Summary: This study conducted a survey on the distribution of horseshoe crabs along the northcentral Gulf of Mexico coast and found that their presence was mainly concentrated in western sites, influenced by the distance from areas of high freshwater discharge and interannual weather variation. Land cover, especially Bare Land and Estuarine Emergent Wetland classes in western sites, was identified as an important factor affecting the occurrence of horseshoe crabs.

Summary: The study found that circulating bile acids capable of inducing immunosuppression are present in septic shock patients, particularly in those with severe liver failure. Future research may need to explore whether modulating bile acid metabolism can improve the clinical course and outcome of sepsis in these patients.

Summary: Horseshoe crabs are marine creatures with a fossil record dating back to the Paleozoic era, displaying extreme xiphosurid morphologies that reflect adaptations to various environments. Recent taxonomic examination has led to the identification of the Austrolimulidae family, with new material supporting the diverse evolution within this group during the Triassic period.

Summary: The study found that exposure to nanoplastics and heavy metals had complex effects on the antioxidant enzyme parameters of juvenile tri-spine horseshoe crabs, leading to both increased and decreased levels of certain parameters. The results during the recovery period showed changes in antioxidant enzyme parameters in each experimental group, demonstrating adverse effects of nanoplastics and heavy metals on juvenile horseshoe crabs.

Summary: This study assessed the impact of artificial sound on the red hermit crab and its symbiotic sea anemone. The results showed that both the crab's statocyst and the anemone's tentacle sensory epithelia were damaged when exposed to low-intensity, low-frequency sounds. Although the righting reflex time of the crab was not strongly affected, with only an increase in the range of righting times, the findings suggest that anthropogenic sound effects on invertebrate species may have direct consequences in the entire ecosystem, considering the increasing levels of low-frequency sound in the ocean and the limited data on invertebrate bioacoustics.

Summary: Constraining the timing of morphological innovations within xiphosurid evolution is important for understanding how this long-lived group exploited ecological niches. By revisiting four Australian taxa, the study determines that Paterson Limulus originated after the Permian and over-developed genal spine structures are exclusive to the Triassic in Austrolimulidae. The study also used synchrotron radiation X-ray tomography to examine the holotypes of the four xiphosurids.

Summary: This study used individually randomized trials labeled as pragmatic in the years 2014-2019 to describe the prevalence of multiple primary outcomes, changes in primary outcomes and target sample sizes between protocols and final reports, and how issues of multiplicity are addressed in pragmatic trials.

Summary: This study compares the decision thresholds of fingerprint examiners and the general public. The results demonstrate that fingerprint examiners are more risk averse and their decision criteria align with error rate studies.

Summary: The study focused on the physico-chemical characteristics of mangrove horseshoe crab shells and identified their potential for developing bio-foam insulator material. The unique foam structure of the shells can be utilized for new marine biomaterials, and the formation and composition of the foam are believed to serve multiple functions.

Summary: Horseshoe crabs are ancient creatures with ecological and biomedical importance. This study investigated the tetrodotoxin (TTX) concentrations in two HSC species at different life stages in their spawning and nursery grounds in the northern Beibu Gulf, China. The results showed that TTX levels were higher in the hemolymph of early-instar juvenile T. tridentatus, but had little association with sampling location and growth stages. These findings provide valuable insights into the occurrence and distribution of TTX in HSCs during their spawning season.

Summary: Several studies have shown that most climate models underestimate cloud cover and overestimate cloud reflectivity, particularly for the tropical low-level clouds. Through analyzing the characteristics of low-level tropical marine clouds simulated by six climate models, it is found that these models still exhibit a bias of too few and too bright clouds, and the reflectivity is particularly overestimated when cloud cover is low.

Summary: Despite diverse non-human hosts and recent spillover events, only a small number of coronaviruses persist in human populations, indicating significant barriers to establishment. Possible explanations include issues of ascertainment, historically lower opportunities for spillover, human demographic changes, pathogen biology, and pre-existing adaptive immunity. Successful emergent viral species must balance transmission, virulence, and host immunity to maintain circulation, outlining promising research directions to understand the combinations of pathogens and contexts leading to spillover.
