Summary: Mercury concentrations have significantly increased in oceans, with seafood consumption being a main pathway of toxicity in humans. Analysis of two squid species off Martinique showed a negative linear relationship in stable isotope ratios. Despite no significant trend between sulfate availability and mercury concentrations, all squid samples had levels below the safe consumption limit.

Summary: Researchers have found that electrons in moire flat band systems can break time-reversal symmetry, leading to a quantized anomalous Hall effect, with magnetism primarily orbital in nature. The study also reveals a significant change in magnetization as the chemical potential crosses the quantum anomalous Hall gap, consistent with the expected contribution of chiral edge states to the magnetization in an orbital Chern insulator. Additionally, mapping the spatial evolution of field-driven magnetic reversal shows reproducible micrometer-scale domains pinned to structural disorder.

Summary: Micro-X is an X-ray sounding rocket payload that had its first flight in July 2018. Despite facing a failure in the attitude control system, the first flight achieved partial success and a re-flight is scheduled. Additionally, modifications have been made to improve the detector systems and initial laboratory results have been obtained.

Summary: In this study, a superconducting quantum interference device (SQUID) has been constructed in magic-angle twisted bilayer graphene (MATBG) with control over the superconducting phase difference through a magnetic field. The observation of magneto-oscillations of the critical current demonstrates the long-range coherence of superconducting charge carriers in the material, with potential applications in various devices.

Summary: This study used Peruvian squid meat as the primary material to prepare thin slices of dried squid meat paper mixed with pork. The changes in physicochemical properties, microstructure, and sensory evaluation of the meat paper were analyzed. The results showed that the best quality meat paper was obtained with 20% squid surimi substitution, which had higher expansion rate, lower peroxide value, and moisture content. The food-borne microorganisms were within legal limits or negative.

Summary: The study found that the dietary composition of the Argentine shortfin squid shifts from crustaceans to fishes and cephalopods as they grow, with a significant increase in fish consumption in recent years. Artifacts, including plastic materials, were detected in 19.9% of the squid stomachs, highlighting the need for environmental monitoring to protect the squid and ensure aquatic food safety.

Summary: The biogeography of American loliginid squids has been significantly improved through the reanalysis of the genus Lolliguncula, resulting in the identification of five monophyletic lineages. The recent speciation between L. argus and L. diomedeae is attributed to oceanic environmental changes associated with glaciation, deep sea cooling, and tropical upwelling.

Summary: Most animals have long-term symbiotic associations with bacteria, which are crucial for their normal physiological functions. The symbiosis between the Hawaiian squid Euprymna scolopes and the bioluminescent bacterium Vibrio fischeri is a significant model for studying the molecular mechanisms that promote animal-bacterial symbioses. A simplified and reproducible protocol has been developed to determine appropriate inoculum levels and standardize the assay, requiring fewer animals and capable of detecting changes in the symbiotic capacity between different strains.

Summary: The study investigated distribution patterns of light fisheries in the South China Sea using nighttime light remote sensing data from 2016. Seasonal and spatial patterns of light-fishing activities were identified, with a new hotspot observed in the open ocean during spring. Comparisons were made between VMS and DNB data to study fishing behaviors of Chinese large-sized, falling-net fishing fleet.

Summary: In this research, we developed a miniature swarm platform with autonomous planner and onboard perception, localization, and control functions, enabling swarm navigation and coordination in dense forests and other complex environments. The planner meets various task requirements, can work in a timely and accurate manner based on limited information, and obtains high-quality trajectories through spatial-temporal joint optimization.

Summary: The study revealed differences in microstructural and chemical properties between neon flying squid (OB) and jumbo squid (DG) mantles after frozen storage. Jumbo squid showed better stability in myofibrillar protein (MP) content compared to neon flying squid. Label-free proteomic analysis identified various differentially abundant proteins (DAPs) in the mantles of both species, with some proteins improving the stability of jumbo squid in response to freezing-induced changes.

Summary: Seabirds have evolved various adaptations to thrive in hostile conditions, including specific coloration and wing pigmentation. Studies show that the darker wings of seabirds heat up under high solar irradiance, improving flight efficiency. These findings suggest that seabirds have evolved wing pigmentation to enhance flight performance in extreme ocean conditions, with potential implications for bioinspired innovations in aerospace and aviation.
