Fake Burger, Fake

Here are some details about the $380,000 lab-grown hamburger unveiled yesterday in a weird publicity stunt. It was made with the help of a "'growth gel' cocktail of bovine fetal serum and antibiotics." Also: "The burger presented was made mostly of muscle cells, with beet juice and saffron added to impart a pinkish colour, and breadcrumbs to improve the consistency." [New Scientist]
