Particle physics is at a turning point — String theory may be connected to the real world
Nature    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Two quite different detectors at the LHC see a signal of some significance at about the same mass. And they both see the expected signals in two or more channels. This could represent a profound turning point in the quest for a fundamental unified theory of the physical world. But a major and unexpected clue to the future offered by the CERN discovery is that the reported Higgs boson signal seems to behave as if it were a "standard-model Higgs boson." Under the Standard Model, this should not be possible. However, when the standard model is extended to a supersymmetric theory, the resulting theory is realistic. Actually the same string theory (more exactly, M-theory) that predicts the Higgs mass correctly also predicts that a spectrum of particle superpartners, and some of their associated signals should be discovered at the LHC.

DOE's Intensity Frontier Workshop packed with ideas and people
Symmetry Breaking Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The Fundamental Physics at the Intensity Frontier Workshop was set up to survey existing research and future scientific possibilities in this area, and to gauge the level of interest from the physics community. Physicists spent three days in six working groups listening to more than 100 presentations identifying promising research areas that use neutrinos, nucleons, nuclei, heavy quarks, charged leptons and exotic particles such as axions. The consensus was that a host of experiments have the potential to answer the biggest questions: How did the universe begin? What is it made of? How does it work? How did we come to exist? Answers from this research could aid studies in cosmology, nuclear physics and other areas of particle physics. More

STEM literacy beyond STEM occupations
Diverse Issues in Higher Education    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The Georgetown Center on Education and the Workforce recently released a new publication simply titled STEM. Beyond just another depiction of why we need more STEM graduates to strengthen our workforce (although the authors do a stellar job at breaking down this argument), the authors do something more. The report gets into the tricky territory of defining just why STEM literacy is important both inside and outside STEM fields and sheds light on how those who seek to enter STEM fields — as well as those who are successful in doing so — eventually divert from the STEM pathway.

Scaling down frequency
Nature Photonics    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Although directly sampling an electric field at optical frequencies is impossible owing to the frequency limitation of electronic sampling devices, indirect sampling can be achieved through heterodyne processes that generate beat notes in the radiofrequency domain. The Delfyett group at the University of Central Florida has reported in the Journal of Lightwave Technology the use of frequency combs as local oscillators to downconvert and compress optical signals through multiheterodyne detection, a process by which two combs that share an optical reference are mixed to deduce the effect of a medium on the signal comb. Delfyett, et al.'s design achieved spectral compressions of three and four orders of magnitude, respectively, for phase-modulated light and mode-locked pulses. The resulting RF interference patterns can also be used for high-resolution white-light spectral interferometry. More

Star explosion leaves behind a rose
Space Ref    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Astronomers using the Wide-field Infrared Survey Explorer have revealed an IR image of the remnants of a supernova explosion that occurred about 3,700 years ago. The remnants, called Puppis A and pronounced PUP-pis, were formed when a massive star ended its life in an extremely bright and powerful explosion. Puppis A includes glowing dust and gas clouds, and an inexplicably fast spinning neutron star that has been detected in the X-ray and IR but not in the radio region. More

Caltech chemists propose explanation for superconductivity at high temperatures
California Institute of Technology    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Over the last four years, William Goddard and Jamil Tahir-Kheli have been building a hypothesis that explains what makes cuprates superconduct. They have been working with a cuprate in which strontium atoms are the "dopant atoms," replacing lanthanum atoms.

Based on modern quantum-mechanical calculations, Goddard and Tahir-Kheli found that each dopant atom creates a four-center hole on the copper atoms surrounding the strontium, a unit they refer to as a "plaquette." Electrons within the plaquettes form tiny pieces of metal, while those outside the plaquettes are insulating and behave like magnets. Their hypothesis is that when enough dopant atoms are added, the plaquettes are able to create a percolating pathway that allows electrons to flow all the way through the material. The magnetic electrons outside the plaquettes can interact with the electrons traveling through the plaquette pathway, and it is this interaction that leads to the electron pairing — the slight attraction between electrons — that in turn results in superconductivity.

Earlier this year, in paper published in the Journal of Physical Chemistry Letters, Goddard and Tahir-Kheli took their hypothesis a step further by accounting for the so-called pseudogap phase seen in cuprate superconductors.

Metal undergoes novel transition under extreme pressure
Carnegie Institution for Science    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Under extreme pressures and temperatures similar to those at the depth where the Earth's innermost two layers meet, iron oxide, one of the main materials of the Earth's interior, exhibits a never-before-seen transition in its electrical conductivity. But researchers at the Carnegie Institution for Science report in a forthcoming paper in Physical Review Letters that the conductivity transition is not accompanied by a structural transition. The finding could have implications for our as-yet incomplete understanding of how the Earth's interior gives rise to the planet's magnetic field. More

Unlocking the details to how volcanoes work
Live Science    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In volcanoes is the magma conduit, also known as a magma channel, a "soda straw" that taps a deep magma reservoir? Or is it a pathway made up of interconnected cracks? And how much force is associated with these eruptions? What is the role of magmatic gases in driving eruptions? To answer these questions Greg Waite and his research team at Michigan Technological University record earthquakes, low-frequency sound and gas emissions from high on the flanks of active, but relatively gentle volcanoes.
