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.
I adore time-travel pictures like Looper no matter how idiotic, especially when they feature a Love That Transcends Time. I love Somewhere in Time with Christopher Reeve and Jane Seymour, The Time Traveler's Wife, even The Lake House with Keanu Reeves and Sandra Bullock in different years sending letters through a magic mailbox. So terrible. So good. See, everyone wants to correct mistakes in hindsight, and it's the one thing we cannot do. Except vicariously, in movies.
One night in 1984, British scientist Frances Ashcroft was studying electricity in the body and discovered the protein that causes neonatal diabetes. She says she felt so "over the moon" that she couldn't sleep.
By the next morning, she says, she thought it was a mistake.
But luckily, that feeling was wrong, and Ashcroft's revelation led to a medical breakthrough decades later, which now enables people born with diabetes to take pills instead of injecting insulin.
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).
<strong>Pathfinder, 1997: </strong>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.
<strong>Spirit, 2010:</strong> 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.
<strong>Opportunity, 2004: </strong>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.
<strong>Curiosity 2012:</strong> 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.
This week, we've been taking time to listen to several world leaders address the U.N. General Assembly in New York with special emphasis on the looming crisis over Iran's nuclear ambitions. We heard from President Obama and Republican presidential nominee Mitt Romney on Tuesday, from Iranian President Mahmoud Ahmadinejad yesterday. Today, Israeli Prime Minister Benjamin Netanyahu addressed the gathering and outlined the situation in stark terms. He warned that Iran will have enough enriched uranium to make a nuclear bomb by next summer.
This is TALK OF THE NATION. I'm Neal Conan in Washington. More than 38 million kids get their lunches through the National School Lunch Program, and with more than a third of the nation's youngsters overweight or obese, the cafeteria has become a battleground.
