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 ...

In just a few decades, DNA sequencing technologies evolved from slow, manual processes to rapid, automated ones, making ...

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 ...

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 ...

Silicon chips have powered computing for half a century. Increasingly, they are also becoming platforms to read and ...

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 ...

A new method for recognizing and targeting DNA that dramatically expands the range of genetic sequences scientists can identify has been developed by experts at the University of Portsmouth. Published ...

Emerging methods are improving the ability to identify even highly degraded human remains. By Damien Cave Reporting from Hanoi, Vietnam The world is facing an abundance of tragic events that produce ...

Zettabytes—that’s 10 21 bytes—of data are currently generated every year. All of those cat videos have to be stored somewhere, and DNA is a great storage medium; it has amazing data density and is ...

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 ...
