PURPOSE: Little is known about black African (BA) and black African-Caribbean (BAC) men's views towards cancer; yet culture and acculturation can contribute to the way in which people understand, explain and develop their attitudes towards cancer. Hence, cancer prevention and early detection strategies may not be sensitive to United Kingdom (UK)-based black men's views, affecting their awareness of risk factors and early detection services. This study explored the views of UK-based BA and BAC men towards cancer...

REVIEW
Cynthia D Cooper
Black pigment cells, melanocytes, arise early during development from multipotent neural crest cells. Melanocytes protect human skin from DNA damaging sunrays and provide color for hair, eyes and skin. Several disorders and diseases originate from these cells, including the deadliest skin cell cancer, melanoma. Thus, melanocytes are critical for a healthy life and for protecting humans from disease. Due to the ease of visualizing pigment cells through transparent larvae skin and conserved roles for zebrafish melanophore genes to mammalian melanocyte genes, zebrafish larvae offer a biologically relevant model for understanding pigment cell development and disease in humans...

While behavioural difficulties in facial emotion recognition (FER) have been observed in individuals with Autism Spectrum Disorder (ASD), behavioural studies alone are not suited to elucidate the specific nature of FER challenges in ASD. Eye tracking (ET) and electroencephalography (EEG) provide insights in to the attentional and neurological correlates of performance, and may therefore provide insight in to the mechanisms underpinning FER in ASD. Given that these processes develop over the course of the developmental trajectory, there is a need to synthesise findings in regard to the developmental stages to determine how the maturation of these systems may impact FER in ASD...

The tight link of saccades to covert spatial attention has been firmly established, yet their relation to other forms of visual selection remains poorly understood. Here we studied the temporal dynamics of feature-based attention (FBA) during fixation and across saccades. Participants reported the orientation (on a continuous scale) of one of two sets of spatially interspersed Gabors (black or white). We tested performance at different intervals between the onset of a colored cue (black or white, indicating which stimulus was the most probable target; red: neutral condition) and the stimulus...

Elongation of very long-chain fatty acid (Elovl) 4 proteins are important fatty acyl elongases that participate in the biosynthesis of long-chain (C20-24) and very long-chain (˃C24) polyunsaturated fatty acids (LC-PUFA and VLC-PUFA, respectively) in teleost fish, especially in marine species. Moreover, knowledge of Elovl4 and other elongases such as Elovl2 has contributed to an advanced understanding of the LC-PUFA biosynthetic pathway in marine fish. In the present study, elovl4a and elovl4b were cloned from black seabream Acanthopagrus schlegelii and functionally characterised using recombinant expression in yeast...

To date, there is a noticeable lack of studies that focus exclusively on the pedagogical practices, teaching experiences, identity, and gender performances of Black and Brown lesbian educators (BBLE). This special issue of the Journal of Lesbian Studies aims to make the hyperinvisibility of BBLE visible and proposes to fill this scholarly gap by exploring this topic from a variety of cultural and disciplinary perspectives.

Carotenoid-based traits or ornaments, such as yellow-red integuments (feathers, beaks, legs or eye-rings) displayed by birds, play key roles in social communication by reliably advertising an individual's quality or health. In some species, these traits are displayed not only by adults but also by nestlings, and function in parent-offspring communication or sibling competition by advertising an individual's physical or physiological condition. Pollutants such as organochlorine compounds (OCs) could have disruptive effects on the coloration of these traits, thereby interfering with communication processes...

In six studies ( N = 605), participants made deception judgments about videos of Black and White targets who told truths and lies about interpersonal relationships. In Studies 1a, 1b, 1c, and 2, White participants judged that Black targets were telling the truth more often than they judged that White targets were telling the truth. This truth bias was predicted by Whites' motivation to respond without prejudice. For Black participants, however, motives to respond without prejudice did not moderate responses (Study 2)...
