2SAP From molecules to systems, and eventually to life: high resolution Origins of Life research

Wed. Nov 15, 2023 2:00 PM - 4:30 PM Room A (Exhibition Room 211 (Bldg. 2, 1F))

Organizers: Tony Z. Jia (Tokyo Tech)、Kuruma Yutetsu (JAMSTEC)

Life began from a mixture of chemicals in the early Earth environment, and eventually resulted in the emergence of functional cells by passing through intermediates such as assemblies and systems. However, nearly every aspect of this historical transition leading to the emergence of life remains unsolved. In this symposium, we will highlight research focusing on each step of the origins of life, with an attempt to develop and increase the resolution of origins of life studies to more accurately reveal the step-wise transition from non-life to life.
