If you thought the presidential primaries were extraordinarily negative, now there's statistical evidence that you were right.

A new analysis of TV ads finds that 70 percent of the messages were negative — a trend spearheaded by the heavily financed superPACs supporting the candidates. At this point in the 2008 election, 91 percent of TV ads were positive.

A new study has some reassuring news about how fast Greenland's glaciers are melting away.

Greenland's glaciers hold enough water to raise sea level by 20 feet, and they are melting as the planet warms, so there's a lot at stake.

A few years ago, the Jakobshavn glacier in Greenland really caught people's attention. In short order, this slow-moving stream of ice suddenly doubled its speed. It started dumping a whole lot more ice into the Atlantic. Other glaciers also sped up.

It's still too early to predict whether the 2012 corn harvest will set a record, but many corn farmers say the prognosis for a bumper crop is looking pretty good right now.

Among users of bike-sharing programs, like Capital Bikeshare in Washington, D.C., the problem is obvious.

To many people in the Bay Area, the city of Burlingame is just a city straddling the 101, just south of San Francisco International Airport. As you drive by, you might see industrial warehouses and business parks- nothing too distinctive. 

Daniel Chong, a California college senior, was forgotten in a federal holding cell without food or water for five days.

Today, he told All Things Considered's Audie Cornish that the five days tested his sanity and his resolve to live.

"I didn't stay sane," Chong said. "Eventually, by the second or third night ... I went completely insane and was just trying to get a grip on reality, on what's happening to me."

Chong said at one point he thought about using his glasses to cut into his arm and kill himself.
