DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

A groundbreaking DNA study has unveiled a hidden chapter in human evolution, revealing that all modern humans evolved from two ancient and distinct groups. This research, published in March 2025, ...

Ancient DNA reveals that childhood viruses lived with humans for thousands of years, reshaping how we understand human and ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

James Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped launch a revolution in biology and medicine, died Thursday at age 97. He died in hospice care after a brief ...

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 ...

When Neandertals were first discovered nearly 170 years ago, the conceptual gap between their lineage and that of modern humans seemed vast. Initially scientists prejudicially believed that the ...
