Motivation
WORKING ON IT!
MISSING = WHAT IS EXACTLY THE SPECIAL THINGS THAT WE DID? DOUBLE PROMOTERS? BIOLOGICAL AUTOMATON WITH MEMORY? COOL WAYS TO EXPLAIN A BIOLOGICAL SYSTEM AS AN ENGINEERING SYSTEM? ROBUST SYSTEM (sensitivity looks pretty good to me...) WE CAN ADD A SECTION LIKE THAT HERE
Our combined team of biologists and engineers was working on the E.coli 's ability, first, to recognize two different inputs (here we used two different chemicals), second, to remember which input was presented to them, and third, when confronted with a new input, to recognize whether it is the one that it was trained with or not.
Thereby, the educatETH E.coli 's provide a first step towards the development of biological equivalents to complex engineering building blocks like, e.g. , flip-flops and other logical circuits. We also introduced the concept of double promoters to the [http://partsregistry.org/Main_Page Registry of Standard Biological Parts], which can be helpful for future projects. The concept of learning and recognition plays a major role in different high-level applications like, e.g., recognition of handwriting on a [http://en.wikipedia.org/wiki/Personal_digital_assistant PDA] as well as biological applications. On the other hand, learning plays a major role for living organisms, as well: it enables them to survive by adapting to an ever-changing environment. Therefore, engineering a simple biological system which exhibits learning behavior is of great interest as it can support our understanding of this procedure by comparison with natural systems.
