AI CONCISE SUMMARY: Scientists have identified a novel type of brain cell that acts like both neurons and glial cells. Known as glutamatergic astrocytes, these cells release the primary neurotransmitter used by neurons (glutamate) and could lead to new treatments for Alzheimer's, Parkinson's, and other nervous system disorders. Further research is needed to explore their function in humans and potential protective role against memory impairment in Alzheimer's disease as well as their role in other regions and pathologies.

We live in amazing times for discovering how the body works. This and the discovery of an anti-vaccine to cure auto-immune disorders, all in the same week.
