封面插圖描繪的是人類大腦的左半球,其中彩色像素代表組成大腦的細胞類型。腦科學計劃細胞普查聯盟(BICCN)發表在《科學》《科學進展》(封面圖展示的是大腦右半球)和《科學轉化醫學》上的論文集報道了對成人和發育中大腦的細胞分析,揭示了人腦的遺傳組織。

封面照片拍攝于美國馬里蘭州中部,展示的是一只剛剛蛻皮的周期蟬,它經過地下17 年的蟄伏之后爬出地面,正在草葉上曬干翅膀,然后將與數十億其他蟬一起合鳴、交配和產卵。研究人員發現,在2021 年第10 代蟬群出現期間,許多鳥類改變了飲食習慣轉而捕食這種海量的食物資源,從而顯著改變了森林食物網的動態。
After 17 years underground,a r e c e n t l y m o l t e d p e r i o d i c a lcicada dries its wings in centralMaryland before joining withbillions of others to chorus, mate,and lay eggs. Researchers foundthat during the 2021 Brood Xemergence, many species of birdsaltered their diets to feed on thismassive resource pulse, markedlyaltering the dynamics of forestfood webs.

封面插圖展示的下丘腦是大腦深處的一個小結構,它與大腦其他大量區域相連,并不知疲倦地與它們相互作用。它負責控制并調節許多基本的身體功能,以確保有機體在不斷變化的環境中生存。
T h e h y p o t h a l a m u s i s asmall structure deep inside thebrain that is connected to a vastnumber of other brain regions andtirelessly interacts with them. Itcontrols and modulates many basicbodily functions to ensure thesurvival of the organism underconstantly changing circumstances.

封面圖展示的是肯尼亞洛伊薩巴荒野中的一只長頸羚,它正在進食木本植物。草食性動物是構建植被的關鍵力量,而植被是許多生態系統的基礎。雖然食草可以促進自然生態系統中的植物多樣性,但同時也會抑制正在恢復的退化生態系統中的植物豐富度和多樣性。加強管理食草動物可以提高在全球范圍內不斷增加的植被恢復工作成功率。
A g e r e n u k (L i t o c r a n i u swalleri ) browses on woody plantsin the Loisaba Wilderness, Kenya.Herbivory is a key force thatstructures the vegetation that isfoundational to many ecosystems.Whereas herbivory can foster plantdiversity in natural ecosystems, itcan suppress plant abundance anddiversity in degraded ecosystemsundergoing restoration. Managingherbivory can enhance the successof vegetation restoration efforts,which are increasing globally.
