A recent study investigated whether the body’s oxytocin system acts as a biological risk factor for Functional Neurological ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

Epigenetics has spent the past two decades promising to rewrite the rules of biology. The idea that chemical tags sitting on top of DNA can switch genes on and off, that these tags can be shaped by ...

Aging may "erase" the epigenetic markers that control gene expression in the brain, and this may snowball to cause unintended consequences, a new mouse study suggests. Tiny chemical messages attached ...

In a small study, Johns Hopkins researchers found that DNA from the sperm of men whose children had early signs of autism shows distinct patterns of regulatory tags that could contribute to the ...

Traits pass from parents to offspring through DNA, or so the standard picture of heredity goes. In tiny worms, a new study found an exception that lasted for generations.

The human body is composed of trillions of cells, yet we start as a single, fertilized cell that simply divides, over and over. As new daughter cells are created during development, it's crucial that ...

Parents pass their genes down to their kids, with a child inheriting about 50% of their genome from each parent. But there is another kind of genetic code known as the epigenome that can also be ...

The age on your driver's license may not be the same age as the cells in your body. Scientists use something called an epigenetic clock, which looks at certain chemical tags in DNA to measure your ...

For decades, obstetricians have drawn a bright line at age 35, labeling pregnancies beyond that threshold as advanced ...

Salk Institute researchers find new mode of epigenetic targeting, showing for the first time that genetic sequences can direct new DNA methylation patterns in plants LA JOLLA (November 21, 2025)—All ...
