It also increases the DNA damage that chemotherapy does to cancer cells by preventing the enzymes that normally repair such damage.
In one study he did in 1999, he found 11, 000 genetic changes in the DNA of colon tumors, indicating extensive DNA damage.
At the end of breastfeeding, the body has also been found to rid itself of any cells in the breast that may have DNA damage.
In addition, there was a reduction in the amount of DNA damage - errors that occur when a cell divides - seen in the three groups.
Beyond the usual tests, CHLI charts all sorts of extra parameters including three measures of arterial inflammation and an experimental test that looks in my urine for DNA damage.
Prof Vallis said "it is attracted to DNA damage", where it then delivers a dose of radiation, causing more damage and attracting even more antibodies - it is a "self-amplifying system".
To study the manifestation of the DNA damage we realize that there are competing causes of DNA damage and there may be non-DNA damage causes which contribute to the manifestation as well.
One possible explanation is that melatonin - a hormone produced at night - is suppressed in those working night shifts, having knock-on effects on oestrogen regulation in the body and protection against DNA damage.
Co-author Professor Sheena Lewis stressed it was not possible to say whether the DNA damage caused by diabetes would have the same effect on fertility as DNA damage caused by other factors such as smoking.
The study, which tracked 1000 patients in 16 countries for more than four years, was conducted by researchers from Queens University and Newcastle University in the UK. They focused principally on people with Lynch syndrome, an inherited genetic disorder that causes cancer by affecting genes responsible for detecting and repairing DNA damage.
FORBES: Study: Daily Aspirin Cuts Hereditary Cancer Risk in Half
But even more recently, chemist Vicky Colvin at Rice University showed that, while Fullerenes kill human liver and skin cells, they don't damage DNA and are non-carcinogenic.
Mitochondrial DNA is much more prone to oxidative damage (due to its nudity) than genomic DNA (11).
FORBES: Big Study Linking Chronic Fatigue To Virus May Be Fatally Flawed
However, the researchers managed to produce two healthy baby mice from heated sperm, and genetic analysis suggested that no damage to the DNA had been suffered.
These can be disrupted by damage directly to their DNA - but it's now been realised that epigenetic changes could also be responsible.
In spite of the fire damage, there are a number of ways DNA can be located on a body, Bernstein and Spitz said.
Sir2 can turn off whole swaths of genes inside cells, keeping the DNA coiled up in a protected position and less exposed to environmental damage during hard times.
