PHOENIX, Ariz.--Teams of physicists, computer scientists, and network engineers from Caltech, SLAC, LANL, CERN, Manchester, and Amsterdam joined forces at the Supercomputing 2003 (SC2003) Bandwidth Challenge and captured the Sustained Bandwidth Award for their demonstration of "Distributed particle physics analysis using ultra-high speed TCP on the Grid," with a record bandwidth mark of 23.2 gigabits per second (or 23.2 billion bits per second).

For the past several decades, astrophysicists have been puzzling over the origin of powerful but seemingly different explosions that light up the cosmos several times a day. A new study this week demonstrates that all three flavors of these cosmic explosions--gamma-ray bursts, X-ray flashes, and certain supernovae of type Ic--are in fact connected by their common explosive energy, suggesting that a single type of phenomenon, the explosion of a massive star, is the culprit. The main difference between them is the "escape route" used by the energy as it flees from the dying star and its newly born black hole.

PASADENA, Calif. – It might seem a bit of a stretch to see what the flight control of a 747 and the way a boxfish maneuvers in very turbulent water have in common. But such thinking is all in a day's work within the walls of the California Institute of Technology's Graduate Aeronautical Laboratories (GALCIT), which this week celebrates its 75th anniversary.

A new and improved way to measure light has been unveiled by physicists at the California Institute of Technology and the Jet Propulsion Laboratory. The technology exploits the strange but predictable characteristics of superconductivity, and has a number of properties that should lead to uses in a variety of fields, from medicine to astrophysics.

Astrophysicists have had an exceedingly difficult time charting the mysterious stuff called dark matter that permeates the universe because it's--well--dark. Now, a unique "mass map" of a cluster of galaxies shows in unprecedented detail how dark matter is distributed with respect to the shining galaxies.

Scientists at the California Institute of Technology (Caltech) and the European Organization for Nuclear Research (CERN) have set a new Internet2 land speed record using the next-generation Internet protocol IPv6. The team sustained a single stream TCP rate of 983 megabits per second for more than one hour between the CERN facility in Geneva and Chicago, a distance of more than 7,000 kilometers. This is equivalent to transferring a full CD in 5.6 seconds.
The performance is remarkable because it overcomes two important challenges:

For the first time, the planets orbiting a pulsar have been "weighed" by measuring precisely variations in the time it takes them to complete an orbit, according to a team of astronomers from the California Institute of Technology and Pennsylvania State University.
Reporting at the summer meeting of the American Astronomical Society, Caltech postdoctoral researcher Maciej Konacki and Penn State astronomy professor Alex Wolszczan announced today that masses of two of the three known planets orbiting a rapidly spinning pulsar 1,500 light-years away in the constellation Virgo have been successf

PASADENA, Calif. — The California Science Center has announced the joint selection of Andrew Lange and Saul Perlmutter as 2003 California Scientist of the Year.
Lange is Marvin L. Goldberger Professor of Physics at the California Institute of Technology in Pasadena, and Perlmutter is senior scientist and group leader at the Lawrence Berkeley National Laboratory in Berkeley. Using two very different techniques, Lange and Perlmutter's experimental efforts have confirmed a remarkable theory of how the universe expanded and evolved after the "big bang."
