Growing concern surrounds a new national security threat, an insidious trend that could foster terrorism worldwide and draw our armed forces into messy regional conflicts in Africa, Asia and Latin America.
When Martin Marshall started looking for his dad about three years ago, he had a fantasy: One day, he might sit down over a cup of coffee with a half-sibling he'd never even met and hear a few stories about the father he'd never known. It hasn't exactly worked out that way.
After four years, America's cost for the war in Iraq has reached nearly $500 billion — more than the total for the Korean War and nearly as much as 12 years in Vietnam, adjusting for inflation. The ultimate cost could reach $1 trillion or more.
America is drunk on ethanol. Farmers in the Midwest are sending billions of bushels of corn to refineries that turn it into billions of gallons of fuel. Automakers in Detroit have already built millions of cars, trucks and SUVs that can run on it, and are committed to making millions more. In Washington, politicians have approved generous subsidies for companies that make ethanol.
Maybe it's the weird winter weather, or the newly Democratic Congress. Maybe it's the news reports about starving polar bears, or the Oscar nomination for Al Gore's global warming cri de coeur, "An Inconvenient Truth." Whatever the reason, years of resistance to the reality of climate change are suddenly melting away like the soon-to-be-history snows of Kilimanjaro.
The Hubble Space Telescope has shown that a mysterious form of energy first conceived by Albert Einstein, then rejected by the famous physicist as his "greatest blunder," appears to have been fueling the expansion of the universe for most of its history.
David M. Walker sure talks like he's running for office. "This is about the future of our country, our kids and grandkids," the comptroller general of the United States warns a packed hall at Austin's historic Driskill Hotel. "We the people have to rise up to make sure things get changed."

Astronomers say they have found the best evidence to date for "dark matter," that mysterious invisible substance that is believed to account for the bulk of the universe's mass.
Shampoo, iPods and Starbucks lattes have suddenly become security threats. Terrorists could easily slip a few apparently innocuous items past airport security and assemble them into a lethal explosive once aloft, security experts said.
When Gina O'Brien decided she no longer needed drugs to quell her anxiety and panic attacks, she followed doctor's orders by slowly tapering her dose of the antidepressant Paxil. The gradual withdrawal was supposed to prevent unpleasant symptoms that can result from stopping antidepressants cold turkey. But it didn't work.
It was a science fiction fantasy come true: Ten years ago this summer, NASA announced the discovery of life on Mars.
Actress Brooke Shields has a pretty impressive pedigree — hanging from her family tree are Catherine de Medici and Lucrezia Borgia, Charlemagne and El Cid, William the Conquerer and King Harold, vanquished by William at the Battle of Hastings.
Whoever it was probably lived a few thousand years ago, somewhere in East Asia — Taiwan, Malaysia and Siberia all are likely locations. He — or she — did nothing more remarkable than be born, live, have children and die.
In just eight months, the U.S. Army Corps of Engineers has done years of work on the Katrina-battered ramparts around New Orleans.
Physicists announced Thursday that they now have the smoking gun that shows the universe went through extremely rapid expansion in the moments after the big bang, growing from the size of a marble to a volume larger than all of observable space in less than a trillion-trillionth of a second.
A beautifully preserved fossil from southern Germany raises questions about how feathers evolved from dinosaurs to birds, two paleontologists argue in a study published Thursday.
John D. Barrow, a British scientist and writer whose work explores fundamental questions about the universe and humanity's place in it, has won a religion award billed as the world's richest annual prize.
When it comes to the price of mice, you pay more for defects. A mouse with arthritis runs close to $200; two pairs of epileptic mice can cost 10 times that. You want three blind mice? That'll run you about $250. And for your own custom mouse, with the genetic modification of your choosing, expect to pay as much as $100,000.
