(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

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

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...

A study by the University of the Americas (Universidad de la Américas Puebla) in Mexico and the Basque Institute for Agricultural Research and Development, Neiker-Tecnalia, highlights the fact that noise pollution has negative effects on songbirds in cities. The field work, carried out in urban parks in the Metropolitan Area of Puebla-Cholula (Mexico), reveals that the green zones most affected by noise have less bird species.  Among the birds better adapted to urban...

Bigger Birds Hit Hard By Human Noise

Large birds with low-frequency songs are less likely to nest near noisy sites A growing body of evidence shows that man-made noise is bad for birds, but some species are harder hit than others – particularly bigger birds with low-frequency songs, finds a new study. "Bigger birds sing at frequencies that are more easily masked by the low frequencies typical of human noise pollution," said lead author Clinton Francis of the National Evolutionary Synthesis Center in Durham, North...

  • A 'bachelor seal'; a young male seal which is prevented from mating by its herd's older males (mated bulls defending their territory).
This comes from the Russian word for 'bachelors.'
