Syrians demonstrate against the regime after Friday prayers in the north Syrian city of Idlib on Friday. Thousands of Syrians rallied to demand Bashar al-Assad's ouster, as the embattled president's forces unleashed their heaviest pounding yet of Homs in a brutal bid to crush dissent, monitors said.
The offensive started on the city of Homs, where neighborhoods that have seen some of the largest protests and armed resistance to the government are now under constant fire from tanks, rockets and mortars.
Homs is in central Syria, and it is thought that if the regime lost it to the opposition, that would cut the country in half. The offensive continued in the city of Zabadani, a mountain resort town just outside of Syria's capital of Damascus.
Rick Santorum and Mitt Romney took the stage in a January presidential debate in Florida. They'll meet again Wednesday night in Arizona, which holds its primary on Feb. 28, the same day as the crucial Michigan contest.
The rise of Rick Santorum in the race for the Republican presidential nomination hasn't exactly gone unnoticed by rival Mitt Romney or his friends. Turn on a TV in Michigan this weekend, and chances are you won't have to wait long to see an ad attacking the former Pennsylvania senator.
"America is drowning in national debt," a narrator intones in one ad, a product of Romney's campaign. "Yet Rick Santorum supported billions in earmarks."
Senegal's capital of Dakar remains jittery, with the youth and the riot police locked in running street battles.
The police are using teargas, rubber bullets and water cannon spray to chase away angry opposition demonstrators, including rappers from the Y'en a Marre movement. Their name means "We're Fed Up, Enough is Enough."
This past week, a planned overnight sleep-in protest was broken up by the security forces. Founding member and rapper, Djily Baghdad, blames Abdoulaye Wade for the ban, the crackdown and for overstaying his welcome as president of Senegal.
Not known as a hotbed of experimentation, the world of publishing has been slow to embrace the transition from print to e-books. This past week in New York, however, the Tools of Change digital publishing conference attracted entrepreneurs and innovators who are more excited by, rather than afraid of, the future.
It was the kind of crowd where some were more inclined to say "Steal my book!" than to argue over what that e-book should cost. These are people who see digital publishing not as a threat, but as an opportunity.
Do-it-yourselfers have made everything from bamboo bicycles to 3-D printers, but nothing as ambitious as what's happening on a farm in northwest Missouri where tractors and other industrial machines are being made from scratch.
Marcin Jakubowski earned a Ph.D. in physics, and his doctoral thesis deals with velocity turbulence and zonal flow detection, whatever that is. But when Jakubowski graduated in 2004, he wanted nothing to do with physics or academia.
It was one of the more surreal photo ops this week: Iran's president Mahmoud Ahmadinejad, live on Iranian TV, visiting a nuclear reactor. Ahmadinejad trumpeted his country's nuclear progress, but denied, once again, that Iran is pursuing nuclear weapons.
In Washington, officials weren't buying it.
They rushed to repeat the official U.S. line — a line President Obama himself is fond of delivering.
"Let there be no doubt: America is determined to prevent Iran from getting a nuclear weapon, and I will take no options off the table to achieve that goal," he said.
One of the most talked about personalities on the Republican presidential campaign trail — Callista Gingrich — rarely says a word.
That changed at the Conservative Political Action Committee earlier this month when she spent three minutes introducing her husband. Politico quipped it was the "longest most people have ever heard her speak."
In this presidential campaign, as in the past, the candidates' spouses play a very particular role.
"Loose lips sink ships." "Only you can prevent forest fires." "A mind is a terrible thing to waste." "Take a bite out of crime." Sound familiar?
Those tag lines are just a few of the many ads created by the Ad Council, a nonprofit organization that was founded in the 1940s by the leaders of the advertising industry and President Franklin Roosevelt.
