Summary: Regeneration is a widespread phenomenon in the animal kingdom, but the distribution patterns and key factors influencing regeneration capabilities are still not well understood. In this study, the regeneration process of leg appendotomy in a sea spider was carefully observed, revealing high regeneration capabilities and similarities to normal ontogenetic morphogenesis.

Summary: Regenerative abilities vary greatly among different animal lineages. In this study, researchers discovered that immatures of the sea spider Pycnogonum litorale can regrow almost complete body segments and tissues, including the hindgut and musculature, after transverse amputation. This challenges the commonly held belief that molting animals are incapable of primary body axis regeneration, suggesting that the ability for regeneration may have been inherited from a protostome ancestor.

Summary: The rise of arthropods in different ecosystems has significantly impacted ecological networks. Recent discoveries of well-preserved Palaeozoic fossils have shed light on the appearance of extant arthropods during the Cambrian explosion and the role of plankton and hard integuments in their diversification. The understanding of arthropod evolution has been altered, and important questions have been raised, such as cephalic plasticity and the development of specialized appendages for suspension-feeding.

Summary: Using a straight-line generating mechanism for a walking robot leg provides advantages such as energy efficiency and simplicity of control system compared to traditional bio-inspired leg designs. A six-link mechanism based on the design of lambda-type mechanism was proposed as a walking robot propeller, allowing for unlimited foot adaptation and a new analytical method of mechanism synthesis based on least square approximation was developed. This method avoids branching defect and improves transmission angle, resulting in higher efficiency and a walking robot with optimal leg design achieved through multicriteria optimization.

Summary: Due to scaling issues, the importance of passive muscle and joint forces increases as limb size decreases. The resting-state range of passive forces is predicted to correlate with the limb's typical working range in locomotion, which could simplify motor control and save energy. This study provides evidence of how evolution can alter behavior by changing passive muscle and joint properties.

Summary: Sponges are early-branching animals with a simple body plan but a complex genetic repertoire. The continuity between larval cells and adult tissues is still not well understood. This study identified a novel protein, ilborin, which is present in multiple species and may be involved in calcium-mediated regulation of energy metabolism.

Summary: Legged locomotion is crucial for the mating and survival of terrestrial animals. Insects have proprioceptive chordotonal organs that encode relative movement between segments. The femoral chordotonal organ (fCO) in Drosophila melanogaster consists of neurons with different encoding properties, and has been shown to contribute to interleg coordination and walking behavior. However, the exact roles of different subsets of fCO neurons have not been investigated. This study used optogenetic inhibition to demonstrate that a subset of fCO neurons replicates the effects of inhibiting the whole fCO, but individual subset types do not strongly affect single-leg kinematics. fCO subsets also seem to play a minor role in interleg temporal coordination. Future studies should further explore the functional classification of fCO neurons based on anatomy and encoding properties.

Summary: The main challenge in reinstating human-like locomotion using robotic prosthetics, orthotics or exoskeletons is coordinating their motion with that of the biological limbs. In this study, a nonlinear auto-regressive model with exogenous inputs was used to continuously estimate ankle, knee and hip moments. The best performance was observed when ankle moments were estimated from shank angles, while the weakest performance was when knee moments were estimated using thigh angles.

Summary: A new small euarthropod, Astutuscaris bispinifer gen. et sp. nov., has been discovered in the early Cambrian Stage 4 Guanshan Biota in Yunnan, China. This euarthropod possesses unique features, such as a wide head shield, possible eyes, and paired frontalmost appendages. The discovery expands the biological diversity of euarthropods in the Guanshan Biota.

Summary: The study showed that in insects with disrupted neural information transfer through one connective, temporal inter-leg coordination was significantly reduced, but compensatory changes in spatial coordination occurred if they experienced naturalistic load distribution. While mechanical load transfer could not compensate for lesion-induced effects on temporal inter-leg coordination, significant shifts in touch-down and lift-off positions among legs were observed in free walking insects with disrupted neural information transfer.

Summary: This study analyzed the effects of pile leg insertion depth and soil shear strength gradient on the bearing capacity of pile leg-mat foundation. The results showed that the pile leg insertion depth significantly enhanced the horizontal bearing capacity of the foundation, while the improvement on vertical and moment bearing capacity was not significant.

Summary: The study found that when one leg is constrained, people may prefer to adopt an asymmetric gait to minimize metabolic power, rather than maintaining bilateral symmetry. This asymmetric walking pattern may be more energy-efficient, especially when the constraint is large.

Summary: This study presents a new type of high-valence metal modified selenospinels as large-current-density oxygen evolution reaction (OER) catalysts. The optimized Mn-CuCo2Se4 catalyst exhibits prominent OER activity and stability in alkaline media, with a high mass activity and turnover frequency. In situ X-ray absorption spectroscopies reveal the formation of a surface active layer during the OER, responsible for the highly-active large-current-density activity.

Summary: This study utilized multiple molecular data categories to resolve the phylogenetic relationships of sea spiders, revealing their basal topology and including families that were not fully sampled before. In addition, molecular divergence time estimation confirmed the Ordovician origin of crown group sea spiders, showing that in the evolutionary process sea spiders exhibit greater resilience to mass extinction episodes compared to mollusk and echinoderm lineages.

Summary: Deciphering the evolutionary relationships of Chelicerata has been challenging due to their ancient rapid radiation and elevated evolutionary rates in some lineages. Despite conflicting hypotheses, the monophyly of Arachnida is widely accepted. However, our analysis of high-quality genomic and transcriptomic data suggests the nested placement of horseshoe crabs within a paraphyletic Arachnida. We found that genes and sites that recover arachnid monophyly are noisy and have low information content. Additionally, combined analysis of morphological and molecular data supports the placement of merostomates within Arachnida, indicating convergence driven by terrestrial adaptations.
