Neuromorphic vision sensors capable of multispectral perception and efficient recognition are highly desirable for bioretina emulation, but their realization is challenging. Here, we present a cocrystal strategy for preparing an organic nanowire retinamorphic vision sensor with UV-vis-NIR perception and fast recognition. By leveraging molecular-scale donor-acceptor interpenetration and charge-transfer interfaces, the cocrystal nanowire device exhibits ultrawide photoperception ranging from 350 to 1050 nm, fast photoresponse of 150 ms, high specific detectivity of 8.

Modular chemical postmodification of peptides is a promising strategy that supports the optimization and innovation of hit peptide therapeutics by enabling rapid derivatization. However, current methods are primarily limited to traditional bio-orthogonal strategies and chemical ligation techniques, which require the preintroduction of non-natural amino acids and impose fixed methods that limit peptide diversity. Here, we developed the Tyrosine-1,2,3-Triazine Ligation (YTL) strategy, which constructs novel linkages (pyridine and pyrimidine) through a "one-pot, two-step" process combining SAr and IEDDA reactions, promoting modular post modification of Tyr-containing peptides.

Osteosarcoma (OS) is a commonly observed malignant tumor in orthopedics that has a very poor prognosis. The endosomal sorting complex required for transport (ESCRT) is important for the development and progression of cancer and may be a significant target for cancer therapy. First, we built a prognostic signature using 7 ESCRT-related genes (ERGs) to predict OS patient prognosis.

Induced by a sharp-tip-enhanced electric field, periodical nanoassemblies can regulate the reactant flux on the electrode surface, efficiently optimizing the mass transfer kinetics in electrocatalysis. However, when the nanoscale building blocks in homoassemblies are arranged densely, it results in the overlap and reduction of the local electric field. Herein, we present a comprehensive kinetic heteromodel that simultaneously couples the sharp-tip-enhanced electric field and charge transfer electric field between different building blocks with any arrangement densities.

Androgens, such as 5α-dihydrotestosterone (5α-DHT), regulate numerous functions by binding to nuclear androgen receptors (ARs) and potential unknown membrane receptors. Here, we report that the androgen 5α-DHT activates membrane receptor GPR133 in muscle cells, thereby increasing intracellular cyclic AMP (cAMP) levels and enhancing muscle strength. Further cryoelectron microscopy (cryo-EM) structural analysis of GPR133-Gs in complex with 5α-DHT or its derivative methenolone (MET) reveals the structural basis for androgen recognition.
