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

The technique uses a long strand of DNA with a set sequence—the template—and a bunch of shorter, premade DNA molecules that can base pair with specific spots on the template—the bricks.

Researchers have been working on DNA-based data storage for decades, but a new template-based method inspired by our cells’ chemical processes is easy enough for even nonscientists to practice.
