Americans are suspicious of drones. Reports of the unmanned aerial vehicles' use in war zones have raised concerns about what they might do here at home. For instance, in Seattle earlier this year, a public outcry forced the police department to abandon plans for eye-in-the-sky UAV helicopters.

It's one of the smallest law enforcement agencies in the federal government, but the Bureau of Alcohol, Tobacco, Firearms and Explosives has sure had a busy couple of weeks.

Dozens of its agents raced to Boston, where they analyzed bombs left near the finish line of the marathon. Others went south to Texas, where a fertilizer plant exploded under mysterious circumstances. Members of the ATF's national response team are still on the scene in tiny West, Texas, sifting through rubble at the blast site, near a crater that's 93 feet wide.

Soccer isn't just a sport in Brazil, it's a religion, and the main temple is the Maracana in Rio de Janeiro.

The venue is not only the biggest stadium in Brazil but the biggest in South America. Over the weekend, the newly renovated complex reopened to great fanfare, with stirring musical numbers, a light show and dignitaries including Brazil's president.

The headlines in the local media, however, focused not on the fanfare but on the many problems, from flooding in the VIP area to malfunctioning seats and turnstiles. The stadium was also four months late reopening.

Smoking has its risks, but in California higher prices for health insurance probably won't be among them.

The federal health law allows states to charge smokers up to 50 percent more for a health plan, but a bill moving forward in the California Legislature would prevent that from happening.

The Affordable Care Act is supposed to remove discrimination in the pricing of health insurance for things like gender and medical condition. Critics say a tobacco surcharge creates a new category of discrimination against smokers.

Even when people think they're buckling down, studies show the average office worker wastes over a third of the day. There's Facebook, of course, and the email from a friend with a YouTube link. After all that, is it time to go get coffee?

Worker pay is the most expensive line item in the budget for most businesses, which means billions of dollars are going to waste.

But here's the silver lining: It turns out lack of productivity presents a big business opportunity.

Joe Hruska is pretty blunt about how much work anyone does in a typical day.

Ask most folks who came up with the theory of evolution, and they'll tell you it was Charles Darwin.

In fact, Alfred Russel Wallace, another British naturalist, was a co-discoverer of the theory — though Darwin has gotten most of the credit. Wallace died 100 years ago this year.

NASA is calling it "The Rose." By any other name, it's a mammoth storm on Saturn's north pole. Its eye spans an estimated 1,250 miles — 20 times the size of an average hurricane's eye on Earth. Winds in the Saturn storm's eye wall are believed to be four times as fast.

The stunning image of the spinning vortex was given "false colors" to emphasize low clouds (in red) versus high clouds (in green). NASA estimates that the clouds at the outer edge are moving at up to 330 miles per hour.

Cargo Plane Crash In Afghanistan Kills 7

Apr 29, 2013

A civilian cargo plane crashed in Afghanistan, killing all seven crew members, the U.S. military said Monday.

NPR's Tom Bowman is reporting on it for our Newscast team. He says:

"Officials say the crash killed all seven crew members. And there is no word yet on their nationalities.

"Emergency responders are still on the scene of the crash, at the sprawling base north of Kabul. Officials are still trying to determine the reason for the crash but say there's no indication of hostile fire.

There are still relatively few women in tech. Maria Klawe wants to change that. As president of Harvey Mudd College, a science and engineering school in Southern California, she's had stunning success getting more women involved in computing.

About 40 medical personnel have arrived at the U.S. detention center at Guantanamo Bay amid an increase in the number of hunger strikers at the facility.
