Part one of a three-part series on peptides and cancer covers how tumors start and which signaling pathways they exploit. It sets the biological foundation for the more applied discussions in parts two and three.

Lifespan.io's monthly digest covers June's standout longevity research. The Thalion Initiative — a new non-profit with broad ambitions — is among the highlights, alongside genomic-level aging interventions.

BPGbio released new findings supporting BPM31510, its candidate for primary CoQ10 deficiency — a rare disease where mitochondrial energy production fails. Regulators appear willing to engage with the data, which could open a path to Phase 3.

NeuroSense's PrimeC biomarker readouts suggest its drug may act on shared pathways across ALS and Alzheimer's. The finding adds weight to a growing view that neurodegenerative diseases aren't as distinct as their separate diagnostic labels imply.

A new study links accelerated biological aging to early-onset solid cancers. Each successive generation shows a wider gap — suggesting the trend is not just better detection but a real shift in how fast people are aging at the cellular level.

Researchers mapped aging trajectories at the level of individual cell types. The result: disease onset for Alzheimer's and lung cancer can be predicted before symptoms appear. It refines how we think about biological age — not as one number, but many.

A non-coding RNA strand found only in primates appears to accelerate cellular senescence — the state where cells stop dividing but keep releasing inflammatory signals. The finding matters because it can't be modeled in mice.

Medtronic partnered with Corsano to bring continuous wrist-based biomarker monitoring into its US portfolio. The integration signals that medical-grade wearables are moving from consumer gadgets into healthcare infrastructure.

Bryan Johnson publishes the four cardiovascular protocols behind his vascular age scores. His blood pressure ranks below 90% of 18-year-olds. The protocols are data-driven and replicable — whether or not you buy the full Blueprint stack.

Part two of the Research Vials cancer series moves from biology to action — covering how tumors spread and which peptides researchers are studying as potential interventions at key checkpoints.

NeuroAge Therapeutics is running a six-month contest measuring participants on a clinical-grade aging panel at start and finish. It's an unusual way to generate real-world longevity data — and to market the platform simultaneously.
