- The body has a daily clock inside.
- A small brain area controls that clock.
- Many tiny cells in the area work together.
- Scientists watched cell activity for many weeks.
- They built a new computer tool to study cells.
- The tool mapped connections between many cells.
- A few hub cells make others work together.
- If hub cells are removed, rhythms stop.
- This finding shows hub cells are critical.
- Researchers hope to help people with shift work.
