Rapamycin Exerts Its Geroprotective Effects in the Ageing Human Immune System by Enhancing Resilience Against DNA Damage

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
Using in vitro DNA damage assays in human T cells, ex vivo profiling of aged immune subsets and a small placebo‐controlled in vivo study, authors show that low‐dose rapamycin, a potent life‐extending mTOR inhibitor, enhances resilience against DNA damage in the human immune system.

Potential of Soils Natural Sorbents for Environmental Decontamination From 137Cs

open access: yesLand Degradation &Development, Volume 37, Issue 2, Page 779-789, 30 January 2026.
ABSTRACT This study addresses the existing research gap concerning the lack of integrated data on the role of in situ soil components in the long‐term fixation of 137Cs under natural, protected, and non‐agricultural conditions. The contamination of ecosystems by radioactive isotopes, particularly 137Cs, represents a considerable environmental hazard ...
