Phys.org / Phage viruses, used to treat antibiotic resistance, gain advantage by cutting off competitors' reproduction ability

Curious bits of DNA tucked inside genomes across all kingdoms of life historically have been disregarded since they don't seem to have a role to play in the competition for survival, or so researchers thought.
