Tardigrades belong to the most radiation tolerant animals on Earth, as documented by a number of studies using both low-LET and high-LET ionizing radiation. Previous studies have focused on semi-terrestrial species, which are also very tolerant to desiccation. The predominant view on the reason for the high radiation tolerance among these semi-terrestrial species is that it relies on molecular ...

Diamond is used as detector material in high energy physics experiments due to its inherent radiation tolerance. The RD42 collaboration has measured the tolerance of chemical vapour deposition (CVD) diamond against proton, pion, and neutron irradiation. Results this study are summarized article. detectors can be further enhanced by using a 3D electrode geometry. We present preliminary results p...

In living cells, reactive oxygen/nitrogen species (ROS/RNS) are produced as the byproducts of metabolic processes during aerobic respiration or during growth under unfavorable conditions. Organisms have evolved different strategies, involving both antioxidant enzymes and non-enzymatic antioxidant molecules to detoxify these species. These reactive molecules, if not detoxified, can cause oxidati...

The Radiation Hardened Electronics for Space Environments (RHESE) project consists of a series of tasks designed to develop and mature a broad spectrum of radiation hardened and low temperature electronics technologies. Three approaches are being taken to address radiation hardening: improved material hardness, design techniques to improve radiation tolerance, and software methods to improve ra...

Tardigrades inhabiting terrestrial environments exhibit extraordinary resistance to ionizing radiation and UV radiation although little is known about the mechanisms underlying the resistance. We found that the terrestrial tardigrade Ramazzottius varieornatus is able to tolerate massive doses of UVC irradiation by both being protected from forming UVC-induced thymine dimers in DNA in a desiccat...
