'Spooky action' builds a wormhole between 'entangled' particles
Dec 05, 2013 (SPX)
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as "spooky action at a distance," could be even spookie...
Fast, Furious, Refined: Smaller Black Holes Can Eat Plenty
Dec 04, 2013 (SPX)
Observations of a black hole powering an energetic X-ray source in a galaxy some 22 million light-years away could change our thinking about how some black hole...
No qualms about quantum theory
Dec 03, 2013 (SPX)
A colloquium paper published in EPJ D looks into the alleged issues associated with quantum theory. Berthold-Georg Englert from the National University of Singa...
Flashes of brilliance
Dec 03, 2013 (SPX)
Spontaneous bursts of light from a solid block illuminate the unusual way interacting quantum particles behave when they are driven far from equilibrium. The di...
Black hole jets pack a powerful punch
Nov 29, 2013 (SPX)
Black-hole jets recycle matter and energy into space and can affect when and where a galaxy forms stars. "Jets from supermassive black holes help determine a ga...
Do Black Holes Come in Size Medium?
Nov 27, 2013 (JPL)
Black holes can be petite, with masses only about 10 times that of our sun -- or monstrous, boasting the equivalent in mass up to 10 billion suns. Do black hole...
Scientists Seek Other Scientists for Cosmology Problem
Nov 27, 2013 (JPL)
How do you measure something that is invisible? It's a challenging task, but astronomers have made progress on one front: the study of dark matter and dark ener...
IceCube provides proof of neutrinos from the cosmos
Nov 26, 2013 (SPX)
The IceCube Neutrino Observatory at the South Pole was the first to discover ultrahigh-energy neutrinos which most likely were the result of cosmic acceleration...
Evidence of jet of high-energy particles from Milky Way's black hole
Nov 26, 2013 (SPX)
For decades, astronomers have sought strong evidence that the supermassive black hole at the center of our Milky Way galaxy is producing a jet of high-energy pa...
Searching for Cosmic Accelerators Via IceCube
Nov 25, 2013 (SPX)
In our universe there are particle accelerators 40 million times more powerful than the Large Hadron Collider (LHC) at CERN. Scientists don't know what these co...
Revisiting quantum effects in MEMS
Nov 25, 2013 (SPX)
Micro- and nano-electromechanical devices, referred to as MEMS and NEMS, are ubiquitous. These nanoscale machines with movable parts are used, for example, to t...
Chandra Helps Confirm Evidence of Jet in Milky Way's Black Hole
Nov 25, 2013 (SPX)
Astronomers have long sought strong evidence that Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, is producing a jet of hig...
Whither the teakettle whistle
Nov 25, 2013 (SPX)
Despite decades of brewing tea in a whistling kettle, the source and mechanism of this siren sound of comfort has never been fully described scientifically. Ack...
HZDR researchers simulate electrons in astrophysical plasma jets
Nov 25, 2013 (SPX)
Physicists of Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have been able to simulate the motion of billions of electrons within astrophysical plasma jets and ca...
IceCube pushes neutrinos to the forefront of astronomy
Nov 25, 2013 (SPX)
The IceCube Neutrino Observatory, a particle detector buried in the Antarctic ice, is a demonstration of the power of the human passion for discovery, where sci...
Black hole birth captured by cosmic voyeurs
Nov 22, 2013 (SPX)
Intelligent telescopes designed by Los Alamos National Laboratory got a front row seat recently for an unusual birth. "Los Alamos' RAPTOR telescopes in New Mexi...
Quantum state world record smashed
Nov 19, 2013 (SPX)
A normally fragile quantum state has been shown to survive at room temperature for a world record 39 minutes, overcoming a key barrier towards building ultrafas...
Astronomers reveal contents of mysterious black hole jets
Nov 15, 2013 (SPX)
