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.

Use of antidepressant drugs in the United States doubled between 1996 and 2005, probably because of a mix of factors, researchers reported on Monday.

About 6 percent of people were prescribed an antidepressant in 1996 – 13 million people. This rose to more than 10 percent or 27 million people by 2005, the researchers found.

“Significant increases in antidepressant use were evident across all sociodemographic groups examined, except African Americans,” Dr. Mark Olfson of Columbia University in New York and Steven Marcus of the University of Pennsylvania in Philadelphia wrote in the Archives of General Psychiatry.

“Not only are more U.S. residents being treated with antidepressants, but also those who are being treated are receiving more antidepressant prescriptions,” they added.

More than 164 million prescriptions were written in 2008 for antidepressants, totaling $9.6 billion in U.S. sales, according to IMS Health.

A group of doctors in the UK are mounting a legal and political campaign to overturn the suicide verdict in the death of a British doctor who was found dead shortly after exposing falsehoods about the justification for the Iraq war.

Dr. David Kelly was found dead in 2003 in a forest near his home in Oxfordshire. An inquiry into his death concluded that he had bled to death during a suicide attempt.

But 13 UK doctors are now challenging that assertion — and in doing so, renewing suspicions the doctor may have been murdered after it was revealed he was the mole for a BBC report that said evidence used to launch the Iraq war had been “sexed up.”

He was intending to reveal that he warned Prime Minister Tony Blair there were no weapons of mass destruction anywhere in Iraq weeks before the ­British and American invasion. He had several discussions with a publisher in Oxford and was seeking advice on how far he could go without breaking the law on secrets.

Following his death, his computers were seized and it is still not known if any rough draft was discovered by investigators and, if so, what happened to the material.

Dr Kelly was also intending to lift the lid on a potentially bigger scandal, his own secret dealings in germ warfare with the apartheid regime in South Africa.
