DNA is found inside the cells of every living thing. It’s protected in a part of the cell called the nucleus.

Unexpected slowdowns or spikes in this signal were often interpreted as knots in DNA. But now, a new study published Aug. 12 ...

Our ability to "read" DNA has made tremendous progress in the past few decades, but the ability to understand and alter the genetic code, that is, to "rewrite" the DNA-encoded instructions, has ...
