Caltech Receives More than $33 Million from American Recovery and Reinvestment Act

Research in genomic sciences, astronomy, seismology, and neuroeconomics are some of the many projects being funded at the California Institute of Technology (Caltech) by the American Recovery and Reinvestment Act (ARRA).

Caltech Researchers Create Highly Absorbing, Flexible Solar Cells with Silicon Wire Arrays

Using arrays of long, thin silicon wires embedded in a polymer substrate, a team of scientists from the California Institute of Technology (Caltech) has created a new type of flexible solar cell that enhances the absorption of sunlight and efficiently converts its photons into electrons. The solar cell does all this using only a fraction of the expensive semiconductor materials required by conventional solar cells. 

Watson Lecture: Creating Laboratory Earthquakes

Scientists at the California Institute of Technology (Caltech) have demonstrated that high-speed intersonic ruptures exist and could occur during the next major earthquake. The researchers now have the ability to create laboratory earthquakes of varying force and magnitudes that mimic actual quakes.  By triggering laboratory earthquakes, researchers can study the behavior of quakes and their potential force and destructiveness—without a real quake actually occurring.

Caltech Researchers Develop Nanoscale Structures with Superior Mechanical Properties

Caltech researchers have developed a way to make some notoriously brittle materials ductile—yet stronger than ever—simply by reducing their size. The work could eventually lead to innovative, superstrong, yet light and damage-tolerant materials. These materials could be used as components in structural applications, such as in lightweight aerospace vehicles that last longer under extreme environmental conditions and in naval vessels that are resistant to corrosion and wear.

Caltech Physicists Propose Quantum Entanglement for Motion of Microscopic Objects

Researchers at the Caltech have proposed a new paradigm that should allow scientists to observe quantum behavior in small mechanical systems. Their ideas, described in the early online issue of the Proceedings of the National Academy of Sciences, offer a new means of addressing one of the most fascinating issues in quantum mechanics: the nature of quantum superposition and entanglement in progressively larger and more complex systems.

The Book of Bruck

How would Jehoshua “Shuki” Bruck sum up his success as a teacher in just three words? “I love ignorance,” declares the exuberant winner of Caltech’s 2008 Feynman Prize for Excellence in Teaching.

Caltech Scientists Find Emotion-like Behaviors, Regulated by Dopamine, in Fruit Flies

Scientists at the California Institute of Technology (Caltech) have uncovered evidence of a primitive emotion-like behavior in the fruit fly, Drosophila melanogaster. Their findings, which may be relevant to the relationship between the neurotransmitter dopamine and attention deficit hyperactivity disorder (ADHD), are described in the December issue of the journal Neuron.

Caltech and Dow Chemical Team Up in Solar Materials Effort

The California Institute of Technology (Caltech) and the Dow Chemical Company today announced a new solar-research collaboration aimed at developing the use of semiconductor materials that are less expensive and more abundant than those used in many of today's solar cells. In addition, they announced the creation of the Dow Chemical Company Graduate Fellowship in Chemical Sciences and Engineering.

Caltech Scientists Develop DNA Origami Nanoscale Breadboards for Carbon Nanotube Circuits

In work that someday may lead to the development of novel types of nanoscale electronic devices, an interdisciplinary team of researchers at the California Institute of Technology (Caltech) has combined DNA's talent for self-assembly with the remarkable electronic properties of carbon nanotubes, thereby suggesting a solution to the long-standing problem of organizing carbon nanotubes into nanoscale electronic circuits.

James. K. Knowles, 78

James K. Knowles, William J. Keenan Jr. Professor of Applied Mechanics, Emeritus, at the California Institute of Technology (Caltech), passed away November 1. He was 78 years old.
