When a star is tidally disrupted by a supermassive black hole (SMBH), the streams of liberated gas form an accretion disk after their return to pericenter. We demonstrate that Lense-Thirring precession in the spacetime around a rotating SMBH can produce significant time evolution of the disk angular...

From detailed angle-resolved NMR and Meissner measurements on a ferromagnetic (FM) superconductor UCoGe (TCurie∼2.5 K and TSC∼0.6 K), we show that superconductivity in UCoGe is tightly coupled with longitudinal FM spin fluctuations along the c axis. We found that magnetic fields along the c axis (...

In rhombohedral CaMn7O12, an improper ferroelectric polarization of magnitude 2870 μC m-2 is induced by an incommensurate helical magnetic structure that evolves below TN1=90 K. The electric polarization was found to be constrained to the high symmetry threefold rotation axis of the crystal struc...

BBC: A plan to levy charges on flights in EU airspace based on carbon emissions has been criticized by the US, Canada, and China—and China has barred its airlines from participating. The plan was implemented at the beginning of the year. The EU has estimated that airline passengers will be charged €2–12 more per flight as a result of the plan. China claims that the plan would cost Chinese airlines €95 million a year if they took part. Although the EU could forbid Chinese airlines from flying in EU airspace, doing so could damage its relationship with China. Ultimately, the issue may have to be resolved by the World Trade Organization or another international body.
Ottawa Citizen: After a quarter century of courtroom battles, Chander Grover, a physicist and former manager of the National Research Council of Canada, has agreed to abandon his last remaining lawsuit against the NRC. Born in India, Grover first complained of unfair discrimination at the NRC in 1987. In 1992 he won a landmark human rights case against the council, whose managers were shown to have "thwarted his advancement, humiliated him, unfairly fired him, then tried to intimidate witnesses from testifying on his behalf," writes Andrew Duffy for the Ottawa Citizen. Grover then proceeded to file four more human rights complaints against the NRC and was dismissed in July 2007 for "medical incapacity." Last year Grover underwent cancer treatments. "It's impossible at my age to continue and with all of the health problems I'm facing and my wife is facing," he said. "It's important, but what can I do?" He now plans to write a book about his experience.
Reuters: Early Sunday a fire broke out at the Alikhanov Institute of Theoretical and Experimental Physics, a nuclear research center in Moscow that houses a nonoperational 60-year-old atomic reactor. Although institute officials maintain that there was no risk of a radiation leak, Greenpeace Russia officials expressed concern. The fire, which broke out in a basement area of the facility, consisted primarily of smoke that came from an area housing power cables. The smoke was visible above the institute, and an acrid smell filled the air. About 30 emergency vehicles responded. Russian news agencies issued conflicting reports, including whether fire brigades were initially denied access and when exactly the fire was extinguished.

The recorded sound is wonderful, and Finnish conductor Susanna Mälkki coaxes a sound of golden warmth from her Swedish orchestra. Swedish mezzo-soprano Katarina Karnéus makes a sound as rich and glossy as a thoroughbred’s coat. --The Telegraph, 14th July 2011 ***
