U.S. military officials say the crash late Friday occurred during combat operations in Kunar province. The CH-47 Chinook went down about 240 kilometers east of the capital Kabul, not far from the Pakistan border. Military spokeswoman Lieutenant Tamara Lawrence says an investigation is under way to determine the cause of the crash. "But it is important to note that the crash was not due to any hostile action or enemy fire." She says the bodies of all ten soldiers have been recovered. More than 2,000 US and Afghan soldiers have been targeting Taliban insurgents in Kunar province since last month. It is one of the largest offensives since the US-led coalition ousted the Taliban from power in 2001.

Before the Columbia disaster,NASA said 28 shuttle flights were needed to build the International Space Station. Now Dr. Griffin says it can be done in just 16 before the fleet has to be retired in 2010. So how to achieve this feat:Well, Dr. Griffin has adopted a'build now, use later'philosophy. Previously the plan was for astronauts to do scientific research as they constructed the station. Now there will be no time for science,all 16 missions will be geared to sending up and bolting on the various bits of the International Space Station. Many of which had been built at great expense by the Japanese,Russian and European space agencies.

There are 350,000 billion particles in this tube.So nano technology is the science of the very small. But how small is small? Well imagine I was shrunk to a 1,000 times smaller. I'd be about as big as the eye of a fly, but nano is even smaller than that. In fact, much, much smaller. Imagine I was shrunk again, this time 10,000 times. I'd be about as big as a virus, but nano is even smaller than that. You'd have to shrink me another 100 times to get the nano version of me,a billion times smaller than the real me. Industry is already building devices on that scale. Here in Cambridge they're making very thin nano layers of a plastic that emits light when electrical current runs through it. The technology will soon be on the market,in mobile phones with very bright, energy-saving displays.

The United Nations food agency has warned that millions of Kenyans and Somalis are at grave risk of starvation if aid does not reach the region soon. On a visit to Northern Kenya, the head of the World Food Program said the situation there was as desperate as anything he had ever seen. There have been a few showers in Kenya in the past week,but hardly enough to even wet the ground in many areas. The head of the World Food Program has been the boarder with Somalia,where hundreds of cattle and goats have died, and the human population is struggling to survive. He said the world had not yet woken up to the crisis that is facing Kenya and the whole of Africa.

Diplomats from nearly 30 countries have condemned a major campaign against the media in Kenya for which the Kenyan government has admitted responsibility.
The diplomats described the action as an unacceptable attack on the freedom of the press. Earlier the Kenyan government confirmed that it had ordered police to carry out an overnight armed raid on the offices of a leading newspaper and its sister television station. They burned thousands of copies of the newspaper,The Standard. Three journalists from the paper later have appeared in court charged with publishing a false statement intended to cause alarm. John Michuki, the Kenyan Minister of State Security,was the first to admit the government was behind the raid.

The right of women in the United States to have abortions is being challenged by the state of South Dakota. Governor Michael Rounds has signed a law that will ban almost all abortions even in cases of rape or incest, and provides for five-year jail sentences for doctors who perform them. The only exception would be if a pregnant woman's life was at risk. Supporters of the bill say it's intended as a direct assault on the US Supreme Court's landmark ruling of 1973 which guarantees American abortion rights. Pro-abortion campaigners are expected to challenge the ruling,but a leading anti-abortion campaigner welcomed it.

Five percent of all school-age children in the United States have some form of attention deficit hyperactivity disorder, or ADHD. A research team at Washington University in St.Louis is studying ADHD to identify the genes that seem to increase the risk of developing the disorder. Washington University child psychiatrists declare it is clear that ADHD runs in families. ADHD has always been shown in twin and family studies to be extremely heritable—on the order of 70-80 percent—just as heritable as height,intelligence and many other behaviors. They also mention that understanding how genetics influence risk may make it possible to develop better and more specific treatment for the disorder. The study appears in the Journal of the American Academy of Child and Adolescent Psychiatry.

Scientists have warned that Africa could be faced with 25 per cent less water by the end of the century because of global warming. The researchers, based at the University of Cape Town,say the reduction in rainfall may not be anywhere near as great as that, but the actual water available could be substantially reduced because of the way it gathers in rivers and streams. They say semiarid regions such as southern Africa and the Sahel are likely to be worst affected.

Dana Buchman is a celebrated American fashion designer. Her line of women's clothing can be found in major department stores around the country. Now, Ms. Buchman is in the headlines,not because of her spring collection, but because of her new book, A Special Education: One Family's Journey Through the Maze of Learning Disabilities, revealing her difficult and transformative acceptance of her older daughter—Charlotte's serious learning disabilities.
In addition to difficulty in understanding written words,4-year-old Charlotte had trouble counting. She couldn't tell a story,moved awkwardly and had absolutely no sense of direction. Her mother feared those symptoms would affect not only her schoolwork,but her ability to function in the real world as well.
