LONDON – In a landmark decision that some ethicists warned is a step down the path toward “designer babies,” Britain gave scientists approval Monday to conduct gene-editing experiments on human ...

In an unprecedented leap in scientific discovery, a new lifeform has been constructed using a mere 57 genetic instructions. This remarkable feat paves the way for boundless opportunities in biology, ...

Despite awe-inspiring diversity, nearly every lifeform—from bacteria to blue whales—shares the same genetic code. How and ...

More than a year ago, the world was shocked by Chinese biophysicist He Jiankui’s attempt to use CRISPR technology to modify human embryos and make them resistant to HIV, which led to the birth of ...

Tail loss in gorillas, chimpanzees, and humans is believed to have occurred about 25 million years ago, when the group evolved away from Old World monkeys. A genetic change in our ancient ancestors ...

The genetic code is a set of rules defining how the four-letter code of DNA is translated into the 20-letter code of amino acids, which are the building blocks of proteins. The genetic code is a set ...

Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific ...

Researchers have reconstructed a long string of genetic code for what they believe is the common ancestor of placental mammals — a shrewlike creature that lived in Asia more than 75 million years ago.

CRISPR is the basis of a revolutionary gene editing system. One day, it could make it possible to do everything from resurrect extinct species to develop cures for chronic disease. It’s built on a ...

DNA and RNA, the two major modern forms of genetic code underpinning all of earthly biology, could have coexisted in strict pairings on our planet before life arose here, scientists in England, ...

Johns Hopkins researchers have developed a powerful new AI tool called Splam that can identify where splicing occurs in genes—an advance that could help scientists analyze genetic data with greater ...
