Summary: Phase change materials store thermal energy as latent heat and can be combined with high thermal conductivity metals to create composites with high power density and large energy storage capacity. This study provides a theoretical framework to design and optimize cylindrical composites with three figures of merit - minimization of temperature rise, maximization of effective volumetric heat capacity, and maximization of effective heat capacity based on mass.

Summary: Liquid air energy storage (LAES) system utilizes packed bed thermal energy storage (PBTES) to improve system performance. Under ideal conditions, the system can generate 1.8 MWh of electricity during peak periods and achieve a payback period of 6.7 years with a total profit of 0.66 million dollars. However, the transient behavior of the system leads to a decrease in performance over different cycles.

Summary: Phase change energy storage technology (PCEST) can enhance energy utilization efficiency and address the issue of fossil energy depletion. Phase change materials (PCMs) play a crucial role in the development of PCEST. Solid waste is considered a valuable resource and has garnered significant attention for its comprehensive utilization. By encapsulating PCMs, solid wastes and their products can form stable PCMs (FS-PCMs) to overcome the problem of PCM leakage during usage. This review article examines the research on solid waste-based FS-PCMs, encompassing preparation strategies, application solutions, and future research recommendations, which can serve as references for related research and applications, and promote the advancement of solid waste-based FS-PCMs.

Summary: Previous studies found that the power output of jumping in frogs exceeds what is possible from muscle power alone, suggesting that jumping requires the storage and release of elastic strain energy. This study on Cuban tree frogs observed that muscle mass-specific work output and power output during jumping increased linearly with the work done, but the muscles were activated before the jump started. The preactivation duration and EMG amplitude also increased with increasing amounts of work performed.

Summary: This article examines the rate at which reversible phenotypic plasticity (RPP) occurs and its potential impact on how organisms overcome environmental challenges. The study suggests that current theoretical models do not consider the evolutionary potential of RPP rates. If the rate of plasticity itself can evolve, it may alter the organism's perception of environmental predictability and influence the slope of the evolved reaction norm. The optimization of phenotypic plasticity rates, their evolutionary dynamics in different environments, and the costs associated with them warrant further exploration in future research.

Summary: Phenotypic plasticity allows organisms to optimize traits for their environment. The transition from juvenile-to adult-vegetative development, known as vegetative phase change (VPC), contributes to age-dependent changes in phenotypic plasticity. The timing of VPC and the acquisition of increased plasticity vary across genotypes and environments, indicating the potential for population-level adaptive evolution.

Summary: Birds' aerial hunting behaviors are influenced by flight morphology and ecology, and this study found that gyrfalcons and peregrine falcons exhibit similar attack trajectories guided by a proportional navigation law. However, gyrfalcons operate at lower values of the guidance gain N, resulting in slower turning and longer paths to intercept compared to peregrine falcons. The lower N values in gyrfalcons may not be solely explained by physical constraints, suggesting potential factors such as individual experience or species-level ecological adaptation.

Summary: The behaviors of predators and prey can impact catch success and predation risk, with lone bats being more vulnerable to attacks. The success of hawk attacks is determined by their maneuvers, with high-speed stoops and rolling grabs being more successful. Lone bats are attacked disproportionately often, but hunting efficiency is not decreased by group vigilance or confusion.

Summary: This study examines the swooping trajectories of perching Harris' hawks and finds that they aim to minimize the distance flown after stalling, rather than minimizing time or energy consumption. The findings also suggest a heuristic principle that could guide reinforcement learning of autonomous perching.

Summary: Adaptive plasticity in desert locusts involves changes in social communication and morphological traits according to local population density. High-density adults exhibit yellow warning patterns, with males also yellowing as a signal to deter sexual harassment. These findings highlight the sexual dimension of locust phase polyphenism.

Summary: This study introduces a new Atomic Force Microscopy Force Spectroscopy (AFM-FS) approach to investigate the mechanical properties of taenidia in bush-crickets. The research reveals that resilin significantly affects the mechanical properties of taenidia fibers, and the distribution of elastic modulus is sensitive to the composition and configuration of resilin and chitin. The findings suggest a sophisticated evolution of taenidia fibers with elasticity playing a crucial role in optimization.

Summary: The ears of katydids are pressure-time difference receivers capable of sensitive and accurate directional hearing. The pinnae in katydids do not assist in directional hearing for conspecific call frequencies, but instead act as ultrasound detectors. These findings provide important insights into the evolution of katydid auditory systems and their relationship with predators.
