What if we had therapies to extend healthspan and prevent the onset of age related diseases? I’m excited to announce my first @ARPA_H program, PROSPR. The goal is to develop validated surrogate biomarkers, new clinical endpoints and therapies to collectively extend healthspan by 20 years for all Americans.

What if we could predict age-induced health issues before they happen? Our new PROSPR program aims to identify biochemical and physiological markers, paving the way for faster, more targeted aging research. arpa-h.gov/news-and-event…

A medicine is only helpful if you take it. The benefits of exercise and healthy living are clear. The reality is that far too few people do it. As someone who wants to maximize healthy lifespan for every person we need additional solutions.

The boxer my father named me after, Alexis Arguello, was the world's first 3-weight world champion before facing an opponent who cheated. Boxing is only great when it's fair, and @jabbr.ai is here to make it so!

Various ways to think about aging, roughly in order of when they became popular: 1. Longevity 1.0: Target the well conserved pathways (mtor, foxo3, ampk etc) and their regulators. 2. Longevity 2.0 The SENS/Hallmarks view: Remove damage, typically concrete molecular entities or cells, as well as adding back what was lost (like stem cells) 3. Longevity 3.0: Organisms can mostly fix their aging if they tried, they just 'forgot' how to or are "stuck" in some way (information loss (Sinclair), loss of morphostasis (Levin)) so what's needed is to nudge them in the right direction (e.g. reprogramming) and they can sort the rest out. None of these are "true" or "false", they are all incomplete, but I think of them as useful.

@KarlPfleger I was poking fun based on your claim that you had a more accurate measure. I’m good on wherever your analysis places me.

@BrackLab Sorry to disappoint but it's alphabetical within the large coarse overall scores. So you are one of N people with a score of X whose last name happens to start with B. The ranking is not meant to be a good one. Just to separate out people into generally high vs mid vs low.

YES!!!! I’m 148th on the objective measures longevity list. Hopefully I’ll break top 100 next year😂
Karl Pfleger@KarlPfleger

@Longevity_Now_ Better longer list, much based on objective measures: AgingBiotech.info/people Note: Altman & Kurzweil not even on it despite being 250+ long. Altman funded 1 company w/o being very involved. He's busy w/ AI. Poor pick. Kurzweil had vision long ago but not really in the field.

@RapaNews This points to the selection criteria of why these compounds were tested-when resources are limited. Personally, I’m not surprised at all. Who advocated for these?

A very important point is the safety point: this paper shows you can significantly decrease myostatin levels throughout a person’s lifetime, and the result is more muscle, less fat, increased strength, and no noticeable side effects

Humans with function-disrupting variants in the myostatin gene (MSTN) have increased skeletal muscle mass and strength, and less adiposity nature.com/articles/s4146…

ARIA
ARIA@ARIA_research·
The search for ARIA’s next cohort of Programme Directors has begun 🚀 As an ARIA PD, you will design and actively manage a ~£50M R&D programme within or around our opportunity spaces with the goal of unlocking scientific and technological breakthroughs that benefit everyone. There is no one way to be an ARIA PD – our existing cohorts come from a range of backgrounds, including academia, entrepreneurship, invention and industry, and have launched programmes in areas ranging from synthetic plants to multi-agent coordination to brain surgery-free neurotechnologies. Full applications will open in August 2026 for a May 2027 start date – over the coming months we’ll be running webinars and in-person events across the UK, Europe, the US and Asia where you’ll get the chance to engage directly with the ARIA team and learn more about the opportunity. Find out more about what it means to be a PD and register your interest to be the first to receive updates on the recruitment process: link.aria.org.uk/pdc3-x

I think, you and I are aligned on the approach, my point is that we dont have the n of 1 positive control, and im not sure there is such a thing. We need to build a new infrastructure, a US biobank with emphasis on longitudinal collection for RWD. Happy to chat in more detail about building.

@BrackLab @bryan_johnson why low n? I think you can do home blood draws and make it pretty cheap. Bryan would agree with that too -- he's just been doing n of 1 b/c he's been willing to pay for it. But no reason can't make it cheap now.

Thanks for enganging @jrkelly. Agree with you that constant molecular monitoring -longitudinal measures, is going to be a huge unlock, and when combined with long term health outcomes, but we need to build that data layer out. In line with your passion for lab automation, noise and low n is going to limit interpretations. Bryans focus on his own n-of-1 as a standard of which to map against, with interventions of somewhat unknown utility and to monopolize, is why it’s wrong. But happy to chat about automation of the n of 1 for longevity anytime. We are all living our own adaptive clinical trial.😉

hit me! what don't you like? my general theory is we should be doing as frequent as possible measurement of tons of biomarkers in at least blood. Oura ring but for molecular measurement. Then can do various interventions and see what works -- also likely to get early detection signals of various diseases over time if lots of people start doing this. Easy way to get started IMO is frequent blood collection sent to central labs for broad metabolomics, proteomics, etc.
