Role of the Setae in an Ectoparasitic Seal Louse in Reducing Surface Drag: Numerical Modeling Approach

open access: yesAdvanced Theory and Simulations, Volume 8, Issue 10, October 2025.
The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design

Neandertal Cold Adaptation: Technological, Anatomical, and Physiological Responses to Cold Stress in One of Our Closest Fossil Relatives

open access: yesAmerican Journal of Human Biology, Volume 37, Issue 10, October 2025.
ABSTRACT Neandertals occupied western Eurasia for over 100 000 years, repeatedly enduring climates that ranged from seasonally cold to glacial. This paper reexamines the question of Neandertal cold adaptation using updated fossil, physiological, and archaeological evidence.

Pediculosis palpebrarum initially diagnosed as blepharitis

open access: yesAfrican Vision and Eye Health, 2009
Pediculosis is an infestation of lice. Eyelid involvement is uncommon, but can be caused by pediculus humanus capitis (head louse), rarely by  pediculus humanus corporis (body louse) and commonly by phthirus pubis (pubic louse).

PINK1 deficiency permits the development of Lewy body dementia with coexisting Aβ pathology

open access: yesAlzheimer's &Dementia, Volume 21, Issue 9, September 2025.
Abstract INTRODUCTION Dementia with Lewy bodies (DLB), a prevalent neurodegenerative dementia, involves α‐synuclein (α‐syn) aggregates and frequent amyloid beta (Aβ) co‐pathology, but mechanistic drivers remain unclear. METHODS We crossed pink1 knockout with APP/PS1 mice, and assessed behavioral and pathological phenotypes of the resulting animals.
