OBJECTIVE: A resurgence in bacterial STIs, notably syphilis, among gay, bisexual and other men who have sex with men (MSM) has been detected in England. A Canadian modelling study postulated that antiretroviral therapy (ART) may...
Suppressing subordinate reproduction provides benefits to dominants in cooperative societies of meerkats.
In many animal societies, a small proportion of dominant females monopolize reproduction by actively suppressing subordinates. Theory assumes that this is because subordinate reproduction depresses the fitness of dominants, yet...

INTRODUCTION: Alcohol use by persons living with HIV/AIDS (PLWHA) negatively impacts the public health benefits of antiretroviral therapy (ART). Using a standardized alcohol assessment tool, we estimate the prevalence of alcohol...
Can HIV-positive gay men become parents? How men living with HIV and HIV clinicians talk about the possibility of having children.
Linguistically complex recognition prompts in pre-recorded cross-examinations.
This study examined the effects of pre-trial preparation and pre-recorded cross-examinations on the linguistic complexity of recognition prompts (i.e., option-posing or suggestive questions) used when questioning child victims...
Morphological and genomic shifts in mole-rat 'queens' increase fecundity but reduce skeletal integrity.

In some mammals and many social insects, highly cooperative societies are characterized by reproductive division of labor, in which breeders and nonbreeders become behaviorally and morphologically distinct. While differences in...

Gender dysphoria (GD) is characterized by distress due to an incongruence between experienced gender and sex assigned at birth. Brain functional connectivity in adolescents who experience GD may be associated with experienced...

Compulsive sexual behavior
Casper Schmidt, Laurel S Morris, Timo L Kvamme, Paula Hall, Thaddeus Birchard, Valerie Voon
Dec 13, 2016
BACKGROUND: Compulsive sexual behaviors (CSB) are relatively common and associated with significant personal and social dysfunction. The underlying neurobiology is still poorly understood. The present study examines brain...

Female university students' preferences for different types of sexual relationships
BACKGROUND: Gender-based violence among young women is a growing problem worldwide. The consequences of this victimization have been well reported in the scientific literature, among which negative health outcomes stand out. The...

Colour pattern is the main trait that drives mate recognition between Heliconius species that are phylogenetically close. However, when this cue is compromised such as in cases of mimetic, sympatric and closely related species...
Divergent receiver responses to components of multimodal signals in two foot-flagging frog species.
Multimodal communication of acoustic and visual signals serves a vital role in the mating system of anuran amphibians. To understand signal evolution and function in multimodal signal design it is critical to test receiver...
Fine-scale genetic structure reflects sex-specific dispersal strategies in a population of sociable weavers (Philetairus socius).
The reach of gene-culture coevolution in animals.
Culture (behaviour based on socially transmitted information) is present in diverse animal species, yet how it interacts with genetic evolution remains largely unexplored. Here, we review the evidence for gene-culture...
