Exercise changes your DNA
You might think that the DNA you inherited is one thing that you absolutely can't do anything about, but in one sense you'd be wrong. Researchers reporting in the March issue of Cell Metabolism, a Cell Press publication, have f ...

Methylome modifications offer new measure of our 'biological' age
Women live longer than men. Individuals can appear or feel years younger – or older – than their chronological age. Diseases can affect our aging process. When it comes to biology, our clocks clearly tick differently.

Epigenetic causes of prostate cancer
(Medical Xpress)—In about half of all prostate tumours, there are two genetic areas that are fused with one another. When this is not the case, the exact way cancer cells originate in prostate tumours was not clear until ...

Evidence of biological process that embeds social experience in DNA that affects entire networks of genes
(Medical Xpress)—Early life experience results in a broad change in the way our DNA is "epigenetically" chemically marked in the brain by a coat of small chemicals called methyl groups, according to researchers at McGill ...
