August 5/London/Times of India -- Scientists have unveiled the world's first lab-grown beef burger, serving it up to volunteers in London in what they hope is the start of a food revolution.
The 140g (about 5oz.) patty, which cost more than 250,000 euros ($330,000) to produce, has been made using strands of meat grown from muscle cells taken from a living cow.
