Schooling Fish Offer New Ideas for Wind Farming

The quest to derive energy from wind may soon be getting some help from California Institute of Technology (Caltech) fluid-dynamics expert John Dabiri-and a school of fish.

Caltech-Led Team Designs Novel Negative-Index Metamaterial that Responds to Visible Light

A group of scientists led by researchers from Caltech has engineered a type of artificial optical material—a metamaterial—with a particular three-dimensional structure such that light exhibits a negative index of refraction upon entering the material. In other words, this material bends light in the "wrong" direction from what normally would be expected, irrespective of the angle of the approaching light.

Solar Decathlon

Students from Caltech and the Southern California Institute of Architecture (SCI-Arc) have been chosen to build a green house near the White House. They will compete against teams from around the world in the biennial Solar Decathlon, sponsored by the U.S. Department of Energy.

Caltech Researchers Create Highly Absorbing, Flexible Solar Cells with Silicon Wire Arrays

Using arrays of long, thin silicon wires embedded in a polymer substrate, a team of scientists from the California Institute of Technology (Caltech) has created a new type of flexible solar cell that enhances the absorption of sunlight and efficiently converts its photons into electrons. The solar cell does all this using only a fraction of the expensive semiconductor materials required by conventional solar cells. 

Caltech Opens "Green" Building Offering New Opportunities in Information Science

New ideas in architecture will foster new ideas in information science as the California Institute of Technology (Caltech) opens its groundbreaking "green" building, the Walter and Leonore Annenberg Center for Information Science and Technology.

Caltech Researchers Show How Organic Carbon Compounds Emitted by Trees Affect Air Quality

A previously unrecognized player in the process by which gases produced by trees and other plants become aerosols—microscopically small particles in the atmosphere—has been discovered by a research team led by scientists at the California Institute of Technology (Caltech). Their research on the creation and effects of these chemicals, called epoxides, is being featured in this week's issue of the journal Science.

 

Caltech Researchers Link Tiny Sea Creatures to Large-scale Ocean Mixing

Using a combination of theoretical modeling, energy calculations, and field observations, researchers from the California Institute of Technology (Caltech) have for the first time described a mechanism that explains how some of the ocean's tiniest swimming animals can have a huge impact on large-scale ocean mixing.

Caltech Announces Initiative for a New $90 Million Sustainability Institute

California Institute of Technology (Caltech) president Jean-Lou Chameau began today's commencement ceremony by announcing $30 million in gifts as the first phase of a proposed $90 million initiative for a new institute. The funds will go towards the creation of the Resnick Sustainability Institute at Caltech.

Caltech Scientists Predict Greater Longevity for Planets with Life

Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into uninhabitability; the carbon dioxide in the atmosphere that serves as food for plant life will disappear, pulled out by the weathering of rocks; the oceans will evaporate; and all living things will disappear.

Or maybe quite so soon, say researchers from Caltech, who have come up with a mechanism that doubles the future lifespan of the biosphere.

DOE Names Caltech Professor as Director of EFRC Focusing on Light-Material Interactions

The U.S. Department of Energy (DOE) Office of Science has announced that it will fund the creation of 46 Energy Frontier Research Centers (EFRCs) over the next five years, including one that will be housed at the California Institute of Technology (Caltech). That EFRC will be headed by Harry Atwater, the Howard Hughes Professor and professor of applied physics and materials science.
