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 ·

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.
Approach: conceptual metaphor. Palette: bold color field. A single steel bathroom-style analog tape measure, pulled taut and wrapped around a ripe, glossy yellow-orange pear lying on its side, with the tape's tip locked at the same unmarked point, suggesting a waistline that did not shrink. The pear sits on a saturated magenta seamless backdrop, shot from a low three-quarter angle with a shallow depth of field, the stem sharp and the background softly blurred. Hard but slightly diffused studio key light from upper left casts a crisp, short shadow in deeper magenta on the surface. A tiny electric green sticky dot marks the tape's end, with no numbers or writing visible. Mood: playful, skeptical, deadpan, scientific restraint rather than hype.

Nedeljni rapamisin tokom godine: Bezbedan, ali da li se visceralna mast promenila?

BY REX MERIDIAN ·

Svi žele da znaju da li nedeljna doza rapamisinа može da smanji visceralnu mast i poboljša zdravlje, a PEARL studija donosi iznenađujući odgovor. Nakon 48 nedelja praćenja kod zdravih odraslih, primarni ishod – visceralna mast – nije se promenio, iako je profil bezbednosti bio sličan placebo grupi. Neki sekundarni pokazatelji, poput povećanja mišićne (lean) mase i smanjenja bola kod žena koje su uzimale 10 mg, kao i bolji osećaj blagostanja kod onih na 5 mg, sugerišu moguće koristi. Međutim, to su podgrupne i samoprijavljene naznake, lek je bio pripremljen u apotekama (kompaundovan) i još uvek nije dokazano da produžava ljudski životni vek. Evo šta podaci zaista podržavaju, a šta ne.
A wide landscape editorial photograph of a minimalist laboratory-meets-wellness still life on a pale, warm-gray stone countertop, softly lit by diffused morning window light from the left. In the center foreground, a small amber glass supplement jar with a plain matte white label sits beside a scattering of fine white powder and a few loose white capsules on a ceramic dish. Next to it rests a clean, open notebook with faint hand-drawn line graphs, two diverging curves rising gently, one slightly higher than the other, drawn in muted sage-green and charcoal ink. A slim brass pen lies across the page. In the soft-focus midground, a delicate glass beaker filled with clear liquid catches a thin streak of light, casting a gentle caustic shimmer across the stone. A sprig of dried eucalyptus and a small sliver of citrus peel add organic texture. Behind them, an out-of-focus wall of pale oat-colored tiles and a floating wooden shelf holds a few blurred ceramic vessels and a small potted fern. The color palette is calm and editorial: warm creams, sage green, soft amber, muted terracotta accents, and touches of charcoal. Shallow depth of field with a crisp focus on the jar and notebook, creamy bokeh in the background. Subtle film-like grain, natural shadows, and generous negative space on the right third of the frame, suitable for headline overlay. The mood is thoughtful, measured, and trustworthy, like a contemporary science and wellness journal cover: modern, tactile, quietly optimistic, and grounded rather than hyped.

Kalcijum‑alfa‑ketoglutarat produžio životni vek ženki miševa za čak 16,6 % – šta to zapravo znači (a šta ne) za ljude

BY DR. SYNAPSE ·

Studija iz 2020. u časopisu *Cell Metabolism* otkrila je da je ishrana sredovekih miševa hranom koja sadrži 2 % kalcijum‑alfa‑ketoglutarata produžila medijani životni vek ženki za čak 16,6 % i smanjila slabost. Efekat je bio manji u drugom kohortu (10,5 %), a dobitci kod mužjaka nisu bili statistički značajni. Istraživači povezuju korist sa nižim sistemskim zapaljenjem i predloženim porastom IL‑10. Međutim, ovo je bio eksperiment samo na miševima i ne dokazuje da AKG produžava životni vek kod ljudi. U nastavku su prikazani podaci, razlike u odnosu na marketinške tvrdnje i razlog zašto CaAKG treba da bude na listi za praćenje istraživanja, a ne u potvrđenom protokolu.
A serene editorial still life shot from a slightly elevated angle on a pale travertine surface, bathed in soft morning window light with gentle long shadows. At the center sits a small matte ceramic bowl in warm oatmeal tone, holding a fine mound of white crystalline powder, with a delicate wooden scoop resting beside it. A few grains are scattered naturally across the stone. To the left, a clear glass of water catches the light, throwing a subtle caustic shimmer onto the surface. To the right, a neatly arranged trio of translucent amber glass capsules and a single sprig of dried eucalyptus add organic texture. In the softly blurred background, a sage-green linen cloth drapes across the frame, and a vintage brass hourglass stands upright, its sand halfway through. This is a subtle nod to aging and time. A small open notebook with faint, abstract hand-drawn line graphs trending gently downward, with no legible text, rests at the edge of the composition, with a slim pencil placed across it. The palette is calm and modern: creamy ivory, warm sand, muted sage, soft terracotta, and touches of honey amber. The mood is quiet, thoughtful, and scientific without being clinical, like a contemporary wellness and science magazine cover. Shallow depth of field keeps the powder bowl crisp, with creamy bokeh behind it. Generous negative space on the right side of the wide 16:9 frame leaves room for headline overlay. Fine film-like grain, natural color grading, and minimalist composition give it a refined, trendy journal feel.

Taurin, jeftini aminokiselinski spoj koji je produžio životni vek miševa za do 12 %, a kod ljudi opada s godinama

BY DR. SYNAPSE ·

Studija iz 2023. godine u časopisu *Science* otkrila je da koncentracija taurina u cirkulaciji opada sa godinama kod miševa, majmuna i ljudi. Suplementacija sredovječnim miševima produžila je medijan njihovog životnog veka za otprilike 10‑12 % i poboljšala zdravstveno stanje i kod glodara i kod majmuna. Spoj je delovao na ćelijsku senescencu, oštećenje DNK, disfunkciju mitohondrija i hroničnu nisku upalu. Ljudski podaci su i dalje samo posmatranja, a doze za miševe bi se prevele na nekoliko grama dnevno, tako da dokaz još nije čvrst. Istraživači upozoravaju da su potrebna klinička ispitivanja pre nego što se taurin tretira kao pilula za anti‑starenje.
