Around 520 million years ago, there was a period of rapid species diversification that many scholars describe as a sort of evolutionary "big bang." New modeling results from Caltech suggest that during this time period, the continents moved towards the equator instead of toward the poles.

A team led by Caltech's Jennifer Jackson, professor of mineral physics has new evidence for the origin of features that occur at the core-mantle boundary.

Caltech and JPL researchers identify a process involving UV light from the sun that helps explain how a moderately dense martian atmosphere 3.8 billion years ago could have evolved into the current thin one without invoking a missing carbon reservoir.

Using data from the W. M. Keck Observatory's OSIRIS spectrometer and maps from NASA's Galileo probe, researchers have mapped what may be salt deposits from the ocean below the ice onto the Jovian moon's surface.

The key to any healthy relationship is communication. Two types of microbes near the ocean floor use direct electron transfer to coordinate their symbiotic relationship—which results in the consumption of large amounts of methane from deep ocean vents.
