| |
| - | The focus of this meeting was to finalize the project proposal, now found at [[Team:BCCS-Bristol/Project]]. On the modelling side, we delegated GRNs to Petros/Antos, vesicles to Steve, magnetotaxis to Emily and performance/population dynamics to Mattia. Lab work progresses.

| |
| - | The project has gained a direction and a lot of work has been done in both modelling and wet-lab aspects. A review of the project and its goals was given to all advisors and views about further work.
| |
| - |
| |
| - | We are improving BSim to have a more "real-life" feeling. Current progress includes the shape of bacteria and population dynamics.

| |
| - | Discussed the progress of the project. We are currently focused on the vesicle formation part of the project although some steps have been taken in trying to develop magnetotaxis ''ex vivo''.

| - | ====Vesicles with a twist...part II====
| |
| - | After a week's worth of digging through the literature we have managed to find possible '' non-toxic '' candidate proteins that pack within outer membrane vesicles produced by E.coli. Thus we have settled into implementing directed communication and delivery of proteins of interest between different cells/populations. This will possibly form the bigger part of the project and if time permits we will combine this with our ''magnetotaxis'' idea.
| |
| - |
| |
| - | With respect to [https://2009.igem.org/Team:BCCS-Bristol/Modeling modelling ] we are interested in developing a useful tool for the community and research by possibly expanding the existing BSim software. For further information visit the [https://2009.igem.org/Team:BCCS-Bristol/Modeling modelling ] page of the wiki.
| |
| - |
| |
| - | With respect to the lab we will pursuit the building of biobricks that will allow the implementation of proteins of interest into OMVs (outer membrane vesicles) as a first part to the project. Upon the succesful completion of this first task we want to implement some GRN for the control of responses of both production and/or message acceptance.

| - | ====Vesicles with a twist====
| |
| - |
| |
| - | We seem to have settled down to the idea that implementing magnetotaxis ''in vivo'' in E.coli will be infeasible within the given time-frame. Instead we have decided to move in the direction where we will try implementing the usage of vesicles in our project.
| |
| - |
| |
| - | We are still thinking of perhaps implementing magnetotaxis combined with bacteria in an ''in vitro'' manner.

| - | ==== Bacterial diagnosis ====
| |
| - |
| |
| - | Ollie and Thanasis spent some time this week looking into whether we could use bacteria to detect and report on the state of an organism. It now seems we have now dropped the idea on the grounds it is too similar to projects attempted in previous years (NYMU, KULeuven) and would require licensing. However there was a suggestion that this idea could be taken in the direction of sequence based toggle switches to carry out a (more complicated) decision tree based diagnosis.

| |
| - | The shortlist was down to 7 projects and 3 of those made it to the next round as voted by the present audience. These are as follows (project title, (votes received)):
| |
| - |
| |
| - | * Magnetic Bacteria (10)
| |
| - | * Bacterial Vesicles (6)
| |
| - | * Non-Invasive Reporting/Switches & Sensors (6)
| |
| - | * Genome Updates & version control (5)
| |
| - | * Host/Parasite Symbiosis (3)
| |
| - | * Bacterial Computation
| |
| - | * RNA Editing
| |
| - |
| |
| - | Thus the top three were chosen to review the literature further and assess the possibility of carrying each out in 3 months.
