Symmetry is an important concept in biology, being related to mate selection strategies, health, and survival of species. In human faces, the relevance of left-right symmetry to attractiveness and health is not well understood. We compared the appearance of facial attractiveness, health, and symmetry in three separate experiments. Participants inspected front views of faces on the computer screen and judged them on a 5-point scale according to their attractiveness in Experiment 1, health in Experiment 2, and symmetry in Experiment 3. We found that symmetry and attractiveness were not strongly related in faces of women or men while health and symmetry were related. There was a significant difference between attractiveness and symmetry judgments but not between health and symmetry judgments. Moreover, there was a significant difference between attractiveness and health. Facial symmetry may be critical for the appearance of health but it does not seem to be critical for the appearance of attractiveness, not surprisingly perhaps because human faces together with the human brain have been shaped by adaptive evolution to be naturally asymmetrical.

Background: Bicycle messengers in the online food delivery sector typically work on an on-demand basis, have digitally mediated relationships with their employer, and have very limited labor rights. In this study, we explore how bicycle messengers themselves experience their workday and how platform work influences their identity and wellbeing.
Method: We conducted qualitative interviews with ten bicycle messengers working for Foodora and Wolt in Bergen and Oslo, Norway.

The functional organization of the human object vision pathway distinguishes between animate and inanimate objects. To understand animacy perception, we explore the case of zoomorphic objects resembling animals. While the perception of these objects as animal-like seems obvious to humans, such "Animal bias" is a striking discrepancy between the human brain and deep neural networks (DNNs).

This study explores the multifaceted challenges experienced by individuals with schizophrenia during extreme heat, highlighting the interplay between individual factors, social dynamics, and environmental influences. Despite making up only 1% of the Canadian population, individuals diagnosed with schizophrenia comprised 16% (n = 97) of the deaths during the 2021 heat dome in Western Canada. However, to date, there exists scant qualitative research that explore the direct experiences and the intricacies of intersecting factors faced by individuals with schizophrenia during extreme heat events.

Objectives: Cervical cancer is the most prevalent cancer in Uganda, posing a significant burden with high mortality rates. Early detection through screening is crucial to reduce cervical cancer mortality. This study aimed to investigate the awareness, knowledge, and attitudes toward cervical cancer and its screening among residents in the central and western regions of Uganda.

T-cell lymphomas represent non-Hodgkin lymphomas distinguished by the uncontrolled proliferation of malignant T lymphocytes. Classifying these neoplasms and the ongoing investigation of their underlying biological mechanisms remains challenging. Significant subtypes encompass peripheral T-cell lymphomas, anaplastic large-cell lymphomas, cutaneous T-cell lymphomas, and adult T-cell leukemia/lymphoma.
