Summary: Fluorescent probes are valuable tools for visualizing plasma membranes and their related physiological processes in a spatiotemporal manner. However, there is a lack of probes for long-term imaging of plant cell membranes. In this study, we designed an AIE-active probe with NIR emission that allows for four-dimensional spatiotemporal imaging of plant cell membranes. The probe showed excellent specificity and long imaging times, making it a valuable tool for monitoring dynamic processes of plasma membrane-related events.

Summary: Long-term tracking is a critical and rapidly developing field in visual object tracking research. In this paper, a Hierarchical Memoryguided Long-term Tracker (HMLT) with a Meta Transformer Inquiry Network (MTIN) is proposed to improve online learning. The method introduces a hierarchical memory strategy that simplifies and reliably updates long-term tracking components using multiple target memories. Our experimental results demonstrate that the proposed method achieves comparable performance to the state-of-the-art long-term tracking algorithms.

Summary: Several long-period radio transients have been discovered, including the recent observation of a 21-minute radio transient named GPM J1839-10. These events are characterized by strongly polarized coherent radio pulses with varying brightness and quasiperiodic substructure. The origin and mechanisms of these transients, particularly the slowly rotating neutron stars, are still debated among scientists. The discovery provides new insights for understanding dipolar radio emission from isolated neutron stars.

Summary: This paper proposes a novel, robust, and real-time long-term tracking framework based on the local search module and re-detection module. The local search module includes an effective bounding box regressor and a target verifier, which can generate a series of candidate proposals and infer the optimal candidate with its confidence score. For local search, a long short-term updated scheme is designed to improve the target verifier. In terms of global re-detection, a novel re-detection module is developed to estimate the target position and target size for a given base tracker.

Summary: Photodynamic therapy is a popular method for combating bacteria. In this study, researchers have developed an aggregating-induced-emission-active bacterial inhibitor and photosensitizer called OTM, which can efficiently bind to and kill Gram-positive bacteria. OTM is also an efficient photosensitizer that enhances the production of reactive oxygen species, thereby increasing its killing effect on both Gram-positive and Gram-negative bacteria. Additionally, OTM exhibits excellent biocompatibility with normal mammalian cells and can promote the healing of bacteria-infected wounds in mice models without affecting their organs and blood parameters, making it a promising candidate for clinical applications.
