Vita umana, c’è un tetto teorico: 156 anni un cervello, 470 un corpo intero

Il fegato potrebbe funzionare per migliaia di anni: è il cervello che decide quando smettere. A dirlo, un nuovo modello sulla vita umana.

Gianluca Riccio

A photorealistic, editorial-style scientific illustration showing a dramatic visual contrast between two types of biological tissue at a microscopic level: on one side, a vibrant, actively regenerating liver tissue with dividing cells glowing in warm amber and gold tones, symbolizing renewal and vitality; on the other side, dense, intricate cortical neurons rendered in cool blue and silver, static and unchanging, bearing the weight of accumulated time. The two tissue types are separated by a subtle visual boundary, suggesting asymmetry and biological tension. In the background, a faint hourglass-like structure emerges from abstract anatomical forms, evoking the passage of time and biological limits. The overall mood is contemplative and scientific, with a slightly dramatic, high-contrast lighting reminiscent of medical imaging meets fine art photography. No text, no labels, no branding.
