Summary: Optical holography plays significant roles in various applications. Conventional holography only considers the phase and intensity of light, neglecting polarization information. Vectorial holography, empowered by metasurfaces with multiple degrees of freedom, provides more versatile control over polarization states and spatial distributions of light, extending the scope of holography. Considering the full vectorial nature of light field dramatically increases the information carried by light, promising high performance and multifarious functionalities.

Summary: Cadmium (Cd) is a harmful heavy metal contaminant, and long non-coding RNAs (lncRNAs) play significant roles in plant response to Cd stress. Transcriptome analysis of Cd-tolerant and Cd-sensitive barley genotypes revealed novel lncRNAs and differentially expressed lncRNAs between the two genotypes. Prediction and experimental analysis showed that some lncRNAs may act as target mimics of miRNAs in barley. Functional analysis of a key lncRNA demonstrated its important role in plant Cd tolerance.

Summary: A van der Waals crystal, niobium oxide dichloride (NbOCl2), has been found to exhibit weakened interlayer electronic coupling and monolayer-like excitonic behavior in the bulk form. It also has a scalable second-harmonic generation intensity that is three orders higher than that in monolayer WS2. Additionally, the strong second-order nonlinearity in thin flakes as thin as 46 nm enables correlated parametric photon pair generation through a spontaneous parametric down-conversion (SPDC) process. This is the first SPDC source demonstrated in two-dimensional layered materials and the thinnest SPDC source ever reported. This research opens avenues for developing van der Waals material-based ultracompact on-chip SPDC sources and high-performance photon modulators in both classical and quantum optical technologies.

Summary: Spin-orbit interactions in evanescent fields have attracted significant interest, particularly in relation to the generation of polarization-dependent lateral forces on particles. However, the relationship between polarization-dependent resonances of large particles and incident light's helicity and resultant lateral forces remains unclear. In this study, a microfiber-microcavity system was used to investigate these phenomena. Contrary to previous studies, it was found that induced lateral forces at resonance are not proportional to the helicity of incident light due to polarization-dependent coupling phases and resonance phases. A generalized law for optical lateral forces was proposed, revealing the existence of optical lateral forces even when the helicity of incident light is zero.

Summary: Comparing the leaf metabolome and transcriptome of tomato plants grown under SCP, chemical fertilizer, and organic fertilizer, it was found that SCP treatment improved primary and secondary metabolism in tomato leaves, promoted growth, and reduced environmental emissions. SCP also down-regulated ethylene-related genes, while up-regulating jasmonic acid and gibberellin related genes, leading to a balanced growth and environment adaptation ability in plants. This study provides insight into the molecular and metabolomic responses of tomato plants to SCP treatment, contributing to the development of climate-smart agriculture.
