Researcher Chris Dwyer, assistant professor of electrical and computer engineering at Duke’s Pratt School of Engineering, demonstrated that by simply mixing customized snippets of DNA and other ...

DURHAM, N.C. – In a single day, a solitary grad student at a lab bench can produce more simple logic circuits than the world's entire output of silicon chips in a month. So says a Duke University ...

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are ...

Phosphorus is fundamental to the chemistry of DNA, but a bacterial strain has been evolved that replaces some of that key element with arsenic.

Supercoiling and looping can transmit mechanical stress along the DNA backbone that can promote the separation of the strands of the double helix at specific distant sites, exposing the DNA bases, ...
