Image of the Week - Traffic Information Grid An image of the traffic imitation service. The colored boxes represent cars. Click image for complete version.Courtesy of Jiang ChangJun.What is the fastest way to drive from here to there? Will you find parking upon arrival? The Traffic Information Grid is a project aiming to provide more accurate travel predictions via grid technology. The project, centered at Tongji University in Shanghai, China, acquires data from cameras and GPS devices on taxis and buses. TIG seeks to weave real-time and historical traffic data into services accessible on a Web site, PDA or mobile phone. Some of these services include real-time route calculation, long-term forecast of future traffic conditions of a given route, optimization of travel plans—given current and predicted conditions—and dynamic information of available parking.To learn more about the Traffic Information Grid click here.

Image of the Week: The First Sources of LightCourtesy of Texas Advanced Computing Center.Understanding the nature of the first stars and galaxies, which formed a few hundred million years after the Big Bang, is at the frontier of modern cosmology. They lie just above the horizon of what is currently observable. NASA is preparing to launch the James Webb Space Telescope to replace the Hubble. This new telescope will be able to observe these early stars and galaxies. In preparing for this key upcoming mission it is important to predict the properties of the first sources of light. Volker Bromm’s astronomy research group at The University of Texas at Austin simulates these first stars using TeraGrid computers at the Texas Advanced Computing Center. This picture, produced by Paul Navratil of the Visualization and Data Analysis group at TACC using additional TeraGrid resources, shows how one of the first stars creates a bubble of high-energy, ionizing photons, thereby beginning the process of transforming the primordial universe in

Image of the Week: Down the Rabbit Hole Seven elements of the High Momentum Particle Identification Detector are set up on a platform before insertion inside ALICE’s octogonal magnet structure. Image courtesy of CERN ALICE, A Large Ion Collider Experiment, is one of five experiments preparing to receive data from the Large Hadron Collider at CERN starting in 2008. ALICE is a nuclear physics experiment built to study the nature of the quark-gluon plasma. Scientists consider the quark-gluon plasma to be a fundamental key to understanding both the basic structure of ordinary matter and the birth of matter in the early universe. The ALICE collaboration involves more than 1,000 physicists, engineers and technicians from 30 countries, and will use the services and collaborating grid infrastructures of the Worldwide LHC Computing Grid to provide experimental data to its members.

Image of the Week: Spallation Neutron Source The Spallation Neutron Source accumulator ring. (Courtesy of Oak Ridge National Laboratory managed for the U.S. Dept. of Energy by UT-Battelle, LLC) Neutron scattering is used by many scientific disciplines to determine the structure and dynamics of matter. The $1.4 billion Spallation Neutron Source was completed at Oak Ridge National Laboratory in May of this year. When it reaches full power, the SNS will provide the most intense pulsed neutron beams in the world for scientific research and industrial development using neutron scattering. With more intense beams and new experimental technologies comes an explosion of neutron scattering data. With the first experiments set to be carried out at the SNS by the end of 2006, researchers are developing a Neutron Science Instrument Gateway to the TeraGrid. This gateway will include tools for analysis, visualization, and instrument simulation, as well as data hosting,
