Voters in southern Arizona's 8th Congressional District are deciding who will fill the seat formerly held by Rep. Gabrielle Giffords. The Democrat resigned in January, a year after she was badly injured by a gunman at a district event in Tucson.

Giffords' resignation set in motion a special election to serve out the rest of her two-year term. Giffords' former district director, Ron Barber, won the Democratic nomination uncontested. Jesse Kelly easily beat three opponents in the Republican primary.

One of the big movie blockbusters this year isn't a film, but a business deal.

The Chinese company Wanda, one of that country's leading cinema owners, is buying AMC Entertainment, North America's second-largest movie theater company, for $2.6 billion.

When the agreement was announced in China this week, it did not make a lot of sense at first glance. At least for the buyer.

AMC is loaded with some $2 billion in debt, and movie theater attendance in North America was down 4 percent last year.

Becky Cole was eight months pregnant with her fourth child when she collapsed against the bathroom door. It was January 2011 in the Seattle suburb of Woodinville.

Nurses are the backbone of the hospital — just ask pretty much any doctor or patient. But a new poll conducted by NPR, the Robert Wood Johnson Foundation and the Harvard School of Public Health finds 34 percent of patients hospitalized for at least one night in the past year said "nurses weren't available when needed or didn't respond quickly to requests for help."

Since nurses provide most of the patient care in hospitals, we were surprised at the findings. We wanted to find out more. We wanted to know what was going on from nurses themselves. So we put a call-out on Facebook.

Russia is still the world's largest producer of oil and gas, but growth has stalled and to get to new supplies requires going to a very difficult place — the Arctic.

"If you want to be in this business in 2020, 2025, you must think about the Arctic," says Konstantin Simonov, head of the National Energy Security Fund in Moscow.
