Approach: Macro science. Palette: D, bold color field.

Extreme macro photograph of a single human T cell shown as a slightly bumpy, matte-textured sphere with fine microvilli, resting on a surface of smaller, out-of-focus cells. A faint electric green (#00e676) glow shows through a few lipid droplets inside its translucent membrane, hinting at fat-burning. The backdrop is a saturated magenta-violet field that fades from deep plum at the edges to bright magenta behind the cell. The camera sits at a low three-quarter angle with very shallow depth of field, so the foreground cell is crisp and the background melts into soft bokeh. Lighting is a soft, directional key from upper left with a thin rim light that picks out the membrane texture. The look is scanning-electron-microscope realism with subtle color, not cartoon. The mood is curious, quietly skeptical and precise. There is no text and no labels. The composition leaves open space on the right.

Urolitin A pomaknuo starenje T stanica za 4 tjedna – ali tu je zamka

BY NOVA CHEN · 21. lis 2026.

U randomiziranom istraživanju objavljenom u *Nature Aging* otkriveno je da četiri tjedna suplementacije urolitinom A pomiču imunološki profil zdravih sredovječnih odraslih. Zabilježeno je povećanje naivnih CD8⁺ T‑stanica i veća sposobnost sagorijevanja masti, ali učinak je vrlo malen – promjena od tek 0,5 postotna bodova. Studija je trajala četiri tjedna, obuhvatila 50 sudionika i mjerila biomarkere, a financirala ju je tvrtka proizvođač Mitopure.
