CRISPR–Cas regulates expression of embedded anti-phage defence systems

Nature, Published online: 22 July 2026; doi:10.1038/s41586-026-10833-9

CRISPR–Cas systems transcriptionally tune diverse innate defences using CRISPR RNA-like guides to balance antiviral protection with fitness, and hyperactivate these defences when compromised, establishing a layered bacterial ‘immunity guard’ network.

Structural basis of the RNA-editing cascade in trypanosome mitochondria

Nature, Published online: 22 July 2026; doi:10.1038/s41586-026-10831-x

Cryo-electron microscopy sheds light on the architecture of the Trypanosoma brucei mitochondrial editosome and reveals how this assembly mediates mRNA editing through the insertion and deletion of uridine nucleotides.

Scalable quasi-pure MOF membranes for energy-efficient gas separations

Nature, Published online: 15 July 2026; doi:10.1038/s41586-026-10655-9

Scalable quasi-pure metal–organic framework membranes achieve near-intrinsic separation performance, enabling energy-efficient industrial gas separations with major cost reductions compared with distillation.

Controlled solid-state crystallization with formamidinium acetate for fully vacuum-deposited perovskite solar cells

Nature Energy, Published online: 14 July 2026; doi:10.1038/s41560-026-02093-8

Vacuum-processed perovskite solar cells show promise, yet their efficiency remains limited. Xu et al. use formamidinium acetate to promote perovskite crystallization, achieving a 25.5% power conversion efficiency and 1,000 h operational stability.

Tin perovskite transistors stabilized through volatile coordination

Nature, Published online: 01 July 2026; doi:10.1038/s41586-026-10714-1

A volatile-assisted coordination strategy regulates surface defect chemistry and self-doping, thus stabilizing the stoichiometry of tin perovskite semiconductors, resulting in transistors that can maintain stable operation for a month at temperatures of 100 °C.

A thalamus–brainstem attractor network drives history-biased decisions

Nature, Published online: 10 June 2026; doi:10.1038/s41586-026-10623-3

Whole-brain, cellular-resolution imaging reveals a hierarchical thalamus–brainstem attractor network that encodes recent history and shapes behavioural bias in zebrafish.

Highly stable Mn–Sn flow batteries towards low-temperature energy storage

Energy Environ. Sci., 2026, 19,3924-3933
DOI: 10.1039/D6EE01772J, Paper
Yu Shu, Yexuan Yu, Hongjie Xiao, Ziyi Xiang, Liping Wan, Guodong Li, Yao Liu, Jianhang Huang, Yonggang Wang
An acidic Mn–Sn flow battery was developed to overcome low-temperature limitations, enabling operation at an unprecedented temperature of −45 °C, which exhibits a high energy efficiency of up to 85% and energy density of 48 Wh L−1.
