Your physical environment, social life and lifestyle have as much an influence on your biology − and hence, how you process drugs − as your genes.

Using digital blueprints of the metabolism of microbes, scientists can simulate expensive and time-intensive experiments set in space, power plants and farm fields.

Your gut microbes have a lot to say about how many calories you consume and how effectively your body metabolizes them.

Targeting the key players that help your body regulate metabolism could reverse disease progression, including cognitive decline related to Alzheimer’s disease.

An elite athlete’s metabolism mostly looks different from a patient with COVID-19 − but their occasional similarities can reveal important insights into health and disease.

Weight loss and diabetes drugs target regulatory pathways involved in metabolism that the microbes in your gut and certain molecules from food already play a key role in regulating.
