Peter Attia reviews new data on GLP-1 receptor agonists (drugs like semaglutide used for weight loss) and lean mass loss. He argues that proper protein intake and resistance training largely cancel out the muscle loss concern.

New research lays out the biological pathways that link sarcopenia (age-related muscle loss) and osteoporosis (bone loss). The two conditions share signaling crosstalk — meaning treating one may help the other.

A new study used a network approach to match approved drugs to the known biological drivers of aging. The method flags repurposing candidates that could extend healthspan without waiting for novel drug approval.

A review summarizes how gut bacteria influence both muscle and brain aging — and why restoring a younger microbiome profile in animal studies consistently slows decline in both tissues.

Bryan Johnson outlines four cardiovascular protocols with published evidence behind them. His blood pressure now tests lower than 90% of 18-year-olds — a concrete, trackable result worth examining.

Senescent cells accumulate rapidly after a heart attack and make tissue damage worse. The finding suggests there may be a treatment window right after cardiac injury where senolytics could reduce long-term dysfunction.

Researchers found a non-coding RNA strand — a piece of genetic material that doesn't make proteins — that is unique to primates and makes cellular senescence worse. The finding opens a new target for human-specific anti-aging research.

A new study tracked how individual cell types age at different rates and found those trajectories could predict when diseases like Alzheimer's and lung cancer would appear. Cell-specific clocks are more precise than whole-tissue aging markers.

Peter Attia examines a new meta-analysis on sleep loss and mortality risk. He explains what the data can and can't prove — and why the practical takeaway still points firmly toward protecting sleep.

Part one of a three-part series covering cancer biology fundamentals. The focus is on which signaling pathways tumors exploit — and why that matters for understanding where peptides might fit.
