Scientists at the Massachusetts Institute of Technology and Harvard last month described in the scholarly journal Cell how they used a deep learning neural network to identify a molecular compound that's different from most antibiotics. They showed that when the compound is injected in mice, it fights bacteria that no existing drug can eliminate. The discovery even has implications for fighting the coronavirus that is causing the Covid-19 disease.
