Approach: conceptual metaphor. Palette: bold color field.

A single glass hourglass stands center-frame on a saturated tomato-red seamless backdrop, photographed at a low three-quarter angle just above tabletop level. The upper chamber holds only a thin layer of pale sand, while the lower chamber is heaped with it. A narrow stream of fine grains falls through the neck, and a few of them glow faintly electric green (#00e676) as they pass the waist. Beside it, a second hourglass has been tipped onto its side, its sand motionless. This stands for the age cutoff. Soft, large-source studio light comes from the upper left and casts crisp, warm-grey shadows on the glossy red surface. Fine scratches and dust show on the glass. The shallow depth of field blurs the background hourglass slightly. The mood is playful but precise, curious and a little skeptical.

2 grama karnosina poboljšalo brzinu mozga, ali samo do 35 godina

BY NOVA CHEN · 23. lis 2026.

Kliničko ispitivanje koje je prvobitno bilo usmjereno na obranu od zagađenja zraka otkrilo je neobičnu vezu između karnosina i funkcije mozga. Kod odraslih od 23 do 35 godina, doza od 2 grama dnevno tijekom najviše 12 tjedana bila je povezana s bržim i učinkovitijim kognitivnim radom, dok starije skupine nisu pokazale značajne učinke. Važno je napomenuti da je ovo post‑hoc, podgrupna analiza nasumičnog ispitivanja na 299 sudionika. U nastavku sažimamo što je NEAT studija stvarno otkrila, u čemu se karnosin razlikuje od beta‑alanina i tko bi (i tko ne bi) trebao obratiti pažnju na ove rezultate.
