Cells working with an expanded genetic code could make more diverse medicines. A new study shows scientists are within striking distance. One of modern biologists' most ambitious goals is to learn how ...

Scientists sought to work out genetic errors by creating their own artificial genome, which replaced E. coli’s original genome and used less genetic material.

Proteins that were present during the origin of life may have consisted of only seven primordial amino acids, a study suggests. The 20 amino acids commonly found in proteins are encoded by a total of ...

It has been thought that one gene sequence codes for one protein (though the cellular machinery can make variations of that protein through a variety of mechanisms) as described in the video. Now ...

DURHAM, N.C. -- A new examination of the way different tissues read information from genes has discovered that the brain and testes appear to be extraordinarily open to the use of many different kinds ...

From the beginning of its history the Royal Society has devoted much attention to the publication of communications by its Fellows and others. Within three years from the granting of the first Charter ...

Well begun isn’t always half done. Sprinters can stumble after they’ve taken a few strides out of the starting blocks. Car engines can stall after they’ve turned over a few times. And recombinant ...
