Maastricht University vascular physiology professor Mark Post successfully engineered the world’s first edible hamburger earlier this year using bovine stem cells. The in-vitro hamburger will be cooked and consumed for the first time live on stage on August 5, 2013. A real-time online stream of the demonstration will allow viewers from all over the world to watch professor Post explain the technology of lab-grown meat, as well as cook and serve the burger before an invite-only audience in London. Though the in-vitro hamburger cost nearly $325,000 to produce, the process will likely move toward replacing animal materials with non-animal ones––a step that could help bring down costs. “If it can be done more efficiently, there’s no reason why it can’t be cheaper,” Post tells The New York Times.
