'Nano-earthquakes' hold key to smarter electronics
The performance of mobile phone cameras and solar cells could be boosted by "nano-earthquakes", researchers have found.
Electron spins controlled using sound waves
The ability to control the intrinsic angular momentum of individual electrons – their "spins" – could lead to a world of new technologies that involve storing and processing information.
A new way to control information by mixing light and sound
For once, slower is better in a new piece of technology.
Study examines role of acoustic-gravity waves as ocean transport, early warning of tsunamis
Acoustic-gravity waves—a special type of sound wave that can cut through the deep ocean at the speed of sound—can be generated by underwater earthquakes, explosions, and landslides, as well as by surface ...
Weighing gas with sound and microwaves
NIST scientists have developed a novel method to rapidly and accurately calibrate gas flow meters, such as those used to measure natural gas flowing in pipelines, by applying a fundamental physical principle: ...
Acoustic levitation made simple
A team of researchers at the University of São Paulo in Brazil has developed a new levitation device that can hover a tiny object with more control than any instrument that has come before.
Geo-researchers making diamonds out of odd materials, including peanut butter
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.
Ancient auditory illusions reflected in prehistoric art?
Some of mankind's earliest and most mysterious artistic achievements—including prehistoric cave paintings, canyon petroglyphs and megalithic structures such as Stonehenge—may have been inspired by the ...
Tomorrow's tablets? Look, no hands
Engineers in a suburban Chicago office complex have designed a new microphone that they say will be key to the future of smartphone and tablet technology because it gives consumers the ability to operate hand-held devices ...
Finding hints of gravitational waves in the stars
Scientists have shown how gravitational waves—invisible ripples in the fabric of space and time that propagate through the universe—might be "seen" by looking at the stars. The new model proposes that ...
The sound of an atom has been captured
Researchers at Chalmers University of Technology are first to show the use of sound to communicate with an artificial atom. They can thereby demonstrate phenomena from quantum physics with sound taking on ...
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 ...
New device based on fly's freakishly acute hearing may find applications in futuristic hearing aids
Even within a phylum so full of mean little creatures, the yellow-colored Ormia ochracea fly is distinguished among other arthropods for its cruelty—at least to crickets. Native to the southeastern U.S. ...
