On the size of apical foramen in anterior teeth, bicuspids and molars [PDF]
, 2020 The present authors have used a replica method to obtain area size measurements for the apical foramen in 4,613 human permanent teeth, and have obtained the following results:1.

Journal of the Royal Anthropological Institute, EarlyView.The year 2025 marked the ninetieth since a fossil hominin occipital bone was discovered in Swanscombe, southeast England. In subsequent years, its parietal bones were found, producing what remains the oldest partial cranium from Britain today. In the earliest analyses, it was interpreted as a descendant of the infamous fraudulent fossil Piltdown Man ...

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior
Integrative Zoology, EarlyView.Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.

A New Model of Feeding Biomechanics Based on Tied‐Arch Principles
Integrative Zoology, EarlyView.This new biomechanical model explains the major stress and strain patterns generated through the cranium during biting. The model proposes that the cranium resolves bite‐induced reaction forces through arcs of compressive stress that span the cranial structure between biting teeth and both jaw joints.

Machine Learning‐Based Screening for Osteonecrosis of the Jaw in Panoramic Radiographs
Australian Dental Journal, EarlyView.ABSTRACT Background Osteonecrosis of the jaw (ONJ) is a serious condition associated mainly with antiresorptive therapy and maxillofacial radiotherapy. As detection of its radiographic findings may facilitate patient referral, this study aimed to develop convolutional neural networks (CNNs) for ONJ screening in panoramic radiographs (OPGs).
