An unusual terrorism case started in Nigeria late last week. Prosecutors in the capital city of Abuja accused two local men of being members of al-Qaida in the Arabian Peninsula, or AQAP. They were charged with accepting thousands of dollars from the group to recruit potential terrorists inside Nigeria and then send them to Yemen. Olaniyi Lawal, 31, and Luqman Babatunde, 30, have pleaded not guilty.
Most Americans use electricity, gas or oil to heat and cool their homes. But the small city of Brainerd, Minn., is turning to something a bit less conventional: the sewer.
As it turns out, a sewer — the place where a city's hot showers, dishwashing water and organic matter end up — is a pretty warm place. That heat can generate energy — meaning a city's sewer system can hold tremendous potential for heating and cooling.
It's just that unexpected energy source that Brainerd hopes to exploit.
This week, President Obama signed a law banning synthetic marijuana and other synthetic drugs. Dozens of states and local governments have already tried to outlaw fake marijuana, which has been blamed for hundreds of emergency room visits and a handful of fatalities.
But the bans have proved largely ineffective, and there are fears that the federal law won't be any different.
Synthetic marijuana looks a bit like dried grass clippings. It's readily available on the Internet and in convenience stores and smoke shops, where it's sold as herbal incense or potpourri.
Maxima Guerrero and Daniel Rodriguez canvass for votes in Phoenix. Rodriguez moved to the U.S. with his mother when he was a child, and is undocumented. "The best thing I can do now," he says, "is organize those that can [vote], and make them vote for me."
For years, Maricopa County, Ariz., has been ground zero in the debate over immigration.
On one hand, the massive county, which includes the state capital of Phoenix, has a growing Latino population. On the other, it's home to publicity savvy Sheriff Joe Arpaio, who has made his name by strictly enforcing, some say overstepping, immigration laws.
