Diplomatic cables released by WikiLeaks show the pharmaceutical giant Pfizer hired investigators to find evidence of corruption against the Nigerian attorney general to pressure him to drop a $6 billion lawsuit over fraudulent drug tests on Nigerian children.

MIT neuroscientists have shown they can influence people’s moral judgments by disrupting a specific brain region – a finding that helps reveal how the brain constructs morality.

“You think of morality as being a really high-level behavior,” she says. “To be able to apply (a magnetic field) to a specific brain region and change people’s moral judgments is really astonishing.”

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.

The U.S. healthcare system is just as wasteful as President Barack Obama says it is, and proposed reforms could be paid for by fixing some of the most obvious inefficiencies, preventing mistakes and fighting fraud, according to a Thomson Reuters report released on Monday.

The U.S. healthcare system wastes between $505 billion and $850 billion every year, the report from Robert Kelley, vice president of healthcare analytics at Thomson Reuters, found.

“America’s healthcare system is indeed hemorrhaging billions of dollars, and the opportunities to slow the fiscal bleeding are substantial,” the report reads.

It’s a question that has baffled the worlds of agriculture and science – what is it that has caused the mysterious deaths of honey bees all over the world in the last five years? A new film may have the answer.

Vanishing of the Bees, which will be released in Britain next month, claims the cause is the use of a new generation of pesticides that weakens the bees and makes them more susceptible to other diseases.

Narrated by the British actress Emilia Fox, the 90-minute film tells the story of what has become known as colony collapse disorder.
