How the kettle got its whistle
(Phys.org) —Researchers have finally worked out where the noise that makes kettles whistle actually comes from – a problem which has puzzled scientists for more than 100 years.
New technique for visualizing blood flow involves carbon nanotubes and lasers
(Phys.org)—Stanford scientists have developed a fluorescence imaging technique that allows them to view the pulsing blood vessels of living animals with unprecedented clarity. Compared with conventional ...
Curiosity rover's laser instrument zaps first martian rock
(Phys.org) -- Today, NASA's Mars rover Curiosity fired its laser for the first time on Mars, using the beam from a science instrument to interrogate a fist-size rock called "Coronation."
Bring in the (nano) noise
(PhysOrg.com) -- At the forefront of nanotechnology, researchers design miniature machines to do big jobs, from treating diseases to harnessing sunlight for energy. But as they push the limits of this technology, ...
Stanford computer scientists find Internet security flaw

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.
Study reveals potential breakthrough in hearing technology
Computer engineers and hearing scientists at The Ohio State University have made a potential breakthrough in solving a 50-year-old problem in hearing technology: how to help the hearing-impaired understand ...
Scientists discover noise pollution effects on shellfish
(Phys.org) —Man-made noise in the oceans may have significant damaging effects on shellfish populations, according to a new international study published today.
Earthquakes and tectonics in Pamir Tien Shan
Real time analysis of shear waves as a means of earth quake hazard mitigation. First time observed continental subduction in a continent-continent collision.
Sonata in LHCb: The sound of antimatter (w/ Video)
In a recent paper the LHCb collaboration at CERN observed two particles changing from matter into antimatter and back again. Now the collaboration has turned that data into sound, so that you can listen to the music of antimatter.
The pink noise of water quality
Lakes and streams are an essential supply of freshwater. Monitoring their water quality relies on measuring their chemistry. Researchers from ETH Zürich and the British research institute CEH have discovered ...
Boat noise stops fish finding home
(Phys.org) —Boat noise disrupts orientation behaviour in larval coral reef fish, according to new research from the Universities of Bristol, Exeter and Liège. Reef fish are normally attracted by reef sound ...
Improving measurements by reducing quantum noise
If you want to measure something very precisely, such as slight variations of a length, then you are very likely to use light waves. However, many effects, such as variations of gravity, or surface forces, ...
