University of California: Sleep scientists Louis Ptáček, MD, and Ying-Hui Fu, PhD, have discovered several genes that lead to short, hyper-efficient sleep.

Sleep researchers and clinicians from across the UCSF Weill Institute for Neurosciences are pushing for answers. “Our team is drilling down on this question of how much sleep people need in ways that are pushing the envelope forward and are ahead of most other places,” says Andrew Krystal, M.D., vice chair of research in the Department of Psychiatry and Behavioral Sciences, the Dolby Professor of Psychiatry, and a leader of a cross-departmental initiative on the neuroscience of sleep.
