According to new research, 3.7 million Americans who live at elevations close to high tide could face more frequent flooding because of the sea rise caused by global warming.

The New York Times reports:

The cacophony of hoots being directed at Mitt Romney Wednesday for his poor performances in Alabama and Mississippi primaries is somewhat curious, especially since it was the conventional wisdom as recently as last week that the Deep South was likely to be very tough going for him.

After U.S. troops inadvertently burned Qurans in Afghanistan last month, Afghans staged nationwide riots that left 40 dead and hundreds injured in unrest that lasted days.

In the days since 16 Afghan civilians were shot dead on Sunday, apparently by a lone U.S. soldier, the Afghan reaction has been relatively restrained so far.

Why such different responses? It can seem especially confounding to Americans, who consider the shooting a far graver offense than the Quran burnings.

Listen to the conversations around you — colleagues at the office, customers in the coffeehouse line, those who serve you, those you serve, the people you meet each day. "Give me a tall latte." "Hand me that hammer." "Have a good one."

Notice anything missing? The traditional magic words "please" and "thank you" that many people learn as children appear to be disappearing.

With great power comes not-so-great nicknames. At least, that was the case for some of the most notorious queens and female rulers in history:

Egypt's Cleopatra: "Serpent of the Nile."

Rome's Agrippina: "Atrocious and Ferocious."

England's Mary Tudor: "Bloody Mary."

France's Catherine de Medici: "The Black Queen."

France's Marie Antoinette: "Madame Deficit."

China's Cixi: "The Dragon Empress."

The Pentagon says an Afghan drove a stolen truck onto the airfield of a British base in southern Afghanistan at high speeds until it crashed into a ditch and exploded into flames.

The incident at Camp Bastion happened around the same time that U.S. Secretary of Defense Leon Panetta landed in the country.

"At no point was the Secretary or anyone on the aircraft in any danger from this incident," the International Security Assistance Force said in a statement.

Cooling a person's hands while exercising can make for a better workout, especially for people who hate to exercise because it makes them all hot and sweaty.

This might help the many, many people who have a hard time keeping up with exercise because it's just plain uncomfortable.

Researchers tested the idea with obese women in their 30s and 40s who worked out on a treadmill. The women whose palms were cooled with a device that circulated ice water were able to exercise longer than the women whose palms were exposed to room temperature water.

There's a new record in the Iditarod: A 25 year old has become the youngest musher to win the approximately thousand-mile trans-Alaskan sled dog race.

Dallas Seavey slid into Nome, Alaska, at 7:29 p.m. yesterday with nine dogs, finishing the race in nine days, four hours, 29 minutes and 26 seconds.

"We went into this race with a dog team that I knew had the ability to win the Iditarod," Seavey said in a post-race press conference in Nome. "We spent most of the race building a monster – a dog team that couldn't be stopped."

Rick Santorum won the Alabama and Mississippi primaries last night, despite being outspent by GOP front-runner Mitt Romney. Santorum's wins raise questions about the candidates' ability to connect with the party's base. Host Michel Martin speaks with Mississippi Public Broadcasting's Jeffrey Hess and John Archibald of The Birmingham News.

For this year's South By South West conference, some of Austin's homeless were equipped with mobile Wi-Fi devices and t-shirts inviting attendees to use these hotspots to get online. Reactions have ranged from support, to disbelief, to outrage. Host Michel Martin discusses the ethical implications with a technology reporter and an ethicist.
