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 Ch

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).
