摘要:Mucosal- associated invariant T (MAIT) cells are unconventional T cells that mediate rapid antimicrobial immune responses to antigens derived from microbial riboflavin pathway metabolites presented by the evolutionarily conserved MR1 molecules. MAIT cells represent a large pre- expanded T cell subset in humans and are involved in both protective immunity and inflammatory immunopathology. However, what controls the functional heterogeneity of human MAIT cell responses is still largely unclear. ...

摘要:Arousal refers to changes in brain- body state underpinning motivated behavior but lacks a proper definition and taxonomy. Neuroscience and psychology textbooks offer surprisingly different views on what arousal is, from a global brain-wide modulation of neuronal activity to a multidimensional construct, with specific brain-body patterns tuned to a given situation. The huge number of scientific articles mentioning arousal (similar to 50,000) highlights the importance of the concept but also ex...

摘要:Biofilms are three- dimensional structures containing one or more bacterial species embedded in extracellular polymeric substances. Although most biofilms are stationary, Flavobacterium johnsoniae forms a motile spherical biofilm called a zorb, which is propelled by its base cells and contains a polysaccharide core. Here, we report the formation of spatially organized, motile, multispecies biofilms, designated co- zorbs, that are distinguished by a core-shell structure. F. johnsoniae forms zor...

摘要:Perception and action are inherently entangled: our world view is shaped by how we explore our environment through complex and variable self-motion. Even when fixating stable stimuli, our eyes undergo small, involuntary movements. Fixational eye movements (FEM) render a stable world jittery on our retinae, which can be expected to harm neural coding. Yet, empirical evidence suggests that FEM help rather than harm human perception of fine detail. Here, we elucidate this paradox by uncovering un...

摘要:Airborne insects generate a leading edge vortex when they flap their wings. This coherent vortex is a low-pressure region that enhances the lift of flapping wings compared to fixed wings. Insect wings are thin membranes strengthened by a system of veins that does not allow large wing deformations. Bat wings are thin compliant skin membranes stretched between their limbs, hand, and body that show larger deformations during flapping wing flight. This study examines the role of the leading edge v...

摘要:The large labor markets of big cities offer greater possibilities for workers to gain skills and experience through successively better employment opportunities. This experience effect contributes to the higher average wages that are found in big cities compared to the economy as a whole. Racial wage inequality is also higher in bigger cities than in the economy on average. We offer an explanation for this pattern, demonstrating that there is substantial racial inequality in the economic retur...

摘要:Free- electron radiation, such as Cherenkov radiation and transition radiation, can gen-erate light at arbitrary frequencies and is fundamental to diverse applications, ranging from electron microscopy, spectroscopy, lasers, to particle detectors. Generally, the fea-tures of free- electron radiation are stochastic when electrons interact with random media. Counterintuitively, here, we reveal a type of free- electron radiation that has both its inten-sity and directionality invariant to specifi...

摘要:Ginkgolides are secondary metabolites unique to Ginkgo biloba with the potential to prevent and treat cardiovascular and cerebrovascular diseases. Although the biosynthetic pathways of ginkgolides have been partly uncovered, the mechanism regulating their bio-synthesis is still largely unknown. Here, using multiomic and genetic analyses, we report the identification of a transcription factor, named ETHYLENE RESPONSE FACTOR ASSOCIATED WITH GINKGOLIDE BIOSYNTHESIS (GbEAG), as a critical regula-t...

摘要:The two- line hybrid rice system, a cutting- edge hybrid rice breeding technology, has greatly boosted global food security. In thermo- sensitive genic male sterile (TGMS) lines, the critical sterility- inducing temperature (CSIT; the temperature at which TGMS lines change from male fertile to complete male sterile) acts as a key threshold. We recently uncovered that thermo- sensitive genic male sterility 5 (tms5), a sterile locus presenting in over 95% of TGMS lines, leads to the overaccumula...
