生命系统中的信息处理
Information processing in living systems
摘要：
生命既依赖于能量的流动，也依赖于信息的流动。在这里，我们回顾了许多努力，使这种直觉准确。从信息论的构建模块开始，我们探索了可以直接测量生物网络中的信息流的例子，或者更一般地说，信息论的思想被用来指导实验分析。感兴趣的系统范围从单个分子（蛋白质家族的序列多样性）到生物群体（鸟群中的速度分布），以及介于两者之间的所有尺度。许多这些分析的动机是生物系统可能已经进化到优化信息的收集和表示的想法，我们审查了这种优化的实验证据，再次在广泛的尺度。
英文摘要：
Life depends as much on the flow of information as on the flow of energy. Here we review the many efforts to make this intuition precise. Starting with the building blocks of information theory, we explore examples where it has been possible to measure, directly, the flow of information in biological networks, or more generally where information theoretic ideas have been used to guide the analysis of experiments. Systems of interest range from single molecules (the sequence diversity in families of proteins) to groups of organisms (the distribution of velocities in flocks of birds), and all scales in between. Many of these analyses are motivated by the idea that biological systems may have evolved to optimize the gathering and representation of information, and we review the experimental evidence for this optimization, again across a wide range of scales.
