Scientists have discovered a previously undocumented group of immune cells that interact with the nervous system to play a key role in obesity. They suggest that the breakthrough may lead to new targets for obesity treatments. The researchers – led by Ana Domingos, Ph.D., from the Instituto Gulbenkian de Ciência in Portugal – describe the new immune cells, which they call sympathetic neuron-associated macrophages (SAMs), in a new paper published in the journal Nature Medicine.

Your Brain on Autopilot
Ever realized you have driven yourself home but have not really been paying attention? Brain scans have revealed that when your mind wanders, it switches into “autopilot” mode, enabling you to carry on without much conscious thought. Our autopilot mode seems to be run by a set of brain structures called the default mode network (DMN). Several studies have found that the DMN seems to be involved in assessing past events and planning for the future. Others suggest the network is involved in self-awareness.
