Black-hole like effect in nanotube and the possibility of new ma

(PhysOrg.com) -- “For the first time, fields of study relating both to cold atoms and to the nanoscale have intersected,” Lene Vestergaard Hau tells PhysOrg.com . “Even though both have been active areas of research, cold atoms have not been brought together with nanoscale structures at the single nanometer level.
Quarks, the elementary particles that make up protons and neutrons, have been notoriously difficult to nail down -- much less weigh -- until now. A research group co-founded by Cornell physics professor G. Peter Lepage has calculated, with a razor-thin margin of error, the mass of the three lightest and, therefore, most elusive quarks: up, down and strange.
Masses of common quarks are revealed
Glasgow scientists predict mass of new particle
(PhysOrg.com) -- A team of physicists from the University of Glasgow has predicted the mass of a new particle which would help explain one of the fundamental forces of the universe.MIT physicist to describe strange world of quarks, gluons
One of the great theoretical challenges facing physicists is understanding how the tiniest elementary particles give rise to most of the mass in the visible universe. Tiny particles called quarks and gluons are the building blocks for larger particles such as protons and neutrons, which in turn form atoms. However, quarks and gluons behave very differently than those larger particles, making them more difficult to study.
Latest Supercomputer Calculations Support the Six-Quark Theory
A new calculation, reported in the January 25, 2008 issue of Physical Review Letters , confirms the six-quark theory of particle-anti-particle asymmetry.
For a brief instant, it appears, scientists at Brook haven National Laboratory on Long Island recently discovered a law of nature had been broken.

From two-trillion-degree heat, researchers create new matter --
An international team of scientists studying high-energy collisions of gold ions at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator located at the U.S. Department of Energy’s Brookhaven National Laboratory, has published evidence of the most massive antinucleus discovered to date.
Physicist proposes method to teleport energy
Japanese physicist Masahiro Hotta of Tohoku University has explained the energy teleportation scheme in a recent study posted at arxiv.org, called “Energy-Entanglement Relation for Quantum Energy Teleportation.” Previously, physicists have demonstrated how to teleport the quantum states of several different entities, including photons, atoms, and ions.
Long-distance quantum communication gets closer as physicists in
Physicists Thierry Chaneličre of the Laboratoire Aimé Cotton - CNRS in Orsay, France, and his coauthors have published their results of the new light storage method in a recent issue of the New Journal of Physics .As astrophysicists Robert Reasenberg and James Phillips explain in a series of papers, their proposed test is aimed at a very small measurement uncertainty of 10 -16 after averaging the results of eight separate free fall drops.
