Approach: conceptual metaphor. Palette: D, bold color field.

A single AA-style cylindrical battery stands upright, fully charged, on a seamless saturated mustard-yellow backdrop. Beside it sits a matching, untouched, slightly dusty glass jar of marbles, so the charge shows no visible link to any result. More precisely, a bright tomato-red extension cord plugs into the battery's top. Its other end curls away unconnected, lying on the floor beside an unlit incandescent bulb. A small electric green LED glows on the battery's side as the only green accent. Camera: low three-quarter angle, 50mm lens, shallow depth of field, with the bulb softly blurred in the foreground. Lighting: hard, clean studio key light from the upper left, with crisp shadows falling to the right on the yellow surface. Mood: puzzled, wry, a full power source that fails to light anything.

烟酰胺核苷令 NAD+ 翻倍,却未改善记忆

BY NOVA CHEN ·

一种补充剂让血液中的关键分子水平翻了一番,但记忆没有任何改善。12 周的随机对照试验在轻度认知障碍(aMCI)老年人中进行,结果显示烟酰胺核苷(NR)将 NAD+ 提高了两倍,却未带来认知、整体脑血流或血压的变化。唯一稍显兴趣的是探索性分析中出现的海马区血流增高提示,但这远不足以构成证据。下面我们来看看这项研究到底说明了什么、存在哪些局限,以及如果你正考虑购买 NAD+ 提升剂该如何看待。

Approach: macro science, a lithium-themed image built around the actual metal and tissue. Palette: bold color field in saturated teal.

Extreme close-up photograph of a single freshly cut piece of silvery lithium metal, its surface partly tarnishing to grey and matte black at the edges, resting on a thin slice of translucent brain tissue on a glass microscope slide. The slice shows fine pink-grey folds and a few dark clumped plaque-like specks. The backdrop is a smooth saturated teal field, with the slide placed diagonally. Shallow depth of field keeps the metal edge razor sharp while the tissue softens toward the corners. Lighting is a crisp, slightly warm side light from the left, with a small specular highlight on the metal and a soft shadow on the teal. A tiny electric green reflection glints in the glass edge. The mood is quiet, investigative and precise. Shot from a low 30-degree angle, with no text or labels.

阿尔茨海默症发作前,大脑中缺失的微量矿物

BY DR. SYNAPSE ·

哈佛大学在《Nature》上发表的里程碑式研究发现,锂是轻度认知障碍(MCI)患者大脑中唯一明显缺失的金属。小鼠实验显示,脑内锂含量下降约 50% 会导致淀粉样蛋白沉积、tau 病理、炎症以及记忆衰退,而低剂量的锂鸟氨酸(Lithium Orotate)能够阻止这些改变。该化合物似乎能够躲避淀粉样斑块对普通锂盐的捕获。不过,目前仅有动物实验数据,尚缺乏人体临床验证,同时锂的长期使用也可能带来肾脏、甲状腺及药物相互作用等风险。以下将详细阐述研究发现、未证实的内容以及未来值得关注的方向。
