DNA stores information

We already know that DNA stores information for most living organisms. Our current electricity-based computing systems store and process info by setting two commands: on and off (translated to ones and zeros in binary code)...

DNA swap in babies

British scientists have made a huge leap in tackling incurable conditions - by swapping the DNA of babies before they are even born. The technique, which could be here within three years, could help wipe out serious inherited disorders which can lead to blindness, heart problems and early death. The research focuses on DNA in mitochondria - bean-shaped bodies in cells that act like batteries to generate energy.

Nobel prizewinner

A Nobel prizewinner is reporting that DNA can be generated from its teleported "quantum imprint" A STORM of scepticism has greeted experimental results emerging from the lab of a Nobel laureate which, if confirmed, would shake the foundations of several fields of science. "If the results are correct," says theoretical chemist Jeff Reimers of the University of Sydney, Australia
