In an honor reserved for only the most significant achievements in advancing children’s health, Children’s Hospital of Philadelphia (CHOP) has awarded its Gold Medal to Katherine High, MD, a gene therapy pioneer and one of the lead developers of the first in vivo gene therapy approved by the Food and Drug Administration (FDA). Bestowed only 12 times in CHOP’s 167-year history, the Gold Medal highlights Dr. High’s groundbreaking discoveries at CHOP, which led to a gene therapy treatment for a rare form of inherited blindness and advanced gene therapy for hemophilia to late-stage testing.

Scientists from the Broad Institute of MIT and Harvard have developed a first-of-its-kind cross-tissue cell atlas, and in collaboration with researchers at Mass Eye and Ear, have uncovered new clues for specific cell types and genes involved in complex diseases. In a new study published May 12 in Science, researchers described for the first time how their novel cross-tissue cell atlas derived from an analysis of nuclei from 25 frozen samples from 8 tissue types may increase understanding of the cellular and genetic underpinnings of complex diseases, including heart disease and cancers.

Researchers have identified distinct differences among the cells comprising a tissue in the retina that is vital to human visual perception. The scientists from the National Eye Institute (NEI) discovered five subpopulations of retinal pigment epithelium (RPE)—a layer of tissue that nourishes and supports the retina’s light-sensing photoreceptors. Using artificial intelligence, the researchers analyzed images of RPE at single-cell resolution to create a reference map that locates each subpopulation within the eye.

UC San Diego researchers developed a smartphone app that could allow people to screen for Alzheimer's disease, ADHD and other neurological diseases and disorders—by recording closeups of their eye. The app uses a smartphone's built-in near-infrared camera and selfie camera to track how a person's pupil changes in size. These pupil measurements could be used to assess a person's cognitive condition.
