Bisexual men have a higher risk for heart disease compared with heterosexual men across several modifiable risk factors, finds a new study published online in the journal LGBT Health.
The evolutionary history and origin of syphilis, and other treponemal diseases, is a hotly debated topic by scholars. Scholars who theorize syphilis originated in the 'New World' and preceded the 15th century have been in fierce debate with scholars who theorize a multiregional origin followed by the 15th century pandemic spread. Both sides are supported by organic evidence found in contemporary genetic and skeletal remains across the globe.
An international group of researchers, involving scientists from Universidad Carlos III de Madrid (UC3M) and the Complexity Science Hub Vienna, developed a tool to track and analyze gender inequality through Facebook usage data. Their results, published in an article in the latest issue of Proceedings of the National Academy of Sciences (PNAS), show that gender inequality online is related to gender inequality in society at large.
A study of the victimization of women who were living in areas of high poverty and HIV prevalence in multiple cities across the US has shown that high-risk-sex, characterized by one or more HIV risk factors, was associated with a significantly greater likelihood of physical violence against the female participant within the subsequent six months.
Researchers found that a form of the estrogen hormone can contribute to drug relapse in females by worsening withdrawal symptoms. The study looked at the interaction of the female sex hormone estradiol and methamphetamine.
Girls in the first birth cohort to be offered and receive the HPV vaccine showed a lower degree of dysplasia which may eventually lead to cervical cancer than a birth cohort from 1983. This is the conclusion of a new study conducted by researchers at the University of Copenhagen, who have been the first to study the vaccine's effect on the general population.
Scientists have identified a key enhancer of Sox9 -- a gene critical for male sex development -- and demonstrated that deleting this non-coding DNA results in male-to-female sex reversal.
Male mice grow ovaries instead of testes if they are missing a small region of DNA that doesn't contain any genes -- a finding that could help explain disorders of sex development in humans, at least half of which have an unknown genetic cause.
Female genital mutilation (FGM) increases the risk of developing mental illness and changes the body's reactions to stress.
