Two scientists from Caltech have been recognized by the National Institutes of Health for their innovative and high-impact biomedical research programs. Michael Roukes, professor of physics, applied physics, and bioengineering, and co-director of the Kavli Nanoscience Institute, and Pamela Bjorkman, Caltech's Max Delbrück Professor of Biology and a Howard Hughes Medical Institute investigator, now join the 81 Pioneers who have been selected since the program's inception in 2004.

The quest to derive energy from wind may soon be getting some help from California Institute of Technology (Caltech) fluid-dynamics expert John Dabiri-and a school of fish.

A team of scientists from Columbia University, Arizona State University, the University of Michigan, and Caltech have programmed an autonomous molecular "robot" made out of DNA to start, move, turn, and stop while following a DNA track.
The development could ultimately lead to molecular systems that might one day be used for medical therapeutic devices and molecular-scale reconfigurable robots—robots made of many simple units that can reposition or even rebuild themselves to accomplish different tasks.

We are not alone—even in our own bodies. The human gut is home to 100 trillion bacteria, which have co-evolved along with our digestive and immune systems. Most people view bacteria as harmful pathogens causing infections and disease. But some microbes, taking a different evolutionary path, have established beneficial relationships with their hosts. Still others may be perched somewhere in between, according to research by Caltech biologists that offers new insight into the causes of inflammatory bowel disease and colon cancer.

A group of scientists led by researchers from Caltech has engineered a type of artificial optical material—a metamaterial—with a particular three-dimensional structure such that light exhibits a negative index of refraction upon entering the material. In other words, this material bends light in the "wrong" direction from what normally would be expected, irrespective of the angle of the approaching light.

Taking inspiration from a popular executive toy ("Newton's cradle"), researchers at Caltech have built a device—called a nonlinear acoustic lens—that produces highly focused, high-amplitude acoustic signals dubbed "sound bullets." The acoustic lens and its sound bullets (which can exist in fluids—like air and water—as well as in solids) have the potential to revolutionize applications from medical imaging and therapy to the nondestructive evaluation of materials and engineering systems.

Producing coherent light on a microchip is old hat—LED lasers underpin our high-tech world, appearing in gadgets ranging from DVD players and supermarket checkout scanners to digital data lines. A new chip-compatible component developed at Caltech can produce coherent sound as well, and even interconvert the two. Who knows where this marriage of sound and light might lead?

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.
