A century of phage research: bacteriophages and the shaping of modern biology.

2015 marks the centennial of the discovery of bacteriophages, viruses that infect bacteria. Phages have been central to some of biology's most meaningful advances over the past hundred years (shown here); they greatly influence the workings of the biosphere, and are poised to play expanded roles in biomedicine, biotechnology, and ecology.
