Helping bacteria be better friends

Bacteria, like people, have complicated relationships. A group of researchers was able to engineer the genomes of 4 species of gut bacteria to make them rely on each other for essential nutrients rather than competing for them, and the whole community was stronger and more balanced as a result. This technology could enable bacteria-based therapies and tools that could be used to improve human health, produce valuable substances, or repair microbial ecosystems.
