封面图上展示的是火星耶泽罗陨石坑的色彩增强光学图像,由“毅力号”火星探测器的Mastcam-Z仪器拍摄于2021年4月18日。图片中前景的平顶山,俗称科迪亚克孤丘,绵延2.2千米,宽250米。它暴露出的古老的层状岩石,表明了河流三角洲沉积物逐渐堆积的过程,以及之后的洪水来袭。

Enhanced-color optical image of Jezero crater, Mars, taken by the Perseverance rover’s Mastcam-Z instrument on 18 April 2021. The foreground flat-topped hill, informally named Kodiak butte, is 2.2 kilometers distant and 250 meters wide. It exposes ancient layered rocks that indicate gradual deposition of sediments in a river delta, followed by floods.

封面图展示的是1只老虎石斑鱼(黑带平鲉)正在礁石群中游弋。老虎石斑鱼的寿命可长达116岁。通过对88个品种的基因组分析揭示出了石斑鱼寿命的遗传基础,寿命最短的石斑鱼(少鳍平鲉)为11年,寿命超长的糙眼岩鱼(阿留申平鲉)可存活超过200年。

A tiger rockfish (Sebastes nigrocinctus) nestled in a cluster of rocks. Tiger rockfish can live as long as 116 years. A genomic analysis of 88 species reveals the genetic underpinnings of rockfish life spans, which range from 11 years for the shortest-lived species (Sebastes minor) to >200 years for the ultra-long-lived rougheye rockfish (Sebastes aleutianus).

封面图展示的是木星大气层的光学图像,由“朱诺号”太空探测器拍摄。云顶的颜色因成分不同而不同,可能是水、氨和硫化氢铵的混合物。图中左下方的大型狭长风暴被称为“驳船”;在图中右上方可以看到一个更接近圆形的白色风暴。来自朱诺探测器的微波和引力场数据有限,尚无法探知这个气态巨星风暴的深度。

Optical image of Jupiter’s atmosphere, taken by the Juno spacecraft. The cloud top colors vary because of differing compositions, probably mixtures of water, ammonia, and ammonium hydrosulfide. The large elongated storm in the lower left is known as a barge; a more circular white storm is visible at the top right. Microwave and gravitational field data from Juno constrain the depths of the gas giant’s storms.

炎症是许多人类疾病的共同特征。此外,越来越明确的是,它也是许多核心生物过程的必要组成部分,包括新陈代谢、伤口愈合及神经发育等。本期特刊重点介绍了我们对炎症生物学的最新理解,特别是其在体内平衡、细胞死亡、器官间交叉效应和病毒感染中的作用。

Inflammation is a common feature of many human diseases. Moreover, it is becoming increasingly clear that it is also integral to a variety of core biological processes, including metabolism, wound healing, and neurological development. This special issue highlights recent advances in our understanding of inflammation biology, especially its role in homeostasis, cell death, interorgan cross-talk, and viral infection.
