The article discusses the teams of physicists at A Toroidal LHC Apparatus (ATLAS) and the Compact Muon Solenoid (CMS), two detectors at the Large Hadron Collider (LHC) of the European Organization for Nuclear Research (CERN) which are being used to search for the Higgs boson and study supersymmetry (SUSY). The ATLAS and CMS collaborations both involve thousands of scientists who compete with each other to make discoveries. Physicists including Martijn Mulders, Sara Strandberg, and Maria Spiropulu discuss competition between groups, concerns about unethical behavior, and the culture of CMS and ATLAS. INSET: U. S.

CTBTO/SCIENCE SOURCE From 1966 to 1974, France blew up 41 nuclear weapons in above-ground tests in French Polynesia, the collection of 118 islands and atolls that is part of France. PHOTO (COLOR): From 1966 to 1974, France conducted 41 above-ground test of nuclear weapons on the Moruroa atoll, including this one of a 0.9-megaton giant in the Licorne test on 3 July 1970.

The article discusses the European Organization for Nuclear Research's (CERN) Large Hadron Collider (LHC), which is the world's highest-energy atom smasher. CERN spent a year repairing the LHC as a result of various technical glitches resulting in a damaging electrical failure. Topics include an overview of how the LHC smashes atoms by accelerating particles to near light speed and the use of superconducting synchrotron magnets in place of conventional copper magnets. An overview of the similar problems with the Tevatron particle accelerator at the U.S. Fermi National Accelerator Laboratory and Germany's Hadron Electron Ring Accelerator (HERA) are presented.

The article focuses on research into quark-gluon plasma and the development of a quark-gluon plasma model. It states that the only two atom smashers that can generate quark-gluon plasma are the Relativistic Heavy Ion Collider (RHID) at Brookhaven National Laboratory in New York and the Large Hadron Collider in Europe, and comments that the RHID is dedicated to studying quark-gluon plasma. It mentions the U.S. Department of Energy may be forced to shut down the RHIC due to limited funding. It comments that quark-gluon plasma is generated when two heavy nuclei are smashed together to form a plasma of quarks, antiquarks, and gluons before it cools into ordinary particles.

The article discusses the start of the particle collider the Large Hadron Collider (LHC) which became damaged when a splice in the superconducting electrical line melted, resulting in a chain reaction of mechanical failures. Topics include the discovery by particle physicists at the European Organization for Nuclear Research (CERN), which houses the LHC, of flaws in the repaired electrical connections, the costs of the delays, and how the faulty electronics will limit the accelerator's energy output. Also discussed is the seriousness of the flaw in the copper surrounding the splices and a brief description of the ribbonlike superconductor that runs within the copper cladding.

The article discusses a report by officials at the European Organization for Nuclear Research (CERN) describing how to they will get the Large Hadron Collider (LHC) working. Topics include an overview of the LHC's breakdown which occurred nine days after scientists circulated protons through its electromagnetic column, a brief description of the damage to the LHC magnets, and how scientists will correct any design flaws that caused the magnets to overheat.

The article discusses data from an atom smasher in the U.S., called the Tevatron, located at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, that hints at the detention of Higgs bosons, which are subatomic particles that hold the key to how all particles get their mass. Reportedly the hints correlate with those seen by researchers working with Europe's Large Hadron Collider (LHC). Differences in data between the Tevatron and the LHC are discussed.

The article discusses speculation that research performed at the Large Hadron Collider will indicate the existence of the Higgs Boson elementary particle. The project has collected 2 years of data on particle collisions, and researchers hope that evidence of particles in the expected mass range of the Higgs Boson will be detected.

The article reports that despite hints of the existence of the Higgs boson by researchers working with the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN), near Geneva, Switzerland, there are no signs of particles beyond those in the standard model of known particles. Topics include concern that the LHC may not find any new particles and the importance of finding Higgs bosons.

The article discusses the Large Hadron Collider (LHC) located at the European Organization for Nuclear Research (CREN) in Switzerland. Officials at CERN have reduced the amount of energy used to smash atoms in an effort to prevent overloading the LHC's faulty electrical connections which are made from thousands of superconducting magnets. An overview of the Tevatron collider located at the U.S. Fermi National Accelerator Laboratory in Batavia, Illinois, which is the LHC's rival, is presented.

The article discusses the future of the European Synchrotron Radiation Facility (ESRF) which is an x-ray source in Grenoble, France. The facility received 177 millions euros for an upgrade. Topics include a brief overview of the sciences the ESRF supports including materials science and structural biology and how the money will be spent including creation of eight nanometer-sized x-ray beams and improved instrumentation.

The article reports on the collaboration of the world's three large gravitational wave detectors in measuring the minuscule stretching of space. The Virgo detector near Pisa, Italy will share data with the Laser Interferometer Gravitational-Wave Observatory (LIGO), which has detectors in Livingston, Louisiana, and Handfor, Washington. On the other hand, LIGO collaborates with GEO600, a detector near Hannover, Germany. The said collaboration was agreed by funding agencies in the U.S., Italy and France.
