If artificial meat can be perfected, the costly process could eventually be moved to plantlike facilities where it can be produced far more quickly and efficiently.

Reports said last week that researchers could be just six months away from producing the world’s first artificial meat, using thousands of stem cells bred in a laboratory.

One is artificial meat, which is made in a giant VAT, and the other is nanotechnology, which is expected to become more important as a vehicle for delivering medication to livestock.
