Analyzing Soft Errors in Linux on Cots SoCs Under Proton Irradiation (arxiv.org)
The increasing use of Linux on commercial off-the-shelf (COTS) system-on-chip (SoC) in spaceborne computing inherits COTS susceptibility to radiation-induced failures like soft errors.

Aging reactors need a concrete solution (u-tokyo.ac.jp)
It’s been known for some time that radiation impacts the structural integrity of concrete. However, until now the details of this were unknown. Researchers, including those from the University of Tokyo, can finally demonstrate what properties of concrete affect its structural characteristics under different neutron radiation loads. Their findings raise some concerns whilst reducing others; for example, quartz crystals in concrete can heal themselves, potentially allowing some reactors to run for longer than initially thought possible.

Chernobyl frogs exposed to radiation show no signs of stress or increased ageing (phys.org)
The radiation levels experienced by the frogs living in Chernobyl have not affected their age or their rate of aging. These two traits do not differ, in fact, between specimens captured in areas with high levels of radiation and those living in control areas without radiation. Nor have differences been found in the levels of corticosterone, a hormone associated with the response to stress, depending on the radiation received by these amphibians.
