Fluorescence imaging of subcellular structures is crucial for understanding cellular functions and disease mechanisms. However, existing fluorescent dyes are plagued by inadequate biocompatibility and insufficient stability, which impede the advancement of high-resolution, long-term, and live-cell imaging. In this work, we innovatively synthesized a novel nickel nanocluster encapsulated with ficin (Ficin-Ni NCs) through a straightforward biomineralization approach as a fluorescent probe for imaging the nucleus. The Ficin-Ni NCs with intense green fluorescence exhibited a particle size of approximately 1.56 nm, significant Stokes shift (110 nm), and remarkable stability (98 % fluorescence intensity after 14 days). Meanwhile, the Ni NCs demonstrated excellent biocompatibility, maintaining cell viability above 90 % for both Raw264.7 and HEK-293T cells at a concentration of 60 μg/mL. Significantly, DNA gel electrophoresis experiments, using ethidium bromide (EB) as a reference, confirmed the ability of the NCs to bind DNA. Furthermore, the as-prepared Ficin-Ni NCs could achieve precise imaging of cell nuclei consistent with 4',6-diamidino-2-phenylindole (DAPI) within 15 min in a variety of animal cells, including HEK-293T cells, Raw264.7, bullfrog erythrocytes, and human oral epithelial cells. Simultaneously, Ni NCs also demonstrated remarkable potential for visualizing the nuclear structures in plant cells, such as onion and cinnamon epidermal cells. Therefore, this innovative fluorescent probe, initially prepared via biomineralization, emerges as a promising alternative to traditional EB or DAPI dyes, paving the way for rapid response, effectiveness, and reusability in cellular imaging.

mailto:Soft rot caused by Dickeya zeae is an important bacterial disease affecting rice and other plants around the world. Several studies found that the specific virulence factor-modulating quorum sensing (vfm-QS) system is present in bacteria. vfmI is the key member encoding a two-component system sensor histidine kinase. Therefore, to determine the effects of vfm-QS on phenotypic features and virulence, the system was inactivated through the construction of a vfmI mutant in the D. zeae WH1 strain. The results of the phenotypic features and pathogenicity assays revealed that the deletion of vfmI abolished motility and reduced biofilm-forming capacity. Moreover, the mutation had a limited role in regulating the activity of plant cell wall-degrading enzymes (PCWDEs) and decreased the maceration of potato tubers in the tested dicotyledonous plants. Importantly, the vfmI mutant became avirulent to the rice plants, although the gene mutation slightly increased rice seed germination. These features are considerably different from those that have been shown for other Dickeya strains. Finally, our findings indicated that the vfm system controls the motility of WH1 by regulating flagellar biosynthesis and biofilm formation, which is achieved by regulating the intracellular c-di-GMP level. Taken together, these findings highlight the complexity and plasticity of QS regulatory circuits in the D. zeae strain.

To solve the problems of low utilization over the solar spectrum, elevating the photon absorption efficiency and exploiting long-wavelength photons are of great significance. Herein, a CdSe/polydopamine(PDA)@SiO₂ core-shell opal photonic crystal structure with excellent photothermal effect and photon absorption was fabricated for the first time. The photonic bandgap (PBG) effect and the slow photon effect of the photonic crystal structure helps the absorbing of photons and the photothermal effect of PDA coating shells provides higher reacting temperature for photocatalysis. Consequently, the S2P0 sample (without PDA coating) whose PBG is consistent with the absorption edge of CdSe photocatalyst exhibits a three times higher CO₂ reduction efficiency. Benefited from the photothermal effect of PDA, the S2P20 sample (20% PDA coating) shows a 4.77-fold efficiency than the blank sample, proving the reliability of the design. Moreover, the PDA shells enhance the adhesion for robust photonic crystal films and show other applications in fields like textiles. This work demonstrates a synergistic utilization of photothermal effect and photonic crystal structure for efficient photocatalytic CO₂ reduction and revealing more potential applications.

'Hot Jupiters' may not be orbiting alone

Astronomers challenge longstanding beliefs about the isolation of 'hot Jupiters' and proposes a new mechanism for understanding the exoplanets' evolution. Research led by an Indiana University astronomer challenges longstanding beliefs about the isolation of "hot Jupiters" and proposes a new mechanism for understanding the exoplanets' evolution. While our Jupiter is far away from the sun, hot Jupiters are gas giant planets that closely orbit stars outside our solar system for an orbital period of less than 10 days. Previous studies suggested they rarely have any nearby companion planets, leading scientists to believe that hot Jupiters formed and evolved through a violent process that expelled other planets from the area as they moved closer to their host stars. The research team's findings reveal that hot Jupiters do not always orbit alone. "Our research shows that at least a fraction of hot Jupiters cannot form through a violent process," said Songhu Wang, assistant professor of astronomy in the College of Arts and Sciences. "This is a significant contribution to advance our understanding of hot Jupiter formation, which can help us learn more about our own solar system." Wang presented the results of the research at the June 2023 meeting of the American Astronomical Society in Albuquerque, New Mexico. Researchers analyzed the full, four-year data set for hot and warm Jupiters from NASA's Kepler Mission. Warm Jupiters have a longer orbital period that ranges from 10 to 300 days. Researchers used transit timing variations to determine that at least 12% of hot Jupiters and 70% of warm Jupiters have a nearby planetary companion orbiting their host stars. Wang and his collaborators combined their results with existing observational constraints to propose a new framework for explaining the evolution of hot and warm Jupiters and why some have companion planets. They determined that the makeup of hot and warm Jupiter systems depends on the occurrence of gas giants in the system, which impacts how much the planets interact and migrate. The findings provide a launching point into future research about exoplanets and our solar system's planets. "The ultimate goal for astronomers is to set our solar system into the bigger picture -- 'Are we unique?'" Wang said. "This helps us to understand why we don't have a hot Jupiter in our solar system." Additional collaborators are Dong-Hong Wu, lecturer in the Department of Physics at Anhui Normal University, and Malena Rice, 51 Pegasi b Fellow at the Massachusetts Institute of Technology and incoming professor at Yale University. Wang has long been interested in the configurations and demographics of exoplanets. He uses observational research to try to understand their dynamics and origins, helping astronomers better understand how our solar system fits into a larger cosmic context.
