Bridging Machine Learning And Cosmological Simulations: Using Neural Operators To Emulate Chemical Evolution
In this work, we explore the potential of machine learning, specifically Neural Operators, to emulate the Grackle chemistry solver, which is widely used in cosmological hydrodynamical simulations.

On the Origin of Information Dynamics in Early Life
We hypothesize that predictable variations in environmental conditions caused by night/day cycles created opportunities and hazards that initiated information dynamics central to life’s origin.
