Summary: This study provides the first comprehensive data on the characteristics, biology, and genetics of the shamefaced crab Calappa granulata from the central eastern Adriatic Sea. The study reveals the crab's dietary preferences, size at first sexual maturity, and presence of epibiotic polychaetes. The analysis of genetic sequences also suggests a homogenous population in the Adriatic Sea.

Summary: This study investigated the embryonic development of the mud crab Scylla paramamosain by analyzing three critical parameters: egg color, embryo morphology, and cell division distribution. The findings provide important insights into the embryonic development of the crab and have potential applications in S. paramamosain culture for determining the developmental status and obtaining high-quality seeds.

Summary: This study analyzed European VLBI Network data of the Crab Pulsar at 1658.49 MHz and investigated the rates, fluence, phase, and arrival time distributions. The analysis revealed that giant pulses represent about 80% of the total flux and the likelihood of finding another giant pulse is influenced by the time interval between bursts.

Summary: Metopaulias depressus is a non-marine crab endemic to Jamaica with limited genomic resources. The complete mitochondrial genome of M. depressus was reported, showing adaptability to terrestrial life and purifying selection in protein-coding genes. Differences in tRNA secondary structures were observed, contributing to a new genomic resource for this species.

Summary: In this paper, the authors present the detection of polarized dust emission in the Crab pulsar wind nebula and constrain the composition and properties of the dust. They find the presence of large grains and the coexistence of carbonaceous and silicate grains in the Crab Nebula. The study also provides the temperature and mass ranges of the dust.

Summary: Retrograde perfusion may lead to vasomotor responses, edema formation, or inflammation around vessels. The study showed immediate effects of flow reversal with increased perfusion pressure and cytokine levels. In the lungs, retrograde perfusion resulted in edema formation.

Summary: This review discusses the role of aerosols in the transmission of COVID-19, including virus transport, deposition in the respiratory system, and the importance of masks in reducing spreading. It also focuses on the physicochemical phenomena of the virus entering the surface of lung liquids.

Summary: This study investigates the consumption rates of fresh and senescent leaves by the mangrove tree-climbing crab and estimates its digestive ability. The results show that the crab consumes more fresh leaves than the senescent ones. Additionally, the study confirms the digestive ability of the crab on the nutrient-poor mangrove leaf litter.

Summary: The study revealed significant seasonal variations in the diet of the sally lightfoot crab, improving understanding of its trophic plasticity and potential dietary overlaps with other herbivore species. This feeding plasticity is advantageous for the successful spread of the species in the Mediterranean Sea.

Summary: Swimming crabs of the genus Portunus were revised based on genetic markers and morphological comparison, leading to the discovery of polyphyletic and paraphyletic composition of several genera. The revised composition divided Monomia, Portunus, and Xiphonectes into new genera, and the subfamily Portuninae now consists of 11 genera.

Summary: We described and illustrated a new species of Chaceus from the Regional Natural Park of the Serrania de Perija, Colombia. This discovery increases the number of Chaceus species, with three of them only found in Venezuela. We differentiated the new species based on the characteristics of its third maxilliped and first male gonopod, and also provided a distribution and identification key for the Chaceus species.

Summary: This study used the gill (Na+, K+)-ATPase as a molecular marker to analyze the effects of Co2+ on K+-phosphatase activity in the Blue crab Callinectes danae. The results showed that Co2+ can either stimulate or inhibit K+-phosphatase activity, and it has a higher affinity for the enzyme compared to Mg2+. The findings contribute to our understanding of the mechanism of action of Co2+ on crustacean gill (Na+, K+)-ATPase.
