It's not that there aren't economic disruptions from the earthquake in Japan.
Two of Japan's major industries — electronics and auto manufacturing — both had some factories in the region where the earthquake hit.
Shinichi Sato works for Hino Motors, which makes trucks and buses in Japan. Hino also puts together axles for some Toyota vehicles. Their operations were shut down all last week, and the beginning of this week.
"This is not only Hino," Sato says. "All the automobile companies" are in the same situation.
A newly excavated site in central Texas contains evidence that the first human settlers in the Lone Star state arrived more than 15,000 years ago. That's more than 2,000 years earlier than scientists originally thought.
The discovery should help end a controversy about whether a culture known as Clovis was the first to settle in the Americas. The site is on Buttermilk Creek, north of Austin, and there are plenty of good reasons why our ancient ancestors would have camped here.
As radioactive contamination from the Fukushima Dai-ichi nuclear power plant spreads, a global network of sensors is tracking it across oceans and continents. The network was originally set up to detect nuclear weapons testing, but scientists now hope it can tell them more about the accident.
The Comprehensive Test Ban Treaty Organization began setting up its monitoring stations about a decade ago, with the eventual goal of enforcing a worldwide ban on nuclear weapons tests.
Youth violence rates around the country have been decreasing in recent years, but violent crimes are still most concentrated in poorer, urban neighborhoods. Experts say kids who grow up in dangerous areas are more likely to become targets.
In Chicago, a program called CeaseFire is working to curb violence by helping at-risk youth find employment and patrolling the streets to stop crimes before they happen.
The military objective of the Libya campaign is to protect civilians, but the U.S. and other governments have a larger goal: They want Libyan leader Moammar Gadhafi out of power. And if airstrikes and 1,000 or so rebel fighters cannot bring down the regime, the anti-Gadhafi effort will depend on financial sanctions.
