APS Podcast Updates Research on Elephant Seismic Communication
Caitlin O'Connell-Rodwell's insight that elephants 'talk' and 'listen' to vocalizations that they send through the ground grew from long hours of observation and experimentation, as well as her own in-depth knowledge of insects that communicate seismically. view more (2009-09-21)
Fruit flies' response to wind offers new window to neural circuits
Try this at home: If fruit flies are buzzing around your kitchen, switch on your hairdryer and aim it at the flies. A gentle stream of air will stop them in their tracks, putting them in prime position for swatting. view more (2009-03-18)
Colas ensures noise doesn't break the sound barrier
Colas, the leading road construction and maintenance group, and its subsidiary, Somaro, a specialist in safety equipment and road signs and signals, in partnership with the Ecole Polytechnique, have developed a new type of noise barrier for roads with an unequalled level of sound absorption. Depending on the configuration, the barrier's... view more... (2004-03-10)
Sound adds speed to visual perception
The traditional view of individual brain areas involved in perception of different sensory stimuli-i.e., one brain region involved in hearing and another involved in seeing-has been thrown into doubt in recent years. view more (2008-08-12)
Plastics suspect in lobster illness
The search for what causes a debilitating shell disease affecting lobsters from Long Island Sound to Maine has led one Marine Biological Laboratory (MBL) visiting scientist to suspect environmental alkyphenols, formed primarily by the breakdown of hard transparent plastics. view more (2008-08-15)
Manatees can probably hear which directions boats approach from
The world is a perilous place for the endangered manatee. While the mammals are at risk from natural threats, human activity also poses a great danger to manatee numbers. view more (2009-06-12)
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)
Sensory feedback during speech: The brain attunes to more than just sound
Using robotics to manipulate the brain's perception of jaw movement while words are spoken, researchers have deepened our understanding of the importance of non-auditory sensory cues in the brain's control of speech. view more (2006-10-10)
Disorder enables extreme sensitivity in piezoelectric materials
A research team working at the National Institute of Standards and Technology (NIST) has found an explanation for the extreme sensitivity to mechanical pressure or voltage of a special class of solid materials called relaxors. view more (2008-05-19)
Carnegie Mellon scientists show brain uses optimal code for sound
Scientists at Carnegie Mellon University have discovered that our ears use the most efficient way to process the sounds we hear, from babbling brooks to wailing babies. view more (2006-02-24)
Pioneering space station experiment keeps reactions in suspense
A revolutionary container-less chemical reactor, pioneered by the space research team at Guigné International Ltd (GIL) in Canada with scientists at the University of Bath, has been installed on the International Space Station. view more (2008-12-12)
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)
Yale researchers find environmental toxins disruptive to hearing in mammals
Yale School of Medicine researchers have new data showing chloride ions are critical to hearing in mammals, which builds on previous research showing a chemical used to keep barnacles off boats might disrupt the balance of these ions in ear cells. view more (2006-04-12)
Promising new metamaterial could transform ultrasound imaging
Using the same principles that help create a guitar's complex tones, researchers at the University of California, Berkeley, have developed a new material that holds promise for revolutionizing the field of ultrasound imaging. view more (2006-06-01)
Aural and visual appreciation of arts
Museum visitors appreciate the direct access to relevant information provided by audio-guided tours of exhibitions using headsets that eliminate the need to leaf through fat catalogs to read about the works of art. Imagine, how much more exciting it would be if exhibits could recognize a visitor's focus of interest and interact with him directly.... view more... (2002-06-26)
Caltech scientists discover mechanism for wind detection in fruit flies
Tiny, lightweight fruit flies need to know when it's windy out so they can steady themselves and avoid being knocked off their feet or blown off course. But how do they figure out that it's time to hunker down? view more (2009-03-13)
Estrogen Controls How the Brain Processes Sound
Scientists at the University of Rochester have discovered that the hormone estrogen plays a pivotal role in how the brain processes sounds. view more (2009-05-06)
Micro honeycomb materials enable new physics in aicraft sound reduction
Noise from commercial and military jet aircraft causes environmental problems for communities near airports, obliging airplanes to follow often complex noise-abatement procedures on takeoff and landing. It can also make aircraft interiors excessively loud. view more (2008-09-30)
Sensitivity of brain center for 'sound space' defined
While the visual regions of the brain have been intensively mapped, many important regions for auditory processing remain "uncharted territory." Now, researchers at the Hebrew University of Jerusalem and elsewhere have identified a region responsible for a key auditory process - perceiving "sound space," the location of sounds,... view more...

Face-to-face contact in a virtual environment
Although many sectors of the telecommunications industry are eagerly awaiting a ray of hope on the economic horizon, the prospects for video conferencing systems look good: Last year, sales on the European market increased by almost 15 percent, and the consultant Frost & Sullivan predicts that the growth rate will exceed 20 percent next year.... view more...
