Researchers explore a basic building block used in the fabrication of many DNA nanoforms. Known as a Holliday junction, this nexus of two segments of double stranded DNA has been used to form ...

For decades, scientists believed that DNA strands under stress would form knots, tangling into chaotic shapes. But new research led by the University of Cambridge shows otherwise: when put under ...

DNA’s iconic double helix does more than “just” store genetic information. Under certain conditions it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

Like its viral cousins, a somewhat parasitic DNA sequence called a retrotransposon has been found borrowing the cell's own machinery to achieve its goals. In a new work appearing online Wednesday in ...

In 1963, researchers unearthed two Stone Age skeletons that were buried in an embraced position in a cave in Italy. Now, DNA testing has revealed that one of them had a rare genetic condition.
