Team analyzed 13 studies on human gut microbiome to develop ageing biomarker clock from it.
They trained a deep neural network using over 1000 microflora samples.
Resulting clock predicted the age of the person with mean margin of error of 5.9 to 6.8 years.
The microbiome does change in a somewhat predictable manner in the context of ageing.
It may be possible to refine the clock further for much higher accuracy.
Next step is to identify the specific bacterial populations influencing rate of ageing.
Provides a starting point for building host ageing, gut community succession into single narrative.
