In last night's State of the Union Address, President Obama said, "We're issuing a challenge. We're telling America's scientists and engineers that if they assemble teams of the best minds in their fields, and focus on the hardest problems in clean energy, we'll fund the Apollo projects of our time. At the California Institute of Technology, they're developing a way to turn sunlight and water into fuel for our cars.

Using a common metal most famously found in self-cleaning ovens, Sossina Haile hopes to change our energy future. The metal is cerium oxide—or ceria—and it is the centerpiece of a promising new technology developed by Haile and her colleagues that concentrates solar energy and uses it to efficiently convert carbon dioxide and water into fuels.

A team of scientists led by researchers from Caltech and JPL have fully characterized a key chemical reaction that affects the formation of pollutants in smoggy air. The findings suggest that in the most polluted parts of Los Angeles—and on the most polluted days in those areas—current models are underestimating ozone levels, by between 5 to 10 percent.

An encounter with summer smog in Yosemite National Park led Caltech graduate student and accomplished nature photographer William Chueh to take action through science. His resulting research could help reduce the planet's dependence on fossil fuels, not to mention clean the air over Yosemite.

As part of a broad effort to achieve breakthrough innovations in energy production, U.S. Deputy Secretary of Energy Daniel Poneman announced an award of up to $122 million over five years to a multidisciplinary team of top scientists, led by Caltech, to establish an Energy Innovation Hub aimed at developing revolutionary methods to generate fuels directly from sunlight.

For the past month, Caltech scientists have been zigzagging across the Los Angeles basin. Using an orange and white DeHavilland Twin Otter aircraft packed with instruments, the researchers have been sampling the air, measuring particles and pollutants to help policymakers improve air quality and dampen the impacts of climate change.

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.

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.
