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.

Methane, a key greenhouse gas, has more than doubled in volume in Earth's atmosphere since 1750. Its increase is believed to be a leading contributor to climate change. But where is the methane coming from? Research by atmospheric chemist Paul Wennberg of the California Institute of Technology (Caltech) suggests that losses of natural gas—our "cleanest" fossil fuel—into the atmosphere may be a larger source than previously recognized.

Caltech researchers have, for the first time, pinpointed areas of the brain that seem to serve as “arbitrators” between two decision-making systems, weighing the reliability of the predictions each makes and then allocating control accordingly.

In Caltech's Earth Surface Dynamics Lab the behavior of rivers is modeled through the use of artificial rivers through which water can be pumped at varying rates over a variety of sediments.

By incorporating the data of individual stars into whole-galaxy models, Caltech researchers can look at the actual effects of star feedback—how radiation from stars "pushes" on galactic matter—in the galaxies they study.
