    • The use and misuse of race in health care

    In a Q&A, PIK Professor Sarah Tishkoff, the Perelman School of Medicine’s Giorgio Sirugo, and Case Western Reserve University’s Scott Williams shed light on the “quagmire” of race, ethnicity, genetic ancestry, and environmental factors and their contribution to health disparities.

    How humans evolved a super-high cooling capacity

    The higher density of sweat glands in humans is due, to a great extent, to accumulated changes in a regulatory region of DNA that drives the expression of a sweat gland-building gene, explaining why humans are the sweatiest of the Great Apes.

    A mutation in the NPHP5 gene leads to a severe blinding disorder, Leber congenital amaurosis. Dogs with the condition that were treated with a gene therapy regrew normal, functional cone cells, labeled in red, that had previously failed to develop. The treatment led to a recovery of retinal function and vision. (Image: Courtesy of Gustavo Aguirre and William Beltran)

    Turning back the clock on a severe vision disorder
