User innovation: a novel framework for studying animal innovation within a comparative context

Specific Effects of Characteristics of Enriched Environment on Innovative Problem Solving by Animals

Numerous studies have revealed that an enriched environment can enhance the survival-related behaviors and brain functions of animals. However, the effects and specific roles of the enrichment characteristics on animals' innovative capability, a cognitive ability crucial for survival in nature, are still not well known. In this study, we assigned mice to environment-manipulation groups (n = 15 each) to investigate the specific effects of environmental novelty (novel vs. familiar) and environmental complexity (complex vs. normal) on innovative problem solving and its possible neural mechanisms. Results showed that mice in only the novel-environment group performed better at innovative-problem-solving tasks and showed greater numbers of novel explorations and dopaminergic projections from the ventral tegmental area to the nucleus accumbens in the brain. These findings indicate that an enriched environment has the potential to promote the innovative capability of mice by enhancing their novel exploratory motivation, which depends on the novelty of the environment but not its complexity.

Surgical innovation in LMICs-The perspective from India

Surgical Innovations are central to surgical progress, and have led to exponential growth in various fields of Surgery. Surgical Innovations in Lower and Middle Income Countries are the result of creativity of frontline health workers in search of simple, safe and ethical solutions for their unique challenges. The key lies in: 'simplifying the idea/technique/device' to find patients' needs-driven low-cost innovative surgical solutions; which can be used on a wider scale to achieve health equity for underserved populations. Local surgeons understand the difficulties and nuances of various problems and can provide local-evidence-based customized solutions for their patients' health problems. We developed a Surgical Innovation Ecosystem allowing us to see difficulties as opportunities, learn from everyone and conduct research on what is 'important' rather than what is 'interesting'. Barriers to Surgical Innovations in Lower and Middle Income Countries are well known; however, a roadmap to overcome these barriers is now available. The right balance has to be found between encouraging creativity and innovation while maintaining ethical awareness and responsibility to patients. Introduction and adoption of Surgical Innovations are governed by evidence-based principles and have to undergo a rigorous and scientific evaluation. Science of Surgical Innovations has finally come of age and is getting its due recognition and the pioneering innovators are receiving the much needed appreciation and support.

Leveraging Social Learning to Enhance Captive Animal Care and Welfare

From ants to zebras, animals are influenced by the behavior of others. At the simplest level, social support can reduce neophobia, increasing animals’ exploration of novel spaces, foods, and other environmental stimuli. Animals can also learn new skills more quickly and more readily after observing others perform them. How then can we apply animals’ proclivity to socially learn to enhance their care and welfare in captive settings? Here, I review the ways in which animals (selectively) use social information, and propose tactics for leveraging that to refine the behavioral management of captive animals: to enhance socialization techniques, enrichment strategies, and training outcomes. It is also important to consider, however, that social learning does not always promote the uniform expression of new behaviors. There are differences in animals’ likelihood to seek out or use socially provided information, driven by characteristics such as species, rank, age, and personality. Additionally, social learning can result in inexact transmission or the transmission of undesirable behaviors. Thus, understanding when, how, and why animals use social information is key to developing effective strategies to improve how we care for animals across settings and, ultimately, enhance captive animal welfare.
