<p> Our genetic circuit is activated/deactivated by the redox state of the transcription factor (SoxR). SoxR oxidation is modulated by  small redox molecules, such as the redox-cycling drug pyocyanin.  We realized that using another cheaper redox molecule could not only replace inducer molecules such as IPTG due to their price, but also make our system cheaper to use. Using PMS which is a small redox molecule, we can activate a gene much like IPTG would with p<i>lac</i>. Not only is PMS far cheaper than both pyocyanin and IPTG, it is also non-toxic and makes our system more applicable for real world applications. Experimental data can be found here:</p>

<p>A big socio-ethical issue with using genetically engineered organisms is the issue of biocontainment. We recognized this as an issue by talking to members of the public as well as from the socio-ethics discussion. These organisms should not be released where they could potentially cause ecological damage by outcompeting or harming native species. While some may debate the impact of this ecological damage, it would be easier to persuade governments and its people to use GMOs when proper biocontainment measures are in place. This is especially true for our project. By transcribing growth retardants or toxins, like gp2 and MazF respectively, we can control where our bacteria will live and thus add a layer of biocontainment.

<p>In preparation for our art exhibition, we discussed the integration of science and art with a student from the RCA. She mentioned that in fashion, chemical pollution as a result of the usage of dyes is prominent. We realized that using bacteria to synthesize dyes could provide for an ecologically friendly solution. Moreover, with the ability to pattern using our electrode array, we can design simple prints using MelA which is a step in the right direction for the fashion industry. We have also succeeded in cloning the MelA gene into our construct design. Experimental data can be found here:</p>

<p>When we started our project, many of us had personal as well as interpersonal issues that threatened the viability of our project as well as our own well-being. We made it a point to reflect upon this experience and wondered if any other teams had similar issues to us. We surveyed 67 people from 13 different iGEM teams and developed a team-communication application called Let's Talk about It! as a aid for resolving these issues both for us and future iGEM teams. Most importantly, we have used the app to raise important issues with our PIs and supervisors and have these issues responded to as fast as possible. Knowing that this tool exists has made us more open about our issues and help each other communicate solutions for these issues. This has raised our productivity and made us more cooperative.
