How chromosome ends stay stable: telomerase's unexpected role in DNA replication fork breaks

This is a sophisticated mechanistic study that rewrites textbook telomere biology, but it's preliminary (preprint, in yeast) and needs independent replication before it should influence medical practice. For researchers: it's …

Blood Proteins of Centenarians Reveal Secrets of Extreme Longevity

This is solid discovery research that maps real molecular differences in centenarians with decent cross-study validation, but it identifies associations, not proven mechanisms. The findings are promising enough to guide …

How inflammation drives mobility loss in aging—and what we can do about it

This is a well-organized summary of how chronic inflammation drives mobility loss in aging, backed by solid mechanistic science. However, it's a literature review rather than new research, so while …
