You never know, maybe you'll end up contributing to our understanding of life, maybe (indirectly) even save a few lives!
life science is one of potential applications if there is an interest and money.
But if you mean in general if you're capable of looking at protein pathways where each protein catalyses a step in the pathway, that's definitely interesting. If a certain person has a flawed gene coding for protein X, that could indeed cause a problem.
To find valid answers, you might need to eg. track nodes and states in a graph, to figure all the consequences of a break. Not all types of storage systems/engines are equally good at that.
Yes, I built system which traverses paths in graphs with 1B nodes and 10B links in 1h on affordable server. But that's only one part of the puzzle.
