New research from the University of Chicago shows that dentine, the inner layer of teeth that transmits sensory information to nerves inside the pulp, first evolved as sensory tissue in the armored exoskeletons of ancient fish.

SeaSplat is an image-analysis tool that cuts through the ocean’s optical effects to generate images of underwater environments reveal an ocean scene’s true colors. Researchers paired the color-correcting tool with a computational model that converts images of a scene into a three-dimensional underwater “world” that can be explored virtually. 

This paper proposes strategies for the robust interpretation of Pb isotopes for geologic applications, focusing on source tracking and model ages. It provides a framework for accurate model age determination and magma source characterization, with recommendations for standardized data reporting.
