Risk posed by the HPAI virus H5N1, Eurasian lineage goose/Guangdong clade 2.3.4.4b. genotype B3.13, currently circulating in the US

EFSA Journal, Volume 23, Issue 7, July 2025.
Abstract The emergence of highly pathogenic avian influenza (HPAI) A(H5N1), clade 2.3.4.4b, genotype B3.13 in U.S. dairy cattle marks a significant shift in the virus' host range and epidemiological profile. Infected cattle typically exhibit mild clinical signs, such as reduced milk production, mastitis and fever, with morbidity generally below 20% and

Three‐Dimensional Limb Kinematics in Brown‐Throated Three‐Toed Sloths (Bradypus variegatus) During Suspensory Quadrupedal Locomotion

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 5, Page 564-577, June 2025.
ABSTRACT Suspensory locomotion differs significantly from upright quadrupedal locomotion in mammals. Nevertheless, we know little concerning joint kinematics of suspensory movement. Here, we report three‐dimensional kinematic data during locomotion in brown‐throated three‐toed sloths (Bradypus variegatus). Individuals were recorded with four calibrated

The Initial Opening of the Drake Passage Occurred During ca. 62‐59 Ma

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Although the Drake Passage has been considered a critical component of ocean circulation and climate, its initial opening age remains controversial due to the weak constraints on the paleoposition of the Antarctic Peninsula. Here, new zircon U‐Pb geochronological studies are conducted on the Barchans Islands, providing a critical age ...

Numerous independent gains of daily torpor and hibernation across endotherms, linked with adaptation to diverse environments

Functional Ecology, Volume 39, Issue 3, Page 824-839, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many endotherms from diverse taxonomic groups can respond to environmental changes through torpor, that is, by greatly reducing their energy expenditure for up to 24 hours (daily torpor) or longer (hibernation).
