...nearly two centuries, researchers have suspected that sleep plays an important role in learning and memory. But it's only in the last decade that neuroscientists have discovered the most convincing evidence that memory is indeed dependent on sleep. The prevailing theory is that during deep sleep, the brain replays certain experiences from the day, which, in turn, strengthens the memory of what happened. It is thought that when it comes to factual memories, like names, faces, numbers or locations, memory consolidation happens only during deep sleep - a phase of non-rapid eye movement sleep. (The other broad type...
...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...
...leveraging their experience at building brands. "That's what our core strength is," says Munn, who spent most of his career working for consumer-products giant Unilever. "We're an idea-generating powerhouse."

In some cases, agencies work with clients to create...

After taking the lead role in fighting the rebels in 2004 and 2005, the peacekeepers have shifted their mission to supporting the Congolese army, providing fuel, transport, logistics and other help...
TIME: What is [former finance minister and now planning commission head] Trevor Manuel's new role in this new set-up? Is he, as some say, effectively a Prime Minister? Zuma: He is not a Prime Minister. He had the very specific task of helping me and the country to work out a national plan, to ask: where shall we be by this time? Where is the country going? His role is also to monitor and evaluate. The reason Trevor was appointed was because he had been minister of finance and had an understanding of the workings of all government...
