In addition to things with long time horizons, it makes sense to look at things that have little profit-incentive for startups or companies to work on. One example would be nutritional supplements. It's fairly expensive to do a good nutritional study, and there's no good way to make money off of the results (since companies can't patent supplements). So, no one funds good studies on supplements. At the same time, finding out that certain supplements have positive or negative effects would be great for humanity as a whole. This also goes for nutrition in general, though supplements are easier to research.
