Researchers build fully mechanical phonon laser

( —Researchers working at Japan's NTT Basic Research Laboratories have successfully built an all mechanical phonon laser. In their paper published in Physical Review Letters, the team describes how they built a phonon laser without using any optical parts by basing it on a traditional optical laser design.

Laser-like photons signal major step towards quantum 'Internet'

The realization of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from "solid-state" chips, bringing us closer to the quantum "Internet."

Powerful New Radio Telescope Officially Kicks Off Observations

By Govert Schilling

Just over a week ago, at three miles above sea level in the Chilean Atacama desert, Atacameño indians offered gifts to Mother Earth in a traditional ceremony to bless a decidedly modern object: the Atacama Large Millimeter/submillimeter Array (ALMA). Four days later, on March 13, the largest-ever ground-based astronomical observatory was officially inaugurated. “ALMA is now a reality, and not a fairy tale anymore,” said Dutch astronomer Thijs de Graauw, the project’s direc

Electrons are not enough: Cuprate superconductors defy convention

To engineers, it's a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists have now found that for copper-containing superconductors, known as cuprates, electrons are not enough to carry the current.

NASA to Hold News Teleconference to Discuss Planck Cosmology Findings (Update)

NASA will host a news teleconference at 11 a.m. EDT, Thursday, March 21, to discuss the first cosmology results from Planck, a European Space Agency mission with significant NASA participation.

Herschel Discovers Some of the Youngest Stars Ever Seen

Astronomers have found some of the youngest stars ever seen thanks to the Herschel space observatory, a European Space Agency mission with important NASA contributions.

Causing collapse: Can one affect an atom's spin just by adjusting the way it is measured?

One of the most basic laws of quantum mechanics is that a system can be in more than one state -- it can exist in multiple realities -- at once. This phenomenon, known as the superposition principle, exists only so long as the system is not observed or measured in any way. As soon as such a system is measured, its superposition collapses into a single state. Thus, we, who are constantly observing and measuring, experience the world around us as existing in a single reality. Researchers now suggest one can affect an atom's spin just by adjusting the way it is measured.

'Lasing' operation in an ultrasonic vibration using a MEMS oscillator

Nippon Telegraph and Telephone Corporation has succeeded in fabricating a novel ultrasonic oscillator by applying a principle analogous to an optical laser, which is widely used as a highly purified light source, to a microelectromechanical systems (MEMS). The frequency purity of the output vibration is less than 1 part in1,000,000.

Student finds incubators have wildly varying magnetic fields

Lucas Portelli, a doctoral student in the University of Colorado Boulder's Department of Electrical, Computer and Energy Engineering, wanted to know how electromagnetic fields affect living things.

The Higgs boson looks just like Marc Sher said it would. Now what?

It turns out that the Higgs boson looks exactly like Marc Sher always said it would, and now he's a little bummed.
