The Department of Energy Lawrence Berkeley National Laboratory's (Berkeley Lab) "Did You Ever Wonder" campaign has entered its third month with a new set of questions aimed at stimulating scientific curiosity. This month: "Did you ever wonder ... how to rebuild the surface of a cell? How to carve with light? What to do about leaky ducts?"

Featuring individual scientists who are investigating intriguing questions of human health, the environment, new technology, and nature's most fundamental principles, "Did You Ever Wonder" conveys the flavor of the diverse research done at Berkeley Lab (none of it classified) and the even more diverse collection of men and women who pursue that research.
