Plants accumulate carbon in the spring and summer, and they release it back into the atmosphere in the fall in winter. And a change in the landscape of the Arctic tundra, seen here, means that shrubs hold onto snow better, which keeps the organic-rich soils warmer and more likely to release carbon dioxide that's stored there.

This chart shows the levels of atmospheric carbon dioxide as measured from Point Barrow, Alaska, from 1974 to 2007. Not only has the general trend ticked upward, but the size of the seasonal swings (the "saw tooth" pattern) has increased year to year.
Plant life on our planet soaks up a fair amount of the carbon dioxide that pours out of our tailpipes and smokestacks. Plants take it up during the summer and return some of it to the air in the winter. And a new study shows that those "breaths" have gotten deeper over the past 50 years.
This isn't just a curiosity. Plant life is helping to reduce the speed at which carbon dioxide is building up in our atmosphere. That's slowing the global warming, at least marginally, so scientists are eager to understand how this process works. The new study provides some clues.
Ramin Iremadze, 13, is one of a dozen Georgians who responded to a filmmaker's call for young people with compelling stories to tell. His tale takes us to a rural mountain village, and deep within the culture of the former Soviet republic.
Considered in pieces, The Machine Which Makes Everything Disappear is poignant and often hard to watch. Tinatin Gurchiani's documentary takes an episodic look at contemporary youth in her home country of Georgia, weaving together a series of vignettes featuring young people Gurchiani found by putting out a casting call for anyone ages 15-25 who thought their lives were suited for film.
Amanda Seyfried plays girl-next-door porn star Linda Lovelace, who'd become a sensation in 1972's <em>Deep Throat</em> but later denounce her manager-husband (Peter Sarsgaard) as abusive and manipulative.

Sharon Stone is hardly recognizable in her role as Lovelace's old-school Catholic mother, Dorothy.

Cinema routinely peddles images of beautiful people in romantic situations, not to mention gauzily idealized visions of passion and intimacy. So it's a little counterintuitive when filmmakers depict sex as perilous — even when that's exactly what they've signed up to do.
This month, NPR's Backseat Book Club goes snooping in Nikki Maxwell's "private and confidential" Dork Diaries. But the secret's already gotten out; the series launched four years ago, and there are already 12 million books in print in 34 different languages. The sixth in the series — Tales From a Not-So-Happy Heartbreaker — was just published in June.
