From Simon Mallett
I can’t see much call for a beefburger made from lab-grown meat that costs £250,000 (10 August, p 10), but I can see a demand for more exotic varieties.
How about mammoth burgers created from a single preserved stem cell? And, taking it to extremes, with a single stem cell donated by a celebrity: anyone for Bieber burgers?
