Should We Make Daylight Saving Time Permanent?

Join us! Ask Me Anything as part of the #SRBR World Circadian Day. Organized with expert researchers and physicians studying #biologicalrhythms and #sleep. Real-time responses starting in just 5 circadian cycles from now.

Circadian interventions (light, small molecules targeting the clock, food) can improve glymphatics, improve stroke recovery, and reduce neuroinflammation! This was a 5 yr effort from Hablitz Lab (with the assist from Nedergaard lab) out now in JCI! Hope you enjoy! www.jci.org/articles/vie...

Timing matters: @erikherzog.bsky.social @washu.edu , Joshua Rubin and team analyzed 5 years of glioblastoma biopsy results and conclude, “We are hopeful that this chronodiagnostic approach will help identify better ways to treat this devastating disease.” Published in the Journal of Neuro-Oncology.

Timing may be key to effective cancer treatments

Researchers at Washington University in St. Louis find the timing of biopsy can affect how doctors diagnose tumors and when those cancers may be more sensitive to chemotherapy.

And here is the story after peer review. This work highlights our current approach, which is to use Piezo channels to uncover new areas of biology that are shaped by mechanical forces: www.science.org/doi/10.1126/...

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.
