Age vs. genetics: Which is more important for determining how we age?
by Robert Sanders, University of California – Berkeley Age impacts the predictive power of eQTLs in many tissues. Credit: Nature Communications (2022). DOI: 10.1038/s41467-022-33509-0 Amid much speculation and research about how our genetics affect the way we age, a University of California, Berkeley, study now shows that individual differences in our DNA matter less as we get...

Zombie cells central to the quest for active, vital old age
by LAURA UNGAR This microscope photo provided by the Mayo Clinic in August 2022 shows senescent myoblast cells. Senescent cells resist apoptosis, or programmed cell death, and characteristically get big and flat, with enlarged nuclei. They release a blend of molecules, some of which can trigger inflammation and harm other cells — and paradoxically also...

Severe flu risk as immune cells swap with age
by Michael Keller, ETH Zurich AM and Mo-derived cells in influenza-infected mice. FeMo-reconstituted Csf2ra-/- and WT mice were infected with IAV (20 pfu PR8) as depicted in Fig. 2A. Representative gates and dot plots of BAL AM and BMo-Mac are shown on d10 and d21 p.i. Data are representative of at least 3 independent experiments with...

Age can impair a man’s odds for fatherhood: study
by Cara Murez It’s no surprise to hear that women’s fertility wanes as their biological clock ticks away. But do men have a biological clock, too? New research shows it’s not exactly the same, but their likelihood of fathering a child does appear to decline, even with assisted reproductive technology, once they’re past age 50. ...
