Unemployment: State by State

Jobless Rate Rose in 30 States inJanuary, Five Hit Records

Unemployment rose in most states in January--even breaking records in several states, according to government data released Wednesday.Joblessness in five states--California (12.5 percent), South Carolina (12.6 percent), Florida (11.9 percent), Georgia (10.4 percent), and North Carolina (11.1 percent)--hit a record high. The District of Columbia, at 12.0 percent, also reached a record high.
In all, 30 states and the District of Columbia saw their rates increase in January over the previous month. Nine states reported a decrease and 11 states had no change in their unemployment, according to the Labor Department.
Fewer states showed an increase in their unemployment rate in January compared with December, when 43 states showed an increase in jobless rates.
=========================================
"It shows that the labor market is virtually frozen," said Nick Colas, chief market strategist at the ConvergEx Group. Although the data is from January, he said that "there has not been any dramatic change in these past six weeks."
The national unemployment rate was at 9.7 percent in January, down from 10 percent in December 2009. The unemployment rate remained at 9.7 percent in February.
Michigan, again, had the highest jobless rate in the nation, though it eased to 14.3 percent from 14.5 percent in December. Michigan's unemployment rate has hovered over 14 percent since July 2009.
"Michigan's unemployment rate fell slightly, as typical January auto industry job cuts did not occur in January 2010," said Rick Waclawek, director of Michigan's Bureau of Labor Market Information and Strategic Initiatives in a statement. "Also, jobs in a number of Michigan industry sectors, including manufacturing, have stabilized since the summer of 2009."
Behind Michigan, Nevada had the second highest jobless rate in the country with 13 percent, followed by Rhode Island (12.7 percent), South Carolina (12.6 percent), and California (12.5 percent).
North Dakota again had the lowest jobless rate in country at 4.2 percent in January, followed by Nebraska (4.6 percent) and South Dakota (4.8 percent).
Separately on Tuesday, the Bureau of Labor Statistics reported a sharp increase in job openings in January. There were 2.7 million job openings in that month, up 7.6 percent from December. That was the highest number of openings since February 2009.

Nasca

Spirits in the Sand

The ancient Nasca lines of Peru shed their secrets.

From the air, the lines etched in the floor of the desert were hard to see, like drawings left in the sun too long. As our pilot cut tight turns over a desert plateau in southern Peru, north of the town of Nasca, I could just make out a succession of beautifully crafted figures.
"Orca!" shouted Johny Isla, a Peruvian archaeologist, over the roar of the engine. He pointed down at the form of a killer whale. "¡Mono!" he said moments later, when the famous Nasca monkey came into view. “¡Colibrí!” The hummingbird.

Since they became widely known in the late 1920s, when commercial air travel was introduced between Lima and the southern Peruvian city of Arequipa, the mysterious desert drawings known as the Nasca lines have puzzled archaeologists, anthropologists, and anyone fascinated by ancient cultures in the Americas. For just as long, waves of scientists—and amateurs—have inflicted various interpretations on the lines, as if they were the world's largest set of Rorschach inkblots. At one time or another, they have been explained as Inca roads, irrigation plans, images to be appreciated from primitive hot-air balloons, and, most laughably, landing strips for alien spacecraft.
After World War II a German-born teacher named Maria Reiche made the first formal surveys of the lines and figures—called geoglyphs—outside Nasca and the nearby town of Palpa. For half a century, until her death in 1998, Reiche played a critically important role in conserving the geoglyphs. But her own preferred theory—that the lines represented settings on an astronomical calendar—has also been largely discredited. The ferocity with which she protected the lines from outsiders has been adopted by their caretakers today, so that even scientists have a hard time gaining access to the most famous animal figures on the plain, or pampa, immediately northwest of Nasca.
Since 1997, however, a large Peruvian-German research collaboration has been under way near the town of Palpa, farther to the north. Directed by Isla and Markus Reindel of the German Archaeological Institute, the Nasca-Palpa Project has mounted a systematic, multidisciplinary study of the ancient people of the region, starting with where and how the Nas ca lived, why they disappeared, and what was the meaning of the strange designs they left behind in the desert sand.
As our plane banked into another turn, Isla, a native of the highlands who works at the Andean Institute of Archaeological Studies, kept his broad, high-cheeked face pressed to the window. "Trapezoid!" he shouted, pointing out a huge geometrical clearing looming into sight. "Platform!" he added, gesturing with his finger. "Platform!"
Platform? He was pointing at a small heap of stones at one end of the trapezoid. If Isla and his colleagues are right, such unprepossessing structures may hold a key to understanding the true purpose of the Nasca lines. The story begins, and ends, with water.
The coastal region of southern Peru and northern Chile is one of the driest places on Earth. In the small, protected basin where the Nasca culture arose, ten rivers descend from the Andes, to the east, most of them dry at least part of the year. These ten fragile ribbons of green, surrounded by a thousand shades of brown, offered a fertile hot spot for the emergence of an early civilization, much as the Nile Delta or the rivers of Mesopotamia did. "It was the perfect place for human settlement, because it had water," says geographer Bernhard Eitel, a member of the Nasca-Palpa Project. "But it was a high-risk environment—a very high-risk environment."

NASA: Quake Shifted Earth's Axis, Shortened Day

NASA: Quake Shifted Earth's Axis, Shortened Day

Updated: 4 hours 33 minutes ago

(March 1) -- Apart from claiming the lives of hundreds of people and wreaking enormous property damage, Chile's massive earthquake has likely altered the distribution of the Earth's overall mass, scientists from NASA say.

As a result, the length of a day is now a little shorter than it was before Saturday's magnitude 8.8 earthquake. 

"The length of the day should have gotten shorter by 1.26 microseconds [millionths of a second]," Richard Gross, a geophysicist at NASA's Jet Propulsion Laboratory, told Bloomberg. "The axis about which the Earth's mass is balanced should have moved by 2.7 milliarcseconds [about 8 centimeters or 3 inches]."

The speed that the Earth rotates also increased slightly in 2004 following the earthquake that struck off the coast of Sumatra, Indonesia. That 9.1 earthquake shortened the length of an Earth day by 6.8 microseconds, scientists say.

The reason is that sudden changes in the dimensions of the Earth's tectonic plates, like those experienced in the earthquakes in Chile and Indonesia, can alter the velocity. 

David Kerridge, the head of Earth hazards and systems at the British Geological Survey in Edinburgh, likened the change in rotation speed to what happens when a figure skater draws her arms in close to her body while spinning. "As she pulls her arms in," Kerridge told Bloomberg, "she gets faster and faster. It's the same idea with the Earth going around: If you change the distribution of mass, the rotation rate changes."
