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...

According to a new study, baleen whales suffered less stress from ship noise after the September 11, 2001 terrorist attacks on the World Trade Center. A study conducted in Canada's Bay of Fundy has revealed that a lull in ship noise after the attacks eased stress on right whales, a type of baleen whale. They analyzed underwater noise levels during a period of reduced ship traffic in the bay after the attacks, and compared the data with levels of stress-related hormone metabolites in the...

(Ivanhoe Newswire) — Deafness affects 2 to 4 of every 1,000 people within the United States alone. A gene known as FGF20, located in a portion of the genome has been associated with inherited deafness in otherwise healthy families, but new clues found in mice may lead to a solution in human deafness. David M. Ornitz, MD, PhD, the Alumni Endowed Professor of Development Biology and his associates Sung-Ho Huh, PhD, and Mark E. Warchol, PhD discovered when they inactivated the FGF20...

Gene Could Helps Scientists Understand Genetic Deafness
2012-01-04 14:17:59

Researchers at Washington University School of Medicine report they have found new clues that may help scientists understand the genetic causes of deafness. The gene FGF20 has been associated with inherited deafness in otherwise healthy families.  The FGF20 gene codes for one member of a family of proteins known as fibroblast growth factors. Members of this family are known to play important and broad roles in embryonic development, tissue maintenance and wound healing. "When we...

High MP3 Player Volume Can Damage Hearing
2011-12-29 09:31:21

Using MP3 players at high volume puts teens at risk for early hearing loss, say TAU researchers Today's ubiquitous MP3 players permit users to listen to crystal-clear tunes at high volume for hours on end – a marked improvement on the days of the Walkman. But according to Tel Aviv University research, these advances have also turned personal listening devices into a serious health hazard, with teenagers as the most at-risk group. One in four teens is in danger of early hearing...

Nine out of 10 city dwellers may have enough harmful noise exposure to risk hearing loss, and most of that exposure comes from leisure activities. Historically, loud workplaces were blamed for harmful noise levels. But researchers at the University of Michigan found that noise from MP3 players and stereo use has eclipsed loud work environments, said Rick Neitzel, assistant professor in the U-M School of Public Health and the Risk Science Center. Robyn Gershon, a professor with the...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
