OK, I'll give it a shot. I am no expert in any of these fields but I know that this could be valuable to society. Perhaps some work in the field already exists. If so, I am sure HN readers will point that our quickly. The problem: The treatment or removal of tumors. Issue: You can damage surrounding tissue, nerves and structures in the process. Current methods: Mechanical extraction. Just cut them out. Potential for damage to surrounding structures can be significant. Gamma "knife": Focused multi-dosage radiation used to "kill" the tumor. Does not really remove a tumor so much as it stops growth without having to make an incision. Common for cranial tumors. Other radiation: Can be devastating. Desirable future solution: Engineer molecules that are precisely designed to affect the tumor and spare non-afflicted structures. Perhaps this takes the form of a molecule that simply becomes a marker of sorts that some other technology (gamma knife?) can use to guide the "attack" with great accuracy. In an ideal sci-fi world one would be able to administer a substance containing molecules that can bind to the tumor and actually dissolve it. Take the example of something like an acoustic neuroma (my wife is a doctor, she suggested this example). This is a tumor that grows within the cranial cavity and around the acoustic and facial nerves. Mechanical removal usually means certain damage to the auditory never (causing deafness on that side) and potential damage to the facial nerve (causing that half of the face to drop and have not muscle tone). This type of tumor is usually either cut out or stopped in it's tracks using gamma knife. In most cases the person ends-up deaf on one side. This means the loss of acoustically locate sound, brain-computed noise reduction and even balance problems. It'd be interesting to see a molecular "attack" type solution that could dissolve the tumor while staying away from the brain and not impacting the nerves at all. The treatment could also take the form of a substance that is actually injected into the tumor (rather than the entire bloodstream). Don't know if this is the kind of problem that could be tackled with molecular dynamics on a supercomputer. Even if you could, there might not be enough data available or commonality in tumorous cells to develop "key" molecules that could target them.
