Rubble pile asteroids are widely understood to be composed of reaccumulated debris following a catastrophic collision between asteroids in the main asteroid belt, where each disruption can make a family of new asteroids. Near-Earth asteroids Ryugu and Bennu have been linked to collisional families in the main asteroid belt, but surface age analyses of each asteroid suggest these bodies are substantially younger than their putative families. Here we show, through a coupled collisional and dynamical evolution of members of these families, that neither asteroid was likely to have been created at the same time as the original family breakups, but rather are likely remnants of later disruptions of original family members, making them second, or later, generation remnants.

Background: Medical educational societies have emphasized the inclusion of marginalized populations, including the lesbian, gay, bisexual, transgender and queer (LGBTQ+) population, in educational curricula. Lack of inclusion can contribute to health inequality and mistreatment due to unconscious bias. Little didactic time is spent on the care of LGBTQ+ individuals in emergency medicine (EM) curricula.

Background: At the conclusion of residency candidate interview days, faculty interviewers commonly meet as a group to reach conclusions about candidate evaluations based on shared information. These conclusions ultimately translate into rank list position for The Residency Match. The primary objective is to determine if the post-interview discussion influences the final scores assigned by each interviewer, and to investigate whether interviewer characteristics are significantly associated with the likelihood of changing their score.

Background: More than 90% of pediatric patients presenting to emergency departments (EDs) in the United States are evaluated and treated in community-based EDs. Recent evidence suggests that mortality outcomes may be worse for critically ill pediatric patients treated at community EDs. The disparate mortality outcomes may be due to inconsistency in pediatric-specific education provided to emergency medicine (EM) trainees during residency training.

Article Synopsis
  • * A survey of EM program directors revealed that 84% collect nursing feedback, viewing it as beneficial for evaluating professionalism and communication skills, though many believe it has little effect on residency progression.
  • * Challenges related to data collection, the quality of feedback, and potential bias were identified, indicating a need for more consistent methods in gathering nursing assessments in EM.
