Light may unlock a new quantum dance for electrons in graphene
20 hours ago
A team of researchers has devised a simple way to tune a hallmark quantum effect in graphene—the material formed from a single layer of carbon atoms—by bathing it in light. Their theoretical work, which was published ...

Serious environmental problems have arisen alongside the rapid economic development of China, including the well-known issue of haze pollution. Not only does haze bring low atmospheric visibility, causing traffic-related ...
New nanotweezers able to move sub-micrometer size objects in fluids
Jan 12, 2018 report
Two researchers with the Indian Institute of Science have developed tiny tweezers that can manipulate objects in fluids as small as an individual bacterium. In their paper published in the journal Science Robotics, Souvik ...
Quantum speed limit may put brakes on quantum computers
Jan 12, 2018
Over the past five decades, standard computer processors have gotten increasingly faster. In recent years, however, the limits to that technology have become clear: Chip components can only get so small, and be packed only ...
Magnetic coil springs accelerate particles on the Sun
Jan 11, 2018
In April and July 2014, the Sun emitted three jets of energetic particles into space, that were quite exceptional: the particle flows contained such high amounts of iron and helium-3, a rare variety of helium, as have been ...
Smoke from wildfires can tip air quality to unhealthy levels
Jan 09, 2018
Smoke plumes emanating from wildfires are swept high up into the air and spread over thousands of kilometers even days after a fire has been put out. The fine particles and harmful ozone contained in these plumes often have ...
Microbeads in cosmetics might already be on the way out, new research suggests
Jan 09, 2018
As the government ban on microbeads in cosmetics comes into force, scientists at the University of Plymouth have revealed companies appear to have taken action to eradicate the tiny particles from their products.
Surprising result shocks scientists studying spin
Jan 08, 2018
Imagine playing a game of billiards, putting a bit of counter-clockwise spin on the cue ball and watching it deflect to the right as it strikes its target ball. With luck, or skill, the target ball sinks into the corner pocket ...
