Update on superluminal neutrinos
Physicsworld.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
New data from OPERA's sister experiment ICARUS have failed to yield any evidence for superluminal neutrinos. More precisely, ICARUS has shown that neutrinos traveling from CERN to Gran Sasso do not emit electron–positron pairs. Emission of such pairs is expected if the neutrinos travel faster than the speed of light, according to a preprint published recently by Andrew Cohen and Sheldon Glashow. More

South Africa to create national astronomy agency
Business Day    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In a widely anticipated move, South Africa's S&T minister, Naledi Pandor, has announced the intention to create a national independent agency to manage the country's entire portfolio of astronomy programs. South Africa is the home of the Southern Africa Large Telescope, the largest single optical telescope in the southern hemisphere, and hosts a number of other optical telescopes at the site in Sutherland. In making a strong bid to host the Square Kilometer Array, South Africa has completed the construction of the SKA precursor, KAT-7, and has committed to building the larger SKA precursor, MeerKAT, which itself will be one of the world's most powerful telescopes. The 50-year-old Hartebeesthoek Radio Astronomy Observatory continues to produce important results, including being a key part of the African VLBI Network. Additional programs are being contemplated in IR astronomy to complete a multiwavelength capability on the continent, as well as in gravitational wave astronomy. And in addition to the investment in facilities, South Africa has invested in people through the establishment of the National Astrophysics and Space Sciences Program, the SKA Bursary Program and the South Africa Research Chairs Initiative. South Africa also hosts the International Astronomical Union's Office of Astronomy for Development .

Reiterating a point made in her speech at the National Society of Black Physicists' conference in September, Pandor also said that South Africa will support the Namibian bid to host the Cherenkov Telescope Array instead of entering its own bid. The Namibian site, which already hosts the HESS observatory, already enjoys close contacts with the gamma-ray astrophysics community in South Africa, and meets the technical specifications for the CTA just as well as, if not better than, the sites that could have been offered in South Africa.

Faster-than-light neutrino puzzle claimed solved by special relativity
Technology Review    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Ronald van Elburg at the University of Groningen in the Netherlands has suggested that one effect that the OPERA team seems to have overlooked: the relativistic motion of the GPS clocks. Although the speed of light does not depend on the the frame of reference, the time of flight does. In this case, there are two frames of reference: the experiment on the ground and the clocks in orbit. If these are moving relative to each other, then this needs to be factored in. More



American Physical Society responds to Texas closures
APS    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The president of the American Physical Society has sent a letter to the Texas Higher Education Coordinating Board that urges the THECB to carefully consider the repercussions that will ensue from terminating the ability to offer BA or BS degrees at a number of low-enrollment physics programs in Texas. Chief amongst the repercussions are the loss of departments that can effectively educate high school physics teachers, and the impact on Hispanic and African-American students as the affected universities disproportionally serve these communities, with doubled or tripled rates of graduation by underrepresented groups from the programs slated for closure compared to Texas public institutions as a whole.

This state-of-the-art classroom makes physics fun
Orlando Sentinel    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The new "studio" classroom at Bishop Moore Catholic High in Orlando, Fla., is not only a showcase for state-of-the-art technology, but also for the belief that students learn best if teachers ask questions, present problems, prod them to think and then get out of the way and let them work. Bishop Moore's new classroom is modeled on a concept begun more than a decade ago in the physics department at North Carolina State University. It has since spread to more than 100 colleges and universities, from Clemson to Florida State to the Massachusetts Institute of Technology. More

Image of forming planet captured
The Associated Press via The Boston Globe    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Adam Kraus, of the University of Hawaii's Institute for Astronomy, has captured the first direct image of a planet being born. The planet is being formed out of dust and gas circling a 2-million-year-old star about 450 light years from Earth. Based on scientific models of how planets form, it is estimated to have started taking shape about 50,000 to 100,000 years ago. More

Dark matter mystery deepens
Harvard-Smithsonian Center for Astrophysics    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A recent study has found that in two nearby galaxies the dark matter is distributed uniformly over a relatively large region, several hundred light-years across. This contradicts the prediction that the density of dark matter should increase sharply toward the centers of these galaxies. The new measurements imply that either normal matter affects dark matter more than expected, or dark matter isn't "cold," i.e., slow-moving. More



Comet storm in nearby solar system could mean Earth-like worlds
Jet Propulsion Laboratory    Share    Share on
FacebookTwitterShare on LinkedinE-mail article
Icy comets could be bombarding an alien solar system in a storm resembling the one that is thought to have brought water and other life-forming ingredients to Earth several billion years ago. NASA's Spitzer Space Telescope has spotted a band of dust around a nearby bright star in the northern sky called Eta Corvi that strongly matches the contents of an obliterated giant comet. This dust is located close enough to Eta Corvi that Earth-like worlds could exist, suggesting a collision took place between a planet and one or more comets. More

Using new technique, scientists uncover a delicate magnetic balance for superconductivity
ScienceDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A modified scanning tunneling microscope where researchers can pull or push electrons into a material has allowed a team at Cornell University's Laboratory for Atomic and Solid State Physics to visualize what happens when they change the electronic structure of a "heavy fermion" compound made of uranium, ruthenium and silicon. Using this technique they have found that while at higher-temperatures magnetism is detrimental to superconductivity, at low temperatures in heavy fermion materials, magnetic atoms are a necessity.

Very Large Array wants your help with a new name
TG Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The National Radio Astronomy Observatory is asking for help with coming up with a new name for the Very Large Array. The original VLA has been in use since the 1970s. But over the last 10 years, the NRAO has been working to replace 1970s electronics, upgrading the radio telescope's technical capabilities by 80 times, and says it wants a new name to reflect its new features. The competition runs until Dec. 1, and there's an online entry form here. More

Spiral arms point to possible planets in a star's dusty disk
NASA Goddard Space Flight Center    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A new image of the disk of gas and dust around a sun-like star is the first to show spiral-arm-like structures. These features may provide clues to the presence of embedded but as-yet-unseen planets. A near-infrared image from the National Astronomical Observatory of Japan shows a pair of spiral features arcing along the outer disk. Theoretical models show that a single embedded planet may produce a spiral arm on each side of a disk. The structures around SAO 206462 do not form a matched pair, suggesting the presence of two unseen worlds, one for each arm. More

Can gamma-ray bursts destroy life on Earth?
LiveScience via msbnc.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The persistence of life on Earth may depend on massive explosions on the other side of the galaxy, according to a new theory that suggests gamma-ray bursts could have played a part in some of our planet's major extinction events. Gamma-ray bursts — thought to occur when two stars collide — can release tons of high-energy gamma-ray radiation into space. Researchers have found that such blasts could be contributing to the depletion of the Earth's ozone layer. Disruption of the ozone layer lets ultraviolet light filter down to the surface of the Earth, where it can change organisms by mutating their genes. Now, researchers are beginning to connect the timing of these gamma-ray bursts to extinctions on Earth that can be dated through the fossil record. More



Why there's no such thing as north and south
Scientific American    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The human mind often confuses familiarity with understanding. That is why many of us who studied science or engineering or mathematics in college find it hard to convince ourselves that electromagnetism — one of the four fundamental forces of nature — does not have a preferred handedness. (which in particular implies that one cannot use the laws of electromagnetism to explain our concept of left and right to far away aliens, or explain it to martians over the phone, as Richard Feynman put it).
