VALINE RESTRICTION EXTENDS MALE MOUSE LIFESPAN 23% — MITOCHONDRIA ARE THE LEAD SUSPECT...
Lifespan.ioCutting one amino acid — valine — from mouse diets extended median and maximum lifespan by 23% in males. Both sexes showed healthspan gains. Researchers point to increased liver mitochondrial activity as the likely driver, though the exact mechanism isn't confirmed yet.

MONTANA RIGHT-TO-TRY REVIEW BOARD ADDS LONGEVITY HEAVYWEIGHTS — EXPERIMENTAL ACCESS EXPANDS...
Lifespan.ioMontana's first experimental treatment review board just brought three prominent longevity researchers into the state's framework for expanding access to unapproved therapies. The move is being watched closely as a potential model for other states navigating the tension between patient access and regulatory oversight.

NEW TRANSCRIPTOMIC CLOCK 'PASTA' PREDICTS AGE-RELATED COMPOUND EFFECTS WITH PRECISION...
Lifespan.ioA new tool called Pasta uses gene expression data — not methylation — to measure how compounds and gene changes affect biological age. Researchers say it outperforms existing epigenetic clocks for tracking intervention effects, which matters a lot for anyone trying to measure whether a peptide protocol is actually working.

EPIGENETIC CLOCKS DESTABILIZED BY SHORT-TERM STRESS — INTERVENTION DATA MAY BE NOISIER THAN THOUGHT...
Lifespan.ioMethylation-based clocks give consistent readings when inputs are stable — but short-term biological stressors can throw off the results. That's a real problem for researchers using clock readings to evaluate peptide or longevity interventions.
