Physical activity does more than tone up the heart and reduce the risk of heart attacks. Moderate physical activity -- aerobic as well as pumping iron -- fortifies various segments of the cardiovascular system.
Researchers say that taking images of the heart using radioactive material after a traditional treadmill test may better identify those who are able to exercise for long periods of time, but are still at increased risk for heart attack, death, or the need for bypass surgery or balloon angioplasty.
Hitching a ride on a comet may be like latching onto a bus's tailpipe. A recent Arizona State University study, published in the February 10 issue of The Astrophysical Journal, found that comet gas tails, previously thought to be mostly water, actually contain high concentrations of ionized carbon monoxide .
A measurement technique originally designed for studying interactions within molecules of DNA has been used to examine muscle movement at the molecular level, says a University of Illinois researcher who developed the procedure.
