Approach: conceptual metaphor. Palette: D, bold color field.

A single AA-style cylindrical battery stands upright, fully charged, on a seamless saturated mustard-yellow backdrop. Beside it sits a matching, untouched, slightly dusty glass jar of marbles, so the charge shows no visible link to any result. More precisely, a bright tomato-red extension cord plugs into the battery's top. Its other end curls away unconnected, lying on the floor beside an unlit incandescent bulb. A small electric green LED glows on the battery's side as the only green accent. Camera: low three-quarter angle, 50mm lens, shallow depth of field, with the bulb softly blurred in the foreground. Lighting: hard, clean studio key light from the upper left, with crisp shadows falling to the right on the yellow surface. Mood: puzzled, wry, a full power source that fails to light anything.

Nikotinamid ribozid udvostručio NAD+, ali nije poboljšao pamćenje

BY NOVA CHEN · 27. lis 2026.

Suplement je udvostručio ključnu molekulu u krvi, ali pamćenje nije pomaknulo ni atoma. U 12‑tjednoj randomiziranoj studiji na starijim osobama s amnestičnim blagim kognitivnim poremećajem, nikotinamid ribozid povećao je NAD+ otprilike dva puta, no nije poboljšao kogniciju, ukupni protok krvi u mozgu niti krvni tlak. Jedna istraživačka naznaka ukazala je na mogući porast protoka krvi u hipokampusu, ali to nije dokaz. Evo što je studija zaista pokazala, koja su njezina ograničenja i što to znači ako razmišljate o kupnji NAD+ pojačivača.

Approach: macro science, a lithium-themed image built around the actual metal and tissue. Palette: bold color field in saturated teal.

Extreme close-up photograph of a single freshly cut piece of silvery lithium metal, its surface partly tarnishing to grey and matte black at the edges, resting on a thin slice of translucent brain tissue on a glass microscope slide. The slice shows fine pink-grey folds and a few dark clumped plaque-like specks. The backdrop is a smooth saturated teal field, with the slide placed diagonally. Shallow depth of field keeps the metal edge razor sharp while the tissue softens toward the corners. Lighting is a crisp, slightly warm side light from the left, with a small specular highlight on the metal and a soft shadow on the teal. A tiny electric green reflection glints in the glass edge. The mood is quiet, investigative and precise. Shot from a low 30-degree angle, with no text or labels.

Mikroelement koji izblijedi iz mozga prije Alzheimerove bolesti

BY DR. SYNAPSE · 21. lis 2026.

Prelomno istraživanje objavljeno u *Nature* s Harvardovih laboratorija otkrilo je da je litij jedini metal značajno smanjen u mozgima osoba s blagim kognitivnim poremećajem. Smanjenje litija kod miševa za otprilike polovicu dovelo je do nakupljanja amyloida, patološkog tau‑proteina, upale i gubitka pamćenja, dok je niskodoziran litij‑orotat spriječio te promjene. Iako su rezultati do sada ograničeni na životinje i litij nosi rizike za bubrege i štitnjaču, istraživanje otvara nova pitanja o ranoj ulogi mikroelemenata u Alzheimerovoj bolesti.
