The samples were also tested for things MED does not currently require, such as aerobic bacteria and coliform, the latter of which can be a sign of potential pathogens, Singer said.
The researchers first compiled a list of genes found in modern aerobic and anaerobic bacteria, which they used to train a machine learning model to determine an organism’s oxygen use based on its genetic makeup.
After processing, the sponge powder contains precisely sized and shaped silica spicules that upon application may help exfoliate the skin, promote collagen production, open closed comedones (creating an aerobic environment to help kill C.
Machine learning (ML) was used to identify ancient aerobic bacteria, then using Bayesian statistical methods they estimated the time of their emergence, assuming that these oxygen-using bacteria evolved after the GOE.
