„Can physical laws explain living systems?
Our dream is to understand living systems and health based on physical principles. We explore the role of momentum conservation and show that it leads to the propagation of linear and nonlinear acoustic pulses in hydrated interfaces (e.g., lipid membranes). We hypothesize that such pulses are the basis for communication and integration in biology.
Of particular importance is the thermodynamic state of the interface. It affects not only propagation velocity, conductivity, morphological changes, but also enzymatic activity (which are essential for cellular biochemistry). We propose a physical basis of specificity.
Conservation of momentum and thermodynamics are the pillars of our approach to the formation of cells, tissues, and organs such as the brain. As such, it forms the basis for a new approach to health and disease.“



![3D visualisation of human neuronal tissue reconstructed by multi-scale X-ray phase contrast tomography. Neuronal cell nuclei are shown in yellow for the granule neurons in the dentate gyrus region of the hippocampus. Blood vessels are shown in red. By changing the X-ray optical magnification in the multi-scale recordings, one can zoom into regions-of-interest (red ovals). In these scans the resolution is high enough to resolve sub-structures of the nucleus, associated with different DNA packing regimes.
