Chef Gordon Ramsay heads to Woodland Park for 'Kitchen Nightmares'
Mark Post, developer of the stem cell burger, poses before the first public tasting, in London, Monday, Aug. 5, 2013. For hamburgers that cost more than $300,000 to produce, you might expect fries and a shake too. But this is no ordinary burger being served to two volunteer taste-testers in London on Monday. This meat was grown in a laboratory from stem cells of cattle. Mark Post, whose team at Maastricht University in the Netherlands developed the burger after five years of research, hopes that making meat in labs could eventually help solve the food crisis and fight climate change.
