The visible effects of ageing on our body are in part linked to invisible changes in gene activity. The epigenetic process of DNA methylation — the addition or removal of tags called methyl groups — ...

A recent study examines why Alzheimer's presents and progresses differently in individuals using advanced biological analysis ...

Our DNA is made of millions of combinations of the genomes that create the human body. Even the smallest changes in these sequences, or in how they act, can change the functioning of the whole body ...

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

In a study published in Nature Communications, Mayo Clinic researchers have identified specific DNA-level changes in the brains of people with Alzheimer's disease (AD). Using advanced biological ...

Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health traits. By probing regions of DNA previously linked to disease, the work has ...
