Male Broad-tailed Hummingbirds perform dramatic aerial courtship dives to impress females. In a new study, scientists have shown that diving males closely time key events to produce a burst of signals for the viewer. They synchronize maximal horizontal speed, loud noises generated with their tail feathers, and a display of their iridescent throat-patch (gorget), performed in a mere 300 milliseconds -- roughly the duration of a human blink.

An increasing number of scientists are including female animals in their experimental designs and analyses for preclinical studies, as required by the National Institutes of Health (NIH) in January 2016, reports a new study. But NIH reviewers are not necessarily considering that inclusion when they score an application for funding, which was a goal of the requirement.
A new study has shown that HIV-infected men had lower median bone mineral density (BMD) scores at the hip compared to HIV-uninfected men, and all men who received testosterone had significantly greater BMD scores at the lumbar spine.
A new study published in the journal Sexual Medicine indicates that sexual activity is associated with improved wellbeing amongst older adults, measured through higher enjoyment of life scores.
Sex workers who face repressive policing are more likely to experience violence and poorer health and well-being, according to new research published in PLOS Medicine.
Gay, lesbian, bisexual and questioning youth are more likely to experience depressive symptoms from as young as age 10 and these symptoms persist at least into their early 20s, finds a new UCL-led study.
Depressive symptoms more common among sexual minority youth than heterosexual youth at age 10, develop faster during adolescence, and continue into young adulthood, but start to decline from age 18.
Younger breast cancer patients who underwent mastectomy reported lower breast satisfaction and poorer psychosocial and sexual well-being compared with those who underwent breast-conserving surgery, according to results of a trial presented at the 2018 San Antonio Breast Cancer Symposium.
