For the first time, researchers at the California Institute of Technology (Caltech), in collaboration with a team from the University of Vienna, have managed to cool a miniature mechanical object to its lowest possible energy state using laser light. The achievement paves the way for the development of exquisitely sensitive detectors as well as for quantum experiments that scientists have long dreamed of conducting.

Boosting up microprocessors -the heart of modern computers- at the speed of light, reducing consumptions and costs, may now be a reality thanks to the development of a new high-performance chip, the results of which have been published in Nature Photonics.

(PhysOrg.com) -- An undergraduate student has overcome a major hurdle in the development of invisibility cloaks by adding an optical device into their design that not only remains invisible itself, but also has the ability to slow down light.

By Ewen Callaway of Nature magazine A controversial new study is questioning the oft-repeated connection between the consumption of too much salt and the development of cardiovascular disease.

(PhysOrg.com) -- Of the many exotic and counterintuitive aspects of particle and quantum physics, exciton and polariton quasiparticles are among the most interesting. An exciton forms when a photon is absorbed by a semiconductor as a Coulomb force-bound state of a (negatively-charged) electron and a (positively-charged) hole; this particle pair can be seen as an elementary excitation of condensed matter able to transport energy without the transfer of net electric charge, and moreover has size- and shape-dependent optoelectronic properties

The free electron laser is the next step in the development of equipment to help us see the structure of materials. Nino Čutić at MAX-lab in Lund, Sweden, has done a PhD in further improving the test free electron laser at the laboratory.

During the last several years of financial turbulence, the private aviation industry has reevaluated its business approach in order to maintain its appeal to the consumer.

Optical data carriers such as DVDs, Blu-rays and CD-RWs store data in layers of so-called "phase change materials". In the future, these materials will enable the development of fast, non-volatile and energy-saving main memories. A prerequisite for this is a low thermal conductivity

(PhysOrg.com) -- Like atomic-level bricklayers, researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are using a precise atom-by-atom layering technique to fabricate an ultrathin transistor-like field effect device to study the conditions that turn insulating materials into high-temperature superconductors.

If two men began a boisterous tug-of-war over the wine list at a posh restaurant, more than a few heads would turn. Yet two six-year-old kids quarreling over a pack of crayons at a diner would hardly seem unusual. It is normal for kindergartners to act out and for grown-ups to show restraint

(PhysOrg.com) -- Researchers from Swinburne University and the University of Shanghai for Science and Technology have for the first time ever demonstrated a reversal of the optical ‘Doppler Effect’ – an advance that could one day lead to the development of 'invisibility cloak' technology.

(PhysOrg.com) -- One of the subjects of immense interest to scientists (and non-scientists as well) is the development of quantum computers. However, there are many challenges associated with quantum computing. One of the difficulties to achieving practical quantum computing is related to the way the quantum bits (qubits) that make up a quantum computer are connected together.
