Scientific American Magazine: At the Edge of Life's Code
Dimanche 16 Mars 2008 - 22:00 - 9 mois, 3 semaines depuis - Presse spécialisée - Scientific American
On an airport shuttle bus to the Kavli Institute for Theoretical Physics in Santa Barbara, Calif., Chris Wiggins took a colleague’s advice and opened a Microsoft Excel spreadsheet. It had nothing to do with the talk on biopolymer physics he was invited to give. Rather the columns and rows of numbers that stared back at him referred to the genetic activity of budding yeast. Specifically, the numbers represented the amount of messenger RNA (mRNA) expressed by all 6,200 genes of the yeast over the course of its reproductive cycle. “It was the first time I ever saw anything like this,” Wiggins recalls of that spring day in 2002. “How do you begin to make sense of all these data?”

Where would we be without bananas? The silent-movie industry, founded on images of men in bowler hats being launched into the air by banana skins, might never have gotten off the ground, so to speak. Kids would have to pack drippy citrus into their lunch boxes. The band Bananarama could have been the more fetid Apricotarota. When Shakespeare “let slip the dogs of war,” what do you think they slipped on?
