Interior Secretary Ken Salazar speaks at the dedication for the Southwest's first urban wildlife refuge on the southern edge of Albuquerque, N.M., on Sept. 27, 2012. Salazar has announced that he'll leave his post in late March and return to Colorado.
The Department of the Interior is huge — more than 70,000 employees manage a half-billion acres of public land, mostly in the West. The department does everything from operate national parks to administer Native American social programs and manage wild horses.
Vegetation like the kind growing here at Michigan State University's Kellogg Biological Station could one day be used to feed small biofuel refineries spread throughout the Midwest.
This map shows the potential biomass collection within 10 states. Each circle represents an area of about 7,800 square miles, which could produce about 23 million gallons of ethanol per year. A gigagram, or Gg, is about 1,100 tons.
Millions of acres of marginal farmland in the Midwest — land that isn't in good enough condition to grow crops — could be used to produce liquid fuels made from plant material, according to a study in Nature. And those biofuels could, in theory, provide about 25 percent of the advanced biofuels required by a 2007 federal law.
But there are many ifs and buts about this study — and, in fact, about the future of advanced biofuels.
Lucas Codognolla, 22, receives his license after qualifying for it under President Obama's federal immigration policy, which allows some young immigrants who are in the country illegally to stay in the U.S. for at least two years.

The 22-year-old's family emigrated from Brazil when was just 9. When he turned 16 and wanted to get his driver's license, his parents sat him down and told him the truth: He was in the country illegally.
Initially, he lied to his friends about why he couldn't drive, he says. But then, as he got older, driving simply became necessary.

As NPR's Sean Carberry reports, the attack began with a suicide bombing, then five militants tried to storm the compound.
