Twisted atomic layers slide spontaneously at room temperature in simulations
Researchers revealed an ultralow-barrier collective sliding mechanism mediated by domain walls, as well as defect-induced pinning of the sliding motion. They found that twisted bilayer MoS₂ moiré superlattices can undergo spontaneous long-range interlayer sliding at room temperat

Climate shapes microbial nitrogen pump in forests, not in farmlands
Microbes build a long-lived nitrogen reservoir in soil from the remains of dead bacteria and fungi, which cling to minerals and resist decay. The microbial nitrogen pump turns nitrogen taken up by living microbes into this persistent pool, and microbial nitrogen use efficiency (N
