The cover feature picture shows the importance of zinc in altering lipid composition in cellular membranes, which affects signal transduction inside the brain. Mass spectrometry imaging was used to show that zinc deficiency changes lipid composition and lipid abundance in the brain of Drosophila and the changes are similar to those caused by cognitive‐impairing drugs. More information can be found in the communication by A. G. Ewing et al.

锌缺乏导致果蝇大脑中脂质的变化，类似于认知障碍药物：成像质谱研究

封面特征图片显示了锌在改变细胞膜中脂质成分的重要性，锌会影响大脑内部的信号传导。质谱成像显示锌缺乏会改变果蝇大脑中的脂质组成和脂质丰度，其变化与认知障碍药物引起的变化相似。可以在A. G. Ewing等人的来文中找到更多信息。
