Honored to be named one of TIME's 2026 Longevity Leaders! Leading @XPRIZE Healthspan means chasing big questions: How do we measure aging? Slow it? Separate real science from hype? The work is just beginning. Thanks @TIME & @AlicePark 👇 #XPRIZEHealthspan time.com/collection/longevit…

Breakthroughs in the lab mean nothing if they can't reach patients. Our panel on Translating Geroscience is tackling the critical pipeline from discovery to clinic — and what it will take to get there. Moderator: Hanadie Yousef Panelists: @agingup, David Gobel, @mkaeberlein – at Washington, DC

I’m seeing some dangerous trends in “longevity medicine” and biohacker culture as doctors, pharmacists, and influencers push the edges of what’s legal and ethical. Here’s one example 👇 Unscrupulous marketers are selling research-grade chemicals while packaging them to look like benign dietary supplements. That design choice isn’t accidental. It’s meant to make people think these compounds are safe, tested, and appropriate for human use, when many are not. SLU-PP-332is a good case study. Despite sometimes being called a “peptide,” it’s actually a small-molecule drug with no human safety or efficacy data. It has only been tested in a handful of mouse studies. Yet it’s being promoted as an “exercise mimetic,” and some clinicians are even illegally prescribing it. Do a quick Google search and you’ll find plenty of sketchy sites selling “research-grade” SLU-PP-332. Don’t buy it. If you wouldn’t take the brown Sigma-Aldrich bottle and sprinkle it on your yogurt, why would you trust the exact same chemical sold by a fly-by-night internet vendor, encapsulated with unknown purity and zero oversight? I tend to be libertarian when it comes to healthcare - people should be free to make choices about their own bodies if they’re fully informed. This isn’t informed choice. It’s deceptive opportunism that puts real people at risk. Choose evidence over aesthetics. Science over marketing.

🧠 New in GeroScience! “Age, glucose tolerance, and cognitive performance in female vervet monkeys” by Brett M. Frye (@brettmfrye) & Carol A. Shively (@1749_336) et al. Key insights: 📍In middle-to-older aged female vervet monkeys, age was strongly associated with higher fasting glucose, impaired glucose clearance, and reduced insulin area-under-the-curve. 📍Animals with worse glycemic control over time showed poorer executive function and a trend toward weaker working memory. 📍These findings highlight a link between metabolic aging and cognitive decline in a primate model, reinforcing the importance of metabolic health for brain aging. 🔗 rdcu.be/ePbFU #CognitiveAging #Metabolism #NonHumanPrimates #VervetMonkey #HealthyAging

Depression is not a “thing”. It is a label for a range of dynamic, energetic states that manifest across the body-mind unit.

Geroscience is reshaping medicine—targeting aging biology (via caloric restriction, metformin, rapamycin, senolytics) may delay multiple age-related diseases at once. A new @JAMA_current review explores the science, promise, and clinical frontiers.jamanetwork.com/journals/jam…
