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.
"Traditional research has studied autism as a genetic disorder and a disorder of the brain, but our work shows that gut bacteria may contribute to ASD-like symptoms in ways that were previously unappreciated," says Sarkis Mazmanian.
"Our group is interested in the chemical transformations that are relevant to feeding and fueling the planet. There are two efforts on this campus in artificial photosynthesis, and I participate in both."
Today Caltech announced the appointment of Thomas F. Rosenbaum as the Institute's ninth president. Dr. Rosenbaum is currently the John T. Wilson Distinguished Service Professor of Physics and provost at the University of Chicago.
The industrial technique used to make nitrogen fertilizers mirrors the natural process of nitrogen fixation but requires high heat and pressure. Researchers at Caltech have synthesized a catalyst that allows for nitrogen fixation under much milder conditions.
