• Why repairing forests is not just about planting trees AI翻译

  摘要：An exploration of deforestation and restoration shows that woods are much more than trees. They depend on - and provide for - people, animals and microbes.

  摘要：Majorana zero modes (MZMs) are emergent zero-energy topological quasiparticles that are their own antiparticles(1,2). Detected MZMs are spatially separated and electrically neutral, so producing hybridization between MZMs is extremely challenging in superconductors(3,4). Here, we report the magnetic field response of vortex bound states in superconducting topological crystalline insulator SnTe (001) films. Several MZMs were predicted to coexist in a single vortex due to magnetic mirror symmetr...

  摘要：Conservation, restoration and land management are increasingly implemented at landscape scales(1,2). However, because species interaction data are typically habitat- and/or guild-specific, exactly how those interactions connect habitats and affect the stability and function of communities at landscape scales remains poorly understood. We combine multi-guild species interaction data (plant-pollinator and three plant-herbivore-parasitoid communities, collected from landscapes with one, two or th...

  摘要：The canonical theory for planet formation in circumstellar disks proposes that planets are grown from initially much smaller seeds(1-5). The long-considered alternative theory proposes that giant protoplanets can be formed directly from collapsing fragments of vast spiral arms(6-11) induced by gravitational instability(12-14)-if the disk is gravitationally unstable. For this to be possible, the disk must be massive compared with the central star: a disk-to-star mass ratio of 1:10 is widely hel...

  摘要：Crustal accretion at mid-ocean ridges governs the creation and evolution of the oceanic lithosphere. Generally accepted models(1-4) of passive mantle upwelling and melting predict notably decreased crustal thickness at a spreading rate of less than 20mmyear(-1). We conducted the first, to our knowledge, high-resolution ocean-bottom seismometer (OBS) experiment at the Gakkel Ridge in the Arctic Ocean and imaged the crustal structure of the slowest-spreading ridge on the Earth. Unexpectedly, we ...

  摘要：Coronaviruses remodel the intracellular host membranes during replication, forming double-membrane vesicles (DMVs) to accommodate viral RNA synthesis and modifications(1,2). SARS-CoV-2 non-structural protein 3 (nsp3) and nsp4 are the minimal viral components required to induce DMV formation and to form a double-membrane-spanning pore, essential for the transport of newly synthesized viral RNAs3-5. The mechanism of DMV pore complex formation remains unknown. Here we describe the molecular archi...
