EPA finds the courage to stop corporations from hiding safety data. It could help determine what’s in a nano-dispersant they want to use in the Gulf

EPA must be gulping down its energy drinks in large quantities, because after years of allowing corporations to withhold vital safety information, it screamed “stop” yesterday.
In the Federal Register, the agency said that it will no longer permit the obstruction of safety evaluations by allowing firms to hide behind age-old claims of business secrecy.

Needle-haters rejoice and developing nations may get a better shot at scarce vaccines.

A vaccine delivered by a nanopatch works as well as one delivered with a needle and syringe, but is pain free and uses 100 times less medication, according to researchers from the Australian Institute for Bioengineering and Nanotechnology.
“Because the nanopatch requires neither a trained practitioner to administer it nor refrigeration, it has enormous potential to [...]

Much ado about something nano-sized

The White House patted itself on the back and said that the federal government’s nanotechnology operation was doing a “commendable” job.
These words did not come from President Obama, but rather were the conclusion of the President’s Council of Advisors on Science and Technology and 12 leading civilian experts recruited to examine what the White House-run [...]

Nanoparticles used to target tumors can cause DNA damage across the body’s protective barriers

A team of British researchers is raising new and serious questions about the health risks posed by nanoparticles.

Feds question safety of nanosilver used in odor-eating clothing favored by astronauts, hikers and babies

They are bacteria-killers, more and more common in products we use every day and at least a million of them will fit on the head of a pin. But are silver nanoparticles safe?
Little is known about the health effects of these inventions.

Can EPA and the White House buck industry pressure to prevent regulation of nanotechnology?

Many public health activists cheered this week’s announcement by the Environmental Protection Agency that it plans to actually move ahead with research to better understand how manufactured nanomaterials may harm human health and the environment.

Nanotech may improve the world but how safe will the human race be?

Touted as our next Industrial Revolution, the use of nano particles continues to sweep across the global business world like the high tech tsunami it is.
Inventions and new applications fly off laboratory benches and out of clean rooms faster than patents can be filed or danger to public health even assessed.
Globally, sales of nano-based products [...]

Water. Water. Everywhere. Clean or poisoned?

Home much liquid did you consume today?  Was it clean?  Will you become ill, spawn a deformed child, get cancer, die a lingering death?
In an attempt to head off some of the pithy comments accusing me of being a fear monger, let me admit that, in this case, I am.
I don’t think most of us [...]

Nanoparticles in sunscreens have more to do with looks than safety, but are they safe?

Cutting edge nanoscience has put an end to the icky white coating of old sunscreens that that prevented the sun from harming your skin.
But scientists for consumer and environmental groups say that while nanosized sun-blocking ingredients like titanium dioxide and zinc oxide now rub on clear instead of white, very few of the engineered materials [...]

Nano packaging of food kills deadly bacteria, but government says no go.

One might think that a food-shipping container coated with nanoparticles that have been proven to destroy bacteria causing illness and death would be a coveted innovation.
Apparently not so.
William Norwood, president of nanoAgri Systems, said the Environmental Protection Agency told him that he wasn’t permitted to market his company’s new nanosilver, antibacterial packaging.
“This just doesn’t make [...]
