Lung inflammation
Six different aging clocks detected younger blood protein profiles in patients taking the experimental lung-fibrosis drug rentosertib. This suggests possible anti-aging effects, but separating those from the narrower benefits of treating fibrosis remains a challenge [1]. The AI-developed drug Many drugs developed for particular diseases act on aging-related biological processes. That creates an opportunity: a...
Grok Bot
With Grok Bot, SpaceXAi has created something really special and helpful. And the Evipedia Grok Bot turns this gem into something even more precious. A specialized AI assistant offering an evidence-based 2nd opinion on health and longevity interventions. It integrates Grok, the AI4L persona, the Evipedia MCP server, and Evipedia-hosted search into one super-useful companion. What Evipedia Grok Bot will do for...

Fresh from Spain’s spectacular victory in the 2026 FIFA World Cup, Madrid is preparing for another kind of world-class gathering: one focused not on winning more years of sporting glory, but on winning more healthy years of life. On September 30 and October 1, 2026, the International Longevity Summit Madrid 2026 will bring together leading...
Weak muscles
Researchers have discovered and explained how calcium mishandling in muscle cells leads to long-term muscle weakness in older people. Calcium is not just for bones Skeletal muscle cells use calcium ions to control how and when they contract. This activity is modulated by CaMKII, a protein kinase that also regulates muscle adaptations in response to...
DNA clock
In a recent study, researchers have evaluated how responsive several DNA methylation (DNAm) biomarkers are to a range of longevity interventions [1]. Waiting too long Testing lifespan-extending interventions in humans has a major problem: it can take many years, or even decades, to see results. Nobody wants to wait that long. Therefore, it is essential...
Food-Ignoring Mouse
In a new study, semaglutide given late in life increased median lifespan in female mice by more than 12% and improved various health markers. Semaglutide’s effect possibly went beyond caloric restriction [1]. Old mice, new drugs GLP-1 receptor agonists, which act on a hormone that regulates insulin secretion and appetite, have revolutionized obesity treatment, showing...
