Something that should exist

Science people! You know that website where you make up a list of bands you're interested in seeing live and they notify you when those bands are coming to your hometown? Is there something like that for scientists and their publications? If, for example, I'm interested in the work Barry Green is doing with the effects of temperature on taste sensitivity (SO cool, seriously) and I want to know when his lab publishes new work, is there a service that will notify me?

If not, I might have to make one. I feel like this would be enormously popular.
