New tests confirm the results of OPERA on the neutrino velocity
Interactions    Share    Share on FacebookTwitterShare on LinkedinE-mail article
New tests conducted at the Gran Sasso National Laboratory of INFN by the OPERA Collaboration, with a specially set up neutrino beam from CERN, confirm so far the previous results on the measurement of the neutrino velocity. The new tests seem to exclude part of potential systematic effects that could have affected the original measurement. On Nov. 17 the OPERA Collaboration submitted the paper on the neutrino velocity measurement to the Journal of High Energy Physics, and in parallel to ArXiv. More

LHb result hints at matter-antimatter bias
Science Now    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers on the LHCb experiment are reporting that the relative decay rates between D0 particles and antiparticles differ by 0.8 percent. If confirmed, this level of charge-parity violation would at least eight times as high as the Standard Model allows, and could help explain why there is still "stuff" in the universe. More

NSF FY12 budget signed into law
American Institute of Physics    Share    Share on FacebookTwitterShare on LinkedinE-mail article
President Barack Obama has signed into law the FY12 budget for the National Science Foundation that provides for a 2.5 percent increase over the previous year's budget. The agency's overall budget will be slightly over $7 billion USD, with $5.7 billion for research and related activities, and $167 million for major research equipment and facilities construction. These are 2.8 and 42.7 percent increases over last year's budgets, respectively. The agency's Education and Human Resources Directorate is slated for a 3.7 percent decrease. More

Understanding thermal effects in spintronics
American Physical Society    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The 2008 discovery of the spin-Seebeck effect has pushed the discipline of "spin caloritronics" into the spotlight, and has opened up a new route of exploiting the spin dimension in electronic transport. As the effect has been observed in a variety of materials, interesting complications have emerged in samples of 2-D films on substrates. Writing in Physical Review Letters, a team of physicists have reported observation of the spin-Seebeck effect in Permalloy films with and without a substrate. Apparently the substrate can introduce its own thermodynamics that can overpower that of the film to produce a composite effect. More

One cool demo: Magnetic field flips miniature origami
American Physical Society    Share    Share on FacebookTwitterShare on LinkedinE-mail article
VideoBriefIn 2007 a French team produced structures interesting in physics and in art by placing droplets of water on top of thin rubbery membranes, and then allowing the water to evaporate. As the liquid evaporated, its surface tension tugged the membrane closer around the water's decreasing volume, until the remaining liquid was completely encapsulated inside a sphere, tetrahedron or some other shape. Now they have replaced the water with a ferrofluid, and in a magnetic field they can produce some interesting structures and kinematics. More

Proof found for unifying quantum principle
Nature    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Twenty-five years ago John Cardy proposed a conjecture, called the a-theorem, that says that the number of ways in which quantum fields can be energetically excited "a" is always greater at high energies than at low energies. Put another way by Matt Strassler, a quantum field theory has a calculable quantity, called "a" for historical reasons, that helps characterize it. The conjecture is that if you take any quantum field theory, and study the phenomena that it exhibits at longer and longer distance you will find that "a" always decreases. A proof the theorem was recently proposed by Zohar Komargodski and Adam Schwimmer of the Weizmann Institute of Science that is gradually gaining acceptance. More



Making light out of virtual photons
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
An international team of physicists have used the dynamical Casimir effect to force a mirror to make its own light rather than simply reflecting the light around it. The experimental result reported in Nature uses quantum fluctuations in which virtual subatomic elementary particle pairs continuously pop in and out of existence in a vacuum. These quantum fluctuations were harnessed using a SQUID device to create the electrical equivalent of an ultrafast mirror to convert virtual photons into real electromagnetic radiation via the dynamical Casimir effect.

NASA probe data show evidence of liquid water on icy Europa
Astronomy    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Data from a NASA planetary mission have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter's moon, Europa. The data suggest there is significant exchange between Europa's icy shell and the ocean beneath. This information could bolster arguments that Europa's global subsurface ocean represents a potential habitat for life elsewhere in our solar system. The findings are published in Nature. More

President Obama honors physicist Solomon Bililign with Presidential Award for science mentoring
Tadias    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Solomon Bililign, a professor at North Carolina A&T Statue University, and director of the NOAA-ISET Center there, has been selected to receive the Presidential Award for Excellence in Science, Mathematics, and Engineering Mentoring. These awards are bestowed by the White House to individuals and organizations to recognize the crucial role that mentoring plays in the academic and personal development of students studying science and engineering — particularly those who belong to groups that are underrepresented in these fields. Professor Bililign is co-chair of the NSBP section on Earth and Planetary Systems Sciences. More

Peter Delfyett elected Fellow of APS
American Physical Society    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Dr. Peter Delfyett, the current president of the National Society of Black Physicists, has been elected Fellow of the American Physical Society, "For pioneering contributions to the understanding of the physics and implementation of ultrafast diode lasers."

Delfyett is the Trustee Chair and professor in the College of Optics and Photonics/CREOL at the University of Central Florida. He also holds appointments in the electrical engineering and physics departments there. His research group is primarily working on high-powered, ultra-short pulsed, multiwavelength mode-locked semiconductor lasers. Earlier this year his group demonstrated line-by-line pulse shaping of optical comb lines with updates to the pulse shape on the time scale of the pulse period.
