В рамках нашей рубрики «Картинка дня» мы продолжаем знакомить вас с победителями конкурса Nikon Small World. Среди работ, удостоенных почетного упоминания жюри (Honorable Mention) — вот эта прекрасная фоторабота, на которой мы видим сосуд головного мозга, окруженный астроцитами в тонком срезе головного мозга человека.
