9:00 On the Growth of Brain Tumours Enhancing imaging techniques, highlighting limitations of current imaging, quantifying therapy efficacy and estimating patient life expectancy. The prognosis for patients with high grade brain tumours (gliomas) is grim and the various treatment protocols such as surgery, radiation and chemotherapy cannot effect a cure. I shall describe, without any technical details, a simple but very practical model which uses patient data and brain scans to quantify the spatio-temporal growth of such brain tumours. Analysis of the model shows how difficult it is to decide on the tumour volume to be treated and shows why such treatments have so little success. The model simulations can estimate life expectancy for individual patients and show how it is possible to use the patient’s past record to predict the efficacy of possible treatments. Recent patient data indicates that calculating such an index of treatment efficacy is indeed a realistic aim. With the increasing discussion about cell phone use and a possible increase in brain tumours, I shall describe how to obtain an estimate for when a brain tumour started following detection.

16:20 Synthetic biocomputation: the possible and the actual Computation is defining trait of biological systems and a broad framework that captures the complex adaptive nature of molecules, cells and organisms. Computation is also at the core of the genotype-phenotype mapping, since it provides a natural framework to define function in a self-consistent way. The study of existing biological systems (from signalling cascades to ant colonies or brains) as well as the evolution of synthetic in silico networks performing computations reveals a number of nontrivial patterns of organization, sometimes in clear conflict with standard view of engineering or optimization. In spite of our increasing knowledge, there is a lack of a theoretical framework where computation and its possible forms is integrated within a general picture. Synthetic biology provides a new avenue where engineered molecular circuits can be implemented to perform non-standard computations. Here we review recent advances in the domain of multicellular synthetic computing and suggest a potential morphospace of computational systems including both standard and non-standard approximations.
