Day 1 -07/06/18

Started the day with introductory talks explaining iGem and the wiki, we then went onto look at previous competition entries. Jem Stach and Phil Wright spoke about their experience in the field, research interests and what makes a good competition entry.

Day 2 - 08/06/18

The day began with a talk from Jon Marles-Wright about the importance of human practices and the impacts of our projects in the real world. This was followed by Dana Ofiteru who taught us about mathematical modeling of biological systems. In the afternoon, plant biologist Max Kapralov discussed using synthetic biology to improve the efficiency of photosynthesis. Finally, Rachel Armstrong (professor of experimental architecture) discussed the potential of microorganism in waste management systems and energy production in the built environment. Rachel also outlined political and economic issues surrounding synthetic biology.

Day 3 - 11/06/18

We started the day with a talk from Angel Goni Moreno who discussed the principles of synthetic biology and provided guidance on the implementation of logic in Biology. The Masters students who are working on the Interlab study explained their role in the project and we brainstormed ideas. Following this, the Synthetic Biology Masters students discussed their individual projects involving modelling lab work. Each of the team gave a presentation on a previous competition entry that has won an award.

Day 4- 12/06/18

We started the day with a talk from Alice banks and Colette Whitfield. Followed by brainstorming with Tom, refining the original ideas with some extra. Then the marine biologist/Engineered talked to us about boat fouling. Finally we had a talk from Vas Andriotis who focused on plant biology (corn yield). Finishing with brainstorming.

Day 5- 13/06/18

The day began with a talk from Martyn Dade-Robertson who discussed the use of biotechnology in architecture and his research into pressure sensing E.coli. In the afternoon Harold Freemann led a discussion around the use of mathematical modelling and its uses in synthetic biology. Finally Alice Banks and Colette Whitfield covered current topics in synthetic biology and the equipment available to us in the laboratory.

Day 6- 14/06/18

This was our first day in which we were given freedom to explore our ideas and gain a necessary background surrounding the topics in order to refine into 6 ideas that will be pitched to research supervisors and the guest speakers who have given presentations since the project began.

Day 7- 15/06/18

We continued to explore our ideas for the majority of the day, narrowing our proposals down from ten ideas to six. We worked more as individuals, researching specific aspects of the proposals.

Day 8- 18/06/18

Today was more orientated around the ethical implications Synthetic Biology has. We started with a discussion with Dr. Ilke Turkendag, a lecturer in Law Innovation & Society. We discussed our six proposals and outlines possible ethical/legal issues which could arise. This was followed by an interesting talk from Simon Woods and Ken Taylor, they spoke about potential stakeholders and how we could go about talking/communicating with them. They also took each of our ideas and looked at the potential impacts our projects could have on the wider public. We then finished the day preparing for our six pitches on Tuesday. The OpenTrons OT-2 robot, which the Newcastle iGEM team won, was also delivered today¹.

Day 9- 19/06/18

We pitched the six ideas that had been selected to the advisers and masters students. After receiving feedback and suggestions from the advisory team we narrowed it down to two ideas to be taken forward. Further we constructed a template for both idea presentations and allocated team members to each idea. Umar is now our least favorite team member :)

Day 10/11- 21/06/18

Following on from the 2 ideas that we chose to take forward, we spent these next 2 days researching further into these proposals. During our research, we took a holistic approach when evaluating our ideas and attempted to account for topics such as human practices, ethical implications and possible art and design ideas. We incorporated this into our 2 ideas which we then pitched to the supervisory team and Master's students. We also managed to successfully setup the OT-2 robot. The smiles speak for themselves...

Day 12- 22/06/18

This day was used to carefully consider both ideas that were pitched the previous day before voting on one to take forward. We started by summarizing each idea in 140 characters which highlighted some discrepancies in individual team members understanding of the ideas. After these discrepancies were rectified, the team spent some time considering each idea before voting on one to take up as our project. In the end, it was decided that the project involving engineering microbes to colonize plant roots and attract nitrogen-fixing bacteria was the best to take forward. We spent some time thinking about the modeling/human practices/lab work that may be involved in this project.

Day 13- 25/06/18

On our first official day of project-specific work, various tasks were allocated to team members for them to research. Some background reading was conducted on the topic, the team name was confirmed and some ideas for the team logo were suggested. Also, some ideas for a hydroponics system were discussed. With a rare bit of sunshine, we decided to work outdoors.

Week commencing: 25/06/18

On the Monday, members of the team were provided an overview of the plant growth facilities at Newcastle University by Vas Andriotis who has shown great interest in our project since its pitch and has given many resources to enhance and develop our ideas. The remainder of the group began on the research for the several experiments that will be ran in parallel over the Summer.
Tuesday was dedicated to further fleshing out our research by identifying species which would be suitable for our iGEM project. Some members moved in an artistic direction and produced a handful of potential logos before the entire team voted on our two favorites *put logos here*. Once these were decided, merchandising began development.
Development on our hydroponics system moved into full swing on the Wednesday, with our 2 engineers beginning work on the general structure of the system which has been influenced by conversations with plant biologists within the university; working once again with Vas in order to understand his needs from the system.
Thursday presented our team with the incredible opportunity to speak with Steven Burgess who is currently performing plant research at the University of Illinois in order to discuss our project and identify potential for sharing our work among the wider scientific community.
Members of the Biology and Engineering teams went to meet with Dr Montero-Calasanz; a Microbiologist whom specialises in plant-microbe interactions. This gave a valuable opportunity to identify potential protocols which would relate to our chassis organism. The week was rounded off by talks from Alice Banks and Collette Whitfield concerning sponsorship and outreach.

Week commencing: 02/07/18

The team focused on preparation for the wetware projects by ordering the Pseudomonas chassis, in addition to various free-living nitrogen-fixing bacteria. A variety of flavinoid chemoattractants were also ordered in order to reduce the wait time before lab work begins. The human practices and outreach team continued getting their work by in touch with potential sponsors. Some of the team members with prior experience in programming began working with the OT-2 to design a heat-shock protocol for E. coli using the python-based language within the OpenTrons API. The whole team received inductions for the Cat2 lab so that we can begin the wetware side of the project and follow all the safety protocols ans rules and regulations set out by the University for safe lab use. After receiving the lab inductions, we prepared the lab equipment for testing Arabidopsis germination so that we can begin testing the following week.

Week commencing: 09/07/18

The ball started to roll this week, we managed to get access to the labs and plant our first set of seeds in agar as well as preparing competent E. coli cells. We began the process of styling our wiki using bootstraps and designing the poster for the European Meetup. Towards the end of the week we attended a modeling workshop, ran by Synthetic Biology Masters students, this gave us an insight into modelling and tips we can apply to our modeling work. The team was also lucky enough to recieve goodiebags of Eppendorf².

Week commencing 16/07/2018

This week was full of action. The architects in the team 3D printed a cold deck for the OpenTrons OT-2 and laser cut accompanying trays to hold test tubes. Now that we have the cold deck we can manufacture trays to hold lots of different apparatus increasing the number and complexity of experiments we can carry out on the OpenTrons. In addition, we had a meeting with Martyn Dade-Robertson from the School of Architecture, Planning & Landscape; he spoke to us about the importance of finding a context in which to situate our human practices, once we have this it will provide the design parameters necessary to progress. Finally, stencils were made for the 'Alternative Roots' logo enabling us to tag any hardware we build.
Some of the team also travelled to Munich this week for the European iGEM meetup. Those who attended throughly enjoyed liasing with other iGEM teams as well as the event organisers and speakers. The team's poster was on display at the meetup which gathered some interest around our project as well as many questions and suggestions for improvement which have been duly noted by the team for further consideration. Potential collaborations were also sought after in Munich.
Lab work for the chemotaxis assays commenced with trial runs using the DH5α E. coli control in order to test the protocol. It was noted from these attempt that the concentration of naringenin was too high as the plates did not show signs of growth for 2 days; after which, signs of growth were minimal. The concentration was diluted to 100µM and 50µM for future trials to see if this would overcome the issue.

Week commencing 23/07/2018

The long-awaited Pseudomonas fluroescens arrived this week,having come all the way from Germany, meaning our iGEM team could start preparation for the transformation process. The team worked with Dr Montero-Calasanz to make initial agar and liquid cultures in both LB and TS mediums and now have enough bacteria to start the initial transformation experiments.
This week the some of the parts for the hardware arrived meaning we could get underway with the construction of the hydroponics. First the basic circuit for the LED lights was created, the code we used to control these lights was an adaptation of a freely available library (FastLED) which can be found online. We made minor adjustments to suit our requirements, for example the light intensity was increased. Our micro-controller (Arduino), was then loaded with this edited code. This device will be responsible for monitoring and maintaining our entire system. We faced issues with timing the lights for a 16 hour day and 8 hour night cycle. We decided to use a ‘count’ within a loop to control when the LED’s need to be turned off. This meant we had to calibrate for the time a single loop took and multiply that up for 16 hours. We are currently waiting for some parts to arrive so that we can begin construction of an automated switching circuit.
The week was rounded off with a presentation to the stakeholders in the project, such as the PI's and advisers, to provide an update on how the project has progressed thus far. The presentation also offered a valuable opportunity to highlight areas of the project that needed to be strengthened and was a good opportunity to develop our presentation skills prior to the Jamboree in Boston.
