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.
The secrets of owls' near noiseless wings
Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence.
Network turns soldiers' helmets into sniper location system
(PhysOrg.com) -- Imagine a platoon of soldiers fighting in a hazardous urban environment who carry personal digital assistants that can display the location of enemy shooters in three dimensions and accurately ...
Physicists split and collide ultracold atom clouds (w/ Video)
Physicists at New Zealand's University of Otago have pushed the frontiers of quantum technology by developing a steerable 'optical tweezers' unit that uses intense laser beams to precisely split minute clouds ...
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 ...
Why does Venus' atmosphere rotate sixty times faster than its surface?
Venus is a slowly rotating planet since it takes about two hundred and forty three terrestrial days to complete a round about itself. Its atmosphere is expected to rotate with the same rhythm as well, but ...
New imaging technique could detect acoustically 'invisible' cracks
The next generation of aircraft could be thinner and lighter thanks to the development of a new imaging technique that could detect damage previously invisible to acoustic imaging systems.
Metafluids: German researchers realize new material class
A research team lead by Professor Martin Wegener at the Karlsruhe Institute of Technology has succeeded in realizing a new material class through the manufacturing of a stable crystalline metafluid, a pentamode ...
Radiation damage bigger problem in microelectronics than previously thought
The amount of structural damage that radiation causes in electronic materials at the atomic level may be at least ten times greater than previously thought.
Acoustic levitation could be used on Mars
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 ...
