'''We have achieved many of the goals we planned at the beginning of our project. These achievements are well distributed between [[Team:ETH_Zurich/expresults|experimental results]], [[Team:ETH_Zurich/modeling/overview|theoretical work]] and [[Team:ETH_Zurich/human/overview|human reflection and socialisation]]. As a [[Team:ETH_Zurich/team|team of seven students]], we all contributed to all achievements and this is why everyone of us can feel the fruitfulness of such a wide project. '''

We highlighted 3 levels of [[Team:ETH_Zurich/expresults#Quorum_Sensing|crosstalk]] between Las, Lux and Rhl quorum sensing systems and fully quantitatively characterized all possible combinations of  crosstalk at these three levels.

=== [http://2014.igem.org/Team:ETH_Zurich/expresults#Quorum Characterizing and reducing leakiness in quorum sensing systems] ===
[[Team:ETH_Zurich/expresults#Riboregulators|We quantitatively characterized]] leakiness of the three quorum sensing systems (Las, Lux and Rhl). We have designed a new BioBrick for reducing leakiness of these systems and demonstrated its efficiency for the ''lux'' system, which is the most leaky of the three. We improved the signal over noise ratio for this promoter by a factor of 6 while reducing the basal expression by a factor of 60.

[[Team:ETH_Zurich/lab/chip#Time-Lapse_Movies|Bead to bead communication]] could be observed by placing a sender bead, containing AHL producing cells, into one well of our millifluidic chip connected to another well containing a receiver bead, which contains cells, that produce green fluorescent proteins upon AHL induction.

Based on the data presented in  Bonnet et al.'s publication "Amplifying genetic logic gates"<sup>[[Team:ETH_Zurich/project/references#refEmergence|[9]]]</sup>, we parameterized a detailed model, resulting in predictions for  a significant number of parameters currently not documented in the literature, such as binding affinity of integrases to their sites on the DNA.

We conducted a deep study of complexity, how it emerges, and how we should deal with it. By [http://2014.igem.org/Team:ETH_Zurich/human/interviews interviewing experts] from different fields and by listening to the public with a [http://2014.igem.org/Team:ETH_Zurich/human/survey survey], we have broaden our views. Our own biological project also raised questions on this subject and we finally integrated everything that we learnt in [http://2014.igem.org/Team:ETH_Zurich/human/essay a reflection of our own].
