This reaction enables deep chemical surveys of reactive proteins and covalent tracking of intracellular viral and bacterial pathogens.

Plants utilize anion channels to adapt to environmental stresses. Here, authors elucidate the coordinated regulatory mechanisms within the SLAH family and demonstrate that tRNA molecules directly bind to and inhibit the SLAH1 anion channel.

A library preparation method using anchored random reverse primer sequencing for quantitative analysis of novel gene fusions from low-input samples.

METTL3 promotes healthy placenta function by regulating m⁶A methylation and histone epigenetics. Deficiency in METTL3 leads to premature senescence, inflammation activation of trophoblasts, contributing to pregnancy complications like preeclampsia.

Here, the authors show that a human gut fungus, Clavispora lusitaniae P4013B, alleviates colitis in mice through the activation of the aryl hydrocarbon receptor, in turn mediated by its metabolite indole-3ethanol, indicating its potential as a probiotic for inflammatory bowel disease.

This work proposed a fully heterogeneous quantum network that connects diverse user systems and enables multiple quantum tasks. A software-defined quantum network structure is also proposed for coordinating network nodes and optimizing network performance. It paves the way for an open and versatile quantum internet.
