Illustration of the High Arctic camel on Ellesmere Island during the Pliocene warm period, aboutthree-and-a-half million years ago. The camels lived in a boreal-type forest. The habitat includeslarch trees and the depiction is based on records of plant fossils found at nearby fossil deposits.
Federal Reserve Chairman Ben Bernanke testifies before the Senate Banking Committee in Washington last month. Some analysts wonder if he and other policymakers have kept interest rates too low for too long.
The stock market's long climb from its recession bottom has some people concerned it may be a bubble about to burst — a bubble artificially pumped up by the Federal Reserve's easy-money policy. That's led to calls — even from within the Fed — for an end to the central bank's extraordinary efforts to keep interest rates low.
We turn now to the last U.S. ambassador stationed in Venezuela. Patrick Duddy represented the U.S. first under the Bush administration then later under the Obama administration. He was once expelled from Caracas. Ambassador Duddy is now a visiting senior lecturer at Duke University's Center for International Studies. When we spoke today, I asked him what it was like for him to be an ambassador to Venezuela under Chavez.
Scientists say that understanding how the cocktail party effect works could help people who have trouble deciphering sounds in a noisy environment. Guests make it look easy at a Dolce and Gabbana Lounge party in London in 2010.
Scientists are beginning to understand how people tune in to a single voice in a crowded, noisy room.
This ability, known as the "cocktail party effect," appears to rely on areas of the brain that have completely filtered out unwanted sounds, researchers report in the journal Neuron. So when a person decides to focus on a particular speaker, other speakers "have no representation in those [brain] areas," says Elana Zion Golumbic of Columbia University.
The world often feels full of fading traditions, from drive-in movie theaters to the dying art of good old-fashioned letter writing.
For the British, add brass bands to that list. Traditional brass bands have played an important cultural role in working-class British communities for centuries. But some warn that without funding, they could become a thing of the past.
Take the Grimethorpe Colliery Band in South Yorkshire. The band was originally formed in 1917, and nearly 100 years later, a group of tuba, euphonium and other horn players still bears the band's name.
The death of Venezuelan President Hugo Chavez is an especially tough blow for Cuba, whose feeble state-run economy has been propped up for more than a decade with Venezuelan oil shipments and other subsidies.
The Castro government has declared three days of mourning, calling Chavez "a son" of Cuba, but privately Cubans are quietly fretting about the potential loss of billions in trade and the threat of a new economic crisis.
Economists look at many tea leaves as they try to determine the health of the economy. One of the most important surrounds vehicle sales, and more specifically pickup truck sales, which are tied to the construction industry. And as last month's sales rose 18 percent, the auto industry is betting big on a real estate rebound.
It's arguable that the Ford F-150 is the most important vehicle to come out of Detroit since the Model-T. It's also built where many parts for the old Model-T were made in Dearborn, Mich.
Twenty years ago, theatrical clowns Bill Irwin and David Shiner collaborated on a Broadway show called Fool Moon — a giddy mixture of slapstick, improv and audience participation that proved such a success that it came back to Broadway for two more runs and toured both the U.S. and Europe. Now Irwin and Shiner have put together a new show called Old Hats, and it's been receiving rave reviews off-Broadway.
Irwin and Shiner's rubber-faced, loose-bodied clowning hasn't gotten easier over two decades.
