AI Article Synopsis
- Collective movements in animal societies require consensus among members, but this is complicated by individual behavioral differences, or 'personality.'
- The study uses a theoretical approach to assess how personality and feedback contribute to collective movement decisions, finding that personality can significantly shape these decisions.
- Results indicate that as differences in personality become more pronounced, their influence on collective behavior increases, suggesting that personality plays a crucial role alongside feedback in animal group dynamics.
Article Abstract
Collective movements are essential for the effective function of animal societies, but are complicated by the need for consensus among group members. Consensus is typically assumed to arise via feedback mechanisms, but this ignores inter-individual variation in behavioural tendency ('personality'), which is known to underpin the successful function of many complex societies. In this study, we use a theoretical approach to examine the relative importance of personality and feedback in the emergence of collective movement decisions in animal groups. Our results show that variation in personality dramatically influences collective decisions and can partially or completely replace feedback depending on the directionality of relationships among individuals. The influence of personality increases with the exaggeration of differences among individuals. While it is likely that both feedback and personality interact in nature, our findings highlight the potential importance of personality in driving collective processes.

Usefulness of subtraction thermography in the evaluation of blood vessels and lymphatic vessels in the dental pulp.
Acta Bioeng Biomech

: Caries or iatrogenic thermal trauma of the teeth have a significant impact on the dental pulp structure connected with stimulation of angiogenesis and lymphangiogenesis. Therefore, the aim of the study was to identify the difference in the rate of heat dissipation by vessels present in the dental pulp. : Freshly extracted healthy ( = 10) and carious ( = 14) molars and premolars were cut on a diamond saw and subjected to active thermographic examination and then subjected to lymphoscintigraphy and X-ray examination.

Purpose: Considerable genetic heterogeneity is currently thought to underlie hereditary prostate cancer (HPC). Most families meeting criteria for HPC cannot be attributed to currently known pathogenic variants.
Methods: To discover pathogenic variants predisposing to prostate cancer, we conducted a familial case-control association study using both genome-wide single-allele and identity-by-descent analytic approaches.
Exploring the clinical, psychological, and social relevance of menopause for trans and gender diverse people: a qualitative study.
Menopause
January 2025
From the Department of General Practice, Monash University, Melbourne, Australia.
Objective: The aim of this study was to explore the meanings and experiences of menopause for trans and gender diverse (TGD) people and how menopause affects clinical practice.
Methods: For this qualitative study in 2021-2022, a scoping literature review informed interview schedule development. Following email invitations, online semi-structured interviews were conducted in March-April 2021 in Australia with three prominent TGD community leaders (trans male, trans female, nonbinary person) and three experienced medical practitioners (general practitioner, endocrinologist, psychiatrist), which were audio-recorded and transcribed.

Objective: Aim: To evaluate the expression levels of SOX-10 in tissues of bladder tumor and to prove the correlation between SOX-10 expression and clinicopathological characteristics of bladder tumors, including patient age, sex, tumor grade, and muscle invasion.
Patients And Methods: Materials and Methods: Forty formalin fixed paraffin embedded FFPE tissue blocks gathered by transurethral resection of bladder tumor are collected from teaching hospitals at Al-Najaf governorate. Those blocks were stained by hematoxylin and eosin.
Measurement of inferior colliculus volume based on MRI image stacks and its relationship with age and hearing status.
PLoS One
January 2025
Department of Otolaryngology, University Hospital Regensburg, Regensburg, Germany.
The inferior colliculus is a key nucleus in the central auditory pathway, integrating acoustic stimuli from both cochleae and playing a crucial role in sound localization. It undergoes functional and structural development in childhood and experiences age-related degeneration later in life, contributing to the progression of age-related hearing loss. This study aims at finding out, whether the volume of the human inferior colliculus can be determined by analysis of routinely performed MRIs and whether there is any age-related variation.
