ABSTRACT
Thus far, ecophysiology research has predominantly been conducted within controlled laboratory-based environments, owing to a mismatch between the recording technologies available for physiological monitoring in wild animals and the suite of behaviours and environments they need to withstand, without unduly affecting subjects. While it is possible to record some physiological variables for free-living animals using animal-attached logging devices, including inertial-measurement, heart-rate and temperature loggers, the field is still in its infancy. In this opinion piece, we review the most important future research directions for advancing the field of 'physiologging' in wild animals, including the technological development that we anticipate will be required, and the fiscal and ethical challenges that must be overcome. Non-invasive, multi-sensor miniature devices are ubiquitous in the world of human health and fitness monitoring, creating invaluable opportunities for animal and human physiologging to drive synergistic advances. We argue that by capitalizing on the research efforts and advancements made in the development of human wearables, it will be possible to design the non-invasive loggers needed by ecophysiologists to collect accurate physiological data from free-ranging animals ethically and with an absolute minimum of impact. In turn, findings have the capacity to foster transformative advances in human health monitoring. Thus, we invite biomedical engineers and researchers to collaborate with the animal-tagging community to drive forward the advancements necessary to realize the full potential of both fields. This article is part of the theme issue 'Measuring physiology in free-living animals (Part II)'.

The human body can be viewed as an organism consisting of a variety of cellular and non-cellular materials interacting in a highly ordered manner. Its complex and hierarchical nature inspires the multi-level recapitulation of the human body in order to gain insights into the inner workings of life. While traditional cell culture models have led to new insights into the cellular microenvironment and biological control in vivo, deeper understanding of biological systems and human pathophysiology requires the development of novel model systems that allow for analysis of complex internal and external interactions within the cellular microenvironment in a more relevant organ context. Engineering organ-on-chip systems offers an unprecedented opportunity to unravel the complex and hierarchical nature of human organs. In this chapter, we first highlight the advances in microfluidic platforms that enable engineering of the cellular microenvironment and the transition from cells-on-chips to organs-on-chips. Then, we introduce the key features of the emerging organs-on-chips and their proof-of-concept applications in biomedical research. We also discuss the challenges and future outlooks of this state-of-the-art technology.

Here we described two activities related to Women in Science: one main conference and one symposium, both developed during the Annual Congress of the Brazilian Physiological Society, which were held within the XXXIII Annual Meeting of the Federation of Brazilian Experimental Biology Societies, from September 3-6, 2018, in Campos do Jordão (SP/Brazil). This conference and the symposium were among the most popular activities of the congress. This is important because the activities addressed important issues, including the fact that only 29% of the worlds' researchers are women, and women have difficulty progressing in a scientific career. Our report discusses why and which strategies could change this reality. We believe this symposium has not only contributed to advance and bring insights to physiological sciences, but, more importantly, it inspired and motivated physiologists to think about gender balance and the contribution and participation of women in physiological science.

This workshop was held at the Teaching Satellite Meeting of the International Union of Physiological Sciences (IUPS), August 5-8, 2017, in Buzios, Rio de Janiero, Brazil. The satellite meeting was attended by physiology educators from across the globe, of whom 34 attended this workshop. The aim of the workshop was to explore how experimental design is taught to students of physiology in different institutions, to consider the aspects that students find challenging, to share good practice, and to think about how experimental design teaching could be improved. Through small-group discussions that were then shared with the whole group, participants were challenged to develop the outline of a research project to investigate a broad topic and then to identify the challenges that students might face if they were given that task. Finally, the group thought about what, in practical terms, could be done to help develop experimental design skills in undergraduates. The outcomes of the discussions are summarized in this report.

Physiology education research aims to investigate teaching-learning aspects and methods specifically applied to physiology teaching and learning. In this paper exploring Brazilian research public data and information from the Brazilian Physiological Society Teaching Committee, we investigated the status of this research topic (physiology education) in Brazil. The data showed that physiology education research needs to be more recognized and supported in Brazil, and more physiologists may become interested in research in this field. Thus this field will become more developed during the physiologists' education.

The aim of the study was to explore the factors associated with the recall of basic medical physiology knowledge among medical interns and to determine the level of retained basic science knowledge. Two hundred and four interns, 114 women and 90 men, working in two major tertiary medical care centers, King Fahad Medical City (KFMC; 29 students) and King Khalid University Hospital (KKUH; 117 students), in Riyadh city, participated in the study. An anonymous knowledge test with 10 validated multiple-choice questions was developed specifically for this purpose. One hundred and forty-six interns (117 working at KKUH and 29 at KFMC) had graduated from medical schools adopting a conventional instructional system, whereas 58 (3 from KKUH and 55 from KFMC had graduated from schools adopting an integrated system (hybrid problem-based learning). Fifty-two students (26%) gained a score ≥60%, whereas 152 students (74%) obtained <60% of the score. Higher scores were associated with younger age ( P < 0.01), traditional curriculum ( P < 0.001), interns from KKUH ( P < 0.001), and candidates for postgraduate studies ( P < 0.02). There was no significant association between recall of physiology knowledge and all other variables studied, including sex. Multivariate analyses show that age and traditional curriculum are the only significant predictors of knowledge retention. Almost three-fourths of the interns scored <60%, and higher scores were significantly associated with younger interns, traditional curriculum, working in KKUH, and interns preparing for graduate studies. However, the difference between the two curricula disappears when the influence of hospital training is considered.

Many professors are interested in providing science outreach to local K-12 students, but may not have the time or resources needed to create an engaging presentation. The American Physiological Society supports outreach initiatives through programs such as the Physiology Understanding (PhUn) Week. Building on these activities, it was desired to create and assess an immersive and engaging Outreach Program in a disadvantaged K-12 student population. Three distinct modules were created on cardiovascular physiology, respiratory physiology, and oral health. All resources for these modules underwent peer review and publication, allowing other professors to easily execute their own outreach programming. The outreach modules were presented to 288 students in 3rd, 5th, 6th, and 7th grade classes. Implementation of the modules resulted in significant increases in student content knowledge, ranging from 32 to 57% improvement ( P < 0.001, dependent t-test), with an average increase of 46%. K-12 science teachers reported that the program was at an appropriate educational level, increased students' enthusiasm for science, and increased students' exposure to science careers. Additionally, the presenters of the Outreach Program were perceived to be enthusiastic, knowledgeable, and proficient at interacting with the students. On open-response survey items, the science teachers indicated a high level of satisfaction with the program and an enthusiasm for continued collaborations. These results indicate the importance of organized and interactive science activities for the success of a new Outreach Program.
