Summary: In this study, we demonstrate an electron beam direct-write process in an aberration-corrected scanning transmission electron microscope. This process differs from conventional electron-beam-induced deposition techniques as it uses a different mechanism and elemental tin (Sn) as a precursor to enable atom-by-atom direct writing. The atomic-sized electron beam is used to generate chemically reactive point defects in a graphene substrate, allowing the precursor atoms to migrate and bond to the defect sites for deposition.

Summary: This paper investigates the damage and failure behaviors of thin-walled coilable composite shells during snap-through and coiling up. Multiscale models are established to compute the mechanical properties and the results are verified through experiments. The dominant damage is found to be the failure of the matrix, and it can be relieved by increasing the hub diameter.

Summary: The engineering of quantum materials involves the development of tools for synthesis and characterization challenges. One key factor is atomic-scale modification for desired atomic structures. The use of scanning transmission electron microscopes (STEMs) allows for atomic-scale material manipulation but obstacles like in situ material delivery exist. This article presents progress on in situ thermal deposition platform for synthesis processes in a scanning transmission electron microscope.

Summary: Spin chains proximitized by s-wave superconductors are predicted to enter a mini-gapped phase with topologically protected Majorana modes (MMs) localized at their ends. However, the presence of non-topological end states mimicking MM properties can hinder their unambiguous observation. Here, we report on a direct method to exclude the non-local nature of end states via scanning tunneling spectroscopy by introducing a locally perturbing defect on one of the chain's ends. We apply this method to particular end states observed in antiferromagnetic spin chains within a large minigap, thereby proving their topologically trivial character. A minimal model shows that, while wide trivial minigaps hosting end states are easily achieved in antiferromagnetic spin chains, unrealistically large spin-orbit coupling is required to drive the system into a topologically gapped phase with MMs. The methodology of perturbing candidate topological edge modes in future experiments is a powerful tool to probe their stability against local disorder. Spin chains on superconductors have been studied as a possible venue for zero-energy Majorana bound states at the ends of the chain. Here, the authors observe localized end states in antiferromagnetic chains, but rule out a Majorana origin of these states by perturbing them with local defects.

Summary: The mortality of Crassostrea gigas juveniles is systematically observed every year worldwide, primarily due to Pacific Oyster Mortality Syndrome (POMS) caused by OsHV-1 infection. During the oyster mortality episode, releases of OsHV-1 and opportunistic bacteria were observed in the water, potentially impacting disease spread within oyster farms and marine biodiversity in shellfish farming areas.

Summary: Biomineralization is a complex process bio-controlled by living organisms, involving physical and chemical processes such as ionic concentration regulation and organic molecules production. This study investigates the early-mineralized calcareous units from two bivalve species using advanced optical and X-ray microscopy methods, revealing chemical and crystallographic insights. The observed ring-like structural features in calcite units are correlated with the absence of calcite and an increase in amorphous calcium carbonate and proteins content. Based on these findings, a temporal biomineralization cycle is proposed, providing biomimetic perspectives for designing crystalline materials.

Summary: Pearl-farming in French Polynesia is a significant source of income, but plastic pollution poses a threat to marine life and the economy. Research shows widespread contamination of microplastics in surface water, water column, and cultivated pearl oysters, with high levels in the water column. Small, fragment-shaped microplastics are prevalent, likely resulting from the breakdown of larger plastic debris.

Summary: This study found that early microbial exposure in Pacific oysters can significantly improve their survival rate against a pathogen causing mortality syndrome. The protection provided by microbial exposure is inheritable across generations and is associated with changes in epigenetic marks and immune gene expression. This discovery suggests that microbial exposure may be an important strategy for protecting oyster aquaculture from infectious diseases.

Summary: In Pacific Oyster Mortality Syndrome (POMS), Vibrio harveyi and ostreid herpesvirus 1 (OsHV-1) are the predominant bacteria causing the disease. V. harveyi synergizes with OsHV-1 by promoting mutual growth and inhibiting oyster's cellular defenses. Furthermore, V. harveyi produces metabolites that benefit the growth of coexisting V. rotiferianus.

Summary: The study used metabarcoding and metatranscriptomic approaches to show that the pathogenesis of POMS is conserved across different infectious environments, and identified a core bacterial consortium that plays a role in POMS pathobiota. The core bacteria have complementary metabolic functions and a low competition for nutrients, which allows them to colonize host tissues and contribute to the conservation of POMS pathobiota.

Summary: The study investigated the physiological responses of Tridacna maxima to temperature and pCO(2) conditions predicted for French Polynesian lagoons in 2100. Results showed that both temperature and pCO(2) had negative impacts on the physiology of the giant clams, affecting oxygen production, symbiont photosynthetic yield, and shell growth rate. The findings suggest that the current environmental conditions may pose a threat to the survival of T. maxima in the future.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
