Heart attack survivors who live about 100 meters (328 feet) or less from a major U.S. roadway face increased risk of death from all causes, according to new research in the American Heart Association's journal Circulation. In the Determinants of MI Onset Study of 3,547 heart attack survivors (average age 62), researchers found: Those living less than 100 meters (328 feet) from the roadway have a 27 percent increased risks of dying over 10 years than those living at least 1,000 meters...

A new study published in the Proceedings of the Royal Society B has found that human noise like traffic can have ripple effects on plants. Lead author Clinton Francis of the National Evolutionary Synthesis Center (NESCent) in Durham, North Carolina, said the consequences of noise could last for decades, even after the source of the noise goes away. Previous studies found that some animals increase in numbers near noisy sites, while others decline, but the results of the new study found...

Blue whale vocal behavior is affected by man-made noise, even when that noise does not overlap the frequencies the whales use for communication, according to new research published Feb. 29 in the open access journal PLoS ONE. The whales were less likely to emit calls when mid-frequency sonar was present, but were more likely to do so when ship sounds were nearby, the researchers report. The study was conducted in the Pacific Ocean off the coast of Southern California by Mariana Melcon and...

Hearing loss has been linked with a variety of medical, social and cognitive ills, including dementia. However, a new study led by a Johns Hopkins researcher suggests that hearing loss may also be a risk factor for another huge public health problem: falls. The finding could help researchers develop new ways to prevent falls, especially in the elderly, and their resulting injuries that generate billions in health care costs in the United States each year, by some estimates. To determine...

Sparrows, blackbirds and the great tit are all birds known to sing at a higher pitch (frequency) in urban environments. It was previously believed that these birds sang at higher frequencies in order to escape the lower frequencies noises of the urban environment. Now, researchers at the University of Copenhagen and the University of Aberystwyth have discovered that besides noise, the physical structure of cities also plays a role in altering the birds´ songs. Urban birds sing...
