A wide editorial still life on a pale, warm-toned concrete surface in soft morning window light. In the center-left, a shallow matte ceramic bowl holds a small pile of bright red coffee cherries with glossy skins, a few sliced open to reveal pale mucilage and paired green-tan beans. Beside it, a small glass dish of fine, golden-brown powdered extract with a tiny wooden scoop resting on its edge. A sprig of coffee plant leaves, deep green and waxy, arcs across the foreground.

On the right side, slightly out of focus, a sleek road cyclist's handlebar and a matte black water bottle lean against a light plaster wall, suggesting athletic training without showing a person. A minimalist analog stopwatch with a clean white face and thin black hands sits in the mid-ground, angled toward the camera, its hands paused near the fifteen-minute mark. A folded linen cloth in oatmeal beige and a single small espresso cup with a thin crema ring add quiet texture.

The color palette is restrained and modern: cherry red, sage green, cream, soft terracotta, and charcoal accents. Light comes from the left, casting long, gentle shadows with a subtle warm glow and a hint of dust in the air. Shallow depth of field with crisp focus on the cherries and stopwatch, creamy bokeh in the background. Composition leaves open negative space in the upper right for a headline overlay. The overall feel is a clean, trendy health-and-science magazine cover: tactile, natural, minimal, and calm, shot in a 16:9 landscape frame with fine film-like grain and true-to-life tones.

Ekstrakt od kavevih bobica: 200 mg kaveina povećalo rad kod biciklista za 4,6 %

Niska doza od 200 mg kaveina iz ekstrakta cijele kaveve bobice pomogla je obučenim biciklistima da u 15‑minutnom testu proizvedu 4,6 % više rada. Ideja da takav ekstrakt ubrzava popunu glikogena u mišićima nije potkrijepljena podacima. Radi se o randomiziranom, dvostruko‑slijepom, križanom ispitivanju na 12 biciklista, financiranom od strane proizvođača. U tekstu su prikazani rezultati, ono što studija ne dokazuje i tko bi mogao imati korist od dodatka.
