#Circadian disruption is well linked to Alzheimer’s disease but how does it shape pathology?
In this invited editorial in SLEEP, I discuss Duncan et al.’s study showing that dim light at night reshapes microglial state and amyloid vulnerability.

Ten year survival in breast cancer patients TimeTeller predicted good or bad clock function shows good clock function is associated with shorter survival.
Good clocks are bad? Using TimeTeller we predict clock function and phase from breast tumour transcriptomes in a multi-cohort dataset including 1286 patients. We find that good tumour clock function is antagonistic to survival.
Now out as preprint: Vasilyev et al.

Satellites could disrupt #circadian rhythms globally. Major projects such as #ReflectOrbital and #SpaceX are pushing boundaries, and now is the time to recognise the effect these projects could have on life everywhere. www.bioclocks.uk/news

2026 off to a heavy start. Very sad news from Hanover: The European circadian and seasonal rhythms community lost an excellent physiologist and a genuinely kind human being. Stephan Steinlechner passed away unexpectedly in January.

Very happy to see this work published!
The result of 10 years of research across Switzerland, Australia and Denmark!

The time of day for cancer immunotherapy is associated with major outcomes. Early is better. Results from a randomized trial of lung cancer, backs up the importance of our circadian rhythm and immune system

SO HAPPY to share our new paper in @currentbiology.bsky.social! Using volumetric EM, we found daily shifts in synapses, vesicles, and mitochondria that accompany neuronal remodeling, linking structural plasticity to changes in how s-LNv neurons influence their targets

Beginning of Faust I
Excited to join the #UnderOneSky conference (Nov 7–8), organized by @darkskyintl.bsky.social to protect our natural night. 🌙
I’ll present findings from the ENLIGHT project on how #lightpollution affects amphibians, highlighting why preserving natural night conditions is vital for wildlife.
Socioeconomic roots of academic faculty
Tenure-track faculty are up to 25 times more likely to have a parent with a Ph.D. Moreover, this rate nearly doubles at prestigious universities and is stable across the past 50 years.

Canonical correlation analysis reveals five sleep-biopsychosocial profiles (LCs). Scatter plots showing correlations between biopsychosocial and sleep canonical scores. Each dot represents a different participant. The inset shows the null distribution of canonical correlations obtained by permutation testing; note that the null distribution is not centered at zero. The dashed line indicates the actual canonical correlation computed for each LC. The distribution of sleep (top) and biopsychosocial (right) canonical scores is shown on rain cloud plots.
Sleep is often only investigated from a single dimension. @bttyeo.bsky.social &co identify 5 sleep-biopsychosocial profiles that link self-reported #sleep patterns to variability in #health, #cognition & #lifestyle factors in 770 healthy young adults @plosbiology.org 🧪 plos.io/42tRXSc

Gerade gelernt: die Sommerzeit hat die DDR der Bundesrepublik rein gedrückt.
Im Osten war das allerdings als Experiment gedacht und sollte nach einem Jahr wegen Misserfolg wieder abgeblasen werden. Da stellte man sich im Westen dann quer. Das Abblasen wurde abgeblasen.
Around the equinox, we see an increased interest in how biological rhythms are affected by light. UK #Chronobiology academics have been communicating the research on this for over a decade now - check out this timeless podcast episode on rhythms: www.bbc.co.uk/programmes/b...
