Getting Better with a Little Help from Our "Micro" Friends

A naturally occurring molecule made by symbiotic gut bacteria may offer a new type of treatment for inflammatory bowel disease, according to scientists at the California Institute of Technology.

Illusions of the Present

Have you ever noticed that signposts and trees on the side of the road seem to whoosh by faster right as you drive past them, or that a door frame seems to curve outward as you approach it? These are just two examples of real-life movements that underlie more than 50 types of illusions, now systematically organized and explained by scientists at the California Institute of Technology.

Sight Recovery After Blindness Offers New Insights on Brain Reorganization

Studies of the brains of blind persons whose sight was partially restored later in life have produced a compelling example of the brain's ability to adapt to new circumstances and rewire and reconfigure itself.

Unraveling the Genomic Code for Development

Scientists at the California Institute of Technology have produced the first complete description of the complex network of genes that create a particular type of cell in an organism.

Two Faculty Members Join American Academy of Arts and Sciences

Caltech professors Michael Dickinson and Thomas Palfrey are among the 190 new fellows elected to the American Academy of Arts and Sciences this year. They join an assembly that was founded in 1780 by John Adams, James Bowdoin, John Hancock, and other scholars to provide practical solutions to pressing issues.

Decoupling through Synchrony

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.

Geneticist Giuseppe Attardi Dies

Giuseppe Attardi, whose work linked degenerative diseases and aging to genetic mutations, died at his home in Altadena on Saturday, April 5. He was 84 years old.

New Rosen Bioengineering Center Funded

Seeing a burgeoning new research field at the interface of biology and engineering, the Benjamin M. Rosen Family Foundation of New York has donated $18 million to the California Institute of Technology to establish the Donna and Benjamin M. Rosen Bioengineering Center.

Fly Flight Simulators Reveal Secrets of Decision Making

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.

Pupil Dilation Marks Decision Making

The eyes may be the windows to the soul, but the simple pupil--the circular opening at the center of the eye that contracts and dilates to regulate the amount of light the eye receives--offers a remarkable portal to the inner workings of the brain. Such is the conclusion of neurobiologist Christof Koch of the California Institute of Technology and his colleagues, who have found that changes in pupil diameter correspond to the moment when a simple decision is made.
