World's first lab-grown burger to be cooked

A group of scientists from the Netherlands will introduce the world's first in-vitro burger made in a laboratory.

The process involves taking the stem cells from cows and growing them in petri dishes until they have formed thousands of muscle fibres.

Supporters of the laboratory burgers and animal activists say that it will reduce the need for factory farming.
