AI Article Synopsis
- The text discusses the persistence of cooperative behavior in populations where individuals might benefit more from acting selfishly (defecting) rather than cooperating.
- It highlights the role of interdependent networks and evolutionary game dynamics in maintaining cooperation, even among well-mixed populations.
- The findings suggest potential mechanisms for fostering cooperation, which could have applications in both biological and social contexts.
Article Abstract
Although several mechanisms can promote cooperative behavior, there is no general consensus about why cooperation survives when the most profitable action for an individual is to defect, especially when the population is well mixed. Here we show that when a replicator such as evolutionary game dynamics takes place on interdependent networks, cooperative behavior is fixed on the system. Remarkably, we analytically and numerically show that this is even the case for well-mixed populations. Our results open the path to mechanisms able to sustain cooperation and can provide hints for controlling its rise and fall in a variety of biological and social systems.

Background: Distal myopathies (MPDs) are heterogeneous diseases of complex diagnosis whose prevalence and distribution in specific populations are unknown.
Methods: Demographic, clinical, genetic, neurophysiological, histopathological and muscle imaging characteristics of a MPDs cohort from a neuromuscular reference center were analyzed to study their epidemiology, features, genetic distribution and factors related to diagnosis.
Results: The series included 219 patients (61% were men, 94% Spanish and 41% sporadic cases).
Taking a partnership approach to embed physical activity in local policy and practice: a Bradford District case study.

Background: Supportive policy is an important component of a whole-systems approach to increasing physical activity and reducing inequalities. There is a growing body of literature surrounding the design and effectiveness of national policy approaches to physical activity, but evidence related to local-level approaches is lacking. The aim of this study was to examine 'what works', and identify factors underpinning change, focused on work to embed physical activity in local policy and practice in Bradford, UK.

Serpentine microstructures offer excellent physical properties, making them highly promising in applications in stretchable electronics and tissue engineering. However, existing fabrication methods, such as electrospinning and lithography, face significant challenges in producing microscale serpentine structures that are cost-effective, efficient, and controllable. These methods often struggle with achieving precise control over fiber morphology and scalability.

We study the emergence of agency from scratch by using Large Language Model (LLM)-based agents. In previous studies of LLM-based agents, each agent's characteristics, including personality and memory, have traditionally been predefined. We focused on how individuality, such as behavior, personality, and memory, can be differentiated from an undifferentiated state.

Cooperation and competition in social interaction are important to social development. There are many studies examining the neural mechanism underlying these behaviors; however, little is known about the potential role of payoff norms in social interactions. This study introduced two distinct payoff norms: zero-sum (ZS) and non-zero-sum (NZS).
