摘要:The pursuit of materials with enhanced functionality has led to the emergence of metamaterials-artificially engineered materials whose properties are determined by their structure rather than composition. Traditionally, the building blocks of metamaterials are arranged in fixed positions within a lattice structure(1-19). However, recent research has revealed the potential of mixing disconnected building blocks in a fluidic medium(20-27). Inspired by these recent advances, here we show that by ...

摘要:The dual jaw joint of Morganucodon(1,2) consists of the dentary-squamosal joint laterally and the articular-quadrate one medially. The articular-quadrate joint and its associated post-dentary bones constitute the precursor of the mammalian middle ear. Fossils documenting the transition from such a precursor to the mammalian middle ear are poor, resulting in inconsistent interpretations of this hallmark apparatus in the earliest stage of mammaliaform evolution(1-5). Here we report mandibular mi...

摘要:In response to pathogen infection, gasdermin (GSDM) proteins form membrane pores that induce a host cell death process called pyroptosis(1-3). Studies of human and mouse GSDM pores have revealed the functions and architectures of assemblies comprising 24 to 33 protomers(4-9), but the mechanism and evolutionary origin of membrane targeting and GSDM pore formation remain unknown. Here we determine a structure of a bacterial GSDM (bGSDM) pore and define a conserved mechanism of pore assembly. Eng...

摘要:Distinct brain and behavioural states are associated with organized neural population dynamics that are thought to serve specific cognitive functions(1, 2-3). Memory replay events, for example, occur during synchronous population events called sharp-wave ripples in the hippocampus while mice are in an 'offline' behavioural state, enabling cognitive mechanisms such as memory consolidation and planning(4, 5, 6, 7, 8, 9, 10-11). But how does the brain re-engage with the external world during this...
