Ackman funds $400M institute after daughter's experimental eye treatment fails
Billionaire Bill Ackman's 26-year-old daughter, Lucy, received an experimental mitochondrial transplant to restore vision lost after a brain hemorrhage. The procedure, the first of its kind in human eyes, initially restored light perception but the effect faded within a month. Ackman has since pledged over $400 million to a new research institute focused on brain science and aging.
