Approach: conceptual metaphor, with a natural palette.

A single walnut is cracked open on a rough wooden board, and its two halves sit slightly apart. The halves are shot in tight macro from a low three-quarter angle. The walnut's brain-like folds are the focus. Between the halves, a thin cluster of fine, dark brown tannin-stained fibers stretches like a bridge. Beside it sits a small pile of shell fragments with a few strands of green walnut husk. A small, sharp, electric green (#00e676) leaf catches the light at the edge of the frame. The background is a softly blurred window-lit kitchen garden in leafy greens and warm earth tones. Soft natural daylight comes from the left and gives gentle shadows and visible texture on the nut's ridges. The mood is calm, curious and quietly scientific, with a fresh morning feel and no blue cast.

Urolitin A: sporedni proizvod oraha iz creva povezan sa debljinom korteksa mozga

BY NOVA CHEN · 3. нов 2026.

Jedite orahe, a vaše crevne bakterije pretvaraju njihove elagitanine u urolitine – spojeve koji mogu da utiču na to koliko dobro vaš mozak stari. U dvogodišnjoj MRI podstudiji WAHA‑triala, veći porasti urolitina A, C i C‑glukuronida bili su povezani sa očuvanjem debljine korteksa kod učesnika koji su jeli orahe, pretežno u desnoj hemisferi. Odnos je bio jači kod osoba sa metabotypeom B. Ipak, radi se o asocijaciji unutar randomizovanog studija, a ne o dokazima uzročnosti, i ne odnosi se direktno na suplemente urolitina A.

Approach: Macro science, with a Bold color field palette.

Extreme close-up microscopy-style image of a single microglial cell with fine, branching processes, rendered with the real texture of fluorescence-stained tissue: translucent, slightly granular cell body, delicate ramified arms reaching across the frame. Shot from straight overhead through a microscope objective with shallow depth of field, so the outer branches soften into blur. The cell is a luminous, warm ivory-white with a few small electric green (#00e676) points of light along its branches. Behind it is a saturated, even magenta backdrop with subtle tissue grain. Lighting is crisp and backlit, with gentle glow around the edges and no harsh shadows. The mood is curious and precise, with a quiet sense of renewal. No text or labels.

Studija na miševima: NR pomera stare moždane ćelije ka mlađem stanju

BY NOVA CHEN · 31. окт 2026.

U novoj studiji u časopisu *GeroScience* 22‑mesečni miševi kojima je osam nedelja pre dana nikotinamid ribozid (NR) pokazali bolje rezultate na testovima memorije i izgradnje gnezda. Njihove moždane imunološke ćelije izgledale su više kao kod mladih miševa. Ovo je studija na životinjama i ne dokazuje iste benefite kod ljudi. Doza od 400 mg/kg znatno je viša od one koju ljudi uzimaju, a istraživanje je obuhvatilo samo mužjake.
