Damaged DNA can escape from one human cell and infiltrate another. Like prisoners tunneling out of jail, this DNA travels via tubelike structures between neighboring cells, scientists report May 19 in ...

Humans are closely related to chimpanzees and bonobos, but what are the key factors that make humans genetically different? A new study looks at the process of DNA methylation, in which chemical tags ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...

In the never-ending battle between bacteria and viruses, both sides devise devious strategies to thwart the other. In a new study, scientists analyzed one such strategy used by the bacterium ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

“The laws of inheritance are quite unknown,” Charles Darwin acknowledged in 1859. The discovery of DNA’s shape altered how we conceived of life itself. The X-ray crystallography by Rosalind Franklin ...

Is it the invasion of the genome snatchers? Just in case the idea of aliens walking around in human skin suits wasn’t frightening enough. An outlandish study asserts that aliens might have abducted us ...
