Can two seemingly disparate things — Google’s PageRank and hydrogen bonding in water — come together to create a tool that can help predict and map out the interactions between millions of molecules? It might sound far-fetched, but associate chemistry professor Aurora Clark of Washington State University and colleagues Barbara Logan Mooney and L. Rene Corrales have done just that and explained it in a paper published in the Journal of Computational Chemistry. It’s called moleculaRnetworks, but before we get into just what it does, let’s clear up some of those terms: PageRank is a patented algorithm that helps Google determine the relevancy of links, and hydrogen bonds (seen above) are relatively strong forces that attract molecules…
