‘Lefty’ tightens control of embryonic development

A protein known as Lefty pumps the brakes as human embryos begin to differentiate into the bones, soft tissues and organs that make us. This inhibitor protein is key during the early stages of life when the fates of embryonic stem cells are determined by the Nodal signaling pathway, according to Rice University bioscientists. […]

NIH study classifies vision loss and retinal changes in Stargardt disease

National Eye Institute researchers developed and validated an artificial-intelligence-based method to evaluate patients with Stargardt, an eye disease that can lead to childhood vision loss. The method quantifies the disease-related loss of light-sensing retina cells, yielding information for monitoring patients, understanding genetic causes of the disease, and developing therapies to […]
