Caltech Researchers Find Ancient Climate Cycles Recorded in Mars Rocks

Researchers at the California Institute of Technology (Caltech) and their colleagues have found evidence of ancient climate change on Mars caused by regular variation in the planet's tilt, or obliquity. On Earth, similar "astronomical forcing" of climate drives ice-age cycles.

Caltech's Novel Approach to Sustainability: Harvesting Olives

Once considered a messy sidewalk annoyance on the California Institute of Technology (Caltech) campus, the fruit of the 130 olive trees lining the campus pathways is now being embraced for its contribution to Caltech's sustainability. The olives will be harvested and pressed into olive oil in Caltech's second annual Olive Harvest Festival on Friday, November 7.

Caltech Geobiologists Discover Unique "Magnetic Death Star" Fossil

An international team of scientists has discovered microscopic, magnetic fossils resembling spears and spindles, unlike anything previously seen, among sediment layers deposited during an ancient global-warming event along the Atlantic coastal plain of the United States.

Caltech Solar Project Receives City Rebate

The California Institute of Technology (Caltech) and EI solutions, a leader in solar solutions, announced that the City of Pasadena has granted a rebate to the city's largest-ever solar-energy facility as part of the Pasadena Water & Power Pasadena Solar Initiative (PSI) program.

Caltech Scientists Awarded $20 Million to "Power the Planet"

In the dreams of Harry Gray, Beckman Professor of Chemistry at the California Institute of Technology, the future energy needs of the world are met with solar-fuel power plants. Now, a $20 million award from the Chemical Bonding Center (CBC), a National Science Foundation (NSF) Division of Chemistry program, will help bring this dream one step closer to reality.

Caltech Scientists Offer New Explanation for Monsoon Development

Geoscientists at the California Institute of Technology have come up with a new explanation for the formation of monsoons, proposing an overhaul of a theory about the cause of the seasonal pattern of heavy winds and rainfall that essentially had held firm for more than 300 years.

Chemistry of Airborne Particulate—Lung Interactions Revealed

Exactly how airborne particulates harm our lungs still puzzles epidemiologists, physicians, environmental scientists, and policy makers. Now California Institute of Technology researchers have found that they act by impairing the lungs' natural defenses against ozone.

Partnerships of Deep-Sea Methane Scavengers Revealed

The sea floor off the coast of Eureka, California, is home to a diverse assemblage of microbes that scavenge methane from cold deep-sea vents. Researchers at the California Institute of Technology have developed a technique to directly capture these cells, lending insight into the diverse symbiotic partnerships that evolved among different species in an extreme environment.

Caltech to Have Largest Solar-Energy Facility in Pasadena

The City of Pasadena's largest-ever solar-energy facility will soon be installed on the California Institute of Technology campus. Construction begins this week and will conclude in August. The facility will be located on top of Caltech's Holliston parking structure.

Caltech Creates New Center to Study the Global Environment

To address the complex issue of global climate change from a wide range of disciplines, Ronald and Maxine Linde have established an $18 million endowment for the California Institute of Technology to create the Ronald and Maxine Linde Center for Global Environmental Science, uniting faculty from chemistry, engineering, geology, environmental science, and other fields.
