Digital textbooks are transforming the way many students learn. All the Fairfax County Public Schools have begun using online course material for their middle- and high-school students. This school year, the schools shifted from hard cover to electronic textbooks for social studies in its middle and high schools. The switch came after digital books were used in 15 schools last year. "Our students come to us technologically ready to use resources from a variety of different places," says Assistant Superintendent Peter Noonan. "The world is changing consistently. The online textbooks can change right along with the events that are happening." There's a significant financial benefit as well. "Usually it is between $50 and $70 to buy a textbook for each student," Noonan says, "which adds up to roughly $8 million for all of our students. We actually have purchased all of the online textbooks for our students for just under $6 million."

A man was arrested on suspicion of attempting to carry explosives through a security checkpoint at an airport, authorities said. Trey Scott Atwater was taken into custody Saturday morning after Transportation Security Administration agents spotted what they described as a suspicious item. The item was in his carry-on during X-ray screening at a security checkpoint at the airport, an FBI spokesman said in a statement. Neither the FBI nor the TSA identified the explosives, though an airport spokeswoman said the items were "wrapped in military grade wrapping" and are in the possession of the police. At no time was there any danger to the people at the airport. The airport terminal was temporarily evacuated while authorities "conducted a sweep, and deemed all clear," said a city spokeswoman. Atwater has been arrested on a federal count of attempting to get on an aircraft with an explosive.

In Dakar, psychiatric patients attend regular art therapy classes to help treat mental disorders. The therapy can be a useful technique to complement traditional forms of psychotherapy. Psychiatrists in the Senegalese capital's main hospital see it as an essential part of the healing process. Art as psychotherapy is still relatively new in Senegal. Dr. Tabara Sylla, the hospital's chief psychiatrist, uses art therapy, medication and classical forms of psychotherapy in her practice, treating everything from chronic depression to alcohol abuse and schizophrenia. At first the project started as a way to keep patients busy in the afternoon, rather than have them sitting around smoking. It soon became clear that art was creating a communication bridge between patient and doctor. More and more now, she says, art workshops have become essential therapy --- so much that she cannot imagine this psychiatric unit without them.

The Federal Aviation Administration, or FAA, the government agency that regulates civil aviation in the United States, announced new rules this month to combat pilot fatigue. The new guidelines, which will go into effect in two years, call for reducing the number of pilots' on-duty hours and giving them a 10-hour rest period between shifts, so they can get at least 8 hours of uninterrupted sleep. The new rules apply to only pilots of passenger airlines. FAA determined that including pilots who fly cargo planes --- a large segment of the aviation industry --- would add too much to the cost of implementing the changes. But the Independent Pilots Association has filed a lawsuit asking the government to set one level of safety for all pilots.

News Item 5 (For Question 29and 30)
The world will need to double food production within the next three decades in order to feed a rapidly growing and increasingly affluent population, which is projected to grow from 7 billion today to 9 billion. A United Nations report says reaching that goal will require major increases in intensive, high-efficiency livestock operations for both meat and dairy production. The report also says that intensive livestock operations can pose serious ecological risks. And that's why environmental critics are calling instead for reductions in global livestock production, and urging people to consume less, not more, meat in their diets. Feeding today's population is a challenge for an already-stressed environment. The challenge is how to ensure food without increasing animal numbers and having an impact on fragile lands and our resource bases. More than half of the agricultural land in the world is used to raise and feed livestock. Those farm animals are also responsible for 18 percent of the greenhouse gases released into the atmosphere every year. Experts agree that the next few decades will present a puzzle, how to feed nine billion people without wrecking the planet in the process.
