"I was not yet asleep, being a night owl." Nobel Prize winner Karl Deisseroth in first reaction after winning 🦉
BREAKING NEWS
The 2026 #NobelPrize in Physiology or Medicine has been awarded to Karl Deisseroth, Peter Hegemann and Georg Nagel “for their discoveries concerning light-gated ion channels and optogenetics.”

Do people differ in the max-min of daily rhythms in gene expression? This question, avoided for a long time, now tackled in this #JBR paper. Answer: YES! Personal transcriptomes differ in circadian amplitude, even among healthy folks. @SRBR_Outreach journals.sagepub.com/doi/ful…
“Strong evidence suggests that nonvisual opsins affect mood regulation and our daily biological rhythms.” @elaberwarren @SamerHattar #circadian knowablemagazine.org/content…
Amazing time at #SLEEP2026 hosted by @AASMorg @ResearchSleep in Baltimore. More than 5,000 attendees! Grateful for the many discussions about #DSPD #Non24 #circadian #sleepdisorders and #patientadvocacy

Today is #WorldCircadianDay!
Our circadian clocks influence our health. From sleep and metabolism to mood, cognition, and performance. By understanding and respecting our biological rhythms, we can improve health and well-being every day.

How animals sense Earth’s magnetic field is one of biology’s enduring mysteries.
Researchers in Science have now identified superparamagnetic macrophages in the livers of rock pigeons to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation.

Sleep is vital for brain development—especially in children with neurodevelopmental disorders. Disruptions can affect brain function, hormones, metabolism & inflammation, potentially worsening conditions like autism & ADHD. More research = better care. #SleepScience #Neurodevelopment

New paper out by @MarcoFerr_. We developed a new high-throughput live imaging platform to monitor circadian rhythms in up to 144 brain tissues. We are now using it to screen chronotherapeutics for Alzheimer directly in brain tissue. Exciting times! @UKDRI doi.org/10.1002/advs.75427

Mental health disorders are closely tied to circadian rhythm disturbances.
Night owls have an 83% higher depression risk.
Being a morning type seems to be protective.

Research highlight from #JBR!
Clock genes (Bmal1, Per1, Per2) show ~24h rhythms in the dorsal & median raphe of rat brains, suggesting serotonergic systems have intrinsic circadian clocks. This points to a link between clocks and mood-related circuitry: journals.sagepub.com/doi/10.…
Celebrating #WorldSleepDay - hosted by @_WorldSleep - with the theme of 'Sleep Well, Live Better.' People living with DSPD & Non-24 may be as prevalent as 1 in 600. More research in Circadian Rhythm Disorders is desperately needed. 🔬🧬☀️🌒

Author @HaleyShapley contacted @CSD_N about input for the book NIGHT OWL. It will explore the science of chronotypes, the history of the night owl stigma and solutions for society to be more inclusive of a range of sleep-wake cycles. EVP @AlexWharton spoke with Shapley about CSD-N's mission to increase awareness of DSPD & Non24 and decrease the time to proper diagnosis.
➡️ NIGHT OWL is scheduled to be published by @MacmillanUSA @StMartinsPress in March 2027.

A clock in a bottle? By reconstituting cyanobacterial clock machinery in vitro, researchers uncovered how these biological clocks precisely switch gene expression on and off! @susanksgolden

"It isn't being a night owl that's a problem," Dr. Kristen Knutson of @NUFeinbergMed said. "I think being a night owl who's trying to live in a morning lark's world is a conflict between one's internal clock and their social clock." #chronotype #nightowl 🦉abcnews.go.com/Health/night-…

ADHD is a circadian rhythm disorder.
We just published a new paper on the topic.
frontiersin.org/journals/psy…
Circadian rhythm dysfunction is highly prevalent in ADHD
Up to ~75% of patients have delayed sleep and wake timing, and shifting the clock earlier is linked to symptom improvement
I just published a paper on what this means for treatment. Here’s what we found 🧵1/12

Nov. 24 is Non-24 Awareness Day! It's a neurological sleep disorder in which a person's sleep/wake cycle is longer than 24 hours. The person is unable to adjust their sleep/wake cycle to the length of the day, and their sleep time progresses around the clock. #circadian #non24
