Association of Telomere Length With Risk of Disease and Mortality

Carolin V. Schneider, MD¹; Kai Markus Schneider, MD, PhD²; Alexander Teumer, PhD^3,4,5; et al

Conclusions and Relevance  This cohort study found that shorter LTL was associated with a small risk increase of overall mortality, but a higher risk of mortality was associated with specific organs and diseases.

Conclusions

This cohort study, which to our knowledge is the largest study of telomere length, found that LTL is associated with specific human diseases and organ manifestations. In particular, individuals with short LTL were susceptible to similar disorders as participants with inherited telomere diseases, suggesting that LTL may contribute to specific illnesses irrespectively of the biology of different genetic variants. However, an association study cannot distinguish between causes and consequences. Shorter LTL may indicate a stressed bone marrow rather than per se predisposing to hematologic disorders. Further studies are needed to identify the underlying mechanisms and to delineate the relative contribution of genetic vs lifestyle-related factors.

Yet omicron thrives despite — or maybe because of — these mutations. Carl Zimmer explains why for The New York Times. Understanding the evolutionary “fitness landscape” of coronavirus mutations is vital to anticipating what new variants might pop up in the future. Earlier this month, Carrie Arnold reported for Quanta on researchers’ efforts to predict what SARS-CoV-2 might become next. Baby Games Scientists used game theory to model how trends in baby names evolve. The popularity of names ebbs and flows, never quite reaching a stable equilibrium, Gabe Allen reports for Discover Magazine. Traditional game theory predicts that every game will eventually reach an equilibrium. But in 2017, Erica Klarreich reported for Quanta on how the injection of variability in players’ goals and knowledge complicates this naïve prediction.

#The Marginalian M Popova Highlights in Hindsight: Favorite Books of the Past Year Trees, hummingbirds, snails, Stoicism, storytelling, Orwell’s roses, the crucible of consciousness, the end of the universe, and more trees. BY MARIA POPOVA I used to assemble annual reading lists of favorite books published each year —never an objective claim of bests, always a subjective inner library catalogue of my readings and rivets. But over the years, as I grew more and more interested in the river of thought and time that has carved out the island of now, I found myself spending more and more time in archives, perusing increasingly older books, reading fewer and fewer of the new — partly because such are my subjective passions (of which The Marginalian has always been a record and reflection), and partly because our present culture seems to treat books as little more than printed “content” (that vacuous term by which we refer to cultural material and thought-matter online), self-referential and preying on the marketable urgencies of the present. With each passing year, more and more books seem to be written and sold as commodities than composed as torches of thought and feeling for our own epoch, but also for epochs to come./.../
