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.

Manhattan Project Physicist Robert Bacher Dies

Robert Fox Bacher, a renowned California Institute of Technology physicist who headed the experimental physics division at Los Alamos Laboratory during the Manhattan Project, died Thursday, November 18, in Montecito, California. He was 99.

Laser Points to the Future at Palomar

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.

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

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.

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.

International Team of Scientists Establishes New Internet Land-Speed Benchmark

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.

Gamma-ray burst of December 3 was a new type of cosmic explosion

Astronomers have identified a new class of cosmic explosions that are more powerful than supernovae but considerably weaker than most gamma-ray bursts. The discovery strongly suggests a continuum between the two previously-known classes of explosions.

Physicists Successful in Trapping Ultracold Neutrons at Los Alamos National Laboratory

Free neutrons are usually pretty speedy customers, buzzing along at a significant fraction of the speed of light. But physicists have created a new process to slow neutrons down to about 15 miles per hour—the pace of a world-class mile runner—which could lead to breakthroughs in understanding the physical universe at its most fundamental level.
