A scientific infographic titled "9 Hallmarks of Cancer." The image features a central circular diagram of a tumor microenvironment with blood vessels and immune cells, surrounded by nine colorful teardrop-shaped sections. Each section explains a hallmark, such as "Proliferative Signaling" or "Immune Evasion," listing associated genes like KRAS, TP53, and VEGF. The bottom includes a "Systemic Interactions" bar and the credit "www.thesciencenotes.com."

A detailed graphical abstract illustrating the microplastic lifecycle. At the top, "Anthropogenic Sources" like plastic waste, textiles, tires, and agriculture release primary and secondary microplastics. A central circular diagram shows their transport through Marine, Freshwater, Terrestrial, and Atmospheric compartments, highlighting chemical adsorption and microbial colonization. The bottom section depicts a food-chain transfer web leading to a human silhouette, illustrating exposure via ingestion and inhalation, resulting in systemic distribution and inflammatory responses.
