Apples That Don't Turn Brown

A Canadian biotechnology company has asked the U.S. to approve a genetically modified apple that won't brown soon after its sliced, saying the improvement could boost sales of apples for snacks, salads and other uses. Essentially, the genes responsible for producing the enzyme that induces browning have been silenced in the apple variety being marketed as "Arctic."
Luckily, the approval process can take years, and it's not clear the apples will be accepted even if they pass government inspection.
