Lab-grown meat is first step to artificial hamburger

Dutch scientists have used stem cells to create strips of muscle tissue with the aim of producing the first lab-grown hamburger later this year.

The aim of the research is to develop a more efficient way of producing meat than rearing animals.

At a major science meeting in Canada, Prof Mark Post said synthetic meat could reduce the environmental footprint of meat by up to 60%.

"We would gain a tremendous amount in terms of resources," he said.
