Plankton make up 98 percent of the biomass of ocean life and provide half of the oxygen on the planet. Scientists are working to figure out how climate change may be affecting these important microorganisms.

The 118-foot research schooner Tara made an around-the-world expedition over 21/2 years. Scientists aboard discovered up to a million new species of plankton. Now begins the work of determining how climate change might be affecting these microorganisms.
President Obama and his Republican challenger, Mitt Romney, are prepping for Wednesday's presidential debate. It's a well-worn tradition now, but it wasn't always that way.
The 1960 Kennedy-Nixon face-off wasn't just the first televised presidential debate, it was also the first presidential debate in more than a century.
Four years earlier, a young German emigre named Fred Kahn, a student at the University of Maryland, wanted to see whether the nominees — Dwight Eisenhower and Adlai Stevenson — might want to engage with students.
Betto Arcos is the host of Global Village, a world music show on KPFK in Los Angeles, and a native of Xalapa, capital city of the Mexican state of Veracruz. He recently spoke with Guy Raz, host of weekends on All Things Considered, about son jarocho — a style of music played mostly in the south of his home state. He says the music is so vibrant because it comes from the Caribbean side of Mexico and has all the influences of that region: African, indigenous and Spanish.
You probably don't give much thought to the phrase "Made in China" when you see it written on the bottom of your coffee mug, or on the tag of your T-shirt, but Americans have traded with China for hundreds of years.
In his new book, When America First Met China, Eric Jay Dolin takes us back to the beginning of the long and complicated trade relationship between the two countries.
President Obama speaks during a campaign event at University of Colorado Boulder Sept. 2. He and his Republican challenger, Mitt Romney, will have their first debate at the University of Denver on Wednesday.
Colorado is a good venue for a presidential debate focusing on domestic issues. The first of three highly anticipated debates between President Obama and his Republican challenger, Mitt Romney, will take place Wednesday at the University of Denver.
The state is known for its independent voting streak, and much like the rest of the country, there are sharp political divides about the role of government in the economy. In Colorado, those differences grow from two distinct population centers.
President Obama and Republican rival Mitt Romney both barnstormed Ohio this week, holding rallies just miles apart in the state's northwest. Obama's event was smack in the middle of Wood County, with Romney's just north.
The county may have a population of only 125,000, but it has an outsized importance in presidential elections.
"Since 1960, [Wood County] has predicted every election except for one," says Wood County GOP Chairman Matt Reger. "I think that it is a microcosm of Ohio, which in some parts is a microcosm of the United States."
Lorie Miller bends over her grandparents' grave in north Philadelphia. She holds a two-inch brass square she's going to attach next to the headstone's names and dates.
Printed onto that square is a QR code — that square digital bar code you can scan with a smartphone. Miller peels off the back of her square to expose the adhesive and pushes it into place. The headstone, which otherwise looks the same as many others around it, has just jumped into the modern age.
Archbishop John J. Myers stands outside Cathedral Basilica of the Sacred Heart in Newark, N.J. The archbishop has urged followers to assess the presidential candidates for their views on abortion and gay marriage.
Since 1972, every single presidential candidate who has won the popular vote has also won the Catholic vote. But with Catholics making up one in every four voters, pinning down what exactly the Catholic vote isbecomes tricky.
Robby Benson began his career at the age of 12, on the Broadway stage, and became a teen heartthrob in the '70s, starring in films such as Ode To Billy Joe, Ice Castles and One on One, which he co-wrote. He was also the voice behind the Beast in the 1991 Disney film, Beauty and the Beast.
In the early '90s, Ben Folds Five achieved underground success by playing the college circuit, selling out small clubs all across the country.
That all changed with the success of its 1997 album Whatever and Ever Amen. Its hit single "Brick" went to No. 6 on the Billboard Modern Rock Tracks list, only the second single in the band's history to chart.
The western Afghan city of Herat has become a thriving hub for the money exchange business, a consequence of geography and politics. Money-changers throng the currency market carrying thick stacks of Iranian currency, much of it brought in by the hundreds of thousands of Afghan workers who earn their living in Iran.
While the stacks of crisp 100,000 rial notes that money-changers bring to the market might look like a small fortune, the 10 million rials in each of these stacks is worth less than $400, because the Iranian currency recently lost more than half of its value.
According to Bloomberg, President Obama and Mitt Romney have aired nearly 30,000 TV spots addressing the issue of trade with China, and that's just in the past month. Many of those ads aired in Ohio where both candidates are spending a lot of time. NPR's Sonari Glinton explains the Ohio-China nexus.
SONARI GLINTON, BYLINE: If there's a boogeyman in the Ohio presidential sweepstakes, it's China.
There may be international sanctions against Iran, but not in Afghanistan's border provinces with the Islamic Republic where trade and money-laundering are thriving. Every day, millions in Iranian currency are brought in by taxis ferrying passengers. The Iranian money is exchanged for dollars, which are then shipped back to Iran. American officials recently ordered the Afghan banks to crack down on this phenomenon and it appears to be having some effect.
