Scientists are taking baby steps toward imitating what cells do all the time.
The best way to appreciate the metaphor of a cell as a city or factory is to turn on the lights.
On most days, city services are invisible to residents. We take them for granted through a lack of thoughtfulness — and gratitude.
Kinesins and other “walking” motors in the cell are dazzling scientists.
Tiny organisms manufacture rocket fuel in a reaction machine that contributes to global planetary habitability. No kidding.
