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...

Eating a healthy diet within 12 h/day increases healthspan as healthy mice age. Sam Clever, Vicky Acosta, Carla Green, Joe Takahashi and Co also found this works to extend life, but only males on this diet. I feel healthier having read this. www.nature.com/articles/s43...

Claude kindly telling people to go to sleep at all times of day, seems not to have learned so well about daily rhythms: www.reddit.com/r/ClaudeAI/c...

I have long dreamed that my commute to work by bicycle would inspire others to ride. Today, I got coverage. Anyone inspired? www.timesnewspapers.com/webster-kirk...

Babies synchronize their daily rhythms to mom before birth! Work by @circatwenty4.bsky.social and colleagues. source.washu.edu/2026/04/when...

Ever wonder if a baby knows what time it is? This work by @circatwenty4.bsky.social and collaborators says that the fetus synchronizes its daily rhythms to mom before birth. tinyurl.com/yk3m8fx3 #SRBRa #circadian #chronomedicine

Congratulations to newly-minted Dr. Kia Barclay, @washu-endure.bsky.social alum! She gave a stellar PhD defense on the role of reactive micoglia in brain repair.

The U.S. administration released the FY 2027 Budget Request this morning, proposing deep cuts to science funding once again. While there are similarities in the proposed cuts between FY26 and FY27, the final FY26 appropriations show the impact of advocacy in action.

Intersects Arts of St. Louis hosted a brilliant "Cabinets of Curiosity" featuring @washu scientist-artist Dr. Duygu Ozpolat. Overcoming fear to find beauty in bugs.

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....

Check out the summary of our recent work on mapping brain communication.

Here's a nice #WashU summary of @circatwenty4.bsky.social recent @pnas.org paper where he introduces MITE to infer functional connections among neurons. source.washu.edu/2025/12/mapp...

New Year?! New Job! I’m excited to share that I will be joining Pomona College as an Assistant Professor of Neuroscience this year!! 🧠 Very grateful to all who have encouraged me along this path, and I'm looking forward to this next adventure in science. @pomonacollege.bsky.social

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.

Congrats KL Nikhil and collaborators on inventing MITE to map functional brain connections! Surprising take home: MITE reveals 5 cell types (based on their connectivity) in the mouse circadian clock which underlie the daily wave of gene expression. www.pnas.org/doi/10.1073/...

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...

Oh this is cool!

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.

Courtney Peterson, associate professor of nutrition, looks at how intermittent fasting and meal timing may benefit aspects of cardiometabolic health, including weight loss, blood sugar, blood pressure, aging, and even cancer prognosis.

Images showing baby Mohammad Al-Motawaq captured world attention last month. In Israel, they were used to support claims that mass hunger in Gaza does not exist.

First highlight... Senator Capito started of the discussion saying that the bill contains AN INCREASE for NIH. The details are not available, but the bill will be released ofter the hearing. This is not a done-deal, but it does show where the Senate is on a bipartisan basis.

🚨Very happy that my PhD work is now out in @nature.com! We discovered that evolution, by acting in the midbrain, shifted the threshold to escape in Peromyscus mice, to fine-tune defensive strategies in different environments www.nature.com/articles/s41... This was a truly collaborative effort! 🧵⬇️

“With these considerations, we expect to fund through the 4th percentile.” There it is, in black and white, the destruction of cancer research in the US.

When two related mouse species are faced with a scary visual shadow that appears to be approaching…PAG neurons in one say “run!” And in the other say “freeze!” Very cool findings. Congrats to the authors. Could evolutionary switches like this underlie nocturnal vs diurnal?

1/ Why do patients with late-stage cancer lose motivation & sink into apathy? 🔥 Our new Science paper shows chronic inflammation activates a cytokine-sensing brain circuit that lowers motivation. Huge team effort: Aelita Zhu, Sarah Starosta, Pignatelli & Janowitz labs! 🧵 🔗 doi.org/10.1126/scie...
