--- res: bibo_abstract: - 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.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Gasper foaf_name: Tkacik, Gasper foaf_surname: Tkacik foaf_workInfoHomepage: http://www.librecat.org/personId=3D494DCA-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-6699-1455 - foaf_Person: foaf_givenName: William foaf_name: Bialek, William foaf_surname: Bialek bibo_doi: 10.1146/annurev-conmatphys-031214-014803 bibo_volume: 7 dct_date: 2016^xs_gYear dct_language: eng dct_publisher: Annual Reviews@ dct_title: Information processing in living systems@ ...
