Scientists discover how a single cell builds a brain with 170 billion cells
How does a single cell build a brain with billions of precisely organized neurons? Researchers suggest that brain cells use their lineage-their cellular family tree-as a kind of positional map. Cells that come from the same ancestor stay near one another, helping the brain organize itself without relying solely on chemical signals.
The science section covers breakthroughs in medicine, physics, biology, and technology. We surface discoveries that expand what humanity can do, from new treatments reaching clinical trials to engineering feats that seemed impossible a decade ago.
