Repetitive elements shape embryonic chromatin landscape

Scientists from Helmholtz Zentrum München have found that retrotransposons, particularly LINE1 elements, regulate global chromatin accessibility in the early mouse embryo. This study identifies a novel role for retrotransposons in shaping the chromatin landscape necessary for correct developmental programming.

Self-identifying as disabled and developing pride in disability aid overall well-being

A study from Oregon State University found that people who experience stigma are more likely to self-identify as disabled and develop pride in their disability. The researchers also discovered that severe impairments lead to greater stigma, which can increase the likelihood of self-identification. Developing disability pride is associa...
