The internet has revolutionized global communications and now researchers at Stanford University are looking to provide a similar boost to bioengineering with a new process dubbed “Bi-Fi.” The technology uses an innocuous virus called M13 to increase the complexity and amount of information that can be sent from cell to cell. The researchers say the Bi-Fi could help bioengineers create complex, multicellular communities that work together to carry out important biological functions.

Cells naturally use chemicals to communicate with the chemical signals typically acting as both the message and the messenger. However, this method of communication is extremely limited in terms of complexity and bandwidth.

“If your network connection is based on sugar then your messages are limited to ‘more sugar,’ ‘less sugar,’ or ‘no sugar’” explains Drew Endy, PhD, an assistant professor of bioengineering. By separating the messenger and the message, Endy and Monica Ortiz, a doctoral candidate in bioengineering, have been able to greatly increase the amount of data that can be transmitted.

They chose the virus M13 to act as the messenger because when it infects bacteria, it doesn’t kill its host but makes itself at home indiscriminately sending out DNA strands that it reproduces within its host. The engineers are able to control these strands of DNA, so custom DNA messages can be wrapped within proteins produced by M13 and sent out to infect other cells. Once they arrive in a new host, they release the packaged DNA message…

Using DNA to store the message means that it can contain any sort of genetic instruction. M13 is known to have packaged DNA strands containing as many as 40,000 base pairs, which is far in excess of the majority of genetic messages of interest in bioengineering that range from several hundred to many thousand base pairs…

The researchers believe that their Bi-Fi biological internet could lead to the development of biosynthetic factories consisting of huge masses of microbes collaborating to produce complex fuels, pharmaceuticals and other useful chemicals. Even more exciting, the researchers say that with improvements, the technology could one day be used in more complex three-dimensional programming of cellular systems, such as the regeneration of tissue of organs.

Looks like one of those qualitative processes that could be as scary as useful. Why, oh why, does my poor brain switch into sci-fi plots starring Milla Jovovich?

The positive side no doubt is where the research bucks will go. I hope.
