Summary: The Guanshan Biota in the Cambrian Stage 4 reveals an ecological transition from trilobite-dominated to brachiopod-dominated communities. The presence of parasitic tube worms associated with palaeoscolecidomorphs and brachiopods provides evidence of biological interactions in the ecosystem. This study highlights the complexity of early Cambrian ecosystems and the role of brachiopods as ecosystem engineers.

Summary: Bryozoans, also known as ectoprocts or moss animals, are aquatic, primarily sessile, filter-feeding lophophorates that construct an organic or calcareous colonial exoskeleton. Fossils of Protomelission gatehousei from the early Cambrian of Australia and South China have been identified as potential stem-group bryozoans, pushing back the origin of the phylum Bryozoa by approximately 35 million years and aligning it with other skeletonized phyla in the Cambrian Age 3. This discovery reconciles the fossil record with molecular clock estimations of an early Cambrian origin and subsequent Ordovician radiation of Bryozoa following the acquisition of a carbonate skeleton.

Summary: The main animal lineages diversified in the Cambrian period, while the diversity at lower taxonomic ranks emerged gradually over the next 500 million years. Annelid worms appear to follow this pattern, with early-diverging crown-group annelids found in Cambrian Burgess Shale deposits and more derived polychaete families appearing in later periods. However, the discovery of 15 new fossils of the 'phoronid' Iotuba chengjiangensis challenges this view, as they exhibit similarities to derived polychaete families, indicating an earlier origin of modern annelid diversity.

Summary: Analyzing the growth dynamics of trilobites revealed significant changes in post-embryonic axial growth at different developmental stages, which are closely related to sexual maturity in extant euarthropods. The observed body segmentation patterns in trilobites suggest a complex series of changing growth controls, indicating a more complex development than previously thought.

Summary: The origins of animal phyla and their body plans can be traced back to a burst of evolution during the Cambrian period. However, the fossil remains of the phylum Bryozoa, known as colonial 'moss animals', have been difficult to identify due to their similarities with other animal and algal groups. The phosphatic microfossil Protomelission is currently the strongest candidate for Bryozoa fossils, but new findings suggest that it may actually be the earliest dasycladalean green alga and not a bryozoan.

Summary: Genic and genomic data have reshaped our understanding of the Cambrian Evolutionary Radiation, not only by rearranging phylogenetic topologies but also by deciphering deep homologies. The study of problematic fossils from early Cambrian Lagerstatten, like the Chengjiang biota, reveals controversies in their interpretation and impacts on understanding early animal evolution. Despite difficulties, a testable method for interpreting fossils has emerged, making Cambrian problematic fossils valuable in the parsing tree of animal evolution.

Summary: The research found that REY in the Zhijin phosphorite mainly exists in apatites by isomorphous substitution, adsorbed by Fe-/Mn oxides/hydroxides or organic matters. Nd and Ce-anom plots indicate lower sedimentation rates of REY, allowing sufficient time for REY absorption in seawater. Apart from variations in ocean chemistry, constrained paleogeography provided a suitable space for REY entering apatite crystals.

Summary: Although there is little direct information available on the muscle systems of early animals, this study describes exceptionally preserved muscles in benthic olivooid medusozoans from the basal Cambrian, providing the oldest record of a muscle system in cnidarians. These muscles likely helped early Cambrian jellyfish to develop jet-propelled swimming within the water column.

Summary: New well-preserved specimens of Anabarella were found in the Yanjiahe Formation in the Three Gorges area, confirming the presence of A. plana and revising the taxonomy of the genus in South China. The microstructures of A. plana suggest that it may have had a semi-infaunal mode of life and indicate its potential ancestral relationship with Watsonella.

Summary: Pesticide residues in fruit and vegetable pose a significant threat to human health. A new method utilizing WPU@AgNPs sticky tapes was developed for rapid extraction and surface-enhanced Raman scattering (SERS) assay of thiabendazole residues on fruit surfaces. The WPU@AgNPs tapes, constructed by coating silver nanoparticles (AgNPs) on waterborne polyurethane (WPU) films, demonstrated excellent sensitivity using 4-Mercaptopyridine (4-Mpy) as the probe molecule. The tapes allowed for easy detection of thiabendazole residues on pear, apple, and banana surfaces, with a detection limit of 1.44, 1.12, and 1.63 ng/cm2, respectively. This strategy could be a common method for rapid, on-site, and ultra-sensitive assay of thiabendazole residues in both chemical and biological fields.

Summary: Through the chronology study of lacustrine deposits of the Upper Dingqing Formation in the Lunpola Basin, Central Tibet, it has been determined that the geological period is middle Miocene (15-12 Ma). Stable isotope and palynological records indicate a climatic transition around 13.8 Ma, characterized by cooler and drier climate. New palynological elevation reconstructions suggest a maximum paleo-elevation of 3100-3600 m (average 3350 m) for the Lunpola Basin, consistent with floating-leaf plants data. This study provides new insights into paleoenvironmental reconstructions and paleo-elevation estimates of the Lunpola Basin, Central Tibet.

Summary: The effect of solute hydrogen on shear-coupled grain boundary migration was studied and the dual role of hydrogen on grain boundary mobility was revealed. At low temperature and high loading rate, where hydrogen diffusion is slower than grain boundary motion, the grain boundary breaks away from the hydrogen atmosphere and transforms into a new stable phase with enhanced mobility. In the reverse regime, hydrogen atoms move along with the grain boundary, exerting a drag force and decreasing its mobility. These findings provide a rationale for the coexistence of hydrogen hardening and softening observed experimentally in polycrystalline materials.

Summary: This study reveals that the skeletons of early Cambrian mollusks and hyoliths are composed of fibrous microstructures made of calcite, which had not been discovered before. Additionally, it shows that the shells of these early animals were mainly composed of aragonite. This has important implications for understanding the significance of early biomineralization and its relationship with seawater chemistry.

Summary: Glauconite, a prevalent authigenic clay mineral found in marine sedimentary successions, has a long history of dating but fell into disfavor due to difficulties in obtaining pure glauconite separates. Recent advancements in sedimentary petrography and reaction cell mass spectrometry offer the potential for rapid in situ Rb-Sr dating of glauconite, but caution is needed due to burial alteration. This study combines mineral mapping, geochemical characterization, and in situ Rb-Sr dating to address the impact of postdepositional alteration on glauconite and proposes a screening approach for identifying well-preserved glauconite grains.

Summary: Recently, hydrogen-assisted failures have been observed on nickel alloys used in the subsea oil and gas industries. This study investigates the hydrogen diffusion behavior in a nickel Alloy 625 under various pre-strain levels. The results show that while an increase in strain levels reduces hydrogen diffusivity, there is an acceleration in hydrogen diffusion when the strain exceeds a certain level, likely due to hydrogen-enhanced strain-induced vacancy formation at grain boundaries and reduced hydrogen trapping by fractured carbides.

Summary: In this article, high spatiotemporal resolution data obtained by China's APOD satellite are used to study the hemispheric asymmetry of thermospheric density. The results show a strong hemispheric asymmetry of thermospheric atmospheric density response during the magnetic storm, with the atmospheric density in the southern polar region (SPR) on the duskside being higher than that in the northern polar region (NPR). The hemispheric density response asymmetry is related to local time (LT).

Summary: Small skeletal fossils from the early Cambrian Guojiaba Formation in southern Shaanxi, China were reported for the first time. The fossils include a wide variety of skeletal clades, such as brachiopods, sphenothallids, archaeocyaths, bradoriids, sponge spicules, echinoderm plates, and trilobite spines. The archaeocyaths found in the Guojiaba Formation are older than those previously described from the Xiannvdong Formation. The fossil assemblages from the Guojiaba Formation resemble those from the upper Yu'anshan Formation (Chengjiang Fauna) in eastern Yunnan Province, supporting the correlation of the Guojiaba Formation with the Chiungchussuan Stage (Stage 3 of Cambrian Series 2).

Summary: In this paper, a novel dual-stream Transformer (DSTrans) is proposed for hyperspectral image (HSI) restoration, addressing the challenges of limited training samples and the difficulty in capturing long-range dependencies. The DSTrans consists of dual-stream attention and dual-stream feed-forward network, effectively capturing spectral dependencies and global spatial interactions. Additionally, a multi-tasking network is utilized to jointly train the RGB image task and HSI task. Experimental results demonstrate that the proposed method achieves state-of-the-art performance in HSI restoration tasks.

Summary: In recent years, the ternary strategy has been proven effective in improving the performance of organic solar cells (OSCs). By adding an asymmetric medium-band gap non-fullerene acceptor (AFIC) as a third component into the PM6:BTP-eC9 binary blend, a highly efficient ternary OSC is achieved. The AFIC exhibits well-complementary absorption spectrum with the host blend, enhancing light harvesting and improving charge transport in the ternary devices. As a result, the ternary OSC demonstrates a significantly improved power conversion efficiency (PCE) of 18.7% compared to the binary OSC's PCE of 17.5%, attributed to the synergistic enhancement of Voc, Jsc, and FF.

Summary: Through analyzing the whole-genome sequences of 795 wheat accessions, it was found that bread wheat originated from the southwest coast of the Caspian Sea and underwent a slow speciation process. It gradually spread across Eurasia in the past few thousand years and formed diversified adaptive landscapes in novel environments. In contrast, the cultivated relatives of bread wheat experienced a population decline due to human food choice shift, and many wheat relatives are predicted to continue shrinking in the future due to climate change. These findings will guide future efforts in protecting and utilizing wheat biodiversity to enhance global wheat production.
