Approach 1, macro science, in palette D, bold color field.

Extreme close-up microscopy-style photograph of a dense colony of rod-shaped, slightly branched Bifidobacterium cells, rendered as real textured organic forms with soft translucent walls and subtle surface detail. The cells are warm cream and ivory, clustered in the center and thinning toward the edges. The whole backdrop is a saturated tomato-red to orange field, smooth and out of focus, so the bacteria stand out in sharp contrast. A few scattered tiny crystalline metabolite specks glow faintly electric green (#00e676) near the colony. Camera angle is straight-on, slightly oblique, with a very shallow depth of field. Lighting is soft, diffuse backlight with gentle rim highlights on the cell edges and no harsh shadows. The mood is vivid, curious and hopeful, scientific but warm, with no blue cast anywhere.

Ovaj crijevni mikroorganizam proizvodi 5‑AVAB – molekulu koja smiruje upalu starosti

BY NOVA CHEN · 2. stu 2026.

Crijevni mikroorganizam koji postepeno nestaje s godinama mogao bi imati veći učinak na zdravlje nego što smo mislili. Istraživanje objavljeno u *Nature Aging* identificira *Bifidobacterium pseudocatenulatum* kao stalno smanjenu vrstu u starijim kineskim kohortama. U studiji na prirodno starim štakavima oralna primjena ove bakterije ublažila je multiorganu upalu povezanu sa starenjem i produžila zdravi životni vijek. Autori su učinak povezan s metabolitom 5‑AVAB, čije razine također padaju s godinama kod ljudi. Evo što je istraživanje pokazalo, što još nije potvrđeno na ljudima i kako razumno razmišljati o ovoj temi.

$Approach: Macro science. Palette: D, bold color field. Extreme close-up photograph of taurine crystals, long translucent needle-like prisms with sharp faceted edges, bundled and crossing in a loose cluster. They rest on a saturated tomato-red matte acrylic surface. The camera is a low three-quarter angle with a shallow depth of field, so the front crystals are razor sharp and the back ones melt into soft red blur. A hard, warm key light from the upper left makes the facets glint white and throws crisp, thin red-tinted shadows. A single crystal tip in the foreground catches a tiny edge of electric green (#00e676) light refracted through the glass-like prism. The mood is bold, tense and curious, which suits a paradox in the findings. The image has no text, no labels, and no blue cast.$

Taurin raste s godinama – zašto je veća doza poboljšala zdravlje starijih miševa?

BY NOVA CHEN · 25. lis 2026.

Studija objavljena u časopisu *Cell* otkriva da razine taurina u krvi rastu kako kod ljudi, tako i kod miševa, a dodatni unos taurina produžio je životni vijek i smanjio smrtnost od sepse kod starijih životinja. Istraživanje je također predložilo mehanizam kroz koji makrofagi otpuštaju taurin kao signal opasnosti, što aktivira NLRP3 inflammasom, dok povratak taurina u stanicu ublažava alarm. Ljudski podaci su samo promatrački, a rad ne testira doze suplementacije kod ljudi.

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.
