Background: The prevailing sex education (SE) model falls within a neoliberal prevention- and risk-oriented paradigm. This model ignores the identity dimension of sexuality, is based on the cis-heteronormative and ethnocentric matrix and stigmatizes sexual and cultural diversity; this has significant consequences for sexually and culturally diverse adolescents and youth. In this study, we explored the potential of the identity dimension of SE to prevent violence toward sexual and cultural diversity. Specifically, our objective was to identify the influence of heteronormative and ethnocentric variables on violence exerted against trans* and gender-diverse people and people from minority ethnic groups. Methods: A total of 623 Spanish adolescents with a mean age of 14.73 years and an age range of 13 to 18 years participated in the study. Students completed a questionnaire that included measures regarding violence toward sexual and cultural diversity, gender stereotypes, sexist attitudes and rejection of sexual and cultural diversity. We performed two hierarchical linear regression models. Results: Students who exerted the highest amount of violence toward trans* and gender-diverse people were those who showed the lowest endorsement of expressive traits and the highest endorsement of instrumental traits as well as the highest level of hostile sexist, heteronormative and hostile racist attitudes (the five predictor variables explained 29.1% of the variance of gender-bashing). These same variables—except expressiveness—and benevolent sexism explained 46.1% of the variance of rejection of minority ethnic groups. Conclusions: There is a need for a comprehensive, intercultural, critical and queer SE aimed at transforming the classroom into a space that promotes social transformation through an educational practice that is transgressive and critical of cis-heteronormativity and normative ethnocentrism.

Genome-editing, a recent technological advancement in the field of life sciences, is one of the great examples of techniques used to explore the understanding of the biological phenomenon. Besides having different site-directed nucleases for genome editing over a decade ago, the CRISPR/Cas (clustered regularly interspaced short palindromic repeats/CRISPR-associated protein) based genome editing approach has become a choice of technique due to its simplicity, ease of access, cost, and flexibility. In the present review, several CRISPR/Cas based approaches have been discussed, considering recent advances and challenges to implicate those in the crop improvement programs. Successful examples where CRISPR/Cas approach has been used to improve the biotic and abiotic stress tolerance, and traits related to yield and plant architecture have been discussed. The review highlights the challenges to implement the genome editing in polyploid crop plants like wheat, canola, and sugarcane. Challenges for plants difficult to transform and germline-specific gene expression have been discussed. We have also discussed the notable progress with multi-target editing approaches based on polycistronic tRNA processing, Csy4 endoribonuclease, intron processing, and Drosha ribonuclease. Potential to edit multiple targets simultaneously makes it possible to take up more challenging tasks required to engineer desired crop plants. Similarly, advances like precision gene editing, promoter bashing, and methylome-editing will also be discussed. The present review also provides a catalog of available computational tools and servers facilitating designing of guide-RNA targets, construct designs, and data analysis. The information provided here will be useful for the efficient exploration of technological advances in genome editing field for the crop improvement programs. Full article
