The act that required the federal minimum wage to be raised to $7.25 an hour by 2010 eased into law as a rider to a congressional omnibus spending bill in 2007.
The level of ozone-depleting chemicals in the atmosphere is falling, mostly because of reductions in one solvent, meaning further cuts can occur only if emissions of other chemicals are lowered, researchers say. "We have made progress, but we're not out of the woods yet," said Stephen A. Montzka of the National Oceanic and Atmospheric Administration.
Dr. Shanker Mukherjee has seen where few have seen before. Without setting foot in outer space, shrinking to the size of a microbe or dabbling in science fiction, the Easton, Pa., gastroenterologist has taken some fantastic journeys. Dr. Mukherjee uses a new diagnostic technique known as endoscopic ultrasound, or EUS, which allows doctors to see into areas of the body that were until recently nearly impossible to image.
A team of researchers has come up with an explanation for something many test takers, public speakers and performers already know: Memory can fail under pressure. The scientists at the University of California at Irvine showed that an elevated level of a stress hormone hinders the ability of rats to find their way back to a hidden target. The study was to be published Thursday in the journal Nature.
Researchers believe they have an answer to the world's mounting energy problem, and it's not the $10 billion experimental fusion reactor community leaders in the Aiken-Augusta area want for Savannah River Site. Their proposal: a cheaper and much smaller fusion machine they claim will produce enough electricity to power a city the size of Augusta for just a few dollars a day. Operating the reactor would not involve the hazards or yield the radioactive waste normally associated with nuclear power, they say.
It was one of those chance-in-a-million things. Not long after she was raped, an Indiana woman thought she spotted her assailant on the street. Police arrested the man, took his blood and sent it to a crime lab for DNA analysis. Robert Flowers said he hadn't committed the crime, and lab results showed he was telling the truth: His DNA didn't match the rapist's. But it came so close, the laboratory just had to ask - could Robert Flowers have a brother? He could, and he did. And, eventually, Robert's look-alike brother was convicted of the rape.
Four states are vowing to fight the federal government in a bid to preserve state measures that guarantee workers the right to secret ballots in union elections.
NEW YORK -- Like many poets, Kay Ryan values time more than money - a preference that has left her savings account lean.
A Mozart sonata may lift the soul, but it won't make listeners any smarter, according to two studies that challenge previous research and popular belief about the effect of music on intelligence.\r
Race relations As anthropologists learn more about how genes are spread among humans, they are starting to believe that there is no such thing as race. People around the world are more similar genetically than they are different, according to Alan R. Templeton, an evolutionary and population biologist at Washington University in St. Louis. All people share about 85 percent of the same genes, he reported in the journal American Anthropologist. That is not enough of a difference, he says, to separate people by race.
