Abstract

Why life is complex and --most importantly-- what is the origin of the over abundance of complexity in nature? This is a fundamental scientific question which, paraphrasing the late Per Bak, "is screaming to be answered but seldom is even being asked". In these lectures we review recent attempts across several scales to understand the origins of complex biological problems from the perspective of critical phenomena. To illustrate the approach three cases are discussed, namely the large scale brain dynamics, the characterisation of spontaneous fluctuations of proteins and the physiological complexity of the cell mitochondria network.
边缘的生命:生物功能的复杂性和临界性
为什么生命是复杂的,最重要的是,自然界中过多的复杂性的起源是什么?这是一个基本的科学问题,用已故的佩尔•巴克(Per Bak)的话来说,“迫切需要回答,但却很少有人问”。在这些讲座中,我们回顾了最近在几个尺度上的尝试,从批判现象的角度来理解复杂生物学问题的起源。为了说明这种方法,讨论了三个案例,即大规模的脑动力学,蛋白质自发波动的特征和细胞线粒体网络的生理复杂性。
