Artificial meat

I distinctly remember the first time I tasted fake meat. The plate arrived with what looked like sausages - the shape was intact but the colour was a little pale. The taste was so revolting ...

The Dutch team that crafted the world's first lab-grown meat burger, which cost 215,000 pounds to make, says a cheaper version of the product could hit the market in five years.

Scientists and businesses working full steam to produce lab-created meat claim it will be healthier than conventional meat and more environmentally friendly. But how much can they improve on old-school pork or beef?
