Author summary During development, cells can have many fates, one of which is to deliberately die. If a cell’s inherent ability to die is lost, unwanted cells remain, which can lead to pathologies such as abnormal brain development or cancer. Dead cell remains must also be fully and efficiently cleared away by being ingested and digested by other cells, to avoid autoimmunity. Cells that are destined to die, like any cell, can also be subject to stress, which can change cell behavior. Moreover, cells fated to die often have highly intricate shapes, such as nerve cells in the brain, and their removal may entail different strategies for different regions of the cell. In this study, we have used the pre-destined “3-in-1” death of a structurally-complex cell in the roundworm C. elegans as a platform to describe the genetics behind how one cell bolsters its inherent ability to consume an area of another dying cell by mounting a response to environmental stress. Specifically, we report, to ou

The urge to move to music, often referred to as groove, is influenced by various factors, including familiarity with the music. The influence of nostalgia, which involves familiarity but also includes pleasant, sad, and wistful emotions, remains largely unexplored. Here we investigate the impact of both familiarity and nostalgia on the desire to tap, move, and dance along to music. To evoke nostalgia, we selected popular songs from the participants’ adolescent years. More recent songs served as a low-nostalgia but familiar control. Participants completed an online experiment, rating songs based on their desire for three different movement types (tap, move, and dance), as well as enjoyment, familiarity, and nostalgia. Nostalgic songs elicited higher desire to move than familiar songs across all three movement categories. Additionally, both familiarity and nostalgia predicted move and tap ratings, but only nostalgia emerged as a predictor for dance ratings. Our results suggest a distinct

The term “good motor skill” is often discussed in everyday contexts and when observing sports; however, its definition remains elusive, and the associated factors are not well understood. Therefore, in this cross-sectional study, we investigated the determinants of subjective total athletic ability, defined as the sum of subjective athletic abilities across 11 sports disciplines. A sample of 406 undergraduate students completed a questionnaire to evaluate their perceived athletic prowess in various sports, as well as assessments of their personality traits, family background, and sports performance. The analysis revealed correlations between the perceived general athletic ability and specific abilities in soccer, volleyball, basketball, and short-distance racing. Furthermore, linear model analyses indicated a positive association between perceived total athletic ability and personal characteristics such as grit, resilience, and a growth mindset. Factors such as recreational activities

People all around the world live with cats and cats engage in many social behaviors toward their owners. Olfaction is one of the most important sensory abilities in cats, yet its role in recognizing humans remains unclear. In this study, we assessed the role and characteristics of olfaction in the discrimination of known or unknown humans by cats using ethological methods. Whether cats exhibit a lateralization of nostril use in response to a variety of olfactory stimuli, exposure experience, inter alia, was investigated. Cats were simultaneously presented with three odor stimuli: that of a known person (owner), an unknown person, and a blank control. Responses to the cat 2 scale (Feline Five) and the cat–owner relationship scale (CORS) were collected from cat owners through questionnaires. It was observed that cats spent a substantially longer time sniffing the odor of an unknown person than that of a known person, indicating the use of their sense of smell to distinguish between heter
