Maze-solving automatons can repair broken circuits (w/ video)
Physicists propose method to measure variations in the speed of light
Photon 'afterglow' could transmit information without transmitting energy
Universe may be on the brink of collapse (on the cosmological timescale)
Loophole in theory offers insight into the 'lithium problem'
Could classical theory be just as weird as quantum theory?
Scientists go to great lengths to extend superlow friction
New electronic paper could make inexpensive electronic displays
Researchers from the University of Tokyo have revamped an old e-paper concept to make an inexpensive handwriting-enabled e-paper well suited to large displays like whiteboards. They describe the e-paper in ...
Flip-flopping black holes spin to the end of the dance
When black holes tango, one massive partner spins head over heels (or in this case heels over head) until the merger is complete, said researchers at Rochester Institute of Technology in a paper published ...
Researchers use 'soft' nanoparticles to model behavior at interfaces
Where water and oil meet, a two-dimensional world exists. This interface presents a potentially useful set of properties for chemists and engineers, but getting anything more complex than a soap molecule ...
Black holes don't erase information, scientists say
The "information loss paradox" in black holes—a problem that has plagued physics for nearly 40 years—may not exist.
Quantum sensor's advantages survive entanglement breakdown
The extraordinary promise of quantum information processing—solving problems that classical computers can't, perfectly secure communication—depends on a phenomenon called "entanglement," in which the ...
Squeezing out new science from material interfaces
With more than five times the thermal conductivity of copper, diamond is the ultimate heat spreader. But the slow rate of heat flow into diamond from other materials limits its use in practice. In particular, ...
When temperature goes quantum
A UA-led collaboration of physicists and chemists has discovered that temperature behaves in strange and unexpected ways in graphene, a material that has scientists sizzling with excitement about its potential ...
