Actress Anna Kendrick was nominated for an Academy Award for her supporting role in "Up in the Air." Now she stars in the film musical, "Pitch Perfect," in which she plays a college freshman who reluctantly joins the school's illustrious all-female a cappella group. Director Jason Moore is best known for his work on the satirical Broadway musical, "Avenue Q." Film critic David Edelstein has this review of "Pitch Perfect."
A recent study conducted at the University of Pennsylvania identified key molecules involved in forming long-term memories. Experts discuss how this is the latest in a growing field of research on how our bodies regulate our genes, and how this process affects our memories.
President Obama and Mitt Romney are both calling on the U.S. to become less dependent on foreign oil, though their plans differ. Here, workers with Bramwell Petroleum set up a derrick for a new oil well near Spivey, Kan., in March.

The Obama administration has set higher fuel economy standards for cars and promoted alternative energy sources. Here, a Ford Focus electric car is shown during a test drive in San Jose, Calif., in July.
The pressing energy issue in the 2008 presidential campaign was how to reduce carbon emissions and limit global warming. Four years later, the drive for "green energy" has been replaced by a new imperative: the need to end U.S. dependence on foreign oil.
"I will set a national goal of North American energy independence by 2020," Mitt Romney declared during a campaign speech in August. "That means we produce all the energy we use in North America."
He reiterated that goal in the opening minutes of the presidential candidates' debate in Denver this week.
