Direct measurements allow detailed look at how quarks of different flavors contribute to spin Scientists hoping to unravel the mystery of proton spin at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, have a new tool at their disposal "” the first to directly explore how quarks of different types, or "flavors," contribute to the overall spin of the proton. The technique,...

After less than three weeks of heavy-ion running, the three experiments studying lead ion collisions at the LHC have already brought new insight into matter as it would have existed in the very first instants of the Universe's life. The ALICE experiment, which is optimized for the study of heavy ions, published two papers just a few days after the start of lead-ion running. Now, the first direct observation of a phenomenon known as jet quenching has been made by both the ATLAS and CMS...

The Large Hadron Collider (LHC) has taken new steps by smashing together lead ions instead of protons to create a "mini-Big Bang." Scientists working at the particle smasher achieved the feat on November 7. Experts working with the LHC created temperatures a million times hotter than the center of the sun. The LHC lies under the French-Swiss border near Geneva in a 16-mile long circular tunnel. The world's highest-energy particle accelerator has been colliding protons in search for the...

At the Large Hadron Collider at CERN protons crash into each other at incredibly high energies in order to 'smash' the protons and to study the elementary particles of nature "“ including quarks. Quarks are found in each proton and are bound together by forces which cause all other known forces of nature to fade. To understand the effects of these strong forces between the quarks is one of the greatest challenges in modern particle physics. New theoretical results from the Niels Bohr...

Data suggest symmetry may 'melt' along with protons and neutrons Scientists at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator at the U.S. Department of Energy's Brookhaven National Laboratory, report the first hints of profound symmetry transformations in the hot soup of quarks, antiquarks, and gluons produced in RHIC's most energetic collisions. In particular, the new results, reported in the journal Physical Review Letters, suggest that "bubbles"...

Force of interaction between magnetic particles grows stronger with increasing distance An experiment has confirmed that spinons, particle-like magnetic excitations, can be confined in a magnetic insulator similar to the way elementary quarks are confined within individual protons and neutrons. The finding, in a well-described magnetic system, may offer new ways to explore Quantum Chromodynamics, the theory that describes the fundamental interactions of quarks. The observations of spinon...

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....

Duke and Brookhaven examine free-flowing 'exploding cigars' Several years after Duke University researchers announced spectacular behavior of a low density ultracold gas cloud, researchers at Brookhaven National Laboratory have observed strikingly similar properties in a very hot and dense plasma "fluid" created to simulate conditions when the universe was about one millionths of a second old. The plasma was formed at a colossal 2 million degrees Kelvin temperatures within Brookhaven's...

Two Japanese scientists and a Japanese-born American have been awarded the 2008 Nobel Prize in physics for their work with subatomic particles which provided new insights into the nature of matter. The Royal Swedish Academy of Sciences announced the winners - Yoichiro Nambu, Makoto Kobayashi and Toshihide Maskawa "“ on Tuesday. American Yoichiro Nambu, 87, of the University of Chicago, won half of the prize for the discovery of a mechanism called spontaneous broken symmetry in...

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
