A heartbreaking, out-of-the-gate failure of Russia’s sample return mission early this year created a wide circle of disappointment. For Russia, it was supposed to be a "cavalry charge" toward a hyperambitious goal that would have redeemed a quarter-century of interplanetary impotence but instead became a cosmic humiliation when the craft died shortly after liftoff. For planetary science, it meant that the composition of the Martian moon Phobos remains speculative and its origins still undetermined

(PhysOrg.com) -- Some physicists today are investigating the possibility of using molecular magnets as information storage units in future quantum computers.

(PhysOrg.com) -- When scientists discovered in 1998 that the Universe is expanding at an accelerating rate, the possibility that dark energy could explain the observation was intriguing. But because there has been little progress in figuring out exactly what dark energy is, the idea has since become more of a problem than a solution for some scientists. One physicist, Massimo Villata of the National Institute for Astrophysics (INAF) in Pino Torinese, Italy, describes dark energy as “embarrassing,” saying that the concept is an ad hoc element to standard cosmology and is devoid of any physical meaning.

Researchers working on the island of Borneo have discovered two tiny new populations of Miller’s grizzled langurs ( Presbytis hosei canicrus ), one of the world’s 25 most endangered primates. The species is so rare that it has probably disappeared from all of its previously known habitats, which have been almost completely logged and burned out of existence. The langur was last observed in 2008 ( pdf ) in an isolated patch of mangrove forest on the banks of the Baai River which flows through Borneo’s Sangkulirang Peninsula, when just five of the primates were found

(PhysOrg.com) -- In an effort to make computer chips even faster than those of today, many researchers have recently been investigating the possibility of optical computing. In an optical computer, information is encoded as photons rather than electrons, allowing large amounts of data to be processed simultaneously. But before an optical computer can be realized, researchers need to design a 3D structure that can sufficiently manipulate light.

The rise of computers in past decades was made possible largely thanks to the invention of the integrated circuit, a device that combines all necessary electronic components onto a single chip. In a similar vein, the success of optical computing is largely dependent on the possibility of integrating all essential optical components onto a single chip (photonic circuit). Lim Teck Guan at the A*STAR Institute of Microelectronics and co-workers have now developed an enhanced alignment solution for photonic circuits.

To probe the evolution of atomic nuclei with different shape -- a factor which affects atomic stability -- a large team of international researchers has added neutrons to zirconium atoms and revealed the possibility of very unusual shapes. "The shape of a nucleus reflects the symmetry of its quantum state," explains team member Hiroyoshi Sakurai from the RIKEN Nishina Center for Accelerator-Based Science in Wako, Japan.

(PhysOrg.com) -- A high-temperature superconductor can now be switched on and off within a trillionth of a second – 100 years after the discovery of superconductivity and 25 years after the first high-temperature superconductor was. A team including physicists from the University of Oxford and the Max Planck Research Group for Structural Dynamics at the University of Hamburg has realised an ultrafast superconducting switch by using intense terahertz pulses.
