Research in genomic sciences, astronomy, seismology, and neuroeconomics are some of the many projects being funded at the California Institute of Technology (Caltech) by the American Recovery and Reinvestment Act (ARRA).

Saturn's largest moon, Titan, looks to be the only place in the solar system—aside from our home planet, Earth—with copious quantities of liquid (largely, liquid methane and ethane) sitting on its surface. According to Caltech planetary astronomer Mike Brown, Earth and Titan share yet another feature, which is inextricably linked with that surface liquid: common fog.

Researchers at Caltech suggest that the eccentricity of Saturn's orbit around the sun may be responsible for the unusually uneven distribution of lakes over the northern and southern polar regions of the planet's largest moon, Titan. A paper describing the theory appears in the November 29th advance online edition of Nature Geoscience.

Researchers at the California Institute of Technology (Caltech) have identified an unexpected metabolic ability within a symbiotic community of microorganisms that may help solve a lingering mystery about the world's nitrogen cycling budget. A paper about their work appears in the October 16 issue of the journal Science.

Saturn's moon Titan is dull, weatherwise. Nothing happens for years, making it hard to understand the carved channels that seem to line the surface. Now Titan has finally been caught in the act. Caltech planetary astronomer Mike Brown and his colleagues set a trap for Titan, waited years for it to be tripped, and, finally, nabbed their prey: bright but transient clouds over Titan's tropics, a region where clouds were thought unlikely to form.

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.

Stromatolites are dome- or column-like sedimentary rock structures that are formed in shallow water, layer by layer, over long periods of geologic time. Now, researchers from the California Institute of Technology (Caltech) and the Jet Propulsion Laboratory (JPL) have provided evidence that some of the most ancient stromatolites on our planet were built with the help of communities of equally ancient microorganisms.

An innovative sky survey has begun returning images that will be used to detect unprecedented numbers of powerful cosmic explosions–called supernovae–in distant galaxies, and variable brightness stars in our own Milky Way.

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.

Championing the modern-day use of solar eclipses to solve a set of modern problems is the goal of a review article written by Jay Pasachoff, visiting associate at the California Institute of Technology (Caltech) and Field Memorial Professor of Astronomy at Williams College. The review is the cover story of the June 11 issue of Nature, as part of its coverage of the International Year of Astronomy.
