Men are more prone to competitive risk taking and violent behavior, so what happens when the number of men is greater than the number of women in a population? According to research by Florida State University Professor of Psychology Jon Maner, the answers might not be what you expect.
Prolonged fear and anxiety brought on by major stressors, like the coronavirus pandemic, can not only take a toll on a person's mental health, but may also have a lasting impact on a man's sperm composition that could affect his future offspring. That is the finding of a provocative new study published in the journal Nature Communications by researchers at the University of Maryland School of Medicine.
A study published in PLOS ONE showed that an internet-based version of Harvard's Mind/Body Program for Fertility achieved results similar to the in-person program, more than doubling pregnancy rates for women experiencing infertility, compared with a control group. The findings are significant because women in infertility treatment tend not to access in-person counseling and often give up on their dream of having a child.
Tokyo, Japan - Scientists from Tokyo Metropolitan University have discovered that Drosophila flies lose long-term memory (LTM) of a traumatic event when kept in the dark, the first confirmation of environmental light playing a role in LTM maintenance. The team also identified the specific molecular mechanism responsible for this effect. LTMs are notoriously difficult to erase; this work may lead to novel treatments for sufferers of trauma, perhaps even the erasure of life-altering traumatic memories.
Baboon mothers living in the wild carry dead infants for up to 10 days, according to a new study led by UCL and Université de Montpellier.
A new study found that two-thirds of female adolescents ages 16-21 seen in a pediatric Emergency Department (ED) were interested in discussing contraception, despite having a high rate of recent visits to a primary care provider. More than 22% indicated that they would be likely to start or change contraception during the ED visit.
The risk of physical and sexual violence faced by gay, lesbian, bisexual and questioning US high schoolers was quantified in this observational study that used pooled data from a survey conducted every two years by the Centers for Disease Control and Prevention.
Earlier research purported to show links between a woman's cycle and how attracted she was to men's behavior. Research at the University of Göttingen questions this. It showed shifts in women's cycles did not affect their preferences for men's behavior. Researchers found, however, that when fertile, women found all men slightly more attractive. Irrespective of their cycle, flirtier men were evaluated as more attractive for sexual relationships but less for long-term relationships. Results appeared in Psychological Science.
Researchers from Michigan State University are the first to pinpoint social factors that can reduce these stressors and improve health for LGBT people.
University of Kent research suggests that men can distinguish between the scents of sexually aroused and non-aroused women. The detection of sexual arousal through smell may function as an additional channel in the communication of sexual interest and provide further verification of human sexual interest.
