New way to produce antimatter-containing atom discovered
Physorg.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Physicists at the University of California, Riverside, report that they have discovered a new way to create positronium, an exotic and short-lived atom that could help answer what happened to antimatter in the universe, why nature favored matter over antimatter at the universe's creation. More

Tevatron particles shed light on antimatter mystery
New Scientist    Share    Share on FacebookTwitterShare on LinkedinE-mail article
New results from the Tevatron may help explain why the universe is lopsided with more matter instead of antimatter. Researchers at DZero, an experiment at the Tevatron particle accelerator at Fermilab in Batavia, Ill., have found the largest source of CP violation yet discovered, courtesy of Bs mesons, which can transform themselves into their own antiparticle and back again. B mesons are created in proton-antiproton collisions and decay into muons or antimuons. More muons are counted after a collision indicating that something favors the production of normal matter over antimatter. More

It's magnetic moment season: Measuring various g-factors
Uncertain Principles    Share    Share on FacebookTwitterShare on LinkedinE-mail article
There have been recent reports of g-factor measurements of an electron in silicon ions and protons spin flips. Chad Orzel is dissatisfied with the media reporting of the proton flip result, so he takes a crack at explaining the physics in a Q&A format. More

How to make a superlens from a few cans of cola
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers in France have managed to assemble an acoustic metamaterial from a few multipacks of cola cans. Arranged in a grid, the drinks cans act as a superlens for sound, focusing acoustic waves into much smaller regions than their meter-long wavelengths typically allow. More

Stardust in our backyard provides new clues to galaxy evolution
Science Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
New data from the European Space Agency's Herschel Space Observatory have revealed surprisingly large amounts of cold dust in the remnant of the famous supernova SN1987A. With this discovery, astronomers confirm that supernovae are able to produce significant quantities of dust over very short time scales. This may help explain previous observations, by Herschel and other observatories, of abundant dust in the early universe as seen in high-redshift galaxies. More



Where should the Square Kilometer Array be built?
International SKA Office    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The SKA Founding Board recently unveiled the process and timeline for selection of the host site for the telescope, either Africa or Australia. "Selection of the host site for the SKA will be made in terms of characteristics for the best science as well as the capability and cost of supporting a very large infrastructure, taking the political and working environment into account," Richard Schilizzi said, director of SKA. You can have your say at PhysicsWorld.com's Facebook poll. More

South African Minister of Science and Technology visits ALICE
ALICE Matters    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The South African Minister of Science and Technology, Naledi Pandor, visited CERN June 22. The minister was accompanied by a delegation from her department and the South African mission to Switzerland. This event is the latest in a series of official visits of the South African government to CERN, in order to support the South African participation in CERN, as well as to investigate methods of knowledge transfer and other forms of cooperation.

article
With NSF having canceled its participation in the project, and the Department of Energy scrambling to find dollars to continue it, the Deep Underground Science and Engineering Laboratory got a much needed endorsement by a "blue-ribbon" panel convened the National Academies. Physicists hope to build a trio of exquisitely sensitive particle physics experiments 1,480 meters down, where the overlying stone would block out most of the radiation from cosmic rays. More

Lament the gap — Neil deGrasse Tyson on what's next for the space program
Marketplace    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Neil deGrasse Tyson says we shouldn't be lamenting the end of the space shuttle program. Rather we should instead be lamenting the fact that there is nothing to replace it. "What I would require for NASA," he says, "is that the budget doubles from 4/10s of a percent of your tax dollar to 8/10s of a percent of your tax dollar. More

New report offers roadmap for success in K-12 STEM education
Science Daily    Share    Share on
FacebookTwitterShare on LinkedinE-mail article
The NRC report, "Successful K-12 STEM Education," is a response to a request from U.S. Congressman Frank Wolf to identify the characteristics of highly successful K-12 schools and programs in science, technology, engineering and mathematics. The report offers two sets of recommendations, geared for schools and districts, and for state and national policymakers. The recommendation of elevating science to the same level of importance as reading and mathematics would seem to be consistent with NSBP's call for a focus on equity and access to formal physics classes.

The U.S. Agency for International Development and the NSF are undertaking a new venture to build partnerships with developing world institutions at the same time they pursue their respective missions to provide foreign assistance and to support science and research in the United States. Top agency leaders who announced this collaboration July 7 have hopes that the partnership may lead to solutions to development challenges that seem hugely daunting today. More

NSB seeks input on proposed merit review criteria revision and principles
NSBP    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Over the past year, the National Science Board has been conducting a review of the NSF's merit review criteria (Intellectual Merit and Broader Impacts). At the board's May meeting, the NSB Task Force on Merit Review proposed a revision of the two merit review criteria, clarifying their intent and how they are to be used in the review process. In addition, the task force identified a set of important underlying principles upon which the merit review criteria should be based. We now seek your input on the proposed revision and principles.
