Reports that a group of researchers at the Stanford Linear Accelerator Center (SLAC) were unsuccessful in their attempt to find millicharged particles. Information on the quantization of electric charge; Comments from SLAC theorist, Michael Peskin; What is the reason for using plastic scintillation; Increase in the rate of millicharge production.

The article highlights a study on bottomonium (B) ground state. It explores the founding of bottomunium ground state based on the study conducted by PEPII electron-position collider at Stanford Linear Accelerator Center and continued by BaBar collaboration. BaBar collaboration, which operated the so-called B-factory's detector, decided it would be useful to run the collider at several collision energies below the threshold for making B pairs. Details on the result of the study are discussed.

Provides information on other planets called new neptunes. Description of the planet found by McArthur's McDonald Observatory team led by Butler and Geoff Marcy at the University of California in Berkeley; Information on the new neptune orbiting Gliese 436; Definition of astrometry.

Discusses the announcement from Lawrence Berkeley National Laboratory (LBNL) in California that one of its physicists was disciplined for scientific misconduct for allegedly fabricating evidence relating to chemical element 118 and its decay sequence. Discussion on the retraction made by LBNL; Reason for the attention given to the heavy-element experiment which was announced in June 1999; Concerns that led to formal investigation of the allegations.

Features the Landers earthquake which struck the Mojave Desert on June 28, 1992. Magnitude; Evidence of remote triggered secondary tremors as reported at 14 locations; Immediate occurrence of secondary quakes. INSET: Stirring things up in waste tank at Hanford..

The article reports that Persis Drell became the director of the Stanford Linear Accelerator Center (SLAC) in December 2007. Drell was a professor of physics at Cornell University for 14 years before going to SLAC in 2002 to be director of the lab's research division. At Cornell she was the deputy director of the university's laboratory for nuclear studies and chair of its synchrotron-radiation committee.

Reports that accelerator physicists at the Final Focus Test Beam, a new facility at the Stanford Linear Accelerator Center, have managed to squeeze the vertical width of a high-energy electron beam down to 75 nanometers. Smaller than the focal spots of the 50-GeV electron and positron beams of the Stanford Linear Collider.
