Google DeepMind has revealed a new artificial intelligence (AI) tool that can predict the molecular impacts of tweaking any one of the billions of letters that make up our genetic code. On Sept. 8, Google's AI powerhouse announced a freely available database called AlphaGenome Atlas, which contains data on 9 billion possible changes to the human genetic code and estimates how these changes will affect different tissues and cellular processes. What's more, the tool spits out a simple score to help scientists quickly weigh the knock-on impacts of these changes. How a sequence of 3 billion or so letters of chemical code is packaged, delivered and read to create a human life is a major question ...
