Seismologists have long relied on earthquakes or expensive tools like explosives to help create images of Earths interior, but a new method created by University of Colorado at Boulder researchers will produce quicker, cheaper and clearer images.
Rather than waiting for earthquakes, the researchers have now recovered surface wave information from ambient seismic noise that is constantly produced by fluctuations in the Earths atmosphere and oceans. Measuring surface waves is important because they help scientists get a clearer picture of the Earths interior, according to Michael Ritzwoller, director of CU-Boulders Center for Imaging the Earths Interior and a physics professor.
"This new technique will give us a better fundamental understanding of the planet by providing much better resolution of Earths interior," Ritzwoller said. "It also will diminish what is known in seismology as the tyranny of earthquakes, which means having to wait for an earthquake to happen to do our jobs."

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
