Is it real physics?
To describe biomembrane properties, including their biological functions, the following need to be fully solved: interactions in liquid systems with partial order, ergodicity and relaxation, orientational fluctuation and alignment tensors, quantum transitions, second-order phase transition mechanisms and long-range correlations.
For the non-expert, all these sound sufficiently exotic to belong to physics. But what would an expert say? What are we after in this research? One thing: can we explain how biological systems, e.g. biomembranes, work based on the only interaction that is manifested in the living systems, namely electromagnetism? You see, physicists cannot invent new forces. But how can we then explain an overwhelming complexity of biological functions based on this one force? The degrees freedom business mentioned in one other question above will come in very handy.
