Exactly how airborne particulates harm our lungs still puzzles epidemiologists, physicians, environmental scientists, and policy makers. Now California Institute of Technology researchers have found that they act by impairing the lungs' natural defenses against ozone.

The sea floor off the coast of Eureka, California, is home to a diverse assemblage of microbes that scavenge methane from cold deep-sea vents. Researchers at the California Institute of Technology have developed a technique to directly capture these cells, lending insight into the diverse symbiotic partnerships that evolved among different species in an extreme environment.

In the biblical story in which two women bring a baby to King Solomon, both claiming to be the mother, he suggests dividing the child so that each woman can have half. Solomon's proposed solution, meant to reveal the real mother, also illustrates an issue central to economics and moral philosophy: how to distribute goods fairly.

Your brain gets a better workout when you change your routine, say scientists at the California Institute of Technology who have pinpointed one particular circuit that activates your ability to execute a decision. This finding may help drive research in neural prosthetics and in how unhealthy decisions are made.

In the brain, as in sports, sex, and life, timing--and teamwork--are everything. Such is the message of a series of studies by researchers at the California Institute of Technology that offer insight into the processes by which memories are stored in the brain and that may someday guide the development of new therapies to prevent epileptic seizures.

How the Grand Canyon was carved has been a topic of scientific controversy for nearly 140 years. Now, with new geochronologic data from the canyon and surrounding plateaus, geologists from the California Institute of Technology present significant evidence that the canyon formed nearly 50 million years earlier than previously thought.

Even flies like video games--and it's not just child's play, say scientists at the California Institute of Technology. With the help of a unique bug-sized flight simulator, Caltech researchers are deciphering the secrets of behavior and decision making in the fly brain, and, ultimately, in our own.

Water is an essential ingredient for forming planets, yet has remained hidden from scientists searching for it in protoplanetary systems, the spinning disks of particles surrounding newly formed stars where planets are born. Now the detection of water vapor in the inner part of two extrasolar protoplanetary disks brings scientists one step closer to understanding water's role during terrestrial planet formation.
