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

Extreme close-up of a freshly sliced king oyster mushroom stem and gill edge, shot at a slight 30-degree overhead angle with a macro lens and shallow depth of field. The pale cream flesh shows individual fibrous hyphae and glistening moisture beads. Warm low-angle golden light rakes across from the left, turning the gill ridges into amber and copper lines with deep honey-brown shadows. A single tiny droplet on the cut surface catches a pinpoint of electric green reflection, as if lit from a hidden source. Background melts into out-of-focus burnished orange and chocolate tones. The mood is quiet, intimate and investigative, with real organic texture and no text.

Gljiva ‘vitamin dugovečnosti’ povećala NAD+ kod starih štakora putem H₂S prekidača

BY HELIX WARD · 17. окт 2026.

Ergothionein – gljivični spoj koji su nazvali „vitamin dugovečnosti“ – podigao je nivo NAD+ u mišiću i poboljšao izdržljivost kod starijih štakora. Efekat je ostvarен putem vodonikovog sulfida (H₂S) i aktivacije enzima cGPDH; kada se CSE ili cGPDH eliminišu, benefiti nestaju. Ipak, radi se o eksperimentima na životinjama, a efikasna doza za štakora je otprilike deset puta veća od uobičajenih doza kod ljudi.
