Washington, Sept 13 : The White House has again launched an attack on Bob Woodward''s new book “The War Within: A Secret White House History, 2006-2008” that criticizes President Bush''s handling of the Iraq war.

It argues that the author’s opinions in the book are not supported by his own reporting.

According to the Washington Post, the book depicts an administration riven by dissension over Iraq war strategy in 2006 and says Bush privately believed U. S. efforts were failing even while declaring publicly that the war was being won.

Washington, Sept 13 : Developing countries including China and India, are showing signs of economic cooling as the effects of the downturn that started in the United States continue to spread around the globe, says an expert.

"Basically, what you''ve got is the emerging world now slowing at the same time as the developed world. Though the magnitude of their slowdown is a lot more modest, it is a negative for the global economy. The question now, obviously, is how much will they slow down,” the Washington Post quoted Michael Hartnett, chief emerging markets strategist for Merrill Lynch, as saying.

These fears that booming emerging markets are becoming caught up in a global slowdown have helped send the dollar soaring this week.

Washington, Sep 13 : A former aide to Hillary Clinton’s campaign has told CBS News that the media have been much harder on Republican vice presidential nominee Sarah Palin than the other candidates in the race, and as a result “have growing credibility problems.”

Washington, September 13: Scientists at the University of Edinburgh, UK, have devised a clever method to purify parasitic organisms from their host cells, a major advance that can allow them to gain deeper insights into the biology of organisms that cause millions of cases of disease each year.

Many infectious pathogens have a complex life cycle alternating between free-living creature and cell-enclosed parasite. A thorough analysis of the proteins that help them undergo this lifestyle change can prove very useful for drug or vaccine development

However, separating the parasites from their host cell for detailed study has been extremely difficult to date.

Washington, September 13: New theory work at the U. S. Department of Energy’s Thomas Jefferson National Accelerator Facility has shown that more than half of the spin of the proton is the result of the movement of its building blocks: quarks.

It was thought that the spin of the proton would come from its quarks, but experiments beginning with the European Muon Collaboration in the 1980s have established that the quarks’ spin accounts for only one third of the proton’s spin.

Researchers thus began investigating other sources of the proton’s spin.
