DARPA (Defense Advanced Research Projects Agency) has recently launched what has been described by some as a sinister biotechnology project: "Generative Optogenetics" GO, a high-risk initiative, but claimed to be high reward project, engineered for producing intricately controlled light-burst signals that cause targeted and impacted living cells to write DNA and RNA. 

Described by DARPA as the "massless information transfer" it enables genetic material to be synthesized within hours through the light-burst signals, unlike lab-based genetic sequencing methodologies that take days.  

As DARPA claims:

"GO aims to create a molecular machine that can be expressed in living cells and provide a mechanism for transducing genetic information transmitted masslessly via optical signals into the nucleic acid sequences (DNA and/or RNA)."
