(PhysOrg.com) -- An Indian hacker group called The Lords of Dharmaraja has laid claim to Symantec’s antivirus software code. Symantec, confirming the theft in an e-mail posted Friday, said the chunk of pilfered code ...
In the beginning, there were simple chemicals. And they produced amino acids that eventually became the proteins necessary to create single cells. And the single cells became plants and animals. Recent research is revealing ...

(Phys.org)—In 2014, the incorporation of two artificial letters of genetic code into the DNA of Escherichia coli gave the bacteria the distinction of becoming the world's first stable semisynthetic organism.
A team of Australian engineers has proven—with the highest score ever obtained—that a quantum version of computer code can be written, and manipulated, using two quantum bits in a silicon microchip. The advance removes ...

A code is a rule for converting a piece of information (for example, a letter, word, phrase, or gesture) into another form or representation (one sign into another sign), not necessarily of the same type.
In communications and information processing, encoding is the process by which information from a source is converted into symbols to be communicated. Decoding is the reverse process, converting these code symbols back into information understandable by a receiver.
One reason for coding is to enable communication in places where ordinary spoken or written language is difficult or impossible. For example, semaphore, where the configuration of flags held signaller or the arms of a semaphore tower encodes parts of the message, typically individual letters and numbers. Another person standing a great distance away can interpret the flags and reproduce the words sent.
