In this paper we demonstrate how literature mining can support experts in biomedicine on their way towards new discoveries. This is very important in complex, not yet sufficiently understood domains, where connections between different sub-specialities and fields of expertise have to be connected to fully understand the phenomena involved. As a case study, we present our preliminary literature mining work in the domain of ageing. The results confirm very recent discoveries about connections between diet and degenerative diseases, and indicate some concrete directions for further research needed to reveal the connections between microbiota and Alzheimer disease.
