Last year, images from NASA's Mars Reconnaissance Orbiter captured sand dunes and ripples moving across the surface of Mars—observations that challenged previously held beliefs that there was not a lot of movement on the red planet's surface. Now, technology developed by a team at the California Institute of Technology (Caltech) has allowed scientists to measure these activities for the very first time.

By analyzing stalagmites, a team of Caltech researchers has determined that the climate signature in the tropics through four glacial cycles looks different in some ways and similar in others when compared to the climate signature at high latitudes. The results suggest that Earth's climate system might have two modes of responding to significant changes.

What's it like to build an entire research program from scratch? It's all about becoming part of a community, according to three brand-new professors who chat about their experiences in "From the Ground Up," an article in the Spring 2012 issue of Caltech's Engineering & Science magazine.

The second-largest mass extinction in Earth's history coincided with a short but intense ice age. Although it has long been agreed that the so-called Late Ordovician mass extinction was related to climate change, exactly how the change produced the extinction has not been known. Now, a team led by Caltech scientists has determined that the majority of extinctions were caused by habitat loss due to falling sea levels and cooling of the tropical oceans.

Many of us see a man in the moon—a human face smiling down at us from the lunar surface. The "face," of course, is just an illusion, shaped by the dark splotches of lunar maria (smooth plains formed from the lava of ancient volcanic eruptions). Like a loyal friend, the man is always there, constantly gazing at us as the moon revolves around Earth. But why did the moon settle into an orbit with the man facing Earth?

The field of study of Andrew Thompson, assistant professor of environmental science and engineering at Caltech, presents not only theoretical challenges but logistical ones as well. That's because he is interested in the circulation and ecology of the Southern Ocean and the role it plays in global climate. The hostile environment of this area makes long-term research difficult, so he's part of a team that is seeking to monitor the region with autonomous underwater vehicles called gliders.
