Africa could host the world's most powerful telescope
The Guardian    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The Australian/New Zealand and African teams have made their final submissions for their competing bids to host the Square Kilometer Array. In the last few weeks Australia has been touting that has less radiofrequency interference, and that it has a history of radio astronomy productivity as well as stable democratic governance. South Africa asserts that its site is just as radio-quiet, has more available infrastructure at the telescope's site, including stable grid-power, lower cost of construction and the world-class results its project team has achieved in system design. South Africa also touts the political, social and economic transformations on the continent that are already being catalyzed by the SKA project. More

Bismuth ferrite domains may improve solar cells
Optics and Photonics News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The photovoltaic mechanism by which a ferroelectric material generates high voltages could help create better solar cells. Bismuth ferrite forms domains with opposite electrical polarizations. By studying thin films researchers were able to understand how photovoltage accumulates their periodic domain pattern that leads to higher voltages than bismuth ferrite's bandgap. More

Physicists create brightest gamma-ray on Earth
Science Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The brightest gamma ray beam ever created — more than a thousand billion times more brilliant than the sun — has been produced in research led at the University of Strathclyde. The beams are so intense they can pass through 20 centimeters of lead and would take 1.5 meters of concrete to be completely absorbed. The pulses are so ultrashort that the beam can be used to capture the response of a nucleus to stimuli, making the rays ideal for use in lab-based study of the nucleus. More

Tsunami puzzle explained
American Physical Society    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A tsunami normally consists of multiple waves, and in some cases, the first wave is not the tallest or the most damaging. A computer simulation reported in Physical Review Letters explains why the secondary waves can wash farther onshore than the initial wave. These later waves can be amplified by a resonance effect if each wave arrives at the beach just after the previous wave has receded. More

Graphene bubbles could make better lenses
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A tiny bubble of graphene could be used to make an optical lens with an adjustable focal length. That is the claim of Andre Geim and Konstantin Novoselov — who shared the 2010 Nobel Prize for Physics for discovery of graphene. In work published in Applied Physics Letters, they have shown that the curvature of such bubbles can be controlled by applying an external voltage. More



Algeria plans further growth for science
Science Development Network    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Algeria is pressing ahead with further increases to its science budget, according to a report presented by the Ministry for Scientific Research at a meeting chaired by the country's president, Abdelaziz Bouteflika. The budget has already increased to 1 percent of gross domestic product — three times what it was five years ago — and this is expected to increase to 1.2 percent next year, notes the report. More

South Africa and Mauritius agree to build low-frequency array telescope
AllAfrica.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
South Africa's Minister of Science and Technology, Naledi Pandor, met with her counterpart from Mauritius, Rajesh Jeetah, and agreed that the two countries would construct a radio telescope array in preparation for the Square Kilometer Array. Dubbed the Multifrequency Interferometry Telescope for Radio Astronomy, the project will aim to do extremely wide-field imaging with heterogeneous noncoplanar arrays. More

Quantum simulation hits the open road
American Physical Society    Share    Share on FacebookTwitterShare on LinkedinE-mail article
One of the most important practical applications of a quantum computer would be the simulation of other quantum systems. Until now, the possibility of an accurate simulation had been rigorously demonstrated only for closed quantum systems — those with no decoherence or dissipation due to interactions with an environment. In Physical Review Letters, physicists in Germany have shown that open quantum systems — those which interact with an environment — can also be efficiently simulated with quantum computers. More

Senate panel restores James Webb Space Telescope funding
Space.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A U.S. Senate panel has proposed giving NASA's James Webb Space Telescope about $150 million more for 2012 than the White House requested for the overbudget project, which appropriators in the House of Representatives voted this summer to cancel. The additional funding for JWST amounts to a 40 percent increase for the project and is part of a 2012 spending bill approved Sept. 14 by the Senate Appropriations commerce, justice, science subcommittee.
