sciencehabit writes: "Close to meat. Not that juicy." That was Austrian food trend researcher Hanni Rützler's verdict on the world's first lab-grown beef patty, presented in London today at a tightly orchestrated and widely covered media event. Rützler was one of two people invited to taste the burger assembled from thousands of tiny strips of beef grown by Dutch researcher Mark Post at his lab at Maastricht University in the Netherlands; the other guinea pig was Chicago, Illinois-based author Josh Schonwald. Perhaps the most concrete news to come out of the event was the unmasking of the mysterious billionaire who financed the project to the tune of $375,000. He is Google co-founder Sergey Brin, who has an interest in environmental issues and who praised Post in a video message for thinking big. "There are basically three things that can happen going forward. One is that we all become vegetarian," Brin said. "The second is we ignore the issue and that leads to continued environmental harm, and the third option is we do something new."
