Summary: For social insects, allocating foraging workers to the best patches is a crucial task that different insect species solve in various ways. Bumblebees combine individual exploration with social information to make decisions during foraging, which has been found to be advantageous in obtaining better resources. This study provides insights into the collective foraging strategy of bumblebees, highlighting the importance of social modulation of individual decisions in evolutionary biology.

Summary: In this study, the researchers combined experimental analyses with theoretical modeling to investigate how animal groups modulate their investment into tasks under uncertain conditions. They found that weaver ants cap their investment into chains and do not form complete chains when the gap is taller than 90 mm. The ants budget the time they spend in chains based on their distance to the ground, and a distance-based model of chain formation explains this tradeoff without invoking complex cognition.

Summary: Proximity social interactions are crucial for infectious diseases transmission. Locations like transportation hubs are characterized by constant in and out flow of people. Using anonymized individuals' trajectories data, the authors analyze London Heathrow's role as a potential superspreader and propose a spatial immunization policy to reduce disease spreading risk.

Summary: The softening of interaction of active particles destabilizes the highly ordered dense phase, resulting in the formation of a porous cluster spanning the system. The system also exhibits standard percolation transition characteristics when the particle motility exceeds a critical value. Additionally, similar transitions are observed in the athermal limit, even at low motility. The phase diagram of repulsive active particles is revealed to be richer than previously conceived.

Summary: This study systematically investigates the impact of a group's spatial structure, density, polarization and aspect ratio of physical bodies on static visual interaction networks, revealing fundamental differences in information spreading compared to other interaction models. The findings could have implications for the study of animal groups and the construction of robotic swarms communicating via vision.

Summary: The study utilized data from hospitals to simulate the transmission risk of healthcare-associated infections in different spatial units and healthcare workers' occupations. Findings show that inpatient care and public areas are the riskiest categories, and nurses are at greater risk of infection.

Summary: The global spread of COVID-19 pandemic is influenced by the infectivity of the virus, human travel patterns, and mitigation measures. Spatial correlations of new active cases in different time periods were analyzed at the county level in the USA. The results showed that the epidemic did not progress uniformly and the length of correlation varied significantly. Travel between cities played a significant role in long-range spreading, particularly during the initial months of the epidemic. The presence of percolation transitions in November 2020 and January 2021 corresponded to the peak of the epidemic in the country.

Summary: Army ant mass raiding evolved from group raiding as colony size expanded. Experimental evidence shows that mass raiding gradually emerges from group raiding without altering individual behavioral rules.

Summary: This study visualizes the spatial spreading of a dense ensemble of spin cyclotron magnetoexcitons in a quantum Hall insulator at filling factor nu = 2 using an optical system with a high aperture ratio. It is found that non-diffusive propagation is not only characteristic of excitons with a momentum on the order of the reciprocal magnetic length, but also of excitons with very low momenta. The non-diffusive propagation of magnetoexciton condensates in real space is accompanied by a huge threshold increase in the amplitude of light reflection from excitations. The possible explanations of the observed behavior are discussed.

Summary: This study reveals two different processes in the diffusive epidemic process, namely the subdiffusive propagation of infection clusters and the diffusive fluctuations in the healthy population. It sheds new light on the theoretical classification of the system.

Summary: This study investigates the movement of aerosolized viruses in a dense urban area in London, focusing on the spread and decay of COVID-19 from a hospital and railway stations. The findings suggest that virus concentration decreases rapidly near sources, but can travel up to hundreds of meters under certain meteorological conditions. The study emphasizes the importance of using face coverings in high-risk areas to reduce infection rates.

Summary: We present a mechanical design rule that enables robots to operate in a collision-dominated environment. By encoding a reorientation response to external forces in a three-dimensional printed exoskeleton, we enhance the motility and stability of individual robots and leverage steric interactions for collective behavior. This mechanical layer adds to the robot's sense-act cycle at the swarm level and promotes information flow for online distributed learning.

Summary: The heterogenous magma supply at ultraslow spreading ridges creates diverse seafloor morphologies and lithospheric structures, which lead to a large variability in marine magnetic anomalies. On the other hand, different magnetic signatures of different seafloors provide an opportunity to identify the modes of seafloor spreading on the ultraslow spreading ridges.

Summary: This study introduces a new vision-based model based on the OODA framework, which addresses the challenges of capturing inter-individual differences and achieving adaptive responses. The experiment demonstrates that the proposed alignment response shortens the consensus time of the group and the adaptive mechanism enhances the response capability.

Summary: In this study, collision experimentation was used to investigate the spatial and temporal variation of droplets on a target particle surface. Image processing was employed to capture the microscopic and evolutionary features of droplets. Theoretical analysis revealed the relationship between the dimensionless liquid film thickness and spreading area, and the influence of Weber and Reynolds numbers on the dynamic contact angle was also examined.
