Approach: macro science. Palette: bold color field (violet).

Extreme close-up of fisetin crystals, a small cluster of pale yellow needle-like flavonoid crystals with translucent, faceted edges, resting on a smooth glossy deep violet surface. The camera sits low at a shallow three-quarter angle with a very shallow depth of field, so the front crystals are razor sharp and the rest dissolves into soft magenta-violet blur. Lighting is a single crisp, slightly warm studio key from upper left that makes the crystal edges glow and throws long soft shadows across the violet. A few tiny electric green (#00e676) specks of reflected light catch on the crystal tips. The mood is precise, curious and quietly promising, like a sample under inspection, with plenty of clear violet space on the right side of the frame.

Fisetin Senolitik Memperpanjang Umur Tikus — Bukti pada Manusia Masih Hilang

BY HELIX WARD ·

Fisetin, flavonoid tumbuhan, muncul sebagai senolitik paling kuat di antara sepuluh senyawa dalam studi *EBioMedicine* 2018 yang banyak dikutip. Pada tikus tua, pemberian di akhir hayat menurunkan penanda senesensi, meredakan patologi terkait usia, dan memperpanjang baik harapan hidup median maupun maksimum. Namun, semua bukti masih berasal dari tikus dan laboratorium; belum ada uji klinis perpanjangan umur pada manusia. Artikel ini menjelaskan temuan peneliti, makna dosis yang diberikan, serta siapa yang perlu memperhatikan ketika studi pada manusia mulai muncul.

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.

Calcium Alpha‑Ketoglutarate Memperpanjang Umur Tikus Betina hingga 16,6 %: Apa Artinya (dan Tidak) Bagi Manusia

BY DR. SYNAPSE ·

Sebuah studi *Cell Metabolism* 2020 menemukan bahwa memberi tikus paruh baya diet yang mengandung 2 % calcium alpha‑ketoglutarate (CaAKG) dapat memperpanjang umur median betina hingga 16,6 % dan mengurangi kerentanan. Pada kelompok replikasi efeknya lebih kecil (10,5 %). Pada jantan tidak ada peningkatan yang signifikan secara statistik. Peneliti mengaitkan manfaat ini dengan penurunan peradangan sistemik dan kemungkinan peningkatan IL‑10, namun temuan ini masih terbatas pada tikus.
