NIH researchers have identified a series of changes in the architecture and cell composition of connective tissues of the breast, known as stromal tissue, associated with an increased risk of developing aggressive breast cancer among women with benign breast disease, and poorer rates of survival among women with invasive breast cancer.

NIH scientists have leveraged artificial intelligence (AI) to transform a device designed to see tissues in the back of the eye into one sharp enough to see individual cells. The technique provides imaging resolution that rivals the most advanced devices available. It’s cheaper, faster and doesn’t require specialized equipment or expertise.

New studies in rats suggest the drug reserpine, approved in 1955 for high blood pressure, might treat the blinding disease retinitis pigmentosa. No therapy exists for this rare inherited disease, which starts affecting vision from childhood. A report on the studies, conducted at NIH, was published in eLife.
