NOTE: A VIDEO VERSION of this blog entry also exists (slightly shorter and outdated to Apr. 2025) Life123 is an open-source platform for quantitative interactomics, aiming towards simulations of virtual biological cells or parts thereof – among other things. And it has a slogan: AI and Big Data aren't enough! We also need Dynamical modeling. What does it mean to say "engine for quantitative reactomics"? It means that we perform dynamical modeling of biological systems. And the initial focus is towards eventually creating whole-cell simulations. The platform consists of python libraries, which allow us to do in-silico experiments. Early this year, this project left the beta stage, after a few years of development. Motivation There's a practical motivation – and a conceptual one... The practical side is a simple one to state : about 90 percent of clinical-drug development fails . That’s appalling! And ...
