Scientists Create Programmable Bacteria

Posted by samzenpus on Sunday December 12, 2010 @09:54PM from the anti-coding-soap dept.

wilmavanwyk writes "In research that further bridges the biological and digital world, scientists at the University of California, San Francisco have created bacteria that can be programmed like a computer. Researchers built 'logic gates' – the building blocks of a circuit – out of genes and put them into E. coli bacteria strains. The logic gates mimic digital processing and form the basis of computational communication between cells, according to synthetic biologist Christopher A. Voigt."

  They're inserting synthetic genetic code (with known function) into E. coli that will allow individual bugs to respond in predictable ways to other bugs' chemical signals. So, for example, there is a known DNA sequence that encodes a protein that 'recognizes' signal. There is another sequence that encodes a second signal recognition protein. There is a third sequence that encodes a scaffolding that binds the two signal proteins (an AND gate), and it produces some chemical or enzymatic output. This output is often a small molecule other bacteria can then subsequently recognize.
  
  Once you have enough parts (that are found all over biology, and are slowly being annotated and dissected) you can start to create real computers.
  
  This is very much about passing information between individuals. The 'logic' gates are very much still analogue - in that they are leaky and really only useful at a statistical level, but they are working. But small molecules can act as the medium of transmission between two different individual E. coli in a way that very much resembles a computation.

  there is no need to deal with protein folding in silico - we know a LOT about proteins and how they work just from standard biochemical assays. There are literally tens of thousands of characterized molecules with known DNA sequences from which we can pick and choose useful sets - slightly modify if need be - and then recombine in novel ways inside a cell. And we can do it directly - without having to rely on some kind of directed evolution - which is quite slow. It is very hard to program a specific well-defined program into a phage - whereas the molecular biology to add features, protein sequences and other regulatory DNA to E. coli is trivial at this point. This is not about making a better immune system, it is about making one (or something else) that is entirely characterized and programmed - not one that must undergo thousands of generations of (difficult to control for) selection in order to become useful.
  
  ...not to calculate anything fancy.
  Again, because we can program any arbitrary code into the bugs, it is trivial to make a bacteria that lights up green when it detects particular chemicals. Or that only grow when you have a fever, or that do other similar calculations. There are of course extreme difficulties when you're talking about therapeutics because you're interacting with the human body. But outside the human body it is only a matter of time before you start seeing bacterial sensors on everything. They are cheap, they are robust, and they can enzymatically recognize certain properties that mechanical sensors may have great difficulty doing, or doing rapidly, or cheaply. And when you can link the sensors with a programmable logic, THEN you get the really cool stuff. This research demonstrates the first steps into getting the programmable logic up and running.

Instead of having bugs in our programs, we are going to have programs in bugs. What would happen if it supports recursion? Is it possible we humans have been looking down the call stack instead of up? OMG indeed. OMG is just one step up the call stack! OMG'sG!!!!

This is definitely news for nerds, but this phrase in the summary got me wound up:

Aargh! Surely someone who doesn't know what a gate is wouldn't be reading slashdot?

DNA Encryption by MillionthMonkey · 2010-12-13 05:25 · Score: 1

The ability to encode arbitrary information in DNA has applications in security and encryption.

Let's say Alice wants to send a plaintext message to Bob. Except with DNA it's always Bob sending plaintext DNA to Alice. OK I have to correct a little bit and replace "Alice" with "Bob" and "Bob" with "Alice"... eh, that didn't work because it replaced all the strings with "Alice".... ctrl-Z ctrl-Z ok let's do this right... first replace "Bob" with a swap like "Sue"... replace "Alice" with "Bob"... wait a second, Bob is sending his DNA to Sue. OK that's fine with Bob and Sue except halfway through the final replacement, Alice is going to find out that Bob has been sending DNA to Sue. How can we effectively hide this information from Alice? Start the swap by replacing "Alice" with "Peter". Oh no that really causes problems because still, Alice will start to wonder about Bob.
