Algorithm-generated comparisons among the genomes of cells from 450 tissue samples: The analysis revealed a striking similarity (red colors, upper right rectangle) in tRNA signatures among cancerous cells and healthy dividing cells, as well as a degree of similarity among the non-dividing cells (red colors, lower left rectangle), whereas no such similarity (blue) was found when dividing cells were compared with non-dividing ones

Natural healing process of fractured bones. (A) Healing begins with a collection of blood and inflammation at the fracture site. (B) Soft callus (purple) is formed, which develops into the bidirectional growth plate at the concave side of the fracture site. (C) The growth plate drives bone growth in opposite directions. The result is a jack-like mechanical effect that moves the fragments toward straightening (red arrows). (D) New bone tissue is formed (orange). (E) The shape of the bone is fine-tuned by rem
