Summary: This study discovered a new symbiotic mechanism, the ayRhp1-mediated symbiosomal NH4+-trapping mechanism, which promotes nitrogen delivery to algae during the day for sustaining photosynthesis and restricts nitrogen delivery at night to keep algae under nitrogen limitation. Additionally, ayRhp1 facilitates CO2 diffusion, which may have implications for metabolic dysregulation and bleaching.

Summary: Emersion affects water-breathing animals’ ability to regulate respiratory gas exchange, acid-base balance, and nitrogenous waste excretion. Helice formosensis mitigates these effects by altering urine and branchial water, but prolonged emersion may result in overcompensatory metabolic alkalosis. During emersion, ammonia can be temporarily converted to alanine, indicating a unique adaptation mechanism in these crustaceans. Additionally, Helice formosensis can actively suppress desiccation by producing hyperosmotic urine.

Summary: Cement production can be decarbonized by using electrochemical reactors to convert limestone into cement clinker precusor and release CO2 as a pure stream. A cement electrolyzer with a cell voltage of 1.8 V and 100 mA cm(-2) current density is reported, improving upon the previous record. Use of H-2 in the electrolyzer decreases the cost of cement production compared to using H-2 as a kiln fuel, as shown by a techno-economic model. This work advances the feasibility of electrochemical cement production.

Summary: Despite its versatility, the involvement of RNA m6A methylation in shrimp's response to ammonia nitrogen toxicity is not well understood. This study characterized the dynamic RNA m6A methylation landscapes induced by toxic ammonia exposure in the Pacific whiteleg shrimp. The global m6A methylation level decreased significantly after ammonia exposure, and many m6A methyltransferases and binding proteins were repressed. The differentially methylated genes were enriched in pathways related to metabolism, immune defense, and apoptotic signaling.

Summary: This study assesses the variation in hypoxia tolerance observed in fishes within a phylogenetic context. It found that hypoxia tolerance has a clear phylogenetic signal and is affected by factors such as temperature, body mass, cell size, salinity, and metabolic rate. Marine fishes are more susceptible to hypoxia than freshwater fishes, and fishes with higher oxygen requirements are also more susceptible to hypoxia. Additionally, hypoxia and warming may act synergistically, leading to lower hypoxia tolerance in warmer waters.

Summary: The acclimatization of certain ectothermic vertebrates to winter conditions involves reduced energy consumption, achieved through decreased movement activity, depression of cellular functions, or switching to anaerobic energy production. This study on crucian carp showed that winter-acclimatized fish exhibited lower metabolic rates and a shift to anaerobic energy production during anoxia. Winter dormancy in crucian carp is achieved through active reduction of energy consumption, a slowed metabolic rate, and a direct response to oxygen absence.

Summary: According to life-history theory, there might be different immunological strategies between reproductive and non-reproductive periods due to limited resources. Our study on two sympatric marine fish species, rockfish and sandperch, found that reproductive individuals showed lower immune function, but higher levels of natural antibodies in rockfish females, compared to their non-reproductive counterparts. On the other hand, reproductively active sandperch males showed lower levels of natural antibodies and higher neutrophil to lymphocyte ratio and spleen index compared to non-reproductive males. The study highlights the species-specific patterns of immunity and the potential influence of resource limitation and abiotic factors on immune trade-offs in fish.
