But a recent study made waves when it suggested that CT scans may eventually account for up to 5 percent of new cancer cases in the U.S. each year.

In nature, evolution is slow. Genes change little by little, over thousands or even millions of years. In the lab, though, scientists have found ways to speed this process up — a method called directed evolution. It’s been used to design better medicines, cleaner industrial enzymes, and even Nobel Prize–winning breakthroughs.
