  摘要：Efficient nitrogen assimilation is important for sustainable agriculture1, yet its subcellular organization remains unknown. Here we show that plastoglobules (PGs) in the chloroplasts of mesophyll cells function as a metabolic hub that orchestrates nitrogen utilization in maize. Nitrogen-responsive dynamics of PGs represent a conserved feature across plant species. We identify two key enzymes, nitrite reductase 2 (ZmNIR2) and glutamine synthetase 1 (ZmGLN1), specifically targeted to PGs by a c...

  摘要：Seagrass ecosystems underpin coastal biodiversity1 and provide vital ecosystem services, including shoreline protection2, food security3 and climate mitigation4. Despite growing recognition as a nature-based climate solution, seagrasses are among the least mapped and most poorly understood vegetated coastal ecosystems5. Here we present, to our knowledge, the first global 10-m spatial resolution maps and change analysis of seagrass extent in clear, shallow coastal waters, derived from 4.75 mill...

  摘要：Homologous recombination (HR) deficiency increases sensitivity to DNA-damaging agents that are commonly used to treat cancer1. In HR-proficient cancers, the metabolic mechanisms that drive response or resistance to DNA-damaging agents remain unclear. Here we have identified that depletion of alpha-ketoglutarate (alpha KG) sensitizes HR-proficient cells to DNA-damaging agents by metabolic regulation of histone acetylation. alpha KG is required for the activity of alpha KG-dependent dioxygenases...
• Universal gates from braiding and fusing anyons on quantum hardware AI翻译

  摘要：A quantum computer requires the ability to store and manipulate information globally to protect against local noise. Topologically ordered phases1,2 offer two routes: encoding information in the ground-state subspace3 or in anyonic excitations1,4,5. The toric code1 exemplifies the first approach but does not intrinsically support a universal gate set. The latter-topological quantum computation-implements gates by braiding non-Abelian anyons6 around each other. However, the simplest non-Abelian...
• Verification of the Outer Space Treaty with cosmic protons AI翻译

  摘要：The Outer Space Treaty (OST) was opened to signatures in 1967 and, since then, 117 countries, including China, the USA and Russia, have become part of it1. Among other stipulations, the treaty bans the placement of nuclear weapons in outer space. Recently, the US government has raised worries that Russia is testing nuclear-armed anti-satellite weapon (ASAT) components, with the possibility that it will place a nuclear weapon in space. Such a device, if detonated, would destroy most of the sate...
