  摘要：Although momentum is building to restore bison across North America, most efforts focus on small, managed herds, leaving unclear how large, migrating herds shape landscapes and whether their effects enhance or degrade ecosystems. We assessed carbon and nitrogen dynamics across the northern Yellowstone ecosystem, where one of the last remaining large migratory populations resides. Bison stabilized net aboveground production while accelerating nitrogen turnover, increasing aboveground nitrogen p...

  摘要：Classical and quantum technologies have traditionally been viewed as orthogonal, with classical systems being deterministic and quantum systems inherently probabilistic. This distinction hinders the development of a scalable quantum internet even as the global internet continues expanding. We report a classical-decisive quantum internet architecture in which the integration of quantum information into advanced photonic technologies enables efficient entanglement distribution over a commerciall...
• The rise of rideable horses Early horse riders selected a rare mutation in a single gene to enhance rideability AI翻译

  摘要：Although horses have played a transformative role in the recent evolution of humans, altering communication, transportation, farming, and warfare, their domestication occurred unexpectedly late, only around 4500 years ago-more than 5000 years after the domestication of pigs, goats, cattle, and sheep. On page 925 of this issue, Liu et al. (1) report using a combination of ancient DNA analysis and experimental work with mouse models to provide new evidence of the biological changes that transfor...

  摘要：Tissue macrophages reside in anatomically distinct subtissular niches that shape their identity and function. In white adipose tissue (WAT), we identified three macrophage populations with distinct localization, turnover, and phenotypes. Septal adipose tissue macrophages (sATMs), marked by CD209b and lymphatic vessel endothelial hyaluronan receptor 1, were long-lived and positioned in close proximity to adipocyte stem cells (ASCs) within the WAT septum. Within this shared niche, sATMs instruct...

  摘要：Transfer RNA-derived small RNAs (tsRNAs or tDRs) perform a range of cellular functions. Here, we showed that tRNA-Asp-GTC-3 ' tDR, a hypoxia-induced tDR derived from the 3 ' end of tRNA-Asp-GTC, activated autophagic flux in kidney cells and its silencing blocked autophagic flux. Functional gain-/loss-of-function studies in murine kidney disease models demonstrated a substantial renoprotective function of tRNA-Asp-GTC-3 ' tDR. Mechanistically, tRNA-Asp-GTC-3 ' tDR assembled stable G-quadruplex ...

  摘要：Determining the atomic structure of nanoparticles (NPs) is critical for understanding their structural evolution and properties. However, controlling the growth of multiply-twinned metal NPs remains challenging because of numerous competing pathways. In this work, we report the synthesis of two giant silver icosahedral nanoclusters, [Ag213(C equivalent to CR1)96]5- and [Ag429Cl24(C equivalent to CR2)150]5- (Ag213 and Ag429, R1 =3,4,5-F3C6H2 and R2 = 4-CF3C6H4), achieved through ligand engineer...
