  摘要：Unconventional quasiparticles emerging in the fractional quantum Hall regime(1,2) present the challenge of observing their exotic properties unambiguously. Although the fractional charge of quasiparticles has been demonstrated for nearly three decades(3-5), the first convincing evidence of their anyonic quantum statistics has only recently been obtained(6,7) and, so far, the so-called scaling dimension that determines the propagation dynamics of the quasiparticles remains elusive. In particula...
• y Are the Cosmic Gems the earliest star clusters ever detected? AI翻译

  作者单位：Wellesley College
  摘要：Observations might have uncovered star clusters that existed when the Universe was just 460 million years old. If this timing is accurate, the discovery provides valuable clues about how and when the first stars formed.

  摘要：The carbon skeleton of any organic molecule serves as the foundation for its three-dimensional structure, playing a pivotal role in determining its physical and biological properties(1). As such, taxane diterpenes are one of the most well-known natural product families, primarily owing to the success of their most prominent compound, paclitaxel, an effective anticancer therapeutic for more than 25years(2-6). In contrast to classical taxanes, the bioactivity of cyclotaxanes (also referred to as...
• US postdoc support from NIH could be capped at five years - sparking criticism AI翻译
  作者：Kozlov, Max
  摘要：A working group's recommendation, meant to help to advance the careers of postdoctoral researchers, could discourage people from staying in academia, some researchers say.

  摘要：A broad range of brain pathologies critically relies on the vasculature, and cerebrovascular disease is a leading cause of death worldwide. However, the cellular and molecular architecture of the human brain vasculature remains incompletely understood(1). Here we performed single-cell RNA sequencing analysis of 606,380 freshly isolated endothelial cells, perivascular cells and other tissue-derived cells from 117 samples, from 68 human fetuses and adult patients to construct a molecular atlas o...

  摘要：Understanding the provenance of megaliths used in the Neolithic stone circle at Stonehenge, southern England, gives insight into the culture and connectivity of prehistoric Britain. The source of the Altar Stone, the central recumbent sandstone megalith, has remained unknown, with recent work discounting an Anglo-Welsh Basin origin(1,2). Here we present the age and chemistry of detrital zircon, apatite and rutile grains from within fragments of the Altar Stone. The detrital zircon load largely...
