Rare coding SNP in DZIP1 gene associated with late-onset sporadic Parkinson's disease

We present the first application of the hypothesis-rich mathematical theory to genome-wide association data. The Hamza et al. late-onset sporadic Parkinson's disease genome-wide association study dataset was analyzed. We found a rare, coding, non-synonymous SNP variant in the gene DZIP1 that confers increased susceptibility to Parkinson's disease. The association of DZIP1 with Parkinson's disease is consistent with a Parkinson's disease stem-cell ageing theory.

High-Throughput Biologically Optimized Search Engineering Approach to Synthetic Biology

Synthetic Biology is the new engineering-based approach to biology that includes applications of designing complex biological devices. At present, it is not yet clear what will emerge as the defining principles of Synthetic Biology. One proposed approach is to build Synthetic Biology around the classical engineering principles of standardization, modularity/decoupling and abstraction/modeling to facilitate component-based design. In this article we suggest and discuss an alternative paradigm, which we call High-throughput Biologically Optimized Search Engineering (HT-BOSE). Stemming from directed evolution, in HT-BOSE the focal point is a biological knowledge based rational optimization of the search process in the space of device design possibilities. The HT-BOSE approach may also be relevant in other contexts and we briefly highlight how it could be applicable to the development of multi-drug cocktails in a biomedical setting.

Prediction in the Hypothesis-Rich Regime

We describe the fundamental difference between the nature of problems in traditional physics and that of many problems arising today in systems biology and other complex settings. The difference hinges on the much larger number of a priori plausible alternative laws for explaining the phenomena at hand in the latter case. An approach and a mathematical framework for prediction in this hypothesis-rich regime are introduced.
