It sits opposite Ursa Major across the celestial pole

with its 86 billion neurons and unmistakable folded surface

Working neuroscientists buy them as a daily-wear reference to the cell type their work depends on

The closed loop is the older architecture, and it never went away. The Science Behind Circular DNA Bacteria carry their genome as a circular chromosome alongside smaller circular plasmids, autonomously replicating DNA
