Uncovering a 'smoking gun' of biological aging clocks

A newly discovered ribosomal DNA (rDNA) clock can be used to accurately determine an individual's chronological and biological age, according to research led by Harvard T.H. Chan School of Public Health. The ribosomal clock ...

Immune cells turn back time to achieve memory

Memory T cells earn their name by embodying the memory of the immune system - they help the body remember what infections or vaccines someone has been exposed to. But to become memory T cells, the cells go backwards in time, ...

Silencing of gene affects people's social lives, study shows

A team of researchers led by psychologists at the University of Georgia have found that the silencing of a specific gene may affect human social behavior, including a person's ability to form healthy relationships or to recognize ...

Study sheds light on the darker parts of our genetic heritage

More than half of our genome consists of transposons,DNA sequences that are reminiscent of ancient, extinct viruses.Transposons are normally silenced by a process known as DNA methylation, but their activation can lead to ...

Ancient epigenetic changes silence cancer-linked genes

An epigenetic change, a form of DNA control, that deactivates some genes linked to cancer late in human development has been conserved for more than 400 million years, new research led by the Garvan Institute of Medical Research ...

Genetics

A treasure map to understanding the epigenetic causes of disease

More than 15 years after scientists first mapped the human genome, most diseases still cannot be predicted based on one's genes, leading researchers to explore epigenetic causes of disease. But the study of epigenetics cannot ...
