摘要:Why birds sing intensely in a dawn chorus during the early morning has long been debated. Evidence gathered from observing birds in the wild offers a fresh perspective on what might drive this phenomenon.

摘要:Precise control of cell division is essential for proper patterning and growth during the development of multicellular organisms. Coordination of formative divisions that generate new tissue patterns with proliferative divisions that promote growth is poorly understood. SHORTROOT (SHR) and SCARECROW (SCR) are transcription factors that are required for formative divisions in the stem cell niche of Arabidopsis roots(1,2). Here we show that levels of SHR and SCR early in the cell cycle determine...

摘要:Early embryonic development in humans remains poorly understood. A 3D cellular model called bilaminoids, generated using 'naive' pluripotent stem cells and derived cell types, successfully recapitulates early development and enables mechanistic studies to examine how various cellular components interact to regulate early embryogenesis.

摘要:The wealth of complex polar topologies(1-10) recently found in nanoscale ferroelectrics results from a delicate balance between the intrinsic tendency of the materials to develop a homogeneous polarization and the electric and mechanical boundary conditions imposed on them. Ferroelectric-dielectric interfaces are model systems in which polarization curling originates from open circuit-like electric boundary conditions, to avoid the build-up of polarization charges through the formation of flux...

摘要:Spatial, momentum and energy separation of electronic spins in condensed-matter systems guides the development of new devices in which spin-polarized current is generated and manipulated(1-3). Recent attention on a set of previously overlooked symmetry operations in magnetic materials(4) leads to the emergence of a new type of spin splitting, enabling giant and momentum-dependent spin polarization of energy bands on selected antiferromagnets(5-10). Despite the ever-growing theoretical predicti...
