  摘要：Methane emissions from solid waste may represent a substantial fraction of the global anthropogenic budget, but few comprehensive studies exist to assess inventory assumptions. We quantified emissions at hundreds of large landfills across 18 states in the United States between 2016 and 2022 using airborne imaging spectrometers. Spanning 20% of open United States landfills, this represents the most systematic measurement-based study of methane point sources of the waste sector. We detected sign...

  摘要：Surveillance of mitotic timing prevents amplification of damaged cells Mitosis is a challenging time for cells owing to the potential for structural and numerical chromosomal abnormalities, termed chromosomal instability, which is a hallmark of cancer (1). In M phase, chromosomal instability is prevented by the spindle assembly checkpoint, which delays cell cycle progression until chromosomes are properly attached to spindle microtubules, ensuring proper separation into daughter cells (2). Rec...
