Researchers design the most precise quantum thermometer to date
Jun 11, 2015 (SPX)
Researchers from the UAB and the University of Nottingham, in an article published in Physical Review Letters, have fixed the limits of thermometry, i.e., they ...
Vanishing friction
Jun 11, 2015 (SPX)
Friction is all around us, working against the motion of tires on pavement, the scrawl of a pen across paper, and even the flow of proteins through the bloodstr...
Crossing a critical threshold in optical communications
Jun 11, 2015 (SPX)
Researchers from Lehigh University, Japan and Canada have advanced a step closer to the dream of all-optical data transmission by building and demonstrating wha...
Donuts, math, and superdense teleportation of quantum information
Jun 09, 2015 (SPX)
Putting a hole in the center of the donut--a mid-nineteenth-century invention--allows the deep-fried pastry to cook evenly, inside and out. As it turns out, the...
Visualizing the 'matrix'
Jun 09, 2015 (SPX)
Magnetic resonance tomography (MRT) images are an important diagnostic tool. The achievable contrast depends on how well the nuclear spins that form the basis o...
Physicists precisely measure interaction between atoms and carbon surfaces
Jun 05, 2015 (SPX)
Physicists at the University of Washington have conducted the most precise and controlled measurements yet of the interaction between the atoms and molecules th...
How to cut a vortex into slices
Jun 05, 2015 (SPX)
A lot of problems, associated with the mixing of the liquid in the microchannels, could be solved via proper organization of the inhomogeneous slip on the walls...
A new tool measures the distance between phonon collisions
Jun 05, 2015 (SPX)
Today's computer chips pack billions of tiny transistors onto a plate of silicon within the width of a fingernail. Each transistor, just tens of nanometers wide...
Hubble sees shock collision inside black hole jet
May 31, 2015 (SPX)
When you're blasting though space at more than 98 percent of the speed of light, you may need driver's insurance. Astronomers have discovered for the first time...
Isolating sunlight scattering could help illuminate Universe's birth
May 31, 2015 (SPX)
Astrophysicists have developed a new method for calculating the effect of Rayleigh scattering on photons, potentially allowing researchers to better understand ...
Squeezed quantum cats
May 29, 2015 (SPX)
Quantum physics is full of fascinating phenomena. Take, for instance, the cat from the famous thought experiment by the physicist Erwin Schrodinger. The cat can...
How spacetime is built by quantum entanglement
May 29, 2015 (SPX)
A collaboration of physicists and a mathematician has made a significant step toward unifying general relativity and quantum mechanics by explaining how spaceti...
Large Hadron Collider Smashes its own Particle-Smashing Record
May 29, 2015 (Sputnik)
As the Large Hadron Collider, humanity's most colossal science experiment, approaches its relaunch date, test runs are already making waves. On Thursday, the un...
On-demand X-rays at synchrotron light sources
May 28, 2015 (SPX)
Consumers are now in the era of "on-demand" entertainment, in which they have access to the books, music and movies they want thanks to the internet. Likewise, ...
Researchers discover 'swing-dancing' pairs of electrons
May 25, 2015 (SPX)
A research team led by the University of Pittsburgh's Jeremy Levy has discovered electrons that can "swing dance." This unique electronic behavior can potential...
Researchers build new fermion microscope
May 25, 2015 (SPX)
Fermions are the building blocks of matter, interacting in a multitude of permutations to give rise to the elements of the periodic table. Without fermions, the...
Physicists observe real-time restructuring of electron cloud in attoseconds
May 25, 2015 (SPX)
The recombination of electron shells in molecules, taking just a few dozen attoseconds (a billionth of a billionth of a second), can now be viewed "live," thank...
Two Large Hadron experiments observe rare subatomic process
May 22, 2015 (SPX)
Two experiments at the Large Hadron Collider at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, have combined their results and ob...
Quantum physics on tap
May 21, 2015 (SPX)
We all know intuitively that normal liquids flow more quickly as the channel containing them tightens. Think of a river flowing through narrow rapids. But what ...
Left-handed cosmic magnetic field could explain missing antimatter
May 21, 2015 (SPX)
The discovery of a 'left-handed' magnetic field that pervades the universe could help explain a long standing mystery - the absence of cosmic antimatter. A grou...
