Today marks a meaningful milestone for LABS β€” our SleepChart paper, β€œSleep chart of biological ageing clocks in middle and late life,” is now online in @Nature.
In this work, we link sleep patterns with biological aging clocks across the brain and body, highlighting how sleep may reflect broader systemic aging processes.
Key takeaways:
🧠 Sleep and biological aging clocks show a coordinated brain–body U-shaped pattern; this relationship extends beyond the brain alone and involves multiple organ systems and at multiple omics layers.
🧬 Sleep disturbances are linked to disease risks and shared genetic architecture: Short sleep appears to have a broader systemic impact, while long sleep shows a more focal, brain-enriched disease burden.
πŸ’€ Late-life depression provides an important example. Brain and adipose aging clocks mediate the relationship between long sleep and late-life depression, while short sleep appears to exert a more direct effect. As always, inverse causation cannot be fully excluded (potentially a sleep-LLD bi-directional relationship).

We are excited to share both the paper and the interactive SleepChart portal with the community (including GWAS summary statistics, etc.).

🫁 β™₯️ 🧠 πŸ«€ πŸ‘οΈ πŸ’ͺ πŸ‘‚ 🫘 Very happy to see our Pan-FM (Pan-FM: A Pan-Organ Foundation Model with Saliency-Guided Masking for Missing Robustness: arxiv.org/abs/2605.07055) was accepted at NeurIPS! Great work by Qiangqiang (Jimmy) Wu and the team!

Looking forward to connecting in December in Atlanta!

Happy to share our new @NatureMedicine paper on: "Sex-specific biological aging clocks across organs and omics"

As biological aging clocks have been rapidly developed in the research domain, we observed pronounced sex differences even in sex-pooled models in our previous work. So, here, we asked a very straightforward question: whether we should derive these clocks in a sex-stratified learning scheme? We found, in particular for a normative training scheme, that it's important to train the ML models separately so as not to mix the normative references between females and males. We confirmed substantial sex differences in downstream associations with genetics, omics, and disease endpoints among different organ systems/tissues (e.g., adipose tissue) and omics types. Thanks to all collaborators' contributions on this rapidly evolving topic! Thanks to all reviewers and the editors' work to make this online!

PS: We made all the sex-specific GWAS publicly available at: labs-laboratory.com/medicine/
