Robotic Ocean Gliders Aid Study of Melting Polar Ice

Caltech researchers use robotic ocean gliders to study how warm water is making its way to Antarctic ice sheets—and how this warming ultimately leads to rising ocean levels.

Making Hotter Engines and Lasting Artwork: An Interview with Katherine Faber

New faculty member Katherine Faber, the Simon Ramo Professor of Materials Science, studies the reasons why brittle ceramics fracture—and how these materials can be made stronger in the future.

Unexpected Findings Change the Picture of Sulfur on the Early Earth

Using a new analytical technique, Caltech researchers studying the rock record uncover new information about the sulfur cycle on early Earth and what that could mean for the rise of oxygen in the atmosphere.

Caltech Rocket Experiment Finds Surprising Cosmic Light

Using an experiment carried into space on a NASA suborbital rocket, astronomers at Caltech and their colleagues have detected a diffuse cosmic glow that appears to represent more light than that produced by known galaxies in the universe.

Using Simulation and Optimization to Cut Wait Times for Voters

By developing a tool to help better prepare polling places, Caltech sophomore Sean McKenna is hoping to minimize the amount of time we spend in line at the polls.

No Galaxy Too Small: An Interview with Evan Kirby

"I study the smallest galaxies we know about...These galaxies are interesting because they are part of our cosmic story. The first galaxies to form were small ones, and over time they got smashed together to build up bigger ones."

Figuring Out How We Get the Nitrogen We Need

Caltech chemists have used the resources of the Molecular Observatory to take a crucial step toward unlocking the mystery of how bacteria use an enzyme called nitrogenase to convert nitrogen—an essential component of all living systems—into a form that living systems can use.

The Inauguration: New Leadership and Old Traditions

The inauguration of President Thomas F. Rosenbaum marks the beginning of a new era of leadership at Caltech. And yet, many of the traditional events associated with the inauguration ceremony itself are actually quite old.

Stoltz Wins Synthetic Chemistry Award

Professor of Chemistry Brian Stoltz has been named the winner of the 2015 Mukaiyama Award from the Society of Synthetic Organic Chemistry, Japan.

Caltech Awards International Aerospace Honor to Industry Leader

John Tracy, chief technology officer and senior vice president of engineering, operations, and technology for the Boeing Company, is the 2014 recipient of the International von Kármán Wings Award. The honor—bestowed annually by the Aerospace Historical Society, which is part of the Graduate Aerospace Laboratories of the California Institute of Technology (GALCIT)—acknowledges outstanding contributions by international innovators, leaders, and pioneers in aerospace.
