Quantum-to-classical transition may be explained by fuzziness of measurement references
Maxwell's demon can use quantum information to generate work
Young scientist discovers magnetic material unnecessary to create spin current
It doesn't happen often that a young scientist makes a significant and unexpected discovery, but postdoctoral researcher Stephen Wu of the U.S. Department of Energy's Argonne National Laboratory just did exactly that. What ...
Bringing back the magic in metamaterials
A single drop of blood is teeming with microorganisms—imagine if we could see them, and even nanometer-sized viruses, with the naked eye. That's a real possibility with what scientists call a "perfect lens." The lens hasn't ...
CERN's LHCb experiment reports observation of exotic pentaquark particles
Today, the LHCb experiment at CERN's Large Hadron Collider has reported the discovery of a class of particles known as pentaquarks. The collaboration has submitted a paper reporting these findings to the journal Physical ...
Nanoscale device that can emit light as powerfully as an object 10,000 times its size
University of Wisconsin-Madison engineers have created a nanoscale device that can emit light as powerfully as an object 10,000 times its size. It's an advance that could have huge implications for a variety of imaging and ...
Why do puddles stop spreading? Simple everyday phenomenon was unexplained by physics—until now
When you spill a bit of water onto a tabletop, the puddle spreads—and then stops, leaving a well-defined area of water with a sharp boundary.
Researchers build molecules using a laser beam
First stars in the universe left a unique signature
Determining the chemical abundance pattern left by the earliest stars in the universe is no easy feat. A Lawrence Livermore National Laboratory (LLNL) scientist is helping to do just that.
