Ignoring the planet: A critical blind spot for research on ageing

Journal of Internal Medicine, Volume 298, Issue 6, Page 578-590, December 2025.
Abstract Although research on ageing has largely concentrated on understanding the fundamental biology of the ageing process and devising pharmaceutical interventions in order to slow it down, increasing evidence has underscored the crucial role of environmental inputs across the life course and across generations, in shaping both individual and ...

Phocid seal leptin: tertiary structure and hydrophobic receptor binding site preservation during distinct leptin gene evolution. [PDF]

PLoS ONE, 2012
The cytokine hormone leptin is a key signalling molecule in many pathways that control physiological functions. Although leptin demonstrates structural conservation in mammals, there is evidence of positive selection in primates, lagomorphs and ...

Avian influenza overview September–November 2025

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract Between 6 September and 28 November 2025, 2896 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (442) and wild (2454) birds in 29 countries in Europe. The magnitude and geographical extent of these detections were unprecedented for this time of the year, particularly in wild birds.

Biogeography and History of the Prehuman Native Mammal Fauna of the New Zealand Region

Diversity
The widespread perception of New Zealand is of a group of remote islands dominated by reptiles and birds, with no native mammals except a few bats. In fact, the islands themselves are only part of a wider New Zealand Region which includes a large section

Effect of angle on flow-induced vibrations of pinniped vibrissae. [PDF]

PLoS ONE, 2013
Two types of vibrissal surface structures, undulated and smooth, exist among pinnipeds. Most Phocidae have vibrissae with undulated surfaces, while Otariidae, Odobenidae, and a few phocid species possess vibrissae with smooth surfaces.

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

Advanced 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
