A Guidance for Diagnosis, Control Measures, and Surveillance of Leptospirosis in Non‐Human Primates From a Veterinary Perspective in a One‐Health Approach

Journal of Medical Primatology, Volume 54, Issue 6, December 2025.
ABSTRACT Leptospirosis is an emerging zoonotic disease caused by pathogenic Leptospira spp., affecting a wide range of domestic and wild mammals including nonhuman primates (NHPs). Despite rising incidence rates in both NHPs and humans, there is a lack of comprehensive resources addressing leptospirosis in NHPs from a veterinary perspective in a One ...

Derivation of a health‐based guidance value for Δ8‐tetrahydrocannabinol (Δ8‐THC) and its occurrence in food

EFSA Journal, Volume 23, Issue 11, November 2025.
Abstract The European Food Safety Authority (EFSA) was asked to deliver a scientific opinion on the derivation of a health‐based guidance value (HBGV) for Δ8‐tetrahydrocannabinol (Δ8‐THC) in food with an assessment of the occurrence of Δ8‐THC and the co‐occurrence with Δ9‐THC in hemp and hemp‐derived products.

Relationships Between Intra‐Spinal Resting‐State Functional Connectivity and Electrophysiology Following Spinal Cord Injury

Human Brain Mapping, Volume 46, Issue 14, 01 October 2025.
Unilateral spinal cord injury in monkeys induces widespread and dynamic changes in resting‐state functional connectivity (rsFC), mirroring alterations in local field potential (LFP) coherence. Our findings reveal spatially and temporally complex intraspinal plasticity, supporting rsFC as a potential electrophysiologically grounded biomarker for ...

Same data, different results? Machine learning approaches in bioacoustics

Methods in Ecology and Evolution, Volume 16, Issue 8, Page 1574-1586, August 2025.
Abstract Automated acoustic analysis is increasingly used in behavioural ecology, and determining caller identity is a key element for many investigations. However, variability in feature extraction and classification methods limits the comparability of results across species and studies, constraining conclusions we can draw about the ecology and ...
