The floral traits of bisexual flowers may evolve in response to selection on both male and female functions, but the relative importance of selection associated with each of these two aspects is poorly resolved. Sexually dimorphic traits in plants with unisexual flowers may reflect gender-specific selection, providing opportunities for gaining an increased understanding of the evolution of spec...

Surgical correction of cicatricial alopecia can yield exceptional results when performed in the appropriate clinical scenario. To facilitate determination of the most suitable corrective therapy, we propose two new categories of cicatricial alopecia: "unstable" and "stable." Unstable cicatricial alopecia is intermittent and results in possible subsequent scarring hair loss in either new or old ...

Hair has historically reflected material consequences in the Black community; thus, research has begun to investigate how the power/privilege matrix that is propagated throughout the media permeates society and impacts African-American women’s perceptions of hair. This research joins the discussion by exploring how Black hair magazine advertisements influence Black women’s hair styles and their...

Background Hair is an ectodermal structure, and its formation is regulated by master genes important in embryology. Hair shaft consists of three major regions: the medulla, cortex and cuticle. Hair shaft abnormality will divide structural hair abnormalities into two broad categories - those associated with increased hair fragility and those not associated with increased hair fragility. We condu...

Across four studies, people sat (or reported they would sit) closer to physically similar others. Study 1 revealed significant aggregation in seating patterns on two easily observed characteristics: glasses wearing and sex. Study 2 replicated this finding with a wider variety of physical traits: race, sex, glasses wearing, hair length, and hair color. The overall tendency for people to sit besi...

a r t i c l e i n f o Facial hair strongly influences people's judgments of men's socio-sexual attributes. However, the nature of these judgments is often contradictory. The levels of intermediate facial hair growth presented to raters and the stage of female raters' menstrual cycles might have influenced past findings. We quantified men's and women's judgments of attractiveness, health, mascul...

People frequently evaluate facial attractiveness and make We tested four acquired prosopagnosics. Florence is a 29inferences about character traits from faces, and these evaluations are consistent across observers (Todorov, Said, & Verosky, 2011). Do these face evaluations rely on the same perceptual mechanisms as facial identity recognition? Recent studies claim they do not. Some individuals w...
