Developing a culture of safety in biomedical research training

The National Institute of General Medical Sciences (NIGMS) at the U.S. National Institutes of Health (NIH) is committed to supporting the safety of the nation’s biomedical research and training environments. Institutional training grants affect many trainees and can have a broad influence across their parent institutions, making them good starting points for our initial efforts to promote the development and maintenance of robust cultures of safety at U.S. academic institutions. In this Perspective, we focus on laboratory safety, although many of the strategies we describe for improving laboratory safety are also applicable to other forms of safety including the prevention of harassment, intimidation, and discrimination. We frame the problem of laboratory safety using a number of recent examples of tragic accidents, highlight some of the lessons that have been learned from these and other events, discuss what NIGMS is doing to address problems related to laboratory safety, and outline steps that institutions can take to improve their safety cultures.

All new funding opportunity announcements (FOAs) for training programs supported by the National Institute of General Medical Sciences (NIGMS) contain the expectation that the programs will promote “inclusive, safe and supportive scientific and training environments.” In this context, the word “safe” refers to several aspects of safety. First, we mean an environment free from harassment and intimidation, in which everyone participating is treated in a respectful and supportive manner, optimized for productive learning and research. We also mean that institutions should ensure that their campuses are as safe as possible so that individuals can focus on their studies and research. Finally, we mean safety in the laboratory and clinical spaces. In this Perspective, we focus on this last issue and describe some of the approaches NIGMS is taking to help the biomedical research community move toward an enhanced culture of safety in which core values and the behaviors of leadership, principal investigators (PIs), research staff, and trainees emphasize safety over competing goals.     

From dusk till dawn: camera traps reveal the diel patterns of flower feeding by hawkmoths

1. Diel rhythms of foraging activity by animal flower visitors can reflect niche partitioning and are considered an important component of selection on floral traits. However, it has been notoriously difficult to obtain objective information on the patterns of flower visitation by crepuscular and nocturnal insects. 2. Motion-activated cameras were used for field-based studies of hawkmoth foraging behaviour on six African plant species. 3. The results showed that short-tongued hawkmoth species forage mainly around dusk and then sporadically throughout the night, whereas long-tongued hawkmoth species feed consistently throughout the night, with a peak shortly before midnight. 4. These results provide the first quantitative estimates of diel patterns of interactions between multiple hawkmoth and plant species and, when combined with qualitative reports from other studies, suggest that differences in diel activity between the two main hawkmoth functional groups (short- and long-tongued) are consistent across the Old and New Worlds.     

Proximate and ultimate causes of reproductive suppression among female yellow baboons at Mikumi National Park,Tanzania

Attack coalitions, whereby two or more individuals attack another animal simultaneously, were studied in 53 sexually mature female baboons from one small and two large troops at Mikumi National Park, Tanzania. For 14 months, three observers recorded coalition behavior throughout the day, using focal group sampling on a behavior-dependent basis. Coalition rates were considerably greater in the two large troops than in the small troop, and primarily involved natal females rather than males. Coalition frequencies corresponded closely to measures of reproductive synchrony, both within and between troops. Involvement in attack coalition behavior depended on the reproductive states and ranks of both attackers and recipients. The first few females to give birth in the cohort received particularly high amounts of coalition aggression just before and immediately after giving birth. Receipt of attack coalitions was significantly associated with an increased number of cycles to conception and longer interbirth intervals, as well spontaneous abortion, premature birth, and prolonged gestation. A parallel study on survivorship patterns of immature baboons at Mikumi provided evidence for ultimate cause of the observed coalition patterns. These combined results suggest that attack coalition behavior is a form of reproductive competition whereby females attempt to suppress the reproduction of others at predictably competitive times and thereby reduce the competition their own infants face from the time they are weaned.
