Innovations at the intersection of artificial intelligence and biology are dramatically improving cancer tissue analysis and cellular trajectory mapping. Mount Sinai researchers introduced MARQO, an AI-driven tool to expedite tumor slide examination, while the Chan Zuckerberg Biohub developed Ultrack, enabling scalable and accurate cell tracking across 3D embryos using integrated segmentation and linking. Furthermore, new multi-omics studies illuminate drug mechanisms and immune profiling in oncology, offering refined therapeutic insights.
