封面插图描绘的是人类大脑的左半球，其中彩色像素代表组成大脑的细胞类型。脑科学计划细胞普查联盟（BICCN）发表在《科学》《科学进展》（封面图展示的是大脑右半球）和《科学转化医学》上的论文集报道了对成人和发育中大脑的细胞分析，揭示了人脑的遗传组织。

This illustration depicts the left hemisphere of the human brain, with colored pixels representing the cell types composing the brain. Cellular analysis of the adult and developing brain is reported in a collection of papers from the BICCN consortium published in Science, Science Advances [with the cover showing the brain’s right hemisphere], and Science Translational Medicine. The results uncover the genetic organization of the human brain.

封面照片拍摄于美国马里兰州中部，展示的是一只刚刚蜕皮的周期蝉，它经过地下17年的蛰伏之后爬出地面，正在草叶上晒干翅膀，然后将与数十亿其他蝉一起合鸣、交配和产卵。研究人员发现，在2021年第10代蝉群出现期间，许多鸟类改变了饮食习惯转而捕食这种海量的食物资源，从而显著改变了森林食物网的动态。

After 17 years underground, a recently molted periodical cicada dries its wings in central Maryland before joining with billions of others to chorus, mate, and lay eggs. Researchers found that during the 2021 Brood X emergence, many species of birds altered their diets to feed on this massive resource pulse, markedly altering the dynamics of forest food webs.

封面插图展示的下丘脑是大脑深处的一个小结构，它与大脑其他大量区域相连，并不知疲倦地与它们相互作用。它负责控制并调节许多基本的身体功能，以确保有机体在不断变化的环境中生存。

The hypothalamus is a small structure deep inside the brain that is connected to a vast number of other brain regions and tirelessly interacts with them. It controls and modulates many basic bodily functions to ensure the survival of the organism under constantly changing circumstances.

封面图展示的是肯尼亚洛伊萨巴荒野中的一只长颈羚，它正在进食木本植物。草食性动物是构建植被的关键力量，而植被是许多生态系统的基础。虽然食草可以促进自然生态系统中的植物多样性，但同时也会抑制正在恢复的退化生态系统中的植物丰富度和多样性。加强管理食草动物可以提高在全球范围内不断增加的植被恢复工作成功率。

A gerenuk (Litocranius walleri) browses on woody plants in the Loisaba Wilderness, Kenya. Herbivory is a key force that structures the vegetation that is foundational to many ecosystems. Whereas herbivory can foster plant diversity in natural ecosystems, it can suppress plant abundance and diversity in degraded ecosystems undergoing restoration. Managing herbivory can enhance the success of vegetation restoration efforts, which are increasing globally.
