Scientists Use Neutrons To Search For Dark Energy
2014-04-17 10:13:42

Vienna University of Technology With neutrons, scientists can now look for dark energy in the lab All the particles we know to exist make up only about five per cent of the mass and energy of the universe. The rest – "Dark Matter" and "Dark Energy" – remains mysterious. A European collaboration led by researchers from the Vienna University of Technology has now carried out extremely sensitive measurements of gravitational effects at very small distances at the Institut Laue-Langevin...

Higgs Boson Junior? Particle Physicist Theorizes There Are Particles Even Smaller
2014-03-22 06:37:21

redOrbit Staff & Wire Reports - Your Universe Online It’s been just over one year since the discovery of the Higgs boson was all but confirmed, but researchers from the University of Southern Denmark’s Center for Cosmology and Particle Physics Phenomenology (CP ³ - Origins) now believe that there might be particles even smaller that have yet to be discovered. According to particle physicist and associate professor Thomas Ryttov, those particles have yet to be detected. However,...

Quarks In The Mirror
2014-02-06 12:22:26

DOE/Thomas Jefferson National Accelerator Facility From matching wings on butterflies to the repeating six-point pattern of snowflakes, symmetries echo through nature, even down to the smallest building blocks of matter. Since the discovery of quarks, the building blocks of protons and neutrons, physicists have been exploiting those symmetries to study quarks' intrinsic properties and to uncover what those properties can reveal about the physical laws that govern them. A recent...

Researchers have made the first experimental determination of the weak charge of the proton in research carried out at the Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab). The results, accepted for publication in Physical Review Letters, also include the determinations of the weak charge of the neutron, and of the up quark and down quark. These determinations were made by combining the new data with published data from other experiments. Although these...

New Technique Could Reveal High Detail Of Earth's Composition
2013-02-22 10:50:16

April Flowers for redOrbit.com - Your Universe Online In a new study recently published in the journal Science, a research team from Amherst College and The University of Texas at Austin has described a new technique that might one day reveal the composition and characteristics of the deep Earth in never before seen detail. There's just a tiny little hitch in the new technique. It relies on a fifth force of nature that has not yet been detected. Current physics theories hold that there...

A cornerstone of physics may require a rethink if findings at the National Institute of Standards and Technology (NIST) are confirmed. Recent experiments suggest that the most rigorous predictions based on the fundamental theory of electromagnetism–one of the four fundamental forces in the universe, and harnessed in all electronic devices–may not accurately account for the behavior of atoms in exotic, highly charged states. The theory in question is known as quantum...

A new experiment proposed by physicists at the National Institute of Standards and Technology (NIST) may allow researchers to test the effects of gravity with unprecedented precision at very short distances"”a scale at which exotic new details of gravity's behavior may be detectable.Of the four fundamental forces that govern interactions in the universe, gravity may be the most familiar, but ironically it is the least understood by physicists. While gravity's influence is...

Perimeter Institute Faculty member Jaume Gomis has won an Early Researcher Award from the Ministry of Research and Innovation (MRI) of Ontario. Early Researcher Awards help promising, recently-appointed Ontario researchers build their research teams of graduate students, postdoctoral fellows, research assistants and associates. The goal of the program is to improve Ontario's ability to attract and retain the best and brightest research talent. The $150,000 award will be used to support Dr....

Scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory in the US, have performed sophisticated laser measurements to detect the subtle effects of one of nature's most elusive forces - the "weak interaction". Their work, which reveals the largest effect of the weak interaction ever observed in an atom, is reported in Physical Review Letters and highlighted in the August 10th issue of APS's on-line journal Physics (physics.aps.org).Along with gravity,...

University of Nevada, Reno team findings to be published in Physical Review Letters article In a forthcoming Physical Review Letters article, a group of physicists at the University of Nevada, Reno are reporting a refined analysis of experiments on violation of mirror symmetry in atoms that sets new constraints on a hypothesized particle, the extra Z-boson. Andrei Derevianko, an associate professor in the College of Science's Department of Physics, who has conducted groundbreaking research to...


Word of the Day
barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
