Cancer watch: an actigraphy device @mariafelicita.bsky.social @erikherzog.bsky.social @oliviawalch.bsky.social & team establish a real-time, non-invasive monitoring tool for glioblastoma progression based on activity, enabling early progression detection: doi.org/10.1172/jci....

Dosing on the way down improves outcomes for glioblastoma. Thanks Maddy Frank for covering this collaboration with @oliviawalch.bsky.social and WashU grad student @mariafelicita.bsky.social. #chronotherapy #circadian #medicine source.washu.edu/2025/11/timi...

Permanent Standard Time would let us sleep naturally past dawn. Daylight Saving Time makes us wake by alarm in darkness. Tell lawmakers to ditch DST! 🔗👇

Very excited for this to come out! Awesome work by @mariafelicita.bsky.social

Digital twin is a term that means ten different things to ten different people. For our app, Arcashift, "sleep + circadian digital twin" means: - we have a system of differential equations that acts like your brain acts in response to light and other stimuli - and also a cute character builder

Arcascope, Inc.@arcascope.bsky.social · 2y ago

Our CEO, Olivia Walch, describes Arcascope’s digital twin as a crash test dummy for your sleep: simulating thousands of outcomes to give you the best sleep, energy, and circadian rhythm strategies. Read more on our website: arcascope.com/what-a-sleep... #CircadianRhythms #DigitalTwin

Cancer-related fatigue is tough—but it doesn’t have to be. A new study with @UMRogelCancer shows our personalized circadian rhythm app, Arcasync, can reduce daily fatigue in cancer patients. Published in Cell Reports Medicine: www.newswise.com/articles/per... #CircadianHealth #CancerCare

Personalized App Reduces Cancer-Related Fatigue | Newswise

U-M researchers, in collaboration with Arcascope, have developed and tested a personalized app that tracks a user’s circadian rhythm and makes behavioral recommendations to reduce daily fatigue.
