Social stress can affect the way genes are expressed. A new study has found that epigenetic effects could explain why some people who experience trauma in childhood have an increase in the risk of ...

Add Yahoo as a preferred source to see more of our stories on Google. Stochasticity is everywhere -- and finding the order in disorder can unlock new ways to understand biology. Erlon Silva - TRI ...

Cancer is often seen as a disease that arises from genetic mutations causing cells to divide uncontrollably and invade other parts of the body. But the spread of cells away from their origins is ...

A large meta-analysis shows breastfeeding is linked to subtle DNA methylation differences in infants, suggesting a molecular ...

In a recent study published in the Science Advances Journal, researchers reported the link between aging, cancer, and epigenomic changes. Recent studies have reported that aging is a leading risk ...

DNA methylation marks have recently been used to build models known as epigenetic clocks, which predict calendar age. As methylation of cytosine promotes C-to-T mutations, we hypothesized that the ...

Epigenetic clocks provide a molecular framework for assessing biological ovarian age by integrating DNA methylation patterns with hallmarks of reproductive aging. While these clocks show moderate ...

Researchers assessed DNA methylation at 800,000 sites in the genome in blood samples collected from 900 people. The study includes extensive clinical information on participants, who all provided ...

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients experiencing the same infection. How can two people infected by the same pathogen ...

New research in C. elegans from scientists at Howard Hughes Medical Institute (HHMI) helps explain how changes in the parents’ lysosomes that promote longevity are transferred to their offspring.

As recently as the mid-20th century, aging was described by Nobel Prize laureate Peter Medawar as "an unsolved problem in ...
