A team led by Mark Post at Maastricht University in the Netherlands has developed-- and now served for taste-testing-- a beef burger grown in a laboratory from cow stem cells. The $330,000 project, funded by Google co-founder Sergey Brin, is touted as a step towards combating food insecurity and climate change. Post says its crucial the burger "look, feel and taste like the real thing," before scientists focus on scaling the so-called cultured beef for market.
