Wencke Petersen came to Liberia in late August to do what she normally does for Doctors Without Borders in hotspots all over the world — manage supplies.

For five weeks, she gave people the bad news.

Don't wait to be invited or encouraged to make a career in science, engineering or technology, Frances Arnold advises the young women she teaches at the California Institute of Technology. If you're a scientist, she says, you should know how to solve a problem.

"Bemoaning your fate is not going to solve the problem," she says. "One has to move forward."

Over the past several decades in the U.S., wages have stayed flat or even gone down, while the cost of living has gone up. Economists say that's because jobs went overseas, technology replaced human labor and labor unions have seen their influence decline.
