An Equation to Describe the Competition Between Genes

Kimm Fesenmaier
"The thing that makes this study really interesting is that we did our calculations before we ever did any experiments," says Rob Phillips, Caltech's Fred and Nancy Morris Professor of Biophysics and Biology.

Battling Infection With Microbes

Jessica Stoller-Conrad
In the recent study the researchers found that beneficial gut bacteria were necessary for the development of innate immune cells—specialized types of white blood cells that serve as the body's first line of defense against invading pathogens.

A Changing View of Bone Marrow Cells

Kimm Fesenmaier
Using a novel microfluidic technique, researchers at Caltech have shown that, rather than simply replenishing immune cells after they become depleted, blood stem cells sense danger signals directly and quickly produce new immune cells.

Caltech's "Secrets" to Success

Allison Benter
Everyone who really knows Caltech understands that it is unique among universities around the world. But just what makes Caltech so special? We've asked that question before, and the numbers don't tell the full story. So, is it our focus? Our culture? Our people?

Caltech-Developed Method for Delivering HIV-Fighting Antibodies Proven Even More Promising

Kimm Fesenmaier
"The method that we developed has now been validated in the most natural possible setting in a mouse," says David Baltimore, president emeritus and the Robert Andrews Millikan Professor of Biology at Caltech.

A Detailed Look at HIV in Action

Katie Neith
Researchers at Caltech are the first to have utilized high-resolution electron microscopy to look at HIV infection within the actual tissue of an infected organism, providing perhaps the most detailed characterization yet of HIV infection in the gut.

Fighting Flies

Katie Neith
According to the latest studies from the fly laboratory of Caltech biologist David Anderson, male fruit flies fight more than their female counterparts because they have special cells in their brains that promote fighting. These cells appear to be absent in the brains of female fruit flies.

Bacterial "Syringe" Necessary for Marine Animal Development

Jessica Stoller-Conrad
"It was a tremendous surprise that the agent that drives metamorphosis is such an elaborate, well-organized injection machine," says coauthor Grant Jensen.
