Synthetic microbiome? Genetic engineering allows different species of bacteria to communicate

What if the bacteria that live in your gut could monitor your health, report disease, and produce beneficial molecules? Researchers have gotten one step closer to creating such a 'synthetic microbiome' by engineering different species of bacteria so they can talk to each other. Given that there are over 1,000 different strains of intestinal interlopers in the human gut, such coordination is crucial for the development of systems that can sense and improve human digestive health.
