The synthesis of nitrogen-containing molecules through carbon-nitrogen (C-N) bond formation is critical for the discovery and preparation of medicines, agrochemicals, and materials. Here, we report the direct insertion of a nitrogen atom in...
Upslope plant species shifts in Mesoamerican cloud forests driven by climate and land use change [0.03%]
气候和土地使用改变驱动的中美洲云林植物物种向高位转移

Global change drives biodiversity shifts worldwide, but these shifts are poorly understood in highly diverse tropical regions. In tropical mountains, plants are mostly expected to migrate upslope in response to warming. To assess this, we a...

Jesús Aguirre-Gutiérrez et al.
Understanding the capacity of forests to adapt to climate change is of pivotal importance for conservation science, yet this is still widely unknown. This knowledge gap is particularly acute in high-biodiversity tropical forests. Here, we e...
G-quadruplex-stalled eukaryotic replisome structure reveals helical inchworm DNA translocation [0.03%]
G-四链体停滞的真核复制体结构揭示了螺旋DNA转位机制

DNA G-quadruplexes (G4s) are non-B-form DNA secondary structures that threaten genome stability by impeding DNA replication. To elucidate how G4s induce replication fork arrest, we characterized fork collisions with preformed G4s in the par...

Birth of rodent with coat genetically modified to resemble the extinct species raises ethical and conservation concerns.
Macrophage peroxisomes guide alveolar regeneration and limit SARS-CoV-2 tissue sequelae [0.03%]
巨噬细胞过氧化物酶体指导肺泡再生并限制SARS-CoV-2组织结局
