Our analysis clearly reveals for the 3 GMOs new side effects linked with GM maize consumption, which were sex- and often dose-dependent. Effects were mostly associated with the kidney and liver, the dietary detoxifying organs, although different between the 3 GMOs. Other effects were also noticed in the heart, adrenal glands, spleen and haematopoietic system. We conclude that these data highlight signs of hepatorenal toxicity, possibly due to the new pesticides specific to each GM corn. In addition, unintended direct or indirect metabolic consequences of the genetic modification cannot be excluded.

Of the 84,000 chemicals in commercial use in the United States – from flame retardants in furniture to household cleaners – nearly 20 percent are secret, according to the Environmental Protection Agency, their names and physical properties guarded from consumers and virtually all public officials under a little-known federal provision.

Under the 1976 Toxic Substances Control Act, manufacturers must report to the federal government new chemicals they intend to market. But the law exempts from public disclosure any information that could harm their bottom line.

If the course of human history is any model, then the wheels are already turning on Earth’s sixth mass extinction, thanks to habitat destruction, pollution and now global warming, a scientific analysis of millions of years of data revealed Friday.

That means North American mammals are well on the way - perhaps as much as half way - to a level of extinction comparable to other epic die-offs, like the one that wiped out the dinosaurs.

Drugs money worth billions of dollars kept the financial system afloat at the height of the global crisis, the United Nations’ drugs and crime tsar has told the Observer.

Antonio Maria Costa, head of the UN Office on Drugs and Crime, said he has seen evidence that the proceeds of organised crime were “the only liquid investment capital” available to some banks on the brink of collapse last year. He said that a majority of the $352bn (£216bn) of drugs profits was absorbed into the economic system as a result.

As the Copenhagen meeting on climate change opens, we are getting mixed signals. At one extreme are the “disbelievers,” who say that serious consequences from global warming, if it is really happening, are still decades away so why should people be saddled with higher energy costs now. If the polls are correct the disbelievers now constitute a majority of the American electorate.

At the other extreme are the climate scientists who are telling every media outlet that will listen that the proposals being discussed at Copenhagen are nowhere near enough to save mankind from destruction. Some are saying that a five degree Centigrade increase in the average global temperature may be enough to do in mankind. Food will no longer grow in sufficient quantity to keep all 8 billion of us fed.
