What if we could observe genes firing off signals to cause some behaviors? We're getting closer. Researchers were able to directly match gene regulation with ritual mating behavior in fish. Their research field may also give some insight into autism spectrum disorder.
About 10 percent of men and 7 percent of women reported significant levels of distress and social impairment associated with difficulty controlling their sexual feelings, urges and behaviors.
An investigational oral antibiotic called zoliflodacin was well-tolerated and successfully cured most cases of uncomplicated gonorrhea when tested in a Phase 2 multicenter clinical trial, according to findings published today in the New England Journal of Medicine. The National Institute of Allergy and Infectious Diseases (NIAID), part of the US National Institutes of Health, sponsored the clinical study.
When Chlamydia trachomatis, the bacterium that causes one of the most common sexually transmitted infections worldwide, enters a human cell, it hijacks parts of the host to build protective layers around itself. Inside this makeshift fortress, the bug grows and reproduces, eventually bursting out in search of a new target and killing the host cell. While scientists have known for years that Chlamydia protects itself in this way, they were missing the mechanics until now.
The 21st century has ushered in a "quiet revolution" in the diversity of intimate relationships, and a leading scholar says the scale and pace of this social transformation warrants a "reboot" of relationship studies.
People are more prejudiced against women leaders than the statistics might indicate. This could be because participants in surveys investigating attitudes towards men and women in leadership positions may not answer honestly unless they are guaranteed confidentiality of their answers. These are the findings of a new study by Adrian Hoffmann and Jochen Musch of the Heinrich-Heine-University Düsseldorf in Germany, which is published in Springer's journal Sex Roles.
Societal acceptance of domestic violence against women is widespread in developing countries, with 36 per cent of people believing it is justified in certain situations.
Edible dormice are extremely long-lived thanks to their seasonal dormancy with hibernation periods lasting between at six and eleven months. Factors influencing the variable duration, apart from specific environmental conditions, have so far been unknown. Researchers at Vetmeduni Vienna hypothesised that older animals should shorten their winter dormancy in favour of a reproductive advantage and confirmed this for both sexes in a database analysis, published in Scientific Reports.
New Vanderbilt research finds how long humans and other warm-blooded animals live -- and when they reach sexual maturity -- may have more to do with their brain than their body. More specifically, it is not animals with larger bodies or slower metabolic rates that live longer; it is animals with more neurons in the cerebral cortex, whatever the size of the body.
Researchers in the Arizona State University Department of Psychology have found peer socialization and disruptive parenting were strong predictors of whether adults age 28-30 years were in a coercive romantic relationship. The 230 study participants were followed starting at age 11, and those who engaged in deviancy training at age 16-17 were more likely to end up in unhealthy relationships as adults.
