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...

Me doing my best to regulate my body clock using that sweet sweet Florida sunshine! Thanks again @oliviawalch.bsky.social for the time and the chat for @smbmathbiology.bsky.social's podcast #BiologyInNumbers. It was super cool learning about your work @arcascope.bsky.social ⏰☀️💊 #scicomm

Really enjoyed chatting with @parmvir.com on the Biology in Numbers podcast! Thanks for having me. open.spotify.com/episode/2oIC...

😍 looks amazing!

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

Very excited to speak about circadian digital twins at this workshop today and tomorrow! www.nhlbi.nih.gov/events/2025/...

Had a ton of fun chatting with my friend Rosy on Science of Slink about SLEEP GROOVE + why sleep regularity is so important

Paraguay recently adopted permanent Daylight Saving Time. Less than a year later, citizens demand permanent Standard Time, to restore morning sunlight.

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

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

So proud of the team at @arcascope.bsky.social for all the new stuff we've gotten into Arcashift, our circadian-rhythms-everything app. Here's 5 features you might not know about that are either out right now, or coming in the next release:

Got zero sleep last night? Maybe you tossed and turned until morning came. Well, you're not alone, but there may be a way to ensure you get a good night's rest. Listen to our latest podcast extra where sleep researcher Olivia Walch talks about her new book, Sleep Groove. lnk.to/whyy-thepulse

SLEEP GROOVE, my love letter to circadian rhythms and sleep regularity, is out today! We need the rhythmicity of sleep to be just as central to how we define sleep health as the rhythmicity of your heartbeat is to defining cardiac health

I WISH I could go see @oliviawalch.bsky.social talk about her new book with @walthickey.bsky.social but you definitely should if you're local!!

DC! Come to this!

Me and @walthickey.bsky.social will be talking SLEEP GROOVE tomorrow night in Arlington at One More Page Books; it will be fun: www.onemorepagebooks.com/event/celebr...

"Sleeping is like pouring yourself a glass from a water cooler that's either tilting towards you (during biological night) or away from you (during biological day)" = two-process model in disguise

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?

Today's a great day to check out Gonzalez-Aponte et al in the most recent issue of Cancer Cell, where they report that timing of dexamethasone can either accelerate or slow down glioblastoma growth, depending on when it's given: www.sciencedirect.com/science/arti... x.com/oliviawalch/...
