Lee Rannals for redOrbit.com – Your Universe Online Researchers at the Large Hadron Collider (LHC) are on the verge of squashing an important physics theory known as supersymmetry (SUSY). The Supersymmetry theory helps to explain some of the inconsistencies in the traditional theory of subatomic physics. New observations reported at the Hadron Collider Physics conference in Kyoto, Japan are not consistent with many of the most likely models of the theory. Researchers had been...
Brett Smith for redOrbit.com - Your Universe Online An international team of researchers has created ionized xenon atoms so positively charged that scientists involved in the study are now saying the existing theories need to be reexamined. Using the world’s most powerful laser, the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory at Stanford University, the physicists were able to kick out up to 36 electrons from a xenon...
Alan McStravick for redOrbit.com - Your Universe Online Just outside of Geneva, Switzerland is one of the world’s foremost ongoing experiments to explore not only the smallest components of our universe, but, in so doing, to understand the vastness of space, our universe as a whole, and just how it came into being. The Large Hadron Collider (LHC) at CERN is an approximately 17-mile-long ring buried some 330 feet underground which spans the border between Switzerland and France. The...
Researchers at the Department of Energy's Oak Ridge National Laboratory have found that nitrogen atoms in the compound uranium nitride exhibit unexpected, distinct vibrations that form a nearly ideal realization of a physics textbook model known as the isotropic quantum harmonic oscillator. In the experiment on the uranium nitride crystal -- with each of the light nitrogen atoms centered in a cage of heavier uranium atoms -- neutron scattering at ORNL's Spallation Neutron Source (SNS)...
Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) is looking into how Moon and Martian soil could be used to help shield astronauts in space. ESA is teaming up with Germany's GSI particle accelerator for a two-year project in assessing promising materials for shielding future astronauts en route to the Moon, an asteroid or Mars. “We are working with the only facility in Europe capable of simulating the high-energy heavy atomic nuclei found in...
The search for dark matter runs deep with physicists Blas Cabrera and Bernard Sadoulet, who have chased this mystery far underground and will be recognized for their work as joint recipients of the 2013 W.K.H. Panofsky Prize in Experimental Particle Physics.

The University of Notre Dame has received a five-year, $6.1 million award from the National Science Foundation to support the continuation of the nationwide QuarkNet program, which uses particle physics experiments to inspire students and provide valuable research, training and mentorship opportunities for high school teachers. Through the QuarkNet program, physicists at Notre Dame, Fermilab and 50 other research institutions will continue to mentor teachers in research experiences,...
April Flowers for redOrbit.com - Your Universe Online An international group of researchers, led by the University of Granada, has measured the effects of layers on super-heavy elements, providing useful data on the nuclear structure of these as yet undiscovered elements in nature. The results, reported in Science, might prove useful in locating the "Island of Stability." The team measured the isotopes of nobelium (No) and lawrencium (Lr) using a particle accelerator at the GSI...
BLOOMINGTON, Ind., Sept. 11, 2012 /PRNewswire-iReach/ -- PartTec, Ltd., an Indiana-based manufacturer of radiation detection technologies, has signed an agreement to manufacture and market a neutron detector system that may help researchers identify the underlying causes of human diseases. Using the Neutron-Sensitive Anger Camera developed by the Department of Energy's Oak Ridge National Laboratory, biologists can study a wider variety of proteins. Insight gained from studying these...
AMSTERDAM, September 10, 2012 /PRNewswire/ -- Physics Letters B, Elsevier's flagship journal in high energy physics, announced today that the observations of the long-sought Higgs particle, hailed as one of the greatest scientific discoveries of all time, have been published. The papers: "Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC" [http://www.sciencedirect.com/science/article/pii/S0370269312008581 ] and "Observation of a new particle...

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...
Physics is the scientific study of matter and its motion through space/time and its derivitives, including energy and force. It is generally the analysis of nature and is conducted to help us understand how the universe behaves. Physics comes from the Greek word physis, meaning "nature". It is among the oldest academic disciplines, and perhaps the oldest pertaining to astronomy. Physics has been considered synonymous with philosophy, chemistry, mathematics, and biology for more than 2000...
WIMP -- In astronomy, WIMPs, or weakly interacting massive particles, figure into one explanation of the dark matter problem. The particles are called "weakly interacting" because they seem not to have much interaction with normal matter (electrons, protons, and neutrons) other than gravitational attraction (thus "massive"). Assuming that there are Weakly Interacting Massive Particles, these particles would then fall out of equilibrium with the universe when they are non-relativistic....
Strange Matter -- Strange matter (also known as quark matter) is an ultra-dense phase of matter that is theorized to form inside particularly massive neutron stars (which are then known as "strange stars" or "quark stars"). It's theorized that when neutronium is put under sufficient pressure due to the gravitation of a large neutron star, the individual neutrons break down and their constituent quarks form strange matter. Strange matter is composed of strange quarks bound to each...
Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...
