## Internet Speed Quadrupled by International Team During 2004 Bandwidth Challenge

For the second consecutive year, the "High Energy Physics" team of physicists, computer scientists, and network engineers have won the Supercomputing Bandwidth Challenge with a sustained data transfer of 101 gigabits per second (Gbps) between Pittsburgh and Los Angeles. This is more than four times faster than last year's record of 23.2 gigabits per second, which was set by the same team.

## New Home for Astronomers

For almost 100 years, Caltech has been at the forefront of astronomy and astrophysics, pioneering research that has led to greater understanding of the earth, the solar system, and the Universe. Now the Institute is about to help its world-renowned astronomers and other investigators continue their groundbreaking discoveries well into the 21st century.

The Gordon and Betty Moore Foundation has awarded a $25.4 million grant to the California Institute of Technology to establish the Nanoscale Systems Initiative (NSI). The grant will support one of the scientific and technological community's promising research avenues--the creation of extremely tiny devices to augment and in some cases displace the state-of-the-art electronic systems of today. Laser Points to the Future at Palomar 11/04/2004 ## Laser Points to the Future at Palomar Jill Perry The Hale Telescope on Palomar Mountain has been gathering light from the depths of the universe for 55 years. It finally sent some back early last week as a team of astronomers from the California Institute of Technology, the Jet Propulsion Laboratory and the University of Chicago created an artificial star by propagating a 4-watt laser beam out from the Hale Telescope and up into the night sky. Observing the Roiling Earth 10/27/2004 ## Observing the Roiling Earth Marcus Woo Thanks to a$13,254,000 grant from the Gordon and Betty Moore Foundation, Caltech has established the Tectonic Observatory, under the direction of Avouac, with the ultimate goal, he says, of "providing a new view of how and why the earth's crust is deforming over timescales ranging from a few tens of seconds, the typical duration of an earthquake, to several tens of million of years."

## CBI Reveals Motion in the Remotest Seeds of Galaxy Clusters in the Very Early Universe

Robert Tindol
Cosmologists from the California Institute of Technology have used observations probing back to the remote epoch of the universe when atoms were first forming to detect movements among the seeds that gave rise to clusters of galaxies. The new results show the motion of primordial matter on its way to forming galaxy clusters and superclusters. The observations were obtained with an instrument high in the Chilean Andes known as the Cosmic Background Imager (CBI), and they provide new confidence in the accuracy of the standard model of the early universe in which rapid inflation occurred a brief instant after the Big Bang.

## David Politzer Wins Nobel Prize in Physics

Hugh David Politzer has won the 2004 Nobel Prize in physics for work he began as a graduate student on how the elementary particles known as quarks are bound together to form the protons and neutrons of atomic nuclei. The announcement was made today by the Royal Swedish Academy of Sciences.

## International Team of Scientists Establishes New Internet Land-Speed Benchmark

Robert Tindol
Scientists at the California Institute of Technology (Caltech) and the European Organization for Nuclear Research (CERN), along with colleagues at AMD, Cisco, Microsoft Research, Newisys, and S2io have set a new Internet2 land-speed record. The team transferred 859 gigabytes of data in less than 17 minutes at a rate of 6.63 gigabits per second between the CERN facility in Geneva, Switzerland, and Caltech in Pasadena, California, a distance of more than 15,766 kilometers. The speed is equivalent to transferring a full-length DVD movie in just four seconds.

## Caltech Physicists Achieve Measurement on a Single Magnetic Domain Wall

Physicists for several years have been predicting a new age of semiconductor devices that operate by subtle changes in the orientation of electron spins. Known as "spintronics," the field relies on an intricate knowledge of the magnetic properties of materials and of how magnetic moments can be manipulated.
