Stochastic and deterministic controls in ageing process
Yukinobu Arata (Cellular Informatics Laboratory, RIKEN)
Animals are born after a miraculous embryogenesis, and after the birth, they age and eventually die. Basically, ageing is considered as a “wearing out” process of biological systems. However, such a strong self-organizing force during embryogenesis would draw us to think why animals do not live forever based on the force? To scientifically approach this thought, we can set several questions; 1) what kind of statistical laws the “wearing out” process is governed by, 2) how much deterministic controls are involved in the ageing process, 3) how much we can predict or artificially manipulate our lifespan? To address these questions, I have been preparing for a recording system for motions and physiological change of a tiny multicellular animal, C. elegans at video rate during their lifespan (~20 days). This recording system will generate unprecedentedly long time series data in Biology. In this meeting, I would like to discuss which existing mathematical frameworks developed in Physics and Mathematics can be applicable for these Biological issues, and would like to discuss the limit of the mathematical frameworks.

Spin hydrodynamic generation: A new power generation at nanoscale
Mamoru Matsuo (University of Chinese Academy of Sciences, China)
In this talk, I would like to introduce a new power generation using the electron as a nanoscale spinning gear. Electron, the most common elementary particle to us, is spinning perpetually since the beginning of the universe and the spinning motion is the origin of the magnetism. Recently we discovered interconversion mechanism between the electron’s spinning motion and electric power, and experimentally demonstrated it using liquid metal flow. We believe this will be a power source of nanorobots in the future.
