**Approach: Conceptual metaphor. Palette: Bold color field (saturated orange).**

A single halved orange sits on a seamless saturated tangerine-orange backdrop, shot from a low three-quarter angle with a macro lens. The flesh is shrunken and dried on one side, with the juice vesicles collapsed and pulled back from the rind. The other half is plump and glistening. The shrunken side leaves a visible gap inside the peel, which suggests lost brain volume. Hard, directional studio light from the upper left throws a crisp, warm-neutral shadow across the backdrop. Tiny droplets of juice catch the highlights. A thin electric green leaf stem rests beside the fruit as a small accent. The mood is vivid and clean, with a quiet tension between fullness and depletion. There is no text and no blue cast.

Niska razina vitamina C u krvi povezana s manjim volumenom mozga kod starijih osoba

BY DR. SYNAPSE · 19. lis 2026.

Studija na 2 044 starija Japanca otkrila je da je niža razina vitamina C u plazmi neovisno povezana s manjom gustoćom sive tvari u odnosu na veličinu glave i slabijom povezanošću zadane mreže (default mode network) na 3 T MRI‑ju. Asocijacije su ostale značajne i nakon kontrole za dob, dijabetes, krvni tlak, pušenje, konzumaciju alkohola i tjelesnu aktivnost. Međutim, dizajn je poprečni i promatrački, pa ne može dokazati da suplementi vitamina C sprječavaju smanjenje volumena mozga. U nastavku objašnjavamo što rezultati znače, tko je najugroženiji i kako postići zdravu razinu vitamina C kroz prehranu i razborito suplementiranje.

Approach: macro science. Palette: warm (amber and honey).

Extreme macro photograph of a single golden droplet of DHA-rich fish oil suspended at the tip of a glass pipette, shot at eye level with a shallow depth of field. Inside the droplet, a tiny inverted reflection of a window shows through like a lens. Behind it, a softly blurred second droplet rests on a curved glass surface, catching a thin rim of light. Backlit by low golden-hour sunlight from camera left, producing glowing honey and copper tones, warm brown shadows, and delicate caustic patterns on the surface below. The oil shows fine texture, with microscopic bubbles and a slight viscous sheen. A faint electric green reflection glints along the pipette's edge. The mood is quiet, precise and hopeful, with a clean, uncluttered composition and generous empty space on the right. Photorealistic, no text.

DHA za mozak: 12 mjeseci usporenog gubitka volumena hipokampusa kod MCI

BY NOVA CHEN · 17. lis 2026.

Jedna godina suplementacije DHA usporila je gubitak volumena hipokampusa, memorijskog centra mozga, kod starijih osoba s blagim kognitivnim poremećajem (MCI). U randomiziranom, dvostruko‑slijepom studiju na 240 kineskih sudionika (219 je završilo), grupa koja je uzimala DHA nadmašila je placebo na testovima ukupnog IQ‑a, podtestu Informacije i zadatku Digitalni niz. Dnevna doza iznosila je 2 g suplementa (≈ 0,9 g čistog DHA). Rezultati mogu pojasniti zašto su studije omega‑3 kod zdravih osoba donosile mješovite zaključke – učinak je vjerojatno najizraženiji kod onih koji već pokazuju kognitivni pad.
