Recent progress in studies of the last million years of human physical and behavioural evolution Avancées récentes dans l’étude du dernier million d'années d’évolution physique et éthologique de l'espèce humaine

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.

The Swanscombe fossil at 90: revisiting its phylogeny, taxonomy, and place in human origins Le fossile de Swanscombe, 90 ans après : retour sur sa place phylogénique, taxonomique et dans les origines de l'humanité

open access: yesJournal 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 ...

Indirect fractures in long bones resulting from gunshot trauma: Occurrence, characterization, and need for additional research

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Indirect fractures from gunshot wounds can occur when a projectile impacts soft tissue without making direct contact with the bone. Existing biomechanical and clinical research suggests that indirect fractures result in lower levels of comminution, and that resultant fracture patterns can resemble those seen in blunt force trauma (e.g., wedge ...

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

open access: yesInsect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

A New Model of Feeding Biomechanics Based on Tied‐Arch Principles

open access: yesIntegrative 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.
