  摘要：Telomerase is intimately associated with stem cells and cancer, because it catalytically elongates telomeres-nucleoprotein caps that protect chromosome ends(1). Overexpression of telomerase reverse transcriptase (TERT) enhances the proliferation of cells in a telomere-independent manner(2-8), but so far, loss-of-function studies have provided no evidence that TERT has a direct role in stem cell function. In many tissues, homeostasis is shaped by stem cell competition, a process in which stem c...

• How does the spliceosome dismantle itself? AI翻译
  作者：Shi, Shasha; Zhao, Rui
  作者单位：University of Colorado System; University of Colorado Anschutz Medical Campus
  摘要：Precursor messenger RNA is edited into its final form by an RNA-protein assembly called the spliceosome. Structural evidence provides insights into how the spliceosome is disassembled when its job is complete.
• Carbon pricing reduces emissions AI翻译
  作者：Sterner, Thomas
  作者单位：University of Gothenburg
  摘要：A meta-analysis of 21 carbon-pricing schemes suggests that the strategy reduces greenhouse-gas emissions. Deciding how high to set prices is the next step - and one that might benefit from the insights of less-aggregated studies in various sectors.

  摘要：Chiral superconductors, a unique class of unconventional superconductors in which the complex superconducting order parameter winds clockwise or anticlockwise in the momentum space(1), represent a topologically non-trivial system with intrinsic time-reversal symmetry breaking (TRSB) and direct implications for topological quantum computing(2,3). Intrinsic chiral superconductors are extremely rare, with only a few arguable examples, including UTe2, UPt3 and Sr2RuO4 (refs. 4-7). It has been sugg...

  摘要：Reducing carbon dioxide (CO2) emissions urgently requires the large-scale deployment of carbon-capture technologies. These technologies must separate CO2 from various sources and deliver it to different sinks(1,2). The quest for optimal solutions for specific source-sink pairs is a complex, multi-objective challenge involving multiple stakeholders and depends on social, economic and regional contexts. Currently, research follows a sequential approach: chemists focus on materials design(3) and ...
