The idea that milk may diminish the potential heart-health benefits of tea has been a topic of some debate. Lots of us can't imagine black tea without a little dairy to cut the bitterness. But, according to this research going back to 2007, we might want to at least consider trying, say, a nice cup of green tea sans sugar or cream.
American Airlines planes sit on the tarmac at Miami International Airport this month. Reports indicate that American Airlines has canceled somewhere between 2 and 5 percent of flights in recent days, reportedly blaming a surge in pilot sick days and maintenance write-ups by pilots.
Pat Henneberry is an airline's dream customer. She flies all week, every week, and buying an $800 ticket so that she can have full flexibility is standard operating procedure. She's an American Airlines platinum customer. But she is fed up with the endless delays and cancellations.
NASA says it has found proof that water shaped the rocks on the left, in a photograph taken by the Mars rover Curiosity (left). For comparison, the agency released an image of rocks from the Earth (right).
Pathfinder, 1997: The first mission to land a rover on Mars, Pathfinder touched down in Ares Vallis, an ancient flood plain in the planet's northern hemisphere. Among the 2.3 billion bits of data sent back by the lander and its rover, Sojourner, were 15 chemical analyses of rocks and soil, which suggested Mars had once had liquid water and a thicker atmosphere.
Spirit, 2010: When NASA's Spirit rover got stuck in Martian sand, it proved to be a lucky break: The spinning wheel churned up soil that provided evidence of rocks formed in the presence of water.
Opportunity, 2004: Opportunity discovered tiny mineral spheres — nicknamed blueberries — poking out of rocks that were likely formed by water. Researchers using Opportunity's science instruments identified them as concretions rich in the mineral hematite, deposited by water saturating the bedrock.
Curiosity 2012: A wider view of the outcrop of a former streambed shows bedrock that scientists believe was likely exposed by meteorites striking the surface of Mars.

NASA's Curiosity rover has found definitive proof that water once ran across the surface of Mars, the agency announced today. NASA scientists say new photos from the rover show rocks that were smoothed and rounded by water. The rocks are in a large canyon and nearby channels that were cut by flowing water, making up an alluvial fan.
"You had water transporting these gravels to the downslope of the fan," NASA researchers say. The gravel then formed into a conglomerate rock, which was in turn likely covered before being exposed again.
A battle is under way in Iowa over whether a state Supreme Court justice can keep his job.
Critics have launched an all-out campaign to throw him off the bench because of his ruling three years ago clearing the way for same-sex marriage. The judge's supporters are fighting back, but they may need to get over their reluctance to mix politics and the judiciary.
One topic you don't hear much about from Republican presidential nominee Mitt Romney is climate change. Like so much else, it's become politically divisive, with polls showing Republicans far less likely to believe in it or support policies to address it.
But two new groups aim to work from within, using conservative arguments to win over skeptics.
It's been more than a month since the government began accepting requests for its Deferred Action for Childhood Arrivals program, the Obama administration's policy for young people brought to the U.S. illegally as children. Hundreds of thousands of people are eligible for the program. So far, only 82,000 have applied.
Carlos Martinez is one of the 29 people who have actually gotten deferrals. It means that he won't be deported, and that he can get a work permit. Martinez applied for the deferred action program the first day.
New York, New York, it's a wonderful town! And Mark Helprin's new near-epic novel makes it all the more marvelous. It's got great polarized motifs — war and peace, heroism and cowardice, crime and civility, pleasure and business, love and hate, bias and acceptance — which the gifted novelist weaves into a grand, old-fashioned romance, a New York love story that begins with a Hollywoodish meet-cute on the Staten Island Ferry.
The Avengers has brought in more money than any other movie this year — more than $600 million domestically. And it's only going to make more, especially with the DVD release this week.
The Avengers features characters from Marvel Comics, but the No. 2 movie of the year was based on a character from rival DC Comics — Batman. It's just the latest skirmish in a long, long, long-running battle between Marvel fans and DC fans.
