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 ...

Our brain is arguably the organ that most distinguishes humans from other primates. Its exceptional size, complexity and capabilities far exceed those of any other species on Earth. Yet humans share ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

What do your genes have to do with growing old? Quite a lot. But is it due to the actual DNA, or the way those genes are expressed? KPBS sci-tech reporter Thomas Fudge has more on new research that ...

We know the genes, but not their functions—to resolve this long-standing bottleneck in microbial research, a joint research ...

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 ...
