Caltech biologist Elliot Meyerowitz and colleagues have found that the unusual shape of pavement cells, found on the leaves of flowering plants, represents a state of balance—an individual cell's tug-of-war to maintain structural integrity while also dynamically responding to the pushes and pulls of mechanical stress.

On Wednesday, April 2, Professor of Biology Sarkis Mazmanian will introduce you to the array of bacteria—your microbiome—residing on your skin, in your mouth, and even deep in your guts. Millions of years of coevolution have inextricably linked you and your microbiome, whose chemical "factories" help keep you healthy by doing such things as synthesizing vitamins and digesting your food. Recently, Mazmanian's laboratory has uncovered the surprising roles they play in fending off certain diseases. The talk begins at 8:00 p.m. in Caltech's Beckman Auditorium. Admission is free.

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

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.

Using a novel microfluidic technique, researchers at Caltech have shown that blood stem cells might be more actively involved in battles against infection. Rather than simply replenishing immune cells after they become depleted, new research shows that blood stem cells sense danger signals directly and quickly produce new immune cells.

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.
