X-ray laser probes tiny quantum tornadoes in superfluid droplets
An experiment at the Department of Energy's SLAC National Accelerator Laboratory revealed a well-organized 3-D grid of quantum "tornadoes" inside microscopic droplets of supercooled liquid helium – the ...
Molecular engineers record an electron's quantum behavior
A team of researchers led by the University of Chicago has developed a technique to record the quantum mechanical behavior of an individual electron contained within a nanoscale defect in diamond. Their technique ...
Tunable quantum behavior observed in bilayer graphene
Columbia researchers have observed the fractional quantum Hall effect in bilayer graphene and shown that this exotic state of matter can be tuned by an electric field.
A counterintuitive phenomenon discovered: The coexistence of superconductivity with dissipation
For his doctoral dissertation in the Goldman Superconductivity Research Group at the University of Minnesota, Yu Chen, now a postdoctoral researcher at UC Santa Barbara, developed a novel way to fabricate ...
The goose bump sensor: A step toward direct detection of human emotional states
Can emotional states be measured quantitatively, and if so what would advertising, manufacturing and social media companies do with that data? Imagine a world in which a consumer's real-time physical and ...
Physicists propose way to use quantum bidding in bridge
New evidence for oceans of water deep in the Earth
Researchers from Northwestern University and the University of New Mexico report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form—the ...
'Safer' pesticide could create toxic mercury, study says
A compound in pesticides that replaced another banned for its harmful effects, may threaten humans and wildlife by reacting with mercury in natural water to form a toxic chemical, researchers said Tuesday.
Google and Asian firms laying US-Japan underwater cable
Google is partnering with five Asian telecom firms to build a $300 million underwater cable across the Pacific Ocean in a bid to meet surging Internet use.
Sniffing out billions in US currency smuggled across the border to Mexico
Criminals are smuggling an estimated $30 billion in U.S. currency into Mexico each year from the United States, but help could be on the way for border guards, researchers will report here today. The answer to the problem: ...
Keystone carbon pollution more than figured, study finds (Update)
The much-debated Keystone XL pipeline could produce four times more global warming pollution than the State Department calculated earlier this year, a new study concludes.
Electrons moving in a magnetic field exhibit strange quantum behavior
The dynamic behavior of electrons in magnetic fields is crucial for understanding physical processes, such as the quantum Hall effect, which are important in many areas of solid state physics, including electrical ...
Geography matters: Model predicts how local 'shocks' influence US economy
A sudden closing of a major airline hub such as the main Atlanta airport would undoubtedly leave thousands of travelers stranded. Because of Atlanta's hub status, such a blow would be felt nationally, altering ...
Samsung, Apple call truce in patent war outside US
Arch-rivals Samsung and Apple decided Wednesday to drop all patent disputes outside the United States, marking a partial ceasefire in a long-running legal war between the world's two largest smartphone makers.
