  摘要：Sexual reproduction relies on meiotic chromosome pairing to form bivalents, a process that is complicated in polyploids owing to the presence of multiple subgenomes1. Uneven ploidy mostly results in sterility due to unbalanced chromosome pairing and segregation during meiosis. However, pentaploid dogroses (Rosa sect. Caninae; 2n = 5x = 35) achieve stable sexual reproduction through a unique mechanism: 14 chromosomes form bivalents and are transmitted biparentally, while the remaining 21 chromo...

  摘要：Mirroring the complex structures and diverse functions of natural organisms is a long-standing challenge in robotics1, 2, 3-4. Modern fabrication techniques have greatly expanded the feasible hardware5, 6, 7-8, but using these systems requires control software to translate the desired motions into actuator commands. Conventional robots can easily be modelled as rigid links connected by joints, but it remains an open challenge to model and control biologically inspired robots that are often sof...

  摘要：Metal halide perovskites are promising materials for light-emitting diodes (LEDs)1, 2, 3-4. Spatially confining charge carriers using nanocrystal/quantum dots5, 6, 7, 8-9, low-dimensional perovskites10, 11, 12-13 and ultrathin perovskite layers14 have all been used to improve the external quantum efficiency of perovskite LEDs (PeLEDs). However, most strongly space-confined perovskites suffer from severe Auger recombination, ion migration and thermal instability, resulting in limited brightness...
