The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
The difficulty lies in tissue specificity. So peripheral blood is easy going to buccal swabs are easy because they're accessible. But you know, you really probably want to know how many senescent astrocytes you have in your brain, and you know, brain biopsies are not going to be approved very soon.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
So you can you can stain these blood cells and get a sense of what your DNA damage load is. There are good markers for senescent cells now.
Is there a correlation between let's say, if you were to look at cellular senescence in white blood cells or leukocytes between that and the heart or the brain?
