France's 35-hour work week has plenty of critics who say it has sapped the country of its competitiveness and is tying companies in knots. And to make their case, a leading example is the current state of overtime at French hospitals.

Along with five weeks of annual leave, French employees get time off if they work more than 35 hours in a week. At the Hopital Vaugirard, a public hospital in central Paris, employees have accumulated more than 2 million days off in the past decade.

The twin ports of Los Angeles and Long Beach are the busiest in the nation. They also have some of the dirtiest air, thanks to thousands of cargo trucks that pass through each day.

But this month marks the beginning of a new era, as tighter emissions standards go into effect.

'100 Percent Clean Energy'

A common trope in environmental stories is to put things in terms of jobs vs. the environment. But that's not what happened in the case of the ports.

The dramatic Costa Concordia accident off the coast of Italy is calling attention to the regulation of the cruise line industry. Experts say there are plenty of rules, but enforcement can be spotty.

Some of the survivors of last week's disaster described the rescue effort as chaotic and disorganized. The crew had not yet conducted a required emergency drill during the cruise.

President Obama is feeling election-year pressure on the pending decision over the Keystone XL pipeline. Republicans say the Canadian project would provide the U.S. with oil and new jobs, but environmentalists want him to block it. They say Alberta's oil sands generate more greenhouse gases than other kinds of oil, and Americans must not become dependent on such a dirty source of energy. But it may already be too late to change that.

Old mattresses are among the worst kinds of household waste: Most recycling companies won't touch them, and landfills would rather not. But a new business in Nashville that started as a college project hopes to move mattress recycling into the mainstream — and employ former convicts in the process.

Airs Tuesday, January 17 at 10:00 p.m.  Like many jazz musicians before her, violinist Regina Carter mined her African cultural inheritance through music. Hers is a postmodern approach; her latest record, Reverse Thread, is as likely to source from field recordings of Ugandan Jews as from contemporary Afropop and beyond. It's also delightfully easygoing, intricate yet breezy. Carter and her unique band — featuring kora (West African harp) and accordion — are the first act at the main Fort Stage

Now that Tim Tebow is out of hearts and minds, and we can actually turn our attention to other things, let us go clear to the other side of the world. There, a short while ago, while preparing for the Australian Open, Serena Williams said: "I don't love tennis today, but ... I've actually never liked sports."

While her confession might have surprised some, I suspect that even more were irritated, actually angered, that an athlete — a great champion! — could utter such blasphemy.

There's a controversy brewing in India over an invitation extended to Booker Prize-winning novelist Salman Rushdie by the organizers of the Jaipur Literary Festival.

Rushdie, the author of Midnight's Children, angered Muslims with his 1988 novel Satanic Verses. The novel, which many Muslims say insults the Prophet Muhammad, led to Iran's Ayatollah Ruhollah Khomeini declaring a fatwa against Rushdie. The writer spent much of the next few years in hiding.

Mark told you earlier that Wikipedia is going black for 24 hours beginning at midnight tonight. While Wikipedia's reason for shutting down is to protest anti-piracy legislation making its way through the United States Congress, another interesting question is going to be what happens to all those web surfers seeking answers to can't-wait questions?
