Animals are communicating — but what are they saying? And can we talk back? Marine biologist David Gruber introduces Project CETI: a team of scientists, linguists and AI specialists hoping to decode sperm whale language. Using noninvasive robots and a machine-learning algorithm to collect and analyze millions of sperm whale vocalizations known as coda, the team aims to demystify the communication structures and dialects of these majestic creatures — and possibly even crack the interspecies communication code. (This ambitious plan is a part of the Audacious Project, TED’s initiative to inspire and fund global change.)

When she was diagnosed with narcolepsy, she finally got the wake-up call that transformed her life. In this rousing talk, she discusses the epidemic of undiagnosed sleep disorders and encourages you to ask yourself: Is your tiredness different? (Recorded at TEDxSonomaCounty on March 7, 2026)
