...Green plants use light to transform carbon dioxide, absorbed from the atmosphere, and water into organic compounds, with oxygen as a by-product. The process is called photosynthesis, and it enables forests like Ulu Masen to play a critical role in regulating our climate. Forests store an estimated 300 billion tons of carbon, or the equivalent of 40 times the world's total annual greenhouse-gas emissions - emissions that cause global warming. Destroy the trees and you release that carbon into the atmosphere, putting the great challenge of our age - averting catastrophic climate change - beyond reach. Forest destruction accounts...
...leaders of forest-rich Brazilian states Amazonas and Mato Grosso - at a climate summit in Los Angeles, where they called upon governments to include REDD within the global framework for combating climate change. Sun of Carbon Conservation hopes one day to see "a global infrastructure of forest factories, producing oxygen and absorbing carbon dioxide."

Well, one reason is that starting a cable channel is hard. She already tried it once with Oxygen, now owned by NBC, and home to many reality shows that feature Janice Dickinson or have names that smack of ratings desperation like The Naughty Kitchen and Bad Girls Club. OWN, says Oprah, will reflect her "vision, values and interests." (Which Oxygen never quite did.) (See the top 10 skanky reality shows...
...prospects for the future. If humans are ever going to establish a long-term presence on the moon, they will need water to drink, and tapping a local supply would be a lot more convenient than lugging it from Earth. Beyond that, water can be split into hydrogen and oxygen - the former makes pretty good rocket fuel, and the latter is useful for breathing...
...were present and in what proportions, but also which genes these bugs were actively using in different conditions. Before such genomic-analysis technology became available, researchers could study only the gut microbes (animal or human) that could be cultured outside their intestinal home - something that not all of the oxygen-shunning bugs were amenable to - but never the complete microbiota of the gut. "We cannot recapitulate the entire microbial diversity that exists in these complex communities. We simply don't know how to culture them, so we could miss a lot of diversity," says Gordon...
