Great balls of fire: newborn nerve cells navigate their Universe. Some microscope images could have come from a powerful telescope. This neurosphere was cultured from an adult mouse brain in a project aiming to determine how new brain cells are born in the adult brain.
With nascent neurons (yellow) navigating amongst associated astrocytes (red), it reminds me of a meteorite in the night sky and highlights the mirror relationship between microcosm and macrocosm. In the century old words of Cajal, "As long as our brain is a mystery, the Universe, the reflection of the structure of the brain will also be a mystery."
