DNA preservation on cave walls is highly variable, but scientists say their work is an important step on the path toward ...

Every cell type in the human body carries the same approximately 3.2 billion base pairs of DNA, yet a liver cell behaves nothing like a neuron. The epigenome explains this difference: in each cell, ...

DNA methylation is a key epigenome component that helps dictate how genes are expressed, contributing to normal cell and tissue differentiation during development, as well as the process of biological ...

An international research team has recovered ancient human mitochondrial and nuclear DNA directly from cave wall materials in ...

Differences in the pattern of a biochemical modification called DNA methylation in blood-generating cells and their progeny can be used to accurately track clones through differentiation. This ...

Duke University Medical Center-led research has identified a human-specific DNA enhancer that regulates neural progenitor proliferation and cortical size. Small genetic changes in HARE5 amplify a key ...

Collaborating researchers have made a breakthrough discovery regarding the intricate defense systems of bacteriophages (phages)—viruses that can specifically target harmful bacteria without harming ...

The DNA in a single cup of water can track wildlife, monitor pollution and survey pathogens in waterways and their ...
