Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Deletion of Astrocytic TNFR1 Attenuates Hyperexcitability and Initiation of Epileptogenesis

Glia, Volume 74, Issue 9, September 2026.
Inducible, astrocyte‐specific deletion of TNFR1 reduces basal EEG spectral power. Loss of astrocytic TNFR1 attenuates acute seizure activity in two distinct experimental models of epilepsy. Deletion of TNFR1 in astrocytes limits epilepsy development and hippocampal pathology in a mouse model of temporal lobe epilepsy with hippocampal sclerosis ...

Dorsal raphe tau pathology disrupts sleep‐wake orchestration and sleep architecture in a sex‐specific manner

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Sleep disturbances are frequent symptoms of Alzheimer's disease (AD), mirrored by early pathology in the dorsal raphe nucleus (DRN). Whether early DRN pathology can drive sleep disturbances, and the relative contributions of serotonin (5‐HT) and sex, has not been directly tested.

Cannabidiol reduces atypical absence seizures and epileptic spasms in a Gabrb3+/D120N mouse model of Lennox–Gastaut syndrome

Epilepsia Open, Volume 11, Issue 4, Page 1263-1275, August 2026.
Abstract Objective Lennox–Gastaut syndrome (LGS) is a drug‐resistant developmental and epileptic encephalopathy (DEE). Preclinical drug development for LGS is constrained by a lack of syndrome‐relevant animal models. We aimed to evaluate a Gabrb3+/D120N knock‐in (KI) mouse model of LGS by quantifying atypical absence seizures and epileptic spasms and ...

Diet composition of the African manatee: Spatial and temporal variation within the Sanaga River Watershed, Cameroon

Ecology and Evolution, 2021
The present study aimed to investigate the diet of African manatees in Cameroon to better inform conservation decisions within protected areas. A large knowledge gap on diet and seasonal changes in forage availability limits the ability to develop ...

Cytochemical staining of leukocytes and platelets in the Florida manatee (Trichechus manatus latirostris): identification of a bilobed monocyte similar to other members of the Paenungulata

Frontiers in Veterinary Science, 2023
Manatees (Antillean-, Amazonian, and African-) and dugongs belong to the Order Sirenia, and when combined with elephants and rock hyraxes, form the Paenungulata. A bilobed mononuclear cell has previously been identified in elephants and rock hyraxes, but

Effectiveness of current and potential conservation actions for amphibians, birds and mammals

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
Our study demonstrates the power of combining differently‐sourced and compiled datasets to evaluate the likely effectiveness of ongoing conservation strategies and identify future needs. Our findings can inform species action plans and conservation spatial‐planning tools, helping to ensure that future conservation efforts are evidence‐based, have ...
