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.
Fans mourn outside the funeral service for singer Whitney Houston in Newark, N.J., on Saturday. The pop superstar was found dead in a California hotel room a week ago. The cause of death has yet to be determined.
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.
A troubled starlet dies in a helicopter crash off the Irish coast after sending a series of mysterious text messages. Three years later, a hungry young reporter desperate for work takes an assignment to write a quickie celebrity biography of her — but finds complexity and danger.
That seemingly accidental death is the catalyst for the events in Bloodland, a new thriller by Irish author Alan Glynn.
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.
So here's a conundrum for parents. If you have kids, you get told over and over limit their screen time. And you're also told, instead of screen time, get them reading more, which is all well and good, except that these days, many children do their reading on a screen, which raises some interesting questions about how children read today and what direction things are headed in children's book publishing.
