A side profile of a human head formed by glowing blue lines and circuit-like patterns, suggesting a digital or artificial intelligence representation. The face appears semi-transparent and geometric, with interconnected nodes and pathways extending outward. Binary code is faintly visible on the left side, while a blurred laptop sits in the background, reinforcing a technology-focused setting.

A highly detailed, abstract-looking microscopy image filled with tightly packed, irregular cell-like shapes. The scene is dominated by bright orange and blue outlines, with green streaks and patches weaving through the tissue, plus many small pink and purple clusters scattered throughout. The background is mostly black, which makes the fluorescent colors stand out strongly. Information about the image: To develop novel strategies targeting the tumor microenvironment in lung adenocarcinoma, the TME was stained for cell type specific markers and imaged on an Axioscan 7 Slidescanner.
