Gulf War Era” vets currently receive disability compensation, many of them for a variety of symptoms generally referred to as Gulf War Syndrome. Experts blame DU for many of these symptoms.

“The numbers are overwhelming, but the potential horrors only get worse,” Robert C. Koehler of the Chicago-based Tribune Media Services wrote in an article about DU weapons entitled “Silent Genocide.”

“DU dust does more than wreak havoc on the immune systems of those who breathe it or touch it; the substance also alters one’s genetic code,” Koehler wrote. “The Pentagon’s response to such charges is denial, denial, denial. And the American media is its moral co-conspirator.”

U.S. GOVERNMENT KNOWS

The U.S. government has known for at least 20 years that DU weapons produce clouds of poison gas on impact. These clouds of aerosolized DU are laden with billions of toxic sub-micron sized particles. A 1984 Department of Energy conference on nuclear airborne waste reported that tests of DU anti-tank missiles showed that at least 31 percent of the mass of a DU penetrator is converted to nano-particles on impact. In larger bombs the percentage of aerosolized DU increases to nearly 100 percent, Fulk told AFP.

DU is harmful in three ways, according to Fulk: “Chemical toxicity, radiological toxicity and particle toxicity.”

Particles in the nano-meter (one billionth of a meter) range are a “new breed of cat,” Moret wrote. Because the size of the nano-particles allows them to pass freely throughout the organism and into the nucleus of its cells, exposure to nano-particles causes different symptoms than exposure to larger particles of the same substance.

Internalized DU particles, Fulk said, act as “a non-specific catalyst” in both “nuclear and non-nuclear” ways. This means that the uranium particle can affect human DNA and RNA because of both its chemical and radiological properties. This is why internalized DU particles cause “many, many diseases,” Fulk said.

Asked if this is how DU causes severe birth defects, Fulk said, “Yes.”

MILITARY AWARE

The military is aware of DU’s harmful effects on the human genetic code. A 2001 study of DU’s effect on DNA done by Dr. Alexandra C. Miller for the Armed Forces Radiobiology Research Institute in Bethesda, Md., indicates that DU’s chemical instability causes 1 million times more genetic damage than would be expected from its radiation effect alone, Moret wrote.

Dr. Miller requested that questions be sent in writing and copied to a military spokesman. She did tell AFP that it should be noted that her studies showing that DU is “neoplastically transforming and genotoxic” are based on in vitro cellular research.

Studies have shown that inhaled nano-particles are far more toxic than micro-sized particles of the same basic chemical composition. British toxicopathologist Vyvyan Howard has reported that the increased toxicity of the nano-particle is due to its size.

For example, when mice were exposed to virus-size particles of Teflon (0.13 microns) in a University of Rochester study, there were no ill effects. But when mice were exposed to nano-particles of Teflon for 15 minutes, nearly all the mice died within 4 hours.

“Exposure pathways for depleted uranium can be through the skin, by inhalation, and ingestion,” Moret wrote. “Nano-particles have high mobility and can easily enter the body. Inhalation of nano-particles of depleted uranium is the most hazardous exposure, because the particles pass through the lung-blood barrier directly into the blood.

“When inhaled through the nose, nano-particles can cross the olfactory bulb directly into the brain through the blood brain barrier, where they migrate all through the brain,” she wrote. “Many Gulf era soldiers exposed to depleted uranium have been diagnosed with brain tumors, brain damage and impaired thought processes. Uranium can interfere with the mitochondria, which provide energy for the nerve processes, and transmittal of the nerve signal across synapses in the brain.

“Damage to the mitochondria, which provide all energy to the cells and nerves, can cause chronic fatigue syndrome, Lou Gehrig’s disease, Parkinson’s disease and Hodgkin’s disease.”

Small may not be beautiful

Imagine a low-fat ice-cream that tastes just as creamy as an unhealthier, full-fat version. Or a colourless drink that bursts into the flavour of your choosing at the flick of a microwave switch. Or intelligent food packaging that detects if the contents are beginning to spoil, changes colour to alert you, and then releases a preservative.

These are some of the promises of nanotechnology, a revolutionary area of research at the atomic or molecular scale of matter. Nanotechnology is expected to have a huge impact on many aspects of our lives, including medicine and the environment, with the development of materials and devices that can monitor blood, detect environmental pollutants and store energy better.

But one of its most immediate effects will be on our food. An estimated 200 companies worldwide are conducting research using nanotechnology to develop foods with new tastes and textures, as well as to improve packaging and enhance nutrient absorption.

Some products containing nano-sized particles are already on the market. In America and Europe, nano-sized ingredients have been added to some fruit juices, processed meats, diet milkshakes and baby food.

But consumers would not know, as there are no requirements to label the presence of nanoparticles in food. Concerns are also growing about the possible harmful effects of nano-sized materials on human health and the environment.

In a comprehensive review of the issue, a British researcher, Dr Qasim Chaudhry, and his team conclude there are major gaps in knowledge about the safety of nanoparticles. "The toxicological nature of hazard, likelihood of exposure and risk to consumers from nanotechnology-derived food and food packaging are largely unknown," says Chaudhry, of Britain's Department for Environment, Food and Rural Affairs' Central Science Laboratory. Their study is published in this month's Food Additives and Contaminants journal.

Evidence that nanoparticles are more chemically reactive than larger particles, and that some are toxic to cells has prompted the environmental group Friends of the Earth, as well as the NSW Greens, to call for a moratorium on the use of nano-sized ingredients in food, food packaging or surfaces that can come into contact with food.

Friends of the Earth spokeswoman, Georgia Miller, says it is possible nano-sized ingredients are already present in Australian food, but without labelling or regulations it is impossible to know. "There is no way for anyone to choose to eat nano-free," says Miller, co-author of a report called Out Of The Laboratory And Onto Our Plate, Nanotechnology In Food And Agriculture.

Food Standards Australia New Zealand says it is not aware of any commercially sold foods in Australia that have been developed using nanotechnology, and says "robust regulatory arrangements to ensure the safety of food" are in place.

Nanotechnology a 'bigger concern' than GM foods

Opponents to nanotechnology say it is a much scarier prospect than GM food, and while it can make food look better and last longer, there are fears about how it might affect the human body.

The regulator now faces the difficulty of ruling when packaging becomes part of the food.

The CEO of Food Standards Australia New Zealand, Steve McCutcheon, says it is called interactive packaging, where the food takes in chemicals from the packet as it sits on the shelf.

"At the moment, the shelf life of prepacked salad vegetables is fairly short, but with the application of this technology we understand that you could actually package fresh salads, and they would be fresh still after the 30-day period on the shelf," he said.

The development that has given birth to the one-month fresh salad is called nanotechnology - working with particles thousands of times smaller that the width of a human hair.

It is not only for packaging, some companies want to use nanoparticles as ingredients in the food itself.

"We understand that a company in the United States has applied for a patent to cover the use of titanium dioxide and silicone dioxide in chocolate, in nanoparticle form, to give the surface a gloss," he said.

Alert over the march of the 'grey goo' in nanotechnology Frankenfoods

Some critics have talked of the threat of the creation of a "grey goo" of tiny particles with hidden harmful properties.

Prince Charles has said it would be "surprising" if the technology did not "offer similar upsets" to thalidomide - the morning sickness drug that caused children to be born with deformed limbs.

Professor Vicki Stone, Professor of Toxicology at Napier University in Edinburgh, is concerned about unforeseen side effects.

"We know very little about the ability of nanoparticles to move around the body, to accumulate or to be excreted, or their potential to cause toxic effects in organs," she said.

However, nanotech advocates have remarkable claims for the technology. For example, foods are in development that are said to stave off the aging process.

On a more trivial level, they suggest it would be possible to create a fizzy drink that changes flavour according to the number of times the can is shaken.
