"Our study develops a mathematical model to describe the designs it adopts and why, which could help direct design of future photoelectric devices," says Johnson, who collaborated on his study with colleagues from the Universidad de los Andes in Colombia.

Researchers from the University of Birmingham have created a closed loop hydrogen energy eco-system based on two types of bacteria and a twist of fuel cell technology. How did they do that?
