Abstract: High-dimensional tissue imaging generates highly complex 3D data containing multiple biomarkers, making it challenging to identify biologically relevant regions without an expert user specifying manual labels for regions of interest. We introduce an approach to automatically identifying regions of interest (ROIs) in the 3D microscopy data. Our approach is based on a novel self-supervised multi-layer graph attention network (SSGAT), coupled with a React interactive interface wrapped around Vitessce. SSGAT employs an adversarial self-supervised learning objective to identify meaningful immune microenvironments through marker interactions. Our method reveals complex spatial bioreactions that can be visually assessed to assess their distribution across tissue.

Cloning isn’t just for celebrity pets like Tom Brady’s dog
This week, we heard that Tom Brady had his dog cloned. The former quarterback revealed that his Junie is actually a clone of Lua, a
