Functional optimality underpins the repeated evolution of the extreme "saber-tooth" morphology.

"Saber teeth"-elongate, blade-like canines-are a classic example of convergence, having evolved repeatedly throughout mammalian history. Within canine teeth, there is a trade-off between the aspects of shape that improve food fracture and those that increase tooth strength. Optimal morphologies strike a balance between these antagonistic functional criteria.

Pilot training for clinical research professionals in using empathy to recognize and respond to implicit bias in research recruitment and retention.

Recruiting and retaining research participants is challenging because it often requires overcoming structural barriers and addressing how histories of mistrust and individuals' lived experiences affect their research engagement. We describe a pilot workshop designed to educate clinical research professionals on using empathy skills to recognize and mitigate bias to improve recruitment and retention. In a post-workshop survey (22/31 participants completed), 94% agreed the workshop helped them practice perspective-taking, recognize implicit bias, and identify opportunities for empathy.

Community knowledge of Australia's national preventive health strategy focus areas: a nationally representative survey of 1509 adults.

Background: While some general patterns and trends of health information seeking and literacy in the Australian population are known, there is a need to understand these behaviours and skills specific to the focus areas outlined in the National Preventive Health Strategy (NPHS).

Methods: In response, this study employed a cross-sectional online survey of adults in the Australian general population (n = 1509) to investigate their knowledge and health information seeking behaviour regarding the NPHS' seven focus areas. It also explored primary care practitioners as a preventive health information source.

Machine learning and molecular docking prediction of potential inhibitors against dengue virus.

Introduction: Dengue Fever continues to pose a global threat due to the widespread distribution of its vector mosquitoes, and . While the WHO-approved vaccine, Dengvaxia, and antiviral treatments like Balapiravir and Celgosivir are available, challenges such as drug resistance, reduced efficacy, and high treatment costs persist. This study aims to identify novel potential inhibitors of the Dengue virus (DENV) using an integrative drug discovery approach encompassing machine learning and molecular docking techniques.

Fox Insight: Most Bothersome Symptoms in Early-Stage Parkinson's Disease.

Background: Limited evidence exists regarding the meaningfulness of symptoms experienced in early Parkinson's disease (PD).

Objectives: To identify the most bothersome symptoms experienced by people with early PD, leveraging data from the Parkinson's Disease Patient Report of Problems (PD-PROP) questionnaire within the Fox Insight Study.

Methods: Individuals with a self-reported diagnosis of PD completed the PD-PROP questionnaire, reporting up to five most bothersome symptoms.
