The teams that took the field at the Rose Bowl last Friday afternoon were composed of none other than Caltech's own Fleming House denizens, past and present. Continuing a tradition started in 2001, the students took the afternoon off to socialize with their fellow Flems, get to know some alumni, and play a few games of touch football in Myron Hunt's famous stadium.

A team of astronomers has found that the most active galactic nuclei—enormous black holes that are violently devouring gas and dust at the centers of galaxies—may prevent new stars from forming. The team, which includes several researchers from Caltech, reported its findings in the May 10 issue of the journalĀ Nature.

For those who study earthquakes, one major challenge has been trying to understand all the physics of a fault—both during an earthquake and at times of "rest"—in order to know more about how a particular region may behave in the future. Now, researchers at Caltech have developed theĀ first computer model of an earthquake-producing fault segment that reproduces, in a single physical framework, the available observations of both the fault's seismic (fast) and aseismic (slow) behavior.
