'Stayin' Alive' has near-perfect rhythm to help jump-start heart
CHICAGO, Illinois (AP) -- "Stayin' Alive" might be more true to its name than the Bee Gees ever could have guessed: At 103 beats per minute, the old disco song has almost the perfect rhythm to help jump-start a stopped heart.
In a small but intriguing study from the University of Illinois medical school, doctors and students maintained close to the ideal number of chest compressions doing CPR while listening to the catchy, sung-in-falsetto tune from the 1977 movie "Saturday Night Fever."
The American Heart Association recommends 100 chest compressions per minute, far more than most people realize, study author Dr. David Matlock of the school's Peoria, Illinois, campus said Thursday.
And while CPR can triple cardiac arrest survival rates when properly performed, many people hesitate to do it because they're not sure about keeping the proper rhythm, Matlock said.
He found that "Stayin' Alive," which has a way of getting stuck in your head anyway, can help with that.
His study involved 15 students and doctors and had two parts. First they did CPR on mannequins while listening to the song on iPods. They were asked to time chest compressions with the song's beat.
Five weeks later, they did the same drill without the music but were told to think of the song while doing compressions.

The average number of compressions the first time was 109 per minute; the second time it was 113. That's more than recommended, but Matlock said that when it comes to trying to revive a stopped heart, a few extra compressions per minute is better than too few.
"It drove them and motivated them to keep up the rate, which is the most important thing," he said.
The study showed the song helped people who already know how to do CPR, and the results were promising enough to warrant larger, more definitive studies with real patients or untrained people, Matlock said.

EPA slashes lead limit in air by 90 percent
WASHINGTON (AP) -- The Environmental Protection Agency is slashing the amount of lead allowed in the nation's air by 90 percent.
EPA officials, who were under a federal court order to set a new health standard for lead by midnight Wednesday, said the new limit would better protect health, especially children's. Exposure to even low levels of lead early in life can affect learning, IQ and memory.
"Our nation's air is cleaner today than just a generation ago, and last night I built upon this progress by signing the strongest air quality standards for lead in our nation's history," Stephen Johnson, the EPA administrator, said Thursday. "Thanks to this stronger standard, EPA will protect my children from remaining sources of airborne lead."
The new limit -- 0.15 micrograms per cubic meter -- is the first update to the lead standard since 1978, when it helped phase out leaded gasoline. It is ten times lower than the current standard, which was 1.5 micrograms per cubic meter.

EPA: Lead in the air
It is also more stringent than the level recommended in May by the agency's scientific advisers. In contrast, the Bush administration did not follow its own staff's advice or its science advisers when it set new health standards for smog and soot that were less stringent than recommended.
Environmentalists hailed the move, but said that the agency will have to boost monitoring to ensure that the standard is met.
"We commend EPA for taking a giant step in the right direction, but they need to greatly expand the lead monitoring network if they hope to enforce this standard," said Dr. Gina Solomon, a senior scientist with the Natural Resource Defense Council.

Study: Google does a brain good
(CNN) -- Can Google make you smarter? Is the more you Yahoo, the better? A new study suggests that searching online could be beneficial for the brain.
A study at the University of California, Los Angeles, measured brain activity of older adults as they searched the Web.
"There's so much interest in exercising our minds as we age," said the researcher, Dr. Gary Small, a professor at the Semel Institute for Neuroscience and Human Behavior at UCLA. "One result of this study is that these technologies are not all bad. They may be good in keeping our brains active."
To study what brains look like when people are searching the Internet, Small recruited two groups of people: one that had minimal computer experience and another that was Web savvy.
Members of the technologically advanced group had more than twice the neural activation than their less experienced counterparts while searching online. Activity occurred in the region of the brain that controls decision-making and complex reasoning, according to Small's study, which appears in the American Journal of Geriatric Psychiatry.
Small said he can't pinpoint why there was more brain activity in the experienced users.
"The way I theorized is that when we are confronted with new mental challenges, we don't know how to deal with it," he said. "We don't engage neural circuits. Once we figure out a strategy, we engage those circuits. "
In the study, 24 people were divided into the two groups, who were similar in age ranging from 55 to 78 years old, sex and educational achievement. Their only difference was their technological experience.
The number of people in the study was small, "but adequate to see a difference between the groups. It was so significantly different," Small said.
