Lifespan.ioA new study suggests that aging or Parkinson's-triggering mutations spark inflammation in body tissues first. Circulating extracellular vesicles then carry that inflammatory signal into the brain, potentially seeding neurodegeneration.
Peter AttiaAttia's AMA #86 tackles the muscle-loss concern around GLP-1 receptor agonists (a class of weight-loss drugs including semaglutide). His take: with adequate protein and resistance training, lean mass loss appears minimal.
Lifespan.ioScientists linked disrupted calcium signaling to aging in multiple mouse models. Correcting it with a repurposed antidepressant raised both median and maximum lifespan in the animals.
BluePrint (Bryan Johnson)Bryan Johnson outlines the four protocols behind his cardiovascular metrics, which score better than 90% of 18-year-olds. The post covers measurable markers and the lifestyle stack behind them.

Lifespan.ioLimiting food access to an 8-hour window raised median lifespan in male mice by 12%. Researchers note the effect may reflect voluntary calorie reduction rather than fasting timing itself.
Fight Aging!Researchers mapped senescent and disease-associated microglia in aged mouse brain white matter and showed targeted senolytic treatment could reduce them. The work points toward new entry points for brain aging intervention.
Nature AgingA Nature Aging study found that trained human muscle shows delayed molecular aging and preserved energy metabolism. Researchers also found a stronger exercise response — suggesting regular training actively counters aging at the molecular level.
Lifespan.ioNew research maps the molecular links between age-related muscle loss (sarcopenia) and bone loss (osteoporosis). The findings open potential shared intervention points for both conditions.
Research VialsA review of the leading peptides studied for immunomodulation — Thymalin, Selank, LL-37, KPV, and their distinct immune pathway targets.
Fight Aging!A new analysis focuses on the link between epigenetic aging and senescent cell accumulation in intervertebral discs. The work adds to growing evidence that disc degeneration is driven by systemic aging processes, not just mechanical wear.
Nature AgingNature Aging reports that blocking interleukin-11 (an inflammatory signaling protein) slowed ovarian aging markers in a preclinical study. The finding adds ovarian longevity to the growing list of tissues where IL-11 inhibition shows promise.
Fight Aging!A new open-access paper argues that therapeutic plasma exchange and partial epigenetic reprogramming could work better together than either approach alone. The logic: they target complementary drivers of aging.
Lifespan.ioResearchers used a protein-interaction network approach to predict which approved drugs may extend human lifespan. The method gives longevity researchers a faster way to identify repurposing candidates.
BluePrint (Bryan Johnson)Bryan Johnson reviews the science behind skin aging and explains which actives passed his evidence filter. The post is a useful reference for anyone evaluating anti-aging skincare claims against actual data.
Research VialsPart two of Research Vials' cancer series covers how tumors spread and how the immune system tries to stop them. It then maps the first wave of peptides studied for interference with these processes.
Research VialsThe final installment tackles the most pressing practical question: what does the research say about GH secretagogue use in subjects with cancer history or risk? Washout data and risk stratification are covered in depth.
