16 atomic ions simulate a quantum antiferromagnet
(Phys.org) —Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter ...
Seeing Previously Invisible Molecules for the First Time
(PhysOrg.com) -- A team of Harvard chemists led by X. Sunney Xie has developed a new microscopic technique for seeing, in color, molecules with undetectable fluorescence. The room-temperature technique allows ...
Fracking shifts global energy balance
North America's shale oil and gas boom has shifted the balance in global energy markets, giving the US and Canada new leverage as exporters, despite the Middle East retaining a pivotal role.
US protesters urge Obama to act on global warming
Thousands of protesters gathered in Washington Sunday for a rally to press President Barack Obama to take concrete measures to help fight global warming.
Dance like a neutrino: Quantum scheme to simulate neutrino oscillations
The behaviour of some of the most elusive particles in the known universe can be simulated using three atoms in a lab, researchers at the Centre for Quantum Technologies (CQT) at the National University of Singapore have ...
Hibernating lemurs hint at the secrets of sleep
By studying hibernation, a Duke University team is providing a window into why humans sleep. Observations of a little-known primate called the fat-tailed dwarf lemur in captivity and the wild has revealed ...
Non-equilibrium quantum states in atmospheric chemistry
(Phys.org)—Research that sheds new light on the microscopic chemical physics driving one of the most important reaction sequences in atmospheric chemistry is published in Science today by Dr David Glowac ...
US grabs lead over China in clean energy race
The United States has regained the lead in the clean energy race, investing $48 billion last year to surpass China, which held the world's top spending spot since 2009, said a study Wednesday.
China a surprise leader in clean energy: study
The world's top polluter, China, is a surprise leader in clean energy efforts, a study showed Tuesday, outstripping the United States and Japan and leaving Australia lagging far behind.
Tevatron retires: The era of big American physics about to end
The era of big American physics ends Friday with the retirement of the Tevatron particle accelerator, which has been recreating the Big Bang under four miles of Illinois prairie for 25 years.
EU, US should abandon biofuels: UN rapporteur
The European Union and the United States should stop using biofuels as they are hampering food production, the UN's special rapporteur for the right to food Olivier De Schutter told AFP on Wednesday.
Theoretical research reveals that experimental crystal structure of an important energy material is impossible
