Cancer cells excel at evading detection, but subtle chemical differences set them apart from healthy cells. Now, a team of ...

Scheme showing the structure of cytosine, 5-methylcytosine, and 5-hydroxymethylcytosine. Adding a methyl group to the DNA base cytosine represses gene expression in mammalian cells. To remove the ...

Scientists have taken a major step toward mimicking nature’s tiniest gateways by creating ultra-small pores that rival the dimensions of biological ion channels—just a few atoms wide. The breakthrough ...

DNA is the blueprint of life. Genes encode proteins and serve as the body's basic components. However, building a functioning organism also requires precise instructions about when, where, and how ...

Othram scientists work in a Texas-based lab to build genealogical profiles of missing people and crime suspects. In 1992, Pittsburgh Police and River Rescue recovered a man’s body from the Allegheny ...

For decades, the Golden State Killer avoided capture despite leaving DNA at multiple crime scenes. Traditional databases failed, fingerprints led nowhere, and the case went cold. Everything changed ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...
