Inspired by artist Tauber-Arb and the discoveries of @mariafelicita.bsky.social, @oliviawalch.bsky.social made this to show how brain cancers grow in response to morning hormonal signals. What do you see?
The association between more cumulative circadian disruption and worse sleep and body weight may not be surprising, but it could set the stage to test interventions that reduce chronodisruption to improve health.
