Deafness and seizures result when mysterious protein deleted in mice
Scientists have discovered that mice genetically engineered to lack a particular protein in the brain have profound deafness and seizures. The finding suggests a pathway, they say, for exploring the hereditary causes of deafness and epilepsy in humans. view more (2008-01-25)
Low testosterone levels associated with increased risk of death in men
Men who have a low testosterone level after age 40 may have a higher risk of death over a four-year period than those with normal levels of the hormone. view more (2006-08-15)
Alaska's Columbia Glacier continues on disintegration course
Alaska's rapidly disintegrating Columbia Glacier, which has shrunk in length by 9 miles since 1980, has reached the mid-point of its projected retreat, according to a new University of Colorado at Boulder study. view more (2005-12-08)
'Invisibility cloaks' could break sound barriers
Contrary to earlier predictions, Duke University engineers have found that a three-dimensional sound cloak is possible, at least in theory. view more (2008-01-10)
A sound way to turn heat into electricity
University of Utah physicists developed small devices that turn heat into sound and then into electricity. The technology holds promise for changing waste heat into electricity, harnessing solar energy and cooling computers and radars. view more (2007-06-04)
Help is at hand for noisy orchestra pits
"BEING punched in the back of the neck with a blunt instrument." That`s how William Morton, a retired flautist with the Royal Opera House orchestra in London, describes the blast of sound that assaults the senses of musicians performing in the confined spaces of an orchestra pit. Musicians in these... view more... (2002-02-20)
Exxon Valdez oil found in tidal feeding grounds of ducks, sea otters
Seventeen years after the Exxon Valdez ran aground in Alaska's Prince William Sound, compelling new evidence suggests that remnants of the worst oil spill in U.S. history extend farther into tidal waters than previously thought, increasing the probability that the oil is causing unanticipated long-term harm to wildlife. view more (2006-05-16)
Research tracks whales by listening to sounds
Researchers have developed a new tool to help them study endangered whales - autonomous hydrophones that can be deployed in the ocean to record the unique clicks, pulses and calls of different whale species. view more (2006-01-03)
Noise-Immune Stethoscope Helps Medics Hear Vital Signs in Loud Environments
A new type of stethoscope enables doctors to hear the sounds of the body in extremely loud situations, such as during the transportation of wounded soldiers in Blackhawk helicopters. view more (2006-11-29)
From neolithic bones to carbon fiber - flute-making gets boost from modern science
A combination of modern materials, technology, and venture capital catapults Finnish flute-makers in international music spotlight. Beauty of sound "I was inspired by the delicate sound of the simple bamboo flute and experimented with various materials and techniques to construct a light flute frame," Matti K'¤hönen of Matit Flutebrothers in... view more...

Extreme Winds Rule Exoplanet's Weather
Supersonic winds more than six times faster than those on Jupiter are blasting through the atmosphere of a Jupiter-sized planet 60 light years away, say scientists who've analyzed results from NASA's Spitzer Space Telescope. view more (2007-05-10)
Mystery solved
Answering a question that has lingered for centuries, a team of scientists has proved that chemicals used to treat the wood used in Stradivarius and Guarneri violins are the reasons for the distinct sound produced by the world-famous instruments. view more (2006-11-30)
UVa researchers restore genes in human inner ear cells
Researchers at the University of Virginia Health System have discovered a way to transfer genes, which they hope will restore hearing, into diseased tissue of the human inner ear. view more (2007-06-14)
Sound investment: A new mathematical method provides a better way to analyze noise
Humans have 200 million light receptors in their eyes, 10 to 20 million receptors devoted to smell, but only 8,000 dedicated to sound. view more (2006-07-27)
Earthquake 'memory' could spur aftershocks
Using a novel device that simulates earthquakes in a laboratory setting, a Los Alamos researcher and his colleagues have shown that seismic waves-the sounds radiated from earthquakes-can induce earthquake aftershocks, often long after a quake has subsided. view more (2008-01-04)
Toward world's smallest radio: nano-sized detector turns radio waves into music
Researchers report development of the world's first working radio system that receives radio waves wirelessly and converts them to sound signals through a nano-sized detector made of carbon nanotubes. view more (2007-10-18)
Making sense of the world through a cochlear implant
Scientists at University College London and Imperial College London have shown how the brain makes sense of speech in a noisy environment, such as a pub or in a crowd. The research suggests that various regions of the brain work together to make sense of what it hears, but that when the speech is completely incomprehensible, the brain appears to... view more...
