Google’s New AI Predicts Molecular Behavior, Which Could Supercharge Drug Discovery

 Google’s New AI Predicts Molecular Behavior, Which Could Supercharge Drug Discovery


Google DeepMind, the company’s artificial intelligence research lab, has a new molecular prediction model called AlphaFold 3 that it says can predict the interactions of “all life’s molecules” with at least 50% improved accuracy over past models. This means scientists could develop drugs that target diseases more effectively, Google said in a blog post and in a paper published in the journal Nature on Wednesday. 

AlphaFold 3, available to researchers for free, will allow scientists to test different structures composed of proteins, DNA and RNA to generate predictions of how different substances might interact.

Doing this type of predictive modeling with AlphaFold 3 could greatly speed up research while also reducing costs — Google says that in the past, creating an experimental protein structure prediction would take years and cost hundreds of thousands of dollars. 

Google purchased DeepMind in 2014 for an estimated $400 million to $650 million to expand its AI capabilities. DeepMind made headlines for creating systems that could beat the world’s best Go, chess and shogi players. It soon started making advancements in protein folding and crystalline structure discovery.

AlphaFold 2 was used to help in malaria and cancer treatments as well as enzyme design, Google says. AlphaFold 3 takes things a step further by also looking at the “broad spectrum of biomolecules,” which could aid in the discovery of biorenewable materials to drug design and genomics research.

Google said it’s already been used to predict hundreds of millions of structures that would have taken “hundreds of millions of researcher-years at the current rate of experimental structural biology.”

Isomorphic Labs, the sister company to DeepMind, is already working with pharmaceutical companies to develop new treatments.

DeepMind’s advancements in helping scientific research isn’t only good for humanity but also helps give Google a good brand image as a tech company hoping to use its power and expertise to help solve monumental challenges. Advancements at DeepMind can also help Google enter new markets.
