Using digital blueprints of the metabolism of microbes, scientists can simulate expensive and time-intensive experiments set in space, power plants and farm fields.

The world is full of microbes, and many of them like the taste of waste. Some carbon monoxide-loving microbes can be harnessed to transform waste into valuable biofuel.

Switchgrass takes a break during the summer. Solving the puzzle of why could help it realize its full potential as a low-cost biofuel crop.
