Light-powered gyroscope is world's smallest: Promises powerful spin on navigation
A pair of light waves - one zipping clockwise the other counterclockwise around a microscopic track - may hold the key to creating the world's smallest gyroscope: one a fraction of the width of a human hair. ...
Engineering students use sound waves to put out fires
Quantum experiment verifies Einstein's 'spooky action at a distance'
An experiment devised in Griffith University's Centre for Quantum Dynamics has for the first time demonstrated Albert Einstein's original conception of "spooky action at a distance" using a single particle.
"Mini supernova" explosion could have big impact
In Hollywood blockbusters, explosions are often among the stars of the show. In space, explosions of actual stars are a focus for scientists who hope to better understand their births, lives, and deaths and ...
Seismic study aims to map Earth's interior in 3-D
When a 7.9-magnitude earthquake struck central China's Sichuan province in 2008, seismic waves rippled through the region, toppling apartment houses in the city of Chengdu and swaying office buildings 1,000 ...
'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.
Mysterious phenomena in a gigantic galaxy-cluster collision
Researchers using the Karl G. Jansky Very Large Array (VLA) have produced the most detailed image yet of a fascinating region where clusters of hundreds of galaxies are colliding, creating a rich variety ...
Image: The twisted shockwaves of an exploded star
Discovered on 5 September 1784 by astronomer William Herschel, the Veil Nebula was once a star. Now it is a twisted mass of shock waves that appears six times larger than the full Moon in the sky.
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.
Evidence indicates Yucatan Peninsula hit by tsunami 1,500 years ago
The eastern coastline of Mexico's Yucatan Peninsula, a mecca for tourists, may have been walloped by a tsunami between 1,500 and 900 years ago, says a new study involving Mexico's Centro Ecological Akumal ...
Breakthrough in nonlinear optics research
A method to selectively enhance or inhibit optical nonlinearities in a chip-scale device has been developed by scientists, led by the University of Sydney. The researchers from the Centre for Ultrahigh bandwidth ...
A new way to control information by mixing light and sound
For once, slower is better in a new piece of technology.
New insight found in black hole collisions
New research by an astrophysicist at The University of Texas at Dallas provides revelations about the most energetic event in the universe—the merging of two spinning, orbiting black holes into a much larger ...
Study outlines impact of tsunami on the Columbia River
Engineers at Oregon State University have completed one of the most precise evaluations yet done about the impact of a major tsunami event on the Columbia River, what forces are most important in controlling ...
