For nearly 15 years, a Texas death row prisoner has sought DNA testing that he claims will help to show he did not fatally stab an 85-year-old woman during a 1998 robbery. On Thursday, the Supreme ...

Curved tape measures are the standard for a reason. In terms of strength, stability, and versatility, they certainly have the edge. But of course, they're far from the only tape measure on the market.

Where would carbon-based life be without carbon? There are 118 known chemical elements, but carbon is the fourth most abundant and perhaps the most important to human life. Everywhere you look, ...

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.

To date, people have encoded information into DNA the same way nature has, by linking the four nucleotide bases comprising DNA—A, T, C, and G—into a particular genetic sequence.

DNA has tremendous potential as a data storage medium, but the process of synthesizing DNA from scratch is time-consuming. It has to be done one nucleotide at a time in a specific sequence.

"Distinct regulation of ATM signaling by DNA single-strand breaks and APE1," by Haichao Zhao, Jia Li, Zhongsheng You, Howard D. Lindsay, and Shan Yan in Nature Communications.

However, researchers say, most mutations have their origins in DNA changes that are present in only one of the two DNA strands, and these single-strand changes, such as a mismatched G and T base ...
