CERN plans Dec. 13 news conference on Higgs result
BBC News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The ATLAS and CMS collaborations will present independent analyses of data collected by the LHC's experiments up to this October at a seminar in Geneva on Dec. 13. The respective teams have not had the time to combine their results, and will not be comparing their results beforehand to avoid biasing their interpretation of their own data. While the definitive finding of the Higgs boson has not been achieved yet, the search for it has converged upon a small window of masses. More

Borexino observes neutrinos with new precision
msnbc    Share    Share on FacebookTwitterShare on LinkedinE-mail article
An international team of researchers at the Borexino experiment have reported in Physical Review Letters new data on solar neutrinos collected with unprecedented precision. The new data from Borexino on lower-energy neutrinos confirm that solar neutrino oscillations are energy-dependent — lower-energy solar neutrinos are more likely to come in the electron flavor than higher-energy ones. Overall, these new findings help exclude more exotic explanations for neutrino oscillations. The hope remains that Borexino could detect a new kind of neutrino from the sun, one that could help shed light on the mystery of these particles. More



Physicists propose search for fourth neutrino
Physorg.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Physicists know that neutrinos (and antineutrinos) come in three flavors: electron, muon and tau; and have watched them oscillate back and forth between flavors. A proposed fourth neutrino, the so-called "sterile neutrino", would explain some anomalous results, but would be particularly difficult to detect. In their study published in a recent issue of Physical Review Letters, Michel Cribier, et al., have proposed an experiment that would, according to them, unambiguously test whether or not a fourth flavor of neutrino really exists. If it does, then it would have huge implications not only for neutrino science and possibly dark matter, but also for understanding building blocks of matter overall. More

Newfound alien planet is hot enough to melt iron
National Optical Astronomy Observatory    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Astronomers have found an alien planet not much bigger than Earth, but so blisteringly hot that life has no shot of gaining a foothold there. The exoplanet is 1.6 times bigger than Earth, but orbits so close to its parent star that astronomers estimate that its surface temperature to be about 2960 degrees Fahrenheit. The planet was found using NASA's Kepler Space Telescope, and was further studied using telescopes at Arizona's Kitt Peak National Observatory. More



Radio wave excess could point to dark matter
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
An excess of radio waves recorded by a balloon-borne experiment could be a signal of dark matter, a new study suggests. Data from the ARCADE mission seem to fit in with other direct, recently reported evidence for dark matter, although some believe they may have a mundane explanation. More



Searching for dark matter in exoplanet data
American Physical Society    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Our galaxy could be filled with asteroid-size black holes that presumably formed shortly after the big bang. If they exist in large numbers, these so-called primordial black holes would serve as the dark matter that keeps stars gravitationally glued inside galaxies. None of these primordial black holes have been detected so far, but a new theoretical analysis described in Physical Review Letters demonstrates that a current planet-hunting mission is well placed to search for them.

'Phonitons' predicted in crystal lattices
American Physical Society    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Vibrations in a crystal can combine with an electron in a new way to form a hybrid quantum entity, according to a team of theorists publishing in Physical Review Letters. They call it a "phoniton", a particle that combines a phonon — the quantum form of vibrations — with a matter excitation, such as an electron that transits between two levels. The team also proposes a nanostructure that would support this quantum state and allow it to be observed. Because the new quantum particle represents a coupling of an electron with a localized vibration, the researchers say it could serve in sensors or as a link to quantum computing devices. More

Making a biomimetic light-harvesting antenna from scratch
Washington University in St. Louis    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A team at Washington University in St. Louis's Photosynthetic Antenna Research Center (PARC) has just succeeded in making a crucial photosystem component — a light-harvesting antenna — that is modeled on the chlorosome found in green bacteria. These synthetic chlorosomes don't have a protein scaffold. Instead the pigment molecules self-assemble into a structure that supports the rapid migration of excitation energy. The next steps are to cast the assemblies on a surface, and to better understand the exiton dynamics in those 2-D systems. More

Biocompatible graphene transistor array reads cellular signals
EurekAlert    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Reported in Advanced Materials, researchers have demonstrated, for the first time, a graphene-based transistor array that is compatible with living biological cells and capable of recording the electrical signals they generate. The transistor could record signals with high spatial and temporal resolution, and even followed hormone-induced changes in cellular electrical activity. The analysis of the recorded cell signals and the electronic noise of the transistors confirm that graphene transistors surpass state-of-the-art devices for bioelectronic applications. More
