NASA spacecraft records 'Earthsong'
Nobody ever said anything about singing, though. A NASA spacecraft has just beamed back a beautiful song sung by our own planet.
Scientists twist sound with metamaterials
A Chinese-U.S. research team is exploring the use of metamaterials—artificial materials engineered to have exotic properties not found in nature—to create devices that manipulate sound in versatile and ...
Researchers use artificially engineered materials to create breakthrough for sound sensors
University of Maryland (UMD) A. James Clark School of Engineering researchers have developed breakthrough technology to improve sound sensor capabilities through the use of artificially engineered materials.
Sound could save circuits: Researchers theorize acoustic waves may cool microelectronics
(PhysOrg.com) -- "Hot sounds" has one meaning to music fans and another to physicists. Count a team of researchers at Rice University among the latter, as they've discovered that acoustic waves traveling along ...
Designing an acoustic diode
Most people know about ultrasound through its role in prenatal imaging: those grainy, grey outlines of junior constructed from reflected sound waves. A new technology called an "acoustic diode," envisioned ...
Tilted acoustic tweezers separate cells gently
Precise, gentle and efficient cell separation from a device the size of a cell phone may be possible thanks to tilt-angle standing surface acoustic waves, according to a team of engineers.
Scientists sweep cells apart for use in medical research
Scientists have developed a new method to separate cells, which could lead to more efficient medical research.
Sound bullets could treat cancers and replace ultrasound (w/ Video)
Bottling up sound waves
There's a new wave of sound on the horizon carrying with it a broad scope of tantalizing potential applications, including advanced ultrasonic imaging and therapy, acoustic cloaking, and levitation and particle ...
A unique glance into the Sun's atmosphere
Three months after the flight of the balloon-borne solar observatory Sunrise, scientists from the Max Planck Institute for Solar System Research (MPS) in Germany now present unique insights into the central ...
How do liquid foams block sound?
Liquid foams have a remarkable property: they completely block the transmission of sound over a wide range of frequencies. CNRS physicists working in collaboration with teams from Paris Diderot and Rennes ...
Moon's shadow, like a ship, creates waves
During a solar eclipse, the Moon's passage overhead blocks out the majority of the Sun's light and casts a wide swath of the Earth into darkness. The land under the Moon's shadow receives less incoming energy ...
Rap music powers rhythmic action of medical sensor
(PhysOrg.com) -- The driving bass rhythm of rap music can be harnessed to power a new type of miniature medical sensor designed to be implanted in the body.
