The head of the United States Anti-Doping Agency says Lance Armstrong knows the truth and he has decided that instead of airing every piece of evidence publicly and in front of an impartial court, the dethroned seven-time Tour de France winner has decided to "hold on to baseless soundbites."
Forests in the Southwest have become a fuel stockpile. A century of U.S. Forest Service policy of quashing all fires has allowed forests to become overgrown, and now a warming climate is making the problem worse.
Scientists are trying to defuse these green time bombs. Is it too late?
A new military study suggests that some soldiers suffer mild traumatic brain injuries even before they go to war. These concussions, as they're also called, can come from taking "combatives" classes that teach hand-to-hand fighting during the soldiers' training.
Talk in Israel of a military strike on Iranian nuclear facilities has reached a fever pitch. Last week brought the news of an alleged "war plan" leaked to a blogger. This week, a well-informed military correspondent in Jerusalem reported that Israeli Prime Minister Benjamin Netanyahu is "determined" to attack Iran before the U.S. election.
This week, first lady Michelle Obama was doing something she loves to do, talking about nutrition with kids. She hosted the first state dinner for children, welcoming 54 of them and their parents to the White House.
"This is the hottest ticket at the White House, right here, because of all of you," Obama said to the children, who ranged in age from 8 to 12.
Gunmen wearing Afghan police and army uniforms have killed 40 U.S. and NATO troops so far this year, and the top American commander in Afghanistan says there is no single reason — and no simple solution.
Taliban infiltrators, disputes between NATO and Afghan security forces, and even the timing of Ramadan, the Muslim holy month, are all factors, according to Gen. John Allen.
"We think the reasons for these attacks are complex," says Allen, who spoke by video link from Kabul on Thursday. Ten of the American deaths have come in just the past two weeks.
We're gonna take a global look stroll now, looking at street art, everything from a mural of creepy pink bunnies in San Francisco to a sculpture of a brick train engine stuck in the ground in New Zealand to a street light covered with knitting in Bristol, England. It's all collected on a website and a mobile app that will launch at the end of the month. It's called Big Art Mob and it's the creation of Alfie Dennen, who joins me from London to talk about it.
During the next two weeks, the major political parties will assemble their faithful in Tampa, Fla., and Charlotte, N.C., to officially nominate their presidential tickets. These conventions were once places of high political drama. But over the decades, as the primary system has determined the candidates well in advance, conventions have become political theater. With that in mind, there's much to be said on staging in politics — not substance, but style.
Fire scientists are calling it "the new normal": a time of fires so big and hot that no one can remember anything like it.
One of the scientists who coined that term is Craig Allen. I drive with him to New Mexico's Bandelier National Monument, where he works for the U.S. Geological Survey. We take a dirt road up into the Jemez Mountains, into a landscape of black poles as far as you can see.
Republican Rep. Todd Akin's decision to stay in the U.S. Senate race in Missouri is likely to leave him with support from the state's evangelical community, but not much more, says a political scientist at the University of Missouri, St. Louis.
The question of whether to circumcise a newborn son is no question at all for most observant Jews. In Europe, the practice has come under fire. This summer, a German regional court ruled that circumcision is physical abuse, and a Swiss hospital temporarily banned the procedure. The debate has infuriated Jewish community leaders there.
In Israel, even the most secular Jews overwhelmingly have their sons circumcised. But the debate in Europe has drawn attention to a still small but growing number of Israeli Jews who are forgoing the procedure.
Ten years ago, a piece of ice the size of Rhode Island disintegrated and melted in the waters off Antarctica. Two other massive ice shelves along the Antarctic Peninsula had suffered similar fates a few years before. The events became poster children for the effects of global warming. But a new study finds that the story isn't quite so simple.
There's no question that unusually warm air triggered the final demise of these huge chunks of ice. But a lingering question is whether these events can be attributed to human-induced global warming.
Cuba has hot weather, hot music, hot politics and hot Cubans. So why is the food so bland?
Tourists who have visited the island, particularly Cuba's state-run restaurants, know that Cuban chefs are deeply fond of frying their ingredients, but the range of seasonings tends to span from salt to garlic, with not much else in between.
Enter the Spice Man. He is Cedric Fernando, co-proprietor of the first and only Indian restaurant in Cuba, called Bollywood. And he's definitely turning up the heat in the kitchen.
Time now for your comments and some corrections. On Monday, we got some modern Chinese history wrong. We described a phrase used famously by Chairman Mao, let 100 flowers bloom, as launching the cultural revolution. But Mao's 100 flowers campaign, a brief period of openness in China, occurred one decade before the brutal crackdown of the Cultural Revolution.
It's a typical day at a Head Start center near downtown New Haven, Conn., and restless 3- and 4-year-olds squirm and bounce on a colorful shaggy rug vying for their teacher's attention. Down the hallway several women make their way to a parenting class, stopping to marvel at a 4-month-old baby.
What you don't see, says the center's Keith Young, is men, fathers.
On a muggy summer afternoon in Greenpoint, Brooklyn, a dozen people are hard at work on the patio behind a local church. They're stripping old bicycles of their brakes, cables and chains, and sanding and spray-painting them white.
But behind the lighthearted chatter, there's a more somber purpose to this gathering: They're building "ghost bikes."
Painted all white and adorned with colorful notes and flowers, ghost bikes are the cycling community's equivalent of roadside shrines dotting the highway; they mark the spot where a rider was killed in traffic.
