Archive Trawl Gives Bison Three Decades Of Solar Music
Scientists in Birmingham have scoured the archives and put together a complete archive of helioseismic data for nearly three solar cycles. The results from reprocessing the data will shed light on the link between helioseismology, the study of sound waves resonating within the Sun, and solar activity. Dr Graham Verner will be presenting... view more... (2005-03-30)
'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)
Scientists unveil mysteries of plasma jets on the Sun
Scientists at the University of Sheffield and Lockheed Martin Solar and Astrophysics Lab have solved a 127-year-old problem about the origin of supersonic plasma jets (spicules) which continuously shoot up from the Sun. Their findings are published in today's edition of Nature. Spicules, are jets of gas or plasma that are propelled upwards from... view more... (2004-07-29)
Deep subsurface research to help understand earthquakes
From 8 to 20 October, TU Delft, "Vrije Universiteit Amsterdam" and The University of Utrecht will be conducting an experiment in the south of the Netherlands. The experiment is to find out how the deep subsurface (about 25 to 30 km under the surface) can be profiled with sound waves. It is the first time that Dutch subsurface will be... view more...

New findings contradict a prevailing belief about the inner ear
A healthy ear emits soft sounds in response to the sounds that travel in. Detectable with sensitive microphones, these otoacoustic emissions help doctors test newborns' hearing. A deaf ear doesn't produce these echoes. view more (2008-02-13)
Mathematicians find way to improve medical scans
Mathematicians at the University of Liverpool have found that it is possible to gain full control of sound waves which could lead to improved medical scans, for technology such as ultra sound machines. view more (2008-01-08)
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)
Ultrasound researchers make no bones about their work

Shifting sound to light may lead to better computer chips
By reversing a process that converts electrical signals into sounds heard out of a cell phone, researchers may have a new tool to enhance the way computer chips, LEDs and transistors are built. view more (2009-03-17)
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)
A sonic boom in the world of lasers
It was an idea born out of curiosity in the physics lab, but now a new type of 'laser' for generating ultra-high frequency sound waves instead of light has taken a major step towards becoming a unique and highly useful 21st century technology. view more (2009-06-18)
Magnetic field uses sound waves to ignite sun's ring of fire
Sound waves escaping the sun's interior create fountains of hot gas that shape and power a thin region of the sun's atmosphere which appears as a ruby red "ring of fire" around the moon during a total solar eclipse, according to research funded by the National Science Foundation (NSF) and NASA. view more (2007-05-30)
Caltech scientists first to trap light and sound vibrations together in nanocrystal
Researchers at the California Institute of Technology (Caltech) have created a nanoscale crystal device that, for the first time, allows scientists to confine both light and sound vibrations in the same tiny space. view more (2009-10-26)
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)
UK researchers aim to create black holes in the lab
Physicists in the UK are planning pioneering experiments to create tiny, artificial black holes in the laboratory which will be able to suck in light or sound waves. The researchers hope that the desk-top black holes will provide important information about the fundamental behaviour of matter and energy and help to resolve some of the apparent... view more...

St. Jude study solves mystery of mammalian ears
A 30-year scientific debate over how specialized cells in the inner ear amplify sound in mammals appears to have been settled more in favor of bouncing cell bodies rather than vibrating, hair-like cilia. view more (2007-07-30)
Starquakes reveal stellar secrets
Looking into the interior of the Earth or the Sun is a bit similar to examining a baby in its mother`s womb using an ultrasound scan. Light cannot penetrate the area, so we make pictures in these cases using sound waves, which human ears cannot hear. With SOHO, ESA has probed deeply into the Sun using the sound-waves principle, and with great... view more... (2002-08-14)
Making monster waves
Rogue waves-giant waves that spring up suddenly and tower over the seas around them-have inspired physicists to look for an analogue in light. view more (2009-10-20)
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)
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)
