Summary: Crickets are able to use polarized light information to find a target place, with time and walking distance significantly decreased with increasing trials. The fixed arrangement of the e-vector pattern and cool spot helps crickets locate the target place faster, while random rotation of the e-vector pattern does not provide assistance.

Summary: This paper proposes a novel navigation and control method for underwater vehicles that can navigate autonomously without relying on satellites. The method is based on underwater polarization patterns, and includes an algorithm for measuring underwater course angles and the development of underwater polarization detection equipment. By combining polarization and inertial information, a strapdown navigation method is developed for a Remote Operated Vehicle (ROV). The feasibility of angle measurement based on polarization is verified in water tank experiments, and the underwater navigation accuracy is evaluated in a real underwater environment. The results show that the proposed method can effectively improve the efficiency and accuracy of ROV underwater work.

Summary: Processionary caterpillars of Thaumetopoea pityocampa in Europe and Ochrogaster lunifer in Australia form single files of larvae crawling head-to-tail guided by polarization vision, with anatomical specialization in the first stemma. Behavioral and anatomical evidence suggest that polarized light cues are important for larval orientation and can be robustly detected with a simple visual system.

Summary: In this study, a navigation method based on the integration of SINS/PNS/OD is proposed to address the limitations of GPS in satellite-denied or unstructured environments. Real-time estimation of the angle of polarization error is utilized to improve the accuracy of the navigation model. An adaptive anti-disturbance navigation method is designed to mitigate the outliers in polarization measurement caused by shelter, cloud, or large maneuvers. Experimental results demonstrate that the proposed method outperforms existing methods in heading estimation under large maneuvers.

Summary: This paper proposes an artificial neural network, PLSPD, for polarized light solar position determination. The network determines both the solar azimuth angle and the solar elevation angle by redesigning the encoding method for the solar elevation angle. Experimental results show that PLSPD can accurately determine both angles and achieves higher accuracy in solar azimuth angle determination compared to PLOD.

Summary: This paper proposes a brain-inspired navigation model based on absolute heading for the autonomous navigation of unmanned platforms. The model combines the strategy of acquiring absolute heading from the sky environment and the brain-inspired navigation system, resembling the navigation mechanism of migratory animals. It constructs a grid cell network model and a head-direction cell network model based on the continuous attractor network (CAN), creates an absolute heading-based environmental vision template using line scan intensity distribution curve, and corrects the path integration error using the template. A topological cognitive node is constructed based on grid cell, head direction cell, environmental visual template, absolute heading information, and position information. The experimental results demonstrate the superiority of the proposed model in terms of visual template recognition accuracy, accuracy, and topology consistency of the constructed environment topology map.

Summary: This paper explores the feasibility of underwater polarization navigation technology in low visibility waters, specifically at large depths. Through the establishment of a coupled atmosphere-surface-underwater optical transmission model, underwater polarization patterns at different depths are simulated. Underwater experiments and simulations are conducted to understand the effects of depth and other environmental factors on underwater polarization navigation technology. The study provides theoretical references for the application of underwater polarization navigation and improves the theory of polarization transmission.

Summary: A novel class of green-sensitive photoreceptors, G+R- cells, have been discovered in butterflies, showing hyperpolarizing responses to red light and interacting with red opponent units R9. This mechanism has been found in various butterfly species, suggesting the potential for tetrachromacy in their visual systems.

Summary: This study investigated the effect of polarized light on host foraging by stable flies. The results showed that stable flies prefer to alight on horizontally polarized stimuli with a high degree of linear polarization, and this preference disappeared when ultraviolet (UV) or human-visible wavelengths were omitted. Further experiments revealed that the combination of UV and blue wavelength bands was sufficient for the flies to discriminate polarized light. These findings contribute to our understanding of polarization vision and foraging behavior among blood-feeding insects and have implications for trap design.

Summary: The brains of some insects have the ability to encode and decode polarization information and obtain heading angle information. This study proposes new decoding methods, including average value decoding and weighted average value decoding, to use the heading information contained in multiple neurons for heading determination. Furthermore, threshold value decoding and weighted threshold value decoding are proposed to eliminate interference from neurons with low activation. The study also suggests improving the heading determination accuracy of the artificial neural network through pre-training.

Summary: Research using fruit flies as a model species shows that insect dispersal behavior can be influenced by wind under specific conditions. Through release-and-recapture experiments, it was observed that even tiny fruit flies could disperse tens of kilometers in light winds. An agent-based model explains the specific behaviors of fruit flies during dispersal, depicting a balance between covering large distances while intercepting odor plumes from upwind sources.

Summary: When animals move, their brains receive information about the body's velocity and heading, which must be transformed into world-centric coordinates for navigation. In the fruit fly brain's fan-shaped body, two cell types jointly encode translational velocity and heading as the fly walks, aiding in path integration during movement.

Summary: In this study, it was found that stabilization reflexes during fly flight are implemented by a proportional-integral (PI) controller. The b1 and b2 motor units of the fly's steering muscle system were identified to modulate the angular displacement and angular velocity, respectively. This finding reveals the organizational principle of muscles in flight control in insects.
