Two and a half billion years ago, single-celled organisms called cyanobacteria harnessed sunlight to split water molecules, producing energy to power their cells and releasing oxygen into an atmosphere that had previously had none. These early environmental engineers are responsible for the life we see around us today, and much more besides. At 8:00 p.m. on Wednesday, November 19, in Caltech's Beckman Auditorium, Professor of Geobiology Woodward "Woody" Fischer will describe how they transformed the planet. Admission is free.

An ankle- or hip-deep stream once flowed with force across the surface of Mars in the very spot where the Curiosity rover is currently exploring. The finding provides new information about a once wet environment in Gale Crater.

Several hypotheses have been proposed to explan how clay minerals detected on the surface of Mars were formed. Now, publishing in the journal Nature Geoscience, a team of French and American scientists including Caltech's Bethany Ehlmann, has suggested a new possibility. The Los Angeles Times recently spoke to Ehlmann about the paper and its implications.

Ever since a crash landing on Earth grounded NASA's Genesis mission in 2004, scientists have been gathering, cleaning, and analyzing solar wind particles collected by the spacecraft. Now, two new studies published in Science reveal that Earth's chemistry is less like the sun's than previously thought.
