MIT researchers have used a machine-learning algorithm to discover a new antibiotic compound. This new approach has revealed what is believed to be one of the most powerful antibiotics known to man and has even cleared infections in two mouse studies. Several other antibiotics were also discovered and are currently being tested by scientists. “The machine learning model can explore, in silico, large chemical spaces that can be prohibitively expensive for traditional experimental approaches,” commented Regina Barzilay. Machine learning programs similar to the one used in this study are currently being used in other research to quickly and efficiently generate new information.
