  摘要：Plants can move rapidly without muscles, as seen in the Venus flytrap's snapping lobes-a long-standing puzzle in plant biomechanics. Trap closure involves an elastic instability, but the active mechanical driver has remained elusive. Using in situ hydraulic and mechanical measurements, we identified the motor driving this transition. Closure occurs too quickly to be explained by water transport, revealing a distinct, nonhydraulic mechanism: a rapid (about one second) softening of the epidermal...

  摘要：The transformation of the Roman world [fourth to ninth centuries common era (CE)], culminating in the Western Roman Empire's fall, marked a fundamental transition in European history. Key questions persist regarding the regionally specific nature of this transformation. We generated a paleogenomic dataset to reconstruct post-Roman organizations in the Little Hungarian Plain at microregional resolution. Genetic and archaeological analyses of two Roman (n = 68) and five post-Roman (n = 246) site...
