APPLY TO JOIN US IN 2012
The Brown and Stanford iGEM teams are planning to continue our transcontinental collaboration in the upcoming year. If you are a student at either of our universities and are interested in participating, please follow the recruitment instructions for your location!
Still confused about exactly what Synthetic Biology is? Not to worry, here's an awesome video explaining it! http://www.youtube.com/watch?v=rD5uNAMbDaQ&feature=youtu.be
For Stanford students
Please fill out our interest form at https://docs.google.com/spreadsheet/viewform?formkey=dEQyaWdReTN5S2pCcHRVY29hQXh4cHc6MQ.
Applications will be due Sunday, February 5th at 11:59 PM. Please fill out the application form here, and also attach your resume and (unofficial) transcript and email them to email@example.com.
We'll be holding some lab technique boot camps and brainstorming/planning sessions in the spring if you make the team, so expect that. If you're chosen, you should also take Dr. Drew Endy's BioE 44 Synthetic Biology Lab in the spring, which is, by the way, an awesome class.

Mars BioTools: Synthetic Biology for Space Exploration
One of the major challenges of space exploration is the limited payload mass that can be launched on a rocket and the difficulty of resupply mid-mission. Any long term settlement will require more resources than astronauts can initially bring with them. Synthetic Biology has the potential to revolutionize space exploration and settlement. Biological tools have a major advantage over classical tools: the ability to self-replicate and regenerate.
The emerging field of Synthetic Biology will allow us to engineer microbial factories that will largely circumvent the limiting payload factors. These cellular factories will generate fuel, food, medicines and building materials for settlers, but will consist of engineered cells that could be stored in a single test tube, and regrown to production scale on-site, as needed.
The Brown-Stanford iGEM team is excited to work on three different projects, under the common theme of developing Synthetic Biology applications for space. In addition, as a response to the ethical and philosophical considerations, we interviewed prominent researchers and leaders in the field. Click on the astronaut in the corner to view our series.
Any extra-terrestrial settlement will require a habitat to keep its occupants alive, but transport of such a habitat will require a huge amount of payload space. RegoBricks uses bacteria to cement Martian and Lunar regolith (soil) simulant into durable building blocks, similar to concrete bricks, allowing settlements to use in situ resources to build structures.
Biological interfaces cannot pass information to their users as fast as electronic ones can. FRETcetera develops a novel method of fast-acting biological reporting with changes in cell fluorescence. Bacteria could be used to detect toxic chemicals in the environment, for example, or inform astronauts that their microbial tools are unhealthy.
All biological tools need energy to run. PowerCell develops a universal energy source. Engineered photosynthetic bacteria generate carbon and nitrogenous nutrients from sunlight and air and secrete them to power biological tools. These tools will transform the raw materials into fuel, building materials, food, drugs, and other products useful to settlers.
We did very well at iGEM this year!
-At the Americas Regional Jamboree, we finished Top 4 and won Best Presentation.
-At the World Jamboree, we finished in the Sweet 16, and won Best New Application.
We are extremely grateful to all those who helped us along the way, and our mentors. Thank you so much!
Here's a minute long teaser of our project!
Latest Advancements on Projects
Anabaena Transformation and Successful Cell-Type Specific Expression Control
We successfully transformed our cyanobacterial chassis, Anabaena PCC 7120, with our designed PowerCell genetic construct. Unlike more common cyanobacteria species such as Synechocystis PCC 6803 or Synechococcus elongatus PCC 7942, Anabaena is not naturally competent and does not easily uptake foreign DNA. We performed a triparental conjugation in order to bypass the natural barriers to transformation.
To demonstrate that expression of our construct is properly co-localized to vegetative cells, we grew cultures of Anabaena in nitrate-free BG11 media to promote heterocyst formation. We demonstrated the successful control of our pSac promoter over our sugar secretion construct through GFP expression. The sugar secretion construct is only expressed in actively photosynthesizing cells. In the first picture, we observe areas of diminished GFP fluorescence at regular intervals (approximately 1 in 10 cells) along our transformed Anabaena filament (the background fluorescence is likely due to chlorophyll). Since our GFP reporter should only express under the pSac promoter and only in non-heterocyst cells, we would expect the spacing of dark spots to match the spacing of heterocysts identified through alcian blue staining. Alcian blue is a dye that selectively binds to polysaccharide chains on the surface of heterocyst cells. As you can see by comparing the two images, our results appear to match up!
Work to characterize the performance of our cscB sucrose secretion construct is underway. We will assay sucrose levels produced by PowerCell. If they are high enough, we will attempt to grow E. coli W. containing arbitrary biobricks from this nutrient source, in an attempt to show PowerCell can power biological tools.
Transformed Anabaena showing cell-type specific GFP fluorescence under the control of the pSac promoter. GFP expression is on in vegetative cells, off in heterocysts. Some background fluorescence from chlorophyll is visible.
Transformed Anabaena with heterocysts stained by alcian blue. Heterocyst spacing corresponds to the "off" cells from the GFP image, implying that the sucrose secretion construct in not active in heterocysts, as desired.
Biobricked the urease operon
We successfully PCR cloned a 10.7 kb functional urease cassette from the plasmid pBU11, whose genetic sequence has hitherto never been known before. We ligated it onto a backbone, and successfully made a standard BioBrick, characterizing its function and demonstrating active urease activity. Urease is the catalyst behind the phenomenon known as biocement, which is able to fuse sand into bricks, using nothing more than calcium ions and urea. More about urease.
Biobrick part BBa_K656013 has been submitted to the Registry of Standardized Parts. The sequence of this cassette is unavailable because it currently does not exist in any known registry. At the time of this writing, it is currently being sequenced in the lab of Dr. Chris Mason at Weill Cornell Medical College. As soon as the sequence is available, we will supplement the directory listing.
Stratospheric Balloon Flight
We launched samples of our bacteria to the far edge of space (80,000 ft-110,000 ft) to test for their ability to survive simulated Martian environmental conditions. The pressures, temperatures, and radiation conditions at these altitudes are similar to the conditions on the Martian surface. Read about our escapades here
Advancements in Human Practices
