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.

A research team made up of scientists from Caltech and their partners in Peru and France report on their analysis of GPS data from the 2007 Pisco quake in Peru. They found, in part, that 50 percent of the postseismic slippage is aseismic—movement along a fault that occurs without any accompanying seismic waves.

It's been 15 years since members of the Caltech community last staged a musical, and five years since a student directed a Caltech production. Now sophomore Christina Kondos has taken on the plum job of directing I Love You, You're Perfect, Now Change, Off-Broadway's second-longest-running musical. The show, which explores the ups and downs of relationships from first date to last rites, opens May 7 in Ramo Auditorium on the Caltech campus.

"This Too Shall Pass," is the title of the song by the band OK Go, but the outpouring of interest that the accompanying music video has generated seems unlikely to pass anytime soon. And that is, to say the least, okay with a group of Caltechers who were involved in the design and construction of the video's centerpiece—a two-story-high Rube Goldberg machine that to date has been seen by more than 12 million viewers on YouTube.

On a visit to Caltech in March, astronaut and alumnus Garrett Reisman (PhD '97) talked at length about his upcoming mission on space shuttle Atlantis. On that two-week voyage, he'll be making two space walks and working at the Space Station, but he also hopes to fit in a bit of sightseeing and perhaps some Superman impersonations.

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.

R. David Middlebrook, emeritus professor of electrical engineering at the California Institute of Technology (Caltech), passed away on April 16. He was 80 years old.

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.
