Christof Koch and Pietro Perona Found that Human Decisions are Influenced by Both Value and Saliency

04-02-10

Christof Koch, Lois and Victor Troendle Professor of Cognitive and Behavioral Biology and Professor of Computation and Neural Systems, Pietro Perona, Allen E. Puckett Professor of Electrical Engineering, and colleagues' research on decision making and visual saliency has found that human decisions are influenced by both value and saliency in a way that is consistent with the ideal Bayesian observer.

Beverely McKeon Shares Her Perspectives on Controlling Turbulence in Science Magazine

03-26-10

Beverley McKeon, Assistant Professor of Aeronautics, shares her perspectives on controlling turbulence in the March 2010 issue of Science. Professor McKeon states, "more than 100 years after Osborne Reynolds's seminal experiments on the transition of flow through a pipe from a laminar to a turbulent state, the exact physical mechanism that drives this phenomenon still vexes the fluid mechanics community."

First Brain Recordings from Behaving Fruit Flies

02-16-10

Michael Dickinson, the Esther M. and Abe M. Zarem Professor of Bioengineering, with postdoctoral scholars Gaby Maimon and Andrew Straw have obtained the first recordings of brain-cell activity in an actively flying fruit fly. The work suggests that at least part of the brain of the fruit fly "is in a different and more sensitive state during flight than when the fly is quiescent," Dickinson says. [Caltech Press Release]

Nanoscale Structures with Superior Mechanical Properties

02-09-10

Julia Greer, Assistant Professor of Materials Science and Mechanical Engineering, and Dongchan Jang, Postdoctoral Scholar, have developed a way to make some notoriously brittle materials ductile—yet stronger than ever—simply by reducing their size. Professor Greer describes, "We are entering a new era in materials science, where structural materials can be created not only by utilizing monolith structures, like ceramics and metals, but also by introducing 'architectural' features into them."

Oskar Painter and Colleagues Propose Quantum Entanglement for Motion of Microscopic Objects

12-21-09

Oskar Painter, Associate Professor of Applied Physics, along with colleagues Darrick Change, Postdoctoral Scholar at Institute for Quantum Information, and H. Jeff Kimble, William L. Valentine Professor and Professor of Physics have proposed a new paradigm that should allow scientists to observe quantum behavior in small mechanical systems. Their idea offers a new means of studying the nature of quantum superposition and entanglement in progressively larger and more complex systems. [Caltech Press Release]

DNA Origami Nanoscale Breadboards for Carbon Nanotube Circuits

11-10-09

Hareem T. Maune, a graduate student studying carbon nanotube physics, and Si-ping Han, a graduate student investigating the interactions between carbon nanotubes and DNA have developed DNA origami nanoscale breadboards for carbon nanotube circuits. "This collaborative research project is evidence of how we at Caltech select the top students in science and engineering and place them in an environment where their creativity and imagination can thrive," says Ares Rosakis, chair of the Division of Engineering and Applied Science at Caltech and Theodore von Kármán Professor of Aeronautics and Professor of Mechanical Engineering. The work of these students was supervised by: Erik Winfree, Associate Professor of Computer Science, Computation and Neural Systems, and Bioengineering; William A. Goddard III, Charles and Mary Ferkel Professor of Chemistry, Materials Science, and Applied Physics; Paul W.K. Rothemund, Senior Research Associate, and Marc Bockrath, Associate Professor of Physics at University of California Riverside. [Caltech Press Release]
