Scientists demonstrated that, contrary to what had been assumed for several years, colour variations among female macaques do not precisely indicate the time of ovulation. On the other hand, dominant female macaques, who usually have greater reproductive success, have darker hindquarters.
The good news is that adolescent sexting is not at epidemic levels as reported in some media headlines. The bad news is that it also has not decreased despite preventive efforts by educators and others, according to a much-needed update to what is currently known about the nature and extent of sexting among youth today.
A survey analysis suggests that, between 2016 and 2018, the relationship between workplace sexual harassment and women's negative self-views weakened. Ksenia Keplinger and colleagues at the Leeds School of Business at the University of Colorado Boulder, US, present these findings in the open access journal PLOS ONE on July 17, 2019.
A new study published in the Journal of the International AIDS Society shows that the World Health Organization's (WHO) 2015 recommendation for immediate treatment of all people living with HIV has become the standard of care across HIV clinics in countries around the world. While most countries have adopted the WHO's "Treat All" recommendation, the extent to which these guidelines had been translated into practice at HIV clinics around the world was previously unknown.
The number of syphilis cases has been consistently going up across Europe since 2010, mostly affecting men who have sex with men living in urban areas. In 2017, notification rates reached an all-time high in the EU/EEA countries with more than 33,000 reported cases. An in-depth ECDC study describes the factors behind this increase and outlines the evidence-based options for public health control of syphilis, including case finding and management as well as educational activities.
Adults who were born preterm (under 37 weeks gestation) are less likely to have a romantic relationship, a sexual partner and experience parenthood than those born full term. The meta-analysis by researchers at the University of Warwick with data from up to 4.4 million adult participants showed that those born preterm are 28% less likely to ever be in a romantic relationship.
The number of women regularly having sex declines with age, and the number of women enjoying sex postmenopause is even lower. Although these facts are not surprising, the causes for these declines may be because previous research focused largely on biological causes only. However, a new UK study identifies psychosocial contributors. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
Top male biathletes are more attractive to the opposite sex, according to a new study by scientists at the universities of Exeter and Bristol.
Two new studies developed algorithms that can identify patients who are at risk of acquiring HIV and may benefit from preventive care. Both studies appear in the July 5, 2019 issue of The Lancet HIV.
Very little is known about how the onset of puberty is controlled in humans, but the discovery of a new gene in the roundworm C. elegans could be the 'missing link' that determines when it's time to make this juvenile-to-adult transition.
