摘要：Crop yield potential is constrained by the inherent trade-offs among traits such as between grain size and number. Brassinosteroids (BRs) promote grain size, yet their role in regulating grain number is unclear. By deciphering the clustered-spikelet rice germplasm, we show that activation of the BR catabolic gene BRASSINOSTEROID-DEFICIENT DWARF3 (BRD3) markedly increases grain number. We establish a molecular pathway in which the BR signaling inhibitor GSK3/SHAGGY-LIKE KINASE2 phosphorylates a...

摘要：The idea of guidance toward a target is central to axon pathfinding and brain wiring in general. In this work, we show how several thousand axonal growth cones self-pattern without target-dependent guidance during neural superposition wiring in Drosophila. Ablation of all target lamina neurons or loss of target adhesion prevents the stabilization but not the development of the pattern. Intravital imaging at the spatiotemporal resolution of growth cone dynamics in intact pupae and data-driven d...

摘要：Adaptive optics (AO) has revolutionized imaging in fields from astronomy to microscopy by correcting optical aberrations. In label-free microscopes, however, conventional AO faces limitations because of the absence of a guide star and the need to select an optimization metric specific to the sample and imaging process. Here, we propose an AO approach leveraging correlations between entangled photons to directly correct the point spread function. This guide star-free method is independent of th...

摘要：Vocalizations play a pivotal role in communication across species. Although the complexity of articulation varies, the basic process of sound production for the tonal component in mammals involves narrowing of the larynx (vocal cord adduction)-located between the trachea and pharynx-and exhalation. There is an intricate interplay between phonation and respiration to ensure that breathing is not affected. As a result, vocal utterances are properly aligned and embedded within respiratory cycles,...

摘要：High-Qmicroresonators are indispensable components of photonic integrated circuits and offerseveral useful operational modes. However, these modes cannot be reconfigured after fabricationbecause they are fixed by the resonator's physical geometry. In this work, we propose a Moir & eacute; speedupdispersion tuning method that enables a microresonator device to operate in any of three modes.Electrical tuning of Vernier coupled rings switches operating modality to Brillouin laser, brightmicrocomb...
