Caltech Laboratories Shine Light on the Surprising, Ancient Behavior of Jellyfish

The Cassiopea jellyfish spends most of its life resting upside down on underwater surfaces. Credit: Caltech At first glance, humans seem to have very little in common with Cassiopea, a primitive jellyfish. Cassiopea is brainless, spineless, and spends essentially its entire life sitting upside down on the ocean floor, pulsating every few seconds. However, Caltech scientists have now discovered that, as different as our daily…

No, the Mexico Earthquakes Won’t Trigger Earthquakes in Pasadena

As a spate of major and minor earthquakes have recently wreaked havoc upon Mexico and throughout the Pacific “Ring of Fire,” the popular theory is that this has now increased the chances that Southern California…

JPL-Produced Damage Maps May Aid Mexico Quake Response

For the 1981-82 school year, three giants on Caltech’s faculty—Richard Feynman, Carver Mead (BS ’56, MS ’57, PhD ’60), and John Hopfield—joined up to co-teach a yearlong course called “The Physics of Computation.” The course was intended to unite their respective fields of study—physics, engineering, and biology—to explore the relationship between nanoscale physics, computation, and brain function. Though the class was only taught for three years, it became the seed of a…
