New record for measurement of atomic lifetime Eureka Alert Share    
Researchers at the Niels Bohr Institute have measured the lifetime of an extremely stable energy level of magnesium atoms with great precision. Magnesium atoms are used in research with ultraprecise atomic clocks. The new measurements show a lifetime of 2050 seconds. This is the longest lifetime ever measured in a laboratory. The results have been published in Physical Review Letters. More
On the future of particle accelerators Wired UK Share
Dave Britton is a professor of physics at the University of Glasgow and Project Leader of the GridPP project that provides grid computing for particle physics throughout the world. He sat down with Wired UK to talk about the difficulty of what he calls "looking for a bit of hay in a haystack," and what he sees as the future for large projects such as those at CERN. More
All-quantum-dot tandem solar cell could double power output, dramatically reduce costs Natcore Technology Share
A team working under Natcore Technology Inc. co-founder professor Andrew Barron has fabricated two families of multilayer quantum dot films, one with silicon quantum dots and the other with germanium quantum dots, both of which have demonstrated the ability to produce a photo-generated current. Each film is comprised of layers of silicon or germanium quantum dots embedded in a silica matrix, and are fabricated via liquid phase deposition as opposed to chemical vapor deposition. More
NASA needs more astronauts Fox News Share
The National Research Council's report, Preparing for the High Frontier — the Role and Training of NASA Astronauts in the Post-Space Shuttle Era, calls for the space agency to maintain a strong astronaut corps, even though human space flight has been temporarily stalled for NASA. Over the years, the number of astronauts employed by NASA has moved from about 150 in 1999 to 61 in 2011, and many astronauts have retired or quit this year. The NRC warns that 61 astronauts may not be enough. More
Physics explains sweet music to your ears American Physical Society Share
The most pleasing musical chords have simple mathematical relationships between the different sound frequencies within them, but the source of this perception is mysterious. A recent mathematical model suggests that the key may be the rhythmically consistent firing of neurons in response to a harmonious pair of frequencies. Now the researchers who developed the model report Physical Review Letters that they have quantified the effect by calculating the information content of their model's neural signals and showed that it increases for tone pairs that are more pleasant sounding.

Innovative superconductor fibers carry 40 times more electricity Physorg.com Share
A team in Israel has developed superconducting wires using fibers made of single crystals of sapphire to be used in high powered cables. Factoring in temperature requirements, each tiny wire can carry approximately 40 times more electricity than a copper wire of the same size. More
Do cosmic rays cause global warming? Moth Eyes Share
A recent Nature article has caused a firestorm of commentary. Many in the media jumped to the conclusion that cosmic rays were affecting the climate. One must wonder why people so "skeptical" about the well-established link between greenhouse gasses and global temperatures would be so quick to jump to conclusions when no such conclusions are supported, or even suggested, in the paper they each claim to be writing about.

Status of fiscal year 2012 funding bills American Institute of Physics Share
The next few months will be important in determining the funding of federal scientific research in fiscal year 2012. Although FY 2012 has not started, Congress is unlikely to settle on final budgets until later this year, resulting in continuing resolutions. The outlook is more promising for a quicker resolution of the final appropriations than in previous years because Congress and the administration have settled on an overall cap on FY 2012 discretionary spending. The House has completed most of the appropriations bills impacting physics, but the Senate has moved only on funding for the Department of Energy. More
Budget outlook for fiscal year 2013 Association of Schools of Public Health Share
In January, President Barack Obama will send his fiscal year 2013 budget request to Congress. The request will be bound by the provisions of the Budget Control Act that the president signed into law limiting discretionary spending to $1.047 trillion, a level that is 0.4 percent over than that for FY 2012. On Aug.17, Office of Management and Budget Director Jacob Lew distributed a two-page memorandum for the heads of departments and agencies calling for FY 2013 budget submissions to be 5 percent and 10 percent below the FY 2011 enacted discretionary appropriation.

Algeria gears up for National Festival in Astronomy Sirius Astronomy Association Share
 Algerian astronomers invite worldwide participation in the country's 10th National Festival on Popular Astronomy, Oct. 29-Nov. 2. The gathering is both an astronomy exposition and a series of seminars and workshops geared to the general public. The festival has grown to be the largest multinational
gathering of its kind in North Africa and even perhaps in Africa. This year's theme is "50 Years of Space Exploration." To encourage more participants, especially from Africa, full local accommodation and participation fees will be covered.
