Roseanna Zia and Anthony Roy are Winners in the Graduate Student Poster Session

02-17-09

Mechanical Engineering graduate student Roseanna Zia has won the overall best poster prize in the first campus-wide Graduate Student Poster Session sponsored by the Graduate Student Council (GSC). Her poster was titled "Single particle motion in colloids: force-induced diffusion." The other winner, Anthony Roy, also a graduate student in Mechanical Engineering, won in the interdisciplinary category with his poster titled "Genetic programming of an artificial neural network for robust control of a 2-D path following robot." Congratulations!

Carver Mead and Gordon Moore Among the 2009 Inductees into the National Inventor's Hall of Fame

02-13-09

Carver Mead, Gordon and Betty Moore Professor of Engineering and Applied Science, Emeritus, and Caltech alumnus Gordon Moore, are among the fifteen 2009 inductees into the National Inventor's Hall of Fame. Mead helped to develop the standards and tools that permitted tens of thousands of transistors to be packaged on a single silicon chip, what is known as very large-scale integration (VLSI). Gordon Moore credits Mead with coining the term "Moore's Law" to describe the notion that the number of transistors that can be packaged on an integrated circuit will double every two years, and Mead performed the physics calculations to prove it. As a cofounder of both Fairchild Semiconductor and Intel, Moore set the pace and standards for Silicon Valley's chip manufacturing methods. His work established the model of the computer industry researcher-entrepreneur and help make Intel a world-leading chip maker.

Professor Ares Rosakis Featured in a Documentary

02-07-09

Ares Rosakis, Theodore von Karman Professor of Aeronautics and Professor of Mechanical Engineering, and Hiroo Kanamori, John E. and Hazel S. Smits Professor of Geophysics, Emeritus, with their students and colleagues will be featured in the documentary How the Earth Was Made airing on the History Channel on February 10, 6pm (PST) or 9:00pm (EST). The segment concerns the San Andreas fault and features a part which was filmed in the Solid Dynamics Lab at GALCIT. It also features an interview on supershear earthquake ruptures with Rosakis and Kanamori.

Douglas Hofmann and Colleagues Create Titanium-Based Structural Metallic-Glass Composites

12-19-08

Visiting scientist Douglas Hofmann (MS '06) and and colleagues, including William Johnson, Ruben F. and Donna Mettler Professor of Engineering and Applied Science, have created structural metallic-glass composites, based in titanium, that are lighter and less expensive than any the group had previously created, while still maintaining their toughness and ductility--the ability to be deformed without breaking. They are among the toughest engineering materials that currently exist. [Caltech Press Release]

Morteza Gharib and Abbas Nasiraei Moghaddam Show Function of Helical Band in Heart

12-01-08

Using an MRI technique, Morteza Gharib, Hans W. Liepmann Professor of Aeronautics and Professor of Bioengineering, and his colleague Abbas Nasiraei Moghaddam, a Caltech graduate and visitor in Bioengineering, were able to create some of the first dynamic images of normal heart muscle in action at the tissue level. They showed that a muscular band--which wraps around the inner chambers of the heart in a helix--is actually a sort of twisting highway along which each contraction of the heart travels. "We tagged and traced small tissue elements in the heart, and looked at them in space, so we could see how they moved when the heart contracts," Gharib explains. "In this way, we were able to see where the maximum physical contraction occurs in the heart and when--and to show that it follows this intriguing helical loop." [Caltech Press Release]

Michael Elowitz, Long Cai, and Chiraj Dalal Find Cells Coordinate Gene Activity with FM Bursts

10-17-08

How a cell achieves the coordinated control of a number of genes at the same time, a process that's necessary for it to regulate its own behavior and development, has long puzzled scientists. Michael Elowitz, assistant professor of biology and applied physics, along with postdoctoral research scholar Long Cai, and graduate student Chiraj Dalal, have discovered a surprising answer. Just as human engineers control devices ranging from dimmer switches to retrorockets using pulsed--or frequency modulated (FM)--signals, cells tune the expression of groups of genes using discrete bursts of activation.

John Dabiri Named One of "Brilliant Ten" by Popular Science Magazine

10-15-08

John Dabiri, assistant professor of aeronautics and bioengineering, has been named one of "Brilliant Ten" by Popular Science Magazine. Dabiri is the youngest scientist on the list at just 28 years of age. Dubbed "the jellyfish engineer" by the magazine, he garnered the award for his studies of the intricacies of jellyfish locomotion. Using a custom-built, high-definition video camera and a water-particle-illuminating laser, Dabiri and his colleagues are able to examine the fluid dynamics that determine how jellyfish propel themselves through their watery environment. Their hope is that those insights will be used to improve the designs of nonbiological systems as diverse as military submarines and onshore windmills. [Popular Science Article]

Paul Bellan Gives Explanation for a Strange Property of Night-shining Clouds

09-29-08

An explanation for a strange property of night-shining clouds has been proposed by Paul Bellan, Professor of Applied Physics. Noctilucent clouds - thin, wispy electric blue clouds clouds hovering at 85 km altitude - are highly reflective to radar. Ice grains in noctilucent clouds are coated with a thin film of metal, made of sodium and iron. The metal film causes radar waves to reflect off ripples in the cloud in a manner analogous to how x-rays reflect from a crystal lattice. [Caltech Press Release]
