Article Abstract
We report precise manipulation of the potential-energy surfaces (PESs) of a series of butterfly-like pyrazolate-bridged platinum binuclear complexes, by synthetic control of the electronic structure of the cyclometallating ligand and the steric bulkiness of the pyrazolate bridging ligand. Color tuning of dual emission from blue/red, to green/red and red/deep red were achieved for these phosphorescent molecular butterflies, which have two well-controlled energy minima on the PESs. The environmentally dependent photoluminescence of these molecular butterflies enabled their application as self-referenced luminescent viscosity sensor.

Introduction: Maize is one of the first crops to benefit from heterosis, significantly enhancing commercial breeding. Despite extensive research, the molecular mechanisms of heterosis remain elusive.
Objectives: This study integrates a novel genetic framework with transcriptomic and phenotypic analyses to identify heterosis-related genes and uncover their regulatory mechanisms.

Generative models cover various application areas, including image and video synthesis, natural language processing and molecular design, among many others. As digital generative models become larger, scalable inference in a fast and energy-efficient manner becomes a challenge. Here we present optical generative models inspired by diffusion models, where a shallow and fast digital encoder first maps random noise into phase patterns that serve as optical generative seeds for a desired data distribution; a jointly trained free-space-based reconfigurable decoder all-optically processes these generative seeds to create images never seen before following the target data distribution.

Unlabelled: Anthropogenic activities induce drastic changes in land use that are at least partly responsible for the ongoing global patterns of macro-biodiversity erosion. These habitat changes also impact the fitness of the resilient species, through direct effects on diet and/or indirect environmental effects. Although microbial communities associated with species can crucially influence a diverse set of their host's biological functions, studies on how microbial communities associated with wild species respond to habitat degradation remain scarce.

Wings are key organs for insect diversity and adaptation. Wing discs are the starting point for wing development in insects, and their developmental mechanisms are central to wing formation. In silkworms, which serve as a general model for studying insect wing development, wing disc development is influenced by many factors.

The goal of meiosis is typically to produce haploid gametes (eggs or sperm). Failure to do so is catastrophic for fertility and offspring health. However, Lepidopteran (moths and butterflies) males produce two morphs of sperm: nucleated (eupyrene) sperm which fertilize the egg, and anucleated (apyrene) sperm, both of which are essential for fertilization.
