I think there are lots of answers to Mike's question. Just to give one, I gave a talk in 2003 published with Tim Porter as `Category theory and higher dimensional algebra: potential descriptive tools in neuroscience', Proceedings of the International Conference on Theoretical Neurobiology, Delhi, February 2003, edited by Nandini Singh, National Brain Research Centre, Conference Proceedings 1 (2003) 80-92. arXiv:math/0306223 which went well. A web search on "category theory and biology" shows lots more. Category theory has (at least) two aspects. One as a kind of meta theory for discussing and relating mathematical structures; another as giving a range of algebraic, or more generally, mathematical, structures, often with algebraic operations with partial domains. We can expect these to have over time surprising applications Ronnie -- [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
