When people think about the building of the Egyptian pyramids, they probably have a mental image of thousands of slaves laboriously rolling massive stone blocks with logs and levers.

A team of scientists at the California Institute of Technology and the State University of New York at Stony Brook has found strong evidence that high-luminosity quasar activity in galaxy nuclei is linked to the presence of abundant interstellar gas and high rates of star formation.

PASADENA, Ca.— Proteins are the cell's arbiters. In a complex and still largely mysterious cascade of events, proteins tell a cell when to divide and grow—and when to die. To properly control cell behavior, proteins need to be turned on when they are needed, and turned off when they are not.

California Institute of Technology researchers have received a $100,000 grant from the Alice C. Tyler Perpetual Trust to study the human impact on land and water in the San Gabriel Valley and San Gabriel River watershed. Ecosystems bordering major metropolitan areas are subject to intense pressures from pollutants produced by transportation, industrial activities, power generation, and recreational activities. This project will measure and document these environmental changes in order to predict future impacts.

Gasoline averaging $3 per gallon? Oil drilling in an Alaskan wildlife reserve? A need to relax air quality standards? It seems the long-term future of fossil fuels is bleak. One promising solution scientists have been studying is fuel cells, but they've had limitations too. Now, in the April 19 issue of the science journal Nature, the California Institute of Technology's Sossina M. Haile reports on a new type of fuel cell that may resolve these problems.

Scientists have revived and modernized a nearly forgotten technique for monitoring Earth's climate by carefully observing "earthshine," the ghostly glow of the dark side of the moon.
