Scientists at The Graduate Center of The City University of New York and Brooklyn College have discovered seasonal changes in dopamine levels in the female plainfin midshipman fish's inner ear helps hearing sensitivity grow in the summer mating season, making her better able to hear the male's mating calls.
A randomised trial of more than 7,800 African women found that a type of contraceptive injection (intramuscular depot medroxyprogesterone acetate -- DMPA-IM) posed no substantially increased risk of HIV acquisition when compared with a copper intrauterine device (IUD) and a levonorgestrel (LNG) implant. The results of this first ever randomised trial in the area, published in The Lancet, counter 30 years of epidemiology research suggesting a potential association between some types of contraceptives and risk of acquiring HIV.
In a recent University of Washington study, researchers interviewed women 'Wikipedians' to examine the lack of female and non-binary editors in Wikipedia.

In a new recommendation, the US Preventive Services Task Force (USPSTF) recommends clinicians offer preexposure prophylaxis (PrEP) with effective antiretroviral therapy to people at high risk of acquiring HIV to decrease their risk of infection with the virus that causes AIDS.
Sexually active Australian secondary students tend to engage in responsible sexual behaviour but there is still room to improve knowledge and education for this group, according to a nationwide survey conducted by La Trobe University.
A new study by CUNY SPH researchers found that the adoption of the WHO's 2015 'Treat All' recommendation was followed by large increases in rapid initiation of antiretroviral therapy (ART) in six sub-Saharan African countries.
A new study from Professor Doug VanderLaan's lab in UofT Mississauga's Department of Psychology looking at biological mechanisms that are often thought to influence male sexual orientation was published in the latest edition of PNAS.
Inequality between men and women was not generally consolidated in Iberia during the Neolithic. However, situations progressively appeared that indicate dominance of men over women. Four important lines in which inequality between men and women can be investigated through successive historical periods are their access to funeral rites, the material conditions of their existence, the appearance of specific social roles for each of the genders and the growing association of men with violence.
