What's wrong with US healthcare and how startups can fix it, with Justin Mares

Matias and Greg interview Ying-Hui Fu, PhD, is a Professor of Neurology at UCSF and a world leader in the genetics of sleep. Her lab has discovered the first-known genes behind “natural short sleepers”. Her work bridges human genetics and neuroscience to uncover how to modulate sleep for brain health, aging, and neurodegenerative diseases.In this episode, we discuss:How some people thrive on 4–6 hours of sleep with rare genetic mutationsWhy sleep efficiency is more important than total hours sleptWhat short sleeper genes reveal about preventing Alzheimer’s and autismWhy current sleep research tools miss deeper brain activity patternsWhat’s next in sleep science with potential therapiesCredits:Created by Greg Kubin and Matias SerebrinskyHost: Matias Serebrinsky & Greg KubinProduced by Caitlin Ner & Nico V.
