Removing any doubt about whether you're allowed to puff away on an electronic cigarette while airborne, the Department of Transportation has explicitly banned vaping on commercial flights.

At first glance, the front-page headlines in China's Southern Metropolis Daily on Feb. 20 looked like normal fare: coverage of a speech by President Xi Jinping and a politician's funeral.

But read vertically, and there's a message that seems to criticize a government crackdown on the media.

NPR's Anthony Kuhn in Beijing reports that an editor at the major tabloid has been fired for allegedly sneaking in the subversive message, and walks us through what it says.

Havana will meet the Rolling Stones later this month.

The band has announced they'll play a free open-air concert in the Cuban capital on March 25.

That will make them "the most famous act to play Cuba since its 1959 revolution," the Associated Press reports.

Less than four months after it started accepting Syrian refugees, Canada says it has reached its goal of bringing in 25,000 people who have fled the raging civil war.

As thousands of migrants wait to cross the border from Greece into Macedonia, the U.N. warns that Europe is "on the cusp of a largely self-induced humanitarian crisis."

Macedonian authorities closed the Idomeni border crossing Monday, sparking clashes with the frustrated migrants who want to continue their journey north. Guards fired tear gas and rubber bullets at the crowd, the BBC reports.

Syria's cessation of hostilities is largely holding on its third day, even as the main opposition umbrella group accuses the Syrian regime of violations.

Riad Hijab, the opposition's general coordinator, wrote a letter to the U.N. Secretary-General detailing the alleged breaches of the truce, which was brokered by the U.S. and Russia. The letter reads, in part:

Final results are beginning to trickle in from Iran's parliamentary elections, and these returns show major gains for the country's moderate camp.

NPR's Peter Kenyon says reformist parliamentary candidates swept the seats in Iran's capital, Tehran. "All hardline incumbents in the capital lost their seats," Peter reports, though he says conservatives fared better in other provinces.

The Cleveland Clinic says it has performed the first uterus transplant in the United States.

This opens up another possible path to parenthood besides surrogacy or adoption for U.S. women who do not have a uterus, or who have a uterus that does not function.

A "cessation of hostilities" has come into effect in Syria at midnight local time (5 p.m. EST).

The temporary pause in fighting was brokered by the U.S. and Russia, and is meant to be a confidence-building measure to jump-start peace talks between the warring parties. It includes the Syrian government and the main opposition bloc.

A major global assessment of pollinators is raising concerns about the future of the planet's food supply.

A U.N.-sponsored report drawing on about 3,000 scientific papers concludes that about 40 percent of invertebrate pollinator species (such as bees and butterflies) are facing extinction. Vertebrate pollinators (such as bats and birds) are somewhat better off by comparison — 16 percent are threatened with extinction, "with a trend towards more extinctions," the researchers say.
