A new study published in Big Earth Data applies the INFORM Climate Change model to project future risks of humanitarian crises and disasters by integrating climate hazards, population dynamics, conflict, and socioeconomic development pathways. Incorporating forward-looking projections of vulnerability and coping capacity under different Shared Socioeconomic Pathways, the analysis shows that global risk may decline under moderate and rapid development scenarios but could rise sharply in the high-emission, fragmented SSP3 pathway. The findings provide evidence for prioritizing vulnerable regions and guiding targeted risk reduction and climate adaptation strategies.

Fruit color is a key trait influencing consumer preference, nutritional value, and market competitiveness, yet the molecular coordination behind pigment formation remains incompletely understood.

Quantum dot light-emitting diodes (QLEDs) have emerged as a leading platform for next-generation display technologies, gaining substantial research attention in recent years. Among various patterning strategies, direct photolithography offers distinct advantages through its high resolution, throughput, and process simplicity. However, current direct photolithography approaches face critical limitations in resolution and device performance, primarily arising from surface defect generation and photodamage of quantum dots (QDs) caused by deep-ultraviolet exposure and photochemical byproducts. To overcome these challenges, Xiang, Zhang, and Gu et al.  present a novel benzophenone-derived photosensitive crosslinker featuring a byproduct-free C–H insertion mechanism with native ligands of QDs. Through precise structure design, the photo-absorption of the crosslinker extends to 365 nm, allowing the long-awaited QD patterning under standard i-line photolithography conditions. The developed crosslinker achieves unprecedented patterning resolution (pixel size ≈500 nm) with preserved photoluminescent characteristics. Corresponding QLED devices demonstrate remarkable performance enhancements, including a maximum external quantum efficiency (EQE) of 16.48% and a T₉₅ operational lifetime of 2258.3 hours (approximately 2.1 times longer than pristine devices). These advancements establish a promising pathway toward high-resolution and high-performance QLEDs, thereby accelerating the commercialization of high-end optoelectronic devices.

A multidisciplinary research team has developed a solar-powered photothermal-photocatalytic synergistic platform (SPSP) capable of simultaneously producing fresh water from seawater and degrading antibiotic pollutants. Published in Nano Research on August 21, 2025, the designed SPSP system demonstrates high efficiency in both water evaporation and contaminant removal, thus providing a sustainable, low-carbon solution for integrated water purification and agricultural irrigation.

Researchers from the School of Materials Science and Engineering at Harbin Institute of Technology, led by Professor Jiao's team, report a photoelectrochemical photodetector that integrates α-Ga₂O₃ nanorod arrays with CdS quantum dots. By exploiting the pyro-phototronic effect, the device operates at zero-bias, and exhibits a broadband spectral response from 220 to 700 nm with responsivities of 0.99 mA W⁻¹ at 254 nm and 1.48 mA W⁻¹ at 450 nm. The rise and fall times are 30 ms and 24 ms, respectively. Furthermore, the detector executes “AND”, “OR”, and “NOT” logic functions and successfully transmits the optical message “HIT”. These results provide a route toward broadband, fast-response, and low-power optoelectronic modules for optical communication and sensing.

A team of researchers has developed chiral plasmonic nanocatalysts that significantly enhance the efficiency and selectivity of converting CO₂ into methane using circularly polarized light. The catalysts, featuring helical gold-silver nanorods coated with mesoporous silica, achieve 95.8% electron selectivity for methane production—a 3.1-fold improvement over conventional catalysts—while suppressing competing hydrogen evolution. This breakthrough demonstrates the potential of polarization-controlled photocatalysis for sustainable fuel synthesis and CO₂ valorization.

A new study reveals a GaTe/PdSe₂ van der Waals heterostructure with unique type-II band alignment and reverse rectification. This device achieves remarkably low dark current, high reverse rectification ratio, and exceptional responsivity across an ultra-broad spectrum from ultraviolet to near-infrared (365–940 nm). It also demonstrates high polarization sensitivity, making it a versatile platform for next-generation advanced photodetection and optical communication applications.

A first-in-human trial from Institute of Science Tokyo and EVA Therapeutics, Inc., demonstrates that enteral ventilation, a technique that could deliver oxygen through the intestine, is safe and feasible in healthy subjects. The method involves intrarectal administration of an oxygen-carrying fluid into the gut, where oxygen may diffuse into the bloodstream. These findings provide important evidence for further testing of enteral ventilation as a potential alternative oxygenation method for patients with respiratory failure.
