Caltech Installs New High-Performance HP Exemplar System at Center for Advanced Computing Research

PASADENA—At a dedication ceremony to be held Monday, June 9, the California Institute of Technology will showcase the most powerful technical computing system developed by the Hewlett-Packard Company, a 256-CPU Exemplar technical server. The Exemplar system, which features peak performance of 184 gigaflops, 64 gigabytes of memory, and one terabyte of attached disk capacity, will serve as the premiere computing resource for Caltech's Center for Advanced Computing Research (CACR) and NASA's Jet Propulsion Laboratory.

Caltech Question of the Week: What Would Be the Effect If All Plate Tectonics Movement Stopped Forever?

Submitted by Jack Collins, Duarte, California, and answered by Kerry Sieh, Professor of Geology, Caltech.

Caltech Question of the Week: Why Does There Need To Be Water On a Planet or Moon To Have Life?

Question of the Month Submitted by Traci Salazar, 13, Alhambra, California, and answered by Richard Terrile, scientist, Jet Propulsion Laboratory, Caltech.

Water is a tremendously important ingredient in that it's a very good solvent and a very good medium for chemical reactions. It's also very common.

Water is nearly everywhere in the solar system, it's easy to make from two ingredients (hydrogen and oxygen) that are both very common throughout the solar system and the universe, and it can exist in some truly harsh environments.

Caltech Question of the Week: How Can Different Kinds of Vegetables Contain Different Vitamins When Grown in the Same Soil?

Question of the Month Submitted by Doris Bower, Arcadia, Calif., and answered by Dr. Elliot Meyerowitz, Professor of Biology, Caltech.

Caltech Astronomers Crack the Puzzle of Cosmic Gamma-Ray Bursts

A team of Caltech astronomers has pinpointed a gamma-ray burst several billion light-years away from the Milky Way. The team was following up on a discovery made by the Italian/Dutch satellite BeppoSAX.

Question of the Week: Does the earth keep a constant distance from the sun? If not, will the earth get closer to the sun and become more warm?

Caltech Astronomer Obtains Data That Could Resolve the "Age Problem"

Dr. Neill Reid, using information collected by the European Space Agency's Hipparcos satellite, has determined that a key distance measure used to compute the age of certain Milky Way stars is off by 10 to 15 percent. The new data leads to the conclusion that the oldest stars are actually 11 to 13 billion years old, rather than 16 to 18 billion years old, as had been thought.

Caltech A Major Partner in National Program To Develop Advanced Computational Infrastructure

PASADENA, California — The California Institute of Technology (Caltech) will play three key roles in the National Partnership for Advanced Computational Infrastructure (NPACI) in the areas of management, resource deployment, and technology and application initiatives. The NPACI program is one of two partnerships each awarded approximately $170 million over five years in the National Science Foundation's Partnerships for Advanced Computational Infrastructure (PACI) slated to begin October 1, 1997.

Question of the Week: Who Invented the Equal Sign, and Why?

Submitted by Pat Orr, Altadena, California, and answered by Tom Apostol, Professor of Mathematics Emeritus, Caltech.

Caltech Scientists Invent Polymer For Detecting Blood Glucose

PASADENA— Scientists have designed a polymer that could vastly improve the way diabetics measure their blood glucose levels. The polymer is described in the current issue of Nature Biotechnology.

According to Dr. Frances Arnold, a professor of chemical engineering at the California Institute of Technology, the polymer is superior to the current enzyme-based glucose detectors because it is not of biological origin. The polymer will be easier to make and thus lead to cheaper and more reliable glucose sensors.
