摘要:A cutting-edge global model of the atmosphere combines machine learning with a numerical model based on the laws of physics. This 'hybrid' system accurately predicts the weather - and even shows promise for climate simulations.

摘要:Even though geologists have rejected the designation of an Anthropocene epoch, the idea of a major planetary transition in the mid-twentieth century remains useful across physical and social sciences, the humanities and policy.

摘要:During development, motor neurons originating in the brainstem and spinal cord form elaborate synapses with skeletal muscle fibres(1). These neurons release acetylcholine (ACh), which binds to nicotinic ACh receptors (AChRs) on the muscle, initiating contraction. Two types of AChR are present in developing muscle cells, and their differential expression serves as a hallmark of neuromuscular synapse maturation(2-4). The structural principles underlying the switch from fetal to adult muscle rece...

摘要:Antiferromagnetic spintronics(1,2) shows great potential for high-density and ultrafast information devices. Magnetic tunnel junctions (MTJs), a key spintronic memory component that are typically formed from ferromagnetic materials, have seen rapid developments very recently using antiferromagnetic materials(3,4). Here we demonstrate a twisting strategy for constructing all-antiferromagnetic tunnel junctions down to the atomic limit. By twisting two bilayers of CrSBr, a 2D antiferromagnet (AFM...

摘要:The nucleus of almost all massive galaxies contains a supermassive black hole (BH)(1). The feedback from the accretion of these BHs is often considered to have crucial roles in establishing the quiescence of massive galaxies(2-14), although some recent studies show that even galaxies hosting the most active BHs do not exhibit a reduction in their molecular gas reservoirs or star formation rates(15-17). Therefore, the influence of BHs on galaxy star formation remains highly debated and lacks di...

摘要:Methane is the second most abundant climate-active gas, and understanding its sources and sinks is an important endeavour in microbiology, biogeochemistry, and climate sciences(1,2). For decades, it was thought that methanogenesis, the ability to conserve energy coupled to methane production, was taxonomically restricted to a metabolically specialized group of archaea, the Euryarchaeota(1). The discovery of marker genes for anaerobic alkane cycling in metagenome-assembled genomes obtained from...
