New distance measurements from faraway galaxies further strengthen the view that the strongest burst of star formation in the universe occurred about two billion years after the Big Bang.
Reporting in the April 17 issue of the journal Nature, California Institute of Technology astronomers Scott Chapman and Andrew Blain, along with their United Kingdom colleagues Ian Smail and Rob Ivison, provide the redshifts of 10 extremely distant galaxies which strongly suggest that the most luminous galaxies ever detected were produced over a rather short period of time.

A basic discovery in magnetic semiconductors could result in a new generation of devices for sensors and memory applications -- and perhaps, ultimately, quantum computation -- physicists from the California Institute of Technology and the University of California at Santa Barbara have announced.
The new phenomenon, called the giant planar Hall effect, has to do with what happens when the spins of current-carrying electrons are manipulated.

Scientists "arriving quickly on the scene" of an October 4 gamma-ray burst have announced that their rapid accumulation of data has provided new insights about this exotic astrophysical phenomenon. The researchers have seen, for the first time, ongoing energizing of the burst afterglow for more than half an hour after the initial explosion.
The findings support the "collapsar" model, in which the core of a star 15 times more massive than the sun collapses into a black hole.

Caltech computer scientists have developed a new data transfer protocol for the Internet fast enough to download a full-length DVD movie in less than five seconds.
The protocol is called FAST, standing for Fast Active queue management Scalable Transmission Control Protocol (TCP). The researchers have achieved a speed of 8,609 megabits per second (Mbps) by using 10 simultaneous flows of data over routed paths, the largest aggregate throughput ever accomplished in such a configuration.

In the subatomic particle family, the neutrino is a bit like a wayward red-haired stepson. Neutrinos were long ago detected-and even longer ago predicted to exist-but everything physicists know about nuclear processes says there should be a certain number of neutrinos streaming from the sun, yet there are nowhere near enough.

Jesse L. Greenstein, an astrophysicist whose many accomplishments included seminal work on the nature of quasars, died Monday, October 21, 2002, three days after falling and breaking his hip. He was 93.
A native of New York City, Greenstein grew up in a family that actively encouraged his scientific interests. At the age of eight he received a brass telescope from his grandfather—not an unusual gift for an American child, but Greenstein soon was also experimenting in earnest with his own prism spectroscope, an arc, a rotary spark, a rectifier, and a radio transmitter.

Barry Barish, an experimental high-energy physicist at the California Institute of Technology, has been nominated to the National Science Board by President George W. Bush. The White House made the announcement Thursday, October 17.
Barish is the Linde Professor of Physics at Caltech, and since 1997 has been director of the Laser Interferometer Gravitational-Wave Observatory (LIGO) project, a National Science Foundation–funded collaboration between Caltech and MIT for detecting gravitational waves from exotic sources such as colliding black holes.
