DNA damage and mutation have different biological consequences. While most DNA damages can undergo DNA repair, such repair is not 100% efficient. Un-repaired DNA damages accumulate in non-replicating cells, such as cells in the brains or muscles of adult mammals, and can cause aging.
The devastating fires in Maui have caused at least 115 deaths, yet only 46 of those have been identified two weeks on from the blaze, police said Thursday. Hundreds of people remain unaccounted ...

Fingerprint brushes, for example, can retain the DNA they pick up and create contaminated evidence. In order to ensure there will not be a transfer of DNA on brushes, they should not be reused. [1] Each scene should get a new one. This tip is especially important in situations like homicide cases, where DNA is a crucial factor. Paying the extra ...
The rate of DNA repair depends on various factors, including the cell type, the age of the cell, and the extracellular environment. A cell that has accumulated a large amount of DNA damage or can no longer effectively repair its DNA may enter one of three possible states: an irreversible state of dormancy, known as senescence
Aug. 14—KAHULUI — The death toll from the Lahaina fire — America's deadliest in a century — was at 96 on Sunday while families visited a newly created Maui County Family Assistance Center ...
These reactive chemical species can reach DNA by diffusion and the bimolecular reaction damages the DNA (oxidative stress). Unlike direct DNA damage which causes sunburn, indirect DNA damage does not result in any warning signal or pain in the human body. The bimolecular reactions that cause the indirect DNA damage are illustrated in the figure:
