Weak Electrical Fields in the Brain Help Neurons Fire Together

02-03-11

Costas Anastassiou, a postdoctoral scholar working with Professor Christof Koch, and colleagues have found that coordinated behavior occurs in the brain whether or not neurons are actually connected via synapses.  To tease out the effects, Anastassiou and his colleagues, focused on strong but slowly oscillating fields, called local field potentials (LFP), that arise from neural circuits composed of just a few rat brain cells.  Measuring those fields and their effects required positioning a cluster of tiny electrodes within a volume equivalent to that of a single cell body—and at distances of less than 50 millionths of a meter from one another.

New Reactor Paves the Way for Efficiently Producing Fuel from Sunlight

01-20-11

Sossina Haile, Professor of Materials Science and Chemical Engineering, and colleagues have built a reactor at the heart of which is a cylindrical lining of ceria—a metal oxide. The reactor takes advantage of ceria's ability to "exhale" oxygen from its crystalline framework at very high temperatures and then "inhale" oxygen back in at lower temperatures - concentrating solar energy in order to convert carbon dioxide and water into fuels .  Ultimately, Haile says, the process could be adopted in large-scale energy plants, allowing solar-derived power to be reliably available during the day and night. [Caltech Press Release]
